Abstract
The invention relates to a metal pinion, which comprises a pair of tooth feet, wherein the tooth feet are mutually matched and occluded on a belt root of a zipper woven belt and have different lengths. On a metal zipper which is assembled with the metal pinion, the zipper woven belt can be shielded by the longer tooth foot so as to prevent the zipper woven belt from being abraded by a zipper head.
Description
Technical field
The present invention relates to a kind of metal sprocket and the metal zip fastener of being furnished with this metal sprocket, belong to the manufacturing technology field of metal zip fastener.
Background technology
My unit has developed a kind of trendy metal zip fastener, and the chain strap of this slide fastener is made of band root and band skirt surrounding edge, and sprocket is arranged on the baes position of chain strap, and band skirt surrounding edge is arranged on the below of sprocket, and it is folded to form the first band skirt surrounding edge and the second band skirt surrounding edge.The first band skirt surrounding edge is stitched together by suture and sprocket, has strengthened the firmness of slide fastener so greatly, can bear bigger horizontal power.
But the sprocket of the slide fastener of this spline structure and part chain strap just can be given prominence to the chain strap, following problem can occur when work: the tooth pin of sprocket and chain strap band root junction just can suffer the friction of slider of zipper fastener, so just, can damage slide fastener, bring the certain quality problem to slide fastener.
Summary of the invention
Technical problem to be solved by this invention provides a kind of metal sprocket that can prevent slider of zipper fastener wearing and tearing chain strap, and this metal sprocket can be hidden in the chain strap sprocket bottom, avoids the wearing and tearing of slider of zipper fastener.Simultaneously, the present invention also provides a kind of metal zip fastener that is equipped with above-mentioned sprocket.
In order to solve above-mentioned technical problem, technical solution of the present invention is: a kind of metal sprocket, comprise a pair of tooth pin, and the tooth pin cooperatively interacts on the band root that is engaged in the chain strap, and described a pair of tooth pin pin length differs.
A kind of metal zip fastener, comprise metal sprocket and chain strap, the chain strap is made of band root and band skirt surrounding edge, described metal sprocket is arranged on the baes position of chain strap, described band skirt surrounding edge is arranged on the below of metal sprocket, it is folded to form the first band skirt surrounding edge and the second band skirt surrounding edge, the described first band skirt surrounding edge lumps together by suture and metallic bond slot, described metal sprocket comprises a pair of tooth pin, the tooth pin cooperatively interacts on the band root that is engaged in the chain strap, described a pair of tooth pin pin length differ and the tooth pin of the band skirt surrounding edge contact side of chain strap shorter than another tooth pin.
The tooth pin of the long part of the metal zip fastener of said structure is positioned at top, and the chain strap just can be blocked by the long tooth pin in top like this, has avoided the chain strap to suffer the wearing and tearing of slider of zipper fastener, has guaranteed the quality of slide fastener.
Description of drawings
Fig. 1 is the structural representation of metal sprocket of the present invention.
Fig. 2 is the structural representation of metal zip fastener of the present invention.
The specific embodiment
As shown in Figure 1, metal sprocket 1 of the present invention comprises a pair of tooth pin 7, and tooth pin 7 cooperatively interacts on the band root that is engaged in the chain strap, and described a pair of tooth pin 7 pin length differ.
A kind of metal zip fastener as shown in Figure 2, comprise metal sprocket 1 and chain strap 2, chain strap 2 is made of band root 3 and band skirt surrounding edge, described metal sprocket 1 is arranged on band root 3 places of chain strap 2, described band skirt surrounding edge is arranged on the below of metal sprocket 1, it is folded to form the first band skirt surrounding edge 4 and the second band skirt surrounding edge 5, and the described first band skirt surrounding edge 4 is stitched together by suture 6 and metal sprocket 1.
Band root 3 parts of the metal sprocket 1 of the slide fastener of said structure and chain strap 2 just can be given prominence to chain strap 2, and as shown in Figure 2, the tooth pin 7 of metal sprocket 1 just can suffer the friction of slider of zipper fastener with chain strap 2 band roots 3 junctions like this, causes the damage of chain strap 2.
After adopting the metal sprocket 1 of said structure, chain strap 2 just can be blocked by the long tooth pin 7 in top, has avoided chain strap 2 to suffer the wearing and tearing of slider of zipper fastener.
