Zipper lower stopper and quick-release zipper using same

Abstract

The invention discloses a zipper lower stopper and a quick-release zipper using the same, the lower stopper is provided with a middle reference line corresponding to a zipper occlusion middle position, and the lower stopper comprises a left stop piece and a right stop piece; an inserting groove and a left splicing part are arranged in front of and behind the left stop piece; a bolt and a right splicing part are arranged in front of and behind the right stop piece; the inner side track of the bolt is a convex arc, the right stop piece can be movably and obliquely inserted into the inserting groove through the bolt and rotates leftwards to be spliced with the left stop piece, and in the splicing state, the arc of the bolt extends to the left side of the middle reference line; an inner concave area is formed on the inner side of the right splicing part, an outer convex area is formed on the inner side of the left splicing part, the inner concave area and the outer convex area are splicedin a matched mode, and in the splicing state, the track line corresponding to the outer convex area is larger to the right side of the middle reference line, and a guide inclined face is formed at therear end of the outer convex area. According to the quick-release zipper, the purposes of quick splicing, quick release and high buckling strength are achieved.

Description

technical field [0001] The invention relates to the technical field of zippers, in particular to a bottom stop of a zipper and a quick release zipper using the bottom stop. Background technique [0002] In the zipper design, a zipper top stop component and a zipper bottom stop component are usually arranged at two ends of the zipper. The bottom stop component of the zipper is installed at the end of the two chain belts at the starting point of the slider, and is used to fasten the bottom ends of the separated two chain belts together before the slider starts, so that the two chain belts can be closed by the action of the slider. At present, the traditional zipper bottom stop assembly includes a pin and a socket, and the slider and the socket are arranged on the same chain belt. When the zipper is assembled, the slider and the socket are arranged close to each other, and the pin is first inserted through the slider from top to bottom, and then inserted into the socket and in...

AI Technical Summary

Problems solved by technology

[0003] The pulling and disengaging operation of the existing zipper is not smooth enough in operation gestures, which affects the operation speed, especially in the disengaging action, which requires manual reverse (relative to the opening direction of the slider) operation, which cannot meet the requirements for fast pulling the zipper in practice. Engagement and Disengagement Functional Requirements

In addition, there is a certain conflict between the quick release function of the bottom stop and the fastening strength. In the current design of the bottom stop, on the basis of realizing quick release, there are usually insufficient buckling strengths, which affects the fastening of the bottom stop. Combine basic functions, and ultimately affect its actual applicability
