Abstract

The utility model relates to zip technical field, in particular to a new zip sprocket easy to use and firmly interlocking with cloth belt. The utility model has zip feet at two sides of the rear end of the zip body and interlocking with the cloth belt; the front side of the upper end of the zip body has raised points; raised teeth corresponding to each other are positioned respectively at the zip feet and the internal side. By adopting the technical proposal, the raised teeth correspondingly formed at the internal side of the zip teeth can interlock the cloth belt closely and increase the interlocking of the zip teeth to the cloth belt, thereby increasing the fastness of the zip teeth.

Description

A kind of novel zipper tooth

Technical field:

The utility model relates to the slide fastener technical field, refer in particular to a kind of easy to use, with the firm novel zipper tooth of strap interlock.

Background technology:

Slide fastener is a kind of widely used article in daily life, the sprocket of slide fastener is that the mutual interlock by the chain pin of both sides, its rear end and strap is fixed on the strap, from present operating position, the firm degree of this combination is not very reliable, occur the situation that sprocket is crooked even come off easily, make the whole piece slide fastener to use.

Summary of the invention:

The purpose of this utility model promptly is to provide a kind of sprocket that makes to combine more reliable sprocket with cloth at the weak point of existing zipper sprocket.

For achieving the above object, the utility model holds both sides to form chain pin with the interlock of strap cloth muscle at chain after one's death, and the front side, upper surface of chain body forms salient point, and the lower surface of chain body forms pit over against the position of salient point.Chain pin and the inboard relative double wedge in position that then forms respectively.

As a kind of improvement of the present utility model, form the breach that cooperates with pull head respectively on the left and right sides end face of chain body.

After adopting technique scheme, the relative double wedge in position that is molded over chain pin inboard can tightly be bitten the cloth muscle of strap, strengthens the adhesive force of sprocket on strap, thereby increases the firm degree of sprocket.

Resistance when being molded over the breach that cooperates with pull head on the left and right sides end face of chain body respectively and then can reducing the pull head drawing, it is light sliding smooth and easy to make that pull head draws when opening.

Description of drawings:

Accompanying drawing 1 is the utility model perspective view

Accompanying drawing 2 is the perspective view at another visual angle of the utility model

Accompanying drawing 3 is user mode figure of the present utility model

The specific embodiment:

See shown in the accompanying drawing 1～3, the utility model comprises chain body 10, both sides, chain body 10 rear end form the

chain pin

11 and 12 with strap 20 interlocks, and the front side, upper surface of chain body 10 forms salient point 13, and chain pin 11 forms the relative double wedge in position 111 and 121 respectively with 12 inboards; Form the

breach

14 and 15 that cooperates with pull head on the left and right sides end face of chain body 10 respectively; The lower surface of chain body 10 forms pit 16 over against the position of salient point 13.

During use, the double wedge 111 that chain pin 11 is relative with 12 inner sides and 121 can be wrapped the cloth muscle 21 of strap 20, bites cloth muscle 21 tightly, makes sprocket very firm with combining of strap 20, basically the situation that sprocket is crooked and come off can not occur, thereby increase the service life of slide fastener.

Claims

1. novel zipper tooth, comprise chain body (10), chain body (10) both sides, rear end form chain pin (11) and (12) with the interlock of strap cloth muscle, the front side, upper surface of chain body (10) forms salient point (13), the lower surface of chain body (10) forms pit (16) over against the position of salient point (13), it is characterized in that: chain pin (11) and (12) the inboard relative double wedge in position (111) and (121) of forming respectively.

2. zipper sprocket according to claim 1 is characterized in that: form the breach (14) and (15) that cooperate with pull head on the left and right sides end face of chain body (10) respectively.
