Figure 2 As shown, the fixing member 21 is a sleeve structure, which is rotatably mounted on the second pipe 20 to fix the relative position between the first flange member 101 and the second flange member 201 to lock the first pipe 10 and the second pipe 20 to improve sealing and convenience.

[0031] Further, in some implementations of this embodiment, Figures 3 to 5 As shown, the pipe fitting further includes a gasket 30. The gasket 30 is installed between the first pipe 10 and the second pipe 20.

[0032] In this embodiment, if Figure 3 As shown, the gasket 30 is installed between the connected first pipe 10 and the second pipe 20 to improve the sealing performance of the pipes in the connection, thereby improving the reliability of the device.

[0033] Further, in some implementations of this embodiment, Figure 4 As shown, the pipe fitting further includes: a mounting ring 102 and a plurality of positioning columns 103. The mounting ring 102 is mounted on the first pipe 10, and the first flange 101 is mounted outside the mounting ring 102 and the first pipe 10; the plurality of positioning columns 103 are distributed on the first flange 101 at intervals.

[0034] In this embodiment, if Figure 4 As shown, the mounting ring 102 contacts and positions the gasket 30 to prevent the gasket 30 from slipping during the installation process. There are six positioning posts 103, which are installed in groups of three on both sides of the first flange 101 and are symmetrically distributed to improve the stability of the installation and the reliability of the positioning, reduce the use of tools to assist in alignment, and improve the installation accuracy.

[0035] Further, in some implementations of this embodiment, Figure 4 and Figure 5 As shown, the second pipe 20 is provided with a plurality of positioning holes 202 corresponding to the plurality of positioning posts 103 , and the first pipe 10 moves toward the second pipe 20 , and the plurality of positioning posts 103 are slidably installed in the plurality of positioning holes 202 in a one-to-one correspondence.

[0037] Further, in some implementations of this embodiment, Figures 3 to 5 As shown, the gasket 30 is respectively covered on the circumferential sides of the mounting ring 102 and the second pipe 20 , and the end surface of the gasket 30 is abutted against the end surface of the mounting ring 102 and the second pipe 20 .

[0038] In this embodiment, if Figure 3 and Figure 5 As shown, the cross section of the gasket 30 is convex, and the positioning accuracy is improved by abutting against the mounting ring 102 and the peripheral side of the second pipe 20. The gasket 30 is covered on the first pipe 10 and the second pipe 20 at the connection to improve the strength of the connection, thereby improving the overall stability and reliability.

[0040] In this embodiment, if Figure 4 As shown, there are specifically two mounting blocks 104, and both have an arc-shaped surface, which are buckled with the second flange 201 to form a complete ring, thereby improving the overall strength, limiting the deviation of the central axis of the first pipe 10 relative to the central axis of the second pipe 20, reducing the lateral force of the positioning column 103, and improving the strength of the connection, thereby improving the stability of positioning and installation.

[0044] In this embodiment, if Figure 4 As shown, the gasket 30 has an outer fixing layer and an inner sealing layer. The mounting ring 102 and the end face of the second pipe 20 are respectively abutted against both sides of the sealing layer. By providing a groove, the gasket 30 can release stress into the groove when subjected to pressure, thereby improving the service life and installation strength.

The positioning column 103 is positioned to improve positioning accuracy, thereby reducing the installation gap, reducing the operating steps of auxiliary alignment to improve installation efficiency, and the flange is positioned and locked to reduce the installation gap, thereby improving the sealing and the smoothness of water flow at the connection.
