[0022] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: an indoor drainage pipe joint that is easy to replace, including a connecting pipe 1 located between two drain pipes 2 on both sides. Rotating connections are respectively provided on both sides of the connecting pipe 1 with extension pipes 3. A sealing connection assembly is arranged on the outer side of the extension pipe 3, and the sealing connection assembly is used to ensure the sealing performance between the connecting pipe 1 and the extension pipe 3. A clogging prevention assembly 4 is arranged inside the connecting pipe 1, and the clogging prevention assembly 4 is used to prevent the connecting pipe 1 from being clogged during use.

[0023] As a further preference of this embodiment, annular grooves 11 are respectively opened at both ends of the connecting pipe 1. One end of the extension pipe 3 is provided with an annular slider 31. An external thread is arranged on the outer circumferential surface of the annular slider 31, and an internal thread is opened on the inner side wall of the annular groove 11. The annular slider 31 is threadedly connected with the annular groove 11. By rotating the extension pipe 3, the external thread of the annular slider 31 is threadedly engaged with the internal thread of the annular groove 11, so that the extension pipe 3 moves along the direction of the annular groove 11, thereby adjusting the protruding distance of the extension pipe 3 relative to the connecting pipe 1 to adapt to the distance between the two drain pipes 2 on both sides.

[0024] As a further preference of this embodiment, a sealed connection is provided between the extension pipe 3 and the connecting pipe 1 to prevent liquid leakage.

[0025] Please refer to Figures 3 to 4 , the sealing connection assembly includes a clamping sleeve 32 fixedly arranged at the other end of the extension pipe 3. The clamping sleeve 32 is sleeved on the outer circumference of the drain pipe 2. A number of arc-shaped sliders 33 are arranged on the inner circumference of the clamping sleeve 32. A number of threaded rods 34 are passed through the circumferential surface of the clamping sleeve 32. The threaded ends of the threaded rods 34 pass through the clamping sleeve 32 and are rotatably connected to the corresponding arc-shaped sliders 33. By rotating the threaded rods 34, the corresponding arc-shaped sliders 33 are driven to move, so that the arc-shaped sliders 33 are closely attached to the outer side of the drain pipe 2.

[0026] As a further preference of this embodiment, sealing gaskets 35 are fixedly connected to the inner walls of the arc-shaped sliders 33. A number of the sealing gaskets 35 are combined into a complete annular sealing gasket, and the annular sealing gasket can be closely attached to the outer side of the drain pipe 2 to prevent liquid leakage.

[0027] As a further preference of this embodiment, the anti-blocking component 4 includes a support rod 41 with two ends respectively rotatably connected to the connecting pipe 1. A plurality of arc-shaped cleaning rods 42 are arranged in an array on the circumferential outer wall of the support rod 41. A filter screen 43 is fixedly arranged in the connecting pipe 1. The arc-shaped cleaning rods 42 are attached to the inner wall of the filter screen 43. When the support rod 41 rotates, it drives the arc-shaped cleaning rods 42 to rotate, so as to be attached to and scrape the inner wall of the filter screen 43, so as to remove the impurities attached to the filter screen 43 and prevent the filter screen 43 from being blocked.

[0028] As a further preference of this embodiment, a plurality of force-receiving plates 44 are also arranged in an array on the circumferential outer wall of the support rod 41. The force-receiving plates 44 and the arc-shaped cleaning rods 42 are arranged alternately. When water flows through the connecting pipe 1, it beats the force-receiving plates 44, causing the force-receiving plates 44 to drive the support rod 41 to rotate.

[0029] The working principle of the present utility model:

[0030] Place the connecting pipe 1 between the two drain pipes 2, rotate the extension pipe 3, under the action of thread fit, the extension pipe 3 moves outward, so that the two clamping sleeves 32 are respectively connected to one end of the corresponding drain pipe 2, and the connecting pipe 1 is fixed to complete the connection work of the two drain pipes 2. Then rotate the threaded rod 34 to drive the arc-shaped slider 33 to move. The arc-shaped slider 33 squeezes the sealing gasket 35 inward, thereby improving the sealing performance at the connection between the clamping sleeve 32 and the drain pipe 2. During the drainage process, sundries are filtered by the filter screen 43, and at the same time, the water flow impacts the force-receiving plates 44, driving the support rod 41 to rotate, so that the arc-shaped cleaning rods 42 rotate to scrape the inner side of the filter screen 43, avoiding blockage of the filter screen 43 caused by the filter. Reverse-rotate the extension pipe 3, and the clamping sleeve 32 can be separated from the drain pipe 2, and a new connecting pipe 1 can be replaced.

[0031] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model.
