Abstract
Description
Technical Field
[0001] This utility model relates to the field of table leg technology, specifically to a concealed telescopic table leg structure. Background Technology
[0002] Table legs are the vertical structures that support the tabletop, and are usually made of wood, metal, or other materials. Most existing table legs are fixed and difficult to change.
[0003] Even if existing table legs can be modified, their function is limited to either concealed or retractable. Concealed legs are stored under the tabletop for easy table storage and to reduce space occupation when not in use. Retractable legs can be extended or retracted to adjust the height of the tabletop, making them convenient for people of different heights. Therefore, a concealed retractable table leg structure is needed that combines concealment and retraction for ease of use. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a concealed telescopic table leg structure, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a concealed telescopic table leg structure, including a fixed frame, two rotating rods are rotatably connected inside the fixed frame, a fixed cylinder is fixed to the outer wall of the rotating rod, a support rod is slidably connected inside the fixed cylinder, multiple insertion holes are opened on the right side of the fixed cylinder, a round hole is opened on the right side of the support rod, and a compression spring is fixed inside the round hole;
[0006] The compression spring has an insert block fixed inside, the rotating rod has a fixing hole inside, the fixing hole has a fixing plate fixed inside, the fixing plate has a sliding connection to a moving rod inside, and the two ends of the moving rod are respectively fixed with a locking block and a top block;
[0007] The rotating rod is rotatably connected to a compression rod, and the outer wall of the compression rod has a groove. The right side of the fixing frame is integrally formed with an inclined part. The bottom of the top block has an annular groove, and a compression spring is fixed inside the annular groove. The fixing frame has multiple locking holes inside.
[0008] Preferably, the rotating rod has two limiting holes inside, a limiting spring is fixed inside the limiting hole, and a limiting block is fixed at the other end of the limiting spring.
[0009] Preferably, both ends of the extrusion rod are curved.
[0010] Preferably, a pad is fixed to the bottom of the support rod.
[0011] Preferably, the pad has a structure that is narrow at the top and wide at the bottom.
[0012] Preferably, the pad is made of rubber.
[0013] Preferably, the top of the fixing frame has multiple mounting holes.
[0014] Beneficial effects
[0015] This utility model provides a concealed telescopic table leg structure. Compared with the prior art, it has the following advantages:
[0016] This concealed telescopic table leg structure uses a rotating rod, a fixed cylinder, a support rod, an insert block, an inclined section, a pressing rod, a top block, a moving rod, and an insert block to fix the bottom of the fixed frame and the tabletop. Rotating the pressing rod aligns the groove of the top block with the top block, causing a compression spring to push the top block, the moving rod, and the locking block to move. The locking block moves out of its locking hole, allowing the fixed cylinder to rotate. After opening or retracting the fixed cylinder, rotating the pressing rod again presses against the top block, causing the top block to move along with the moving rod and the locking block. The locking block then engages with its locking hole, thus restricting the rotation of the fixed cylinder and fixing it in place. After opening the fixed cylinder, pressing the insert block allows it to enter the round hole, pulling the support rod downwards. This allows adjustment of the device's length and the tabletop height. Attached Figure Description

[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 Figures 1 to 6 This utility model provides a technical solution: a concealed telescopic table leg structure, including a fixed frame 9, with two rotating rods 7 rotatably connected inside the fixed frame 9. A fixed cylinder 3 is fixed to the outer wall of the rotating rod 7, and a support rod 2 is slidably connected inside the fixed cylinder 3. Multiple insertion holes 4 are opened on the right side of the fixed cylinder 3, and a round hole 22 is opened on the right side of the support rod 2. A compression spring 23 is fixed inside the round hole 22, and an insertion block 6 is fixed inside the compression spring 23. A fixed hole 15 is opened inside the rotating rod 7, and a fixed plate 12 is fixed inside the fixed hole 15. A moving rod 13 is slidably connected inside the fixed plate 12. The two ends of the 3 are respectively fixed with a locking block 14 and a top block 16. The inside of the rotating rod 7 is rotatably connected to a pressing rod 5. The outer side wall of the pressing rod 5 has a groove 19. The right side of the fixing frame 9 has an integrally formed inclined part 18. The bottom of the top block 16 has an annular groove 21. A compression spring 20 is fixed inside the annular groove 21. The inside of the fixing frame 9 has multiple locking holes 24, which can hide and extend the table legs for easy storage of the table. The two ends of the pressing rod 5 are curved, which makes it easy to rotate the pressing rod 5. The top of the fixing frame 9 has multiple mounting holes 8, which can be used to fix the fixing frame 9 to the tabletop with screws.
[0026] Furthermore, two limiting holes 10 are provided inside the rotating rod 7. A limiting spring 11 is fixed inside the limiting hole 10, and a limiting block 17 is fixed at the other end of the limiting spring 11. This can limit the rotation of the pressing rod 5.
[0027] Furthermore, a pad 1 is fixed to the bottom of the support rod 2 for easy support. The pad 1 has a structure that is narrow at the top and wide at the bottom, which can provide better stable support. The pad 1 is made of rubber, which can increase friction.
[0028] During operation, the fixed frame 9 is fixedly connected to the bottom of the tabletop. Rotating the pressing rod 5 aligns the top block 16 with the groove 19. The pressing spring 20 pushes the top block 16, the moving rod 13, and the locking block 14 to move. The locking block 14 moves out of the locking hole 24, allowing the fixed cylinder 3 to rotate. After opening or closing the fixed cylinder 3, rotating the pressing rod 5 again presses the top block 16, causing the top block 16 to move along with the moving rod 13 and the locking block 14. The locking block 14 engages with the locking hole 24, thus restricting the rotation of the fixed cylinder 3 and fixing it in place. After opening the fixed cylinder 3, pressing the insert block 6 allows the insert block 6 to enter the round hole 22. Pulling the support rod 2 downwards allows adjustment of the device's length and the tabletop height.
