[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a technical solution: a foldable and retractable display rack with a concealed load-bearing reinforcement structure, including a first side support 1 and a second side support 3. The inner walls of both the first side support 1 and the second side support 3 have grooves. First movable partitions 2 and second movable partitions 4 are respectively inserted into the grooves of the first side support 1 and the second side support 3. Multiple sets of first movable partitions 2 and second movable partitions 4 are provided. Each set of first movable partitions 2 and second movable partitions 4 is longitudinally and equally spaced about the inner side of the first side support 1 and the second side support 3. One side of the first movable partitions 2 and second movable partitions 4 is fixed to the first side support 1 and the second side support 3 by screws. This structure ensures that the first movable partitions 2 and second movable partitions 4 can be stored in a concealed load-bearing structure after installation. Stable, the first movable partition 2 and the second movable partition 4 can be folded when rotated downwards, ensuring uniform height on both sides of the first movable partition 2 and the second movable partition 4. One end of the first side bracket 1 and the second side bracket 3 is provided with an annular groove. One end of the fixing bolt 75 passes through the crank handle 74 and is threaded into the annular groove of the first side bracket 1 and the second side bracket 3. This structure can fix the crank handle 74 and the rotating shaft 72 through the fixing bolt 75, preventing the support roll 73 from loosening due to the rotation of the crank handle 74 and the rotating shaft 72. The bottom sides of the first movable partition 2 and the second movable partition 4 are provided with guide components 5. The guide components 5 include through-slots 51 fixed to the bottom of the first movable partition 2 and the second movable partition 4. This structure uses through-slots 51... The support roll 73 can be concealed, improving the aesthetics of the device. Openings are provided on the inner side and top of the guide groove 51 to facilitate the fit of the support roll 73 with the first movable partition 2 and the second movable partition 4. A limiting rod 52 is fixedly connected to the inner wall of the guide groove 51. One end of the support roll 73 is guided by the limiting rod 52 to fit against the bottom of the first movable partition 2 and the second movable partition 4. This structure, through the limiting rod 52, can support and limit the support roll 73, ensuring a tight fit between the support roll 73 and the first movable partition 2 and the second movable partition 4. The first movable partition 2 and the second movable partition 4 are connected by a hinge. A first support assembly 7 and a second support assembly 6 are respectively provided inside the grooves of the first side bracket 1 and the second side bracket 3. The first support assembly 7 and the second support assembly 6... Component 6 has the same structure. The first support assembly 7 includes a box 71 fixed to the inner wall of the groove of the first side bracket 1. The top of the box 71 has an opening. The outer wall of the box 71 is fixed to the inner wall of the groove of the first side bracket 1 and the second side bracket 3 by screws. The box 71 with this structure can be completely disassembled from the inside of the first side bracket 1, which is convenient for replacing the box 71 as a whole. A rotating shaft 72 is rotatably connected inside the box 71. A support roll 73 is wound around the outer wall of the rotating shaft 72. One end of the support roll 73 is connected to the rotating shaft 72 of the second support assembly 6. The top of the support roll 73 is tightly attached to the bottom of the first movable partition 2 and the second movable partition 4. A crank 74 is connected to one end of the rotating shaft 72. The crank 74 is located at one end of the first side bracket 1 and is fixedly connected to one end of the rotating shaft 72.This structure allows the rotating shaft 72 to rotate by turning the crank handle 74, thereby releasing the support roll 73 on the rotating shaft 72 and tightening the support roll 73 on the second support assembly 6. This ensures the support roll 73 is taut, providing support for the first movable partition 2 and the second movable partition 4. A fixing bolt 75 is threaded onto the crank handle 74, with one end of the bolt 75 connected to the first side bracket 1. The tightness of the support roll 73 can be adjusted, and the tightness determines the support effect. The support roll 73 is made of composite fiber mesh, and the ends of the support rolls 73 on the second support assembly 6 and the first support assembly 7 can be sewn together for fixation.

[0026] Working principle: When using the concealed load-bearing reinforcement structure of this foldable display rack, firstly, insert one side of the first movable partition 2 and the second movable partition 4 from the top of the first side bracket 1 and the second side bracket 3. Then, use screws to fix the first movable partition 2 and the second movable partition 4 to the first side bracket 1 and the second side bracket 3. Next, fix the box 71 of the first support assembly 7 and the second support assembly 6 to the inner wall of the groove of the first side bracket 1 and the second side bracket 3. Then, pull out one end of the support roll 73 of the first support assembly 7 and pass it through the first side bracket 1 and the second side bracket 3. The limiting rods 52 at the bottom of the side bracket 1 and the second side bracket 3 are fixedly connected to the support roll 73 of the second support assembly 6. Then, the overall tightness of the support roll 73 is adjusted. During adjustment, the crank handle 74 is turned so that the crank handle 74 drives the rotating shaft 72 to rotate and tighten the support roll 73. Then, the crank handle 74 is fixed to the first side bracket 1 with the fixing bolts 75 to complete the installation. At this time, the support roll 73 is stably attached to the bottom of the first movable partition 2 and the second movable partition 4 to ensure the load-bearing effect of the first movable partition 2 and the second movable partition 4.
