Abstract
The utility model discloses a zipper provided with a firm pin box square block, which comprises the pin box square block (1) and a chain cloth belt (2), wherein the pin box square block (1) is divided into a box pin (3) and an inserting pin (4) which are provided with mounting holes (5) that are formed by upper surfaces (51) and lower surfaces (52); mounting openings (53) are formed at one ends of the joint parts between the upper surfaces (51) and the lower surfaces (52); the chain cloth belt (2) is fixed in the mounting holes (5) by stamping the mounting openings (53); and the upper surfaces (51) and/or the lower surfaces (52) of the mounting holes (5) of the box pin (3) and the inserting pin (4) are provided with convex parts (6) which extends upwards along the zipping direction of the zipper. The utility model enhances the fixing effect between the box pin (3) as well as the inserting pin (4) and the chain cloth belt (2) so as to ensure the box pin (3) and the inserting pin (4) not to easily fall off from the chain cloth belt (2), thus reducing the damage for the zipper.
Description
Technical field
The utility model relates to a kind of slide fastener, and particularly a kind of slide fastener with firm pin box block belongs to the technical field of zipper fabrication.
Background technology
Slide fastener in the market comprises that chain strap, sprocket, front and back end and pin box block and slider of zipper fastener.Wherein pin box block is divided into the box pin and inserts pin, box pin and insertion are provided with installing hole above selling, installing hole is made of upper surface, lower surface respectively, end in upper surface, lower surface junction is formed with installing port, be placed on the box pin after the terminal rubberizing of chain strap, insert in the installing hole of pin, be fixed in the installing hole by punching press then, box pin and insertion pin are fixed on above the chain strap installing port.
Fixedly processing mode like this is simple, but box pin and insertion pin are easy to come off above the chain strap, pull dynamics that chain strap and pull head unzip when excessive as external force, box pin, insertion pin very easily come off, cause the damage of slide fastener, to using the article of slide fastener, for example clothing has increased no small trouble.
The utility model content
Technical problem to be solved in the utility model provide a kind of can be with the pin box block slide fastener of punching press on the chain strap securely, to reduce the come off problem of chain strap of pin box block.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of slide fastener with firm pin box block, comprise pin box block and chain strap, pin box block is divided into the box pin and inserts pin, the box pin, insert pin and be provided with installing hole, installing hole is respectively by upper surface, lower surface constitutes, at upper surface, one end of lower surface junction is formed with installing port, the chain strap is fixed in the installing hole by the punching press to installing port, at described box pin, the upper surface and/or the lower surface that insert the installing hole of pin are provided with protuberance, and described protuberance is along extending on the drawing direction of slide fastener.
At punching press box pin, when inserting pin, installing port is fixedly the chain strap time, as if being provided with protuberance at upper surface, then protuberance and lower surface can be further fixing chain strap; If be provided with protuberance at lower surface, then protuberance and upper surface can be further fixing chain strap; If be respectively arranged with protuberance at upper surface, lower surface, then upper and lower protuberance can be further fixing chain strap.
In order to strengthen the fixed effect of protuberance, described protuberance is dentation.
On the drawing direction of slide fastener, protuberance can be set to linear pattern, and when reaching the effect of strengthening fixing, described protuberance can be provided with and be wavy, reduces the use of material, has saved resource.
Slide fastener with firm pin box block of the present utility model, at box pin, the inner protuberance that is provided with of insertion pin, can strengthen the box pin, insert the fixed effect between pin and the chain strap, make box pin, insertion pin be difficult for coming off, reduce the damage of slide fastener from the chain strap.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of slide fastener;
Fig. 2 is the sectional view of the insertion pin of slide fastener;
Fig. 3 be slide fastener box pin sectional view.
The specific embodiment
As shown in Figure 1, a kind of slide fastener with firm pin box block comprises pin box block 1 and chain strap 2, and pin box block 1 is divided into box pin 3 and inserts pin 4.
In order to strengthen the fixed effect of protuberance 6, described protuberance 6 can be arranged to dentation.
On the drawing direction of slide fastener, protuberance 6 can be set to linear pattern, and when reaching the effect of strengthening fixing, described protuberance 6 can be provided with and be wavy, reduces the use of material.
At punching press box pin 3, inserted pin at 4 o'clock, installing port 53 is fixedly chain strap 2 time, if be provided with protuberance 6 at upper surface, then protuberance 6 and lower surface 52 can be further fixing chain strap 2.
If be provided with protuberance 6 at lower surface, then protuberance 6 and upper surface 51 can be further fixing chain strap 2.
If be respectively arranged with protuberance 6 at upper surface 51, lower surface 52, then upper and lower protuberance 6 can be further fixing chain strap 2, make box pin 3, insert pin 4 and be difficult for coming off from chain strap 2, reduce the damage of slide fastener.
Above-mentioned at box pin 3, insert be provided with in the installing hole 5 of pin 4 that technical scheme that protuberance 6 strengthens fixed effects is fit to be applied in sprocket equally, precedingly ends, end the back with chain strap 2 fixing on.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
