Description

Technical Field

[0001] This utility model relates to the field of zipper head technology, and in particular to a double-sided zipper. Background Technology

[0002] Zipper pulls are categorized into the following types based on whether they are made of nylon, metal, or rubber: Nylon zipper pulls are generally semi-circular in shape. Because nylon zippers only have teeth on one side, the fabric seam is wider on one side and narrower on the other. Metal zipper pulls have sharp or prominent edges. Because they have teeth on both sides, the fabric seam on both sides is the same width. Plastic zipper pulls are also semi-circular or butterfly-shaped. Because they have teeth on both sides, the fabric seam on both sides is the same width.

[0003] The existing double-sided zipper pulls still have the following problems when in use:

[0004] 1. Existing double-sided zipper heads may be damaged during long-term use. Since the zipper head is a single piece, it is not convenient to replace it after it is damaged, which affects the long-term use of the zipper head.

[0005] 2. When using existing double-sided zipper heads, the zipper only serves to open and close, resulting in poor aesthetics and practicality. Utility Model Content

[0006] The purpose of this invention is to provide a double-sided zipper that solves the problems mentioned above.

[0007] To achieve the above objectives, a double-sided zipper is provided, including a zipper head composed of an upper and a lower assembly, with a guide mechanism on the upper side. A fixing plate is fixedly connected between the upper and lower assemblies. The guide mechanism includes a U-shaped limiting plate and a U-shaped partition. The U-shaped partition is fixedly connected to the upper and lower assemblies. The U-shaped limiting plate is composed of two hinged parts, with fixing blocks at both ends. One end of the fixing block is fixedly connected to the lower assembly, and the other end is in contact with the upper assembly. A positioning groove is provided inside the U-shaped limiting plate, and a connecting positioning groove is embedded in the outer side of the fixing block. A pull tab is provided between the U-shaped limiting plate and the U-shaped partition. The pull tab is composed of a connecting part and a decorative part. A limiting rod is fixedly connected to the upper end of the connecting part. A rotating shaft is rotatably connected between the connecting part and the decorative part. An installation groove is provided in the middle of the decorative part, and a decorative box is installed in the installation groove.

[0008] According to the aforementioned double-sided zipper, a through hole is provided on the U-shaped limiting plate located on one side of the upper assembly block, and a bolt is provided in the through hole. The bolt passes through the through hole and is threadedly connected to the upper assembly block.

[0009] According to the aforementioned double-sided zipper, rubber pads are fixedly connected to the U-shaped limiting plates located on both sides of the U-shaped partition. There are four rubber pads, which are evenly distributed.

[0010] According to the aforementioned double-sided zipper, the upper end of the decorative part is fixedly connected to a rotating shaft, and the bottom of the connecting part is rotatably connected to the rotating shaft.

[0011] According to the aforementioned double-sided zipper, the pull tab is connected to a U-shaped limiting plate via a limiting rod.

[0012] According to the aforementioned double-sided zipper, the zipper head, guide mechanism, and pull tab are all made of metal.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, by setting a U-shaped limiting plate and a U-shaped partition on the zipper head, when installing the zipper, flip one side of the U-shaped limiting plate, then place the limiting rod at the upper end of the pull tab on both sides of the U-shaped partition, and position it between the U-shaped limiting plate and the zipper head. Then, fix the U-shaped limiting plate to the zipper head with bolts. The operation is convenient. If the zipper is damaged, simply remove the bolts and replace the zipper. The operation is convenient and does not require disassembling the entire zipper head.

[0015] 2. Compared with existing technologies, by providing a detachable decorative box on the pull tab, different patterns can be matched according to personal preference during use. At the same time, the decorative box can increase the friction between the pull tab and the hand, making it easier for the zipper to open and close. Attached Figure Description
