[0001] This utility model relates to the field of outdoor leisure technology, and in particular to a folding table. Background Technology

[0002] Folding tables are a type of furniture that saves space through their folding structure, making them especially suitable for outdoor camping scenarios.

[0003] Many folding tables on the market have the problem of insufficient load-bearing capacity of the tabletop. They rely solely on the support points between the table legs and the tabletop for support, resulting in excessive concentration of stress points. This leads to uneven stress distribution on the tabletop and ultimately instability. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a folding table that, through the cooperation of a linkage mechanism, provides stable support for the tabletop when unfolded, while avoiding excessive concentration of stress points.

The second leg tube is telescopic relative to the first leg tube, and the telescopic length between the first leg tube and the second leg tube is infinitely adjustable through the locking assembly.

[0011] Furthermore, the locking assembly includes a rack, an elastic reset member, and a rotatable rotating handle. One end of the rotating handle has a toothed portion, and the elastic reset member applies an elastic force to the other end of the rotating handle away from the toothed portion to restrict the rotation of the toothed portion toward the rack, and the toothed portion is separably engaged with the groove of the rack.

[0022] 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.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 4 This embodiment provides a folding table, including a tabletop 1, a linkage mechanism, and a first table leg assembly 2 and a second table leg assembly 3 arranged opposite each other along the left and right longitudinal directions of the tabletop 1. The tabletop 1 includes a first table panel 11 and a second table panel 12 arranged to the left and right and pivotally connected to each other. The first table leg assembly 2 and the second table leg assembly 3 are respectively pivotally connected to the first table panel 11 and the second table panel 12. At this time, the first table panel 11 and the second table panel 12 are each half of the tabletop 1. Of course, in other embodiments, the areas of the first table panel 11 and the second table panel 12 may also be different.

[0025] The first table panel 11, the second table panel 12, and the two table leg assemblies are rotatably connected to the linkage mechanism to provide stable support for the table panel 1 when it is unfolded.

[0026] like Figure 1 and Figure 2As shown, the linkage mechanism of this embodiment includes two linkage assemblies 4, which are distributed along the front and rear transverse sides of the tabletop 1, respectively. Each linkage assembly 4 includes a first connector 41, a second connector 42, a third connector 43, and a fourth connector 44. The first connector 41 and its corresponding third connector 43 in each group are hinged to connection point A, and the second connector 42 and its corresponding fourth connector 44 in each group are hinged to connection point B. The upper end of the first connector 41 in each group, away from the third connector 43, is rotatably connected to the first tabletop 1. 1. A connection point C is formed. The upper end of the second connecting member 42 of each group is rotatably connected to the second table board member 12 away from the fourth connecting member 44, forming a connection point D. The middle part of the third connecting member 43 of each group is rotatably connected to the first table leg group 2, forming a connection point F. The middle part of the fourth connecting member 44 of each group is rotatably connected to the second table leg group 3, forming a connection point G. Therefore, compared with the limited support points between the table legs and the table board in the prior art, this embodiment can add at least connection points C and D as new support points to achieve the distribution of the force on the table board 1, and the force is also more uniform.

[0027] More specifically, such as Figure 1 As shown, the first table leg group 2 and the second table leg group 3 each include two table legs and a connecting rod 23 connecting the two table legs. The two table legs of each group are the first table leg 21 and the second table leg 22 distributed horizontally in front and back, respectively. The connecting rod assembly 4 located on the front side corresponds to the first table leg 21 of the first table leg group 2 and the second table leg group 3, and the connecting rod assembly 4 located on the rear side corresponds to the second table leg 22 of the first table leg group 2 and the second table leg group 3.

[0028] By rotatably connecting the first table panel 11, the second table panel 12, and at least two table leg assemblies to the linkage mechanism, multiple support points are formed to distribute the force, thereby providing stable support for the table panel 1 when it is unfolded, while avoiding excessive concentration of force points.

[0029] Of course, in other embodiments, the number of table leg groups is not limited to this. Two relatively distributed table leg groups can be used as a table leg unit, and multiple table leg units can be arranged sequentially along the lateral direction of the tabletop 1 to match the different dimensions of the tabletop 1 in the lateral direction.

[0030] Furthermore, the number of linkage components 4 can also be one, that is, arranged on one side of the table 1 in the horizontal direction, but the number of support points will also be reduced accordingly.

[0031] In another preferred embodiment, such as Figure 1As shown, the specific table legs include a first leg tube 211, a second leg tube 212, and a locking assembly 213 disposed between the first leg tube 211 and the second leg tube 212. The second leg tube 212 can extend and retract relative to the first leg tube 211, and the locking assembly 213 enables stepless adjustment of the extension length between the first leg tube 211 and the second leg tube 212.

[0032] In specific implementation, the locking assembly 213 includes a connecting seat, a rack, an elastic reset member, and a rotatable rotating handle. The elastic reset member is a spring. The connecting seat is sleeved on the lower end of the first leg tube 211 facing the second leg tube 212. The rack is installed inside the second leg tube 212, and the second leg tube 212 is movably inserted through the connecting seat and inserted into the first leg tube 211. One end of the rotating handle has a protruding tooth. The middle part of the rotating handle is rotatably mounted on the connecting seat through a hinge shaft. An elastic reset member is provided between the end of the rotating handle away from the protruding tooth and the connecting seat. The connecting seat has a clearance groove to allow the protruding tooth to move. The elastic reset member applies a spring force to the other end of the rotating handle away from the protruding tooth so that the protruding tooth rotates toward the rack and can be separably engaged with the tooth groove of the rack.

[0033] Through the combined action of the rack, the elastic reset member, and the rotating handle, the elastic reset member applies a spring force to the other end of the rotating handle away from the convex tooth, so that the convex tooth can rotate toward the rack and can be separably engaged with the tooth groove of the rack. The rack has multiple continuously distributed tooth grooves to correspond to multiple adjustment positions for different table leg extension lengths, thereby realizing stepless adjustment of the extension length between the first leg tube 211 and the second leg tube 212.

[0034] By pressing the end of the rotating handle away from the convex tooth, the elastic force limitation of the elastic reset member is overcome, thereby unlocking the engagement between the rack and the convex tooth of the rotating handle. Therefore, this embodiment can unlock and lock the telescopic leg tube through a simple pressing action. Compared with the prior art, this embodiment can optimize the complexity and difficulty of operation, thereby quickly and conveniently realizing stepless adjustment of the telescopic length of the table legs, which can realize the increase or decrease or adjustment of any table height.

[0035] In addition, this embodiment adopts a table leg structure with adjustable support height, which can increase the comfort and portability of the folding chair, effectively improve the user experience, and ensure its use in multiple scenarios, especially maintaining stability in some complex terrains, and the overall structure has strong load-bearing capacity.

[0036] Further preferred, such as Figure 1 and Figure 2 As shown, the folding table also includes two elastic unfolding parts 5, which are the first elastic unfolding part and the second elastic unfolding part, respectively, and the specific elastic unfolding part 5 is a hydraulic rod, a gas spring or a pneumatic rod.

[0037] A first elastic unfolding member and a second elastic unfolding member are respectively provided between the connecting rod 23 of the first table panel 11 and the first table leg assembly 2, and between the connecting rod 23 of the second table panel 12 and the second table leg assembly 3. That is, one end of the first elastic unfolding member is rotatably connected to the first table panel 11, and the other end of the first elastic unfolding member is rotatably connected to the connecting rod 23 of the first table leg assembly 2. One end of the second elastic unfolding member is rotatably connected to the second table panel 12, and the other end of the second elastic unfolding member is rotatably connected to the connecting rod 23 of the second table leg assembly 3.

[0038] In this embodiment, with the cooperation of the linkage mechanism and relying on the elastic force of each elastic unfolding member 5 to drive the first table panel 11, the second table panel 12, the first table leg group 2, and the second table leg group 3 to unfold in a coordinated manner, the folding chair can be quickly and conveniently unfolded by pushing with the elastic force of each elastic unfolding member 5, so as to further enhance the user experience. Compared with similar products on the market, the folding chair of this embodiment has a more significant advantage in ease of use.

[0039] Also, when it is necessary to move the folding chair from such Figure 1 The unfolded state shown is switched to as follows: Figure 4 When in the folded state shown, it can be done as follows Figure 3 The half-fold state shown is switched to as follows: Figure 4 The folded state shown.

[0040] 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.
