Puller, zipper and puller processing method

Abstract

The invention discloses a puller, a zipper and a puller processing method, and the puller comprises: a core part which is made of a metal material, wherein an inner cavity for teeth of a zipper to pass through is formed in the core part, the side wall of the core part is provided with a blocking edge for preventing the teeth from being disengaged and a gap which is communicated with the inner cavity and used for cloth belts of the zipper to pass through, the front end of the core part is provided with front end openings for the two cloth belts of the zipper to pass through respectively, the tail end of the core part is provided with a tail end opening through which two cloth belts of the zipper can pass in a combined manner; and a shell, wherein the shell is made of a ceramic material, theshell covers the outer side of the core part, areceding gap for receding the gap is formed in the side wall of the shell, the front end of the shell is provided with a front end receding opening forreceding the front end opening, and the rear end of the shell is provided with a rear end receding opening for receding the rear end opening. According to the puller, normal opening and closing of thezipper are guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of slide fasteners, in particular to a slider, a slide fastener and a slider processing method. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate. It is widely used in clothing, bags, tents and other equipment. Different use environments will cause irreversible damage to the quality of the zipper. The slider on the zipper mainly includes two types, one is a slider made of pure metal, and the other is a slider made of pure ceramic. [0003] Among them, for sliders made of pure metal, the surface of the slider needs to be protected by a layer of surface treatment (painting, electroplating, vacuum plating, etc.), and the process increases. In addition, the surface coating is easy to be damaged by violent use or in harsh environments. Damage, such as outdoor environment, long-term sun and rain, the slider is easy to r...

AI Technical Summary

Problems solved by technology

[0003] Among them, for sliders made of pure metal, the surface of the slider needs to be protected by a layer of surface treatment (painting, electroplating, vacuum plating, etc.), and the process increases. In addition, the surface coating is easy to be damaged by violent use or in harsh environments. Damage, such as outdoor environment, long-term sun and rain, the slider is easy to rust after the surface treatment is damaged and cannot be used normally, which affects the service life

[0004] The slider made of pure ceramic material is made by sintering at high temperature once, and the finished product needs to be polished, so the fine structure inside the slider cannot be realized, and the size error is large, so the normal opening and closing of the zipper cannot be guaranteed.
