A kind of slip buckle type anti-loosening nut

Abstract

The invention discloses a slide buckle type locknut mainly applied to the mechanical field; the slide buckle type locknut has an interlocking function, and is easy to manufacture and use, and the locknut can be further reused; the locknut is composed of a nut A and a nut B; according to the working principle of the locknut, the nut B is firstly tightened on a bolt so that a workpiece is pressed bythe lower end of the nut B, and then the nut A is tightened on the bolt with the extrusion portions facing downwards; the upper ends of a plurality of columns of the nut A are slide along the lower ends of the threaded segments of a plurality of slide buckle convex ribs of the nut B, the upper ends of the columns and the lower ends of the threaded segments of the slide buckle convex ribs are extruded mutually and deformed elastically; after the multiple columns of the nut A enter the half-arc segments of the corresponding multiple slide buckle convex ribs of the nut B, the multiple columns ofthe nut A are restored elastically; interlocking between the nut A and the nut B is achieved; meanwhile, a plurality of arc segments of the nut B are extruded by the extrusion portions of the nut A,and external threads of the bolt are extruded by internal threads B of the multiple arc segments, so that the external threads of the bolt are tightly clamped, and the purpose of anti-looseness is achieved.

Description

technical field [0001] The invention is mainly used for fixing components in the field of machinery or construction, and is especially suitable for fixing components that often vibrate. Background technique [0002] The currently used or patented anti-loosening nuts cannot be interlocked, and eventually the nut will be loosened from the bolt; although some nuts have an anti-loosening locking function, additional accessories need to be added, which is inconvenient to manufacture and use. Contents of the invention [0003] The present invention solves the above-mentioned problems. It has an interlocking function, and the nut after tightening will not loosen from the bolt, and does not need to add additional accessories. It is convenient to manufacture and use, and the lock nut can be reused; it consists of nut A1, Composed of B6; the nut A1 is composed of a screw body A2, an extrusion part 3, and a plurality of cylinders 4. The screw body A2 has an internal thread A5, and th...
