Problems solved by technology

[0003] Most of the current fixing bolts are composed of bolts and nuts. This kind of bolts and nuts are connected together by threaded connection. During the construction of construction projects, vibrations are often generated. Bolts and nuts do not have self-locking structures, which will be caused by vibrations. Loose, resulting in loose connection, serious safety accidents may occur

Abstract

A self-locking fixing bolt for construction engineering, relating to the technical field of construction engineering, including bolts, the inner walls on both sides of the bolt are fixedly connected with evenly distributed springs one, and the inner side of the spring one is fixedly connected with the inner wall of the bolt. limit rod. The construction project uses a self-locking fixed bolt, which is used in conjunction with the rotating rod and the limit rod. In the initial state, the limit rod shrinks into the bolt under the action of the spring one. After the fixed bolt is fixed and connected, it is rotated by the tool. Rotating rod, the rotating rod pushes out the telescopic rod to the outside through the turning slot, and the telescopic rod pushes out the ejector rod to the outside, the ejector rod pushes out the limit rod and engages with the limit slot in the nut, and the limit rod It is clamped with the inner wall of the fixed object to increase the fixed diameter, so as to achieve the effect of anti-loosening, increase the contact area, increase the friction force, and the clamping of the limit rod and the limit groove can effectively prevent the bolt and nut from falling off, effectively prevent loosening.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a self-locking fixing bolt for construction engineering. Background technique [0002] Fixing bolts are frequently used fixing devices in construction projects. Usually, two items are fixed and connected together by fixing bolts, so that the two items are integrated into a whole, which can withstand greater force and ensure the smoothness of the construction process. Safety. [0003] Most of the current fixing bolts are composed of bolts and nuts. This kind of bolts and nuts are connected together by threaded connection. During the construction of construction projects, vibrations are often generated. Bolts and nuts do not have self-locking structures, which will be caused by vibrations. Loose, resulting in loose connection, serious safety accidents may occur. [0004] Therefore, we propose a self-locking fixing bolt for construction engineering to solve the ab...
