[0036] Reference Figure 4 , Figure 5The connecting sleeve 15 is arranged in the pipeline 4, and the connecting sleeve 15 can push the sealing block 11 to move when being inserted into the pipeline 4. A plurality of perforations are arranged in the right end of the connecting sleeve 15, and the medium can flow into the pipeline 4 through the plurality of perforations. The pipeline 4 is fixedly connected with the mounting plate 12, and the mounting plate 12 is used for mounting the spring 13. The mounting plate 12 is fixedly connected with the spring 13 on the left side. The spring 13 is fixedly connected with the sealing block 11 on the left end. The spring 13 is used for pushing the sealing block 11 to seal the pipeline 4. The right end of the connecting sleeve 15 is abutted on the left side of the sealing block 11. The pipeline 4 is fixedly connected with the sealing ring 14, and the sealing ring 14 is arranged on the left side of the sealing block 11. The sealing ring 14 is used for enhancing the sealing performance of the sealing block 11.

[0037] With reference to Figure 1 , Figure 6 and Figure 7 , the pipeline 1 and the pipeline 4 are each provided with a protection assembly. The protection assembly is used for protecting the pipeline 1 and the pipeline 4. The two protection assemblies each include a protection shell 25. The two protection shells 25 are respectively abutted on the outer periphery of the pipeline 1 and the pipeline 4. The protection shell 25 is used for protecting the pipeline 1 and the pipeline 4. The protection shell 25 is fixedly connected with a support plate 1, a support plate 2 and a fixed plate 16 on the outer periphery. The support plate 1 and the support plate 2 are used for mounting a support shaft 20. The fixed plate 16 is used for mounting a hanging ear 22. The support plate 1 and the support plate 2 are fixedly connected with the support shaft 20 on the opposite side. The support shaft 20 is used for supporting a moving block 24 to move. The support shaft 20 is slidingly connected with the moving block 24 on the outer periphery. The moving block 24 can drive a connecting frame 23 to move. The support shaft 20 is sleeved with a tension spring 17 on the outer periphery. One end of the tension spring 17 is fixedly connected with the moving block 24 on the top side. The other end of the tension spring 17 is fixedly connected with the support plate 1 on the bottom side. The tension spring 17 is used for pulling the moving block 24 to reset. The moving block 24 is fixedly connected with two fixed sleeves 21 on the outer periphery. The fixed sleeves 21 are used for mounting the connecting frame 23. The connecting frame 23 is rotatably connected with the fixed sleeves 21 in the two fixed sleeves 21. The fixed plate 16 is fixedly connected with the hanging ear 22 on the bottom side. The connecting frame 23 is abutted on the inner side of the hanging ear 22. The connecting frame 23 and the hanging ear 22 are connected with each other to enable the protection shell 25 to be closed. The support plate 2 is rotatably connected with a rotating rod 19 on the outer periphery. The two fixed sleeves 21 are slidingly connected with the rotating rod 19 on the inner side of the left side and the right side. The rotating rod 19 is pushed to rotate to enable the connecting frame 23 to be separated from the hanging ear 22.

[0038] Working principle: when laying the heat preservation pipe, the pipe one 1 and the pipe two 4 are contacted at the opposite end, then the fixed frame 5 is installed outside the opposite end of the pipe one 1 and the pipe two 4, the fixed frame 5 can wrap the opposite end of the pipe one 1 and the pipe two 4 to connect the opposite end of the pipe one 1 and the pipe two 4. Rotating the fixed frame 5 makes the connecting plate 6 inserted into the inside of the installation block two 3, the moving shaft 7 in the inside of the installation block two 3 can be pushed into the inside of the connecting plate 6 by the spring one 9 to fix the connecting plate 6 in the inside of the installation block two 3, thus the pipe one 1 and the pipe two 4 are connected. When the pipe one 1 and the pipe two 4 are connected, the connecting sleeve 15 can be inserted into the inside of the pipe two 4 and push the sealing block 11 to move to the inside of the pipe two 4, when the sealing block 11 is separated from the sealing ring 14, the medium in the inside of the pipe one 1 can flow into the inside of the pipe two 4 through the multiple perforations in the inside of the connecting sleeve 15.

[0039] After the pipe one 1 and the pipe two 4 are connected, the protective shell 25 can be installed outside the pipe one 1 and the pipe two 4, after the pipe one 1 and the pipe two 4 are wrapped by the protective shell 25, the connecting frame 23 can be pulled to move to the hanger ear 22, during the moving process of the connecting frame 23, the moving block 24 can stretch the tension spring 17, when the connecting frame 23 and the hanger ear 22 are connected, the tension spring 17 can contract to fix the connecting frame 23 in the inside of the hanger ear 22, thus the protective shell 25 is closed and fixed outside the pipe one 1 and the pipe two 4. The rotating rod 19 is pushed to rotate and drive the moving block 24 to move to the support plate two 27, the moving block 24 can drive the connecting frame 23 to move to separate the connecting frame 23 from the hanger ear 22, then the connecting frame 23 and the hanger ear 22 can be separated and the protective shell 25 is opened, after the protective shell 25 is opened, the protective shell 25 can be taken off.

[0040] When the pipe one 1 or the pipe two 4 needs to be maintained, the moving shaft 7 can be pulled out from the inside of the connecting plate 6 by pulling the pull ring 10, then the fixed frame 5 can be opened to take out the end of the pipe one 1 or the pipe two 4, thus the pipe one 1 and the pipe two 4 are quickly separated, which is convenient for the quick maintenance of the pipe one 1 and the pipe two 4. After the pipe one 1 and the pipe two 4 are separated, the connecting sleeve 15 is taken out from the inside of the pipe two 4, the sealing block 11 can be pushed to contact the sealing ring 14 by the spring two 13 to seal the pipe two 4, thus the medium in the inside of the pipe two 4 is prevented from leaking.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application and does not limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solution recorded in the foregoing embodiments, or equivalent replacement of some of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
