Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, specifically to the support structure of a folding table. Background Technology
[0002] Tables are essential household items, widely used in homes and offices. To avoid taking up too much space when not in use, various foldable tables have emerged on the market. They are frequently used in temporary reception venues such as banquets, meetings, and exhibitions, and have become indispensable furniture in hotels, exhibitions, and other similar settings.
[0003] Existing folding tables typically include a tabletop and a support frame located below the tabletop. The entire folding table can be folded using the support frame to make full use of space.
[0004] Currently, existing folding table supports typically include a frame with four legs hinged to it. The legs usually have feet at the bottom, typically made of rubber, plastic, or wood, which serve to prevent slipping, keep the table from wobbling, and avoid scratching the floor, thus protecting the floor. However, because the feet are in direct contact with the floor, friction occurs during moving the folding table. Over time, the feet are prone to wear and even deformation, affecting usability and requiring replacement. However, since the feet are firmly pressed to the floor by the table legs, replacing them requires flipping the entire folding table so the feet are facing upwards. This is difficult due to the large size and weight of folding tables, making the flipping process challenging. Utility Model Content
[0005] The purpose of this utility model is to provide a support structure for a folding table in order to solve the above-mentioned problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a folding table support structure, including a frame, on which four table legs are provided, each table leg including a connecting leg and a support rod arranged coaxially, one end of the support rod being provided with a connecting rod and the other end being provided with a telescopic rod, the telescopic rod being able to extend or retract into the connecting leg, and a pad being fitted on the connecting rod, the pad being made of rubber material.
[0007] As a further feature of this invention, the pad is provided with a socket for inserting a connecting rod, the side wall of the socket is provided with a groove, and the connecting rod is provided with a protruding ring for embedding into the groove.
[0008] As a further feature of this utility model, an annular groove is provided circumferentially inside the connecting leg, and a slot communicating with the annular groove is provided vertically inside the connecting leg. A locking block is provided on the side wall of the telescopic rod for sequentially locking into the slot and the annular groove.
[0009] As a further feature of this invention, the connecting leg has a cavity communicating with the annular groove, a spring is provided inside the cavity, and a support plate is connected to the end of the spring away from the cavity. The telescopic rod is rotatably connected to the support plate.
[0010] As a further feature of this invention, an elastic block is provided on the top wall of the annular groove for contacting the locking block, and the elastic block is made of rubber material.
[0011] As a further feature of this invention, the support leg is provided with a grip ring, and the side wall of the grip ring is provided with several anti-slip grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] When the feet need to be replaced, this invention simply requires removing the feet from all four table legs in sequence. During operation, any corner of the frame can be lifted upwards, and the support rod at that position can be pulled upwards, causing the telescopic rod to retract into the connecting leg. This moves the connecting rod upwards, lifting the foot. Because of the support from the other table legs, the foot on that leg remains suspended, allowing the old foot to be peeled off the connecting rod. A new foot can then be fitted, and the support rod pulled downwards, causing the telescopic rod to extend beyond the connecting leg. This moves the connecting rod downwards, allowing the foot to fall until it touches the floor, thus replacing the foot. This process is repeated until all four table legs have been replaced. There is no need to flip the entire folding table, making the operation easy, effortless, and convenient. Attached Figure Description

[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 , Figure 2 , Figure 7As shown, the support structure of the folding table includes a frame 1 with four legs. Each leg includes a connecting leg 2 and a support rod 3 coaxially arranged. A connecting rod 4 is attached to one end of the support rod 3, and a telescopic rod 5 is attached to the other end. The telescopic rod 5 can extend or retract into the connecting leg 2. A foot 6, made of rubber, is fitted onto the connecting rod 4. To replace the foot 6, simply remove the foot 6 from each of the four legs in sequence. During operation, any corner of the frame 1 can be lifted upwards, and the support rod 3 at that position can be pulled upwards, causing the telescopic rod 5 to retract into the connecting leg 2. This moves the connecting rod 4 upwards, raising the foot 6. Due to the support of the other legs, the foot 6 of that leg can remain suspended. The old foot 6 can then be peeled off the connecting rod 4, and a new foot 6 can be fitted. Finally, the support rod is pulled downwards, causing the telescopic rod 5 to extend out of the connecting leg 2. Externally, the connecting rod 4 moves downward, allowing the foot 6 to fall until it contacts the floor, enabling the foot 6 to be removed and replaced. This process is repeated until all four table legs have had their feet replaced. The entire folding table does not need to be flipped over, making the operation easy, effortless, and simple. The foot 6 has a hole 7 for inserting the connecting rod 4, and a groove 8 on the side wall of the hole 7. The connecting rod 4 has a protruding ring 9 for embedding into the groove 8. When installing the foot 6, it can be pulled to both sides to cause elastic deformation, expanding the hole 7. Then, the connecting rod 4 is inserted into the hole 7, allowing the protruding ring 9 to pass through and be inserted into the groove 8. The foot 6 is then released, allowing it to be fitted onto the connecting rod 4. This convenient operation, combined with the groove 8's restraint on the protruding ring 9, enhances the stability of the foot 6 on the connecting rod 4, preventing it from falling off.
[0024] Please see Figure 2-7As shown, an annular groove 10 is provided circumferentially inside the connecting leg 2, and a slot 11 communicating with the annular groove 10 is provided vertically inside the connecting leg 2. A locking block 12 is provided on the side wall of the telescopic rod 5 for sequentially engaging the slot 11 and the annular groove 10. When it is necessary to retract the telescopic rod 5 into the connecting leg 2, the telescopic rod 5 can be retracted into the connecting leg 2, causing the slot 11 to slide from the slot 11 to the point where the slot 11 communicates with the annular groove 10. Then, the telescopic rod 5 is rotated, causing the locking block 12 to engage with the annular groove 10, thereby enabling… The telescopic rod 5 can be retracted to raise the foot 6. When it is necessary to extend the telescopic rod 5 outside the connecting leg 2, the telescopic rod 5 can be rotated so that the locking block 12 rotates to the position where the annular groove 10 and the locking groove 11 communicate. It can then disengage through the locking groove 11, allowing the telescopic rod 5 to extend and the foot 6 to fall. A cavity 13 communicating with the annular groove 10 is provided inside the connecting leg 2, and a spring 14 is provided inside the cavity 13. A support plate 15 is connected to the end of the spring 14 away from the cavity 13, and the telescopic rod 5 is rotatably connected to the support plate 15. On the disc 15, when the locking block 12 is limited by the annular groove 10, the spring 14 is compressed and deformed accordingly. When the annular groove 10 is released from limiting the locking block 12, the spring 14 can automatically extend and return to its original shape, thereby pushing the telescopic rod 5 outward to extend outside the connecting leg 2, so that the pad 6 is reset. The operation is relatively convenient. An elastic block 16 is provided on the top wall of the annular groove 10 for contacting the locking block 12. The elastic block 16 is made of rubber material. After the locking block 12 is inserted into the annular groove 10, it will contact the elastic block. When the elastic block 16 is compressed, it undergoes elastic deformation. The elastic block 16 then applies a thrust to the locking block 12 in the opposite direction, firmly pressing it against the bottom wall of the annular groove 10. This makes the connection of the locking block 12 inside the annular groove 10 more stable and less prone to loosening. A gripping ring 17 is provided on the support leg 3, and several anti-slip grooves 8 are provided on the side wall of the gripping ring 17. By gripping the gripping ring 17 and applying force, the support leg 3 can be moved up and down. The anti-slip grooves 8 make it less likely to slip when gripping the gripping ring 17, and make it easier to apply force.
