Abstract
Explosion -proof zip fastener includes strap, zip fastener tooth and expanding element, the spiral strip body of zip fastener tooth for forming by a plurality of spiral unit integrated into one piece, zip fastener slit between the teeth system is on the strap, and the expanding element passes each spiral unit of zip fastener tooth, expanding element butt in the internal surface of each spiral unit. The utility model discloses an expanding element can strut each spiral unit like the screw that expands, give the certain cushion effect of zip fastener tooth for the zip fastener tooth can not flatten owing to exerting oneself too bigly, can keep the structure of zip fastener tooth lastingly, prolongs the life of zip fastener, and the explosion -proof can be strong.
Description
Technical field
The utility model relates to a kind of explosion-proof zipper.
Background technology
Slide fastener generally comprises strap and makes the zipper tooth on strap, existing integral type zipper tooth generally forms strip-spiral body by some spiral element are one-body molded, then be fixed on strap by suture, but due to each spiral element be smooth hollow oval shape, after repeatedly using, the spiral element meeting flattening deformation that part is firmly excessive, thus cause slide fastener dilatory not smooth and easily pop, even cannot use; In addition, bad location during suture, line can slide to end along smooth spiral element, thus can not fix zipper tooth well.
Utility model content
For the deficiencies in the prior art, the utility model is intended to provide a kind of explosion-proof zipper solved the problems of the technologies described above.
For achieving the above object, the utility model adopts following technical scheme:
A kind of explosion-proof zipper, it comprises strap, zipper tooth and expansion piece;
Zipper tooth is the strip-spiral body be made of one piece by some spiral element, and zipper tooth is made on strap, and expansion piece is through each spiral element of zipper tooth, and expansion piece is connected to the inner surface of each spiral element.
Preferably, the cross section of this expansion piece is circular, and its top and lower end are connected to the inner surface of each spiral element respectively.
Preferably, this expansion piece is single body.
Preferably, each spiral element ovalize, the middle part on its top is provided with a depressed part, and zipper tooth is made on strap by suture is fixed on the depressed part of each spiral element.
The beneficial effects of the utility model are at least as follows:
Expansion piece of the present utility model can strut each spiral element as setscrew, to the cushion effect that zipper tooth is certain, zipper tooth can not be flattened owing to exerting oneself excessive, the structure of zipper tooth can be kept enduringly, extend the service life of slide fastener, explosion-proof performance is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the utility model explosion-proof zipper.
Fig. 2 is the transversal profile schematic diagram of the explosion-proof zipper of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further:
Refer to Fig. 1 and Fig. 2, the utility model relates to a kind of explosion-proof zipper, and its better embodiment comprises strap 10, zipper tooth 20 and expansion piece 30.
Zipper tooth 20 is the strip-spiral body be made of one piece by some spiral element, and zipper tooth 20 is made on strap 10, and expansion piece 30 is through each spiral element of zipper tooth 20, and expansion piece 30 is connected to the inner surface of each spiral element.So, this expansion piece 30 can strut each spiral element as setscrew, to the cushion effect that zipper tooth 20 is certain, zipper tooth 20 can not be flattened owing to exerting oneself excessive, can keep the structure of zipper tooth 20 enduringly, extend the service life of slide fastener, explosion-proof performance is strong.
Preferably, the cross section of this expansion piece 30 is circular, and its top and lower end are connected to the inner surface of each spiral element respectively, realize buffering and the support of bearing up-down force.
Preferably, this expansion piece 30 is single body.
In the present embodiment, each spiral element ovalize, the middle part on its top is provided with a depressed part 26, and zipper tooth 20 is made on strap 10 by suture being fixed on the depressed part 26 of each spiral element.Suture can be fixed on the middle part on the top of each spiral element by depressed part 26 securely, enhances productivity, and makes zipper tooth 20 to be fixed on strap more securely.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
