An anchoring device for expansion bolts used in building walls

Abstract

The invention discloses an expansion bolt anchoring device for a building wall. The device comprises a telescoping propping sleeve and a propping locking device, wherein the propping locking device comprises a locking nut, a propping ring plate, a connecting sleeve, a compressing gear and a handle rod; the propping ring plate is coaxially fixedly connected to the locking nut through the connectingsleeve; two symmetric compressing gear mounting lug platforms are arranged on the outer side surface of the propping ring plate, and the compressing gear is mounted on the compressing gear mounting lug platform through a rotating shaft; and an end head of the handle rod is connected to a tooth surface of the compressing gear. With the adoption of the device, an expansion bolt can be easily quickly mounted and fixed into a drilling hole, and an existing expansion bolt is not changed; and moreover, the operation is simple.

Description

technical field [0001] The invention relates to the technical field of building wall nails, in particular to an expansion bolt anchoring device for building walls. Background technique [0002] People will use expansion bolts when decorating houses and installing water and electricity. The existing commonly used expansion bolts, such as figure 1 As shown, the expansion bolt is generally composed of two parts, a movable expansion screw and a fixed expansion tube. Under the action of external force, the two parts are relatively movable, so that the fixed expansion tube is partially deformed and the volume becomes larger. , becomes larger than the inner diameter of the hole, thereby generating a locking force. During use, it often occurs that the diameter of the inner arm of the prefabricated hole is too much larger than the outer diameter of the expansion tube, and because the expansion tube of the expansion bolt and the inner wall of the prefabricated hole There is no large ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide an expansion bolt anchoring device for building walls, and solve the problem that the diameter of the inner arm of the prefabricated hole is too much larger than the outer diameter of the expansion tube during the use of the expansion bolt. , and because there is no frictional connection between the expansion tube of the expansion bolt and the inner wall of the prefabricated hole, and there is no interlocking connection between the expansion tube and the bolt, so that the expansion bolt rotates with the wrench during the tightening process and the nut cannot be screwed in. The problem that the expansion bolt cannot expand
