Abstract

The invention discloses a threaded connection device with an anti-loosening function, and relates to the technical field of fastening devices. The threaded connection device comprises an anti-loosening nut comprises an anti-loosening nut body and a plurality of conical parts; an internal thread is arranged in the middle of the anti-loosening nut body; at least one telescopic groove is formed in the inner side of the anti-loosening nut body in the radial direction of the threads; and the multiple conical parts sleeve the outer side of the anti-loosening nut body and are in interference fit with the anti-loosening nut body. The threaded connection device with the anti-loosening function can be effectively prevented from loosening under the action of impact, vibration and variable load, and the safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of fastening devices, in particular to a threaded connection device with an anti-loosening function. Background technique [0002] In the prior art, bolts, washers, and nuts are usually used to fasten the connected objects, which will not loosen automatically under static load conditions. However, due to the working conditions of the connection, there will inevitably be shocks, vibrations, and variable loads. Under these working conditions, the friction force between thread pairs will disappear or decrease instantaneously; at the same time, in the case of high temperature or large temperature change, the material will undergo creep and stress relaxation, which will also reduce the friction force. Under multiple actions, it will cause the connection to gradually loosen, resulting in a safety accident. Contents of the invention [0003] The object of the present invention is to provide a threaded connectio...
