Description

A kind of plastic-steel chain tooth

Technical field

This utility model relates to a kind of slide fastener, and the chain teeth structure particularly relating to slide fastener improves.

Background technology

Delrin zippers with pulllers develops decades, and chain tooth engagement system all never has change, and whole delrin zippers with pulllers product is not People the most constructively cannot be allowed to feel, and new meaning, class sense do not increase, and the horizontal drawing of delrin zippers with pulllers strength and warpage intensity also one Directly cannot get a promotion.

Utility model content

The purpose of this utility model is to solve the problems of the prior art, it is provided that the plastic-steel chain that a kind of tailored appearance is generous Tooth.This plastic-steel chain tooth not only tooth body is less, and materials more save, light weight, and have more excellent bending motility and pliability.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

A kind of plastic-steel chain tooth, described chain tooth includes the left and right intermeshing engaging piece of chain tooth and the tooth being fixed on strap Root；The upper field of conjugate action of described engaging piece is provided with the first engagement projections and the first engagement recess, and the lower field of conjugate action of described engaging piece sets The second engagement recess and the second engagement projections, described first and second engagement projections, first and second engagement recess is had to interlock respectively and set Put on the upper and lower field of conjugate action, so that during the engagement of upper and lower adjacent chain tooth, the first engagement projections engages the second engagement recess, and first nibbles Close recess and engage the second engagement projections.

A kind of plastic-steel chain tooth as above, described first engagement projections is wide with the first engagement recess, and described second nibbles Close recess and the second engagement projections is wide.

A kind of plastic-steel chain tooth as above, each end face of described root of the tooth is flat face；Described first and second engagement projections For protruding the projection that the upper and lower end face of root of the tooth is arranged, described first and second engagement recess is to form the deep gouge of breach for sidepiece, and this sinks The notch of groove end face upper and lower with root of the tooth is concordant.

Plastic-steel chain tooth as above a kind of, the outer face of described projection be formed at the breach of deep gouge all with root of the tooth before Rear end face is concordant.

Having the beneficial effect that of technique scheme

This utility model chain tooth is by being crisscross arranged in first and second engagement projections of the upper and lower field of conjugate action and first and second engagement Recess so that during the engagement of upper and lower adjacent chain tooth, the first engagement projections is corresponding with the first engagement recess engage the second engagement recess and Second engagement projections, to ensure chain tooth para-position accurate after slide fastener engagement, flatwise tensile strength promotes, and provides and brand-new pull hands Sense, and bring the General Promotion of delrin zippers with pulllers class sense.

First and second engagement of the root of the tooth combination protrusion upper and lower end face of root of the tooth that each end face of this utility model is flat face is convex Portion, with notch, first and second engagement recess of the concordant setting of breach end face upper and lower with root of the tooth, makes these plastic-steel chain toilet article have the simplest Clean smooth outward appearance, and the tooth body that volume is less.Less tooth body makes the pliability of slide fastener more preferably, and chain tooth can be made more dense Arrangement, promote further the flatwise tensile strength of slide fastener.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, with Under in conjunction with the accompanying drawings and embodiments, this utility model is further elaborated.Should be appreciated that concrete reality described herein Execute example only in order to explain this utility model, be not used to limit this utility model.

A kind of delrin zippers with pulllers as shown in Fig. 1,2,5,6, the plastic-steel chain tooth chain tooth of this slide fastener includes that left and right chain tooth is mutually nibbled The engaging piece 20 closed and the root of the tooth 30 being fixed on strap 10.

As Figure 1-4, the upper field of conjugate action 21 of described engaging piece 20 is provided with the first engagement projections 21A and the first engagement recess 21B, the lower field of conjugate action 22 of described engaging piece 20 is provided with the second engagement recess 22B and the second engagement projections 22A.And as shown in Figure 4, Described first engagement projections 21A and the first engagement recess 21B are wide, described second engagement recess 22B and the second engagement projections 22A Wide.

The first engagement projections 21A as shown in Figure 1, 2 and the second engagement projections 22A shift to install the upper and lower field of conjugate action 21, On 22, the first engagement recess 21B and the second engagement recess 22B shift to install on the upper and lower field of conjugate action 21,22, to form first, Two engagement projections 21A, 22A, what first and second engagement recess 21B, 22B were crisscross arranged respectively on the upper and lower field of conjugate action 21,22 divides Cloth state, so that during the engagement of upper and lower adjacent chain tooth, as shown in Figure 5,6, the first engagement projections 21A engagement cochain tooth of lower chain tooth D Second engagement recess 22B of C, second engagement projections 22A of the first engagement recess 21B engagement chain tooth C of lower chain tooth D.This practicality The engagement system that Novel plastic-steel chain toilet article are the same just like metal tooth, after not only guarantee slide fastener engages, chain tooth para-position is accurate, flat Tensile strength promotes, and provides the brand-new feel that pulls, and brings the General Promotion of delrin zippers with pulllers class sense.

As shown in figures 1 to 6, each end face of this utility model root of the tooth 30 is flat face, described first and second engagement projections 21A, 22A are to protrude the projection that the upper and lower end face of root of the tooth 31,32 is arranged.End face 33 before and after the outer face of this projection and root of the tooth 30 Concordant.Described first and second engagement recess 21B, 22B are the deep gouge that sidepiece forms breach, the notch of this deep gouge and root of the tooth upper and lower end Face 31,32 is concordant, and the breach being formed at deep gouge sidepiece is concordant with end face before and after root of the tooth 33, so that these plastic-steel chain toilet article have more The most smooth outward appearance, and the tooth body that volume is less, less tooth body makes the pliability of slide fastener more preferably, and can make chain Ya Gengmi The arrangement of collection, promotes the flatwise tensile strength of slide fastener further.

Description above describe preferred embodiment of the present utility model, it is to be understood that on this utility model is not limited to State embodiment, and should not regard the eliminating to other embodiments as.By enlightenment of the present utility model, those skilled in the art combine The change that known or prior art, knowledge are carried out also should be regarded as in protection domain of the present utility model.
