Problems solved by technology

Fasteners are widely used in China. Many fasteners are in heavy-duty and vibrating working environments, and they are prone to loosening. Once the fasteners in some parts become loose, it is likely to cause serious accidents or even endanger life.
In the prior art, the nylon sleeve locking anti-loosening nut uses the nylon sleeve inlaid on the upper end of the nut to play a self-locking and anti-loosening effect. The nut cannot guarantee the reliability of anti-loosening after multiple disassembly and assembly, and needs to be replaced nuts, thereby increasing the cost of use

Abstract

The invention discloses a flange nut with a retaining function. The flange nut with the retaining function comprises a nut body, an annular seat, a retaining mechanism and a flange pad, wherein the flange pad is arranged at the front end of the nut body, the annular seat is arranged at the rear end of the nut body, the detachable retaining mechanism is arranged in the annular seat, and the retaining mechanism comprises a nylon sleeve, a plurality of inserting bodies, a fixing seat, a stepped hole and a plurality of inserting grooves, wherein the fixing seat is detachably arranged in the annular seat, the stepped hole is formed in the fixing seat, the plurality of inserting grooves which are uniformly distributed are formed in the side wall of a large-aperture section of the step hole, and the nylon sleeve is located in the large-aperture section of the step hole. Compared with the prior art, the use cost can be reduced, the replacement is convenient, and the damage to the surface of a workpiece is not easily caused.

Description

【Technical field】 [0001] The invention relates to the technical field of a flange nut, in particular to the technical field of a flange nut with a backstop function. 【Background technique】 [0002] The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic load. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Fasteners are widely used in China. Many fasteners are in heavy-duty and vibrating working environments, and they are prone to loosening. Once the fasteners in some parts become loose, it is likely to cause serious accidents or even endanger life. In the prior art, the nylon sleeve locking anti-loosening nut uses the nylon sleeve inlaid on the upper end of the nut to play a self-locking and anti-loosening effect. The nut cannot guarantee the reliability of anti-loosening after multiple ...
