[0009] Furthermore, the left and right parts of the external fixed frame structure are provided with a plurality of groups of positioning holes, and each group of positioning holes is sleeved outside a corresponding group of positioning heads on the same side.

[0010] Furthermore, two groups of outer pads are provided at the upper and lower parts of the outer fixed frame structure, and screw holes are opened in the outer pads, and fastening bolts are installed in the screw holes.

[0011] The beneficial effects of the utility model are:

[0012] 1. The positioning head provided on the side fixing plate in the utility model is for accurate positioning, so that the positioning holes on the left and right parts of the external fixed frame structure can be inserted into the corresponding holes, so that the protective structure can be inserted into the sleeve frame from the rear side of the external fixed frame structure. At this time, the side fixing plate is pressed on the rear side of the protective structure, so that the assembly between the protective structure and the external fixed frame structure is accurate, stable and reliable.

[0013] 2. The inner pad on the rear side of the middle side fixing plate and the outer pad on the rear side of the protective structure of the utility model are both made of silicone rubber, which has a damping effect, so that the protective structure is covered outside the fire alarm and fixed on the wall, which is safe and non-slip.

[0014] 3. In the utility model, the explosion-proof cover is covered outside the speaker of the alarm, and the transparent cover is covered outside the flash light of the alarm, so the protection is more complete and firm, avoiding external collision.

[0015] 4. The utility model fixes the external fixed frame structure on the wall by installing fastening bolts in the outer pads of the upper and lower parts of the external fixed frame structure, so that the installation is convenient and stable. BRIEF DESCRIPTION OF THE DRAWINGS
