In implementation, the distance sensor 32 is arranged at the edge of the cover 18 away from the fixed side, and the distance sensor 32 detects the gap distance of the cover 18. When the distance is greater than 0.5 cm, the sensor issues a warning.

[0070] In actual use, the user adjusts the position of the partition 15 according to the size and temperature requirements of the two groups of articles to be stored. The partition 15 is fixed in the appropriate position by the sliding groove 13 and the buckle 14 of the inner box body long edge, thereby dividing the inner box body into two independent spaces, ensuring that the two groups of articles do not affect each other. The cold source is placed in the compartment outside the inner box body 12 of the insulation box to maintain the required low temperature environment. Then the first group of articles is placed in one side space and the second group of articles is placed in the other side space, ensuring that the articles do not directly contact the box wall. The built-in temperature sensor 16 is started to monitor the temperature in the box in real time, ensuring that the articles are kept within the appropriate temperature range. After confirming that the sealing edge inside the box cover 18 completely matches the inner box body, the box cover 18 is closed and fixed using the lock buckle 31 to ensure safety during transportation. Through the universal wheels 21 at the bottom, the insulation box can be easily moved to the desired position, and if it needs to be fixed, the direction lock 22 can be used. If quick access to the articles is required, the double-sided opening and closing push-pull door 17 at the top of the inner box body can be used. Finally, the alarm 33 and distance sensor 32 in the safety mechanism monitor the opening and closing state of the box cover 18, and if the gap of the box cover 18 is greater than 0.5 cm, the alarm 33 will issue a warning.
