Problems solved by technology

[0002] Existing bolt pairs usually include bolts, nuts and washers. Their specific structures and usage methods are traditionally known and common in daily life. They will not be described in detail here. You can find relevant ones by searching for bolt pairs on the Internet. Information picture, the structure of ordinary bolt pair has basically no structural improvement since it was used as a fastener. The production requirements for ordinary bolt pair are the basic material, structural strength, and accuracy requirements, while the fastening and anti-loosening The requirement for the effect is basically to achieve the problem of fastening and anti-loosening by using elastic washers, anti-loosening washers or double nuts. The inventor of this case also conducted in-depth research on the problem of fastening and anti-loosening, so this case came into being.

Abstract

The invention discloses an enclasping type anti-loosening bolt pair. The enclasping type anti-loosening bolt pair comprises a bolt and a nut. The bolt comprises a bolt head and a bolt rod, wherein thebolt head is of an integral structure, and the bolt rod is provided with an external thread which extends to the tail end. The nut is in threaded fit with the bolt rod. The nut comprises a nut body and an enclasping mechanism, wherein the enclasping mechanism is arranged on one end face of the nut body and can be adjusted to enclasp the bolt rod. According to the bolt pair of the structure, afterthe nut is in threaded fit with the bolt rod and fastened, the bolt rod can be enclasped by adjusting the enclasping mechanism, and the nut is not easy to loosen; and the anti-loosening effect is obvious.
