[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0021] In the description of the present utility model, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Referring to Figure 1 and Figure 2 , a PVC quick door sealing zipper provided by the present utility model includes two slide rails 1, two PVC chains 2, and a plurality of chain teeth 3. The two PVC chains 2 are respectively connected to both sides of the PVC quick door 4. A plurality of mounting holes 201 are vertically formed in the PVC chains 2. The chain teeth 3 pass through the mounting holes 201 and are fixedly connected to the PVC chains 2. The chain teeth 3 can be slidably inserted into the slide rails 1. The two PVC chains 2 are respectively slidably connected to the two slide rails 1 through the chain teeth 3. Since the chain teeth 3 on the PVC chains 2 are located in the slide rails 1, the gap between the PVC chains 2 and the slide rails 1 becomes smaller, and the safety performance and sealing performance are improved.

[0024] The slide rail 1 is a semi-enclosed structure. The chain teeth 3 wrap the outer side of the PVC chain 2. The chain teeth 3 on the outer side of the PVC chain 2 can only be inserted from the end of the slide rail 1 and slidably connected thereto, and it is impossible to pull the PVC chain 2 out of the slide rail 1 from the front, further playing a role in safety protection. The chain teeth 3 are made of POM material, which is an engineering plastic with excellent comprehensive performance and has good physical, mechanical, and chemical properties, especially excellent friction resistance. In this embodiment, the chain teeth 3 are fixedly connected to the PVC chains 2 by an injection molding process through the mounting holes 201, enhancing the connection strength between the chain teeth 3 and the PVC chains 2.

[0025] The PVC fast door 4 and the PVC chain 2 are connected by hot melt welding, and they can also be connected by bonding or sewing. A connecting groove 202 is formed on the inner side of the PVC chain 2, and the PVC fast door 4 is embedded in the connecting groove 202, so that the PVC fast door 4 and the PVC chain 2 can be integrated into a complete structure.

[0026] Two fabric layers are provided inside the PVC chain 2, which keeps the PVC chain 2 with a relatively low thickness while ensuring that the structure has high toughness and strength, thus reducing the weight.

[0027] During use, the two PVC chains 2 are welded to both sides of the PVC fast door 4, and the slide rails 1 are installed on the door frames on both sides of the PVC fast door 4. Then, the PVC chains 2 are inserted into the slide rails 1 from the ends of the slide rails 1 through the chain teeth 3 on the outer sides for sliding connection, completing the installation of the PVC fast door 4, and improving the sealing performance and safety performance of the PVC fast door 4.

[0028] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
