Abstract

The utility model relates to a zipper. According to the zipper, composite dual teeth and dual-plano-concave tooth ways are linked. The zipper comprises a side lining A, composite dual teeth, dual-plano-concave tooth ways and a side lining B, wherein the composite dual teeth are aligned in an upward-downward side-by-side manner, the tail ends of the inner sides of the composite dual teeth are embedded in a left side interlayer of the side lining A and are fixed in a manner that a thread is used for sewing from the outside, a bottom lining is sewn to the reverse side of the side lining A in a manner that the upper and lower side edges of the bottom lining are aligned with the right side edge of the bottom lining, the lower end of a sewn seam of the side lining A and the bottom lining is fixed to the upper end edge of a plug, the dual-plano-concave tooth ways are aligned in an upward-downward side-by-side manner, the tail ends of the inner sides of the dual-plano-concave tooth ways are embedded in a right side interlayer of the side lining B and are fixed in a manner that a thread is used for sewing from the outside, a bottom lining is sewn to the reverse side of the side lining B in a manner that the upper and lower side edges of the bottom lining are aligned with the left side edge of the bottom lining, the lower end of a sewn seam of the side lining B and the bottom lining is fixed to the upper part edge of the plug, and an adapting part at the lower part of the plug is inserted and fixed at a left adapting position at the upper side of a plug bush.

Description

A kind of slide fastener

Technical field

The utility model relates to a kind of slide fastener, relates in particular to a kind of slide fastener that utilizes compound bidentate and two plano-concave tooth roads to be connected mutually.

Background technology

At present, known slide fastener adopts monodentate, single plano-concave tooth road body plan, because tooth and tooth road are tiny intensive, cause serobila to be connected ineffective, often disconnect, slip off, main is, the part can appear in the tooth of slide fastener and tooth road drops, and wears off clothes to people and has brought very big puzzlement.

Summary of the invention

In order to overcome existing slide fastener existing deficiency in use, the utility model provides a kind of slide fastener, and this slide fastener adopts compound bidentate and two plano-concave tooth road body plans, not only easily be connected, and firm and durable.

The technical scheme that its technical problem that solves the utility model adopts is: comprise limit lining cloth A, compound bidentate, two plano-concave teeth road, limit lining cloth B, compound bidentate and compound bidentate up and down between flat raft align, in the left side interlayer of inboard terminal built-in edges lining cloth A, and make fixing from the outside by line, both sides are along the joining edge lining cloth A reverse side that aligns with the edge, right side about the end liner cloth, end liner cloth left side adapts to the position along extending to compound bidentate, the lower end that plug upper end edge fixed edge lining cloth A and end liner cloth are sewed up, flat raft alignment between about two plano-concave tooth Lu Yushuan plano-concave teeth road, in the right side interlayer of inboard terminal built-in edges lining cloth B, and make fixing from the outside by line, both sides are along the joining edge lining cloth B reverse side that aligns with the edge, left side about the end liner cloth, end liner cloth right side adapts to the position along extending to two plano-concave tooth roads, adapt to the position below the lower end that plug top fixed edge lining cloth B and end liner cloth are sewed up, plug and inject and be fixed on left side adaptation place of sleeve upside.

The beneficial effects of the utility model are, because both sides have been adopted bidentate binary and wide plano-concave tooth line structure respectively, have increased length, width, the thickness of tooth, also open up simultaneously dark, widened the tooth road, linking easily more has dynamics, more smooth between two bodies after the linking.
