Abstract

The utility model discloses an upper and lower powerful structure that promotes of ending of zip fastener, the zip fastener the double strand chain tooth of chain belt upper end respectively injection moulding have left and right going up to end, the double strand chain tooth lower extreme injection moulding of chain belt have closed down only, the chain belt ends and seals down only position and be equipped with respectively and punch a hole corresponding left and right going up, left and right the going up of moulding plastics is ended and is sealed when ending down, punch a hole to seal on left and right and end and seal the inside of ending down. Upper and lower the ending of adopting this brute force to promote the structure is not changing under the prerequisite that has upper and lower only face shaping now, is showing to promote upper and lower brute force of ending to reach the technical requirement of trade.

Description

The powerful lift structure that slide fastener stops

Technical field

The utility model relates to a kind of zipper, refers in particular to slide fastener and to remain silent the modified node method of bottom stopper.

Background technology

What adopt is injection mo(u)lding for existing closed-end zipper upper and lower only general, as Chinese patent literature 03104753.X plastic cement, the once-forming automatic manufacturing method of nylon zipper bottom stopper disclosed in the 2004-09-01, the upper and lower brute force of stopping of this injection mo(u)lding generally can not reach industry technology requirement.Also have to adopt and withhold shaping mode, as Chinese patent literature 01260719.3 1 kinds of upper and lower stop structures of nylon zipper disclosed in the 2002-07-10, though this is withheld shaping upper and lower brute force of stopping and wants large compared with injection mo(u)lding, still have certain distance with the technical requirement of industry.Promote upper and lower brute force of stopping, be the difficult problem that dealer produced by puzzlement slide fastener always.

Utility model content

For the deficiencies in the prior art part, the powerful lift structure that the utility model provides slide fastener to stop.Adopt the upper and lower only under the prerequisite not changing existing upper and lower only face shaping of this powerful lift structure, significantly promote upper and lower brute force of stopping, to reach the technical requirement of industry.

For achieving the above object, the utility model adopts following technical scheme:

The powerful lift structure that slide fastener stops, described slide fastener the double strand chain tooth upper end of chain band respectively injection mo(u)lding have left and right on only, the double strand chain tooth lower end injection mo(u)lding of chain band has closed only lower; Chain band stops on correspondence is left and right and closed lower position is only respectively equipped with punching; Injection moulding left and right upper only and close lower only time, described punching is sealed in left and right only upper and close lower inside only.

The powerful lift structure that foregoing slide fastener stops, on the strap that described punching is arranged on chain band or cloth muscle.

The usefulness of technique scheme is:

The powerful lift structure that the utility model slide fastener stops on correspondence is left and right, stops and close lower position be only respectively equipped with punching, this punching is a through hole, injection moulding upper and lower only time melting material can by punching strengthen upper and lower only with the adhesion of chain band, and punching on left and right only and close be sealed in lower injection moulding process only left and right on only and close lower inside only, strengthen upper and lower brute force of stopping while not changing existing bottom stopper face shaping.The utility model adopts macroscopic punching, not only can locate better when injection mo(u)lding, can also avoid the bad product of injection mo(u)lding.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is that the utility model is remained silent the perspective view one (slide fastener drawing state, without upper and lower only) of upper and lower only powerful lift structure;

Fig. 2 is that the utility model is remained silent the perspective view (slide fastener open mode, have upper and lower only) of upper and lower only powerful lift structure.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Slide fastener as shown in Figure 1, 2, chain band 10 lines up double strand chain tooth 20 to form chain embryo through row microphone machine, according to order requirements, fixed for the chain embryo of whole section cun toothwash is become the segment chain embryo of equal length, and the intermediate chain band portion washing tooth off is called as the edge of a knife 30, on the edge of a knife 30 injection mo(u)lding on having only and lower side divide.Namely, the upper end of the double strand chain tooth 20 of a bit of chain embryo respectively injection mo(u)lding have left and right on only 40, corresponding, have closed lower only 50 in the lower end injection mo(u)lding of this double strand chain tooth 20.

The utility model increases red needle to toothwash mould (scheming not shown), in the operation to the fixed cun toothwash of chain embryo, utilize red needle at the upper-lower position upper punch lower through-hole of the edge of a knife 30 to form punching 60,70, simple to operate, under the prerequisite not changing original process, change mould solve upper and lower powerful problem of stopping.The utility model punching 60,70 is through hole, wherein, above only punching 60 corresponding left and right upper only 40 position arrange, lower only punching 70 close lower only 50 position arrange.

As shown in Figure 2, injection moulding upper and lower only 40,50 time, the material of melting can by punching 60,70 by upper and lower only 40,50 positive and negative more connect together, strengthen upper and lower only 40,50 and the adhesion of chain band 10.Described punching 60,70 on left and right only 40 and close lower only 50 injection moulding process in be sealed in left and right on only 40 and close lower only 50 inside, formed strengthen upper and lower only 40,50 the upper and lower only powerful lift structure of remaining silent of brute force.

The utility model chain band 10 comprises strap 11, and cloth band edge is knitted and added cloth muscle 12, and described punching 60,70 can be arranged on the cloth muscle 12 of chain band 10 as shown in Figure 1, also can be arranged on the strap 11 of chain band 10 as shown in Figure 2.

Above-mentioned explanation illustrate and describes preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
