Description

Apple shape chain tooth slide fastener

Technical field

The utility model relates to art of zipper fabrication, particularly relates to a kind of apple shape chain tooth slide fastener.

Background technology

Existing slide fastener adopts synthetic resin to make mostly, mostly mould its few of change in appearance of firm slide fastener, more and more can not adapt to the more diversified market demand, so need again changing in appearance of chain tooth, but have simultaneously need to ensure this slide fastener by force intensity.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of planform novel and be subject to the apple shape chain tooth slide fastener that force intensity is stronger.

For achieving the above object, described apple shape chain tooth slide fastener comprises first band with the first ora terminalis, second band with the second ora terminalis, is fixed on the chain tooth of the first ora terminalis and the second ora terminalis, and the described first chain tooth brought is interlaced with each other chimeric with the described second chain tooth brought;

Wherein, described chain tooth comprises the first cylinder and the second cylinder of being with plane perpendicular to described first, described first cylinder is fixed on described first ora terminalis or the second ora terminalis, described second cylinder is used for staggered chimeric, the upper surface of described first cylinder is apple shape, the upper surface of the second cylinder is oval, and described first cylinder is higher than described second cylinder.

Further, described first cylinder and described second cylinder one-body molded.

Further, described first cylinder is also provided with holddown groove, described holddown groove is fixed on described first ora terminalis or the second ora terminalis.

Further, be provided with junction surface between described first cylinder and described second cylinder, described junction surface is provided with an ellipse arc groove, and described groove is meshed with described second cylinder.

Its chain teeth structure of the utility model apple shape chain tooth slide fastener is novel; Its second cylinder area is comparatively large, increases the occlusal contact area of this chain tooth, stressed stronger; The difference in height of the first cylinder and the second cylinder prevents from when can use colliding damage second cylinder, affects slide fastener and uses.

Detailed description of the invention

For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

The utility model detailed description of the invention provides a kind of apple shape chain tooth slide fastener.

Refer to Fig. 1 to Fig. 5, described apple shape chain tooth slide fastener comprises the chain tooth 3 having first of the first ora terminalis 11 and be with 1, have second of the second ora terminalis 21 the band 2, be fixed on the first ora terminalis 11 and the second ora terminalis 21, and the chain tooth 3 and described second on described first band 1 is with the chain tooth 3 on 2 interlaced with each other chimeric.

Wherein, described first ora terminalis 11 and the second ora terminalis 21 are provided with the heart yearn for fixing chain tooth 3.

Refer to Fig. 6 to Fig. 8, wherein, described chain tooth 3 comprises the first cylinder 31 and the second cylinder 32 perpendicular to described first band 1 plane, described first cylinder 31 is fixed on described first ora terminalis 11 or the second ora terminalis 21, described second cylinder 32 is for staggered chimeric, the upper surface of described first cylinder 31 is apple shape, and the upper surface of the second cylinder 32 is oval, and described first cylinder 31 is higher than described second cylinder 32.

In the present embodiment, described first cylinder 31 and the second cylinder 32 adopt hard plastic material; When described second cylinder 32 is interlaced with each other be entrenched togather time, this slide fastener close.

Its outward appearance of slide fastener with said structure is more novel, can be used in have particular appearance require knitted fabric on; Second cylinder 32 area of this slide fastener increases relatively, can increase the stressed of this slide fastener; In addition, described first cylinder 31 can be protected described second cylinder 32 higher than described second cylinder 32, and prevent described second cylinder 32 from receiving collision damage, thus cause chain tooth 3 to lack, impact uses.

Further, described first cylinder 31 is one-body molded with described second cylinder 32.

Further, described first cylinder 31 is also provided with holddown groove 311, described holddown groove 311 is fixed on described first ora terminalis 11 or the second ora terminalis 21.

In the present embodiment, described holddown groove 311 is circular port, and this circular port is for being fixed on heart yearn.In other embodiments, the shape of described holddown groove 311 and size will be arranged according to the shape of chain band first ora terminalis 11 or the second ora terminalis 21 and size.

Further, be provided with junction surface 33 between described first cylinder 31 and described second cylinder 32, described junction surface 33 is provided with an ellipse arc groove 331, and described groove 331 is meshed with described second cylinder 32.

This junction surface 33 can increase the stressed of described second cylinder 32.

The above; for the person of ordinary skill of the art; can make other various corresponding change and distortion according to the technical solution of the utility model and technical conceive, and all these change and be out of shape the protection domain that all should belong to the utility model claim.
