One ends of the two groups of fixing rods 403 respectively movably penetrate through the upper cover body 2 to the interiors of the two embedded grooves 3. One ends of the two groups of fixing rods 403 are fixedly installed with pressing plates 402. Power springs 404 are movably sleeved on the outer surfaces of the two groups of fixing rods 403 near the pressing plates 402.

[0030] Working principle: When in use, the four positioning rods 6 are aligned and inserted into the four positioning slots 10, so as to install the upper cover body 2 on the top of the outer shell body 1. Through the cooperation of the positioning rods 6 and the positioning slots 10, a positioning effect is achieved to realize the pre-installation of the upper cover body 2. Then, the bolts 9 are screwed into the corresponding threaded holes 8 and the threaded grooves 7, and the positioning rods 6 are fixed by the bolts 9, thereby fixing the upper cover body 2. At this time, the sealing sleeve 504 is inserted into the inner part of the outer shell body 1 and fits with the inner wall of the outer shell body 1, and the second sealing ring 503 fits with the top of the outer shell body 1. Through the cooperation of the first sealing ring 502, the sealing plate 501 and the second sealing ring 503, the space between the upper cover body 2 and the outer shell body 1 is sealed. At the same time, the sealing sleeve 504 fits with the inner wall of the outer shell body 1 to enhance the sealing effect. Under the action of the sealing assembly 5, a sealing effect is achieved to prevent moisture or fine dust in the air from entering the interior through the gap between the upper cover body 2 and the outer shell body 1, and to avoid the influence of moisture on the internal circuit components. When in use, the upper cover body 2 is removed from the outer shell body 1, and then the two pressing plates 402 are pressed in opposite directions. When the external thrust causes the pressing plates 402 to move into the inner groove 3, the corresponding strong springs 404 will be compressed and contracted. At the same time, multiple fixing rods 403 will be pushed to move, and then two fixing plates 401 will be pushed to slide inside the two L-shaped connecting plates 505, further driving multiple locking rods 405 to move out of the card slots 12 and the card holes 506. At this time, both of the two L-shaped connecting plates 505 lose their limits. Then, the sealing assembly 5 is pulled downward so that it slides off the outer surfaces of the multiple positioning rods 6, and the sealing assembly 5 can be disassembled from the bottom of the upper cover body 2, which is convenient for replacing a new sealing assembly 5.
