[0026] Working principle:

[0027] Using the Install Phase

[0028] The connecting seat 6 at the lower end of the base 5 is fixed to the external installation position, and the anti-skid pad 7 with concave and convex rubber material at the lower end of the connecting seat 6 has a buffering and anti-skid effect to ensure the stability of the upper base 5.

The equipment can be installed on the mounting seat 306 on the surface of the mounting plate 305 as needed. Finally, the door panel 8 is closed so that the limiting rod 402 on the connecting block 403 of the outer wall of the door panel 5 is sleeved on the card block 401. The external lock or the like passes through the hole 9 to limit the separation of the limiting rod 402 and the card block 401 to ensure that the door panel 8 and the shell 1 are firmly closed.

[0029] Use explosion-proof stage

[0030] First, air flows through the larger holes 9 on the surface of the top plate 2 to the installation box 10, and the filter 11 on the installation box 10 intercepts foreign matter to prevent foreign matter from entering the interior of the shell 1, thereby ensuring the cleanliness of the interior. At the same time, the temperature sensor 12 and the smoke alarm 13 detect the temperature and smoke inside the shell 1, and the warning light 14 warns of danger to ensure that the interior is in an installed state and achieve an explosion-proof effect. When an internal explosion occurs, the shell 1 and the door panel 8 are fixed with the first reinforcing rod 302 and the second reinforcing rod 303, so that when the whole is broken into pieces, the first reinforcing rod 302 and the second reinforcing rod 303 can pull them to avoid the explosion airflow from promoting the fragments to come into contact with people, thereby ensuring the best installation effect during use.
