[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 7 This embodiment provides a folding table, including a tabletop 1 and four table legs 2 (hereinafter referred to as table legs 2) with stepless telescopic structure. The four table legs 2 are rotatably connected to the bottom surface of the tabletop 1.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, every two table legs 2 are connected by a connecting frame 4 to form a set of table legs 2, and the two sets of table legs 2 are arranged opposite each other along the length of the tabletop 1. Of course, in other embodiments, the number of table legs 2 is not limited to this, such as 3, 5 or 6 or more.

[0030] like Figure 3 and Figure 7As shown, more specifically, each table leg 2 includes a first leg tube 21, a second leg tube 22 that can extend and retract relative to the first leg tube 21 along its axial or longitudinal direction, and a locking assembly 23 disposed between the first leg tube 21 and the second leg tube 22. The first leg tube 21 and the second leg tube 22 are arranged vertically, with the upper end of the second leg tube 22 movably inserted into the first leg tube 21. The upper end of the first leg tube 21, away from the second leg tube 22, is rotatably connected to the bottom surface of the tabletop 1. The lower end of each second leg tube 22 is provided with a foot pad 5 for supporting the ground.

[0031] The locking assembly 23 includes a rack 231, an elastic return member 232, a connecting seat 237, and a rotatable rotating handle 233. The rotating handle 233 has toothed portions 236 and button portions 234 located at its axial ends, and a hinge hole 235 located between the toothed portions 236 and the button portions 234. The rack 231 is installed inside the second leg tube 22, and the elastic return member 232 is a spring. Of course, a straight opening is provided on one side of the outer wall of the second leg tube 22 to expose the toothed grooves of the rack 231.

[0032] In specific implementation, such as Figure 3 As shown, the connector 237 is sleeved on the lower end of the first leg tube 21 facing the second leg tube 22, and the second leg tube 22 is movably inserted through the through channel of the connector 237 and inserted into the first leg tube 21.

[0033] The rotating handle 233 is rotatably mounted in the mounting groove of the connecting seat 237 through the cooperation of the hinge shaft 238 and the hinge hole 235, so as to ensure that the rotating handle 233 can rotate around the hinge shaft 238 at a fixed point.

[0034] Furthermore, an elastic reset member 232 is provided between the connector 237 and the button part 234, and the connector 237 has a relief groove for the movable relief tooth part 236, and the relief groove is connected to the through channel so that the relief tooth part 236 can be separably engaged with the tooth groove of the rack 231 inside the second foot tube 22.

[0035] When the button part 234 is not subjected to external force, the elastic reset member 232 applies its own elastic force to the button part 234, forcing the convex tooth part 236 of the rotating handle 233 to rotate toward the rack 231 until it is engaged with the tooth groove of the rack 231. At this time, the rack 231 is restricted by the convex tooth part 236 and cannot move, that is, the telescopic length between the first leg tube 21 and the second leg tube 22 is also fixed. Moreover, the meshing relationship between the convex tooth part 236 and the rack 231 ensures a reliable locking force. Therefore, this embodiment has better load-bearing performance and stability.

[0036] When the button 234 is pressed down with a finger and the elastic force of the elastic reset member 232 is overcome, the engagement between the rack 231 and the toothed part 236 can be unlocked. In the unlocked state, the second leg tube 22 can be pulled out from the first leg tube 21 or inserted further to adjust the desired table leg length or height, thereby adjusting the tabletop 1 to a suitable height position. Therefore, this embodiment can unlock and lock the telescopic leg tube through a simple pressing action, that is, the table leg height can be adjusted by a single finger pressing operation.

[0037] Through the combined action of the rack 231, the elastic reset member 232, and the rotating handle 233, the elastic reset member 232 applies a spring force to the button portion 234 of the rotating handle 233 to restrict the rotation, so that the protruding tooth portion 236 rotates toward the rack 231 and can be separably engaged with the tooth groove of the rack 231. The rack 231 has multiple continuously distributed tooth grooves to correspond to multiple adjustment positions of different table leg extension lengths, thereby realizing stepless adjustment of the extension length between the first leg tube 21 and the second leg tube 22.

[0038] In summary, since this embodiment adopts a rack and pinion structure, the telescopic length between the first leg tube 21 and the second leg tube 22 can be infinitely adjustable, that is, the height of the table legs can be arbitrarily and continuously adjusted without being limited by the number of adjustment levels. This provides users with more adjustment function options, thereby meeting more product usage scenarios for users.

[0039] In addition, compared with the existing technology, this embodiment can optimize the complexity and difficulty of operation by extending the legs, thereby quickly and conveniently realizing stepless adjustment of the extension length of the table legs. Moreover, the overall structure is simple and compact, and does not affect the overall volume of the folding table after storage.

[0040] Of course, in other embodiments, a sliding rail structure or a sliding groove structure can also be used to form a telescopic joint between the first leg tube 21 and the second leg tube 22; the connecting seat 237 can also be sleeved on the upper end of the second leg tube 22, and the first leg tube 21 is equipped with a rack 231, that is, the installation positions of each other can be interchanged, which can also realize stepless adjustment of the extension length of the table leg; in addition, the elastic reset member 232 can also adopt a spring sheet structure.

[0041] In another preferred embodiment, such as Figure 1 and Figure 2 As shown, the tabletop 1 includes a first half 11 and a second half 12 pivotally connected to the first half 11, and two sets of table legs 2 are respectively pivotally connected to the first half 11 and the second half 12. Of course, in other embodiments, the tabletop 1 may also adopt a straight board structure that cannot be folded or split.

[0042] like Figure 4 , Figure 5 and Figure 6As shown, when folding, first fold the two sets of table legs 2 to the bottom of the first half 11 and the second half 12 respectively, and then fold the two halves in half to complete the folding of the table. This can further reduce the overall folded volume.

[0043] Further preferred, such as Figure 5 As shown, the connecting frame 4 of the two sets of table legs 2 are connected to the first half 11 and the second half 12 respectively through elastic elements. The specific elastic element is a gas spring 3, and the table legs 2 are folded towards the table board 1 by the elastic force of the gas spring 3, which is conducive to the quick folding of the folding table.

[0044] Further preferred, such as Figure 5 As shown, a rotatable support member 13 is provided between the first half 11 and the second half 12.

[0045] When unfolded, one end of the support member 13 is rotatably connected to the first half 11, and the other end is fastened to the second half 12, thus achieving stable support for the first half 11 and the second half 12.

[0046] When folding, rotate the support 13 in the opposite direction to release the fastening relationship between the support 13 and the second half 12, thereby facilitating the next step of folding the two halves of the table 1 in half.

[0047] Further preferred, such as Figure 7 As shown, the surface of the button part 234 is provided with an anti-slip surface to provide an anti-slip function.

[0048] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
