[0019] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: Please refer to Figures 1-3 , a ventilation device for a radio and television engineering machine room, includes an installation frame 1, a fan fixing structure is installed inside the installation frame 1, and a shielding structure is provided on one side of the installation frame 1.

[0021] The fan fixing structure includes: eight fixed plates 2, a fan body 3, four insertion rods 4, a limiting ring 5, two connecting pieces 6, and two connecting bolts 7.

[0022] Eight fixing plates 2 are respectively installed at the octagonal corners inside the installation frame 1. The fan body 3 is embedded inside the installation frame 1. Four inserting rods 4 are respectively movably embedded inside the eight fixing plates 2 and at the four corners of the fan body 3. The four ends of the limiting ring 5 are connected to the four inserting rods 4. Two connecting pieces 6 are respectively installed on both sides inside the installation frame 1. Two connecting bolts 7 are respectively embedded on both sides of the limiting ring 5 and inside the two connecting pieces 6.

[0023] When installing the fan, the staff first fixes the installation frame 1 in the designated wall by pouring. Then, the fan body 3 is tilted and placed into the installation frame 1. After placing it, the fan body 3 is straightened. Subsequently, the four inserting rods 4 on one side of the limiting ring 5 are respectively embedded into the four corners of the fan body 3 and the eight fixing plates 2 to perform inserting and limiting on the fan body 3. Then, the connecting bolts 7 are embedded into both sides of the limiting ring 5 and inside the two connecting pieces 6 to fix the limiting ring 5, and thus the installation of the fan can be completed. During the ventilation process, through the operation of the fan inside the installation frame 1, the outside air is transported into the computer room to achieve the ventilation operation of the computer room.
