Problems solved by technology

However, in actual work, the equipment is often subjected to loads such as alternating loads and impact loads, and the vibration generated by it is much larger than the expected vibration. The current solution does not have a satisfactory anti-loosening effect, and there are still complex structures. , high production cost, inconvenient installation, etc.

Abstract

The invention provides a bolt locking structure, and belongs to the technical field of fasteners. The bolt locking structure comprises a first bolt, a nut in threaded fit with the first bolt and a second bolt. A threaded hole in threaded fit with the second bolt is formed at the screw tail end of the first bolt. The thread turning directions of the second bolt and the first bolt are opposite. Thefirst bolt sequentially penetrates through two to-be-fastened workpieces. The nut and the first bolt are screwed from the opposite side, and the second bolt is screwed into the threaded hole from theopposite side so as to fasten the two to-be-fastened workpieces. The thread turning directions of the first bolt and the second bolt are opposite, and therefore the first bolt and the second bolt restrain each other to achieve the anti-loose locking aim.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a bolt locking structure. Background technique [0002] Bolt is a commonly used fastener, which is widely used in various mechanical equipment. The working environment of many equipment and parts is harsh, and they are in a vibrating working environment for a long time, so that the bolts used to fasten the equipment and parts are easy to loosen, which affects the normal operation of the equipment and parts, causing major economic losses, and even causing serious economic losses. become a safety accident. [0003] In order to solve the problem of bolt loosening, there are various solutions such as lock nuts and gaskets, for example, the authorized patent CN105864265B is one of the solutions. However, in actual work, the equipment is often subjected to loads such as alternating loads and impact loads, and the vibration generated by it is much larger than the expected vibration....
