[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , an anti-seepage connection structure for municipal water supply and drainage pipes, including a fixed pipe 1. A connecting pipe 2 is inserted into the interior of the fixed pipe 1. A fixed block 3 is fixedly connected to the outer side of the fixed pipe 1. A limiting sleeve 31 is rotatably connected to the outer side of the fixed block 3. The limiting sleeve 31 is rotatably connected to the fixed pipe 1. The limiting sleeve 31 is threadedly connected to the connecting pipe 2. Through the design of the limiting sleeve 31, the connecting pipe 2 can be limited. An annular groove 32 is formed in the interior of the limiting sleeve 31. The annular groove 32 is slidably connected to the fixed block 3. Through the design of the annular groove 32, the displacement of the limiting sleeve 31 during rotation can be prevented.

[0022] Please refer to Figures 2-4 , a fixing plate 4 is fixedly connected to the inner wall of the fixed pipe 1. A sleeve 41 is fixedly connected to the side of the fixing plate 4 close to the connecting pipe 2. A sliding rod 42 is slidably connected to the interior of the sleeve 41. A limiting ring 43 is fixedly connected to the interior of the sleeve 41. The limiting ring 43 is slidably connected to the sliding rod 42. Through the design of the limiting ring 43, the sliding rod 42 can be limited. A spring 44 is arranged in the interior of the sleeve 41.

[0023] Please refer to Figures 2-4 , one end of the spring 44 contacts the sliding rod 42, and the other end of the spring 44 contacts the sleeve 41. Through the design of the spring 44, the sealing ring 45 can be driven to fit the connection between the connecting pipe 2 and the fixed pipe 1. A sealing ring 45 is fixedly connected to the end of the sliding rod 42 far from the sleeve 41. The sealing ring 45 is slidably connected to the fixed pipe 1. The sealing ring 45 contacts the connecting pipe 2. Through the design of the sealing ring 45, the sealing performance between the connecting pipe 2 and the fixed pipe 1 can be increased.

[0024] The specific implementation process of the present invention is as follows: During use, the connecting pipe 2 is inserted into the fixed pipe 1, and then the limiting sleeve 31 is rotated, so that the limiting sleeve 31 rotates on the fixed block 3, and a threaded movement occurs between the limiting sleeve 31 and the connecting pipe 2, so that the limiting sleeve 31 limits the connecting pipe 2, and the connecting pipe 2 can be kept stable after being installed with the fixed pipe 1;

[0025] When installing the connecting pipe 2 to the fixed pipe 1, the connecting pipe 2 is brought into contact with the sealing ring 45. When the connecting pipe 2 continues to move, it will drive the sealing ring 45 to move, causing the sealing ring 45 to drive the sliding rod 42 to slide within the limiting ring 43, causing the sliding rod 42 to squeeze the spring 44. Then, the elastic force of the spring 44 can be used to drive the sliding rod 42 to move, causing the sliding rod 42 to drive the sealing ring 45 to fit the connection between the connecting pipe 2 and the fixed pipe 1, thereby effectively increasing the sealing performance between the connecting pipe 2 and the fixed pipe 1, and effectively increasing the anti-seepage effect after the installation of the connecting pipe 2.
