Abstract

The invention relates to a connecting device for a compression spring. The connecting device comprises a spring body, a first connecting sleeve and a second connecting sleeve, wherein the spring body is formed by curling overlaying of a metal strip; an annular bulge is arranged at the upper end of the first connecting sleeve, a threaded first groove matched with the spring body is formed in the outer surface of the bulge, and an opening is formed in a position, which is located at an opening end of the bulge, of the first groove; a threaded second groove matched with the spring body is formed in the inner wall of the second connecting sleeve, and an opening is formed in a position, which is located at an opening surface of the lower end of the second connecting sleeve, of the second groove; the lower end of the spring body is rotationally inserted in the first groove to be fixedly connected with the first connecting sleeve, and the upper end of the spring body is rotationally inserted in the second groove to be fixedly connected with the second connecting sleeve. According to the connecting device for the compression spring, the spring body is rotationally inserted in the first and second grooves to be fixedly connected with the connecting sleeves, so that the firmness of the spring and a connecting piece is greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a connection device for a compression spring. Background technique [0002] Ordinary springs and connecting parts are mostly directly socketed with the outer wall of the connecting part through the spring, and the spring is prevented from slipping through the friction between the inner wall of the spring and the outer wall of the connecting part. The outer wall of the part is worn, which eventually leads to the loosening of the spring or the scrapping of the connecting part. Contents of the invention [0003] The technical problem to be solved by the present invention is: to solve the above existing problems, provide a connection device for compression springs, which solves the problems of easy loosening and wear between ordinary springs and connection devices. [0004] The technical solution adopted by the present invention to solve the technical problem is: a connecting device for compressing springs, including a spring b...
