Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a high temperature resistant zipper. Background Art

[0002] Zippers are daily necessities commonly used in life, mainly installed on clothing, bags, etc. Zippers are roughly divided into closed zippers and open zippers according to needs. A closed zipper is provided with an upper stop and a lower stop at both ends of the zipper, and the zipper head slides between the upper stop and the lower stop, and one end of the lower stop cannot be separated, so the entire zipper cannot be divided into two zipper tapes. For an open zipper, a stop is provided at one end, and an opening and closing device for fully opening the zipper is provided at the other end. The opening and closing device mainly includes a zipper tape box set on one side of the two zipper tapes that can bite each other, a box rod protruding from the box, and a zipper tape insertion rod set on the other side. When operating an open zipper, it is mainly to hold the box rod and the zipper tapes on both sides of the insertion rod, and insert or pull the insertion rod relative to the box.

[0003] For example, Chinese patent CN209788676U discloses a zipper, which has a pair of zipper tapes formed by zipper teeth arranged on a pair of zipper tapes, and opening and closing tools are arranged at the ends of the zipper tapes in the length direction, and the opening and closing tools are used to connect or separate the respective ends of the pair of zipper tapes. The opening and closing tools have a box body arranged on the zipper tape on one side of the pair of zipper tapes, a box rod arranged on the zipper tape on one side and protruding from the box body, and an insertion rod arranged on the zipper tape on the other side of the pair of zipper tapes.

However, when used for a long time, the zipper puller may break and fall off. However, generally, zipper pullers and clothes are matching products, so even if they are replaced, it will affect their overall beauty and coordination. Therefore, the present application proposes a high-temperature resistant zipper to solve the above problem. Utility Model Content
