[0033] Everything in the above example works like this:

[0034] When in use, first align the box body 1 with the rear shell 2, so that the hole on the box body 1 corresponds to the positioning block 22 on the rear shell 2 to avoid incorrect assembly between the two. At the same time, the first magnet 11 and the second magnet 12 that are staggered at the bottom of the installation groove 16 and the bottom of the protective ring 8 can further avoid incorrect assembly between the two, and then can remind the user of the installation direction, thereby reducing the difficulty of using the temperature control box; in addition, the first magnet 11 and the second magnet 12 that are set can also make the protective ring 8 and the installation groove 16 fit more closely, so as to a certain extent Prevent moisture from entering the box body 1 and damaging the electrical components therein; subsequently, the convex protection ring 8 fits with the sealing ring 7 provided inside the concave installation groove 16, making the two closer and effectively reducing the gap between the two, thereby improving the waterproof performance of the temperature control box. As the box body 1 and the rear shell 2 are buckled together, the protection ring 9 on the box body 1 fits tightly against the outer surface of the rear shell 2, thereby achieving a multi-level waterproof effect, which can further increase the waterproof performance of the temperature control box and effectively prevent moisture from entering the box, causing The two adjusting heads 18 are then manually pulled to cause the two limiting rods 17 to slide relative to each other along the connecting rod 19, and the limiting spring 20 is continuously squeezed to shrink.
