Abstract

The utility model provides a slide fastener teeth, comprises teeth arranged at the inner side of cloth of two fasteners, and is characterized in that the cross section of the teeth is a long oval formed by central thickness respectively and gradually contracted to two sides, and the top is provided with a support rod respectively and inwardly protruded and extended. The central parts of the two outer edges of the support rod are respectively provided with a concave arc-shaped embedding groove, and the edge of the support rod is provided with an upper convex wing and a lower convex wing which extend to the two sides in a winding manner, while an arc-shaped cone formed by the gradual contraction of the thickness of the tail end of the upper and lower convex wings is fixedly connected with the concave arc-shaped embedding groove positioned on the central parts of the two outer edges of the support rod protruded and extended from the top of two adjacent teeth positioned at the inner side of the cloth of the other fastener. The utility model solves the technical problem of the separation of the slide fastener teeth caused by an improper external force after being closed.

Description

Zipper teeth

Technical field:

The utility model is about slide fastener, particularly about a kind of zipper teeth that increases its vertical, horizontal and the nested adaptation of above-below direction.

Background technology:

Present dealer commonly uses slide fastener for improvement and is subjected to easily producing intermeshing zipper sprocket separation behind the lateral pull, so create a kind of metal zip fastener tooth, each zipper teeth 10E on two row tooth rows, the meshing end of 10B (see figure 1) top is extended with flange 12E, 12B, flange 12E, 12B respectively digs the bottom and is provided with embeded slot 120E, 120B, can be along with the displacement of a nylon pull head G, make mutual corresponding zipper teeth 10E, the flange 12E of 10B, 12B, embeded slot 120E, 120B is engaged with or opens, but when be subjected to lateral pull F or produce improper, problems such as raw material hardness, the zipper teeth 10E that it is mutually nested, 10B easily each outwards move and separate or on set aside from, reduce its utilization rate.

That shown in Figure 2 again is the slide fastener H that another kind of both sides are provided with zipper teeth H1, H2 with projection respectively.As if engagement of zipper teeth H1 and H2 when closure, but when be subjected to lateral pull or improper external impacts, then each outwards moves and makes separation therebetween easily for two zipper teeth H1, H2; Middle each the tip-tilted situation of its two zipper teeth H1, H2 that is that Fig. 3 disclosed.

Summary of the invention:

The utility model provides a kind of zipper teeth, to produce the technical problem that zipper teeth is separated because of improper power after the drawing of solution slide fastener.

A kind of zipper teeth, comprise the sprocket that is arranged on two slide fastener selvedge inboards, it is characterized in that: this sprocket section is that each tapers to oblong to both sides by central thickness, each the inside projection of its top has pole, the arcs of recesses caulking groove is respectively established in the middle part of pole two lateral borders, respectively prolong by the pole rim the more upper and lower protruding wing is arranged to two lateral bendings, and upper and lower protruding wing end thickness is established curved taper gradually, and is nested fixed with the arcs of recesses caulking groove of the pole two lateral border middle parts of inboard adjacent two the sprocket top projections of another slide fastener selvedge.

The utility model is because the upper and lower protruding interplane nested adaptation that is formed with on any direction of intermeshing sprocket, make between the zipper sprocket of mutual engagement and can not separate because of the external force torque forces is excessive, improper, and make slide fastener more soft, so prolong the service life of slide fastener, have economic benefit and practicality.

The specific embodiment:

For making the more obvious performance of the utility model, now be described in detail in conjunction with the accompanying drawings.

At first see also Fig. 4, Fig. 5, shown in Figure 6, the utility model is respectively to be provided with sprocket 2,3 in two slide fastener selvedges, 1,10 inboards.This each inside projection of sprocket 2,3 tops has pole 20,30, and spill caulking groove 200,300 is respectively established in the middle part of 20,30 liang of lateral borders of pole, and respectively being prolonged to two lateral bendings by pole 20,30 rims has the upper and lower protruding wing 21,22,31,32 again.Because sprocket 2,3 structures are identical, existing is that example awards explanation with sprocket 2 only.Sprocket 2 sections of this slide fastener selvedge 1 inboard as shown in Figure 5, each tapers to oblong to both sides by central thickness, and the upper and lower protruding wing 21,22 is arranged in the both sides projection, the upper and lower protruding wing 21, the 22 end thickness curved taper 210,220 that contracts gradually, nested fixed with the arcs of recesses caulking groove 300 of the pole 30 pairing lateral border middle parts of two adjacent sprocket 3 top projections of another slide fastener selvedge 10 inboards.The upper and lower protruding wing 21,22 ends by sprocket 2 respectively are provided with arc taper 210,220, and the following protruding wing 32, the epirelief wing 31 that are engaged with two corresponding sprockets 3 form nested engagement (as Fig. 4,6 announcements).In like manner, the upper and lower protruding wing 31,32 of sprocket 3 end separately is provided with taper, the arcs of recesses caulking groove 200 nested engagements of this taper of mat and corresponding two adjacent sprockets 2.21,22,31,32 on the upper and lower protruding wing of the sprocket 2,3 of engagement is formed with arbitrarily to nested adaptation.

Shown in Figure 7, be the sprocket 2,3 of the utility model design to be made with the slide fastener selvedge 1,10 of its bottom combine; Or as shown in Figure 8 slide fastener selvedge 1,10 directly is inserted between sprocket 2,3; Make sprocket 2,3 form different syndetons with slide fastener selvedge 1,10.

Claims (1)

1, a kind of zipper teeth, comprise and be arranged on two slide fastener selvedges (1), (10) Nei Ce sprocket (2), (3), it is characterized in that: this sprocket (2), (3) section is that each tapers to oblong to both sides by central thickness, each the inside projection of its top has pole (20), (30), pole (20), arcs of recesses caulking groove (200) is respectively established in the middle part of (30) two lateral borders, (300), again by pole (20), (30) rim each to two lateral bendings prolong have on, the following protruding wing (21), (22), (31), (32), and on, the following protruding wing (21), (22), (31), (32) end thickness is established curved taper (210) gradually, (220), nested fixed with the arcs of recesses caulking groove (200/300) of pole (20/30) the two lateral border middle part of inboard adjacent two sprockets (2/3) the top projection of another slide fastener selvedge (1/10).
