2. The resin zipper is characterized in that teeth are matched with polyester plastic rice through dye and discharged through an injection molding machine.

3. The zipper is made by fixing and arranging polyester monofilaments on the edges of cloth belts through molding and other processes.

In the prior patent, CN210018100U discloses a reinforced zipper tooth strip and a reinforced zipper, wherein a cloth belt or cloth and the reinforced zipper tooth strip are fixedly sewn through a thread groove and a sewing thread to form a zipper tooth belt, so that the strength of the whole reinforced zipper is higher, and zipper teeth cannot easily fall off, thereby prolonging the service life of the zipper.

The zipper produced by the process is thicker in the thickness of the zipper tooth part by combining the patent figure 2 and practical operation, so that the zipper is too thick and heavy, the light and thin effect cannot be reasonably realized, and the application range of the zipper is effective.

SUMMERY OF THE UTILITY MODEL

The zipper is strengthened to the resin, and the utility model aims to provide a zipper is strengthened to this resin can reduce chain tooth position thickness for zipper application scope is wider.

In order to achieve the above purpose, the utility model provides a following technical scheme: a resin reinforced zipper comprises base cloth, a zipper tooth strip and a pull head, wherein the zipper tooth strip comprises a plurality of zipper tooth blocks, each zipper tooth block comprises a zipper tooth seat and an engaging end, and the engaging end is arranged on one side of each zipper tooth seat;

the chain tooth seat is provided with an injection molding part;

the upper end of the chain tooth seat is provided with a wire groove.

To sum up, the utility model discloses following beneficial effect has: 1. the thickness of the injection molding chain tooth strip is far smaller than that of the chain tooth strip with the cloth seam cavity after oppositely folded, so that the zipper is reduced, the application range is wider, and the appearance is more attractive.

2. Through twice fixing, the connection strength between the zipper tooth strips and the base cloth is more remarkable, the strength of the whole reinforced zipper is higher, and the zipper teeth cannot easily fall off, so that the service life of the zipper is prolonged.

fig. 2 is an enlarged schematic view of a.

Reference numerals: 1. a base cloth; 2. a chain tooth bar; 3. a chain tooth block; 4. a chain tooth seat; 5. an engagement end; 51. an engaging projection; 52. an engagement recess; 6. a wire slot; 7. and a connecting end.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1 and 2, in order to achieve the above object, the present invention provides the following technical solutions: a resin reinforced zipper comprises base cloth 1, a zipper tooth strip 2 and a pull head, wherein the zipper tooth strip 2 comprises a plurality of zipper tooth blocks 3, each zipper tooth block 3 comprises a zipper tooth seat 4 and an engaging end 5, and the engaging end 5 is arranged on one side of the zipper tooth seat 4;

the chain tooth seat 4 is provided with an injection molding part;

the upper end of the chain tooth seat 4 is provided with a wire casing 6.

The utility model discloses a design, 2 injection moulding of chain tooth strip are on base cloth 1, then carry out the secondary and consolidate to chain tooth strip 2 through wire casing 6 and connection rope, finally form fixed effect.

The present application has the benefits over prior art patents:

1. injection moulding's chain tooth strip 2, its thickness is far less than the chain tooth strip 2 that has the cloth seam chamber after the fifty percent discount in opposite directions for self zip fastener reduces, and application scope is wider, and is more pleasing to the eye.

2. Through twice fixing, the connecting strength between the zipper tooth strips 2 and the base cloth 1 is more obvious, the strength of the whole reinforced zipper is higher, the zipper teeth cannot easily fall off, and the service life of the zipper is prolonged.

The side of the chain tooth base 4 away from the engaging end 5 is provided with a connecting end 7.

The connecting end 7 comprises a through hole and a connecting line which are arranged on the chain tooth seat 4.

The connection strength between each element block 3 is reinforced by the connecting line and the through hole.

The wire groove 6 extends along the arrangement direction of the fastener element blocks 3.

A friction layer is arranged in the wire groove 6.

The design of the friction layer is convenient for binding the rope in the connection stage, avoids the rope from shifting in the connection stage and avoids the rope from separating from the wire slot 6.

And the fixing effect of the rope can be improved subsequently.

A plurality of groups of through holes are arranged on the base cloth 1 at equal intervals.

The engaging end 5 includes an engaging convex portion 51 and an engaging concave portion 52.

The engaging recess 52 is provided with two portions in the thickness direction of the element seat 4, a partition plate is provided between the two engaging recess 52, and the engaging projection 51 is provided with two portions in the thickness direction of the element seat 4 for fitting into the adjacent engaging recess 52, respectively.
