[0002] The main component of PVC pipe is polyvinyl chloride, and a material added with other components to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is deeply loved, quite popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in just 1995, the production volume of PVC pipes in Europe was about five million tons, and its consumption volume was five million three hundred thousand tons.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fire-resistant and flame-retardant PVC pipe, including a pipe body 8, which is commonly used in the tap water supply system of buildings. It has good corrosion resistance and pressure resistance, can be used for long-term operation, and will not be corroded by chemical substances in water. A connecting pipe 1 is provided on one side of the pipe body 8, and its main function is to connect two groups of pipes, facilitating their installation and disassembly, thus greatly improving the practicability of the PVC pipe. An installation cavity 9 is arranged inside the connecting pipe 1, and its main function is to fix the interfaces of two groups of PVC pipes through the internal groove 10, facilitating the connection of the connecting ring 7. Grooves 10 are arranged at both ends inside the installation cavity 9 to enhance stability. The design of the groove 10 can enhance the stability of the bottle body, making it stand more firmly in a certain place. This design utilizes the stability principle of a triangle. An upper mounting rod 11 is arranged at the top of the connecting pipe 1, and its main function is to fix and limit the interface of another group of pipes through rotation by the upper clamping plate 13, thereby making the PVC pipe more stable in use. The lower mounting rod 16 penetrates through the bottom end of the connecting pipe 1, and its main function is to drive the lower clamping plate 14 to move in position through rotation to fix and limit the interface of another group of pipes, thereby making the PVC pipe more stable in use. An upper wire sleeve 12 is sleeved on the surface of the upper mounting rod 11, and its main function is to limit the upper mounting rod 11 so that it is not easily detached, thereby making the fixation more stable. A lower wire sleeve 15 is sleeved on the surface of the lower mounting rod 16, and its main function is to limit the lower mounting rod 16 so that it is not easily detached, thereby making the fixation more stable. A lower clamping plate 14 is arranged at the top end of the lower mounting rod 16. Its main function is to rotate through the lower mounting rod 16 to fix and limit the interface of another group of pipes, thereby making the connection of the two groups of pipes more stable.

[0021] At the bottom end of the upper mounting rod 11, there is an upper clamping plate 13. Its main function is to rotate through the upper mounting rod 11 to fix and limit the interface of another group of pipes, so as to make the connection of the two groups of pipes more stable. At both ends on one side of the pipe body 8, there are fixed plates 3. Their main function is to be fixed to the connecting pipe 1 through the fixing bolts 2, so as to make the connection of the pipes more stable. The fixing bolts 2 penetrate through one side of the fixed plates 3. Their main function is to fix the pipe body 8 and the connecting pipe 1, so that the PVC pipes are more stable in use. Fixed sleeves 4 are sleeved on the surfaces of the fixing bolts 2. Their main function is to limit the fixing bolts 2 to prevent them from falling off, so that the PVC pipes are more stable. Connecting rings 7 are fixedly arranged at both ends of the pipe body 8. The connecting rings 7 have magnetism. Their main function is to connect with the connecting rings 7 of the interface of another group of pipes, so as to make the installation of the pipes more convenient. Fire-resistant layers 5 are arranged on the surfaces of the pipe bodies 8. Their main function is to greatly enhance the fire-resistant performance of the pipes and greatly improve the protection performance of the pipes. Flame-retardant layers 6 are arranged inside the fire-resistant layers 5. Their main function is to greatly improve the flame-retardant performance of the pipes, so as to greatly improve the protection performance of the pipes.

[0022] Working principle: When the fire-resistant and flame-retardant PVC pipes are needed to work, first, the connecting pipe 1 and the pipe body 8 can be fixed through the cooperation of the fixing bolts 2, the fixed sleeves 4 and the fixed plates 3, so that the connecting ring 7 on one side of the pipe body 8 is positioned in the groove 10. Then, by putting another group of PVC pipes into the connecting pipe 1, the connecting ring 7 of the other group of PVC pipes is positioned through the groove 10, so that the two connecting rings 7 are connected. Then, by rotating the upper mounting rod 11 and the lower mounting rod 16 to drive the upper clamping plate 13 and the lower clamping plate 14 to move in position, the upper clamping plate 13 and the lower clamping plate 14 limit and fix the connecting part of the other group of PVC pipes. When disassembling, rotate the upper mounting rod 11 and the lower mounting rod 16 to cancel the limit on the connecting part of the other group of PVC pipes and take it out.
