Description

Technical Field

[0001] The present application relates to the technical field of folding tables, and in particular to a locking structure of a folding table. Background Art

[0002] Folding tables, as a furniture product that can flexibly adjust the use space and is easy to store and carry, are widely used in various occasions such as home, office, outdoor picnic, conference and exhibition. Its core advantage lies in the folding design, which greatly reduces the space occupied by the desktop when not in use, thereby improving space utilization efficiency.

[0003] Existing folding tables generally have table tops that are hinged to each other, such as the folding table disclosed in announcement number CN205053216U, which uses a set of integral connecting main parts to realize the folding of the two table tops, thereby realizing the folding and storage of the table. However, there is a lack of a connecting and locking mechanism between the two table tops after the folding table is unfolded. As a result, when the folding table is used and encounters an impact, the two table tops are prone to relative rotation, and the structural stability is relatively poor.

[0010] In some embodiments, the opening direction of the locking hole is inclined relative to the width extension direction of the locking piece.

[0011] In some embodiments, the first connecting portion and the second connecting portion are respectively provided with a first abutting surface and a second abutting surface. When the first table top and the second table top are in the unfolded state, the first abutting surface and the second abutting surface remain in abutment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0024] In the examples of this application, please refer to Figure 1-6As shown, the locking structure of the folding table mainly includes: a first table board 2 and a second table board 3, and the first table board 2 and the second table board 3 are respectively provided with a first connecting part 4 and a second connecting part 5; the first connecting part 4 and the second connecting part 5 or the first table board 2 and the second table board 3 are hinged together on an intermediate connecting part 1, and the two can be unfolded or folded; a first cavity 41 is formed in the first connecting part 4, and a second cavity 51 is formed in the second connecting part 5; when the first connecting part 4 and the second connecting part 5 are in the unfolded state, the first cavity 41 and the second cavity 51 remain in communication; a rotatable locking piece 6 is provided in the first cavity 41, and the locking piece 6 can be rotated and placed in the first cavity 41 and the second cavity 51 at the same time to keep the first connecting part 4 and the second connecting part 5 locked when they are in the unfolded state, wherein, in the folded state, the locking piece 6 can only be placed in the first cavity 41, and when locking is required after unfolding, the locking piece 6 is rotated to the second cavity 51, and at this time, the first connecting part 4 and the second connecting part 5 are connected at the same time, thereby maintaining the locking.

[0025] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0026] like Figure 2 As shown, the first end of the locking piece 6 is rotatably arranged in the first connecting part 4, and is connected to an operating member 7 extending to the outside of the first connecting part 4, and the operating member 7 is used to drive the locking piece 6 to rotate, wherein the operating member 7 is arranged below the first connecting part 4.

[0027] like Figure 4-5 As shown, the first end of the locking piece 6 is provided with an inner hexagonal shaft hole, and the operating member 7 includes a knob 71 and a hexagonal shaft 72. The knob 71 is placed outside the first connecting part 4, and the hexagonal shaft 72 is inserted into the inner hexagonal shaft hole. In this way, when the operating member 7 is rotated, the locking piece 6 can be deflected synchronously.

[0028] Furthermore, a locking shaft 8 is provided in the second cavity 51, and a locking hole 61 is provided at the second end of the locking piece 6. After the locking piece 6 is rotated, the locking hole 61 is locked on the locking shaft 8. The opening direction of the locking hole 61 is inclined relative to the width extension direction of the locking piece 6, ensuring that after the locking hole 61 is in contact with the locking shaft 8, there is a certain friction between the locking piece 6 and the locking shaft 8, so that there is damping when the operating part 7 is used to drive the locking piece 6 to rotate, and when locked, the locking piece 6 is prevented from automatically deflecting due to vibration due to collision and other factors.

[0029] Specifically, the first connecting portion 4 and the second connecting portion 5 are respectively provided with a first abutting surface 42 and a second abutting surface 52. When the first table top 2 and the second table top 3 are in the unfolded state, the first abutting surface and the second abutting surface remain in abutment, and the locking piece 6 can rotate unimpeded in the first cavity 41 or the second cavity 51.

[0030] Furthermore, the first connecting portion 4 and the second connecting portion 5 also include a plug-in portion 9. The first table top 2 and the second table top 3 are hollow profile structures, which are respectively plugged into the plug-in portion 9 and fixed by fasteners. The first table top 2 and the second table top 3 are jointly hinged to the middle connecting portion 1.

[0031] In some embodiments, the first table top 2 and the first connecting portion 4 are an integral structure, the second table top 3 and the second connecting portion 5 are an integral structure, and the first connecting portion 4 and the second connecting portion 5 are hinged together on the middle connecting portion 1 .

[0032] Thus far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
