Description

Technical Field

[0001] This utility model relates to the field of light box technology, and in particular to a quick-assembly folding display rack and its light box. Background Technology

[0002] Light boxes are a common type of display and advertising equipment. Their core feature is that they use internal light sources to evenly illuminate the surface image, thereby achieving a high level of visual appeal. They are also flexible in various occasions, easy to install and maintain, and environmentally friendly and energy-saving. Therefore, light boxes are widely used in the commercial retail industry, outdoor advertising industry, catering industry, display and event occasions, and public spaces.

[0003] Existing light boxes mainly consist of folding display stands and display canvases. These are typically packaged and stored separately. The display stand itself needs to be disassembled into multiple parts for storage, while the display canvas needs to be rolled up and stored separately. This multi-part disassembly design increases the number of parts to carry, making it easy to get confused and cause omissions or mistakes, which inconveniences on-site setup. Summary of the Invention

[0004] The technical problem this utility model aims to solve is as follows: In order to address the issue that existing light boxes mainly consist of folding display racks and display canvases, which are usually packaged and stored separately, the display rack itself needs to be disassembled into multiple parts for storage, and the display canvas needs to be rolled up and stored separately, resulting in an increased number of parts to carry due to the multi-part disassembly design, which is easy to confuse and cause omissions or wrong carrying, causing inconvenience to on-site exhibition setup, this utility model provides a method for quickly assembling a folding display rack and its light box.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick-assembly folding display rack, including a frame formed by a top profile, two side profiles on both sides and a bottom profile, wherein the side profiles include at least two hinged to each other on the folding uprights; The two ends of the side profiles are hinged to the top and bottom profiles, respectively. Locking mechanisms are provided at the hinge points between the top and side profiles, and between the bottom and side profiles. These locking mechanisms control the connection between one end of the bottom and side profiles at adjacent hinge points, and between the other end of the bottom and side profiles, to lock when unfolded or unlock when folded. Compared to existing technologies, this solution, by providing locking mechanisms at the hinge points between the two ends of the side profiles on both sides and between the top and bottom profiles, and controlling the connection between the bottom and side profiles at these hinge points to lock when unfolded or unlock when folded, allows the entire frame to be unfolded and folded without disassembly. This significantly reduces the number of disassembled parts, greatly reduces confusion and the occurrence of omissions or incorrect items, and facilitates on-site setup.

[0006] To implement the locking mechanism, in some preferred embodiments, the locking mechanism includes a locking pin and a preload spring, wherein the locking pin is slidably disposed on one of the top profile and the side profile at the hinge, and on one of the bottom profile and the side profile at the hinge; Locking holes matching the locking pins are provided on one of the top and side profiles at the hinge, and on the other of the bottom and side profiles at the hinge. The locking pins are disposed within the locking holes, and the preload spring is used to preload the locking pins and ensure that they remain within the locking holes when locked. The locking pins, preload springs, and locking holes work together to achieve locking and unlocking of the hinges on the frame.

[0007] To enable the locking pin to slide on the frame, in some preferred embodiments, a sliding hole is provided on one of the top and side profiles at the hinge, and on one of the bottom and side profiles at the hinge. One end of the locking pin is slidably disposed within the sliding hole. The locking pin is respectively provided with a first limiting mechanism and a second limiting mechanism. The sliding hole is located between the first and second limiting mechanisms. The first and second limiting mechanisms cooperate to limit the sliding range of the locking pin. A preload spring is disposed between the first limiting mechanism and the sliding hole. The sliding hole is provided on the corresponding top, side, or bottom profile on the frame to enable the locking pin to slide within the sliding hole.

[0008] In order to facilitate the sliding of the locking pin in the sliding hole, in some preferred embodiments, the locking pin is a bolt, and the second limiting mechanism is a head disposed at one end of the bolt and located at one end of the sliding hole; The first limiting mechanism is a nut, and the bolt and the nut are threadedly connected to each other. The preload spring is a cylindrical spring, which is sleeved on the locking pin. One end of the preload spring abuts against the other end of the sliding hole, and the other end of the preload spring abuts against the nut. By using a bolt as the locking pin, the threads on the bolt are in the sliding hole. The threads on the bolt reduce the contact area with the sliding hole, thereby reducing the friction between the locking pin and the sliding hole, facilitating the sliding of the locking pin within the sliding hole.

[0009] In some preferred embodiments, an outwardly protruding latch is provided on one of the top profile and the side profile at the hinge, and on the other of the bottom profile and the side profile at the hinge, and the locking hole is provided on the latch.

[0010] In some preferred embodiments, the end of the locking tongue away from the locking pin is an arc surface, and the cross-sectional area gradually increases from the outside to the inside.

[0011] To better lock the hinge at the frame, in some preferred embodiments, a locking groove matching the locking tongue is provided on one of the top profile and side profile at the hinge, and on one of the bottom profile and side profile at the hinge. A through hole is provided at one end of the locking groove near the sliding hole. The through hole communicates with the locking groove and is coaxial with the sliding hole. One end of the locking pin passes through the through hole and is located in the locking groove, and one end of the locking tongue is located in the locking groove.

[0012] To facilitate control of the locking pin, in some preferred embodiments, the locking pin is provided with a pull ring.

[0013] In some preferred embodiments, the top profile includes at least two crossbars hinged to each other at the folded upper crossbar, and the bottom profile includes at least two crossbars hinged to each other at the folded lower crossbar.

[0014] A lightbox equipped with a quick-assembly folding display rack as described above.

[0015] The beneficial effects of this utility model are as follows: When using the quick-assembly folding display rack and its lightbox, locking mechanisms are set at the hinge points between the two ends of the side profiles on both sides and the top and bottom profiles, respectively. These locking mechanisms control the bottom and side profiles at the hinge points to lock when unfolded or unlock when folded. This allows the entire frame to be unfolded and folded without disassembly, greatly reducing the number of disassembled parts, significantly reducing confusion and the occurrence of omissions or mis-carrying, and facilitating on-site setup. This avoids the problems of existing lightboxes, which mainly consist of a folding display rack and a display canvas. The folding display rack and display canvas are usually packaged and stored separately. The display rack itself needs to be disassembled into multiple parts for storage, and the display canvas needs to be rolled up and stored separately. This multi-part disassembly design leads to an increased number of parts to carry, making it easy to get confused and cause omissions or mis-carrying, which brings inconvenience to on-site setup.

Detailed Implementation

[0019] Example 1, such as Figure 1-13 As shown, a quick-assembly folding display rack includes a frame formed by a top profile 1, two side profiles 2 on both sides, and a bottom profile 3. In this embodiment, the side profiles 2 include two folding uprights 301 that are hinged to each other. Of course, in addition to two folding uprights 301 that are hinged to each other, there can also be three, four, or more folding uprights 301 that are hinged to each other in sequence. The folding uprights 301 at the top and bottom ends of one side profile 2 are respectively hinged to one end of the top profile 1 and one end of the bottom profile 3. The folding uprights 301 at the top and bottom ends of the other side profile 2 are respectively hinged to the other end of the top profile 1 and the other end of the bottom profile 3. Locking mechanisms 4 are provided at the hinge points between the top profile 1 and the two side profiles 2, and at the hinge points between the bottom profile 3 and the two side profiles 2. The locking mechanisms 4 are used to control the bottom profile 3 and the two side profiles 2 at adjacent hinge points to lock when unfolded or unlock when folded.

[0020] The locking mechanism 4 includes a locking pin 401 and a preload spring 402. The locking pin 401 is slidably disposed on one of the top profile 1 and the side profile 2 at the hinge, and on one of the bottom profile 3 and the side profile 2 at the hinge. Locking holes 403 matching the locking pins 401 are provided on one of the top profile 1 and the side profile 2 at the hinge, and on the other of the bottom profile 3 and the side profile 2 at the hinge. That is, in this embodiment, the locking hole 403 can be on the top profile 1 at the hinge, and the corresponding locking pin 401 is slidably disposed on the side profile 2. Alternatively, in another embodiment, the locking hole 403 is on the side profile 2, and the corresponding locking pin 401 is slidably disposed on the top profile 1. In this embodiment, the locking hole 403 can be on the bottom profile 3 at the hinge, and the corresponding locking pin 401 is slidably disposed on the side profile 2. Alternatively, in another embodiment, the locking hole 403 is on the side profile 2, and the corresponding locking pin 401 is slidably disposed on the bottom profile 3. The locking pin 401 is disposed in the locking hole 403, and the preload spring 402 is used to preload the locking pin 401 and keep it always in the locking hole 403 when locked.

[0021] A sliding hole 404 is provided on one of the top profile 1 and the side profile 2 at the hinge, and on one of the bottom profile 3 and the side profile 2 at the hinge. In other words, the locking pin 401 in this embodiment is slidably disposed on the side profile 2, and the sliding hole 404 is also disposed on the side profile 2. One end of the locking pin 401 is slidably disposed in the sliding hole 404. A first limiting mechanism 405 and a second limiting mechanism 406 are respectively provided on the locking pin 401. The sliding hole 404 is located between the first limiting mechanism 405 and the second limiting mechanism 406. The first limiting mechanism 405 and the second limiting mechanism 406 cooperate with each other to limit the sliding range of the locking pin 401. A preload spring 402 is disposed between the first limiting mechanism 405 and the sliding hole 404.

[0022] In this embodiment, the locking pin 401 is a bolt, and the second limiting mechanism 406 is a head set at one end of the bolt and located at one end of the sliding hole 404; The first limiting mechanism 405 is a nut, and the bolt and the nut are threaded together. The preload spring 402 is a cylindrical spring, which is sleeved on the locking pin 401. One end of the preload spring 402 abuts against the other end of the sliding hole 404, and the other end of the preload spring 402 abuts against the nut. By adjusting the position of the nut on the bolt at the first limiting mechanism 405, the preload force of the preload spring 402 can be changed, which in turn changes the sliding force of the locking pin 401, thus facilitating the control of the locking pin 401.

[0023] A protruding latch 407 is provided on one of the top profile 1 and the side profile 2 at the hinge, and on the other of the bottom profile 3 and the side profile 2 at the hinge. In this embodiment, the latch 407 is provided on the top profile 1 and the bottom profile 3, and the locking hole 403 is provided on the latch 407. The end of the latch 407 away from the locking pin 401 is curved, and the cross-sectional area gradually increases from the outside to the inside. To prevent interference, the latch 407 is designed so that the cross-sectional area gradually increases from its cantilevered end to its fixed end, avoiding interference during the expansion or contraction rotation of the control frame. One of the top profile 1 and the side profile 2 at the hinge, and one of the bottom profile 3 and the side profile 2 at the hinge, are provided with a locking groove 408 that matches the locking tongue 407. A through hole 409 is provided at one end of the locking groove 408 near the sliding hole 404. The through hole 409 communicates with the locking groove 408 and is coaxially arranged with the sliding hole 404. One end of the locking pin 401 passes through the through hole 409 and is located within the locking groove 408, and one end of the locking tongue 407 is located within the locking groove 408. A pull ring 410 is provided on the locking pin 401, and the pull ring 410 is fixedly connected to the head of the second limiting mechanism 406.

[0024] In this embodiment, the top profile 1 includes two hinged upper crossbars 101, and the bottom profile 3 includes two hinged lower crossbars 201. The top profile 1 is made into two hinged upper crossbars 101, and the bottom profile 3 is made into two hinged lower crossbars 201, mainly to facilitate the locking mechanism 4 at the hinge of the top profile 1 and the locking mechanism 4 at the hinge of the bottom profile 3 to control locking or unlocking. The locking mechanism 4 forms a hidden structure inside the frame, and the overall structure is compact and beautiful.

[0025] Example 2 is an application of Example 1, specifically: a light box equipped with a quick-assembly folding display rack as described above.

[0026] The principle is as follows: When unfolding, pull the folding upper crossbar 101 in the top profile 1 upwards, and drive the folding upright bar 301 on the side profile 2 to gradually unfold until the predetermined locking position is reached. Then, pull the ring 410 on the locking mechanism 4 at the hinge of the upper and lower ends of the side profile 2 in sequence, and drive the locking pin 401 to slide in the sliding hole 404, and compress the pre-tension spring 402. At the same time, one end of the locking pin 401 will disengage from the through hole 409 and allow the locking tongue 407 to enter the locking groove 408. When the locking tongue 407 reaches the locking position, that is, the locking hole 403 and one end of the locking pin 401 correspond to each other, release the ring 410, and under the action of the pre-tension spring 402, one end of the locking pin 401 passes through the through hole 409 and enters the locking hole 403 on the locking tongue 407 in the locking groove 408 to achieve locking. Install the above steps to lock each locking mechanism 4 in sequence to complete the frame unfolding. Similarly, when folding, pull the ring 410, which will cause the hinge of the side profile 2 and the top profile 1 to rotate relative to each other, and cause the locking tongue 407 to disengage from the locking groove 408. By following these steps, the frame can be folded. The operation is simple and easy for workers to operate.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
