Abstract
A kind of structure improved drawing chain tooth, comprise metal tooth body, one end of described metal tooth body is provided with the tight lock part be snapped on strap, the other end of described metal tooth body be provided with one for reducing slide fastener reverse drawing time meshing resistance groove of stepping down.The utility model structure is simple, practical, by groove of stepping down described in arranging, can be avoided by superfluous friction point on chain tooth engagement progress curve, thus meshing resistance when reducing slide fastener reverse drawing, make slide fastener drawing smooth and easy, non-resistance, be conducive to lifting and draw sense.The utility model structure is simple, practical, by groove of stepping down described in arranging, can be avoided by superfluous friction point on chain tooth engagement progress curve, thus meshing resistance when reducing slide fastener reverse drawing, make slide fastener drawing smooth and easy, non-resistance, be conducive to lifting and draw sense.
Description
Technical field
The utility model relates to slide fastener field, refers in particular to a kind of structure improved drawing chain tooth.
Background technology
At present, Y wire rod method has become the most frequently used manufacture method of manufacture metal tooth, when Y wire rod legal system makes metal tooth, supply the wire rod of circular section off and on predetermined space for the manufacture of the metal wire rod of the circular section of chain tooth, produce the basic wire rod for Y shape section with the multistage rolling of multiple roll again, then the metal wire rod of Y shape section is cut into multiple chain tooth by predetermined thickness.The chain tooth of a cutting comprises a tooth head and a pair tooth pin, and two tooth pin are symmetrical and extend to form tooth head at interface point place, and two tooth pin and tooth head are Y shape, and a pair tooth pin formed opens.After chain tooth bud part presses installing space feeding strap, the marginal portion of strap is made to face between chain tooth bud part two tooth pin, now squeeze two in tooth die holder and squeeze cutter action in opposite directions, inwardly being extruded by two tooth pin makes tooth pin inwardly merge convergence, chain dental inlay is closed and is fixed on strap, is fixed on strap by chain tooth thus by pitch.
Chinese invention patent (the application number: 03110558.0 that YKK Co., Ltd of Japan applies at it, patent name: the metal wire rod making slide fastener coupling element and the slide fastener coupling element made thereof) disclose a kind of slide fastener coupling element structure, with an improved the stability of position of the metal tooth obtained by cutting Y wire rod, the intensity of chain tooth and chain tooth to the stability of the installation site of zipper strip.But the above slide fastener coupling element back side is plane, can friction be produced at drawing process medium chain tooth curve and plane, cause drawing to have some setbacks or drawing difficulty comparatively large, the lifting of limit product quality to a certain extent.
Utility model content
The utility model provides a kind of structure improved drawing chain tooth, and its main purpose is to overcome the defect that the friction that existing slide fastener coupling element exists in drawing process is comparatively large, drawing has some setbacks.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of structure improved drawing chain tooth, comprise metal tooth body, one end of described metal tooth body is provided with the tight lock part be snapped on strap, the other end of described metal tooth body be provided with one for reducing slide fastener reverse drawing time meshing resistance groove of stepping down.
Further, described metal tooth body is provided with a breach in the side of described groove of stepping down.
Further, described metal tooth body comprises the holding section that one end is incorporated into the tight lock part on strap and is connected to described tight lock part, described tight lock part comprises two clamps, described holding section entirety is arranged in a cone shape ground, and it includes a conical lower portion and by the slot of the downward hollow out of end face.
Further, the side-wall outer side of described holding section be provided with described in step down groove.
Further, described breach is positioned at outside the end face of described holding section.
Further, described breach communicates with described groove of stepping down.
Further, described breach is arc notch, semicircular indentations or polygon breach.
Further, groove of stepping down described in is deep-slotted chip breaker.
Further, the section of described deep-slotted chip breaker is that minor arc shape is arranged.
Compared to the prior art, the beneficial effect that the utility model produces is:
1, the utility model structure is simple, practical, by groove of stepping down described in arranging, can be avoided by superfluous friction point on chain tooth engagement progress curve, thus meshing resistance when reducing slide fastener reverse drawing, make slide fastener drawing smooth and easy, non-resistance, be conducive to lifting and draw sense.
2, in the utility model, by arranging described breach, the effect of groove that cooperation is stepped down, one side convenient formation in process of production, can reduce accessory loss; Reverse drawing can be made consistent with the smooth degree of forward drawing on the other hand, thus effectively improve service life and the Consumer's Experience of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Fig. 1 in A view.
Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2.A kind of structure improved drawing chain tooth, comprise metal tooth body 1, one end of described metal tooth body 1 is provided with the tight lock part 10 be snapped on strap, the other end of described metal tooth body 1 be provided with one for reducing slide fastener reverse drawing time meshing resistance groove 11 of stepping down.Superfluous friction point, by groove 11 of stepping down described in arranging, can be avoided by the utility model on chain tooth engagement progress curve, thus meshing resistance when reducing slide fastener reverse drawing, make slide fastener drawing smooth and easy, non-resistance, be conducive to lifting and draw sense.
See figures.1.and.2.Described metal tooth body 1 is provided with a breach 12 in described side of stepping down groove 11.Described metal tooth body 1 comprises the holding section 13 that one end is incorporated into the tight lock part 10 on strap and is connected to described tight lock part 10, described tight lock part 10 comprises two clamps 101, described holding section 13 entirety is arranged in a cone shape ground, and it includes a conical lower portion 130 and by the slot 131 of the downward hollow out of end face.To step down described in the side-wall outer side of described holding section 13 is provided with groove 11.Described breach 12 is positioned at outside the end face of described holding section 13.Described breach 12 communicates with described groove 11 of stepping down.In the present embodiment, described breach 12 is arc notch, semicircular indentations or polygon breach.In the present embodiment, described in groove 11 of stepping down be preferably as deep-slotted chip breaker, and the section of this deep-slotted chip breaker is preferably and arranges in minor arc shape.By arranging described breach 12, the effect of groove 11 that cooperation is stepped down, one side convenient formation in process of production, can reduce accessory loss; Reverse drawing can be made consistent with the smooth degree of forward drawing on the other hand, thus effectively improve service life and the Consumer's Experience of product.
