A zipper bottom stop and a quick-release zipper using the bottom stop

Abstract

The invention discloses a zipper bottom stop and a quick-release zipper using the bottom stop. The bottom stop has a median reference line corresponding to the middle position of the zipper bite. The bottom stop includes a left stop and a right stop; The groove and the left splitting part, the right stopper are provided with a pin and the right splitting part at the front and back; the inner track of the latch is a convex arc, and the right stopper can be inserted into the slot obliquely through the latch and rotated to the left to match the left stopper Stitching, in the splicing state, the arc of the bolt goes to the left of the median reference line; the inner side of the right splitting part forms an inner concave area, and the inner side of the left splitting part forms an outer convex area, and the inner concave area and the outer convex area Matching and splicing, in the splicing state, the trajectory line corresponding to the convex area goes to the right side of the median reference line, and a guiding slope is formed at the rear end of the convex area. The quick-release zipper in this case achieves the purpose of taking into account both quick snap-off and fastening strength.

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...

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
