Abstract

The utility model discloses a double-open slide fastener which is characterized in that a transverse hook piece is arranged at a left plug-in or a right plug-in. Because the utility model adopts that a convex point which is arranged at the left plug-in or the right plug-in is canceled, thereby when producing the double-open slide fastener, the producer is capable of using a same common puller, reducing the type of the puller, therefore, the utility model is capable of increasing the production efficiency.

Description

Two open end zippers

Technical field:

The utility model relates to the technical field of slide fastener in the daily living article, specifically a kind of improved pair of open end zipper.

Background technology:

Slide fastener of the prior art is because the occasion difference of using, therefore polytype is arranged, as the slide fastener that is used in pocket often is sealing (remaining silent) slide fastener, and can separate as the limit, the slide fastener left and right sides of the jacket front part of a Chinese robe or jacket, so generally be to adopt to open tail (opening) slide fastener, down jackets of wearing during as for winter or snow clothing generally all are to adopt upper and lower all discerptible separating zipper.This slide fastener all can be opened because of upper and lower, so be called slide fastener or two open end zipper up and down, on left plug-in unit, be provided with salient point in the prior art, when pull head is moved lowermost end to instantly, blocked by the salient point on the left plug-in unit, in order to cooperate this salient point, the inwall of following pull head need be made the inwall of depression, be common pull head and go up pull head, therefore the inwall of promptly going up pull head need not made the inwall of depression, and its inwall is plane, must adopt two kinds of different pull heads when producing two open end zipper, otherwise can't produce, and two kinds of different pull heads tend to influence production efficiency.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved pair of open end zipper, and it can adopt two kinds of identical slider when producing two open end zipper.

To achieve these goals, the technical solution of the utility model is: two open end zippers, it mainly comprises the cloth belt, the sprocket of fixedlying connected with the cloth belt, upper and lower pull head with the flexible connection of cloth belt, with last pull head or the following left and right plug-in unit that is connected of pull head, it is characterized in that: be provided with at left plug-in unit or right plug-in unit and laterally collude piece.

The utility model is owing to cancelled salient point on left plug-in unit or right plug-in unit, when producing two open end zipper, can make upper and lower pull head adopt a kind of identical common pull head, reduced the kind of pull head, and then improved production efficiency, when pull head is moved lowermost end to instantly, the piece that laterally colludes that following pull head can be set at left plug-in unit or right plug-in unit blocks, and can not deviate from slide fastener, this laterally colludes piece in addition also the function that pull head is located, so that can merge with left plug-in unit when right plug-in unit inserts, supplying down, pull head upwards draws the effect of closing tooth that reaches smoothly.

Fig. 1 is the schematic diagram of prior art

Fig. 2 is the structural representation of the utility model one embodiment

Fig. 3 is a schematic diagram of removing pull head among Fig. 2

Fig. 4 is the structural representation of another embodiment of the utility model

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises cloth belt 5, the sprocket 6 of fixedlying connected with cloth belt 5, in the flexible connection of cloth belt, following pull head 1, a left side that is connected with last pull head or following pull head, right plug-in unit 2, it is different from prior art and is: be provided with at left plug-in unit or right plug-in unit and laterally collude piece 3, this laterally colludes the end that piece 3 is arranged on close left plug-in unit or right plug-in unit, on, it is plane that the inwall of following pull head all is, laterally collude the single face that piece both can be arranged on left plug-in unit or right plug-in unit in the enforcement, can be arranged on the two-sided of left plug-in unit or right plug-in unit again, the material of slide fastener mostly adopts nylon, plastic-steel or metal manufacturing, the mark 4 expressions salient point of the prior art in the accompanying drawing.

Claims

1, two open end zippers, it mainly comprises the cloth belt, and the sprocket of fixedlying connected with the cloth belt is with the upper and lower pull head of cloth belt flexible connection, with last pull head or the following left and right plug-in unit that is connected of pull head, it is characterized in that: be provided with at left plug-in unit or right plug-in unit and laterally collude piece.

2, by described pair of open end zipper of claim 1, it is characterized in that: the inwall of upper and lower pull head all is plane.

3, by claim 1 or 2 described pairs of open end zippers, it is characterized in that: this laterally colludes the end that piece is arranged on close left plug-in unit or right plug-in unit.
