Structure-adjustable self-locking screw rod

Abstract

The invention relates to the technical field of hardware assembly parts, in particular to a structure-adjustable self-locking screw rod. The structure-adjustable self-locking screw rod comprises a first external threaded rod and a second external threaded rod. According to the structure-adjustable self-locking screw rod, the first external threaded rod and the second external threaded rod are movably connected through an internal assembling shaft in a circular assembling through hole, and contraction grooves internally provided with elastic locking rings are formed in the assembling planes of the external threaded rods; the assembling angle between the first external threaded rod and the second external threaded rod is adjusted and fixed through mutual meshing of the elastic locking rings, so that the structure of the screw rod is adjustable, and the application range is wider; and lateral mounting inserting grooves internally provided with internal limiting inserting blocks are formed in the outer side faces of the external threaded rods, extrusion springs are limited by inserting internal limiting inserting blocks into lateral mounting inserting grooves, meanwhile, later assembling, disassembling and maintenance are facilitated, and the later use cost is reduced.

Description

Technical field [0001] The present invention relates to the technical field of hardware fittings, in particular a structurally adjustable self-locking screw. Background technique [0002] The screw is a cylinder having a spiral groove in the outer surface or a cone with a tapered spiral groove. The screw has a different head, a head hex screw like a picture. There are other, such as large flat screws, inner hex screws, etc. [0003] The nut is also known as the nut, which is a part that is screwed together with the bolt or screw together. One element that the manufacturing machinery must be used is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) according to the material. ) Wait a few types. [0004] The screw and nuts are very common fastening hardware parts on the market. The traditional screw structure is fixed, and it is unable to adjust the angle of the installation according to the actual needs. At the same time, the installation method is fix...

AI Technical Summary

Problems solved by technology

[0005] 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 structure-adjustable self-locking screw is provided, which solves the problem that the traditional screw structure is fixed and cannot be adjusted according to actual needs. The fixing method is limited, and the connection surface between the screw and the nut cannot be fixed by self-locking, which leads to the problem of very limited assembly safety.
