Description

[Technical Field]

[0001] The present invention relates to the field of folding table manufacturing technology, and more particularly to the structure of a folding table. [Background technology]

[0002] In recent years, outdoor camping has become increasingly popular, and portable tables and chairs are often used when camping. To ensure portability, typical portable tables mainly adopt two types. The first type is a disassembly and assembly structure, in which the tabletop and table legs are disassembled for transport and then reassembled when needed. However, this method requires time and effort for disassembly and assembly. The second type is a foldable structure, in which the table legs are folded for storage, reducing the volume during transport. For example, Chinese patent application numbers CN201620401338.8 and CN202221501530.0 disclose folding table structures. These structures feature foldable table legs and a bifoldable tabletop. However, the folding operation requires first folding the table legs and then folding the tabletop in half. To open the tabletop, the reverse procedure must be followed, i.e., first unfolding the tabletop and then unfolding the table legs, which is cumbersome. More importantly, when folding the tabletop in half, gravity can cause the table legs to unfold, potentially interfering with the folding process. Therefore, conventional folding table structures have room for improvement. Summary of the Invention

[0003] SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems and to provide a folding table structure that has a rational structure and allows the table top and table legs to be unfolded and retracted synchronously.

[0004] The technical means of the present invention are as follows: The folding table structure of this invention includes two hinged tabletops, each of which has two table leg assemblies attached to its inner surface. Each table leg assembly includes a mounting base and a rotating shaft. The mounting base is fixed to the tabletop, and the rotating shaft is rotatably fitted to the mounting base. The rotating shaft has a table leg member attached to its outer end and a connecting block attached to its inner end. Corresponding connecting blocks on the two tabletops are hinged to each other, and the corresponding rotating shafts form an obtuse angle. Preferably, the table leg unit includes a support block, the support block being provided with a support surface for positioning and supporting the table leg member. Preferably, the support surface is formed to be inclined outward. The support surfaces on the support blocks position and support the table leg members when the table leg units are deployed, increasing the support strength of the table leg members. In addition, by slanting the support surfaces outward, the table leg members are forced to swing outward when deployed, increasing support stability. Preferably, a magnetic material is embedded in the support block, and when the tabletop is folded, magnetic attraction prevents the tabletop from opening unintentionally. Preferably, the table leg member can be configured to be connected to the rotary shaft via an elbow member, and can also be molded integrally with the rotary shaft. Preferably, the table tops are connected to each other by hinges, the hinges being provided on the inner surfaces of the table tops, so that the table tops are joined together without any gaps when unfolded. Preferably, the hinge includes a hinge seat and a hinge shaft, and the hinge seat is formed integrally with the table top plate, thereby improving assembly efficiency and assembly accuracy. Preferably, the tabletop includes a surface layer and a honeycomb layer, the surface layer ensuring the flatness of the surface of the tabletop, and the honeycomb layer realizing a reduction in weight of the tabletop while maintaining its strength. Preferably, the table top plate is provided with a rim member on its outer periphery. Preferably, the table leg members are provided with rubber legs at their ends.

[0005] Compared with the prior art, the advantages of the present invention are as follows: The folding table structure of this invention is rational and includes two hinged tabletops, with a table leg assembly attached to the inside of the tabletop. The connecting blocks of the corresponding table leg assemblies are hinged together, and the corresponding rotation axes on the two tabletops form an obtuse angle. With this design, when the tabletop is folded, the rotation axis rotates, allowing the table legs to rotate and fit into place, allowing both the tabletop and legs to be stored simultaneously. Conversely, when the tabletop is opened, the legs unfold, greatly improving the convenience and safety of folding and unfolding. [Brief explanation of the drawings]

[0007] The present invention will be explained in more detail below with reference to the drawings. The following description is intended to disclose the present invention and enable those skilled in the art to practice the present invention. The preferred embodiments described below are merely examples, and it is clear that other obvious modifications may be conceived by those skilled in the art.

These terms do not imply or limit the subject devices or components to have a particular orientation, or to be configured or operate in a particular orientation. Therefore, these terms should not be construed as limitations on the present invention. Furthermore, the term "one" means "at least one" or "one or more" and does not imply a quantitative limitation, i.e., the number of components may be one in some embodiments, while the number may be multiple in other embodiments.

[0008] As shown in Figures 1 to 6, the folding table structure of the present invention includes two hinged tabletops 1, with two sets of table leg units mounted inside each tabletop 1. The table leg units include a mounting base 2 and a rotating shaft 3, with the mounting base 2 fixed to the tabletop 1 and the rotating shaft 3 rotatably fitted to the mounting base 2. A table leg member 31 is mounted on the outer end of the rotating shaft 3, and a connecting block 32 is mounted on the inner end. Corresponding connecting blocks 32 on the two tabletops 1 are hinged to each other, and the angle between the corresponding rotating shafts 3 is an obtuse angle. In this embodiment, two corresponding connecting blocks 32 are hingedly connected by a hinge 7 . Furthermore, the table leg unit includes a support block 4, and the support block 4 is provided with a support surface 4a for positioning and supporting the table leg member 31. The support surface 4a is formed to be inclined outward. The support surfaces 4a on the support blocks 4 can position and support the table leg members 31 when the table leg units are unfolded, thereby increasing the support strength of the table leg members 31. In addition, by inclining the support surfaces 4a outward, the table leg members 31 are caused to open outward when unfolded, thereby increasing support stability. Furthermore, a magnetic material is embedded in the support block 4, and when the table top 1 is folded, it is attracted by magnetic force to prevent it from opening unintentionally. The rotary shaft 3 is provided so as to penetrate the support block 4, and the two are connected by a rotatable fitting, thereby increasing the mounting reliability of the rotary shaft 3. The table leg member 31 can be configured to be connected to the rotary shaft 3 via an elbow member 5, which contributes to facilitating the assembly work. It is also possible to form the table leg member 31 by molding it integrally with the rotary shaft 3 and bending the end portion thereof. Furthermore, the table top plates 1 are interconnected by hinges 6, which are provided on the inner surfaces of the table top plates 1. With this configuration, the table top plates 1 are joined together without any gaps when unfolded, ensuring the integrity of the table top. The hinge 6 includes a hinge seat 61 and a hinge shaft 62, and the hinge seat 61 is formed integrally with the table top plate 1. This can improve assembly efficiency and assembly accuracy. The tabletop 1 also includes a surface layer 11 and a honeycomb layer 12. The surface layer 11 forms an integral plate surface, which ensures the flatness of the surface of the tabletop 1. On the other hand, the honeycomb layer 12 makes the tabletop 1 lighter while maintaining its strength. A rim member 13 is provided on the outer periphery of the table top plate 1, and covers the inner honeycomb layer 12 to improve the appearance. Furthermore, the end of the table leg member 31 is provided with a leg rubber 31a.

[0009] Working principle: As shown in FIG. 5, when the tabletop 1 is folded, the angle between the rotation axes 3 of the corresponding table leg units on the two tabletops 1 is an obtuse angle. Therefore, as the tabletop 1 folds, the connecting blocks 32 rotate inward, rotating the rotation axes 3. The rotation axes 3 then rotate the table leg members 31, allowing them to be retracted. In this way, the leg members 31 are also retracted simultaneously with the folding of the tabletop 1. As shown in FIG. 6, when the folding table of this invention is in the retracted state, each table leg unit is housed between the two tabletops 1. Conversely, when the tabletop 1 is unfolded, the connecting blocks 32 rotate under pressure, causing the rotation axes 3 to rotate, which then rotate the table leg members 31, allowing them to be unfolded. As the two tabletops 1 unfold 180°, the table leg members 31 are positioned and supported by the support surfaces 4a of the support blocks 4. In this way, the folding table of the present invention allows the tabletop 1 and table legs 31 to be folded and unfolded simultaneously, greatly improving the convenience of folding and unfolding. In addition, the table legs 31 and tabletop 1 are interlocked with each other, which also improves safety.

The objectives of the present invention have been fully and effectively achieved. The function and structural principles of the present invention have been shown and explained in the examples, and any variations or modifications can be made to the embodiments of the present invention without departing from these principles.
