The cost of use is relatively high, and the worker still needs to close the auxiliary door with force, which does not play an effective role. Therefore, those skilled in the art provide a control structure for an automatic damper in a mine to solve the problems raised in the above background technology. Utility Model Content

[0022] The present application discloses a control structure for an automatic air door in a mine, referring to Figure 1-4 , comprising a door frame 1, both ends of the inner side of the door frame 1 are hinged with a damper body 2, one side of the two damper bodies 2 is provided with a mounting groove 3, one side of the two mounting grooves 3 is hinged with a side door 4, and one end of the two side doors 4 is fixedly mounted with a driving mechanism 5, and one end of the two driving mechanisms 5 is respectively fixedly mounted on one end of the two damper bodies 2. Through the provided driving mechanism 5 and sensor 7, after a person passes through the side door 4, the sensor 7 senses that the person has passed, and the transmission signal drives the driving motor 511, so that the driving motor 511 rotates, and then drives the driving screw 512 to rotate, so that the driving plate 513 moves in the first movable groove 59, compresses the driving spring 514, so that one end of the driving spring 514 pushes the second driving rod 56 to move in the first movable groove 59, and then the first driving rod 55 and the second driving rod 56 extend, pushing the side door 4 to close, which can prevent the staff from forgetting to close the door after passing the side door 4.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The two driving mechanisms 5 each include a first mounting member 51 and a second mounting member 52. The first mounting member 51 is fixedly mounted on one end of the damper body 2, and the second mounting member 52 is fixedly mounted on one end of the side door 4. A first rotating shaft 53 is mounted on the inner side of the first mounting member 51, and a second rotating shaft 54 ​​is mounted on the inner side of the second mounting member 52. The first driving rod 55 and the second driving rod 56 are conveniently rotated on the inner sides of the first mounting member 51 and the second mounting member 52, respectively.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The two driving mechanisms 5 further include a first driving rod 55 and a second driving rod 56. A first connecting hole 57 is formed on one side of the first driving rod 55, and a second connecting hole 58 is formed on one side of the second driving rod 56.

The sensor 7 is provided to facilitate a person passing through the side door 4. After the sensor 7 senses that a person has passed, a transmission signal drives the drive motor 511, so that the drive motor 511 rotates.

[0030] The implementation principle of the control structure of an automatic air door in a mine according to an embodiment of the present application is as follows: through the provided driving mechanism 5 and sensor 7, after a person passes through the side door 4, the sensor 7 senses that the person has passed, and a transmission signal drives the driving motor 511, so that the driving motor 511 rotates, thereby driving the driving screw 512 to rotate, so that the driving plate 513 moves in the first movable groove 59, compressing the driving spring 514, so that one end of the driving spring 514 pushes the second driving rod 56 to move in the first movable groove 59, thereby extending the first driving rod 55 and the second driving rod 56, and the first driving rod 55 and the second driving rod 56 are respectively rotated on the inner sides of the first mounting member 51 and the second mounting member 52, thereby pushing the side door 4 to close, which can prevent the staff from forgetting to close the door after passing through the side door 4.
