Abstract

The invention discloses a nut combination with an anti-loosening function, and relates to the technical field of fastening devices. The nut combination comprises a disc-shaped nut body and a disc-shaped gasket; an internal thread is arranged in the middle of the disc-shaped nut body; the dish-shaped gasket is provided with a through hole matched with the internal thread on the disc-shaped nut body; the disc-shaped nut body and the disc-shaped gasket are integrally inclined, and the inclination angle is 2-15 degrees; the disc-shaped nut body and the disc-shaped gasket are adjacently arranged and are locked on the bolt; and the disc-shaped gasket is arranged on the inner side of the disc-shaped nut body. The nut combination 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 nut combination 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 nut combination with anti-loo...
