Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention has a groove on the outer surface of the hex nut, specifically, three of the six outer sides of the hex nut 1 are provided with a groove 2, and the inner thread of the hex nut protrudes and deforms inwardly, and the deformed thread During the assembly process, the anti-loosening torque is generated to achieve the loosening effect.

[0018] The shape of the specifically implemented groove is rectangular, the groove is located in the middle of the outer surface of the hex nut, and the groove depth is several millimeters.

[0019] After the ordinary hexagonal nut 1 is processed, a groove 2 is stamped on three of the six outer sides of the hexagonal nut 1 which are uniformly distributed. During stamping, the inner ring thread of the hexagonal nut produces inward convex deformation, and the internal thread prod...

Abstract

The invention discloses a novel anti-loose self-locking hexagonal nut and a processing treatment method. Each of three uniformly-distributed surfaces of the six surfaces of the outer side of the hexagonal nut is provided with a groove, and inner ring threads of the hexagonal nut protrude inwards to deform; and anti-loose torque is generated by the deformed threads in the assembling process, so that the anti-loose effect is achieved. According to the novel anti-loose self-locking hexagonal nut and the processing treatment method, the complex problem that a nut washer and a gasket are required to be added to a conventional hexagon nut at present and the problem that looseness is easily caused can be solved, the cost is reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to a hexagon nut, in particular to a novel anti-loosening self-locking hexagon nut and a processing method. Background technique [0002] Traditional hex nuts require additional nut washers and are prone to loosening. Now ordinary hex nuts need to cooperate with washers to increase the anti-loosening torque, and in special cases, once loosened, there is no anti-loosening effect. Contents of the invention [0003] In order to solve the problems in the background technology, the present invention provides an anti-loosening self-locking hex nut and a processing method. [0004] The technical scheme adopted in the present invention is: [0005] Among the six outer sides of the hexagonal nut of the present invention, three evenly distributed surfaces are provided with a groove, and the inner thread of the hexagonal nut protrudes and deforms inwardly. [0006] The hex nuts are made of metal. [0007] The shape of the groove is rec...
