Abstract
The utility model relates to zip-teeth of zipper comprising a zip-head and a couple of toothed edges. The utility model is characterized in that: the middle parts of the interior laterals of the couple of toothed edges are oppositely provided with positioning pins; the top ends of the couple of toothed edges are inward claw-like; the zip-head whose meshing surface is concave-circle shaped is hemisphere-shaped. The design of the positioning pins of the utility model guarantees the high flatly-fastening strength and the high single-tooth displacement force of the made-up zipper; the concave-circle shaped design of the meshing surfaces of the zip-teeth further guarantees the bending flexibility of the zip chain of the zipper with easily-sliding performance of meshing and splitting, as well as nicely solves the problem of the easily-sliding performance of the fastening and unfastening in the reverse direction.
Description
Technical field
The utility model relates to the architecture advances of slide fastener, the slide fastener coupling element that particularly a kind of flat wire rod that adopts the cross section to be rectangle is made.
Background technology
Slide fastener coupling element has two kinds of Y type tooth and plain edition teeth: existing Y type tooth must adopt the cross section to be Y type shaped wire, via YG type tooth planter through section, dash point and sandwich zipper cloth belt; This chain tooth does not have the tool marks of connecing, and it is spherical that head can be processed into semicircle; Itself and strap junction surface can be designed to Reasonable Shape, to improve flatwise tensile strength and single tooth displacement force.
The flat wire rod that the plain edition tooth adopts the cross section to be rectangle, planting the tooth machined via metal, to make slide fastener monolateral, existing plain edition tooth, the cost of raw material is significantly less than Y type shaped wire, metal is planted the simple in structure of tooth machine, but because the restriction of processing technology, the boss surface of chain tooth head is smooth inadequately; And itself and strap junction surface are subjected to the restriction of nose shape, make flatwise tensile strength and the single tooth displacement force of making slide fastener be difficult to reach industry standard;
Though Y type tooth has improved anti-pulliing strength and single tooth displacement force to a certain extent,, the cost of Y type shaped wire is very high, and the flexible flexibility of the chain of making is poor, and the light slippery of its reverse drawing is not good.
The utility model content
The purpose of this utility model is, overcome Y type chain tooth cost of manufacture height, the limitation of common chain tooth on flatwise tensile strength and single tooth displacement force, and flexible flexibility is poor, the not good defective of light slippery of reverse drawing, thus a kind of slide fastener coupling element that adopts flat wire rod to make is provided.
The technical solution of the utility model provides a kind of slide fastener coupling element, comprises head and a pair of tooth portion, it is characterized in that: described a pair of tooth portion middle inside also correspondence is provided with pilot pin.Like this, the slide fastener flatwise tensile strength height of making, single tooth displacement force height.
As a kind of improvement of the present utility model, the top of described a pair of tooth portion is claw-like in opposite directions, with further raising slide fastener flatwise tensile strength height, single tooth displacement force.
As another improvement of the present utility model, it is spherical that the boss of described head is semicircle, and its field of conjugate action is recessed circle.
The utility model has the advantages that: the slide fastener cost that slide fastener coupling element of the present utility model is made is low, the flatwise tensile strength height, single tooth displacement force height, and the recessed circular design of its field of conjugate action, the chain of the slide fastener that assurance is made is crooked soft, engagement, to separate light slippery good, and solved the problem of the light slippery of reverse drawing well.

The specific embodiment
Below just specify a preferred embodiment of the present utility model in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, the boss 3 of the head 1 of slide fastener coupling element is semi-round ball, and its field of conjugate action 4 is recessed circle; The top 5 of a pair of tooth portion 2 of chain tooth is claw-like in opposite directions, and its middle inside also correspondence is provided with pilot pin 6.
The structure of the slide fastener coupling element of present embodiment can adopt flat wire rod to make, at first cut edge and form the outer shape of chain tooth, and after its head dashes some formation boss, directly hit in the centre position of tooth portion symmetry, the shape of hitting reasonable in design is to form a pair of tooth portion that has pilot pin.The utility model can adopt flat wire rod to make slide fastener coupling element, and the cost of raw material is low.
