Description

A kind of structure improved slider of zipper fastener

The utility model relates to a kind of structural improvement of slider of zipper fastener.

Fig. 1 generally uses on various clothes, clothing, various cloth, the slider of zipper fastener 1 that can conveniently draw, open or closely close, it comprises a headstock 10, a pulling-on piece 11 and a shell fragment 12, having a Y shape groove 100 in the headstock 10 wears wherein from two sides for corresponding two chain belts, headstock 10 end faces are provided with two pairs of pivot ears 101 and wear pivot wherein for the round bull stick 110 of pulling-on piece 11, pulling-on piece 11 be subjected to a shell fragment 12 that front and back vertically are provided with across and can freely rotate relative to headstock 10, shown in second figure.

Yet when the assembling slide fastener, the one chain belt in two chain belts must wear earlier in the side channel road that is placed on Y shape groove 100, in other words, promptly need earlier this slider of zipper fastener 1 to be pre-assembled on the chain belt,, another chain belt can be worn in the side channel road in addition that is positioned over Y shape groove 100 so that the user in use.But, because this traditional slider of zipper fastener 1, though pulling-on piece 11 is limited by the compressing of shell fragment 12, but its circle bull stick 110 still can freely rotate and can't locate relative to putting headstock 10, only gripping pulling-on piece 11 is fixed, but constantly the rolling pendulum is indefinite wantonly for headstock 10, be difficult for being arranged in chain belt in the headstock smoothly, so on assembling line, must rely on the manpower manual mode just to be enough to suitably overcome this problem fully, to cause the assembling procedure for producing of whole slide fastener consuming time thus again, take a lot of work, not only production efficiency is low, and production cost and disqualification rate are all too high, lacks the market competitiveness.

The purpose of this utility model provides a kind of structure improved slider of zipper fastener, the assembling process that makes slider of zipper fastener and chain belt is promoted to the mechanical automation operation of greater efficiency by the inefficient handwork of tradition, thereby reduce production costs, enhance productivity, improve output and quicken sales volume, improve the market competitiveness.

For achieving the above object, the utility model adopts following design: a kind of structure improved slider of zipper fastener, and it comprises: a headstock, this headstock have relative up and down end face with the bottom surface and be connected the interval body that moulding is positioned at headstock front end central authorities; Be formed with Y shape groove between described end face and bottom surface; Described end face is provided with paired pivot ear; One pulling-on piece, this pulling-on piece is worn pivot in described headstock end face pivot ear by a bull stick; Described pulling-on piece can rotate relative to described headstock; Described bull stick inboard forms a card protuberance towards the pulling-on piece bearing of trend; One shell fragment, this shell fragment and described bull stick are positioned at across bull stick on the described headstock end face perpendicularly; Described shell fragment and the bull stick contact position that rotates is provided with a locating slot;

The bull stick leading flank of described pulling-on piece is a flat part, and rear side is a bent protuberance and extends to form the card protuberance along its curve to the bull stick inboard;

The front end of described headstock end face and rear end respectively are provided with one and wear a groove and a perforation, and preceding groove two sides of wearing have relative spacer, are subjected to this two spacers compacting location after wearing groove before described shell fragment front end inserts, and described shell fragment rear end is stretched in the perforation of back.

Because the utility model adopts above design, its pulling-on piece bull stick inboard that is hubbed on the headstock convexes with the card protuberance, and be provided with locating slot across the shell fragment corresponding position of this bull stick, when making pulling-on piece turn to headstock in vertical state, can be by the engaging of card protuberance and locating slot, obtain temporary transient location and make headstock arbitrarily rolling put, so can give clamping and fast, accurately and successfully chain belt is arranged in the slider of zipper fastener with automated machine, improve packaging efficiency, reduce cost.

Further specify below in conjunction with accompanying drawing.

As shown in Figure 3, Figure 4, the utility model slider of zipper fastener includes a headstock 2, a pulling-on piece 3 and a shell fragment 4, wherein headstock 2 has parallel up and down relative an end face 20 and a bottom surface 21, the front end central authorities connection of headstock 2 forms an interval body 22 and makes this top, 20,21 of bottom surfaces form a Y shape groove 23, corresponding two chain belts can wear respectively in the two side channel roads that are placed on this Y shape groove 23 on the clothing for being sewn to, and combine with headstock 2.Wear groove 200 and back perforation 201 before end face 20 front and back ends respectively are provided with, preceding groove 200 2 sides of wearing are provided with a pair of spacer 202, and end face 20 2 sides respectively are provided with a pair of pivot ear 203 in addition.

The bull stick 30 of pulling-on piece 3 by an end wears and is positioned in the aforementioned pivot ear 203, and pivot ear 203 is given the punching press condensation, and pulling-on piece 3 can be rotated relative to headstock 2.The front side of this bull stick 30 is shaped to flat part 300, and rear side is then protruding high to form inwards protruding high bent protuberance 301 (shown in Fig. 3-A), and the protruding high bent protuberance of rear side is taken advantage of a situation and formed a card protuberance 302 to the inside.

Wear in the groove 200 before shell fragment 4 front ends 41 insertion headstocks 2 front ends are default, two spacers 202 are given the punching press condensation, make shell fragment 4 compacting location.Connecing in the perforation 201 of headstock 2 rear ends stretched in the rear end 42 of shell fragment 4, make the protruding high press section 43 of shell fragment 4 and bull stick 30 perpendicularly across and suppress bull stick 3.Shell fragment 4 rotates the contact position with bull stick 30 and is arranged with a locating slot 40.

Fig. 4 is the overall structure figure after the slider of zipper fastener of said structure makes up.When the user pinches when getting pulling-on piece 3 and spurring this slider of zipper fastener forward, as shown in Figure 5, the bent protuberance 301 of its bull stick 30 is pushing tow shell fragment 4, and simultaneously, bull stick 30 is owing to the elastic force compressing that continues to bear shell fragment 4 keeps the location, user's facility application of force.When pulling-on piece 3 is turned over when pushing back, as shown in Figure 6, bull stick 30 will be by bent protuberance 301 then is become with flat part 300 relatively with shell fragment 4, and shell fragment 4 will play bullet rapidly and bull stick 30 is forced into flatly backwards stretch shape and locate.

It should be noted that when pulling-on piece 3 rotates to headstock 2 to be when standing vertically state that as shown in Figure 7, the card protuberance 302 of its bull stick 30 will be taken advantage of a situation in the locating slot 40 that snaps in shell fragment 4, make 2 of pulling-on piece 3 and headstocks can temporarily keep stable plumbness.So on production line, when this slider of zipper fastener is desired and chain belt wears when combining, can adopt automated machine equipment, grip vertical pulling-on piece 3 with anchor clamps on the one hand, on the other hand since this moment headstock 2 can keep stable level and not arbitrarily the swing, so can make chain belt fast, accurately, successfully wear is placed in the Y shape groove 23, thereby make slider of zipper fastener and chain interband finish combination with higher operating efficiency and lower production cost, significantly improve advantage quality, output and the market adaptability to changes of slide fastener product, and have higher production economic worth.
