Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific examples.

Referring to fig. 1 and 2, fig. 1 is a structure diagram of a zipper according to an embodiment of the present invention; FIG. 2 is a cross-sectional view of the fastener element of FIG. 1 shown engaged.

The embodiment of the invention discloses a zipper, which comprises a cloth belt 1 and a plurality of zipper teeth 2, wherein the cloth belt 1 comprises a tooth implanting area 11 and a sewing area 12, the tooth implanting area 11 is used for implanting the zipper teeth 2, the sewing area 12 is used for being sewn on a fabric 01, and the tooth implanting area 11 and the sewing area 12 are woven together. The thread density of the tooth implanting area 11 is greater than that of the sewing area 12, so that the tooth implanting area 11 is prevented from being damaged by the zipper teeth 2, and meanwhile, the sewing area 12 is softer than the tooth implanting area 11, and the cloth belt 1 can be effectively prevented from arching.

Wherein, strap 1 specifically is flexible strap, can effectively prevent strap 1 arch camber.

Plant tooth district 11 and keep away from one side of making up district 12 and weave heart yearn 13, usable inkle loom parcel lives heart yearn 13, and whole chain teeth 2 are evenly planted on heart yearn 13 along the linear, and the line diameter of heart yearn 13 is greater than the thickness of strap 1, and heart yearn 13 is outstanding, makes chain teeth 2 fixed more reliable, and the interlock power between the interlock chain tooth 2 is stronger, and connection reliability is higher.

Specifically, the fastener element 2 is fixed to the tooth implanting region 11 by injection molding.

When in sewing, the two sides of the fabric 01 clamp the sewing area 12 for sewing, the width of the sewing area 12 is equal to the width of the single-side presser foot, the cloth belt 1 is tightly combined with the fabric 01, the exposed sewing area 12 can not be seen almost, the effect of no cloth belt is achieved, the color difference between the exposed cloth belt 1 and the fabric 01 is eliminated, and the attractive appearance is good.

Specifically, the width of the sewing area 12 ranges from 3 mm to 5mm, and the width can be set according to the width of the single-side presser foot at present.

In conclusion, the zipper provided by the invention has higher connection reliability and better aesthetic property.

Besides the fixing of the zipper teeth 2 by the core wires 13, the tooth implanting area 11 is provided with the suture 3, the suture 3 passes up and down the tooth implanting area 11, the suture 3 is alternately wound on each zipper tooth 2, the zipper teeth 2 are further fixed by the suture 3, the biting force of the zipper teeth 2 is further improved, and the connection reliability of the zipper is further improved.

Furthermore, a wire accommodating groove 21 is formed at the tail part of each zipper tooth 2, and the wire accommodating groove 21 is used for accommodating the suture 3, so that the suture 3 is prevented from being separated from the zipper tooth 2, and the reliability can be improved. The line-accommodating groove 21 is an annular groove, but is not limited thereto.
