Problems solved by technology

However, although this invention can be applied to the situation where the base plate is relatively thick and can only be fastened by counterbore holes, because the self-locking effect is achieved by screwing the inner screw into the tapered hole of the outer screw to deform the outer thread, it is often Problems that can make disassembly difficult and make the bolt unusable after removal

Abstract

A detachable anti-loosening bolt, comprising: a main bolt, an auxiliary stud, an inner top screw and an anti-loosening positioning device; the auxiliary stud is connected to a threaded hole on a base plate, and the main bolt passes through the assembly hole of the assembly plate The threaded holes on the base plate are connected; the inner top screw passes through the main bolt to connect with the auxiliary stud, and the anti-loosening positioning device is arranged in the inner top screw; the present invention installs the main bolt and the auxiliary stud into the base plate, and the inner The top screw passes through the main bolt and the auxiliary stud is reversely threaded to realize the fastening and self-locking of the bolt, which is not only suitable for the case where the base plate is thick and can only be fastened by counterbore, but also can be disassembled repeatedly Utilization can effectively reduce the cost of use and improve the application breadth.

Description

technical field [0001] The invention relates to the technical field of mechanical fastening parts, in particular to a split-type anti-loosening bolt. Background technique [0002] The bolt is used to fasten and connect two mechanical parts that need to be fixed. If the bolt is unscrewed, the two parts can be separated. Therefore, the bolt connection is a detachable connection and is widely used in the connection of multiple plates. When the mechanical equipment is running, mechanical vibration will inevitably occur. Long-term mechanical vibration will cause the bolt to shake and lead to thread wear, which will make the tightening effect of the bolt worse, affecting the working performance and stability of the mechanical equipment, especially affecting some The machining accuracy of precision equipment may also cause the bolt to come out of the threaded hole, resulting in mechanical failure. [0003] At present, the bolts on the market do not have an automatic anti-loosening...
