Problems solved by technology

[0003] Most of the existing expansion bolts used on the floor are to insert the outer casing into the floor and then stretch the outer casing through the inserted inner bolts, so that the outer casing The body is plugged on the floor. Because the thickness of the floor is different and the hardness of the floor is different, when the thickness of the floor is thin, there are fewer contact points between the expanded area of ​​the outer shell and the floor, which will cause the floor to be unable to effectively align. The outer casing is stably fixed, so that the expansion bolts cannot effectively hang objects

Abstract

The invention relates to the field of bolts, in particular to an expansion bolt which comprises a bolt body assembly, an outer adjusting assembly and an inner adjusting assembly.Through outer adjusting assembly and the inner adjusting assembly which are arranged in the bolt main body assembly, an outer adjusting sleeve and an inner adjusting sleeve in the outer adjusting assembly and the inner adjusting assembly can drive a first sliding block and a second sliding block to slide in an adjusting groove, when the first sliding block and the second sliding block can slide, the distance between the first sliding block and the second sliding block can be adjusted through the outer adjusting sleeve and the inner adjusting sleeve, after the distance between the first sliding block and the second sliding block is changed, the included angle between a first expansion rod and a second expansion rod is changed, the first expansion rod and the second expansion rod extend outwards, a traditional expansion bolt supporting mode is replaced, the contact area between the outer shell and a floor can be effectively increased, and expansion bolt connection can be more stable.

Description

technical field [0001] The invention relates to the field of bolts, in particular to an expansion bolt. Background technique [0002] Expansion bolt is a special threaded connection used to fix pipeline supports / hangers / brackets or equipment on walls, floors, and columns. [0003] Most of the existing expansion bolts used on the floor are to insert the outer casing into the floor and then stretch the outer casing through the inserted inner bolt, so as to insert the outer casing on the floor. Because the thickness of the floor is different and the floor The hardness of the floor is different. When the thickness of the floor is thin, there are fewer contact points between the area where the outer shell is stretched and the floor, which will cause the floor to be unable to effectively fix the outer shell stably, so that the expansion bolts cannot effectively hang objects. . Contents of the invention [0004] Aiming at the problems in the prior art, the invention provides an...
