Abstract

The application relates to a mounting adjustment assembly and a multimedia device. Based on the application, the installation adjusting component can be utilized to realize the splicing installation of the first panel and the second panel. The mounting adjustment assembly includes a first connecting member, a second connecting member, and an adjustable locking assembly. The adjustable locking assembly enables the second panel to be in a preassembled state suspended adjacent to the first panel by hooking the second connection frame to the first connection member, and enables the second panel in the preassembled state to be splice-mounted with the first panel by inducing a positional shift of the second connection member to the first connection member in response to an external locking operation. The operation stroke of the external locking operation can control the position offset of the second connecting member, so that the panel matching size between the second panel and the first panel which are spliced and installed can be adjusted by controlling the position offset, and further, the panel splicing error of the first panel and the second panel during splicing and installation can be restrained.

Description

Installation adjusting assembly and multimedia device

Technical Field

The present application relates to a mounting technology of a multimedia device, and more particularly, to a mounting adjustment assembly and a multimedia device using the same.

Background

The multimedia device can be applied to various scenes related to information communication such as teaching, exhibition and meeting. The multimedia device may include a main panel, such as a display panel, to utilize the main panel to present (e.g., screen display) subject matter associated with the information to be communicated. And, the multimedia device may additionally include a sub-panel such as a handwriting panel to present (e.g., handwriting graffiti) additional content for supplementing the refined subject content with the sub-panel during the information exchange.

In order to enhance the combined presentation effect of the main panel and the sub-panel, the sub-panel may be splice-mounted with the main panel in the panel splice direction of the main panel. Furthermore, the splice mounting of the main panel and the sub-panel can be achieved by mounting both the main panel and the sub-panel on the same integrated bracket.

In general, there may be a machining error of the integrated bracket, which may cause an unregulated position deviation of the installation position of the sub-panel with respect to the main panel, and the position deviation of the installation position may cause a panel splicing error such as a splicing interference or a clearance fit between the main panel and the sub-panel. For example, a splice interference refers to an interference fit in which the splice edges of the primary and secondary panels are pressed against each other, and the splice interference may cause stress deformation of at least one of the primary and secondary panels. For another example, the clearance fit may affect the combined appearance of the primary and secondary panels.

Therefore, how to suppress panel splicing errors of the main panel and the sub-panel during splicing and installation becomes a technical problem to be solved in the prior art.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below by referring to the accompanying drawings and examples.

Fig. 1 is a schematic diagram showing an assembled structure of a mounting adjustment assembly in a first embodiment of the present application. Fig. 2 is an exploded view of the installation adjusting assembly in the first embodiment of the present application. Referring to fig. 1 and 2, in a first embodiment of the present application, a mounting adjustment assembly for achieving a splice mounting may include a first connection member 10, a second connection member 20, and an adjustable locking assembly 30.

Fig. 3 is a schematic view showing a mounting state of a first connection member of a mounting adjustment assembly in a first embodiment of the present application. Referring to fig. 3, in the first embodiment of the present application, the first connection member 10 may be used to be fixedly installed at the rear surface of the first panel 50, and the rear surface of the first panel 50 may refer to an opposite surface of the content presentation surface of the first panel 50 in the panel thickness direction of the first panel 50. Illustratively, the first panel 50 may have a first panel mating edge 55, and the first connecting member 10 may be adapted to be fixedly attached to the rear face of the first panel 50 at the first panel mating edge 55 of the first panel 50.

Illustratively, in embodiments of the present application, the first panel 50 may include a display panel such as an LCD (Liquid CRYSTAL DISPLAY, liquid crystal first panel). If the first panel 50 includes a display panel, the content presentation surface of the first panel 50 may be a display panel of the display panel, the rear back surface of the first panel 50 may be a rear cover surface of the display panel located opposite to the content presentation surface in a panel thickness direction of the display panel, the rear cover of the display panel may have a rear cover convex hull 51 for accommodating the electrical components, and the first panel splice edge 55 of the first panel 50 may refer to an edge region located outside the rear cover convex hull 51 of the display panel.

Illustratively, in embodiments of the present application, the first panel joint edge 55 of the first panel 50 may include a side edge of at least one side in the panel width direction of the first panel 50. For example, in the illustration of fig. 3, both of the opposite sides in the panel width direction of the first panel 50 are taken as the first panel joint edge 55 as an example, that is, both of the opposite sides in the panel width direction of the first panel 50 may be used for joint mounting.

Fig. 4 is a schematic view showing a mounting state of a second connection member of the mounting adjustment assembly in the first embodiment of the present application. Referring to fig. 4, in the first embodiment of the present application, the second connection member 20 may be used to be fixedly installed at the rear surface of the second panel 60, and the rear surface of the second panel 60 may refer to an opposite surface of the content presentation surface of the second panel 60 in the panel thickness direction of the second panel 60. Illustratively, the second panel 60 may have a second panel mating edge 65, and the second connecting member 20 may be adapted to be fixedly attached to the rear face of the second panel 60 at the second panel mating edge 65 of the second panel 60.

Illustratively, in embodiments of the present application, the panel type of the second panel 60 may be the same as the panel type of the first panel 50, or the panel type of the second panel 60 may also be different from the panel type of the first panel 50. If the first panel 50 includes a display panel, i.e., the panel type of the first panel 50 is a display panel, and the panel type of the second panel 60 is different from the panel type of the first panel 50, the panel type of the second panel 60 may be a handwriting panel, i.e., the second panel 60 may include a handwriting panel (e.g., a blackboard or a whiteboard).

For example, in the pictorial representation of fig. 4, the second panels 60 respectively splice-mounted with the first panel 50 on different sides in the panel width direction of the first panel 50 are shown, and for the second panels 60 splice-mounted with the first panel 50 on different sides, the second panel splice edges 65 may be side edges on different sides in the panel width direction.

Fig. 5 is a schematic view showing the effect of the installation adjusting assembly in the first embodiment of the present application in implementing splice installation. Referring to fig. 5, in a first embodiment of the present application, the adjustable locking assembly 30 may be used to effect a splice installation between the first panel 50 and the second panel 60 in cooperation with the first and second connection members 10, 20, and may also adjust the panel mating dimension between the splice installed first and second panels 50, 60, e.g., between the first and second panel mating edges 55, 65 of the first and second panels 50, 60.

For example, the splice mounting of the first panel 50 and the second panel 60 may be such that the first panel 50 and the second panel 60 are each spliced adjacently in a vertically-horizontally-disposed posture. Wherein, "vertical" in vertical transverse may refer to both the panel height direction of the first panel 50 and the panel height direction of the second panel 60 being parallel to the vertical direction Y, "transverse" in vertical transverse may refer to both the panel width direction of the first panel 50 and the panel width direction of the second panel 60 being parallel to the first horizontal direction X, and the first panel 50 and the second panel 60 may be splice-mounted along the first horizontal direction X. In the case where the first panel 50 and the second panel 60 are vertically laid horizontally, the panel thickness direction of the first panel 50 and the panel thickness direction of the second panel 60 are both parallel to the second horizontal direction Z perpendicular to the first horizontal direction X.

In order to better describe the principle of the installation adjusting assembly of the present application for implementing the splice installation using the above-described directional definition, hereinafter, the first horizontal direction X will be referred to as the panel splice direction of the first panel 50 and the second panel 60, the second horizontal direction Z may be understood as the panel thickness direction when the first panel 50 and the second panel 60 are in the vertically-horizontally-placed state, and the vertical direction Y may be considered as the panel height direction when the first panel 50 and the second panel 60 are in the vertically-horizontally-placed state.

In a first embodiment of the present application, the adjustable locking assembly 30 may be used to mount the second connection member 20 to the first connection member 10 in a hanging manner (e.g., the adjustable locking assembly 30 may be preloaded onto the second connection member 20 prior to the second connection member 20 being mounted in a hanging manner). Wherein the hooking direction of the hooking installation of the second connection member 20 may intersect the panel-joining direction X of the second panel 60 and the first panel 50, for example, the hooking direction of the hooking installation of the second connection member 20 may be parallel to the panel-height direction Y, the second panel 60 is in the pre-assembled state after the second connection member 20 is hooked installation, i.e., the hooking installation of the second connection member 20 serves to place the second panel 60 in the pre-assembled state, and the second panel 60 in the pre-assembled state may be suspended to be spaced adjacent to the first panel 50 in the panel-joining direction X, i.e., in a fit state in which the first panel 50 and the second panel 60 (e.g., the first panel-joining edge 55 of the first panel 50 and the second panel-joining edge 65 of the second panel 60) are in a clearance fit when the second panel 60 is in the pre-assembled state.

In a first embodiment of the present application, the adjustable locking assembly 30 may also be used to actuate the second coupling member 20 to be hitched to produce a first positional offset proximate to the first coupling member 10 in response to a received external locking operation (e.g., manually or by manual operation with an auxiliary tool). Wherein a first positional displacement of the second connection member 20 near the first connection member 10 is used for splice-mounting the second panel 60 in the pre-assembled state with the first panel 50 in the panel splice direction X, the first positional displacement of the second connection member 20 near the first connection member 10 is controlled by an operation stroke of an external locking operation, and the first positional displacement of the second connection member 20 near the first connection member 10 is used for adjusting a splice-fit dimension in the panel splice direction X between the second panel 60 and the first panel 50 (e.g., between the first panel splice edge 55 of the first panel 50 and the second panel splice edge 65 of the second panel 60), for example, the adjustment result of the splice-fit dimension may be smaller than a gap dimension of a gap fit when the second panel 60 is in the pre-assembled state.

Referring back to fig. 1 and 2, in a first embodiment of the present application, the adjustable locking assembly 30 may include a support bar 31 and an eccentric member 35.

In the first embodiment of the present application, the support rod 31 of the adjustable locking assembly 30 may be used to perform the hooking and mounting function of the adjustable locking assembly 30 to the second connection member 20, i.e., the support rod 31 of the adjustable locking assembly 30 may be used to hook and mount the second connection member 20 to the first connection member 10 with the second panel 60 in the pre-assembled state described above.

In the first embodiment of the present application, the support rod 31 of the adjustable locking assembly 30 may also perform a response operation to any one of an external locking operation and an external unlocking operation in cooperation with the eccentric member 35, thereby realizing the function of the adjustable locking assembly 30 to splice-mount the first panel 50 and the second panel 60 and adjust the splice-fit size. Wherein the response operation cooperatively performed by the support bar 31 and the eccentric member 35 may include driving the second coupling member 20 to generate a first position offset close to the first coupling member 10 in response to the external locking operation, and driving the second coupling member 20 to generate a second position offset far from the first coupling member 10 in response to the external unlocking operation. In this case, the eccentric member 35 of the adjustable locking assembly 30 may be used to withstand an external locking operation, the eccentric member 35 being movably connected with the support bar 31, and the eccentric member 35 may also be used to:

The first eccentric rotation occurs in response to the external locking operation, and the first eccentric rotation induces the first positional displacement of the hitched second coupling member 20 in the panel joining direction X near the first coupling member 10 based on the movable coupling of the eccentric member 35 with the support rod 31 to mount the second panel 60 with the first panel 50 in the panel joining direction X using the first positional displacement and adjust the joining fit dimension between the second panel 60 and the first panel 50 (e.g., between the first panel joining side 55 of the first panel 50 and the second panel joining side 65 of the second panel 60) in the panel joining direction X.

As can be seen from the above, in the first embodiment of the present application, the adjustable locking assembly 30 can place the second panel 60 in the pre-installed state suspended adjacent to the first panel 50 in the panel-joining direction X by hooking the second connection frame 20 to the first connection member 10, and the adjustable locking assembly 30 can place the second panel 60 in the pre-installed state in the first panel 50 by causing the first position of the second connection member 20 to be offset toward the first connection member 10 in response to the external locking operation. Wherein the adjustable locking assembly 30 can control the offset of the first positional offset of the second connection member 20 by responding to the external locking operation, that is, the operation stroke of the external locking operation can control the offset of the first positional offset of the second connection member 20, and can adjust the panel fitting dimension at the time of the splice installation between the splice-installed second panel 50 and the first panel 60 by controlling the offset of the first positional offset of the second connection member 20, and further can suppress the panel splice error (for example, splice interference or clearance fit, etc.) of the first panel 50 and the second panel 60 at the time of the splice installation by adjusting the panel fitting dimension.

Moreover, in the first embodiment of the present application, the second panel 60 is always in the preassembled state based on being hung by the adjustable locking assembly 30 during the panel fitting size adjustment based on the response to the external locking operation, and therefore, the operator of the external locking operation does not need to apply an auxiliary force such as lifting or raising to the second panel 60, thereby making the panel splice error adjustment process of the splice installation easy.

In addition, in the first embodiment of the present application, the adjustable locking assembly 30 may also support the release of the splice installation, i.e., the adjustable locking assembly 30 may also be used to drive the second connecting member 20 to generate a second positional offset (i.e., a reverse offset of the first positional offset) away from the first connecting member 10 in the panel splice direction X in response to an external unlocking operation (e.g., a reverse operation of the external locking operation). Wherein the second connecting member 20 is offset from the second position of the first connecting member 10 for restoring the second panel 60 splice-mounted with the first panel 50 to the pre-assembled state described above in the panel splice direction X.

In this case, in the first embodiment of the present application, the eccentric member 35 of the adjustable lock assembly 30 may also be used to withstand an external unlocking operation, and the eccentric member 35 may also be used to:

a second eccentric rotation opposite to the first eccentric rotation occurs in response to the external unlocking operation, and the second eccentric rotation induces a second positional deviation of the second connection member 20 in the panel splicing direction X away from the first connection member 10 in the panel splicing direction X based on the movable connection of the eccentric member 35 with the support rod 31, wherein the second positional deviation is a reverse deviation of the first positional deviation in the panel splicing direction X to restore the second panel 60 splice-mounted with the first panel 50 to the pre-mounted state described previously.

That is, in the first embodiment of the present application, the eccentric member 35 of the adjustable locking assembly 30 may be caused to be eccentrically rotated either first or second in response to either one of the external locking operation and the external unlocking operation, respectively, causing the second connection member 20 to be eccentrically rotated either to be eccentrically rotated first in the splicing direction X, or to be eccentrically rotated second in the splicing direction X, away from the first connection member 10, respectively.

In the first embodiment of the present application, the second panel 60 restored to the preassembly state may be detached by releasing the hooking installation of the second connection member 20 at the first connection member 10, for example, the releasing of the hooking installation may be achieved by a lifting operation in the opposite direction to the hooking direction.

For a better understanding of the first embodiment of the present application, a detailed description will be made below regarding the structure of each part of the installation adjusting assembly.

Illustratively, in the first embodiment of the present application, the first coupling member 10 may include a hooking groove 13 for hooking installation of the second coupling member 20, and the support rod 31 of the adjustable locking assembly 30 may be inserted into the second coupling member 20. In this case, the supporting rod 31 of the adjustable locking assembly 30 may be slid into the hooking groove 13 of the first connecting member 10 in a posture parallel to the panel splicing direction X, and the hooking installation of the second connecting member 20 inserted with the supporting rod 31 at the first connecting member 10 is achieved by the hooking cooperation of the supporting rod 31 and the hooking groove 13, so as to improve the stability of the hooking installation of the second connecting member 20, and further, the stability of the preassembly state of the second panel 60 may be improved. When the first connecting member 10 is fixedly mounted on the vertically and horizontally disposed first panel 50, the slotting direction of the hooking groove 13 of the first connecting member 10 may intersect the panel splicing direction X, for example, the slotting direction of the hooking groove 13 of the first connecting member 10 may intersect the panel splicing direction X (e.g., parallel to the panel height direction Y), and the slotting direction of the hooking groove 13 of the first connecting member 10 may intersect the hooking direction image of the second connecting member 20 with the panel splicing direction X (e.g., parallel to the panel height direction Y).

Fig. 6 is a schematic structural view of a first connection member of the installation adjusting assembly in the first embodiment of the present application. Referring to fig. 6, illustratively, in a first embodiment of the present application, the first connection member 10 may include a first fixed base plate 11 and a first support riser 12.

Illustratively, in the first embodiment of the present application, the first fixing substrate 11 may have a first fixing substrate mounting hole 110, the first fixing substrate mounting hole 110 may be used to pass through a connection member such as a tapping screw, and the first fixing substrate 11 may be fixedly mounted on the rear surface of the first panel 50 using the connection member passed through the first fixing substrate mounting hole 110. That is, the first fixing substrate 11 is used to fixedly connect the rear surface of the first panel 50.

Illustratively, in the first embodiment of the present application, the first support riser 12 is connected to the first fixing base plate 11, the first support riser 12 is perpendicular to the first fixing base plate 11, and the hooking groove 13 of the first coupling member 10 may be located at the first support riser 12.

Illustratively, in the first embodiment of the present application, the member body of the first connecting member 10 has a plate-like structure, so that the first connecting member 10 can be supported to be formed once by sheet metal forming, die forming or the like, thereby contributing to saving of the member cost of the first connecting member 10.

Illustratively, in the first embodiment of the present application, if the first connection member 10 is formed by sheet metal working, in order to enhance the member strength of the first connection member 10, the first connection member 10 may have a pair of first support risers 12, each of the pair of first support risers 12 has a hooking groove 13 and the opening directions of the hooking grooves 13 of the pair of first support risers 12 are the same, and the pair of first support risers 12 are connected by the connection rib 15 at the opposite sides of the opening of the hooking groove 13, whereby the tensile strength of the first connection member 10 in the direction perpendicular to the first support risers 12 (for example, the panel splicing direction X) may be enhanced.

For example, in the first embodiment of the present application, a pair of first support risers 12 at opposite side edges of the first fixing base plate 11 may be formed by bending regions of opposite sides of the plate material, and the connecting rib 15 connected between the pair of first support risers 12 may be formed by bending edge portions of one of the first support risers 12 toward the other first support riser 12 and welding (e.g., spot welding) with the other support riser 12.

Illustratively, in the first embodiment of the present application, if the first connection member 10 has a pair of first support risers 12, when the first connection member 10 (e.g., the first fixing base 11) is fixedly installed on the rear back surface of the first panel 50, the first support risers 12 may be arranged at intervals in pairs in the panel splicing direction X, the opening directions of the hooking grooves 13 respectively located in the pair of first support risers 12 each intersect with the panel splicing direction X (e.g., parallel to the panel height direction Y), and the hooking installation of the second connection member 20 at the first connection member 10 may be achieved by simultaneously sliding the support rods 31 of the adjustable locking assembly 30 into the hooking grooves 13 of the pair of first support risers 12.

Fig. 7 is a schematic structural view of a second connection member of the installation adjusting assembly in the first embodiment of the present application. Referring to fig. 7, illustratively, in an embodiment of the present application, the second connection member 20 may include a second fixing base plate 21 and a second supporting riser 22.

Illustratively, in the first embodiment of the present application, the second fixing substrate 21 may have a second fixing substrate mounting hole 210, the second fixing substrate mounting hole 210 may be used to pass through a connection member such as a tapping screw, and the second fixing substrate 21 may be fixedly mounted on the rear surface of the second panel 60 using the connection member passed through the second fixing substrate mounting hole 210. That is, the second fixing substrate 21 is used to fixedly connect the rear surface of the second panel 60.

Illustratively, in the first embodiment of the present application, the second support riser 22 is connected to the second fixed base plate 21, the second support riser 22 is perpendicular to the second fixed base plate 21, the second support riser 22 may have a riser insertion through hole 221, and the support rod 31 of the adjustable locking assembly 30 may be inserted (e.g., movably inserted) into the riser insertion through hole 221. Thus, based on the insertion fit (e.g., the movable insertion fit) of the support rod 31 of the adjustable locking assembly 30 with the hole axis of the riser insertion through hole 221 of the second support riser 22, the support rod 31 of the adjustable locking assembly 30 can be inserted (e.g., movable insertion in the panel splicing direction X) into the second support riser 22 of the second connection member 12.

Illustratively, in the first embodiment of the present application, the member body of the second connecting member 20 is of a plate-like structure, and thus, the second connecting member 20 can be supported for one-time molding by means such as sheet metal molding or die molding, thereby contributing to saving of the member cost of the second connecting member 20.

Fig. 8 is a schematic view showing a preassembled state of an adjustable locking assembly for mounting an adjustment assembly in a first embodiment of the present application. Referring to fig. 8, in a first embodiment of the present application, the adjustable locking assembly 30 may be preloaded onto the second connecting member 20 prior to the splice installation of the first panel 50 and the second panel 60. For example, the adjustable locking assembly 30 may be preloaded to the second connection member 20 by inserting the support bar 31 into the second connection member 20 (e.g., removably into the second support riser 22) before the second connection member 20 is mounted in the hanging manner (i.e., before the second panel 60 is in the preloaded state described above).

Illustratively, in the first embodiment of the present application, the supporting rod 31 of the adjustable locking assembly 30 may have an annular clamping groove 314, the annular clamping groove 314 of the supporting rod 31 may be clamped with a limiting spring piece 37, and the limiting spring piece 37 is located on one side of the second supporting riser 22 facing the first connecting member 10, so as to limit the free sliding of the supporting rod 31 facing away from the first connecting member 10 before the second connecting member 20 is mounted on the first connecting member 10 in a hanging manner.

Illustratively, in the first embodiment of the present application, if the second connection member 20 is formed by sheet metal working, the second fixing base plate 21 may have a base plate burring 215 and/or the second supporting riser 22 may have a riser burring 225 in order to enhance the member strength of the second connection member 20.

Illustratively, in the first embodiment of the present application, if the second fixing base plate 21 has the base plate flange 215, the base plate flange 215 is located at the edge of the second fixing base plate 21 perpendicular to the base plate of the second support riser 22, and one end of the base plate flange 215 near the second support riser 22 may be fixedly connected to the second support riser 22 by welding (e.g., spot welding) or the like.

Illustratively, in the first embodiment of the present application, if the second support riser 22 has the riser flanges 225, the riser flanges 225 are located at the riser edges of the second support riser 22 perpendicular to the second fixing base plate 21, and one end of the riser flanges 225 near the second fixing base plate 21 may be fixedly connected to the second fixing base plate 21 by welding (e.g., spot welding) or the like.

Thus, in the first embodiment of the present application, the tensile strength of the second connection member 20 in the direction perpendicular to the second support riser 22 (e.g., the panel splice direction X) may be enhanced based on the base flange 215 and/or the riser flange 225.

Illustratively, in the first embodiment of the present application, the second connection member 20 may further include a hooking flap 23, the hooking flap 23 connecting the second support riser 22 perpendicularly to the riser edge of the second fixing base plate 21, and if the second support riser 22 has a riser flange 225, the riser flange 225 may be located at an opposite side riser edge of the hooking flange 23. For example, when the second connection member 20 (i.e., the second fixing substrate 21) is fixedly mounted to the second panel 60, the hooking flap 23 may connect the upper edge of the second support riser 22 in the panel height direction Y, and if the second support riser 22 has the riser flange 225, the riser flange 225 may connect the lower edge of the second support riser 22 in the panel height direction Y.

Illustratively, in the first embodiment of the present application, if the second connection member 20 includes a hooking flap 23, the hooking flap 23 is bent outwardly from the side of the second support riser 22 adjacent to the first connection member 10, and the hooking flap 23 may be used to hooking engage with the first connection member 10 (e.g., the first support riser 12). Thus, the second connection member 20 may be coupled to the first connection member 10 using the coupling engagement of the coupling flap 23 with the first connection member 10 (e.g., the first support riser 12) and the coupling engagement of the support bar 31 of the adjustable locking assembly 30 with the coupling groove 13 of the first connection member 10 (e.g., the first support riser 12);

That is, in the first embodiment of the present application, the second connection member 20 may also be used to be engaged with the first connection member 10, and the engagement of the second connection member 20 with the first connection member 10 may cooperate with the support rod 31 of the adjustable locking assembly 30 to achieve the engaged mounting of the second connection member 20 on the first connection member 10, that is, the second connection member 20 may be engaged with the engaged engagement of the first connection member 10 at the first support riser 12, and the engaged engagement of the support rod 31 of the adjustable locking assembly 30 with the engaged engagement of the first connection member 10 at the engaged groove 13, to be engaged with the first connection member 10. Compared with the case of only using the support rod 31 of the adjustable locking assembly 30 to achieve the hitching installation, the hitching cooperation of the second connection member 20 and the first connection member 10 is increased, so that the stability of the hitching installation can be improved, and the stability of the preassembly state of the second panel 60 can be improved.

Fig. 9 is a schematic view of a clamping space for installing an adjustment assembly in a first embodiment of the present application. Referring to fig. 9, illustratively, in a first embodiment of the present application, the support bar 31 of the adjustable locking assembly 30 may have opposite-facing limit-fit ends and movable-fit ends, the movable-fit ends of the support bar 31 being adapted to be movably fitted with the eccentric members 35, and the limit-fit ends of the support bar 31, and the eccentric members 35 movably connected to the movable-fit ends of the support bar 31 may cooperatively form limit-grip with respect to the first and second connection members 10 and 20 (e.g., the first and second support risers 12 and 22) in the panel-joining direction X when the adjustable locking assembly 30 is mounted to the first connection member 10 in a hitching manner.

Illustratively, in the first embodiment of the present application, the limit-fit end of the support rod 31 and the eccentric member 35 cooperatively achieve limit clamping, may have a clamping space dimension s_lmt in the panel splicing direction X, and the clamping space dimension s_lmt may be variable. Wherein, the minimum value of the variation range of the clamping space dimension s_lmt may be a reference dimension W0 in the panel splicing direction X, the "eccentricity" of the eccentric member 35 may refer to a radial dimension between a member profile of the eccentric member 35 on a projection plane perpendicular to the reference axis c_ref and the reference axis c_ref, which is parallel offset with respect to the reference axis c_ref, the maximum eccentricity distance Δr of the eccentric member 35 may be a difference between a maximum value r_max and a minimum value r_min of the radial dimension, and the maximum value of the variation range of the clamping space dimension s_lmt may be a sum of the reference dimension W0 and the maximum eccentricity distance Δr of the eccentric member 35 in the panel splicing direction X.

Illustratively, in the first embodiment of the present application, the interference fit end of the support rod 31 and the eccentric member 35 cooperatively provide interference grip that may be used to provide a retention force for the hitch mounting of the second coupling member 20 to the first coupling member 10. For example, the maximum value w0+Δr of the clip space dimension s_lmt of the limit clip may enable the limit clip to provide a retention force for the hitching installation of the second connection member 20 on the first connection member 10.

Illustratively, in the first embodiment of the present application, the clamping space dimension s_lmt of the spacing clamp in the panel splicing direction X may be reduced in response to the first eccentric rotation of the eccentric member 35, i.e., the clamping space dimension s_lmt may be reduced toward the minimum value W0, the dimension reduction amplitude of the clamping space dimension s_lmt in the panel splicing direction X may be determined by the actual eccentric distance of the eccentric member 35 in the panel splicing direction X, and the actual offset distance is greater than 0 and less than or equal to the maximum eccentric distance Δr. Since the actual eccentric distance of the eccentric member 35 in the panel splicing direction X is determined by the rotational phase of the eccentric member 35 during the first eccentric rotation, the size reduction width of the clamping space size s_lmt in the panel splicing direction X can be regarded as being determined by the rotational phase of the eccentric member 35 during the first eccentric rotation, and the adjustment result of the splice fit size by the first positional displacement of the second connecting member 20 near the first connecting member 10 can be correlated with the size reduction width of the clamping space size s_lmt. Thus, the adjustment result of the splice fitting size can be determined by controlling the rotational phase of the eccentric member 35 during the first eccentric rotation through the external locking operation.

Illustratively, in the first embodiment of the present application, the clamping space dimension s_lmt of the spacing clamp in the panel splicing direction X may also be increased in response to the second eccentric rotation of the eccentric member 35, i.e., the clamping space dimension s_lmt may be increased toward the maximum value w0+Δr, thereby, the second panel 60 may be allowed to resume the pre-assembled state described previously.

Illustratively, in the first embodiment of the present application, the limit fit end of the support rod 31 may be limit-fitted with the first connection member 10 (e.g., the first support riser 12) in the panel splicing direction X, the eccentric member 35 may be slidably abutted with the second connection member 20 (e.g., the second support riser 22) in the panel splicing direction X, and the limit fit end of the support rod 31 and the limit grip of the eccentric member 35 on the first connection member 10 and the second connection member 20 in the panel splicing direction X may be cooperatively realized by the limit fit end of the support rod 31 and the limit fit of the first connection member 10 (e.g., the first support riser 12) and the sliding abutment of the eccentric member 35 and the second connection member 20 (e.g., the second support riser 22).

In this case, both the first eccentric rotation of the eccentric member 35 in response to the external locking operation and the second eccentric rotation in response to the external unlocking operation may be supported by the movable fit end of the support rod 31, and since the support rod 31 is also fixed in position by the position-restricting fit of the position-restricting fit end with the first connection member 10 (e.g., the first support riser 12), the movable fit end of the support rod 31 may be a fixed support point for the first eccentric rotation and the second eccentric rotation of the eccentric member 35, and the reference axis c_ref described above may be located at the movable fit end of the support rod 31 as the fixed support point.

Thus, in a first embodiment of the present application, a first eccentric rotation of the eccentric member 35 may cause an offset of the eccentric member 35 proximate to the first connecting member 10 (e.g., the first support riser 12), an actual eccentric distance of the eccentric member 35 proximate to the first connecting member 10 (e.g., the first support riser 12) causes a corresponding size reduction of the clamping space dimension s_lmt, and based on a sliding abutment of the eccentric member 35 with the second connecting member 20 (e.g., the second support riser 22), a first eccentric rotation of the eccentric member 35 may cause the eccentric member 35 to push the second connecting member 20 through the support rod 31 to generate a first positional offset proximate to the first connecting member 10 in the panel stitching direction X to mount stitch the second panel 60 with the first panel 50 in the panel stitching direction X, and the first positional offset is utilized to adjust a mating dimension between the second panel 60 and the first panel 50 (e.g., between the first panel stitching edge 55 of the first panel 50 and the second panel stitching edge 65 of the second panel 60) in the panel stitching direction X.

Similarly, in a first embodiment of the present application, a second eccentric rotation of the eccentric member 35 may cause the eccentric member 35 to deflect away from the first connecting member 10 (e.g., the first support riser 12), the actual eccentric distance of the eccentric member 35 away from the first connecting member 10 (e.g., the first support riser 12) causes a corresponding increase in the clamping space dimension S_lmt, and based on the sliding abutment of the eccentric member 35 with the second connecting member 20 (e.g., the second support riser 22), the second eccentric rotation of the eccentric member 35 may cause the eccentric member 35 to release the abutment pressure against the second connecting member 20 (e.g., the second support riser 22) to allow the second connecting member 20 to deflect away from the second position of the first connecting member 10 in the panel splice direction X, thereby allowing the second panel 60 to resume the pre-assembled state described above.

Illustratively, in the first embodiment of the present application, the limit fit end of the support rod 31 may be in limit fit with the first support riser 12 of the first connection member 10 on a side of the first support riser 12 facing away from the second connection member 20. If the first connecting member 10 includes a pair of first supporting risers 12, the limit engaging end of the supporting rod 31 may be in limit engagement with the first supporting riser 12 at a side of the first supporting riser 12 relatively far from the second connecting member 20 facing away from the second connecting member 20.

Illustratively, in the first embodiment of the present application, the limit fit end of the support rod 31 may be provided with a limit nut 33 (e.g., any one of a wing nut, a knurled nut, and a quincuncial nut), for example, the limit fit end of the support rod 31 may have a first threaded section 311, and the limit nut 33 may be provided to the limit fit end by screw fit with the first threaded section 311, the limit nut 33 being located at a side of the first support riser 12 facing away from the second connection member 20, and the limit fit end of the support rod 31 achieving limit fit with the first connection member 10 in the panel splicing direction X by a limit abutment of the limit nut 33 with the first support riser 12 in the panel splicing direction X.

Illustratively, in the first embodiment of the present application, the position of the limit nut 33 on the side of the first support riser 12 facing away from the second connection member 20 can be made adjustable by the screw-fitting of the limit nut 33 with the first screw-thread section 311, and thus, the installation position of the limit-fitting end of the support rod 31 can be made adjustable, and thus, the reference dimension W0 (i.e., the minimum value) of the clamp space dimension s_lmt in the panel splicing direction X can be made adjustable. Since the adjustment result of the first positional deviation of the second connecting member 20 in the panel splicing direction X to the splice mating dimension near the first connecting member 10 is associated with the reference dimension W0 of the clamping space dimension s_lmt in addition to the actual deviation distance of the eccentric member 35, and the reference dimension W0 is associated with the mounting position of the limit nut 33 at the first screw section 311 (i.e., the mounting position of the limit mating end of the support rod 31), the mounting position of the limit nut 33 at the first screw section 311 (i.e., the mounting position of the limit mating end of the support rod 31) can be adjusted, so that the dimension range of the clamping space dimension s_lmt can be adjusted, thereby improving the adaptability of the mounting adjustment assembly to different adjustment range requirements.

Illustratively, in the first embodiment of the present application, the eccentric member 35 may slidably abut against the second support riser 22 of the second connection member 20 on a side of the second support riser 22 facing away from the first connection member 10, and the movable fit end of the support shaft 31 may pass through the riser insertion through hole 211 to be movably connected with the eccentric member 35 on a side of the second support riser 22 facing away from the first connection member 10.

Illustratively, in the first embodiment of the present application, a transition washer 36 may be further provided between the eccentric member 35 and the second support riser 22, and the movable-fit end of the support rod 31 may be movably fitted with the eccentric member 35 through the transition washer 36. Wherein the transition washer 36 may be abutted by the eccentric member 35 on a side of the second support riser 22 facing away from the first connection member 10, and wherein the transition washer 36 has a sliding engagement surface 360 facing away from the second support riser 22, the eccentric member 35 being slidably engaged with the sliding engagement surface 360.

Preferably, in the first embodiment of the present application, the hardness of the transition washer 36 may be lower than that of the eccentric member 35, further, the hardness of the transition washer 36 may also be lower than that of the second connection member 20 (e.g., the second support riser 22), for example, if at least one of the eccentric member 35 and the second connection member 20 is made of a metal material, the transition washer 36 may be made of a material having a hardness lower than that of the metal, such as a plastic or rubber material. The use of the low-hardness transition washer 36 can reduce wear of the eccentric member 35 due to direct hard contact with the second connection member 20 (e.g., the second support riser 22) on the one hand, so that wear of the second support riser 22 can be reduced to improve the service life of the second connection member 20, and on the other hand, the low-hardness transition washer 36 can be compressed between the eccentric member 35 and the second connection member 20 (e.g., the second support riser 22) by appropriate elastic compression deformation, e.g., the transition washer 36 can be compressed between the eccentric member 35 and the second connection member 20 (e.g., the second support riser 22), so that an anti-loosening constraint can be formed between the eccentric member 35 and the second connection member 20 (e.g., the second support riser 22).

Fig. 10 is a schematic view showing an assembled structure of an adjustable locking assembly for mounting an adjustment assembly in a first embodiment of the present application. Referring to fig. 10, in the first embodiment of the present application, the movable-fit end of the support rod 31 may be provided with a rotation pin 34, for example, the movable-fit end of the support rod 31 may have a second threaded section 312, the rotation pin 34 may have a radial screw hole 340, and the rotation pin 34 is provided at the movable-fit end of the support rod 31 through the threaded engagement of the second threaded section 312 with the radial screw hole 340. In this case, the movable fit end of the support rod 31 may be movably coupled with the eccentric member 35 through the rotation pin 34, for example, the eccentric member 35 may have the installation pin hole 353, and the rotation pin 34 may be rotatably inserted into the installation pin hole 353 to achieve the movable coupling of the movable fit end of the support rod 31 with the eccentric member 35. Thus, both the first eccentric rotation and the second eccentric rotation of the eccentric member 35 may be about the rotation pin 34 as a fulcrum (e.g., a fixed fulcrum), and the reference axis c_ref described above may be the axis of the rotation pin 34 as a fixed fulcrum, so that both the first eccentric rotation and the second eccentric rotation of the eccentric member 35 are eccentric with respect to the rotation pin 34.

Illustratively, in the first embodiment of the present application, the eccentric member 35 may include an operating handle 351, and an eccentric cam 352 fixedly connected to the operating handle 351. Wherein the eccentric shaft c_bias of the eccentric member 35 is located at the geometric center of the eccentric cam 352, the mounting pin hole 353 coaxial with the reference axis c_ref is located at the eccentric cam 352, and the mounting pin hole 353 is offset from the geometric center of the eccentric cam 352, whereby the eccentric cam 352 is eccentrically engaged with the rotation pin shaft 34. Moreover, the eccentric cam 352 may also slidingly abut the second connection member 20, e.g., the eccentric cam 352 may slidingly engage the sliding engagement surface 360 of the transition washer 36 and abut the transition washer 36 on a side of the second support riser 22 facing away from the first connection member 10, at which time the transition washer 36 may be less stiff than the eccentric cam 352 and the second connection member 20 (e.g., the second support riser 22) to avoid wear from direct hard contact of the eccentric cam 352 with the second connection member 20 (e.g., the second support riser 22), and may also form a release-preventing constraint between the eccentric cam 352 and the second connection member 20 (e.g., the second support riser 22).

Illustratively, in the first embodiment of the present application, the operating handle 351 is configured to swing in response to any one of the external locking operation and the external unlocking operation, and the eccentric cam 352 may perform the first eccentric rotation or the second eccentric rotation with respect to the rotation pin 34, respectively, following the swing of the operating handle 351 in response to the external locking operation or the external unlocking operation.

Illustratively, in the first embodiment of the present application, the first panel 50 and the second panel 60, which can support the splice installation, are deployed in an application scenario in a wall-mounted manner, for example, as shown in fig. 3 to 5, the mounting frame 53, in which the rear surface of the first panel 50 (e.g., the rear cover convex hull 51) is mounted, and the auxiliary bracket 63, in which the rear surface of the second panel 60 is mounted, can support the wall-mounted installation. In this case, it is generally desirable that the clearance space between the rear back surfaces of the first and second panels 50 and 60 and the wall surface in the panel thickness direction Z is as small as possible, for example, the space dimension of the clearance space in the panel thickness direction Z may be the smallest projection dimension of the rear cover convex hull 51 of the first panel 50 in the panel thickness direction Z, and in order to support the splice-mounted first and second panels 50 and 60 in a wall-mounted manner and to satisfy the deployment requirement that the clearance space between the rear back surfaces of the first and second panels 50 and 60 and the wall surface is as small as possible, the eccentric member 35 may be kept parallel to the first and second panels 50 and 60 during the period in which the first eccentric rotation occurs.

In this case, the rotation pin 34 may be perpendicular to the first and second panels 50 and 60, and the swing plane of the operation handle 351 and the rotation planes of the first and second eccentric rotations of the eccentric cam 35 are parallel to the first and second panels 50 and 60.

Fig. 12 is an exploded view of a mounting and adjusting assembly in a second embodiment of the present application. Referring to fig. 11 and 12, in the first embodiment of the present application, the installation adjusting assembly for achieving the splice installation may still include the first coupling member 10', the second coupling member 20', and the adjustable locking assembly 30' as in the first embodiment.

Fig. 14 is a schematic view showing a mounting state of a second connection member of the mounting adjustment assembly in the second embodiment of the present application. Referring to fig. 13 and 14, in the second embodiment of the present application, similarly to the first embodiment, the first connection member 10 'may be used to be fixedly installed at the rear surface of the first panel 50, and the second connection member 20' may be used to be fixedly installed at the rear surface of the second panel 60.

Fig. 15 is a schematic view showing the effect of the installation adjusting assembly in the second embodiment of the present application to achieve splice installation. Referring to fig. 15, in a second embodiment of the present application, the adjustable locking assembly 30 'may be configured as in the first embodiment to enable preassembly of the second panel 60 by pivotally mounting the second connecting member 20' to the first connecting member 10', and to enable adjustment of the panel mating dimension between the first panel 50 and the second panel 60 of the splice installation by actuating the second connecting member 20' to generate a first positional offset. That is, in the second embodiment of the present application, the adjustable locking assembly 30' may include the support bar 31' and the eccentric member 35' as in the first embodiment, and the eccentric member 35' may be movably coupled with the support bar 31 '.

Thus, the second embodiment of the present application can have substantially the same technical effects as the first embodiment. Moreover, in the second embodiment of the present application, the adjustable locking assembly 30 may also support the release of the splice installation as in the first embodiment.

Illustratively, in the second embodiment of the present application, the first coupling member 10 'may include a hooking groove 13' similar to the first embodiment, the support rod 31 'of the adjustable locking assembly 30' may be inserted into the second coupling member 20', and the adjustable locking assembly 30' may be slid into the hooking groove 13 'through the support rod 31' in a posture parallel to the panel splicing direction X, enabling the hooking installation of the second coupling member 20 'at the first coupling member 10'.

Fig. 16 is a schematic structural view of a first connection member of a mounting adjustment assembly in a second embodiment of the present application. Referring to fig. 16, in the second embodiment of the present application, the first connection member 10' may include a first fixing base plate 11' and a first support riser 12', as in the first embodiment, the first fixing base plate 11' may have a first fixing base plate mounting hole 110', and the hooking groove 13' may be located at the first support riser 12'.

Unlike the first embodiment, in the second embodiment of the present application, the support bar 31' of the adjustable locking assembly 30' may have a concave step 316 and a limit step 317, the concave step 316 may be engaged with the hooking recess 13', and the limit step 317 is located at a side of the first support riser 12' facing away from the second connection member 20', so that, when the concave step 316 is engaged with the hooking recess 13', the limit step 317 may apply an anti-releasing constraint to the support bar 31' at a side of the first support riser 12' facing away from the second connection member 20', thereby improving stability of the hooking installation of the second connection member 20' at the first connection member 10', and thus improving stability of the pre-assembled state of the second panel 60.

Unlike the first embodiment, in the second embodiment of the present application, the eccentric member 35 'may also assist the support rod 31' in the second embodiment to achieve the hitching installation of the second connection member 20 'at the first connection member 10'. Illustratively, in the second embodiment of the present application, the first connection member 10 'may have the positioning slot 17, and the slot depth direction of the positioning slot 17 may be parallel to the slotting direction of the hooking slot 13 (e.g., parallel to the panel height direction Y when the first connection member 10' is fixedly mounted to the vertically-horizontally-disposed first panel 50). For example, the first connection member 10 'may further include a mount 16 connected to the first fixing base plate 11', preferably, the mount 16 may be connected between the first fixing base plate 11 'and the first support riser 12', and the mount 16 may have a positioning slot 17. In this case, the eccentric member 35' may be rotatably inserted into the positioning slot 17 of the first coupling member 10', and the adjustable locking assembly 30 may be coupled to the second coupling member 20' inserted with the support rod 31' by using the coupling engagement of the support rod 31' with the coupling slot 13' and the rotational insertion of the eccentric member 35' with the positioning slot 17. Thus, compared to the case where the hooking installation is achieved only by the hooking cooperation of the support bar 31 'and the hooking groove 13', the stability of the hooking installation of the second connection member 20 can be improved, and further, the stability of the preassembly state of the second panel 60 can be improved.

Illustratively, in the second embodiment of the present application, if the first connection member 10 'includes the mounting seat 16 in order to provide the positioning slot 17, the first connection member 10' may be molded at one time through a molding process such as a mold molding process.

Fig. 17 is a schematic structural view of a second connection member of the installation adjusting assembly in the second embodiment of the present application. Referring to fig. 17, in the second embodiment of the present application, the second connection member 20' may include the second fixing base plate 21' and the second support riser 22' as in the first embodiment, and the second fixing base plate 21' may have the second fixing base plate mounting hole 210'.

Unlike the first embodiment, in the second embodiment of the present application, the second support riser 22 'may have a riser connection screw hole 223, i.e., the second support riser 22' replaces the riser insertion through hole 221 in the first embodiment with the riser connection screw hole 223. Also, in the second embodiment of the present application, the supporting rod 31' of the adjustable locking assembly 30' may be inserted into the riser connection screw hole 223 of the second supporting riser 22' and screw-engaged with the riser connection screw 223, for example, the supporting rod 31' may have a third external screw thread section 313, and the supporting rod 31' may screw-engaged with the riser connection screw 223 using the third external screw thread section 313. Thus, based on the threaded engagement of the support rod 31 'of the adjustable locking assembly 30' with the riser connection screw hole 223 of the second support riser 22', the support rod 31 of the adjustable locking assembly 30' can be inserted (e.g., fixed insertion that is fixed with a limit in the panel splicing direction X) into the second connection member 12 '(e.g., the second support riser 22').

Illustratively, in a second embodiment of the present application, the adjustable locking assembly 30 'may be preloaded onto the second connecting member 20' prior to the splice installation of the first panel 50 with the second panel 60. For example, the adjustable locking assembly 30' may be preloaded to the second connection member 20 by inserting the support bar 31' into the second connection member 20' (e.g., removably inserted into the second support riser 22 ') before the second connection member 20' is mounted in the hanging manner (i.e., before the second panel 60 is in the preloaded state described above).

Unlike the first embodiment, in the second embodiment of the present application, the support rod 31' of the adjustable locking assembly 30' may be fixedly inserted into the second connection member 12' (e.g., the second support riser 22 '), and thus, there may be no need to provide a limit spring 37 for limiting the free sliding of the support rod 31' as in the first embodiment.

Fig. 18 is a schematic view of a clamping space for installing an adjustment assembly in a second embodiment of the present application. Referring to fig. 18, illustratively, in the second embodiment of the present application, when the adjustable locking assembly 30 'is to mount the second connection member 20' to the first connection member 10', the limit fit end of the support bar 31' and the eccentric member 35 'movably connected to the movable fit end of the support bar 31' may cooperatively form a limit grip with respect to the first connection member 10 'and the second connection member 20' (e.g., the first support riser 12 'and the second support riser 22') in the panel splicing direction X, and the grip space size s_lmt of the limit grip may be adjusted between the reference size W0 as a minimum value and the maximum value w0+Δr.

Unlike the first embodiment, in the second embodiment of the present application, the eccentric member 35' may be rotatably inserted into the first connecting member 10' (e.g., the positioning slot 17), the limit fit end of the support rod 31' is limit-fitted into the second connecting member 20' (e.g., the second support riser 22 ') in the panel splicing direction X, and the limit fit end of the support rod 31' and the limit grip of the eccentric member 35 on the first connecting member 10 and the second connecting member 20 may be cooperatively implemented by the rotational insertion of the eccentric member 35' into the first connecting member 10' (e.g., the positioning slot 17) and the limit fit end of the support rod 31' into the second connecting member 20' (e.g., the second support riser 22 ').

In this case, both the first eccentric rotation of the eccentric member 35 'in response to the external locking operation and the second eccentric rotation in response to the external unlocking operation may be supported by the first connecting member 10' (e.g., the positioning socket 17), and the first connecting member 10 '(e.g., the positioning socket 17) may be a fixed support point for the first eccentric rotation and the second eccentric rotation of the eccentric member 35, and the reference axis c_ref described previously may be located at the first connecting member 10' (e.g., the positioning socket 17) as the fixed support point. For example, the reference axis c_ref may be a slot center axis of the positioning slot 17, and the first eccentric rotation and the second eccentric rotation of the eccentric member 35' are eccentric with respect to the slot center axis of the positioning slot 17.

Thus, in the second embodiment of the present application, the first eccentric rotation of the eccentric member 35 'in the positioning slot 17 can cause the limit fit end of the support rod 31' to be pulled close to the first connection member 10', thereby causing the clamping space dimension s_lmt to generate a dimension reduction corresponding to the offset distance of the eccentric member 35'. That is, a first eccentric rotation of the eccentric member 35 'in the positioning slot 17 may be such that the eccentric member 35' pulls the second connecting member 20 through the support rod 31 'to generate a first positional offset in the panel stitching direction X near the first connecting member 10' to mount and stitch the second panel 60 with the first panel 50 in the panel stitching direction X, and adjust a stitch fit dimension between the second panel 60 and the first panel 50 (e.g., between the first panel stitching edge 55 of the first panel 50 and the second panel stitching edge 65 of the second panel 60) in the panel stitching direction X using the first positional offset.

Similarly, in the second embodiment of the present application, the second eccentric rotation of the eccentric member 35 'in the positioning slot 17 can cause the limit fit end of the support rod 31' to be pushed away from the first connecting member 10', thereby causing the clamping space dimension s_lmt to generate a dimension increase corresponding to the offset distance of the eccentric member 35'. That is, the second eccentric rotation of the eccentric member 35' in the positioning slot 17 may cause the eccentric member 35' to push the second connection member 20' through the support rod 31' to shift a second position away from the first connection member 10' in the panel splicing direction X, thereby restoring the second panel 60 to the pre-assembled state described above.

Illustratively, in the second embodiment of the present application, the limit fit end of the support rod 31' may have the third external thread section 313 described above, and the limit fit end of the support rod 31' may be screw-fitted with the riser connection screw 223 by using the third external thread section 313, so that the limit fit end of the support rod 31' may be fixedly inserted into the second connection member 20' by screw-fitting the third external thread section 313 with the riser connection screw 223, and further, the limit fit with the second connection member 20' in the panel splicing direction X is realized by fixedly inserting the limit fit end of the support rod 31' into the second connection member 20 '.

Illustratively, in the second embodiment of the present application, since the eccentric member 35 'is rotatably inserted into the positioning slot 17 of the first connection member 10', and the positioning slot 17 communicates with the hooking groove 13', the movable-fit end of the support rod 31' may be movably fitted with the eccentric member 35 'rotatably inserted into the positioning slot 17 through the hooking groove 13' at a side of the first support riser 12 'facing away from the second connection member 20'.

Fig. 19 is a schematic view of the eccentric relationship of the adjustable locking assembly in a second embodiment of the present application. Fig. 20 is a schematic view showing an assembled structure of an adjustable locking assembly according to a second embodiment of the present application. Referring to fig. 19 and 20, illustratively, unlike the first embodiment, in the second embodiment of the present application, the eccentric member 35' may include a screw link 356 and a rotary lock cylinder 356 coaxially connected, for example, the screw link 356 and the rotary lock cylinder 356 are coaxially connected along a slot center axis of the positioning slot 17, the rotary lock cylinder 356 is rotatably inserted in the positioning slot 17, and the rotary lock cylinder 356 has an eccentric spiral guide 359. In this case, the component eccentric shaft c_bias of the eccentric component 35' may be located at the spiral center of the eccentric spiral guide 359, and the reference axis c_ref may be the slot center axis of the positioning slot 17, so that the spiral center of the eccentric spiral guide 359 is eccentrically disposed with respect to the slot center axis of the positioning slot 17.

Illustratively, in the second embodiment of the present application, the eccentric helical track 359 surrounds the barrel cavity of the rotary lock barrel 356, the movable mating end of the support rod 31 'is restrained within the barrel cavity of the rotary lock barrel 356 in the panel splicing direction X, and the eccentric helical track 359 is slidably mated with the movable mating end of the support rod 31'. For example, the movable mating end of the support rod 31 'may have a cambered end 315, the cambered end 315 may be further away from the second connecting member 20' than the concave step 316 and the limiting step 317 described above, the cambered end 315 is slidably engaged with the eccentric helical rail 359 in the barrel cavity of the rotary lock barrel 356, and the cambered end 315 may be circumferentially limited in the barrel cavity of the rotary lock barrel 356 by the eccentric helical rail 359.

Illustratively, in a second embodiment of the application, the eccentric member 35' may further include a bottom web 358, the bottom web 358 may be located at the bottom of the rotary lock cylinder 356 at the end remote from the screw rod 356, and the bottom web 358 may be attached to the inner edge of the eccentric screw guide 359 to increase the strength of the eccentric screw guide 359.

Illustratively, in the second embodiment of the present application, the screw link 356 is used to rotate the rotary lock cylinder 356 about the slot center axis of the positioning slot 17 in response to any one of an external locking operation and an external unlocking operation to effect the first eccentric rotation or the second eccentric rotation of the eccentric member 35', respectively.

Illustratively, in order to support the splice-mounted first and second panels 50, 60 in a wall-mounted arrangement and to meet the deployment requirement of as little as possible clearance space between the rear faces of the first and second panels 50, 60, in a second embodiment of the application, the eccentric member 35' may remain parallel to the first and second panels 50, 60 during the occurrence of the first eccentric rotation, as in the first embodiment. That is, the coaxially connected screw link 356 and rotary lock cylinder 356 are both constrained by the locating slot 17 to be parallel to the first panel 50 and the second panel 60.

In other embodiments of the present application, a multimedia device is also provided, which may include a first panel 50 and a second panel 60 mounted in a spliced manner using the mounting adjustment assembly described in the foregoing first embodiment or second embodiment.

In an exemplary installation adjusting assembly for the multimedia device, the first connecting member 10 may be fixedly mounted to the first panel 50 at the first panel splicing edge 55 of the first panel 50, and/or the second connecting member 20 may be fixedly mounted to the second panel 60 at the second panel splicing edge 65 of the second panel 60, so that the distance between the first connecting member 10 and the second connecting member 20 in the panel splicing direction X is smaller, and the installation adjusting assembly may be more intensively disposed at the splicing gap, thereby being beneficial to improving the adjustment accuracy of the splice fit size.

Illustratively, the first panel 50 and the second panel 60 of the multimedia device are of different panel types, e.g., the first panel 50 may comprise a display panel and/or the second panel 60 may comprise a handwriting panel, i.e., the multimedia device may be compatible with different types of panel combinations.

Illustratively, the first panel 50 and the second panel 60 of the multimedia device may be splice-mounted using at least two sets of mounting adjustment assemblies spaced apart in the panel height direction Y, and thus, uniformity of splice-fit dimensions of the splice-mounted in the panel height direction Y may be improved.

Illustratively, the first panel 50 of the multimedia device is respectively splice-mounted with a pair of second panels 60 on opposite sides in the panel splice direction X, i.e., a panel maximization configuration supporting the multimedia device.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the application.
