In order to cooperate different use occasions, slider of zipper fastener is also had nothing in common with each other, and, must have and prevents from down or the downslide function with after the slider of zipper fastener drawing as open end zipper, even as closed-end zipper, women's dress back as described above also must tool prevents from down or the function of downslide.

Existing slider of zipper fastener, for preventing to glide after the drawing, usually extend a needle pin at the pulling-on piece back side,, and force the one needle pin to press down and sting to close spring head (Springlock) or automatic head (Autolo-ck) in non-driving status in the chain between cog by spring as aciculiform lock pin (Pinlock); Therefore, the hole confession needle pin that slider of zipper fastener bottom must the tool correspondence passes through.

This mode is a backstop with the prominent needle pin of a point all, and therefore, being provided with of slider of zipper fastener or pulling-on piece, its thickness is thicker, and element is more, and fit on is comparatively complicated, and cost is improved.

Recently, requirement is gone up in the women's dress design does not make slide fastener expose, and the someone uses CONCEAL ZIPPER, and aforementioned various slider of zipper fastener, owing to can't move top to during drawing, so the slide fastener chain belt must be reserved a segment distance, the neck both sides that are sutured in clothes respectively with clasp are fastened with the assurance driving fit again.The operation of this stitching clasp is very trifling in women's dress processing and operating personnel is fed up with; And the women is always inconvenient in the behind fastening when wearing the clothes.

The purpose of this utility model is to provide a kind of slider of zipper fastener, though it does not have needle pin, can prevent slippage effectively, and practicality is good.

The purpose of this utility model is achieved in that promptly provides a kind of slider of zipper fastener, and it comprises: one undercuts, and is plates, is rectangle substantially, and its rear end is that opening end inwardly tiltedly contracts, and width is less; A sheet, with undercut integrally formed and shape corresponding to undercuting but size is less, itself and undercut between link by the support sheet that assumes diamond in shape substantially, and make and form the sheet crack of size therebetween corresponding to sprocket thickness; Then splaying from two side direction central authorities in its two ends, and makes the counterpiece crack be oblique; One front wing, closing end both sides one is up extended from undercuting and it is current for chain belt to form road, a front wing crack therebetween through transferring, making for it; One rear wing, the opening end both sides one that undercuts is certainly up extended and is transferred, and makes that to form road, a rear wing crack therebetween current for chain belt.

The advantage of the utility model slide fastener is:

(1) element is simple, cuts down finished cost;

(2) thickness attenuation is suitable for to be installed on the women's dress, does not especially have the design of needle pin, can shouting pain skin;

(3) effectively prevent slippage, after use a period of time, the spring failure of general slide fastener or the awkward situation that the needle pin purifying can cause preventing slippage, this slide fastener can be avoided;

(4) chain interband adaptation is good, except that making sprocket do not expose, simultaneously, because of front wing 3 is oblique design, and it covers slider of zipper fastener, and pulling-on piece is in inner face, thus slider of zipper fastener do not expose, move the top to after, chain belt is voluntarily to central driving fit, when using rearward, can move the top to and clasp more not.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Schematic perspective view when Fig. 1 is used for common slide fastener for the utility model slider of zipper fastener;

Fig. 2 is the top view of slider of zipper fastener among Fig. 1;

Schematic perspective view when Fig. 3 is used for CONCEAL ZIPPER for the utility model slider of zipper fastener;

Fig. 4 is the top view of slider of zipper fastener among Fig. 3.

As shown in Figure 1, 2, what the utility model slider of zipper fastener comprised that a rectangle and one end inwardly splay undercuts 1, sheet 2 of its central tool, the front end that undercuts are to arch upward and transfer and form two front wings 3 in drawing direction both sides, and its opposite end is that the rear is extended and turned and forms rear wing 4.

Wherein, undercuting 1 is similar to known slider of zipper fastener bottom, and its purpose is to pass through from it for sprocket, and supports sprocket by this.Its back side then is provided with pulling-on piece, because of irrelevant with this slider of zipper fastener technical characterictic, so do not narrate.

The shape of seat sheet 2 is corresponding to undercuting 1, undersized, and parallel each other, its bottom center, the support sheet 21 (shown in Fig. 3 dotted line) of the approximate rhombus of tool one, seat sheet 2 outer rims and undercut 1, form a slice crack 22, its thickness is corresponding to sprocket thickness, and sprocket can be therebetween ccontaining.And the drawing direction end of seat sheet 2, i.e. front end is then contracted in inwardly oblique by both sides, and forms two oblique plate edge 23, and related its sheet crack, below 22 that makes also is oblique shape.

It up extends front wing 3 and transfers from 1 the drawing end both sides one of undercuting, and makes it and undercuts between 1, forms road, a front wing crack 31, its height is corresponding to sprocket thickness, itself and other lateral plate crack 22 width that forms, corresponding to monolateral sprocket width, chain belt can be therebetween ccontaining and be made the slider of zipper fastener can smooth and easy sliding.

Rear wing 4 also extends and revolution from the 1 both sides one that undercuts, its end place and undercut 1 and form road, a rear wing crack 41, highly also corresponding to sprocket thickness, with sheet crack 22 width that forms of respective side corresponding to monolateral sprocket width, sprocket can be therebetween ccontaining.

During operation, after embedding penetrates in the road, front wing crack 31 respectively with two chain belts on the chain belt, then can spur slider of zipper fastener, i.e. 41 back engagements of sprocket, and as shown in the figure in road, rear wing crack, its chain belt and forms driving fit in central authorities up.

For preventing to unclamp or slider of zipper fastener drops, the utility model front wing 3 oblique central authorities, so make not the chain belt of engagement also be oblique central mobile, even when two chain belts are subjected to opening external force, the direction of its force direction during also with the normal drawing of slide fastener is vertical, and because of sprocket independently is in discontinuous state separately, sprocket in inside edge is stressed, and can't influence adjacent each tooth, therefore, can't continue to pull open, slider of zipper fastener is with respect to sprocket that block can't interactive state.
