The end of the lower fixing sleeve 2 away from the hinge is fixedly connected to the second connecting frame 4. Multiple sealing gaskets 5 are located between the upper fixing sleeve 1 and the lower fixing sleeve 2. The ends of the multiple sealing gaskets 5 that are far apart from each other are fixedly connected to the inner walls of the ends of the upper fixing sleeve 1 and the lower fixing sleeve 2 that are close to each other. The upper fixing sleeve 1 and the lower fixing sleeve 2 are connected to the leak in the heating pipe. The fixing mechanism fixes the lower fixing sleeve 2 and the upper fixing sleeve 1 to the heating pipe, thereby making the sealing gaskets 5 fit against the leak in the heating pipe. The sealing gaskets 5 temporarily seal the leak in the heating pipe to facilitate subsequent maintenance. In embodiment two, the present invention provides a fixing mechanism, which is applied to a heating pipe network leak prevention device in embodiment one. The fixing mechanism is located on one side of the upper fixing sleeve 1 and the lower fixing sleeve 2. The fixing mechanism includes an installation part and a fixing part. The installation part is rotatably inserted and connected to the end of the second connecting frame 4 away from the lower fixing sleeve 2. The fixing part is slidably inserted and connected to the top of the installation part. The fixing part is used to fix the upper fixing sleeve 1 and the lower fixing sleeve 2.

[0020] Specifically, the installation department includes: Rotating rod 13 is disposed inside the second connecting frame 4, and both ends of rotating rod 13 are rotatably inserted and connected to the inner wall of the end of the second connecting frame 4 away from the lower fixed sleeve 2. Mounting bracket 12, one end of which is sleeved with the middle of rotating rod 13, and the other end of mounting bracket 12 away from rotating rod 13 is threadedly connected to the fixing part; Specifically, the fixing part includes: Threaded rod 11, one end of threaded rod 11 is threadedly connected to the end of mounting bracket 12 away from rotating rod 13; The fixing plate 6 is fixedly connected at one end to the end of the threaded rod 11 away from the mounting bracket 12, and the bottom of the fixing plate 6 is attached to the top of the first connecting bracket 3. Connecting rod 7, one end of which is fixedly connected to the end of fixing plate 6 away from threaded rod 11; Pull rod 8 is inserted and connected to the end of connecting rod 7 away from fixed plate 6; It should be noted that the rotating rod 13 is installed inside the second connecting frame 4. Both ends of the rotating rod 13 are rotatably connected to the inner wall of the second connecting frame 4 at the end furthest from the lower fixed sleeve 2. The outer wall of the rotating rod 13 is sleeved on one end of the mounting frame 12. The end of the mounting frame 12 furthest from the rotating rod 13 is threadedly connected to the threaded rod 11. The end of the threaded rod 11 furthest from the mounting frame 12 is fixedly connected to the fixing plate 6. The end of the fixing plate 6 furthest from the threaded rod 11 is fixedly connected to the connecting rod 7. The end of the connecting rod 7 furthest from the fixing plate 6 is threadedly connected to the pull rod 8. The upper fixed sleeve 1 and the lower fixed sleeve 2 are connected to the leak in the heating pipe. The movement of the rotating frame drives the threaded rod 11 to move, and the movement of the threaded rod 11 drives... The fixed plate 6 moves to the top of the first fixed frame. The pull rod 8 is rotated, which drives the connecting rod 7 to rotate. The connecting rod 7 then drives the fixed plate 6 to rotate, which in turn drives the threaded rod 11 to rotate. The threaded rod 11 is then threadedly connected to the mounting bracket 12. The movement of the threaded rod 11 causes the fixed plate 6 to press down on the first fixed frame, bringing the first fixed frame closer to the second fixed frame. The cooperation between the first and second fixed frames then fixes the lower fixed sleeve 2 and the upper fixed sleeve 1 to the heating pipe. The sealing gasket 5 temporarily seals any leaks in the heating pipe, allowing for quick fixation of the leak-proof device to the heating pipe and improving maintenance efficiency. A limiting groove is provided at the end of the first connecting frame 3 away from the upper fixed sleeve 1. A limiting rod 10 is slidably inserted into the limiting groove. One end of the limiting rod 10 passes through the limiting groove and is slidably inserted into the side of the first fixed frame away from the limiting groove. A push rod 9 is fixedly installed on the side of the limiting rod 10 away from the upper fixed sleeve 1. The end of the push rod 9 away from the limiting rod 10 passes through the limiting groove. Furthermore, a limiting spring 14 is provided in the limiting groove. One end of the limiting spring 14 is fixedly connected to the inner wall of the limiting groove, and the other end of the limiting spring 14 is fixedly connected to the end of the limiting rod 10 near the push rod 9. It should be noted that one end of the limiting rod 10 is inserted into the limiting groove, and the end of the limiting rod 10 away from the limiting groove is slidably inserted into the side of the first fixed frame away from the limiting groove. The end of the limiting rod 10 away from the upper fixed sleeve 1 is fixedly connected to the push rod 9, and the end of the push rod 9 away from the limiting rod 10 extends out of the limiting groove. The limiting spring 14 is set in the limiting groove, one end of the limiting spring 14 is fixedly connected to the inner wall of the limiting groove, and the other end of the limiting spring 14 is fixedly connected to the end of the limiting rod 10 near the push rod 9. The upper fixed sleeve 1 and the lower fixed sleeve 2 are connected to the leak in the heating pipe. Pushing the push rod 9 moves the limiting rod 10, causing it to move into the limiting groove. The rotating frame moves the threaded rod 11, which in turn moves the fixed plate 6, moving it to the top of the first fixed frame. The pull rod 8 is then rotated. The rotation of the pull rod 8 drives the connecting rod 7 to rotate, which in turn drives the fixing plate 6 to rotate. The rotation of the fixing plate 6 drives the threaded rod 11 to rotate, causing the threaded rod 11 to be threadedly connected to the mounting bracket 12. The movement of the threaded rod 11 causes the fixing plate 6 to press down on the first fixing bracket, bringing the first fixing bracket closer to the second fixing bracket. The cooperation between the first and second fixing brackets then fixes the lower fixing sleeve 2 and the upper fixing sleeve 1 to the heating pipe. The sealing gasket 5 temporarily seals any leaks in the heating pipe. The push rod 9 is released, and the spring force of the limiting spring 14 pushes the limiting rod 10 to move, causing one end of the limiting rod 10 to pass through the limiting groove and slide and connect with the side of the first fixing bracket away from the limiting groove. The limiting rod 10 restricts the position of the mounting bracket 12, preventing the upper fixing sleeve 1 and the lower fixing sleeve 2 from loosening due to the movement of the mounting bracket 12, thus improving stability.
