Problems solved by technology

[0002] Nuts are common fasteners. Traditional nuts generally do not have an anti-loosening function. Since many bolts and nuts are used on machines, after starting the machine, the machine will vibrate a little. Therefore, when the bolts and nuts have been used for a long time , the nuts will loosen or even break away from the bolts, which will have an important impact on the normal operation of the machine

Abstract

The invention discloses a nut with a good anti-loose effect. The nut comprises a hexagon nut part, an anti-loose part, an inested spring, a limiting step, a rotating external member, a rotating shaft and a rotating handle. The inested spring is installed in the anti-loose part. The anti-loose part is provided with a spring extending opening, a spring fixing opening and a center hole. The inested spring comprises a spring fixing end, a spring extending end and a spring ring part. The spring fixing end is fixed into the spring fixing opening. The spring extending end extends out of the spring extending opening. According to the nut, the inested spring ring is additionally arranged on the nut, thus, the situation that due to long-time machine vibration to a bolt and the nut, the nut loose can be effectively prevented, and then the anti-loose effect of the nut is improved. The rotating external member and the rotating handle device are additionally arranged on the anti-loose nut, thus, the inested spring can be loosened or tightened more conveniently, and then the anti-loose nut can be used more conveniently.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a nut with good anti-loosening effect. 【Background technique】 [0002] Nuts are common fasteners. Traditional nuts generally do not have an anti-loosening function. Since many bolts and nuts are used on machines, after starting the machine, the machine will vibrate a little. Therefore, when the bolts and nuts have been used for a long time , the nut will loosen or even break away from the bolt, which will have an important impact on the normal operation of the machine. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art and to propose a nut with good anti-loosening effect. The present invention adds a built-in spring ferrule to the nut, thereby effectively preventing the bolt and the nut from being damaged by the machine for a long time. Vibration causes the nut to loosen, thereby increasing ...
