Abstract

The invention discloses a thread locking structure, which is used for locking a screw for connecting an upper connecting piece and a lower connecting piece together, and comprises a through hole formed in the upper connecting piece and a threaded hole formed in the lower connecting piece, a locking gasket is arranged between the through hole and a screw cap of the screw, a clamping groove is formed in the screw cap, and the threaded hole is arranged in the clamping groove. The locking gasket is provided with a bending part which can be clamped into the clamping groove; the locking gasket is provided with a positioning protrusion, the through hole is provided with a positioning groove for the positioning protrusion to be clamped in, or the locking gasket is provided with a positioning groove, and the through hole is provided with a positioning protrusion clamped in the positioning groove. The positioning protrusion is clamped into the positioning groove to achieve angular position fixation between the locking gasket and the upper connecting piece, and after the threads are tightened, the bent portion is clamped into the clamping groove, so that angular position fixation among the screw, the locking gasket and the upper connecting piece is achieved.

Description

[0001] This application is a divisional application of an invention patent application with publication number CN108317152A. The filing date of the original application is: 2018.04.09; the application number is: 201810305483.4; the name of the invention is: "A Thread Stopping Structure". technical field [0002] The invention relates to a thread stop structure. Background technique [0003] Threaded connection is the most widely used connection method in fasteners. According to the anti-loosening mechanism, it can be roughly divided into four categories: frictional anti-loosening, mechanical anti-loosening, riveting anti-loosening and structural anti-loosening. Among them, mechanical anti-loosening is recognized as the most reliable anti-loosening method for use environments such as shock, vibration, and variable load. The core of thread mechanical anti-loosening is its stop structure. At present, the commonly used stop structures include cotter pins, series steel wires and ...
