Description

TECHNICAL FIELD

[0001] The utility model relates to zip fastener technical field, concretely is a wear -resisting nylon zip fastener. BACKGROUND

[0002] Zip fastener is a mechanical device used to connect and separate two pieces of material, usually composed of a series of teeth made of metal or plastic and a slider. Zip fasteners are widely used in clothing, bags, tents, car seats, and many other products. Zip fasteners are easy to use, can be quickly opened and closed, and are convenient for users to operate. After closing, it can effectively block air, moisture and dust, providing good sealing performance. High-quality zip fastener materials have strong wear resistance and long service life. Zip fasteners come in a variety of types, colors and sizes to meet different design needs. Zip fasteners can be used as decorative elements for clothing and accessories to enhance aesthetics.

[0003] The prospect of zip fasteners is relatively optimistic. With the continuous development of the clothing and accessories industry, the demand for zip fasteners is also growing.

[0004] Common zip fasteners can be roughly divided into three categories according to their materials and structures: metal zip fasteners, resin zip fasteners and nylon zip fasteners. Metal zip fasteners are made of copper, white copper or aluminum. Resin zip fastener teeth are made of polyester plastic and colored with dyes. They are produced by injection molding machines. Metal zip fasteners and resin zip fasteners are similar, with individual teeth arranged in combination. Some resin zip fastener teeth are connected on one side. Nylon zip fasteners are made of nylon monofilament that is wound around the center line by heat pressing.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Please refer to Figures 1-8 The utility model provides a technical scheme:

[0029] A kind of wear-resistant nylon zipper, including pull head 1, upper stop 2, lower stop 3 and two groups of tooth chain belts 4, two groups of tooth chain belts 4 upper end are equipped with upper stop 2, two groups of tooth chain belts 4 lower end are equipped with lower stop 3, two groups of tooth chain belts 4 are engaged connection, two groups of tooth chain belts 4 are equipped with pull head 1 on. Using pull head 1 can separate or make two groups of tooth chain belts 4 engage connection, two groups of tooth chain belts 4 are connected in the place needing to close respectively, and two groups of tooth chain belts 4 engage can close opening.

[0030] Further, the zipper tape 4 comprises a cloth tape 5, a reinforcing rib 6 and a zipper 7. The reinforcing rib 6 is arranged on the cloth tape 5. The zipper 7 is arranged on one side of the cloth tape 5 corresponding to the reinforcing rib 6. The side of the cloth tape 5 away from the reinforcing rib 6 is used as a connecting surface to connect with the fabric. The reinforcing rib 6 can increase the service life. The side of the cloth tape 5 away from the reinforcing rib 6 is connected with the fabric, which can prevent the tearing of the connection caused by the engagement of the two groups of zipper tapes 4. Although the stress of the engagement of the two groups of zipper tapes 4 is perpendicular to the direction of the zipper tape 4, the slider 1 is inevitably subjected to multiple directions of force when it slides up and down in actual use. The reinforcing rib 6 can prevent the tearing of the zipper caused by the force in the multiple directions. Thus, the service life is greatly improved.

[0031] Further, the zipper 7 comprises a plurality of zipper teeth 8 and a core wire 9. The plurality of zipper teeth 8 are woven on the core wire 9 by nylon monofilament.

[0032] Further, the zipper tooth 8 is made of a new type of wear-resistant nylon material. The side of the plurality of zipper teeth 8 is subjected to a flat surface processing. The unique flat processing makes the inner side of the zipper tooth 8 close to the slider 1 to be a plane. When the distance between the two groups of pull tabs 14 of the slider 1 is not changed, the friction can be greatly reduced, and the service life of the zipper can be significantly improved.

[0033] Further, the upper stop 2 comprises two square blocks 10. The two square blocks 10 are connected to the top ends of the two groups of zipper tapes 4, respectively. The two square blocks 10 are located on the side of the opening of the slider 1, and the two square blocks 10 are larger than the opening of the slider 1. The square blocks 10 cannot enter the slider 1, thereby playing a role in limiting the disengagement of the slider 1.

[0034] Further, the lower stop 3 comprises a first lower stop block 11 and a second lower stop block 13. The first lower stop block 11 and the second lower stop block 13 are connected to the ends of the two groups of zipper tapes 4 away from the upper stop 2. The first lower stop block 11 is provided with a plug-in hole 12 corresponding to the second lower stop block 13. The first lower stop block 11 and the second lower stop block 13 are connected by plug-in connection. The lower stop 3 is detachable. When used for clothes, the two groups of zipper tapes 4 can be separated. The slider 1 is attached to the side with the first lower stop block 11.

[0035] Further, the slider 1 comprises two groups of pull tabs 14 and a pull ring 17. One side of one group of pull tabs 14 is provided with the pull ring 17. The two groups of pull tabs 14 are provided with an intermediate connecting column 15 corresponding to the opening end. The two groups of pull tabs 14 are welded to the intermediate connecting column 15. The closed ends of the two groups of pull tabs 14 are provided with extrusion blocks 16. When the corresponding zipper teeth 8 on the two groups of zipper tapes 4 enter the slider 1 from the opening end, they are extruded at the extrusion blocks 16 and thus engaged with each other. When it is necessary to release the engaged state, the plurality of engaged zipper teeth 8 are separated by the intermediate connecting column 15, so that the zipper is unfastened.

[0036] Working principle: when the device is needed, the two groups of toothed belts 4 are connected to the clothes and other places needing to be opened, the puller 1 is slid to the lower stop 3, the first lower stop block 11 passes through the puller 1 and is inserted into the insertion hole 12 to pull the puller 1 away from the lower stop 3, so that the two groups of toothed belts 4 are engaged, and the opening can be closed, and when opening is needed, the puller 1 is moved along the toothed belt 4 towards the lower stop 3, so that the opening can be opened.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
