Fig. 2 is the cross-sectional view of the single sprocket of the chain tooth bar of double-deck Strong zip fastener of the present utility model.
Detailed description of the invention
In order more clearly to set forth the utility model, below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figures 1 and 2, the utility model provides a kind of double-deck Strong zip fastener and zipper sprocket thereof, described double-deck Strong zip fastener comprises two slide fastener chain cloth 1,2, is sutured in chain tooth bar on two slide fastener chain cloth 1,2 and for impelling the slider of zipper fastener (scheming not shown) of the phase interlock of chain tooth bar or separation respectively, the upper and lower two sides, corresponding lateral margin place of described two slide fastener chain cloth 1,2 are all sewed with chain tooth bar (figure do not indicate), and the chain tooth bar being sutured in respectively in the corresponding side surface of two slide fastener chain cloth 1,2 lateral margins is realized synchronous interlock or separation by described slider of zipper fastener.
The structure of chain tooth bar that described correspondence is sutured in a lateral margin place of slide fastener chain cloth 1,2 is identical, be plastic strip continuous reeling and form sprocket rectangular of multiple helix rounds, but two chain tooth bars is that symmetry is sutured on slide fastener chain cloth 1,2.Shown in Fig. 2, the concrete structure of sprocket is described as an example of the single sprocket 30 that is sutured in the chain tooth bar on slide fastener chain cloth 1 example, described sprocket 30 comprises and is positioned at a side in order to the bite of interlock each other (figure does not indicate) and for being sutured in the suturing part 32 on slide fastener chain cloth 1, on described each suturing part 32, be equipped with the depressed part that a cross section is W shape, the middle part of depressed part has the projection 34 of protruding to notch direction from bottom land, a suture groove 36 of the each formation of depressed part of protruding both sides.In the time sewing up, the projection 36 in sprocket 30 depressed parts can inlay card in slide fastener chain cloth 1, thereby make corresponding firm be fixed on slide fastener chain cloth 1 of sprocket 30 and be difficult for loosening.
In an embodiment of the present utility model as shown in Figure 1, the upper and lower surface at slide fastener chain cloth 1 one lateral margin places has respectively seamed a chain tooth bar, and the upper and lower surface at slide fastener chain cloth 2 one lateral margin places has also respectively seamed a chain tooth bar, thereby formation double-layered slide fastener, wherein lay respectively at two chain tooth bar interlocks mutually of slide fastener chain cloth 1,2 upper surfaces, and lay respectively at the also interlock mutually of two chain tooth bars of slide fastener chain cloth 1,2 lower surfaces.And, in the time sewing up each chain tooth bar, make the depressed part of the sprocket of the chain tooth bar of described each slide fastener chain cloth 1,2 lateral margin place one side surface be arranged at the side surface (arranging) that this sprocket deviates from slide fastener chain cloth outwardly, and the sprocket depressed part of the chain tooth bar on slide fastener chain cloth 1,2 opposite side surfaces, lateral margin place is arranged at the side surface (inwardly arrange) of this sprocket towards slide fastener chain cloth, and the protruding inlay card at depressed part middle part enters slide fastener chain cloth 1,2.In the embodiment shown in fig. 1, to make the depressed part of the sprocket 30,40 of the chain tooth bar of being located at described each slide fastener chain cloth 1,2 lateral margin place downside surface be arranged at the side surface that this sprocket 30,40 deviates from slide fastener chain cloth 1,2, and sprocket 60,70 depressed parts of being located at the chain tooth bar of slide fastener chain cloth 1,2 uper side surfaces are arranged at the side surface of this sprocket 60,70 towards slide fastener chain cloth 1,2, and projection 64,74 inlay cards at depressed part middle part enter slide fastener chain cloth 1,2.By design like this, in the time sewing up, projection 64,74 inlay cards are in slide fastener chain cloth 1,2, and the chain tooth bar of slide fastener chain cloth 1,2 lateral margin place uper side surfaces can be fixed on accordingly on slide fastener chain cloth 1,2 and be difficult for loosening.And suture 8 can be positioned well by each suture groove 36,46 of the sprocket 30,40 of slide fastener chain cloth 1,2 lateral margin place uper side surfaces, and the chain tooth bar of slide fastener chain cloth 1,2 lateral margin place downside surfaces also can be well fixed.Thereby make not cracky of slide fastener, the performance of especially anti-lateral pull is greatly improved.
