Problems solved by technology

[0003] Most of the traditional screws are used with nuts or threaded grooves (holes). After the traditional screw fixings are installed, the vibration environment of the fixings is very easy to cause the screw and the nut to fall off, resulting in loosening of the fixings.

Abstract

The invention provides an anti-loosing screw rod. The anti-loosing screw rod comprises a hexagonal screw rod body, a hexagonal nut, a hexagonal nut cover, a plurality of fixing screw rod bodies, a first thread and a plurality of second threads. The hexagonal nut is arranged on the outer side of the hexagonal screw rod body in a sleeving mode, and the hexagonal screw rod body penetrates through thehexagonal nut. The hexagonal nut cover is arranged on the outer side of the hexagonal nut in a sleeving mode. The fixing screw rod bodies all penetrate through the hexagonal nut cover, and the fixingscrew rod bodies are in threaded connection with the hexagonal screw rod body. The first thread is formed on the outer side of the hexagonal screw rod body. The second threads are formed on the outersides of the fixing screw rod bodies respectively. The anti-loosing screw rod has the advantages of being convenient to use, easy to operate and capable of preventing the nut and the screw rod body from loosing.

Description

technical field [0001] The invention relates to the field of screw technology, in particular to an anti-loosening screw. Background technique [0002] The screw is a cylinder with a spiral groove cut on the outer surface or a cone cut with a spiral groove on the conical surface. The screw is divided into an outer hexagonal screw, a large flat screw, an inner hexagonal screw, and the like. [0003] Most of the traditional screws are used with nuts or threaded grooves (holes). After the traditional screw fixtures are installed, the vibration environment of the fixtures can easily cause the screws and nuts to fall off, resulting in loosening of the fixtures. [0004] Therefore, it is necessary to provide an anti-loosening screw to solve the above technical problems. Contents of the invention [0005] The technical problem solved by the invention is to provide an anti-loosening screw that is easy to use and easy to operate, and can prevent the nut and the screw from loosening...
