[0028] Specific application examples of the utility model:

[0029] The fire door is provided with ventilation by providing a through slot 11 on the door panel 1. The ventilation assembly 2 is arranged in the through slot 11, and the windshield 22 in the ventilation assembly 2 cooperates with the ventilation plate 21 to control the connection area of ​​the ventilation hole 23, thereby adjusting the ventilation effect of the through slot 11. The rotating assembly 3 is connected to the ventilation plate 21 through the rotating block 31, driving the windshield 22 connected to the rotating shaft 32 to rotate, controlling the windshield 22 to cover the ventilation hole 23 on the ventilation plate 21, and adjusting the ventilation performance by controlling the different exposed areas of the ventilation hole 23. One end of the shaft extends out of the door panel 1 to facilitate the control of the rotating assembly 3. A first abutment block 24 and a second abutment block 25 are respectively provided between the windshield 22 and the ventilation plate 21, and the rotation range of the windshield 22 is controlled by the cooperation of the first abutment block 24 and the second abutment block 25 to ensure that the windshield 22 can cover the ventilation hole 23. The first elastic member 26 can be made of a torsion spring. The first elastic member 26 drives the wind shield plate 22 to rotate toward the direction in which the first abutting block 24 and the second abutting block 25 abut against each other, so as to facilitate the resetting of the wind shield plate 22.

[0030] The second elastic member 42 can be made of a material with elastic deformation. A positioning ring 4 is provided at the edge of the ventilation plate 21. The second elastic member 42 provided on the windshield plate 22 and the positioning teeth 41 provided on the positioning ring 4 abut against each other to fix the position of the windshield plate 22. The positioning teeth 41 are arranged in a right angle shape. When the second elastic member 42 moves toward the straight edge direction of the positioning teeth 41, it abuts against the straight edge of the second elastic member 42, thereby preventing the windshield plate 22 from rotating. When the second elastic member 42 moves toward the hypotenuse direction of the positioning teeth 41, the second elastic member 42 is deformed, so that the windshield plate 22 can rotate.

[0031] The rotating shaft 32 and the rotating block 31 are slidably connected to each other, and the windshield 22 is moved away from the ventilation plate 21 by pushing the rotating shaft 32, so that the second elastic member 42 and the positioning tooth 41 are separated from each other, and the windshield 22 rotates in the opposite direction under the elastic restoring force of the first elastic member 26, so as to facilitate the reset of the windshield 22 and completely cover the ventilation hole 23. The limiting ring 43 provided on the side of the positioning ring 4 away from the ventilation plate 21 abuts against the windshield 22 to limit the moving distance of the windshield 22 away from the ventilation plate 21.

[0032] The third elastic member 33 can be made of a spring. The elastic restoring force of the third elastic member 33 is used to drive the wind shield 22 to move toward the ventilation plate 21 to ensure that the wind shield 22 and the ventilation plate 21 fit each other, so that the second elastic member 42 and the positioning tooth 41 cooperate with each other.

[0033] The driving assembly 5 can be made of a driving motor. The driving assembly 5 is arranged in the through slot 11, and the fan blades 52 are driven to rotate by the driving assembly 5, so as to accelerate the gas flow, which is beneficial to improve the ventilation effect. The fan blades 52 are rotatably connected with the output shaft of the driving assembly 5 through the connecting rod 51, and the inclination angle of the fan blades 52 is adjusted by rotating the connecting rod 51. The inclination angle of the fan blades 52 is different, and the efficiency of driving the gas flow is different, thereby changing the speed of the gas passing through the through slot 11 under the fan blades 52, and adjusting the ventilation effect.

[0034] The first telescopic component 55 can be made of an electric telescopic rod. The first telescopic component 55 drives the brush 54 disposed in the groove 53 of the connecting rod 51 to move, and the connecting rod 51 is rotated to make the groove 53 face the ventilation component 2. The first telescopic component 55 drives the brush 54 to move, so that the brush 54 and the ventilation component 2 abut against each other. The brush 54 rotates under the drive of the driving component 5 to clean the ventilation component 2.
