Abstract
Semicircle tooth zipper is unique,And engage locking fastening,Larger mastication forces also are difficult to tear slide fastener on two dimension directions,But when the slide fastener to prior art is bent,It is in explosion like that can disengage intermeshing chain tooth,Because when slide fastener bending,Intermeshing zipper tooth both ends stress presses together on two chain bands,But also leave gap between two zipper tooth upper tooth shoulders adjacent on same chain band,The gap causes slide fastener when being squeezed,Intermesh structural instability,Simultaneously,The structure of engaging piece makes zipper tooth not fastened in engagement,The phenomenon that zipper tooth pops occurs,It is a primary object of the present invention to provide a kind of semicircle zipper tooth by changing the structure of engaging piece,Make chain tooth in the presence of by various external force,Particularly in the presence of "U" shaped extruding force,It is intermeshing between chain tooth more to fasten,It is not easy to disengage.
Description
Technical field
The present invention relates to zipper technology field, more particularly to a kind of semicircle zipper tooth.
Background technology
The design of semicircle tooth zipper is unique, when zipper tooth is intermeshed, intermeshing zipper tooth semicircular in shape, and
And locked when being intermeshed for dual engagement, the first grinding tooth recess of zipper tooth and the second grinding tooth recess phase of another zipper tooth
Mutually engagement, the first location division and the second location division of zipper tooth are mutually blocked and locked with the locating slot of another chain tooth, and it is at two
Locking is engaged on dimension direction to chain tooth, the chain tooth of interaction is engagingly more fastened, even in from right and left
Upward larger external force is torn, and intermeshing zipper tooth is also not easy to disengage.
In the prior art, such as the product that CN106165946A designs for the applicant, although semicircle tooth zipper is only
Spy, and locking fastening is engaged, larger mastication forces also are difficult to tear slide fastener on two dimension directions, but applicant is right
During it is tested, it is found that the technology has a defect, when the slide fastener to prior art is bent, such as by slide fastener
When being converted into "U" shaped, continue to apply its U-shaped bottom the power of extruding, it is in explosion like that can disengage intermeshing chain tooth, Shen
Ask someone to study it discovery, because when slide fastener is converted into "U" shaped, nibbled mutually on two chain bands of "U" shaped bottom inside
The zipper tooth both ends stress of conjunction presses together, but adjacent on the same chain band of "U" shaped bottom inside two
Gap is also left between zipper tooth upper tooth shoulder, the gap causes slide fastener when by the extruding force of U-shaped, and chain tooth is intermeshed knot
Structure is unstable, meanwhile, the structure of engaging piece makes zipper tooth not fastened in engagement, and the phenomenon of slide fastener " quick-fried tooth " just occurs.
The content of the invention
The present invention makes in view of the above problems, and the main purpose invented described in technical scheme 1 is to provide a kind of half

Stretch.
Preferably, the width on the engagement convex surface is two sides for connecting first engagement recess and the second engagement recess
The distance between edge, the distance taper into or constant along the direction away from engagement card face.
Preferably, the width on the engagement convex surface be less than adjacent two zipper tooth upper tooth shoulders on same chain band away from
From.
Preferably, the both sides of the edge on the engagement convex surface are in chain belt bending to U-typed, the engagement of U-typed bottom inside
Convex surface both sides of the edge respectively the zipper tooth adjacent with relative chain band the edge for engaging convex surface against.
Preferably, the engagement card face is when chain belt is bent into U-typed, and two on the engagement card face of U-typed bottom inside
On individual tooth shoulder and same chain band the tooth shoulder of adjacent zipper tooth against.
Preferably, first engagement recess be arc recess, and the concave surface of the recess from the first location division to
Upper and lower ends are gradually deepened；
