Abstract

The utility model relates to a zipper head structure. The structure comprises an upper rib, a lower rib, a guide pillar, a cap and a stopping pillar, wherein the guide pillar is arranged between the upper and the lower ribs and fixedly connected therewith through integral forming; two bulged parts are formed on the upper surface of the upper rib; a groove is formed on the outer side surface of each bulged part; two bosses are correspondingly formed on the inner side of the bottom of the cap and respectively riveted with the grooves of the bulged parts on the upper surface of the upper rib; one end of the stopping pillar is fixedly arranged on the guide pillar, while the other end thereof is arranged on the upper rib in a suspending manner and extended towards part of the lower rib, so as to be clamped between two adjacent teeth for stopping; and the stopping pillar is produced through the folding of a spring steel wire.

Description

A kind of slider of zipper fastener

Technical field

The utility model relates to a kind of slide fastener, particularly a kind of pull header structure technology.

Background technology

Existing slide fastener be known, and it generally comprises chain tooth, pull head, pulling-on piece, goes up lower dead flake, nationality by pull head on the chain tooth, walk the realization slide fastener coupling element engagement with separate.With reference to figure 1 and Fig. 2, known pull head comprises upper panel 1 ', lower panel 2 ', guide pillar 3 ', block 4 ', stop bit reed 5 ' and back-moving spring 6 ', wherein said upper panel 1 ' and lower panel 2 ' are by the setting that links to each other of guide pillar 3 ' one, upper panel 1 ' upper surface has upwardly extending lug boss 11 ', described block 4 ' is covered on the described lug boss 11 ' outside, make block 4 ' and upper panel 1 ' be fastenedly connected by punching press in the 4 ' lateral of blocking a shot being formed depressed part 41 ', described stop bit reed 5 ' is located at that upper panel 1 ' is gone up and the one end extends to be used to snap in to lower panel 2 ' part movably and stops pull head to slide on the chain tooth between two adjacent chain teeth, be positioned between block 4 ' inboard and the stop bit reed 5 ' and be provided with back-moving spring 6 ', in the time of assembling, the hinged stop bit reed 5 ' opening portion of being located at of one side of pulling-on piece, like this when drawing on the pulling-on piece, the elastic force that stop bit reed 5 ' overcomes back-moving spring 6 ' upwards rotates, the far-end of stop bit reed 5 ' makes pull head to slide relatively from leaving between the chain tooth, otherwise when pulling-on piece no longer applies pulling force, reenter at the effect lower position-arresting reed 5 ' of back-moving spring 6 ' and to prevent between the chain tooth that pull head from sliding.Its weak point of the pull head of this kind structure is that stop bit reed 5 ' is laminated structure, and it is difficult for the location at horizontal direction, so it does not always enter start stop bit effect between the adjacent chain tooth very swimmingly; Carry out the punching press action when blocking a shot 4 ' location in addition and can produce distortion, this might cause back-moving spring 6 ' loss of elasticity.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, service-strong pull header structure.

The technical scheme that the utility model adopted is such: a kind of slider of zipper fastener structure, comprise upper panel, lower panel, guide pillar, block and stop bit post, described guide pillar is located between upper panel and the lower panel and the three in one moulding is fixedlyed connected, described upper panel upper surface is provided with two lug bosses, the lateral surface of every lug boss is provided with groove, described block bottom inside is corresponding be provided with groove that two protruding platforms are provided with two lug bosses with the upper panel upper surface respectively mutually riveted connect, described stop bit post one end is fixedly arranged on the guide pillar, the stop bit post other end be suspended on the upper panel and to lower panel local extend to be used to snap between the two adjacent chain teeth carry out stop bit, described stop bit post forms by spring steel wire is folding.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are to substitute known stop bit reed by the stop bit post that adopts spring steel wire to make, on the one hand, fixing reliably with guide pillar of stop bit post, stop bit post strain up and down can not take place crooked and can snap in start stop bit effect between two adjacent chain teeth exactly.

The specific embodiment

With reference to figure 3, Fig. 4, embodiment discloses a kind of slider of zipper fastener, comprise upper panel 1, lower panel 2, guide pillar 3, block 4, stop bit post 5, described guide pillar 3 is located between upper panel 1 and the lower panel 2 and the three in one moulding is fixedlyed connected and form two chain middlemen between upper panel 1 and lower panel 2 walks passage, described upper panel 1 upper surface is provided with two lug bosses, the lateral surface of every lug boss is provided with groove 21, described block 4 bottom inside are corresponding be provided with groove 21 that two protruding platforms 22 are provided with two lug bosses with upper panel 1 upper surface respectively mutually riveted connect, in traditional block 4 and upper panel 1 connected mode, all it is fixed to lug boss depression by punching press 4 lateral walls of blocking a shot, this kind connected mode causes the block distortion easily in assembling process, the back-moving spring of being located at like this in the block will lose reset response, in the present embodiment, described block 4 bottom inside are corresponding be provided with groove 21 that two protruding platforms 22 are provided with two lug bosses with upper panel 1 upper surface respectively mutually riveted connect, block 4 is subjected to the less and unlikely distortion of external force when assembling like this, stop bit post 5 one ends are fixedly arranged on the guide pillar 3, stop bit post 5 other ends be suspended on the upper panel 1 and to lower panel 2 local extend to be used to snap between the two adjacent chain teeth carry out stop bit, whole stop bit post 5 forms and roughly is down " U " shape by spring steel wire is folding, thereby when stop bit post 5 one ends were fastened on the guide pillar 3, the free end of stop bit post 5 can be brought into play the stop bit effect and unlikely generation is crooked.During actual the use, an end of pulling-on piece 6 is arranged between block 4 and the upper panel 1, and pulling-on piece 6 is crossed at stop bit post 5 middle parts, and when pulling-on piece 6 was stressed, stop bit post 5 free ends left from the chain tooth, pull head chain tooth slip relatively like this.
