Novel anti-loose nut

Abstract

The invention provides a novel anti-loose nut. The novel anti-loose nut comprises a nut body, wherein a threaded hole is formed in the axis position of the nut body, internal threads are formed in the threaded hole, the two end faces, namely an upper end face and a lower end face, of the nut body are inwardly-concave four-sided arched surfaces, and three radial grooves are formed in the internal wall of the threaded hole. According to the novel anti-loose nut, when the two arched end faces are in contact with a to-be-connected part, the two arched end faces can deform and then generate an elastic deformation force, the nut provided by the invention is forced to be tightly pressed on the surface of the to-be-connected part, the frictional force between the novel nut and the to-be-connected part can be increased accordingly, and the anti-loose performance is relatively strong when the nut is subjected to strong vibration; in addition, due to the grooves in the internal wall of the threaded hole, impurities generated due to the rusting of the novel nut can be discharged through the grooves, so that the novel nut is easy and convenient to turn, and the service life of the novel nut is prolonged.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a novel anti-loosening nut which can prevent thread rust and effectively remove thread rust stains and impurities. Background technique [0002] Nuts are parts that are screwed together with bolts for fastening, and are an essential part of all manufacturing machinery. The upper and lower ends of traditional nuts are mostly smooth planes. The friction between this smooth plane and the surface of the connected parts is generally very small. When encountering strong vibration, the nut will loosen. , affecting the working reliability of the equipment; when in use, the thread of the nut is prone to rust and impurities, which cannot be ruled out to cause difficulty in disassembly and assembly and shorten the service life of the nut. Contents of the invention [0003] The problem to be solved by the present invention is to provide a new anti-loosening nut that is not easy to loose...
