An L-shaped card slot 2 is opened on the inner wall of the base 1. A fire-resistant reinforcement housing 5 is inserted into the base 1, and a card block 6 is arranged on the surface of the fire-resistant reinforcement housing 5. The card block 6 and the L-shaped card slot 2 are clamped to fix the base 1 and the fire-resistant reinforcement housing 5. More specifically, the fire-fighting electrical body 3 is fixedly installed inside the base 1 through the fixing bolt 4. When protecting the fire-fighting electrical body 3, the card block 6 on the surface of the fire-resistant reinforcement housing 5 is inserted into the opening of the L-shaped card slot 2 on the inner wall of the base 1, and the fire-resistant reinforcement housing 5 is rotated to drive the card block 6 to be clamped to the clamping location of the L-shaped card slot 2, thereby realizing the assembly surface of the base 1 and the fire-resistant reinforcement housing 5. The fire-fighting electrical body 3 inside is protected by the base 1 and the fire-resistant reinforcement housing 5, and the base 1 and the fire-resistant reinforcement housing 5 can be disassembled conveniently through the L-shaped card slot 2 and the card block 6, so that it can be disassembled flexibly, facilitating the maintenance and replacement of the equipment.
[0026] The base 1 includes a bottom shell 101. An installation convex block 102 is fixedly installed on the surface of the bottom shell 101, and an internal thread ring 103 is fixedly installed on the inner top of the bottom shell 101.

More specifically, the installation holes on the surface of the fire-fighting electrical body 3 correspond to the internal thread ring 103, so that the fire-fighting electrical body 3 can be fixed through the fixing bolt 4.
[0028] The fire-resistant reinforcement housing 5 includes an installation ring 501.
