Problems solved by technology

[0002] Bolted connections are often used in mechanical design. Bolt looseness is a common factor affecting the reliability and safety of mechanical equipment. In order to prevent loosening, double-stacked self-locking washers are installed between the nut and the contact surface. However, the double-stacked self-locking washer includes two washers, and the front and back of the washers are different. If they are installed upside down, they will not be able to prevent loosening, and the two washers need to be bonded by glue, and the installation process is cumbersome.

Abstract

The invention relates to the technical field of nuts, in particular to a locking nut with an anti-loosening structure. The locking nut comprises a nut and a gasket matched with the nut, the nut comprises a nut body and a flange surface arranged on the end surface of one side of the nut body, and the end surface of the side, facing the gasket, of the flange surface is a first meshing surface; and the gasket is provided with a second meshing surface meshed with the first meshing surface, and the gasket and the nut are connected through a connecting structure. The locking nut with the anti-loosening structure has the beneficial effect that the self-locking anti-loosening effect of the locking nut is improved.

Description

technical field [0001] The invention relates to the technical field of nuts, in particular to a lock nut with an anti-loosening structure. Background technique [0002] Bolted connections are often used in mechanical design. Bolt looseness is a common factor affecting the reliability and safety of mechanical equipment. In order to prevent loosening, double-stacked self-locking washers are installed between the nut and the contact surface. However, the double-stacked self-locking washer includes two washers, and the washers have different front and back sides. If they are installed upside down, they will not be able to prevent loosening, and the two washers need to be bonded by glue, and the installation process is cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lock nut with an anti-loosening structure to improve the self-locking and anti-loosening effect of the lock nut in view of the above-mention...
