[0018] 3. This kind of linked self-locking explosion-proof control cabinet squeezes the inert gas in the second partition through the first connecting rod and the lifting plate to speed up its discharge. Sand and the first sealing plate fall onto the squeezing plate to squeeze the airbag, so that the inert gas in the airbag enters the second partition and is then discharged, further improving the fire extinguishing efficiency and ensuring that the fire can be extinguished quickly and thoroughly.

[0019] 4. This linkage self-locking explosion-proof control cabinet, through the cooperation between the first magnet block and the second magnet block, after the placement plate falls and is fixed, it is tightly fixed, and the second sealing plate at the bottom of the placement plate then blocks the heat dissipation net, effectively preventing the external flammable and explosive gas from entering the cabinet through the heat dissipation hole. This can prevent the external gas from contacting the fire source inside the cabinet, avoid the fire from increasing due to gas combustion, eliminate potential dangers from the source, and ensure the safety of the cabinet and the surrounding environment.

[0020] 5. This kind of linkage self-locking explosion-proof control cabinet, through the design of the card block, threaded rod and hinge block, when the placement plate is flipped, the card block is inserted into the card gap formed by the threaded rod and the hinge block to lock the cabinet door, so as to avoid the influx of flammable and explosive gases from the outside due to accidental opening of the cabinet door when a fire occurs, causing the fire to worsen. After the fire is extinguished, the threaded rod and the hinge block are separated by turning the knob, and the cabinet door can be opened for cleaning, which provides a safe and stable environment for the equipment inside the cabinet and prevents secondary accidents.
