Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Examples

Referring to fig. 1, the invisible connecting piece for panel furniture in the embodiment includes an embedded sleeve 1 made of an alloy material through die casting and a connecting rod 2 made of an iron-plastic material through combination.

As shown in fig. 1 and 2, the whole connecting rod 2 is cylindrical, the top end of the connecting rod is provided with a notch 22, the top ends of the two side walls of the notch 22 are respectively provided with a conical head 21, the two conical heads 21 are symmetrical to each other, and due to the design of the notch 22, the two conical heads 21 can be contracted and expanded. Meanwhile, the front end and the rear end of the conical head 21 are provided with certain conicity, and the conicity of the front end and the rear end are different in size, so that the special requirement that the plate-type furniture can be assembled and disassembled is met, the plate-type furniture is easy to enter and difficult to exit, and the requirement for increasing the combination strength is met. During assembly, the conical head 21 of the connecting rod 2 penetrates from the bottom opening of the embedded sleeve 1, and is respectively clamped on the top opening of the embedded sleeve 1 in an outward expansion mode after penetrating out from the top opening of the embedded sleeve 1, and the tail portion of the connecting rod 2 is exposed outside the embedded sleeve 1.

As shown in fig. 1 and 2, an annular positioning piece 24 is arranged between the main body of the connecting rod 2 and the tail exposed outside the embedded sleeve 1. The positioning plate 24 not only ensures the installation precision, but also reduces the installation difficulty. As shown in fig. 1, 3 and 4, a positioning cap 14 corresponding to a positioning sheet 24 is arranged at a bottom opening of the embedded sleeve 1, and a counter bore 15 for accommodating and hiding the positioning sheet 24 is arranged in the positioning cap 14; after assembly, the locating tab 24 is received in the counterbore 15 to ensure tightness of the installation.
