Anti-bursting chain tooth and zipper with anti-bursting chain tooth

Abstract

The invention discloses an anti-bursting chain tooth and a zipper with the anti-bursting chain tooth. The anti-bursting chain tooth comprises a third woven belt clamping body and a fourth woven belt clamping body adjacent to the third woven belt clamping body. A third pulling-close plate is arranged on the top of the third woven belt clamping body, a third convex part and a third groove are arranged on the side face of one side of the third pulling-close plate, and a third convex part and a third groove with the interchangeable positions are arranged on the side face of the other side of the third pulling-close plate. A fourth pulling-close plate is arranged on the top of the fourth woven belt clamping body, a fourth groove corresponding to the third convex part and a fourth convex part corresponding to the third groove are arranged on the side face, close to the third pulling-close plate, of the fourth pulling-close plate, and a fourth groove and a fourth convex part with the interchangeable positions are arranged on the side face, away from the third pulling-close plate, of the fourth pulling-close plate. The two side faces of the anti-bursting chain tooth are both provided withtwo engagement points, one anti-bursting chain tooth can be supported by four contact points, no jamming phenomenon exists, and it is guaranteed that the zipper with the anti-bursting chain tooth doesnot burst in the bending process.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an explosion-proof fastener element and a zipper using the explosion-proof fastener element. Background technique [0002] There are two main types of fastener elements for zippers today: [0003] One type of chain teeth is corn teeth, such as figure 1 , figure 2 and image 3 As shown, the corn tooth includes a first cloth tape clamping body 1, the top of the first cloth tape clamping body 1 is provided with a first tension plate 2, and both sides of the first tension plate 2 are provided with first protrusions 3 , the first pull plate 2 between the first protrusion 3 and the first cloth tape holder 1 is provided with a protective plate 4 corresponding to the first protrusion 3, when the zipper using corn teeth is pulled and closed , the first protrusions 3 on the two contacting corn teeth are pressed against each other, and the first protrusions 3 on the contactin...

Problems solved by technology

[0003] One type of chain tooth is a corn tooth, such as figure 1 , figure 2 and image 3 As shown, the corn tooth includes a first cloth tape clamping body 1, the top of the first cloth tape clamping body 1 is provided with a first closing plate 2, and both sides of the first closing plate 2 are provided with first protrusions 3 , the first pull-up plate 2 between the first protrusion 3 and the first tape clamping body 1 is provided with a guard plate 4 corresponding to the first protrusion 3, when the zipper using corn teeth is pulled , the first protrusions 3 on the two contacting corn teeth squeeze each other, and fix the first protrusions 3 on the contacting corn teeth between the guard plate 4 and the first tape holder 1 For a while, this kind of zipper using corn teeth has the following problems: one is that the slider feels heavy when it is pulled, and it will jam in severe cases; the other is that the zipper using corn teeth will burst when it is bent. Today's The solution is a metal double-sided chain tooth disclosed in the Chinese invention patent with application number ZL200810130182.7, which solves the problem that the slider feels heavy when pulling, but does not solve the problem that the zipper using corn teeth will occur when it is bent. Burst phenomenon, due to the large size of the convex part and the groove part of the metal double-sided chain teeth, while increasing the meshing force, it is also easy to bite the adjacent fabric such as the inner lining into the zipper, which will cause the zipper to be damaged in severe cases. damage

[0004] Another chain tooth is European tooth, such as Figure 4 , Figure 5 and Image 6 As shown, Ouya includes a second cloth tape holder 5, a second pull-up plate 6 is provided on the top of the second cloth tape holder 5, and a second protrusion 7 is provided on one side of the second draw-close board 6 , the other side of the second pull-up plate 6 is provided with a first groove 8 corresponding to the second protrusion 7, when the zipper using the Ou tooth is pulled, a second protrusion 7 of the Ou tooth is inserted In the first groove 8 on the adjacent Ouya, so as to achieve the effect of tightening and closing. The problems of the current Ouya are: first, the slider feels heavy when the zipper is opened, and it will be stuck when it is serious. , the second is that the Ouya zipper will burst when it is bent. The current solution is to add chamfers to the top of the Ouya. Although it can reduce the difficulty of opening the zipper, it cannot completely solve the problem when the zipper is opened. The problem of feeling the head is heavy

[0006] One is that the slider feels heavy when you pull it, and it will get stuck when it is serious. The other is that the zipper using corn teeth will burst when it is bent. The third is that it is easy to bite into the zipper such as the inner lining and other adjacent fabrics.
