[0023] In the description of the utility model, it is understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end", "length", "outer end" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0024] The utility model will be further described below in combination with the drawings.

[0025] As shown in Figure 1 and 2 , a desktop hidden hinge 2 and a table, comprising table board main body 1 and hidden hinge 2. Wherein, table board main body 1 includes two table top panels. The adjacent side edges of the two table top panels are provided with two embedded recesses matched with the hidden hinge 2. Two hidden hinges 2 are embedded in the two embedded recesses, for connecting the two table top panels, so that the two table top panels can realize relative folding and unfolding.

[0026] As shown in Figure 2 , the hidden hinge 2 includes a connecting piece 2-1 and two leaf body 2-2. Wherein, two leaf body 2-2 is hingedly arranged on both sides of connecting piece 2-1, and leaf body 2-2 rotates around connecting piece 2-1 to realize the switching of the folding state and the unfolding state of the desktop hidden hinge 2. The adjacent side edges of the two leaf body 2-2 are provided with notches. Two notches are communicated with each other to form an installation recess 3 matched with the connecting piece 2-1. The connecting piece 2-1 is arranged in the installation recess 3 and is hingedly arranged with the two leaf body 2-2.

[0027] Specific structure is that the first installation hole is arranged on both sides of connecting piece 2-1. The leaf body 2-2 is provided with a guide hole communicated with the corresponding first installation hole, and a hinge shaft is inserted and arranged in the guide hole and the first installation hole.

[0028] Further, the hinge shaft adopts a pin. The leaf body 2-2 is divided into a connecting part on the outer side and an embedded part on the inner side. Wherein, the embedded part is in the shape of a mouth. The corner of the embedded part in the shape of a mouth is provided with a shaft sleeve 4. The shaft sleeve 4 is provided with a C-shaped notch communicated with the guide hole. When assembling, the pin passes through the guide hole and the first installation hole in sequence, so as to complete the hinge connection between the connecting piece 2-1 and the corresponding leaf body 2-2. By setting the structure in the shape of a mouth on the connecting piece 2-1 and the outer circle of the pin, the strength of the hinge connection part can be effectively increased.

[0029] In the embodiment, the sheet body 2-2 is made of aluminum profile. The top surface of the connecting piece 2-1 is flush with the top surface of the sheet body 2-2, which can effectively avoid the exposure of the connecting piece 2-1.

[0030] Further, the two desktop panels are provided with second installation holes communicated with the corresponding embedded recesses. When assembling, the two desktop panels are connected and aligned in an unfolded state. The hinge bodies in the hidden hinges 2 are sequentially placed in the embedded recesses. The connecting piece 2-1 is placed in the slot between the two hinge bodies. The pin is inserted from the second installation hole on the desktop panel and sequentially passes through the guide hole on the hinge body and the first installation hole on the connecting piece 2-1, thereby completing the assembly.

[0031] As shown in Figure 3 When the two desktop panels are folded, the two sheet bodies 2-2 rotate 90° around the corresponding pins, and the bottom surface of the connecting piece 2-1 is flush with the inner side surfaces of the two sheet bodies 2-2, which eliminates the safety hazard of scratching the user caused by the partial protrusion of the sheet body 2-2 when the two desktop panels are folded.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
