Description

The slider of zipper fastener pulling-on piece mechanism of unidirectional lock

The utility model is the slider of zipper fastener pulling-on piece mechanism about a kind of unidirectional lock, is meant that especially a kind of energy forms the structure that is easy to locate pulling-on piece.

Known slide fastener has been used many decades, be to be used on the various clothes such as clothing, with the convenient zipper that can easily open or closely close by dilatory action, as shown in Figure 8, include a headstock 10, one pulling-on piece 11 and a shell fragment 12, with dashed lines shows that both sides penetrate the chain belt 5 of the tool begin chain in the headstock 10, having a Y shape groove 15 in slider of zipper fastener 1 its headstock 10 can wear wherein from two sides for corresponding two chain belts, these headstock 10 end faces are provided with two pairs of pivot ears 14 can wear pivot wherein for the round bull stick 16 of a pulling-on piece 11, and be subjected to a shell fragment 12 that front and back vertically are provided with across and can freely rotate with respect to headstock 10, if desire is formed complete slide fastener, one chain belt in two chain belts must be arranged in earlier in the side channel road of Y shape groove 15, in other words, promptly need earlier this slider of zipper fastener 1 to be pre-assembled on the chain belt, can be about to another chain belt in use certainly for the user is arranged in the in addition side channel road of Y shape groove 15, because though pulling-on piece 11 is subjected to shell fragment 12 compressing restrictions, but its circle bull stick 16 still can freely rotate with respect to headstock 10 fully and can't locate, so when gripping pulling-on piece 11 fixedly the time, headstock 10 but can constantly shake wantonly the pendulum indefinite, and be difficult for wearing smoothly for chain belt, so on assembling line, must rely on the manpower manual mode just to be enough to suitably overcome this problem fully, thus, too consuming time the taking a lot of work of assembling procedure for producing that will cause whole slide fastener again, not only production efficiency is low, and production cost and fraction defective are all too high, cause lacking the market competitiveness, so someone makes the structure of Fig. 8 into the structure of Fig. 7, on the round bull stick 16 of pulling-on piece, be provided with a projection 16a, and this projection 16a is the square shape, owing to be to utilize pulling-on piece to spur this slider of zipper fastener in order to control the closed of slide fastener or to separate, this shell fragment 12 is one of to be positioned on this slider of zipper fastener headstock 10 fixedly ear 18 places with fixed part 13, this shell fragment 12 is to have a blocking part 18, this blocking part 18 can run through this one hole 19, slider of zipper fastener top and stretch in this slider of zipper fastener body interior, so that clip on slide fastener, make this pulling-on piece not when pulled slider of zipper fastener can be a clip stationary state.But, because the intensity of this shell fragment is limited, even slider of zipper fastener is under the clip stationary state, still might be because of the external force effect produce unexpected moving, the intensity of its opposing pulling force is relatively poor, makes this pulling-on piece be subject to the shape guiding of square shape projection again, rotation has some setbacks, and can produce the state that blocks.

The purpose of this utility model is to provide a kind of slider of zipper fastener pulling-on piece mechanism of unidirectional lock, improve the pivot joint state of the bonding station between pulling-on piece and shell fragment, the strength of the limit axle rotation of shell fragment opposing pulling-on piece is reduced, flexible pressure is reduced, so that the execution of pulling-on piece rotational action, use location, preferable location in the middle of obtaining, the elastic fatigue degree of shell fragment is reduced, friction reduces, the comfort that more allows the user obtain using, and behind the location clear and definite response sound is arranged, directly allow the user experience, also improve the easness and the convenience of assembling relatively.

For achieving the above object, the utility model is taked following design: the slider of zipper fastener pulling-on piece mechanism of this unidirectional lock has a slider of zipper fastener, one pulling-on piece and a shell fragment, this slider of zipper fastener is provided with the body of a hollow, the guiding inlet that body one side forms snapping forms the guiding outlet that separates shape with another side, be provided with a perforation in the body outer face, shell fragment has the portion of closing of colluding, jut, pressing portion, be connected on this perforation place with colluding the portion of closing, on the other body end face of perforation, be provided with two pairs of upright sheets that hold, one through hole is arranged on pulling-on piece, the axle place, limit of through hole is scratched be connected on corresponding a pair of holding in the pivot hole that a sheet forms, and the jut that makes shell fragment strides across the limit axle of pulling-on piece, on the body end face of perforation end opposite, be provided with a pair of compressing tablet, fix the pressing portion of shell fragment with compressing tablet, under guiding inlet state, be provided with a jut towards body in the outer end of pulling-on piece, make this jut form an inclined plane to place, pulling-on piece outer end at this limit axle.

In the utility model, this jut also forms teat outside to reverse place, the outer end of pulling-on piece.

The utility model is described in further detail below in conjunction with accompanying drawing.
