[0034] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1: A high temperature resistant zipper, see Figures 1 to 4 , including a chain belt 1, a chain tooth 3, a chain head 4, a U-shaped rod 5, a pull tab 6 and a limiting structure 7; the chain belt 1 is sewn on both sides of the chain tooth 3; the chain head 4 is meshed and connected to the chain tooth 3; the U-shaped rod 5 is rotatably arranged on the chain head 4; one end of the pull tab 6 is fixedly connected to the open end of the U-shaped rod 5; two limiting structures 7 are symmetrically arranged on the chain head 4;

[0036] The limiting structure 7 includes a connecting block 701, an arc-shaped bottom plate 702 and an arc-shaped plastic plate 703; the connecting block 701 is fixed on the chain head 4; the arc-shaped bottom plate 702 is fixed on the top of the connecting block 701; the two arc-shaped plastic plates 703 are respectively arranged at both ends of the arc-shaped bottom plate 702; wherein, the arc-shaped bottom plate 702 and the two arc-shaped plastic plates 703 constitute an arc-shaped clamping ring, and the straight section of the U-shaped rod 5 is clamped into engagement with the arc-shaped clamping ring.

[0037] The present invention has the advantages of limiting the position of the U-shaped rod 5 and thus limiting the position of the pull tab 6 by providing the connecting block 701, the arc-shaped bottom plate 702 and the arc-shaped plastic plate 703, thereby keeping the pull tab 6 stable, and solving the problem that the pull tab 6 may shake when the clothes are worn, and the pull tab 6 may get stuck, thereby affecting the pulling.

[0038] Specifically, the two chain belts 1 are respectively sewn with high-temperature resistant sleeves 2; wherein, the high-temperature resistant sleeves 2 are made of DuPont sand thread to enhance the high-temperature resistance of the zipper.

[0039] Furthermore, the outer ends of the two arc-shaped plastic plates 703 are respectively configured as arc-shaped surfaces 7031 , so that when the straight section of the U-shaped rod 5 is clamped with the arc-shaped clamping ring, the straight section of the U-shaped rod 5 is easily clamped into the two arc-shaped plastic plates 703 .

[0040] Furthermore, the inner sides of the two curved plastic plates 703 are respectively provided with abutment springs 704, which abut against the straight section of the U-shaped rod 5. The cross section of the abutment springs 704 is designed to be curved, and the arched ends of the abutment springs 704 contact the straight section of the U-shaped rod 5.

[0041] The present invention has the advantage of further limiting the position of the straight section of the U-shaped rod 5 inserted into the arc-shaped clamping ring by providing the abutting spring piece 704, thereby further maintaining the stability of the U-shaped rod 5.

[0042] Working Principle: When using the device of the present invention, after the chain link 4 is pulled into place, the pull tab 6 is laid flat. The straight section of the U-shaped rod 5 is inserted into the curved snap ring through the opening between the two curved plastic plates 703. The curved contact spring 704 is squeezed and bent by the straight section of the U-shaped rod 5 until the straight section of the U-shaped rod 5 is inserted into the curved snap ring. The contact spring 704 is in a squeezed state and presses against the straight section of the U-shaped rod 5, thereby limiting the pull tab 6 and keeping it stable. To open the zipper, lift the pull tab 6, the straight section of the U-shaped rod 5 moves out of the curved snap ring, and the chain link 4 is pulled.

[0043] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
