Description

Technical Field

[0001] The utility model relates to the technical field of alloy zippers, in particular to a wear-resistant and smooth alloy zipper. Background Art

[0002] A zipper is a fastener consisting of two strips, each with a row of zipper teeth, used to connect the edges of an opening. The two rows of zipper teeth can be pulled into an interlocking position through the zipper head to close the opening.

[0003] Nowadays, zipper teeth on the market are generally made of plastic or metal. Plastic zippers have low production costs but poor strength, while alloy zippers have poor corrosion resistance and anti-jamming properties. During the use of alloy zippers, the two rows of zipper teeth are often closed smoothly, but there will be jams when pulling down to open and close, resulting in the alloy zipper not being pulled smoothly, thereby reducing its service life. Utility Model Content

[0004] The utility model provides a wear-resistant and smooth alloy zipper, which can overcome certain defects of the prior art.

[0005] According to the utility model, a wear-resistant and smooth alloy zipper comprises two cloth tapes, a plurality of mutually engaging zipper teeth are fixedly provided on opposite sides of the two cloth tapes, a convex portion and a concave portion cooperating with adjacent zipper teeth are respectively provided on the top and bottom of the meshing ends of the zipper teeth, an inclined groove is provided on the opposite sides of the convex portion, and a roller is rotatably provided on the top of the groove; a zipper head for opening and closing the zipper teeth on both sides is slidably provided between the two cloth tapes.

[0006] Preferably, a top block for pushing open the mutually engaged zipper teeth is fixedly provided inside the zipper head, and a guide block for cooperating with the groove is fixedly provided at the bottom of the top block.

[0007] With the above structure, the guide block can enter the groove first, and the guide block can separate the zipper teeth better and more stably through the inclined setting of the groove and the limiting and guiding effect of the groove on the guide block.

[0008] Preferably, a clamping groove for installing the cloth tape is provided at one end of the zipper tooth away from the protrusion.

[0009] The above structure facilitates the installation and replacement of the zipper teeth.

[0010] Preferably, a first inclined surface for the top block to be inserted into is provided on the inner side of the protrusion and the zipper teeth, and the inclination angle of the first inclined surface is the same as that of the groove.

[0011] The above structure facilitates the guide block to be quickly inserted into the mutually engaged zipper teeth to separate the zipper teeth.

[0012] Preferably, a mounting groove for mounting a roller is provided at the top of the groove, the top and side walls of the roller are flush with the top of the convex portion and the side walls of the groove respectively, and a second inclined surface is provided between the mounting groove and the groove.

[0013] Through the above structure, the guide block is quickly inserted into the groove through the rotation of the roller, so that the zipper teeth that are engaged with each other are pre-separated.

[0014] Preferably, the zipper teeth are integrally cast with a copper-zinc alloy layer, and a PPT modified material layer is provided on the outer wall of the copper-zinc alloy layer.

[0015] Through the above structure, the inside of the zipper teeth is made of metal material, and the outside is provided with a PPT modified material layer, which not only improves its strength but also ensures the smoothness of the zipper teeth when opening and closing.

[0016] The beneficial effects of the utility model are as follows:

[0017] Compared with the prior art, the utility model firstly inserts the guide block into the groove quickly through the roller for pre-separation, and then squeezes the convex part outward through the top block, so that the guide block quickly separates the mutually engaged zipper teeth, avoiding the situation that the alloy zipper cannot be pulled smoothly due to the jamming when pulling down to open and close, thus reducing the service life of the zipper.
