Abstract

The invention discloses a self-locking zipper head, which comprises a slide block body, an elastic element and a self-locking element. A zipper pull stopper and a through hole are formed on an upper wing plate of the slide block body; one end of the zipper pull stopper is connected with the upper wing plate of the slide block body; a gap is formed between the other end of the zipper pull stopper and the upper wing plate of the slide block body to make a pull rod of the zipper pull pass through; the self-locking element is rotationally pivoted on the slide block body and comprises a fastening part, a hooking part and a pressing part, wherein the pressing part is arranged on the front end of the self-locking element; the fastening part is arranged on the rear end of the self-locking element; the hooking part is obliquely arranged downwards from the bottom end of the pressing part; the elastic element is connected with the slide block body and the pressing part of the self-locking element respectively; and during operation, by rotating the self-locking element, a gap is formed between the fastening part of the self-locking element and the upper wing plate of the slide block body so as to make the pull rod of the zipper pull pass through. The self-locking zipper head has the advantages of simple structure and convenience of automatic assembly.

Description

technical field [0001] The invention relates to a zipper puller, in particular to a self-locking zipper puller with detachable and replaceable sliders.
