Self-locking zipper puller

Abstract

The invention discloses a self-locking zipper puller. The zipper puller comprises a slider body, a cap, a shrapnel, a hook and a pulling piece; the cap is buckled on the slider body; the shrapnel is arranged at the top part of the cap through a limiting device; the upper surface of an upper flange of the slider body is provided with a locating device and a cap buckling base of the hook; one end of the hook is located on the locating device; the hook, the shrapnel and the cap penetrate through a rectangular opening of the pulling piece; the lower surface of the shrapnel leans against the upper edge of the hook; the shape of the shrapnel is that the middle part is a flat plate and the two ends are tilted upwards in an obtuse angle. According to the self-locking zipper puller provided by the invention, the production process of the shrapnel and the cap is simple, the elasticity of the shrapnel is moderate, and the contact effect is good, so that the false lock and the insecure lock can be effectively avoided, and the technical effects of light in lifting the crotch and sensitive in making the crotch can be realized. The self-locking zipper puller is made of the conventional raw materials of the industry, and has the advantages of low cost and reliable locking.

Description

technical field [0001] The invention relates to a zipper puller, in particular to a self-locking zipper puller. Background technique [0002] The existing zipper slider includes a slider body, a cap, a shrapnel, a hook and a pull piece. The shrapnel is limited in the cap; A cap seat is provided, and the two ends of the cap are engaged with the cap seat respectively. The shrapnel presses against the horse hook so that the hook point at the tail of the horse hook penetrates downward from the opening on the upper wing plate into the gap of the zipper teeth, so as to realize self-locking, so that the slider body will not slide freely. There is an opening on the pull tab, through which the shrapnel and the hook pass, and the hook can be lifted up by pulling the tab, and the self-locking can be released, and the zipper can be opened and closed freely. The existing shrapnel is generally in the shape of a "one" flat plate, or a "V" plate with upturned ends. The "one" flat plate sh...

AI Technical Summary

Problems solved by technology

The existing shrapnel is generally in the shape of a "one" flat plate, or a "V" plate with upturned ends. The "one" flat plate shape generally requires a special limit block with a raised edge in the cap. Manufacturing difficulty and high cost, but the "V" plate-shaped shrapnel has a small contact surface with the horse hook, and the use stability is poor
