Description

Can dismantle end zipper lower stop structure and this end zipper of closing of pull head

Technical Field

The utility model belongs to the technical field of zipper manufacturing, and particularly relates to a closed-end zipper lower stop structure with a detachable slider and a closed-end zipper.

Background

As one of the ten inventions in the twentieth century, the zipper has been widely applied to human daily life and various industries, from aerospace and aviation, to deep sea, from national defense and military, to daily civilian use, from industry to agriculture and fishery, and from medical sanitation to environmental protection. The zipper technology relates to almost all technical fields of hardware industry, also includes specialties such as weaving, coating, punching press, injection molding, casting, cold drawing, electroplating, printing and dyeing, and has typical characteristics of modern industrialized mass production: the method is accurate, strict and efficient, and advanced enterprises in the industry are developing to full automation in recent years.

However, the sliders of the resin closed-end zippers on the market cannot be detached under the common condition. If a customer wants to replace the pull head after the order production is finished, or the pull head is mistakenly assembled in the order production process, the top stop is firstly detached, and the top stop is injected again after the pull head is replaced. The disadvantages of this are: (1) the production time is long, and the cost is high; (2) the customer can not replace the injection molding machine by himself (replacement requires a special injection molding machine); (3) the process of disassembling the upper stop is easy to damage the band rib to cause insufficient follow-up strength.

Therefore, it is necessary to design a bottom stop structure of a closed-end zipper for easy detachment and replacement of the slider.
