[0002] A display rack is a support frame used to display promotional posters, restaurant menus, creative advertisements, or announcements. It is common in daily life and has a wide range of uses.

[0003] A patent search revealed a sliding telescopic support for display racks, publication number CN219762979U. This support comprises a fixed part, a first sliding part, and a second sliding part, which are slidably disposed within the fixed part to achieve telescopic movement. The first and second sliding parts can partially or completely overlap, allowing the support to be retracted to a smaller size, occupying less space and making it easy to carry. However, it lacks a limiting device, making it prone to movement of the first and second sliding parts when placing display panels, potentially causing the display panels to shift or tilt, affecting the aesthetics of the display and making it relatively inconvenient to use. Therefore, we propose a sliding telescopic support for display racks to solve or improve upon these problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-8The system includes a fixed frame 1, a first sliding groove 10 formed on the inner surface of the fixed frame 1, a second sliding groove 11 formed on the inner surface of the fixed frame 1, the second sliding groove 11 being located on one side of the bottom of the first sliding groove 10, a first sliding frame 2 slidably mounted on the inner surface of the fixed frame 1 via the first sliding groove 10, and a second sliding frame 3 slidably mounted on the inner surface of the fixed frame 1 via the second sliding groove 11. The first sliding frame 2 is located on one side of the top of the second sliding frame 3, and the first sliding frame 2 and the second sliding frame 3 can partially or completely overlap. A second toothed slot 9 is formed at the bottom of the first sliding frame 2, a first toothed slot 4 is formed at the bottom of the second sliding frame 3, a structural reinforcing rib 12 is fixed to the bottom of the inner surface of the fixed frame 1, the structural reinforcing rib 12 can enhance the rigidity of the fixed frame 1, and reduce the deformation and shaking of the fixed frame 1 when the first sliding frame 2 and the second sliding frame 3 move, a second fixing hole 8 is formed on the surface of the first sliding frame 2, and several sets of second fixing holes 8 are formed on the surface of the fixed frame 1. An opening is provided on one side of the second fixing hole 8 on the surface of the fixed frame 1, and an insert is placed inside the opening. A second fixing bolt 7 is provided, which can be inserted into the second fixing hole 8, thereby restricting the position of the first sliding frame 2 through the second fixing hole 8, preventing the first sliding frame 2 from moving further. A limit block is fixed to the surface of the second fixing bolt 7, which can restrict the position of the second fixing bolt 7 and prevent the second fixing bolt 7 from detaching from the inside of the fixing frame 1. A first fixing hole 5 is opened on the surface of the second sliding frame 3, and several sets of the first fixing holes 5 are opened on the surface of the second sliding frame 3. An opening is provided on the surface of the fixing frame 1 at one side of the first fixing hole 5, and a first fixing bolt 6 is inserted into the opening. The first fixing bolt 6 can be inserted into the first fixing hole 5, thereby restricting the position of the second sliding frame 3 through the first fixing hole 5, preventing the second sliding frame 3 from moving further. A limit block is fixed to the surface of the first fixing bolt 6, which can restrict the position of the first fixing bolt 6 and prevent the first fixing bolt 6 from detaching from the inside of the fixing frame 1. The limiting component A is provided inside the structural reinforcing rib 12.

[0024] The limiting component A contains a connecting rod 14 inserted inside the structural reinforcing rib 12. A limiting plate is fixed to the surface of the connecting rod 14 inside the structural reinforcing rib 12. The limiting plate can restrict the position of the connecting rod 14 and prevent the connecting rod 14 from detaching from the interior of the structural reinforcing rib 12. An opening is provided at the bottom of the fixing frame 1 on one side of the connecting rod 14. One end of the connecting rod 14 can pass through the interior of the opening and is fixed to the toothed block 13 at the top of the connecting rod 14. When the toothed block 13 moves, it will drive the fixed connecting rod 14 to move. A spring 15, fitted onto the surface of the connecting rod 14, is located inside the structural reinforcing rib 12. One end of the spring 15 contacts a fixed limiting plate on the surface of the connecting rod 14, and the other end contacts the inner surface of the structural reinforcing rib 12. When the connecting rod 14 moves, it drives the fixed limiting plate to move. When the limiting plate moves, it squeezes one end of the spring 15 in contact with the surface and causes it to deform. When there is no external interference, the spring 15 pushes the connecting rod 14 back to its initial position through the limiting plate. The limiting component A is located on the structural reinforcing rib 12. The internal structure has several sets of components. One set of limiting components A has a toothed block 13 that engages with the second toothed slot 9. When the first sliding frame 2 moves, it drives the second toothed slot 9 at the bottom to move. When the second toothed slot 9 moves, its surface presses against the surface of the toothed block 13, causing the toothed block 13 to move. When the first sliding frame 2 moves to the appropriate position, the toothed block 13 returns to its initial position via the spring 15 and re-engages with the second toothed slot 9. Another set of limiting components A has a toothed block 13 that engages with the first toothed slot 4. When the second sliding frame 3 moves, it drives the first toothed slot 4 at the bottom to move. When the first toothed slot 4 moves, its surface presses against the surface of the toothed block 13, causing the toothed block 13 to move. When the second sliding frame 3 moves to the appropriate position, the toothed block 13 returns to its initial position via the spring 15 and re-engages with the first toothed slot 4. At the same time, by adjusting the sliding positions of the first sliding frame 2 and the second sliding frame 3, the bracket can be adapted to display boards of different widths, improving the applicability and compatibility of the bracket.

[0025] Working principle: When the display rack is needed, pulling the first sliding frame 2 and the second sliding frame 3 allows them to slide out from one side of the inner surface of the fixed frame 1 via the first sliding groove 10 and the second sliding groove 11. After the first sliding frame 2 and the second sliding frame 3 are adjusted to the appropriate position, the connecting rod 14 and the toothed block 13 are moved by the spring 15, so that the toothed block 13 engages with the second toothed slot 9 and the first toothed slot 4, thereby restricting the position of the first sliding frame 2 and the second sliding frame 3 to a certain extent, avoiding or reducing their movement when placing the display board. This reduces or avoids the problem of the display board shifting or tilting, which affects the aesthetics of the display. It is relatively convenient to use. When the display rack needs to be used stably for a long time, the position of the second sliding frame 3 can be fixed by inserting the first fixing bolt 6 into the first fixing hole 5, and the position of the first sliding frame 2 can be fixed by inserting the second fixing bolt 7 into the second fixing hole 8. This prevents the first sliding frame 2 and the second sliding frame 3 from moving during the use of the display rack, improving the stability of the display rack during long-term use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
