Self-locking fastener with adjustable locking position

Abstract

The invention relates to the technical field of hardware fasteners, in particular to a self-locking fastener with the adjustable locking position, which comprises an external thread assembly rod and an external assembly nut. The self-locking fastener with the adjustable locking position is composed of the external thread assembly rod and the external assembly nut, and a strip-shaped mounting groove internally provided with an external thread assembly plate is formed in the outer side face of the external thread assembly rod. The assembling position of the external thread assembly nut is limited through mutual meshing of the external thread assembly plate and the strip-shaped mounting groove, and the mounting and self-locking modes can be more diversified by changing the assembling angle of the external thread assembly plate. An elastic arc-shaped lateral extrusion plate is arranged on the external assembly nut, a lateral locking groove with a slope on one side and an elastic overturning limiting plate on the other side is formed in the outer side of the external thread assembly plate, position locking and fixing are completed by inserting the elastic arc-shaped lateral extrusion plate into the lateral locking groove, the leading-in resistance is reduced, and the firmness and the safety of inserting and limiting can be improved.

Description

technical field [0001] The invention relates to the technical field of hardware fasteners, in particular to a self-locking fastener with an adjustable locking position. Background technique [0002] The fastener is mainly composed of a screw and a nut, wherein the screw is a cylinder with a spiral groove cut on the outer surface or a cone cut with a conical surface with a spiral groove. The screw has a different head, like the head in the picture is called an external hexagonal screw. There are others, such as large flat screws, hexagon socket screws and so on. Nuts, also known as nuts, are parts that are screwed together with bolts or screws for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as Copper) and other major types. [0003] Screws and nuts are very common fastening hardware on the market. The traditional screw and nut structure is simple and fixed, and the struc...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved self-locking fastener with adjustable locking position is provided, which solves the problem that the traditional screw and nut structure is simply fixed and cannot be adjusted and assembled according to actual needs. The structure of the end leads to the limitation of the installation method, the connection surface between the screw and the nut cannot be fixed by self-locking, and the assembly safety is very limited.
