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

The invention provides a split type locking bolt. The locking bolt comprises a main bolt, an auxiliary stud, an inner jacking screw and a locking positioning device. The auxiliary stud is connected with a threaded hole in a base plate; the main bolt penetrates through an assembling hole in an assembling plate to be connected with the threaded hole in the base plate; the inner jacking screw penetrates through the main bolt to be connected with the auxiliary stud; and the locking positioning device is arranged in the inner jacking screw. Fastening and self-locking of the bolt are achieved in themode that the main bolt and the auxiliary stud are installed in the base plate and the inner jacking screw penetrates through the main bolt to be in reverse threaded connection with the auxiliary stud, the bolt can be applied to the situation that the base plate is thick and can only be fastened through a counter bore, repeated dismounting, mounting and utilization can be achieved, the using costis effectively reduced, the practicability is high, and the wideness of application is improved.

Description

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