Multifunctional bolt

Abstract

The invention provides a multifunctional bolt. The multifunctional bolt comprises a first nut, a first screw rod, a first end cover, a second end cover, a second nut and a second screw rod. The firstend cover is mounted on the end face of the first end of the first nut. The second nut is mounted on the inner periphery of the first nut and is fixedly connected with the first end cover. The first end cover, the first nut and the second nut constitute a nested nut structure. The second end cover, the first screw rod and the second screw rod constitute a nested bolt structure. When the nested nutstructure and the nested bolt structure are connected, the first screw rod is in threaded connection with the first nut, the second screw rod is in threaded connection with the second nut, and a sliding block is inserted into a corresponding groove. The multifunctional bolt provided by the invention can prevent the first nut from getting loosened from the first screw rod under a threaded connection state, the connecting safety and reliability are guaranteed, and detachably connection of the first nut and the first screw rod is achieved; the problem that an existing fastener with the locking function cannot be dismounted is solved.

Description

Technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a multifunctional bolt. Background technique [0002] Bolts are commonly used fasteners in the mechanical field. They are indispensable in daily life and industrial production. Therefore, bolts are also known as the industrial meter, which shows that bolts are widely used. The bolt is locked with the nut during application. However, due to the rotation characteristics of the threaded connection, especially during the movement process, the nut has the risk of reverse rotation and detachment from the bolt. In response to this situation, a variety of anti-return bolts have appeared at present. However, these anti-return structures are all designed on the outer periphery of the bolts. Either the anti-return effect is not good, or the anti-return is unsafe, or the anti-return method is complicated to implement. Moreover, the existing anti-return structures are directly locked, so...

AI Technical Summary

Problems solved by technology

Cooperates with the nut for locking during bolt application, however, due to the rotational nature of the threaded connection, especially during movement, the nut runs the risk of being disengaged from the bolt by reverse rotation

In view of this situation, at present, there are many kinds of anti-retraction bolts, but these anti-retraction structures are all designed on the outer periphery of the bolts, either the anti-retraction effect is not good, or the anti-retraction is not safe, or the method of anti-retraction is complicated to implement.

Moreover, the existing anti-retraction structures are directly locked, so that the nut cannot be disassembled, which is not conducive to the maintenance and rework of the product.
