Description

Technical Field

[0001] The present invention relates to the technical field of folding tables, and particularly to a locking structure for folding tables.

Background Art

[0002] Folding tables can flexibly adjust the usage space and are easy to store and carry. As furniture products, they are widely used in various scenarios such as homes, offices, outdoor picnics, meetings, and exhibitions. Their main advantage is that with a foldable design, the space occupied by the table when not in use can be significantly reduced, improving the space utilization efficiency.

[0003] Conventional folding tables are generally tables hinged to each other. For example, the folding table disclosed in Publication No. CN205053216U realizes the folding of two table tops by using a set of integrally connected main components, so that the table can be folded and accommodated. However, after the folding table is unfolded, there is no mechanism for locking the connection between the two table tops. Therefore, when a collision occurs during use, relative rotation between the two table tops is likely to occur, and the structural stability is relatively poor.

[0004] The above content is for facilitating the understanding of the technical aspects of the present application and does not admit that the above content is the closest prior art to the present application.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Based on this, the present application provides a locking structure for a folding table to solve the above technical problems.

Means for Solving the Problems

[0006] This application adopts the following technical aspects. The locking structure for a folding table according to this application includes a first table board and a second table board, each provided with a first connection part and a second connection part. The first connection part and the second connection part, or the first table board and the second table board, are commonly hinged to an intermediate connection part and can be deployed or folded. The locking structure for a folding table is such that a first cavity is formed within the first connection part, and a second cavity is formed within the second connection part. When the first connection part and the second connection part are in the deployed state, the first cavity and the second cavity maintain a communicating state. Within the first cavity, a rotatable locking piece is provided that is rotated to maintain the locking of the first connection part and the second connection part in the deployed state and is simultaneously disposed within the first cavity and the second cavity.

[0007] In some embodiments, the first end portion of the locking piece is rotatably provided within the first connection part, and an operating member extending outside the first connection part is connected thereto. The operating member is used to rotate the locking piece.

[0008] In some embodiments, an internal hexagonal shaft hole is provided at the first end portion of the locking piece, and the operating member includes a knob disposed outside the first connection part and a hexagonal shaft inserted into the internal hexagonal shaft hole.

[0009] In some embodiments, a locking shaft is provided within the second cavity, and a locking hole is provided at the second end portion of the locking piece. When the locking piece rotates, the locking hole is locked to the locking shaft.

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

[0011] In some embodiments, the first connection part and the second connection part are each provided with a first abutting surface and a second abutting surface. When the first table board and the second table board are in the deployed state, the first abutting surface maintains abutment with the second abutting surface.

[0012] In some embodiments, the first connection part and the second connection part further include an insertion part. The first table board and the second table board have a hollow profile structure, are respectively inserted into the insertion part, fixed by a fastener, and commonly hinge-connected to the intermediate connection part.

[0013] In some embodiments, the first table board and the first connection part have an integral structure, the second table board and the second connection part have an integral structure, and the first connection part and the second connection part are commonly hinge-connected to the intermediate connection part.

Advantages of the Invention

[0014] The beneficial effects of the present application are as follows. The locking structure drives the rotation of the locking piece provided in the first cavity by an operating member provided in the first connection part, and rotates the locking piece into the second cavity on the second connection part, thereby realizing the locking in the unfolded state of the first table board and the second table board. Here, the locking hole on the locking piece fits with the locking shaft in the second cavity, so that when unlocking, a certain resistance is generated during the rotation of the operating member, effectively preventing the displacement of the locking piece caused by factors such as vibration during use. The present application is simple, practical, easy to operate, realizes the locking in the unfolded state of the folding table, and improves the stability of the folding table structure.

Embodiments for Carrying out the Invention

[0016] Hereinafter, the technical aspects of the embodiments of the present application will be clearly and completely described in conjunction with the drawings of the examples of the present application. Obviously, the described examples are only some examples of the present application, not all examples. Based on the examples in the present application, all other examples obtained by those skilled in the art without creative labor shall be included in the protection scope of the present application. Furthermore, the technical aspects between the embodiments can be combined with each other, but it must be based on the fact that it can be realized by those skilled in the art. When contradictions or impossibilities occur in the combination of technical aspects, such combinations of technical aspects do not exist and are considered not to be included within the protection scope of the present application.

[0017] In the embodiments of the present application, as shown in FIGS. 1 to 6, the locking structure for the folding table mainly includes a first table board 2 and a second table board 3 provided with a first connecting portion 4 and a second connecting portion 5 respectively. The first connecting portion 4 and the second connecting portion 5, or the first table board 2 and the second table board 3 are commonly hinged to an intermediate connecting portion 1 and can be deployed or folded. A first cavity 41 is formed in the first connecting portion 4, and a second cavity 51 is formed in the second connecting portion 5. When the first connecting portion 4 and the second connecting portion 5 are in a deployed state, the first cavity 41 and the second cavity 51 maintain a communicating state. In the first cavity 41, a rotatable locking piece 6 is provided which is rotated to maintain the locking of the first connecting portion 4 and the second connecting portion 5 in a deployed state and is disposed in the first cavity 41 and the second cavity 51 simultaneously. Here, in the case of a folded state, the locking piece 6 can be disposed only in the first cavity 41. When it is necessary to lock after deployment, the locking piece 6 is rotated to the second cavity 51, and at this time, the first connecting portion 4 and the second connecting portion 5 are simultaneously connected and the locked state is maintained.

[0018] Next, several preferred / improved embodiments based on the above embodiments will be continued to be described. Any of the following embodiments may be selected, or a plurality of embodiments may be selected and combined.

[0019] As shown in FIG. 2, the first end of the locking piece 6 is rotatably provided in the first connecting portion 4, and an operating member 7 extending outside the first connecting portion 4 is connected. The operating member 7 is used to rotate the locking piece 6. Here, the operating member 7 is provided below the first connecting portion 4.

[0020] As shown in FIGS. 4 to 5, a hexagonal socket hole is provided at the first end of the locking piece 6. The operating member 7 includes a knob 71 disposed outside the first connecting portion 4 and a hexagonal shaft 72 inserted into the hexagonal socket hole. In this way, when the operating member 7 rotates, the locking piece 6 can also deflect synchronously.

[0021] Furthermore, a locking shaft 8 is provided in the second cavity 51, a locking hole 61 is provided at the second end of the locking piece 6, and when the locking piece 6 rotates, the locking hole 61 is locked to the locking shaft 8. The opening direction of the locking hole 61 is inclined with respect to the width extending direction of the locking piece 6. After the locking hole 61 is locked to the locking shaft 8, a certain frictional force is generated between the locking piece 6 and the locking shaft 8. When the locking piece 6 is rotationally driven by the operating member 7, damping occurs, and it is prevented that the locking piece 6 is automatically displaced due to vibrations caused by factors such as collisions during locking.

[0022] 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 board 2 and the second table board 3 are in the unfolded state, the first abutting surface maintains abutment with the second abutting surface. In this way, the locking piece 6 can rotate without hindrance within the first cavity 41 or the second cavity 51.

[0023] Furthermore, the first connecting portion 4 and the second connecting portion 5 further include an insertion portion 9. The first table board 2 and the second table board 3 have a hollow profile structure, are respectively inserted into the insertion portion 9, fixed by a fastener, and are commonly hinge-connected to the intermediate connecting portion 1.

[0024] In some embodiments, the first table board 2 and the first connecting portion 4 have an integral structure, the second table board 3 and the second connecting portion 5 have an integral structure, and the first connecting portion 4 and the second connecting portion 5 are commonly hinge-connected to the intermediate connecting portion 1.

In order to avoid obscuring the concept of the present application, some details well known in the art are not described. Those skilled in the art can fully understand how to implement the technical aspects disclosed in this specification based on the above description.

[0026] Finally, the above are only preferred embodiments of the present application, and the above embodiments are only used for explaining the technical aspects of the present application, but are not limited thereto. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can change the technical aspects described in each of the above embodiments or equivalently replace some of the technical features. These changes or replacements do not deviate from the essence of the corresponding technical aspects from the spirit and scope of the technical aspects of each embodiment of the present application.
