Description

The firm slide fastener of occlusion

Technical field

The utility model is related to slide fastener field, and in particular to a kind of firm slide fastener of occlusion.

Background technology

Existing slide fastener mainly includes strap and the chain tooth being arranged on cloth band.In order to describe conveniently, when slide fastener sewing exists On the objects such as case and bag, clothes, slide fastener drawing subsequently point to case and bag, outside clothes for outside, it is interior to point to case and bag, clothes inner face Side.

Wherein, chain tooth includes the tooth head, neck and the tooth tail that are connected in turn, if from the point of view of inward-outward direction, Chain tooth includes the relative outer tooth being bonded together and interior tooth again.

During slide fastener drawing, two row chain tooth relative misalignments are interlocked.When outward bending after slide fastener drawing, mutually stagger Mutually supported between the outer tooth of occlusion, the perturbed force disengaged is produced to the outer tooth being interlocked, it is easy to disengaged chain tooth and sting Close, it is poor that it is engaged steadiness.Similarly, bend inwards the slide fastener of drawing, is mutually supported between interior tooth, to what is be interlocked Interior tooth produces the perturbed force disengaged, is also easy to close chain gutta-percha open bite, it is also poor that it is engaged steadiness.

Utility model content

The purpose of this utility model is the chain tooth for providing a kind of firm slide fastener of occlusion, and it is difficult to take off under bending state Open bite is closed.

The utility model is achieved through the following technical solutions：The firm slide fastener of occlusion, including：A pair of zipper strips；A pair of cores Portion, they are set respectively along the relative band side edge part of a pair of zipper strips；A pair of slide fastener coupling element row, they are respectively arranged on a pair Core, with plastic multiple slide fastener coupling elements；One pull head, it makes the engagement of pair of right and left slide fastener coupling element row or separated, and it is special Levy and be, there is each chain tooth a hook part and one to hook groove, along a neck is provided with the outside of hook part, be provided with and a neck on the inside of groove along hooking The card division of occlusion, the slide fastener coupling element of the right and left is engaged in opposite direction.

Further, each chain tooth described in the utility model is provided with stopper section along edge.

Further, the both sides of stopper section described in the utility model are convex portion, and centre is recess.

Further, the cross section of stopper section described in the utility model is wave-like.

The utility model compared with prior art, with advantages below and beneficial effect：The utility model chain tooth uses phase The hook part of opposite direction is engaged with hooking groove, is made the pair of right and left slide fastener coupling element backward both sides of row engagement difficult for drop-off to drawing, is passed through simultaneously The snapping of neck and card division in chain tooth, makes drawing is not easy to come off before and after the row engagement of pair of right and left slide fastener coupling element is backward, protects Slide fastener multiple directions are difficult for drop-off to drawing, so as to improve the joggled strength of slide fastener coupling element.
