Embodiment Construction

[0029] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0030] see Figure 1 to Figure 5 , an expansion plug of the present invention, comprising a first hollow cylinder 1, a second hollow cylinder 2 and a third body 3 connected in sequence, the third body 3 is provided with a notch 31, and the notch 31 is arranged along the third The length direction of the main body 3 is arranged, and the external connecting parts pass through the first hollow cylinder 1, the second hollow cylindrical body 2 and the gap 31 in sequence. Preferably, the external connecting parts protrude from the free end of the third main body 3;

[0031] The first hollow cylinder 1 is provided with several reinforcing ribs 11, and the several reinforcing ribs 11 form a...

Abstract

The invention relates to the technical field of wall body connecting parts, in particular to an expansion bolt. The expansion bolt comprises a first hollow column body, a second hollow column body anda third body, all of which are sequentially connected. The third body is provided with a notch, and an external connecting part sequentially penetrates through the first hollow column body, the second hollow column body and the notch. The first hollow column body is provided with reinforcing ribs, the second hollow column body is provided with at least one reinforcing assembly, the reinforcing assemblies comprise first connecting strips and second connecting strips, triangles are formed between the first connecting strips, the second connecting strips and the wall body of the second hollow column body, and the first connecting strips and the second connecting strips are flexible glue parts. As the reinforcing ribs are arranged on the wall body of the expansion bolt, the resistance of theexpansion bolt in a wall body is improved, and the expansion bolt is prevented from rotating in the wall body at will; and through the arrangement of the reinforcing assemblies, binding force of the expansion bolt and the wall body is improved, the stability of the expansion bolt in the wall body is improved, connecting force of the expansion bolt as a connecting part is improved, and the expansion bolt is suitable for being used for various wall bodies.

Description

technical field [0001] The invention relates to the technical field of wall connectors, in particular to an expansion bolt. Background technique [0002] In the field of building decoration, expansion bolts are widely used as the main connector, but there will be walls made of different materials in the building of the same unit, such as soft substrates made of new materials such as hollow bricks, high-pore bricks, and sand-lime bricks. Walls are hard substrate walls built with solid bricks, reinforced concrete, etc. There are various specifications of expansion bolts on the market to match walls with different substrates, but it also brings inconvenience to purchasers and users, because Many people cannot correctly judge which wall to use which specification of expansion bolts, the expansion bolts cannot be used correctly, and the connection force cannot reach the expected effect. Contents of the invention [0003] In order to overcome the disadvantages in the prior art ...
