The guide block 7 is slidably connected inside the guide groove 8. By designing the guide groove 8, the guide block 7 can slide inside the guide groove 8. An elastic column 10 is fixedly connected to the outside of the slide block 6. The elastic column 10 is fixedly connected to the flange 2. A first spring 11 is provided on the outside of the elastic column 10. One end of the first spring 11 is fixedly connected to the slide block 6, and the other end of the first spring 11 is fixedly connected to the flange 2. By designing the first spring 11, the force of the first spring 11 can act on the slide block 6. A limit mechanism 9 is provided on the slide block 6.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The limiting mechanism 9 includes a fixed seat 91, which is fixedly connected inside the flange 2. The fixed seat 91 is slidably connected to the slide block 6. A pull rod 92 is slidably sleeved inside the fixed seat 91. A slide rod 93 is fixedly connected to the outside of the pull rod 92 and is slidably connected to the fixed seat 91. An insert block 94 is fixedly connected to the outside of the slide rod 93.

[0024] The specific implementation process of this utility model is as follows: In use, through the action of flange 2, flange 2 can be used for the connection and installation of composite steel pipes. Through the rotational connection between flange 2 and ceramic-lined composite steel pipe body 1, flange 2 can rotate. During the flange 2 docking installation process, there is no need to rotate ceramic-lined composite steel pipe body 1, making docking installation more convenient. When flange 2 is rotated, flange 2 will drive ball 5 to rotate. Ball 5 will roll along the arc surface of groove 4. Ball 5 will drive slide 6 to move, and slide 6 will drive guide... Block 7 slides along guide groove 8, while slide block 6 squeezes elastic column 10 and first spring 11 respectively, which can separate ball 5 from groove 4. As flange 2 rotates along ceramic-lined composite steel pipe body 1, under the elastic action of elastic column 10 and first spring 11, it will give slide block 6 a counter-push force, which can push ball 5 into groove 4 in another position. Through the insertion of ball 5 and groove 4, the relative position of flange 2 and ceramic-lined composite steel pipe body 1 can be fixed, which can prevent flange 2 from rotating randomly to a certain extent and improve the stability during docking.

[0025] After flange 2 is connected, push pull rod 92 into fixed seat 91. Pull rod 92 drives slide rod 93 and magnetic block 96 to move, causing magnetic block 96 to separate from magnet 97. At this time, under the elastic action of compressed second spring 99, slide rod 93 will have a reaction force, which can push slide rod 93 to move horizontally. Slide rod 93 will drive insert block 94 to move, so that insert block 94 is inserted into slide seat 6. At this time, slide seat 6 can be limited, and ball 5 can be locked, which can prevent ball 5 from separating from groove 4 and achieve the purpose of limiting flange 2. After steel pipe connection is completed, flange 2 can be prevented from rotating, improving the stability of flange 2 after connection.
