Description

Plastic-steel electroplated tooth zipper

Technical Field

The utility model belongs to the technical field of machinery, a plastic steel electroplating tooth zip fastener is related to.

Background

The zipper teeth of the plastic-steel zipper are made of plastic-steel materials, and compared with the plastic zipper teeth, the plastic-steel zipper teeth are higher in hardness, more resistant to high temperature, wear resistant, sun resistant and anti-aging.

As disclosed in the chinese utility model [ patent No. 201520677727.3 ], a plastic steel double-sided zipper tooth zipper is provided with plastic steel zipper teeth on left and right cloth tapes of the zipper to form left and right zipper blanks; the left and right sides of the left and right cloth belts are provided with zipper teeth; when the article is sewed, the article is sewed in the middle of the left and right zipper blanks, so that the zipper teeth arranged on the left and right sides of the cloth belt form upper and lower zipper teeth, and the upper and lower zipper teeth of the left and right cloth belts are butted to form a front zipper and a back zipper.

The zipper is applied to clothes mostly, but the zipper and the zipper teeth of the common zipper have the same defect that the zipper teeth are symmetrical up and down, when the zipper teeth are meshed together, if the zipper tape is bent, the adjacent zipper teeth are mutually extruded together, so that the zipper tape cannot be bent too much, the clothes cannot be folded well, the elegant feeling of some light and thin clothes cannot be completely displayed, and if the zipper tape is bent by force, the zipper teeth can be dislocated, so that the zipper is damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above problems in the prior art, the plastic steel electroplated tooth zipper is provided, the zipper is easier to bend in front, and the plastic steel electroplated tooth zipper is more suitable for being applied to soft clothes.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a tooth zip fastener is electroplated to plastic steel, includes chain cloth and chain tooth, and chain tooth equidistance is arranged at the chain cloth edge, its characterized in that, the chain tooth includes tooth head and tooth afterbody, the tooth head divide into upper strata and lower floor, the lower floor has and is curved inlay card portion, and inlay card portion both sides are opened flutedly, the upper strata is the set-square of closed angle towards chain tooth front end, upper strata and lower floor formula structure as an organic whole, the tooth afterbody is opened there is the draw-in groove that supplies the chain cloth embedding, the electroplating of chain tooth upper surface has the one deck metal level.

The metal level of electroplating is more smooth, because the upper surface of chain tooth often will draw zipper head inner chamber upper wall friction, so, because glossy metal level both can reduce frictional strength, the plastic material is compared to the metal level material moreover, and is more wear-resisting. When the zipper is bent towards the upper layer of the zipper teeth, the zipper can be bent to a certain angle until the side edge of the triangular plate is abutted against the side edge of the adjacent zipper teeth. Because the gap between the adjacent triangular plates is large enough, the front surface is easier to bend and the bending amplitude is larger than the back surface.

The edge of the chain cloth is embedded into the clamping groove and fixed through hot pressing.

Furthermore, the bottom of the clamping groove is an arc-shaped surface, a cylindrical clamping head is arranged at the edge of the chain cloth, and the clamping head is embedded into the arc-shaped surface.

Furthermore, the thickness of the upper layer is 0.8-1mm, and the thickness of the lower layer is 1-1.2 mm.

Further, the thickness of the metal layer is 6-8 um.

Further, the front end of the upper layer is flush with the front end of the lower layer.

Further, the angle of the sharp corner of the triangular plate is 30-35 degrees.

Compared with the prior art, the plastic-steel electroplated tooth zipper has the advantages that:

1. the tooth head part of the zipper tooth is divided into two layers, and the upper layer is the triangular plate, so that the space between the adjacent triangular plates is large enough, and the space for the zipper tooth to bend upwards is larger.

2. The upper surface is electroplated with a metal layer to improve the wear resistance.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 5, the plastic-steel electroplated tooth zipper comprises a zipper cloth 1 and zipper teeth 2, the zipper teeth 2 are arranged at the edge of the zipper cloth 1 at equal intervals, the zipper teeth 2 comprise a tooth head part 21 and a tooth tail part 22, the tooth head part 21 is divided into an upper layer and a lower layer, the lower layer is provided with an arc-shaped clamping and embedding part 23, grooves are formed in two sides of the clamping and embedding part 23, the upper layer is a triangular plate 24 with a sharp corner facing the front end of the zipper teeth 2, and the sharp corner angle of the triangular plate 24 is 30-35 °. The upper layer and the lower layer are of an integrated structure, the tooth tail part 22 is provided with a clamping groove 25 for embedding the zipper cloth 1, and the upper surface of the zipper tooth 2 is electroplated with a metal layer 26.

The bottom of the clamping groove 25 is an arc-shaped surface, the edge of the chain cloth 1 is provided with a cylindrical clamping head 11, and the clamping head 11 is embedded into the arc-shaped surface.

The thickness of upper strata is 0.8-1mm, the thickness of lower floor is 1-1.2mm, the thickness of metal level 26 is 6-8um, and the front end of upper strata flushes with the front end of lower floor.

The electroplated metal layer 26 is smoother, and the upper surface of the zipper teeth 2 often rubs with the upper wall of the inner cavity of the zipper puller, so that the friction strength can be reduced due to the smooth metal layer 26, and the material of the metal layer 26 is more wear-resistant than that of plastic. When the slide fastener is bent toward the upper layer of the element 2, it can be bent to a certain angle until the side edge of the triangle 24 abuts against the side edge of the adjacent element 2. Because the gap between adjacent triangles 24 is large enough, the front side bends more easily and the magnitude of the bending is greater than the back side.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
