Abstract

The invention provides a strong interdigitation zipper structure and a manufacturing method thereof. The strong meshing zipper structure comprises two woven belts, multiple hook teeth and multiple rubber teeth, wherein the multiple hook teeth are fixedly arranged in the edges of the woven belts; the multiple rubber teeth are formed on the hook teeth and connected with the edges of the woven belts in an occlusion manner; and the rubber teeth on the woven belts are in mutual and staggered occlusion. As one hook tooth in each rubber tooth is firstly in occlusion with the woven belts, and then the rubber teeth are formed on the woven belts through injection molding to cover the hook teeth to form the zipper teeth, the strength and the tolerance level of the zipper teeth are greatly increased.

Description

Strong meshing zipper and manufacture method thereof

Technical field

The present invention relates to a kind of zipper, particularly a kind of strong meshing zipper and manufacture method thereof increasing slide fastener intensity.

Background technology

Slide fastener is generally divided into nylon zipper and two kinds, ejection formation slide fastener, nylon zipper is wrapped on a center line by a nylon yarn to form sprocket, sprocket is fixed on strap and is formed by recycling suture, ejection formation slide fastener is then penetrated from mould by many sprockets, direct occlusion takes shape in cloth belt edge, forms ejection formation slide fastener.

Figure 1 shows that the schematic diagram of existing ejection formation slide fastener, two straps 10 there is multiple sprocket 12 respectively, each sprocket 12 is all snapped at the edge of strap 10, and the sprocket 12 of two straps 10 is misplaced alternately, the head 122 of sprocket 12 can be engaged mutually, utilize slider of zipper fastener 14 reach sprocket 12 engaged and be separated, but strap 10 is very thin plane, depend merely on ejection formation sprocket 12 and probably cannot tightly bite strap 10, and sprocket 12 is got loose, for example, if clothing uses ejection formation slide fastener and often to be pulled on by slide fastener from incorrect force direction and leaves behind, or clothing is too tight, firmly two straps must be drawn close and just can zip up, the lower sprocket then pullled for a long time just likely can get loose, whole piece slide fastener is needed to renew.

Therefore, namely the present invention proposes a kind of strong meshing zipper and manufacture method thereof, and to overcome these problems above-mentioned, concrete framework and embodiment thereof will be specified in down:

Summary of the invention

Main purpose of the present invention, providing a kind of strong meshing zipper, ticks tooth, outer injection glue tooth mode forms many sprockets and is snapped on strap within it, strengthen the meshing intensity of sprocket and strap.

Detailed description of the invention

The invention provides a kind of strong meshing zipper and manufacture method thereof, Fig. 2 A is perspective view of an embodiment of the present invention, strong meshing zipper and manufacture method thereof comprise two straps 20, multiple hook tooth 24, multiple glue tooth 26 and a slider of zipper fastener 30, hooking tooth 24 is metal material, strap 20 is bitten at the edge being located at strap 20, glue tooth 26 is that ejection formation, on hook tooth 24, will hook tooth 24 coated from mould, and glue tooth 26 also bites strap 20 simultaneously; One glue tooth 26 and a hook tooth 24 form a sprocket 28, the head 262 of left and right two row chain teeth 28 is crisscross arranged, the head 262 of left bank sprocket 28 just can be snapped in mutually with the head 262 of right row chain tooth 28, utilize slider of zipper fastener 30 that the head 262 of sprocket 28 can be made to snap in or separately, to reach the object pulled on by slide fastener or leave behind.

And in order to allow hook tooth 24 be engaged tightr on strap 20 with glue tooth 26, more a lines of occlusion 22 can be set at the edge of strap 20, itself and strap 20 are formed in one, but the width of lines of occlusion 22 is large compared with the width of strap 20, and hook tooth 24 and just bite this lines of occlusion 22 and fix, afterwards again by glue tooth 26 ejection formation on hook tooth 24, hook tooth 24 and slightly may adjust because of the thickness of lines of occlusion 22 with the shape of glue tooth 26.

Fig. 2 B is the enlarged schematic partial view of Fig. 2 A, can know and find out lines of occlusion 22 comparatively strap 20 is thick, and hook tooth 24 and catch on lines of occlusion 22 from the front of strap 20 and the back side, therefore in any direction exert a force and be all difficult to hook tooth 24 to be shut down, and when hooking tooth 24 and being firmly engaged, again by glue tooth 26 ejection formation on hook tooth 24, make 24, hook tooth inner at glue tooth 26, thus glue tooth 26 and hook the sprocket 28 that tooth 24 formed and will be difficult to by external force is shaken.

Fig. 3 is the top view of one embodiment of the invention, by finding out in figure that hook tooth 24 catches on the edge that lines of occlusion 22 is fixed on strap 20 in glue tooth 26, lines of occlusion 22 is not essential, if do not have lines of occlusion 22, the sprocket 28 that hook tooth 24 and glue tooth 26 are formed will directly be snapped at the edge of strap 20; The interlaced engaging of head 262 of the sprocket 28 of left and right two row.

Fig. 4 is the flow chart of the manufacture method of the strong meshing zipper of the present invention, first in step slo multiple hook tooth is first stamped at the edge of at least two straps, each distance hooking space of teeth is identical, and hook tooth is U-shaped, and the edge of strap is bitten on both sides respectively from the front of strap and the back side; Step S12 becomes this glue tooth of multiple glue tooth to be that general glue tooth mould ejection formation is hooking on tooth in hook tooth outline, and coated hook tooth forms multiple sprocket, and is snapped at the edge of strap, forms a row chain tooth; The sprocket of two straps is faced toward sprocket by final step S14, and two row chain teeth interlock, and put a slider of zipper fastener and namely form strong meshing zipper of the present invention.

In sum, strong meshing zipper provided by the present invention and manufacture method thereof squeeze into a hook tooth in each glue tooth inside, outside with normal glue tooth mould ejection formation glue tooth, utilize and hook tooth and be engaged with tight between strap, glue tooth is also closely engaged with strap, and glue tooth also can protect the hook tooth of metal material to get rusty; In addition, to strengthen the tight ness rating hooking tooth and strap again, a lines of occlusion can be become in the overstriking of cloth belt edge, hook tooth to bite from upper and lower leap lines of occlusion, make the meshing intensity between sprocket and strap better, sprocket pole not easily departs from strap, no matter be applied in the places such as clothing, knapsack or luggage case, all can make it have better tolerance and slide fastener can not be made to collapse out.

Only the above, be only preferred embodiment of the present invention, is not used for limiting scope of the invention process.Therefore namely all equalizations of doing according to the feature described in the present patent application scope and spirit change or modify, and all should be included in claim of the present invention.
