[0029] See also Figures 1 to 8 The drainage pipe joint of the present invention includes a pipe joint body 1 and two clamping clamps 22 pressed outside the pipe joint body 1. The pipe joint body 1 is composed of a first pipe joint 11 and a second pipe joint 12 that are threadedly connected to each other, and at least two sealing rings 21 are arranged on the outer sleeve of the pipe joint body 1; the two clamping clamps 22 are pressed outside the sealing ring 21, and the two clamping clamps 22 are connected to each other through a first arc cover 23 and a second arc cover 24, the first arc cover 23 and the second arc cover 24 are rotatably connected to each other, and a fixing mechanism 3 is arranged between the first arc cover 23 and the second arc cover 24 for positioning the first arc cover 23 relative to the second arc cover 24.

[0030] The present invention, by providing a sealing collar 21 and a clamping plate 22 for pressing the sealing collar 21, can adjust the distance between the first pipe joint 11 and the second pipe joint 12 by rotating the first pipe joint 11 or the second pipe joint 12 during use, thereby facilitating the connection of the two broken ends of the drainage pipe. During connection, the first pipe joint 11 and the second pipe joint 12 respectively connect the two broken ends of the drainage pipe by means of a socket. After connection, the two sealing collars 21 arranged outside the pipe joint body 1 are adjusted to move to the connection with the drainage pipe respectively, so that the connection can be simply sealed. Then, the two clamping plates 22 are adjusted to press outside the sealing collar 21 and the clamping plates 22 are adjusted to rotate to shorten the distance between the two clamping plates 22, so that the two clamping plates 22 clamp the sealing collar 21. After clamping, the first arc cover 23 is positioned relative to the second arc cover 24 by the fixing mechanism 3, thereby completing the fixing process of the position between the two clamping plates 22. During this period, the clamping plates 22 can continuously clamp the sealing collar 21, thereby increasing the sealing effect of the connection. After connecting two broken drainage pipes, the pipe joint is not prone to water seepage and has good practicality.

[0031] In one embodiment, a threaded ring 13 is fixed to the end of the first pipe joint 11, and a threaded groove 14 is formed at one end of the second pipe joint 12 corresponding to the threaded ring 13 and is threadedly connected to the threaded ring 13. With this design, when in use, the threaded ring 13 is threadedly connected to the threaded groove 14, and when the first pipe joint 11 or the second pipe joint 12 is rotated, the threaded ring 13 is rotated and moved relative to the threaded groove 14, thereby completing the distance adjustment between the first pipe joint 11 and the second pipe joint 12.

[0032] In one embodiment, a sealing ring 15 is disposed in the thread groove 14. This design is used to increase the sealing performance of the connection between the first pipe joint 11 and the second pipe joint 12.

[0033] In one embodiment, the fixing mechanism 3 includes a sealing plate 27 mounted on the first arc cover 23, a through rod hole 28 is opened on the sealing plate 27, a connecting rod 31 is movably inserted in the through rod hole 28, a third arc cover 32 is fixed on the cover wall of the first arc cover 23 and the second arc cover 24, the two third arc covers 32 are rotatably connected to each other and rotate coaxially with the first arc cover 23 and the second arc cover 24, a connecting frame 33 is slidably provided on the cover wall of the first arc cover 23 and the second arc cover 24, and is used to slide in a direction close to or away from the third arc cover 32, and the connecting frame 33 is connected to the first arc cover 23 or the third arc cover 24. A reset spring 37 is connected between the two arc-shaped covers 24, and a connecting column 39 is slidably connected to the end of the connecting frame 33; an annular groove 391 is provided on the connecting column 39 for sliding connection of the two connecting frames 33, a first toothed strip 392 is fixed on the connecting column 39, and a second toothed strip 393 is fixed on the third arc-shaped cover 32, the first toothed strip 392 can be engaged with the second toothed strip 393, and the connecting rod 31 is pressed against one end of the connecting column 39 to push the connecting column 39 to penetrate into or out of the two third arc-shaped covers 32; a positioning component is provided between the connecting rod 31 and the sealing plate 27 to position the connecting rod 31 relative to the sealing plate 27.

[0034] In a specific implementation, when in use, the connecting column 39 is inserted between the two third arc-shaped covers 32, and the first toothed strip 392 and the second toothed strip 393 are meshed. Under the mutual restriction of the first toothed strip 392 and the second toothed strip 393, the third arc-shaped cover 32 cannot rotate, and the distance between the two clamping clamps 22 is fixed. When it is necessary to adjust the rotation of the two clamping clamps 22 to clamp the sealing collar 21, the connecting rod 31 is inserted into the through rod hole 28 and pressed against the end of the connecting column 39, and the connecting rod 31 is continuously pushed. At this time, the connecting rod 31 pushes the connecting column 39 to gradually separate from the third arc-shaped cover 32, and the reset spring 37 is compressed. When the connecting rod 31 moves to the ideal position, the position of the connecting rod 31 relative to the sealing plate 27 can be positioned by the positioning component. At this time, the connecting column 39 is completely separated from the third arc-shaped cover 32, and the two third arc-shaped covers 32 can rotate relative to each other, so that the two clamping clamps 22 can rotate to compress the sealing collar 21. During the rotation, the second toothed strips 393 provided on the two third arc-shaped covers 32 may not affect the rotation of the third arc-shaped covers 32. After the clamping plate 22 clamps the sealing collar 21, the connecting rod 31 can be withdrawn, and the connecting column 39 is reinserted between the two third arc-shaped covers 32 under the action of the reset spring 37, and the first toothed strips 392 are meshed with the second toothed strips 393 again, thereby completing the distance fixation between the two clamping plates 22. This fixing method can only loosen the clamping plate 22 for rotation by inserting the connecting rod 31 into the through rod hole 28, and has high fixing stability. After long-term use, it still has a good fixing effect, and there is no need to frequently maintain the fixing part, which is convenient for use.

[0035] Preferably, a mounting inner plate 38 is fixed on the cover wall of the first arc-shaped cover 23 and the second arc-shaped cover 24 , and a return spring 37 is arranged between the mounting inner plate 38 and the connecting frame 33 .

[0036] In one embodiment, the positioning component includes a first clamping rod 35 disposed on the connecting rod 31 and a second clamping rod 36 disposed on the sealing plate 27 . The first clamping rod 35 can pass through the through rod hole 28 and rotate to be clamped with the second clamping rod 36 .

[0037] In the specific implementation, when the connecting rod 31 pushes the connecting column 39 out of the third arc cover 32, the first clamping rod 35 passes through the sealing plate 27 and is located on one side of the sealing plate 27. The rotation of the connecting rod 31 can be adjusted. The connecting rod 31 drives the first clamping rod 35 to rotate, and the first clamping rod 35 rotates to engage with the second clamping rod 36. At this time, the first clamping rod 35 is not easy to rotate under the action of the second clamping rod 36 and fits on one side of the sealing plate 27. Under the cover of the sealing plate 27, the first clamping rod 35 cannot be moved out, thereby completing the positioning processing of the connecting rod 31, facilitating the continuous push-out of the connecting column 39, and facilitating the adjustment of the rotation of the two clamping clamps 22.

[0038] In one embodiment, there are two sealing plates 27, which are respectively disposed at both ends of the first arc-shaped cover 23, and the sealing plates 27 are sealed and matched with the second arc-shaped cover 24. With such a design, when in use, the sealing plates 27 are located at both ends of the first arc-shaped cover 23 and are sealed and matched with the second arc-shaped cover 24, which can block foreign substances and prevent foreign substances from interfering with the use of various components in the first arc-shaped cover 23.

[0039] In one embodiment, a control rotating rod 34 is fixed to the end of the connecting rod 31. This design facilitates the adjustment of the position of the connecting rod 31 and the rotation of the connecting rod 31.

[0040] In one embodiment, the second clamping rod 36 is an elastic rubber rod, and a clamping slot for the second clamping rod 36 to be inserted is provided on the first clamping rod 35. In this design, by setting the second clamping rod 36 as an elastic rubber rod, when connecting the first clamping rod 35, the second clamping rod 36 can be deformed under the action of its own elastic force to be inserted into the clamping slot, which facilitates the clamping of the second clamping rod 36.

[0041] In one embodiment, a clamping bolt 26 is movably connected between the two clamping clamps 22. With this design, when the two clamping clamps 22 are pressed on the sealing collar 21, in order to make it easier for the clamping clamps 22 to press the sealing collar 21, the distance between the two clamping clamps 22 can be adjusted by rotating the clamping bolt 26, and the sealing collar 21 can be quickly pressed. At the same time, it is convenient to position the distance between the two clamping clamps 22 through the fixing mechanism 3.

[0042] Preferably, the two clamping clamps 22 are both fixed with mounting side plates 25 , and the clamping bolts 26 pass through the mounting side plates 25 for connection.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
