[0067] Working principle: When the device is used, the sensor guide tube 3 is first sleeved in the first mounting groove 2 so that the limiting plate contacts the lower surface of the box wall panel 1, and then the two connecting blocks 17 are pulled in opposite directions, so that the two connecting blocks 17 drive the two fixing blocks 15 to move out of the two positioning grooves 8 during the movement. At this time, the two springs 16 are stretched, and the mounting block 5 is then sleeved downward on the sensor guide tube 3 through the third mounting groove 13 until the mounting block 5 squeezes the sealing gasket 12. At this time, the pulling of the two connecting blocks 17 is released, and the two fixing blocks 15 are driven to move into the two positioning grooves 8 under the action of the released elastic force of the spring 16, thereby fixing the sensor guide tube 3 and the mounting block 5. When disassembling, you only need to pull the two connecting blocks 17 to release the fixation, which is convenient for fixing and disassembly, thereby increasing the practicality of the sensor position adjustment device and improving the installation and disassembly efficiency of the sensor position adjustment device.

When it is necessary to adjust the depth of the measuring rod component of the temperature sensor 6 extending into the box body, it is only necessary to loosen the fixing bolt 11 to release the temperature sensor 6. At this time, by pulling out the temperature sensor 6, the depth of the temperature sensor 6 extending into the box body can be adjusted, and then the depth of the cold end extending into the box body can also be adjusted.
