Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the present application, the directional term "axially upward" refers to the direction of arrow a in fig. 1, and the directional term "axially downward" refers to the direction of arrow B in fig. 1.

Fig. 1 schematically shows a cross-sectional view of the structure of a connection mechanism 1 according to one embodiment of the application. Fig. 2 schematically shows an exploded view of the fixed end assembly 100. Fig. 11 schematically shows a cross-sectional view of the fixed end assembly 100.

As shown in fig. 1,2 and 11, the connection mechanism 1 includes: the fixed end assembly 100 and the movable end assembly 200, the movable end assembly 200 is detachably connected to the fixed end assembly 100. The fixed end assembly 100 includes a guide cylinder 101 penetrating axially, a push type lockbar device 300 movably disposed in the guide cylinder 101, a first gear 102 disposed at an axial end of the push type lockbar device 300, and a second gear 103 axially disposed outside the guide cylinder 101 and engaged with the first gear 102. The second gear 103 is axially movable and urges the first gear 102 and the push type locklever 300 to axially move, the first gear 102 having a first position and a second position in the axial direction, the first position being higher than the second position. The movable end assembly 200 includes a base 201 and a linkage 202 coupled to the base 201. The base 201 contacts the second gear 103 to push the second gear 103 to move axially. The connecting rod 202 passes through the center hole of the first gear 102 and the center hole of the second gear 103 and extends into the push type locklever 300. In the first state, the first gear 102 moves axially and rotates to the first position, the push type lockbar 300 releases the link 202, and in the second state, the first gear 102 moves axially and rotates to the second position, the link 202 is locked by the push type lockbar 300.

Fig. 4 and 5 show the structure of the guide cylinder 101, and fig. 6 schematically shows the structure of the first gear 102. As shown in fig. 4, 5 and 6, a stopper rib 106 is provided on the inner wall of the guide cylinder 101. The first gear 102 is axially configured with a first detent structure and a second detent structure that selectively engage with the limit rib 106, the first detent structure being higher than the second detent structure. In the first state, the limit rib 106 is engaged with the first detent structure; in the second state, the limit rib is engaged with the second detent structure. In use, the engagement of the stop rib 106 with the first gear 102 will be described in detail below.

In use of such a connection mechanism 1, the fixed end assembly 100 may be mounted on a foundation, such as a ceiling. A device to be assembled, such as a lamp head 401 (shown in fig. 3), is mounted on the base 201 of the movable end assembly 200. The movable end assembly 200 is mounted on the fixed end assembly 100, and the link 202 is inserted through the first gear 102 and the second gear 103 of the fixed end assembly 100 and into the push-type lockrod maker 300, with the base 201 in contact with the second gear 103. The movable end assembly 200 is pushed axially upward so that the base 201 pushes the second gear 103 to axially move upward, thereby axially moving the first gear 102 and rotating the second gear to lock the connecting rod 202 by the push type locking lever 300, thereby completing the installation of the device to be assembled. When the component to be assembled is disassembled, the movable end assembly 200 is pushed upwards axially, so that the base 201 pushes the second gear 103 to move upwards axially, the first gear 102 moves axially and rotates to the first position, and the pressing type lock rod device 300 releases the connecting rod 202, so that the component to be assembled can be disassembled. Thus, during use, the movable end assembly 200 is only pushed axially to disassemble and assemble the device to be assembled, circumferential force is not required to be applied, and the operation is not required to be performed in the lateral direction of the fixed end assembly 100, so that the operation of a user is greatly facilitated. For the lamp, a lateral installation space is not needed, so that a user can install the lamp conveniently.

Fig. 3 schematically implements a luminaire 4 according to an embodiment of the application. As shown in fig. 3, lamp 400 includes a lamp head 401 and a connection mechanism 1 as described above, lamp head 401 being fixedly connected to base 201 of movable end assembly 200. The lamp 4 further comprises a bracket 402, and the connection mechanism 1 is fixedly mounted on the bracket 402.

In one embodiment, the stent 402 may have a plurality of struts, four as shown in FIG. 3. Thus, four lightheads 401 may be mounted on one bracket 402. Of course, the stent 402 may have more or fewer struts. The shape of the lamp base 401 may also vary. And will not be described in detail here.

In the particular embodiment shown in fig. 6, the first gear 102 includes a first cylindrical body 110 that extends axially therethrough. The first cylindrical body 110 has inner teeth 113 at a first axial end portion thereof, which mesh with the teeth 112 of the second gear 103. The outer gear teeth 115 are formed to protrude radially outward on the circumferential outer surface of the first cylindrical body 110, and the valleys 116 of the outer gear teeth 115 form a first click structure. The second detent structure is a through slot 117 extending axially through the outer gear tooth 115. Thus, when the coupling mechanism 1 is in use, the first gear 102 can be brought into its first position when the limit rib 106 engages with the valley 116 of the outer gear tooth 115. When the limit rib 106 engages with the through groove 117, the first gear 102 moves axially downward under the guide of the limit rib 106, so that the first gear 102 is in its second position.

In order to prevent the first gear 102 from coming out of the guide cylinder 101, a first boss 111 extending radially outward is provided at the second axial end of the first cylindrical body 110, and a radially inward extending shoulder 114 engaging with the first boss 111 is formed on the inner wall of the guide cylinder 101. When the first gear 102 is in its first position, the first boss 111 is separated from the shoulder 114; when the first gear 102 is in its second position, the first boss 111 engages the shoulder 114, thereby preventing the first gear 102 from backing out of the guide cylinder 101. It will be appreciated that in this case, the through slot 117 extends through the first boss 111 along the outer surface of the first cylindrical body 110, and the first detent structure (or valley 116) is between the inner gear tooth 113 and the first boss 111.

In order to allow the first gear 102 to be continuously switched in a rotating manner between its first and second positions, the inner gear teeth 113 are formed with circumferentially spaced peaks 171 and valleys 172, and the second gear 103 is formed with circumferentially spaced peaks 173 and valleys 174. In the first and second states, the peaks 173 of the second gear 103 are in contact with the sloped connection areas 120 between the peaks and valleys of the inner gear teeth 113. Specifically, for example, in an initial state, the first gear 102 is in its first position; the lobe 173 of the second gear 103 contacts the beveled connection region 120 of the inner gear tooth 113; the spacing rib 106 engages the first engagement structure 116. When the second gear 103 pushes the first gear 102 axially upward, the stopper rib 106 cooperates with the outer gear teeth 115 so that the first gear 102 moves axially upward, and the first gear 102 receives a circumferential force. When the outer gear teeth 115 are moved to be completely disengaged from the limit ribs 106, the first gear 102 is no longer constrained by the limit ribs 106, and the first gear 102 rotates under the action of the circumferential force so that the limit ribs 106 gradually switch to correspond to the through grooves 117. Due to the meshing relationship of the first gear 102 (or inner gear 113) with the second gear 103, the first gear 102 moves axially downward during rotation. After the limit rib 106 engages the through groove 117, the first gear 102 is no longer rotated; moving the second gear 103 axially downwards, the first gear 102 will also move axially downwards under the guiding action of the limit rib 106 and will eventually be in its second position. In the case where the initial state is that the first gear 102 is in its second position, the movement processes of the first gear 102 and the second gear 103 are almost the same as such, and will not be described here again. Thereby, a continuous switching of the first gear 102 between its first and second positions is achieved, thereby facilitating the use of the connection mechanism 1.

In one embodiment, a first spring 130 is disposed within the guide cylinder 101, with a first end of the first spring 130 coupled to the first gear 102, specifically, to the first cylindrical body 110 of the first gear 102 (e.g., coupled to the first boss 111 of the first cylindrical body 110), and a second end secured within the guide cylinder 101. During the axially upward movement of the first gear 102, the first spring 130 is compressed to facilitate subsequent axially downward movement of the first gear 102 driven by the first spring 130. In addition, the first spring 130 also limits the axial upward movement of the first gear 102 to ensure that the first gear 102 moves within a proper axial range.

Fig. 7 schematically shows the structure of the second gear 103. As shown in fig. 7, the second gear 103 includes a second cylindrical body 140 penetrating axially, a first end of the second cylindrical body 140 having an annular flange 141 extending radially inward, and gear teeth 142 of the second gear 103 formed on the flange 141. The second end of the second cylindrical body 140 has an inner diameter larger than the outer diameter of the guide cylinder 101 such that the second cylindrical body 140 is movably sleeved outside the guide cylinder 101. In the assembled state, the second cylindrical body 140 is fitted over the outside of the guide cylinder 101, and thereby ensures that the teeth 142 of the second gear 103 and the inner teeth 113 of the first gear 102 mesh with each other when the first gear 102 and the second gear 103 axially move, reducing the probability of failure of the connection mechanism 1.

The fixed end assembly 100 further includes a housing 150 extending axially therethrough, and the guide cylinder 101 is received within the housing 150 (as shown in fig. 2).

Fig. 8 schematically shows the structure of the housing 150. As shown in fig. 8, at a first end of the housing 150, there is an annular carrier plate 151 extending radially inward, and at a second end of the second cylindrical body 140, there is a second boss 143 extending radially outward. The second boss 143 can be carried on the annular carrier plate 151 such that the second cylindrical body 140 can move axially through the central hole 152 of the annular carrier plate 151. As shown in fig. 2, the housing 150 combines the first gear 102, the second gear 103, the guide cylinder 101, and the push type lockbar 300 as a whole so that the fixed end assembly 100 is formed as a single body, which can easily mount the fixed end assembly 100 to a foundation such as a ceiling. In addition, the cooperation of the second boss 143 with the annular carrier plate 151 allows a portion of the second cylindrical body 140 of the second gear 130 to be located outside of the housing 150, which may facilitate the movable end assembly 200 (or the base 201) to push the second gear 130 axially upward.

In addition, first guide grooves 153 extending in the axial direction are formed on the circumferential inner surface 155 of the annular carrier plate 151, and first guide ribs 144 extending in the axial direction are formed on the outer surface of the second cylindrical body 140. The first guide rib 144 is axially movably inserted into the first guide groove 153 such that the second gear 130 is moved only in the axial direction without being rotated by the first guide rib 144 and the first guide groove 153. In a specific embodiment, the number of the first guide ribs 144 is four and is uniformly distributed in the circumferential direction, and the first guide grooves 153 are distributed corresponding to the first guide ribs 144.

In another embodiment, as shown in fig. 9, the base 201 includes a third cylinder 210 and a bottom plate 211 closing one end opening of the third cylinder 210, the third cylinder 210 has second guide ribs 203 extending in an axial direction on an inner surface thereof, and the housing 150 has second guide grooves 156 on an outer surface thereof to be engaged with the second guide ribs 203. In this way, the base 201 and the housing 150 can be conveniently coupled together with the second guide groove 156 and the second guide rib 203, thereby realizing the assembly of the movable end assembly 200 and the fixed end assembly 100. It will be appreciated that the second guide groove 156 terminates in a central region of the circumferential surface of the housing 150, i.e. the second guide groove 156 is non-axially through, so that the seat 201 can be fitted with the housing 150. In the assembled state, the end of the second gear 103 that is outside the housing 150 is in contact with the bottom plate 211. In addition, the base plate 211 may also be used in connection with the lamp head 401.

Fig. 10 schematically shows the structure of the push type locklever apparatus 300. As shown in fig. 2 and 10, the push-type lockbar actuator 300 includes a housing 301 having an interior cavity 302 extending axially therethrough. A first opening 304 communicating with the inner cavity 302 is provided at a first axial end of the outer sheath 301, the inner diameter of the inner cavity 302 gradually decreasing toward the first opening 304. The push-type lockbar latch 300 also includes a collar 305. A first portion 311 of collar 305 is axially movably disposed within interior cavity 302 and a second portion 310 is disposed outside of outer sleeve 301 and extends through first opening 304 into interior cavity 302 to connect with first portion 311. The side wall of the first portion 311 has a through hole 306, and a ball 307 is mounted in the through hole 306. The first gear 102 is disposed at an axial end of the second portion 310, the rod 202 extends into a first portion 311 of the collar 305, and the collar 305 is capable of sliding in the axial direction of the rod 202 while the ball 307 moves along the wall of the cavity 302. In the first state, the first gear 102 is in the first position, the ball 307 is clear of the link 202, so that the push type locklever 300 releases the link 202; in the second state, the first gear 102 is in the second position, and the ball 307 presses the link 202, so that the link 202 is locked by the push type locklever 300.

The push type locking bar 300 is used as follows. For example, the first portion 311 of the collar 305 is adjacent to the first opening 304, and the ball 307 is adjacent to the first opening 304 and presses the connecting rod 202 to an initial state. In the initial state, a portion of the ball 307 protrudes from the through hole 306 and presses the link 202, so that the movable end assembly 200 is stably coupled together with respect to the fixed end assembly 100. In one embodiment, in order to enable the beads 307 to more stably compress the connecting rod 202, the number of the beads 307 is three and uniformly distributed in the circumferential direction. Of course, more beads 307 may be provided in the circumferential direction, and will not be described here.

Upon removal of the movable end assembly 200, the movable end assembly 200 is pushed axially upward, causing the second gear 103, the first gear 102, and the collar 305 to move axially upward and the first gear 102 to be in its first position (the specific procedure is described above). In this process, the first portion 311 of the collar 305 moves away from the first opening 304 in the interior cavity 302 and the beads 307 move along the wall of the interior cavity 302 and away from the first opening 304 as the first portion 311 of the collar 305 moves. Since the inner diameter of the inner cavity 302 gradually expands in a direction away from the first opening 304, the ball 307 moves along the wall surface of the inner cavity 302 and away from the first opening 304, so that it no longer presses the connecting rod 202. Thus, the push type lockbar device 300 releases the link 202, so that the movable end assembly 200 can be easily detached from the fixed end assembly 100.

Upon installation of the movable end assembly 200, the connecting rod 202 is inserted through the first and second gears 102, 103 of the fixed end assembly 100 and into the push-down lock lever 300, pushing the movable end assembly 200 axially upward, causing the second gear 103, the first gear 102, and the collar 305 to move axially upward and the first gear 102 to be in its second position (the specific procedure being as described above). During this process, the first portion 311 of the collar 305 moves into the cavity 302 to the first opening 304, and the ball 307 moves along the wall of the cavity 302 and into the first opening 304 as the first portion 311 of the collar 305 moves, thereby compressing the connecting rod 202. Thus, the push type locking lever 300 locks the link 202, thereby conveniently and stably mounting the movable end assembly 200 to the fixed end assembly 100.

In a particular embodiment, as shown in fig. 10, the circumferential outer surface of the first portion 311 of the collar 305 forms a truncated cone with the small end of the truncated cone facing the first opening 304. The larger end of the truncated cone has a diameter greater than the diameter of the first opening 304 so that the collar 305 is prevented from accidentally falling out of the cavity 302. In other embodiments, collar 305 may have other shapes, such as having a cylindrical barrel and a radially outwardly extending shoulder, which will not be described in detail herein.

A second spring 313 is disposed in the interior cavity 302, a first end of the second spring 313 compressing the first portion 311 of the collar 305 and a second end of the second spring 313 being secured in the interior cavity 302. In this way, during axial movement of collar 305, second spring 313 may be compressed or released to assist in movement of collar 305.

In addition, a plug 315 is provided in the inner cavity 302 at a side remote from the first opening 304, and a second end of the second spring 313 is fixed to the plug 315. In this way, the degree of compression of the second spring 311 can be adjusted by adjusting the position of the plug 315 within the interior cavity 302 to facilitate axial movement of the collar 305. In one embodiment, the plug 315 is threadably coupled to the lumen 302 to facilitate adjusting the position of the plug 315.

When the connection structure 1 is used for mounting the lamp 4, the first conductive member 160 is disposed at the circumferential outer portion of the guide cylinder 101, and the second conductive member 220 (as shown in fig. 2 and 9) electrically contacting the first conductive member 160 is disposed on the base 201 of the movable end assembly 200, and the second conductive member 220 is electrically connected to the base 401. The number of the first conductive members 160 may be plural, for example, four, and uniformly distributed in the circumferential direction. The number and arrangement of the second conductive members 220 correspond to those of the first conductive members 160. In this way, electrical connection of lamp 4 is also completed at the same time as assembling lamp head 401, movable end assembly 200, and fixed end assembly 100 together, without separate wiring, which facilitates assembly of lamp 4.
