Fig. 1 to 2 are schematic structural views illustrating a table connecting device according to an embodiment of the present invention applied to a table. The connecting device of the table is used for connecting the first supporting piece and the second supporting piece. The following description will be made with reference to the embodiment in which the first supporting member is a table leg and the second supporting member is a cross member, but the invention is not limited thereto. In some embodiments, the first support member is a cross member and the second support member is a table leg. In other embodiments, the first supporting member and the second supporting member are both plate-type structures or any combination of plate-type structures with the table legs and the cross beams, which will not be described herein. In the embodiment, the table legs 2, the cross beams and the longitudinal beams jointly form a support of the table, and the support of the table and the table top can form the table. In this embodiment, the number and positions of the table legs 2 and the cross beams 3 are only examples, and in practical applications, other different table support structures may be adopted, without being limited to those shown in fig. 1 to 2.

The structure of the connecting device provided by the invention can be seen in fig. 3-11. The connecting device comprises a connecting device body 4, a first fastening member and a decorative cover 1.

The two ends of the connecting device body 4 are respectively connected with the table legs 2 and the cross beam 3, and the connecting device body 4 is provided with a through hole 41. One end of the through hole 41 of the connecting device body 4, which faces away from the table leg 2, is provided with a second groove 51 for accommodating the decorative cover 1 and a third groove 55 for accommodating the first fastening member.

The first fastener is positioned in the through hole 41 and connects and fixes the connecting device body 4 and the table leg 2. The first fastener is often a vertical connector in view of ease of installation and removal.

In this embodiment, the first fastener is preferably a first screw 52. The first connection hole 23 is a threaded hole corresponding to the first screw 52, and a head 521 of the first screw 52, which can be magnetically attracted, is located in the third groove 55. Therefore, the head 521 of the first screw 52 is not protruded out of the connecting device body 4, and the second end of the first screw 52 is fixed in the first connecting hole 23 provided in the table leg 2, which has the effect of hiding the first screw 52. The first recess is preferably a circular recess and the first screw 52 is preferably an interior angle screw and further preferably a socket head cap screw. When the inner angle screw is adopted, a dismounting tool, such as an inner hexagonal wrench, can be conveniently placed at the head of the inner angle screw, and the table legs 2 and the connecting device body 4 are conveniently mounted and dismounted.

In practical applications, the first fastening member may also be other types of fastening members, such as an external angle screw having a head that can be attracted magnetically, a connecting pin, etc., and the present disclosure is only given as a preferred embodiment, and the scope of the present disclosure is not limited thereto.

The cosmetic cover 1 covers the through hole 41. In the present embodiment, the cosmetic cover 1 is accommodated in the second recess 51 of the connecting device body 4. The inner diameter of the second groove 51 is larger than the inner diameter of the through-hole 41 of the connecting device body 4 so that the cosmetic cover 1 does not fall through the through-hole 41. The outer contour of the trim cover 1 may be adapted to the inner contour of the second recess 51 and the second side of the trim cover 1 may be flush with the top surface of the second recess 51 to achieve an indirect appearance of the connecting device.

The first side is provided with a magnetic member 12 for magnetically attracting the first fastening member. The magnetic member 12 may be a permanent magnetic cylinder. In this embodiment, the first side surface of the decoration cover 1 is provided with a convex portion 11, the convex portion 11 is provided with a concave portion opened to the second side surface, and the magnetic member 12 is embedded in the concave portion. Alternatively, the magnetic member 12 may be embedded in the recess by interference fit. A gap is provided between the top surface of the convex portion 11 of the first side surface of the trim cover 1 and the top surface of the first fastening member. The second side of the trim cover 1 is provided with a first recess 13. The first recess 13 corresponds to the position of the magnetic member 12 for the external member 7 to magnetically attract the magnetic member 12. The attraction force of the decoration cover 1 after assembly is controlled by setting the distance between the magnetic member 52 and the first groove 13 of the top end of the decoration cover 1. It is preferable that the distance between the bottom wall of the first recess 13 and the magnetic member 12 is smaller than the distance between the magnetic member 12 and the first fastening member in the axial direction of the through hole 41.

In normal use, the decorative cover 1 is fixed in the second groove 51 by the magnetic force generated by the magnetic member 12 and the first screw 52 installed inside the decorative cover; during disassembly, because of the distance, the disassembly tool is arranged in the first groove 13 formed in the top of the decorative cover 1, and the magnetic force generated between the disassembly tool and the magnetic part 12 is greater than the magnetic force between the first screw 52 and the magnetic part 12, so that the decorative cover 1 is disassembled.

The decorative cover 1 is fixed by the magnetic part 12, and the decorative cover 1 is mounted and dismounted by adjusting the distance between the magnetic part 12 and the first groove 13. Compare the interference fit push-in formula dress trim cover that adopts usually among the prior art, it is more convenient to dismantle to connect more firmly.

Further, in this embodiment, the connecting means may further comprise a first boss 5 and a second boss 6.
