Therefore, accessories can be simplified, a system can be assembled rapidly and effectively without complex installation technology, and project construction management flow and technology in the aspect of construction of the current exhibition can be effectively simplified.

Fig. 1 shows a schematic perspective view of a rapid-assembly profile according to a first embodiment of the invention, and fig. 2 shows a schematic cross-sectional view of the profile shown in fig. 1. As shown in fig. 1 and 2, the profile 1 of the present embodiment is hollow and extends in the longitudinal direction thereof, has a Y-shaped cross section, and includes two branch portions 11 and 12 perpendicular to each other, and an extension portion 14 extending from a connecting portion 13 of the two branch portions in a direction away from the branch portions, and each of the two branch portions includes a first inner cavity 15 and a second inner cavity 16.

As shown in fig. 3 to 6, the profile 1 of the present embodiment can be fixed to the other profile 3 in a manner orthogonal to the other profile 3 by means of the fastener 4 provided in the first cavity 15 and the second cavity 16 of the profile 1 and locked to the groove C of the other profile 3. The groove C may be formed on at least one side of the profile 3 and extend along the length of the profile.

As an example of an application, fig. 7 shows a schematic structural diagram of a system assembled with the profile 1 of fig. 1. As shown in fig. 7, the present application example may include three kinds of profiles connected, namely, a profile 1 (a first profile 1), a second profile 2, and a third profile 3 of the present invention. The third profile 3 may have a groove C extending in the longitudinal direction thereof at least on one side, and the first profile 1 and the second profile 2 may each have at least one inner cavity extending in the longitudinal direction thereof, and the first profile 1 and/or the third profile 2 may be fixed to the third profile 3 so as to be orthogonal to the third profile 3 by a fastener provided in the inner cavity and locked to the groove C of the third profile 3. The fastener may be an existing tri-latch or similar structure.

Specifically, fig. 7 shows the assembled rectangular parallelepiped frame. Wherein the third profile 3 can be used as a bottom and top frame of the system and the first profile 1 and the second profile 2 can be used as side frames of the system. Preferably, in this embodiment, the first profile 1 can be used as an outer side frame and the second profile 2 can be used as an inner side frame. However, the present invention is not limited thereto, and the above-described various profiles 1 to 3 may be selectively used as needed. For example, the system of the present invention may be formed into a frame having various other three-dimensional shapes, not limited to a rectangular parallelepiped shape, or may be formed into a two-dimensional frame to be used only as a wall body, and may be provided with a single-layer frame composed of the first profile 1 and the third profile 3.

Further, as shown in fig. 3, in this application example, the third profile 3 may be a profile having a substantially T-shaped cross section as a whole, and may include a hollow main body portion 31 extending in the longitudinal direction thereof and two extension portions 32 connected thereto, and the grooves C may be formed in the extension portions 32, respectively.

Specifically, in the assembly, after cutting one end of each of the two third profiles 3 by 45 °, the two third profiles 3 are spliced together along the cut portion to form an assembly having a right angle. The invention does not need to fasten the two mutually spliced third sections 3, so that embedded parts such as internal corner brackets and the like do not need to be preassembled in the sections. Specifically, as shown in fig. 3, the main body 31 and the extension portions 32 at the joint of the two third profiles 3 are connected to each other to form right-angle portions, that is, first right-angle portions 33 on the outer side formed by a pair of extension portions 32, and second right-angle portions 34 on the inner side formed by the two main body portions 31.

The first section bar 1 is orthogonally arranged on the spliced third section bar 3 and is respectively connected with the two spliced third section bars 3. Specifically, the first profile 1 is placed vertically on the extension 32 of the third profile 3, outside the body 31 of the third profile 3 after splicing. Specifically, the first profile 1 is placed vertically on the extension 32 of the outer side of the two third profiles 3 in such a way that the right angles of the two mutually perpendicular branches 11, 12 of the first profile 1 cooperate with the above-mentioned second right angle portion 34, and the extension 14 of the first profile 1 extends along the splice line of the two third profiles 3. At this time, the first and second inner cavities 15 and 16 of the first profile 1 correspond to the grooves C of the outer sides of the two third profiles 3, respectively.

As shown in fig. 3 to 6, the fasteners 4 are inserted into the first and second lumens 15 and 16, respectively. The fastening members 4 inserted into the respective cavities are engaged with the corresponding grooves C, so that the first section bar 1 is orthogonally fixed to the two third section bars 3 after the splicing, and the first section bar and the third section bar can be fastened together without preassembling embedded parts such as internal corner brackets. In the prior art, if embedded parts are to be built in a complex structure, the requirement on flexibility of assembly and assembly sequence is limited, and the on-site installation progress is limited. The invention has the remarkable advantages that the structure of the profile is improved, the installation of the built-in embedded part is omitted, and the installation sequence and convenience of project construction are improved through the external structural part.

Specifically, one fastener 4 may be inserted into each of the cavities, or a plurality of fasteners 4 may be inserted into each of the cavities. The number of the fasteners can be set according to the requirement, and the size of each inner cavity can be designed according to the number, the layout and the like of the fasteners. In the present embodiment, as shown in fig. 5, the fastener 4 may be a three-click type fastener, which is a conventional device, and includes a main body 41, a lock tooth 42 protruding from a bottom end of the main body 41, and a locking portion 43 provided on the main body 41.

As shown in fig. 6, when the fastener 4 is inserted into the first and second cavities 15 and 16, the locking teeth 42 are exposed from the bottom ends of these cavities and snap into the grooves C of the third profile 3. Specifically, as shown in fig. 3, a through hole 7 is formed at a predetermined position of one side wall of each cavity, and the position of the through hole 7 may correspond to the position of the locking portion 43 of the fastener 4, so that the locking portion 43 may be exposed to the cavity, and the user may conveniently adjust to engage the locking teeth 42 with the grooves C.

From above, in the present application example, by inserting two tri-latches as the fastener 4 into the first inner cavity 15 and the second inner cavity 16 of the first profile 1, respectively, the locking teeth 42 of the fastener 4 are exposed from the bottom end of the first profile 1 and engaged with the groove C of the third profile 3, whereby the first profile 1 and the third profile 3 are combined by the two locking teeth 42 to form the assembly. All the profiles are assembled to form the system of the embodiment, and the installation process is convenient and quick. And utilize the right angle structure of first section bar 1, can make the 45 concatenation angles of two third section bars 3 under the prerequisite that no built-in angle sign indicating number and screw nut fasten, overall structure is firm, is difficult for broken outward, greatly increased assembly speed, reduced the assembly degree of difficulty.

As also shown in fig. 1 and 2, the profile 1 of the present invention may comprise a first groove a at the free ends of the two branches 11, 12, respectively, for the mounting of various types of accessories, such as stiffeners and the like, as required. The first grooves may be open toward the bifurcation direction, respectively. As shown in fig. 8 and 9, a peripheral diagonal reinforcement 51 connected to the first profile 1 and the third profile 3 may be added between the two. Both ends of the reinforcing member 51 may be fixed to the groove a of the first profile 1 and the groove C of the third profile 3, respectively, by fasteners. As shown in fig. 10, a transverse reinforcement 53 for the peripheral device connected to the two first profiles 1 can also be added between the two opposing profiles. The reinforcement 53 can be fastened between the grooves a of the two first profiles 1 facing each other by means of fasteners.

In addition, the profile 1 according to the invention can also comprise a second groove B at the free end of the extension 14 for the installation of various accessories, such as wall surfaces and the like, as desired. The slot may be formed as a trident shaped slot. Fig. 11 shows a schematic view of the construction of the assembled wall surface 6 on the system of fig. 7. The wall surface 6 may be made of flexible material with pictures or text logos printed thereon. The picture wall facade of the system can be formed by clamping the wall surface 6 made of flexible material in the second groove B of the first profile, the groove D at the tip of the extension 32 of the third profile 3, respectively. For example, the wall surface 6 may be formed by sewing a rubber strip or the like to the edge of the flexible material, and attaching the rubber strip to the frame by engaging the rubber strip in the groove. After the flexible material covers, the framework of the system can be hidden, so that the double-sided borderless card cloth wall body can be realized, and a more efficient, attractive, safe and quick display form is provided. The inner space surrounded by the four sides of the section bar can be used for temporary space use of exhibition, such as meeting, storage space and the like according to the difference of the length and the size of the section bar.

Specifically, in the present embodiment, the extension portion 14 is formed in a hollow structure and includes an inner cavity as in the above-described branch portions 11 and 12, but the present invention is not limited thereto, and the extension portion 14 may be formed in a plate-like structure extending from the connection portion 13 in a direction away from the branch portions 11 and 12, as in the second embodiment shown in fig. 12.

In addition, fig. 13 shows a schematic structural view of a further system assembled with the profile shown in fig. 1. In the application example shown in fig. 13, it is assembled from only the profile 1 according to the invention. As shown in fig. 13, both ends of each of the profiles 1 are cut obliquely and then spliced.

In particular, fig. 14 to 20 show schematic views of a cutting process for assembling the system shown in fig. 13. Fig. 14 to 17 are schematic views of the profile 1 being cut into a first configuration, and fig. 18 to 20 are schematic views of the profile 1 being further cut into a second configuration. Fig. 14 to 16 are front, left and top views respectively showing the first branch portion 11 of the profile 1 as a horizontal reference and the second branch portion 12 of the profile 1 as a horizontal reference and fig. 18 to 20 are front, left and top views respectively showing the second branch portion 11 of the profile 1 as a horizontal reference and the second branch portion of the profile 8. In each figure, the Y axis is the length extending direction of the profile 1, the X axis is the direction orthogonal to the Y axis in the horizontal direction, and the Z axis is the vertical direction.

As shown in fig. 14 to 17, the profile 1 is placed on the horizontal backrest 8 with the X axis and the Y axis as horizontal planes, and one short side (i.e., the first bifurcation 11) of the profile is placed on the horizontal backrest with the long side (i.e., the extension 14) forming an angle of 45 degrees with the horizontal plane. The initial state of the saw blade is a first tangent plane I, which is perpendicular to the horizontal plane, in particular parallel to the X-axis, the Z-axis, and orthogonal to the Y-axis (i.e. the direction corresponding to the cross-section of the profile 1). The saw blade rotates along the X axis anticlockwise by 45 degrees, which is a second section II of the saw blade. The entire profile 1 is cut vertically in the Z-axis direction with a second section II. A first form of the cut profile I is obtained (as shown in fig. 21).

Subsequently, the other short side (i.e., the second split portion 12) of the profile 1 cut into the first form is set as a reference plane parallel to the horizontal plane. As shown in fig. 18 to 20, the other short side (i.e., the second bifurcation 12) of the profile I is placed on the horizontal backrest 8 with the X axis and the Y axis as horizontal planes, and the long side (i.e., the extension 14) forms an angle of 45 degrees with the horizontal plane. The initial state of the saw blade is the same as the above-mentioned first cutting plane I, which is perpendicular to the horizontal plane. The saw blade rotates 45 degrees clockwise along the X axis and is a third section III of the saw blade. The profile is cut vertically in the Z-axis direction with a third section III, which at the same time intersects the axis S of the beveled section of the profile 1 of the first form after cutting. As shown in fig. 21, this axis S is defined as the line connecting the perpendicular intersection of the two branches in the cut surface of the first form of the profile 1 to the midpoint of the second groove B. The second form of the profile 1 is obtained after the cutting (as shown in figure 22). That is, a part of the second split portion and the extension portion is obliquely cut off in the current cutting.

The second form of the profile 1 is the finished product after cutting for subsequent assembly. As shown in fig. 22, after cutting, the two bifurcation portions each have a 45 degree angle of inclination, and the extension portion also has a 45 degree angle of inclination with respect to the axis S. Subsequently, the cut profile 1 of the second form is assembled, and the profiles can be connected by fasteners, resulting in the frame shown in fig. 10.

The profile 1 of the invention has two mutually perpendicular bifurcation parts, so the bifurcation parts can be directly leaned against the horizontal backer to conveniently cut, in particular to cut obliquely, no complex clamp is required to be additionally arranged, the cutting process can be simplified, and the cost can be reduced.

The profile of the invention can be suitable for various application occasions. Including but not limited to display cases, display posts, display walls for exhibitions, partition walls for display rooms, borderless light boxes for display stands, partitions for negotiating areas, ceiling structures for display stands, hanging signs for exhibitions, and the like.

In conclusion, the novel design structure of the profile is fully utilized, and the most common assembly locking piece in the market is combined, so that the original embedded piece is reduced, and the assembly steps and the technology are simplified. The method can greatly reduce the field operation time and working procedures of the exhibition, and the optimized assembly profile not only reduces the number of people working simultaneously on the field, but also greatly reduces the potential risk of the field caused by the original complex assembly technology and working procedures. The novel design structure of the profile has the maximized structural strength of the aluminum profile, the height of the assembled wall body can reach 6 meters at maximum, and the length of the wall body can reach 6 meters at maximum. To achieve this size, conventional usage techniques must use steel wood structures. Resulting in a significant increase in both the assembly process and the weight of the material. In addition, the repeated use rate of the integral accessory can reach 100%, the phenomenon of waste of a large amount of resources originally generated in the construction process of the exhibition is reduced, and the environment-friendly sustainable ecological idea is truly realized.

The present invention may be embodied in several forms without departing from the spirit of the essential characteristics thereof, and the embodiments of the invention are therefore intended to be illustrative and not restrictive, since the scope of the invention is defined by the claims rather than by the description, and all changes that come within the meaning and range of equivalency of the claims, or range of equivalents thereof, are therefore intended to be embraced therein.
