[0002] Refrigerated trucks refer to closed van transport trucks used to maintain the temperature of frozen or fresh goods. They can be classified by manufacturer, chassis carrying capacity, and compartment type. There are mechanical refrigerated trucks, cold plate refrigerated trucks, liquid nitrogen refrigerated trucks, and dry ice refrigerated trucks, among which mechanical refrigerated trucks are the main ones. Their refrigeration system consists of a compressor expansion valve and an evaporator, and the working principle is steam compression refrigeration. Refrigerated trucks are often used to transport frozen foods, dairy products, vegetables and fruits, vaccines and medicines, so that the health quality of various foods can be maintained.

[0024] Specifically, the mounting base 3 is inserted into the mounting base 3, and the laid electrical connection is connected to the mounting base 3, so that the temperature sensor 10 and the humidity sensor 11 are powered on, so that the temperature sensor 10 and the humidity sensor 11 can work normally.

[0025] Preferably, the pressing plate 8 is slidably connected to the side groove 4 , two ends of the spring 7 are connected to the surface of the pressing plate 8 and the surface of the fixing plate 5 , and limiting holes are provided on both sides of the mounting seat 3 .

[0026] Specifically, the limiting block 9 can be tightly clamped into the limiting hole under the pressure of the spring 7 to fix the installation of the mounting seat 3.

[0029] Working principle: The temperature and humidity inside the cold storage box 1 can be set in advance through the external PLC controller 13, and then the temperature sensor 10 and the humidity sensor 11 will monitor the internal temperature and humidity. When the temperature is detected to be higher than the set temperature, the PLC controller 13 controls the operation of the refrigerator 14 to increase the working power, so that the temperature is reduced. At the same time, when the temperature is lower than the set temperature, the PLC controller 13 controls the power of the refrigerator 14 to reduce the power, so that the temperature can be automatically adjusted according to the set temperature. Similarly, the temperature sensor 10 and the humidity sensor 11 are set inside and outside the cold storage box 1. In this way, the cold storage box 1 can be monitored more evenly and accurately. When the temperature sensor 10 and the humidity sensor 11 are maintained and replaced, the pull rods 6 on both sides are pulled, and the pull rods 6 will move with the pressure plate 8, and the pressure plate 8 will squeeze the spring 7, so that the limit block 9 leaves the limit hole, and then the mounting seat 3 can be removed. When installing, the pull rod 6 is also pulled, and then the mounting seat 3 is inserted into the installation groove, and then the pull rod 6 is released. Under the compression of the spring 7, the limit block 9 is inserted into the limit hole to fix the mounting seat 3, so that the temperature sensor 10 and the humidity sensor 11 can be easily installed and disassembled, which is convenient for the staff to repair and replace.
