After the rotating tube 41 moves to the specified position, the push block 12 is released. Under the elastic force of the second spring 13, the positioning rod 11 can move, thereby The positioning rod 11 can limit the position of the rotating tube 41, so that the rotating tube 41 can remain stable and prevent it from escaping from the inside of the groove 3. At the same time, the micro fan 17 can be started. Under the action of the micro fan 17, the outside air can be extracted through the air inlet window 16, and then the air is transported through the connecting pipe 18, so that the air can continuously flow inside the groove 3, so that dust will not adhere to the outside of the insulating sleeve 10, and when the staff opens the sealing door 2 through the rotating tube 41, the air will not enter the inside of the distribution cabinet body 1.

[0033] Working principle: When using the device, the staff first installs the device, puts the rotating tube 41, the insertion rod 7 and the adjusting rod 44 into the groove 3, and then adjusts the position of the adjusting rod 44 according to the size of the rotating shaft 9, rotates the rotating tube 41, and under the action of the rotating tube 41, drives the adjusting rod 44 to move, and then under the action of the adjusting rod 44, the insertion rod 7 can be driven to move, so that the insertion rod 7 enters the inside of the rotating shaft 9, and then when the rotating tube 41 is pulled, the rotating shaft 9 can be driven to rotate inside the connecting block 8, and then the push block 12 is pushed, and the push block 12 drives the positioning rod 11 to move, so that the second spring 13 is compressed. After the positioning rod 11 moves to the specified position, the staff pushes the rotating tube 41 so that the rotating tube 41 can squeeze the block 42. When the block 42 moves, it can drive the connecting rod 43 to move, so that the first spring 5 can be compressed. When the rotating tube 41 moves to the specified position, the push block 12 is released. Under the elastic force of the second spring 13, the positioning rod 11 can move, so that the positioning rod 11 can pass through the positioning hole inside the rotating tube 41 to limit the position of the rotating tube 41, so that the rotating tube 41 can remain stable and prevent it from escaping from the inside of the groove 3. At the same time, the micro fan 17 is started. Under the action of the micro fan 17, the outside air can be extracted through the air inlet window 16, and then the air is transported through the connecting pipe 18, so that the air is ejected at the air outlet pipe 19, so that the air can flow inside the groove 3, so that dust will not adhere to the outside of the insulating sleeve 10.
