Abstract

The utility model discloses a structure for fixing teeth of zipper, comprising zipper teeth and fixing ropes. One side of the zipper teeth is provided with through holes, and all zipper teeth form zipper teeth strings by the through holes being inserted and fixed on the fixing ropes. The zipper teeth strings are sewed on zipper cloth edges through the fixing ropes, and the zipper teeth are fixed the fixing ropes by the way of clamping or injection molding. The structure for fixing teeth of zipper of the utility model makes the zipper cloth edges sustain uniform force, and avoids the condition that concentrated position of sustaining force appears zipper teeth shedding or zipper cloth edges broking.

Description

The zipper teeth fixed structure

Technical field:

The utility model relates to a kind of zipper, relates in particular to a kind of zipper teeth fixed structure.

Background technology:

The material of making zipper sprocket has nylon, engineering plastics and metal usually.Fig. 1, Fig. 2 have represented the structure of the slide fastener B that made by engineering plastics.Directly cemented on the slide fastener selvedge B2 with binding agent by the injection molding zipper teeth B1 of engineering plastics, Fig. 2 is the locational profile of A-A in Fig. 1.Fig. 3, Fig. 4 have represented the structure of the slide fastener C that is made of metal.Zipper teeth C1 by the die cast metal moulding is stung admittedly on slide fastener selvedge C2 by occlusal end tightly in the outside, and Fig. 4 has represented the locational section situation of D-D among Fig. 3.No matter above-mentioned illustrated slide fastener is to use the plastic fastener of cementation mode also to be to use the metal zip fastener of stinging solid mode, and its zipper teeth all is that the mode with single zipper teeth is fixed on the slide fastener selvedge.Because the secure bond place area of single zipper teeth and slide fastener selvedge is very narrow, in use in case the slide fastener unbalance stress takes place, the situation that the suffered drawing power of part zipper teeth is concentrated, on the position of this stressed excessive zipper teeth, will cause that zipper teeth comes off, even the situation of pulling open the slide fastener selvedge, thereby cause the damage of slide fastener.

Summary of the invention:

In order to overcome existing slide fastener when the stressed defective that can damage zipper teeth or zipper cloth when concentrated, the utility model provides a kind of zipper teeth fixed structure that has improved, it utilizes static line with the fixing zipper teeth string that forms of all zipper teeth serial connections, and zipper teeth string is integrally made mode on the slide fastener selvedge by this static line, make that the slide fastener selvedge is stressed to be evenly distributed, thereby avoided slide fastener to cause that at stressed concentrated position zipper teeth comes off or damages the situation of slide fastener selvedge.

The utility model solves the problems of the technologies described above the technical scheme of being taked, a kind of zipper teeth fixed structure, form by zipper teeth and static line, one side of this zipper teeth is provided with perforation, all zipper teeth seal in and are fixed on the described static line to form zipper teeth string with this perforation, and this zipper teeth string is made on the slide fastener selvedge by static line.

The zipper teeth of zipper teeth fixed structure described in the utility model can be provided with the clamping end and grip static line in its side with perforation, thereby zipper teeth is fixed on the static line; Described zipper teeth also can be fixed on the static line by shot molding mode, forms one with static line; Described each zipper teeth equidistantly is being distributed on this static line; Described zipper teeth is made by metal material or engineering plastics.

Compared with prior art, the beneficial effects of the utility model are, described zipper teeth fixed structure takes to be provided with the mode of static line, with the fixing zipper teeth string that forms of single zipper teeth serial connection, and zipper teeth string integrally is fixed on the slide fastener selvedge by making static line, thereby even slide fastener selvedge is stressed, has improved the ability that slide fastener opposing pulling force is concentrated, and has avoided taking place at stressed concentrated position the situation that zipper teeth comes off or slide fastener such as slide fastener selvedge breakage damages.

The specific embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is described in further detail.

See also Fig. 5 earlier, diagram zipper teeth 10 is made by metal material, and its outer side is provided with perforation 110, and the both sides up and down of this perforation 110 have clamping end 11; Static line 20 penetrates the perforation 110 of all zipper teeth 10, each zipper teeth 10 equally spacedly arranged distribution on this static line 20, thereby clamping end 11 is clamped this static line 20 tightly all zipper teeth 10 is fixed on this static line 20, so just formed shown in Figure 6 about paired zipper teeth string.Consult Fig. 7 again, sewing line 41 is solid on slide fastener selvedge 40 with the static line on the zipper teeth string 20 seam, makes slide fastener 5 (see figure 8)s on the slide fastener selvedge 40 thereby zipper teeth string integrally is fixed on.When slide fastener 5 is subjected to the concentration of local pulling force, above-mentioned zipper teeth fixed structure just can make pulling force be uniformly dispersed and be distributed on the whole piece static line 20, thereby the stressed of slide fastener selvedge 40 also is evenly distributed, so just avoided the single adverse consequences that zipper teeth comes off or zipper cloth is pulled open that is fixed on stressed concentrating on the slide fastener selvedge and occurs of zipper teeth in traditional zipper.The surface of the zipper teeth 10 of slide fastener 5 can keep primary colors, also can carry out baking vanish or electroplate covering with paint.

Fig. 9 and Figure 10 have represented the structure of the utility model second embodiment.The zipper teeth 60 of slide fastener 6 is to be made by engineering plastics, this zipper teeth 60 is serially connected on the static line 61 equally spacedly, and be fixed on the static line 61 and form zipper teeth string with injection molding, integrally that the slide fastener slot is solid on slide fastener selvedge 62 in the mode of making static line 61 again, the slide fastener of making 6 as shown in figure 10.
