[0027] As a further implementation of the present solution, the fire damper body 1 includes a main body shell 11, and a storage groove 12 is provided at the upper end and the lower end of one side of the main body shell 11, and the barrier mechanism 9 is installed inside the storage groove 12. The barrier mechanism 9 can be stably stored through the storage groove 12;
[0028] As a further implementation of this solution, the fixed housing 93 is welded and fixed to the side of the main housing 11, and the button cap 94 is arranged outside the fixed housing 93. The connecting shaft 92 is rotatably connected to the main housing 11. The fixed housing 93 can cooperate with the spring spring 95 to drive the high temperature resistant baffle plate 91 to block the main housing 11. At the same time, the button cap 94 is arranged to facilitate the reset of the fire damper as a whole.
[0029] As a further implementation of this solution, two blocking mechanisms 9 are provided, and the blocking mechanisms 9 are respectively arranged at the upper end and the lower end of the flap 8, and the flap 8 is installed inside the main housing 11. Through the above arrangement, the stability of the overall structure of the device is further improved;
[0030] As a further implementation of this solution, the first connecting flange 2 and the second connecting flange 6 are provided with connecting holes 5 at four corners, the edge of the connecting hole 5 is arc-shaped, and the first connecting flange 2 and the second connecting flange 6 are parallel, so that the fire damper as a whole can be stably connected to the external pipeline;
[0031] As a further implementation of the present invention, both sides of the moving frame 10 are fixedly connected to the limiting blocks 3, the moving frame 10 is slidably connected to the inside of the main housing 11 through the limiting blocks 3, the positioning bolts 4 are spirally connected to the main housing 11, and the top of the positioning bolts 4 is in close contact with the limiting blocks 3, so that the position of the moving frame 10 can be adjusted and its stability after the adjustment can be ensured;

After the flap 8 rotates, the high-temperature resistant barrier plate 91 will rotate driven by the clockwork spring 95, and further block the inside of the main shell 11 to form a double-layer barrier, which can improve the heat insulation effect. At the same time, such a setting can also prevent the problem of high temperature damaging the controller 7 caused by the spread of fire during actual application.
