When the fire detector 2 detects flames, smoke or other signs of fire, the fire alarm sends a signal. An inspection cover 3 is installed on the front of the protective box 1 for inspecting and maintaining the components inside the protective box 1. A water absorbent plate 6 is installed below the fire alarm 2 on the protective box 1 for dehumidifying the air inside the protective box 1. The fixed frame 401 and the elastic rubber pad 502 are used to abut and seal to improve the air tightness and friction between the fixed frame 401 and the frame 5011 to prevent the fixed frame 401 from sliding at will. The damping strip 403 and the damping groove 5012 are used to fix the fixed frame 401 on the frame 5011. When disassembling, the fixed frame 401 can be separated by simply pulling the fixed frame 401, which has the effects of convenient disassembly and assembly and easy maintenance.

[0026] Reference Figure 2 An elastic rubber pad 502 is sleeved on the outer side of the frame 5011, and the elastic rubber pad 502 fits with the inner wall of the fixed frame 401. A plurality of guide inclined plates 504 are installed in the ventilation port, and a dustproof plate 503 is installed on the inner side of the frame 5011. The dustproof plate 503 is used for oblique flow guidance to reduce dust from reaching the frame 5011 through the ventilation port.

[0027] Reference Figure 4 The dustproof plate 503 includes several guide inclined plates 5031 installed in the installation frame 501, and a guide plate 5033 is installed on the side of the lowest guide inclined plate 5031, and the guide plate 5033 abuts against the lower wall of the ventilation port. Guide blocks 5032 are installed on the lower sides of other guide inclined plates 5031.
