[0002] Drain pipes are the main component in our drainage system. There are many types of drain pipes, and there are different types of drain pipes according to their different uses, such as concrete drain pipes for urban drainage and sewage, PVC drain pipes for household use, etc. Some also use steel drain pipes, etc. In the installation of drain pipes, the connection of the drain pipes is the most important part.

[0003] After searching the Chinese patent with the publication number CN219571226U, a PVC drainage pipe that is easy to connect is disclosed, including: water pipe 1 and water pipe 2; a connecting pipe, fixedly installed on the outer surface of one end of the water pipe 1, and the outer surface of the connecting pipe is fixedly sleeved with multiple sealing rings; two sliders, both fixedly installed on the outer surface of one end of the connecting pipe; two slide grooves, both opened inside one end of the water pipe 2; an annular groove, opened inside the water pipe 2, and the annular groove is connected to the slide groove. The connecting pipe installed at one end of the water pipe 1 is embedded into the inside of the slide groove opened in the water pipe 2 through two sliders, and then the water pipe 1 is rotated inside the annular groove until the slider feels resistance and hits the positioning block, so that the water pipe 1 and the water pipe 2 are installed and connected together. Multiple sealing rings are fixedly installed on the outer surface of the connecting pipe, which can better prevent water leakage at the connection between the water pipe 1 and the water pipe 2, and better improve the sealing performance.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The above patent uses multiple sealing rings for sealing, and its sealing effect is good, but the connection method for two drain pipes is too simple. It is only fixedly connected by limiting holes and limiting rods. The connection method is general. During long-term use, it is easy to cause the connection to be not particularly firm, thereby affecting the use of the drain pipe. Therefore, there are certain limitations. Utility Model Content
