Abstract

An improved zipper comprises two cloth strips, zipper teeth and a zipper head, wherein the zipper teeth are respectively sewn on the two cloth strips and are mutually meshed, and the zipper head is used for controlling the meshing of the zipper teeth, wherein grooves for accommodating sewing threads are arranged in the middle part of the upper surface of the zipper teeth. As the sewing threads are fixed in the grooves, the friction of the sewing threads and the zipper head can be avoided, the connecting strength of the cloth strips and zipper teeth is also increased, and the improved zipper is very practical.

Description

A kind of improved slide fastener
Technical field
The utility model relates to daily living article, and particularly a kind of sprocket is provided with the improved slide fastener of groove.
Background technology
Slide fastener is a kind of little articles for use commonly used in people's daily life, and it is easy to use, uses very extensive in fields such as clothes manufacturings.The sprocket of existing slide fastener, as shown in Figure 1, make on two cloths through suture; Most of sprocket is the ellipse of surface smoothing,, suture is exposed to the chain tooth surface fully; Pulling is during begin chain, easily with the begin chain friction, makes suture shortening in service life and then cause the whole piece slide fastener to be scrapped.And after the time grown, suture can cause slide fastener unstable because elasticity is loosening to some extent, occurs the situation of engagement dislocation easily, shines into unnecessary trouble to the user.
The utility model content
The suture that the main purpose of the utility model is to overcome on the prior art zipper sprocket is exposed fully outside; Easily because the begin chain friction causes having become flexible, shortened the shortcoming in the life-span of slide fastener, a kind of improved slide fastener that on the chain tooth surface, is provided with the groove that is used to hold suture is proposed.
The utility model adopts following technical scheme:
A kind of improved slide fastener comprises two cloths, makes on two cloths respectively and intermeshing sprocket and being used to is controlled the slider of zipper fastener of sprocket engagement, and it is characterized in that: said sprocket upper surface middle part is provided with the groove that is used to hold suture.
Can know by above-mentioned description the utility model; Compared with prior art; The utlity model has following beneficial effect: the groove that is provided for holding suture in the sprocket upper surface middle part; Suture is played a protective role, can not rub mutually when making the slider of zipper fastener pulling, effectively avoided the damage that suture is caused with suture; Owing to when making suture is fixed in the groove, suture and sprocket firmly are fixed on the cloth, strengthened the connection between sprocket and the cloth, prolonged the service life of slide fastener.The utility model manufacturing process is simple, and cost is low, long service life.
Description of drawings
Fig. 1 is a prior art sprocket sketch map;
Fig. 2 is the utility model sprocket structural representation.
The specific embodiment
Below the utility model is done further to describe through the specific embodiment.
With reference to Fig. 2; A kind of improved slide fastener; Comprise two cloths 1, make on two cloths respectively and intermeshing sprocket 2 and the slider of zipper fastener (figure does not mark) that is used for controlling sprocket 2 engagements; Sprocket 2 upper surface middle part are provided with the groove 4 that is used to hold suture 3, and suture 3 is fixed in the friction that groove 4 places can not only effectively avoid suture 3 and slider of zipper fastener, can also increase the bonding strength between cloth 1 and the sprocket 2.
The above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
