As shown in fig. 2 and 3, a connecting hole 31 is formed in the second flange 3 corresponding to the connecting rod 21 of the first flange 2, a central axis of the connecting hole 31 in the length extending direction is an arc line, the connecting hole 31 allows the connecting rod 21 to slide inside, and the connecting holes 31 are uniformly arranged on the second flange 3 in the circumferential direction. The inner walls of the connecting holes 31 on both sides in the width extending direction are respectively provided with slide grooves 32. The second flange 3 faces the surface of the pipe body 1 and is provided with a notch 33 at one end of the connecting hole 31 along the length extending direction, the notch 33 is communicated with the connecting hole 31, and the width of the notch 33 is larger than the width between the groove bottoms of the sliding grooves 32 respectively positioned on the side walls at the two sides of the connecting hole 31. The second flange 3 is further provided with a limiting assembly 4 for limiting the relative rotation of the first flange 2 connected with the second flange, and the limiting assembly 4 comprises a sliding block 42 and a compression spring 41. The central axis of the sliding block 41 in the length extending direction is an arc line, two sides of the sliding block 42 are respectively and integrally provided with a projection 421 for matching with the sliding groove 32, and the projection 421 is located at the end of the sliding block 42. The user inserts the projection 421 of the sliding block 42 into the notch 33 of the second flange 3, and then the user moves the sliding block 42 toward the sliding slot 32, so that the projection 421 is inserted into the sliding slot 32 and the sliding block 42 slides in the connecting hole 31.

The end face of the slide block 42 close to one end of the notch 33 of the second flange 3 is welded with a compression spring 41, and one end of the compression spring 41 far away from the slide block 42 is welded on the wall face of the connecting hole 31 of the second flange 3 close to one end of the notch 33. And the natural length of the compression spring 41 is longer than the length of the connection hole 31, so that the compression spring 41 located between the slider 42 and the wall surface of the connection hole 31 is known to be in a compressed state. The second flange 3 faces the surface of the pipe body 1 and is located at the notch 33, a limiting plate 34 is fixedly connected with the notch 33 through a bolt, two ends of the limiting plate 34 are respectively fixedly connected with two sides of the notch 33 of the second flange 3 through bolts, and the notch 33 is completely covered by the limiting plate 34.

As shown in fig. 4, a sealing groove 35 for the annular protrusion to be inserted into is formed on the surface of the second flange 3 facing away from the pipe body 1 and corresponding to the annular protrusion of the first flange 2, and the sealing groove 35 is concentric with the second flange 3. And the surface of the second flange 3 opposite to the pipe body 1 is also provided with two annular grooves 36 concentrically with the sealing groove 35, and the two annular grooves 36 are concentric. The inner cavity of one end of the tube body 1 close to the second flange 3 is of a stepped structure which can be matched with the stepped insertion tube 24.

When a user desires to connect two adjacent drain pipes, as shown in fig. 1 and 2, the user inserts the insert pipe 24 at one end of one of the drain pipes adjacent to the first flange 2 into the stepped inner cavity at the other end of the drain pipe adjacent to the second flange 3. Then, the user slides the sliding block 42 on the second flange 3 to a side close to the notch 33, and inserts the connecting rod 21 of the drain pipe adjacent to the sliding block into the connecting hole 31 of the second flange 3, and rotates the first flange 2 in a direction in which the connecting rod 21 is far away from the notch 33, because the length of the connecting rod 21 is the same as the thickness of the second flange 3, the wall thickness of the second flange 3 is inserted between the connecting rod 21 and the first flange 2, and thus the fixed connection between two adjacent drain pipes is realized. And because the compression spring 41 is in a compressed state, the compression spring 41 applies a force to the sliding block 42 in a direction close to the connecting rod 21, so that the sliding block 42 is pressed against the connecting rod 21, the probability of relative rotation between the first flange 2 and the second flange 3 is reduced, and the connection relationship between two adjacent drain pipes is also reduced.
