Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fastener, concretely is a bolt with the function of auxiliary restriction nut rotation. BACKGROUND

[0002] The bolt is a cylindrical threaded fastener connected with two or more components and a nut, and is widely used in various industrial equipment and daily life. For example, in the automobile, construction, railway, and bridge industries, the bolt is an important tool for connecting and fixing various components. When installing the bolt, a screwdriver or wrench is often used to assist in the installation.

[0003] A double-hexagonal bolt head bolt is disclosed in Chinese Patent No. CN212155400U, which includes a bolt body, a first bolt head fixed to the bolt body, and a second bolt head fixed to the sidewall of the first bolt head. The utility model pushes the limiting rod of the fixed block sidewall to extrude the bolt body through the elastic force of the pressure spring, fastens the nut to the outer sidewall of the bolt body, and further prevents the nut from detaching from the bolt body when vibrating by engaging the sawtooth-shaped limiting rod sidewall in the thread groove of the bolt body. By pushing the push rod, the push rod slides in the direction of the limiting rod, the fixed block slides away from the bolt body, the pressure spring contracts to generate elastic force, and the limiting rod slides away from the bolt body. At this time, the bolt body can be rotated to move inside the nut for fastening the object. By stopping pushing the push rod, the fixed block and the limiting rod are reset by the elastic force of the pressure spring, the limiting rod extrudes the bolt body again, and the bolt body and the nut are fixed to the object for fastening.

[0004] However, in the prior art, when using the bolt in a place with strong vibration, the nut and the bolt may rotate relative to each other after long-term use of the bolt, which needs to be further improved.

[0005] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a bolt with auxiliary nut rotation limiting function. UTILITY MODEL CONTENTS
