Description
Technical field
The utility model relates to a kind of small stores, especially a kind of slide fastener.
Background technology
Existing slide fastener coupling element is little, and snap-in force is poor, usually splits after closing, and use inconvenience, and the chain tooth is too little, often falls down from strap, influences people's normal use.When being used for large piece article such as automobile outer cover, large-scale transportation band and some special occasions, above-mentioned shortcoming is particularly evident.
Summary of the invention
The purpose of this utility model provides a kind of in conjunction with firm, and is easy to use, do not fall the novel slide fastener of chain tooth, and it has overcome the above-mentioned shortcoming that prior art exists.
The purpose of this utility model is achieved in that it includes chain tooth, pull head and strap, described chain tooth head has groove, is provided with Ka Tai in the deep-slotted chip breaker of chain tooth two middle side parts, and chain tooth afterbody has binding groove, chain tooth tail end is provided with fastening card, has aperture on the described fastening card.
The bottom land of described binding groove is an arc.
Described aperture is two.
Because the utility model has adopted said structure, compared with prior art has the following advantages: use is flexible, combination is firm; Chain tooth afterbody has installed fastening card additional, and it is more firm that the chain tooth is combined with strap, can not fall the chain tooth; Can be used for fashion knapsack and big article such as automobile outer cover, large-scale transportation band and some special occasions; Very big because of using present technique to make slide fastener, novel structure uniqueness not only, and have very strong decorative effect and demonstration effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a chain tooth schematic diagram of the present utility model;
Fig. 3 is a chain tooth side view of the present utility model.
Among the figure: 1. chain tooth; 2. Ka Tai; 3. strap; 4. aperture; 5. fastening card; 6. pull head; 7. groove; 8. binding groove.
The specific embodiment
The slide fastener of this structure includes chain tooth 1, pull head 6 and strap 3, and the 1 integral molded plastic moulding of chain tooth has groove 7 at the head of chain tooth 1, is provided with card platform 2 in the deep-slotted chip breaker of 1 liang of middle side part of chain tooth, and chain tooth 1 tail end is provided with fastening card 5, has aperture 4 on the fastening card 5.Be provided with binding groove 8 at chain tooth 1 afterbody in addition, the bottom land of binding groove 8 is an arc.During use strap 3 is prevented that in the binding groove 8, there is projection at the edge of strap 3, just in time put into the arc of binding groove 8 bottom lands, because of the width of the radius ratio binding groove 8 of the arc of binding groove 8 bottom lands is big, so can hold the projection at strap 3 edges.Thermoplastic is stuck on the strap 3 chain tooth 1 then.Because of the slide fastener of this structure can do very big, so set up fastening card 5 at chain tooth 1 tail end, have aperture 4 on the fastening card 5, the number of aperture 4 can be as required and the size decision of chain tooth 1, and the effect of fastening card 5 is to make chain tooth 1 clamp strap 3 more firmly, and two apertures 4 offering on it are when chain tooth 1 thermoplastic is on strap 3, the fiber of strap 3 is entered in the aperture 4, the combination of further firm chain tooth 1 and strap 3 is though so chain tooth 1 is big, in conjunction with firmly.After pull head 6 was pulled through, chain tooth 1 was engaged, in order to make the tightr of chain tooth 1 interlock, had groove 7 at the head of chain tooth 1, was provided with card platform 2 in the deep-slotted chip breaker of 1 liang of middle side part of chain tooth.Like this when chain tooth 1 is engaged, the groove 7 of one side strap, 3 cochain teeth, 1 head blocks the card platform 2 at opposite side strap 3 cochain teeth 1 middle part, make the not only protruding tooth of chain tooth 1 of both sides engaged, and groove 7 blocks card platform 2, the further firm combination of slide fastener can not ftractureed it.The utility model is a kind of injection molding zipper, can do very big during manufacturing, novel structure not only, and can on chain tooth 1 and pull head 6, draw and write literal or pattern, have very strong decorative effect and demonstration effect,, make slide fastener very firm again because of its particular structure, so can not occur splitting and falling the chain dental phenomenon in using, can be used for fashion knapsack and big article such as automobile outer cover, large-scale transportation band and some special occasions.
