Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0011] see figure 1 , the embodiment of the present invention includes:

[0012] A locknut, a bolt (or screw, stud, etc.) etc.), industrial parts, spacers, first nut 5 and second nut 6.

[0013] The shape of one end of the first nut 5 is designed as a continuous spiral curved surface 8 whose radial dimension gradually increases. The pitch of the continuous spiral curved surface 8 is the same as the pitch of the first nut, the second nut, and the bolt (or screw, stud, etc.).

[0014] After the threaded hole of the first nut, the threaded hole of the second nut and the bolt (or screw, stud, etc.) are screwed together and assembled, the protrusio...

Abstract

The invention discloses a locknut which comprises a first nut body and a second nut body, the appearance of one end of the first nut body is a continuous spiral curved surface with the radial size gradually increased, one end of the second nut body is a cylindrical body, and a protrusion is arranged on the inner side of the cylindrical body; and the protrusion is in gradually enhanced interference fit with the continuous spiral curved surface, with the gradually increased radial size, of the first nut body, therefore, continuously increasing acting force and friction force are generated between the contact surfaces of the first nut body and the second nut body as well as between the threads of the screwing parts of the first nut body, the second nut body and a bolt (a common bolt used for assembling or a screw, a stud and the like), mutual locking is achieved, and reliable looseness prevention is achieved.

Description

technical field [0001] The invention relates to the field of anti-loosening threads, in particular to an anti-loosening nut. Background technique [0002] At present, in product assembly, threaded fasteners and threaded parts are generally used for assembly. The anti-loosening measures are usually implemented with spring washers, insert nuts, double nuts, etc. However, when this anti-loosening measure is used in a scene with many unfavorable factors such as vibration, impact, and alternating load, it is easy to loosen. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a locknut, which can reliably prevent loosening when used in the above unfavorable scenarios. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a lock nut, including: a first nut and a second nut, and the shape of one end of the first nut is designed as a conti...
