Abstract

The utility model discloses a zip fastener of double -end chain tooth and applied this chain tooth, the chain tooth is including integrative tooth head and the tooth body that sets up, constitution as an organic whole is connected with the tooth body to the left and right tooth head of tooth pretext, and left and right tooth head has certain clearance and sets up, and the lateral border of left and right tooth head is the engaging piece between adjacent chain tooth, the interlock of tooth body is on the strap. The upper portion interlock of tooth body is on the cloth muscle of strap, the lower part interlock of tooth body is on the body of strap, the tooth outside ora terminalis of portion on one's body is wideer than the outside ora terminalis of tooth body lower part. The utility model discloses the material of zip fastener uses still less, and the cost is lower, and has ventilatively and the good advantage of compliance.

Description

A kind of double end chain tooth and apply the slide fastener of this chain tooth

Technical field

This utility model relates to a kind of zipper, and the structure especially relating to chain tooth is improved.

Background technology

At present, the innovation of slide fastener is more to consider chain tooth and strap bond strength.But along with drawing The expansion of chain range of application, people are to personalized requirement, and the reinforcement of environmental consciousness, slide fastener Except, in addition to the innovation in terms of Performance Strength, energy-conservation and applicable range the most gradually becoming zipper industry Research Emphasis.

Utility model content

For problems of the prior art, this utility model provides a kind of double end chain tooth and answers With the slide fastener of this chain tooth, the materials'use of this slide fastener is less, and cost is lower, and have ventilative and The advantage that pliability is good.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of double end chain tooth and apply the slide fastener of this chain tooth, described chain tooth includes the tooth being wholely set Head and tooth body；Described tooth head is connected as one with tooth body by left and right tooth head and forms, left and right tooth Head has certain interval and arranges, and the lateral border of left and right tooth head is the engaging piece between adjacent chain tooth； Tooth body is engaged on strap.

A kind of double end chain tooth as above and apply the slide fastener of this chain tooth, the top of described tooth body Being engaged on the cloth muscle of strap, the bottom of described tooth body is engaged on the body of strap；Described tooth The outside ora terminalis of body is wider than the outside ora terminalis of tooth body bottom.

Having the beneficial effect that of technique scheme

The tooth head of chain tooth is designed with the bipitch structure of certain interval by this utility model slide fastener. The gap of this bipitch structure tooth head not only acts as the consumption saving every chain tooth at material, Er Qiezeng The width adding gap also can make the chain tooth number used on same length slide fastener reduce.This gap Design also can make slide fastener more ventilative, particularly suitable at summer clothing or need on ventilated product. The outside ora terminalis of tooth body is designed to wider than the outside ora terminalis of tooth body bottom by this utility model, The pliability of slide fastener can be promoted further.

Accompanying drawing explanation

Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes this A part for utility model, schematic description and description of the present utility model is used for explaining this Utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect more Add clear, clear, below in conjunction with drawings and Examples, this utility model is carried out the most in detail Describe in detail bright.Should be appreciated that specific embodiment described herein only in order to explain this utility model, It is not used to limit this utility model.

A kind of double end chain tooth as Figure 1-5 and apply the slide fastener of this chain tooth, described chain tooth Including the tooth head 10 being wholely set and tooth body 20, described tooth head 10 be adjacent two chain teeth 30, The engaging piece of 40, described tooth body 20 is that chain tooth 30,40 is fixed on the occlusion on strap 50 Portion.

As it is shown in figure 5, the tooth head 10 of described chain tooth is double end tooth head.Specifically, described Tooth head 10 connected as one with tooth body 20 by left and right tooth head 11,12 and form. Described left and right tooth head 11,12 has certain interval 13 and arranges, with in chain tooth is vertical The lateral symmetry of heart line O forms the double end tooth header structure of two separate tooth heads.Left and right tooth The lateral border of 11,12 is the engaging piece between adjacent two chain teeth 30,40, and tooth body 20 is stung It is combined on strap 50.

As shown in Fig. 1,2,4,5, adjacent two chain teeth 30,40 are by left and right tooth head 11, jog A, B correspondence engagement that the lateral border of 12 is provided with, with closed zipper.

The big I in gap 13 between this utility model left and right tooth head 11,12 has according to slide fastener Depending on the product that body is applied to, this gap 13 not only acts as the use saving every chain tooth at material Amount, and the chain tooth number used on same length slide fastener can be made to reduce.Left and right tooth head 11, The design in the gap 13 between 12 also can make slide fastener more ventilative, particularly suitable logical at summer clothing or needs On the product that wind is ventilative.

The tooth body 21 of this utility model chain tooth is engaged on the cloth muscle 51 of strap 50, tooth Body bottom 22 is engaged on the body 52 of strap 50.For promoting the pliability of slide fastener further, As shown in Figure 1, 2, this utility model slide fastener is by described tooth body 21 and tooth body bottom The width design of the outside ora terminalis of 22 becomes small one and large one.Specifically, outside tooth body 21 The side edge width H numerical value than the outside ora terminalis width L of tooth body bottom 22 is big.

Described above illustrate and describes preferred embodiment of the present utility model, as it was previously stated, should When understanding that this utility model is not limited to form disclosed herein, it is not to be taken as other The eliminating of embodiment, and can be used for other combinations various, amendment and environment, and can be herein In described utility model contemplated scope, entered by above-mentioned teaching or the technology of association area or knowledge Row is changed.And the change that those skilled in the art are carried out and change are without departing from spirit of the present utility model And scope, the most all should be in the protection domain of this utility model claims.
