The speed reducer transmits power to the driving gears, the driving gears are four in number, and the four driving gears correspond to the single air door respectively. The meshing of drive gear is equipped with the arc rack, the arc rack has the curved shape rack form of tooth for the one side, and it has tooth one side and drive gear meshing, every arc rack and single drive gear meshing, and every arc rack one end is articulated with corresponding air door inner face.
And each arc-shaped rack is individually tensioned by a tensioning device so as to ensure the motion track of the arc-shaped rack.
Furthermore, the power mechanism adopts a double-power mode and is provided with standby power.
Further, the standby power setting mode is as follows: the standby power can adopt a pneumatic motor, a transmission gear C is arranged on an output shaft of the pneumatic motor, a transmission gear D is arranged on the transmission shaft corresponding to the transmission gear C, and the transmission gear C is meshed with the transmission gear D. When the motor is damaged, the pneumatic motor can be started to output power.
Further, the speed reducer passes through worm gear drive with power transmission to drive gear, and the concrete mode of setting up of worm gear is ripe prior art, and this is no longer repeated here.
Further, the inner surface of the air door is provided with an arc-shaped rack bracket through a connecting rod, and the radian of the bracket is the same as that of the arc-shaped rack so as to further restrict the motion track of the arc-shaped rack.
When the invention is used, the motor or the pneumatic motor is driven to drive the transmission shaft to rotate, and the transmission shaft rotates to transmit power to the speed reducers at two ends. The speed reducer transmits power to the four driving gears through the worm and gear mechanism, and the driving gears rotate to drive the arc-shaped racks to rotate according to a certain track, so that the air door is driven to be opened and closed. And because the speed reducers of the opposite air doors are opposite to each other, the four air doors arranged in opposite directions can be controlled to be opened or closed simultaneously.
The invention has the beneficial effects that: the invention has simple structure and convenient use, adopts the same power source and synchronous power transmission structure when the air door is opened and closed, realizes the simultaneous opening and closing of the opposite air doors and greatly improves the safety factor of use. And, through the setting of reserve power, guaranteed the steady operation of air door, make its operation safer firm.

Detailed Description
Referring to fig. 1 and 2, the single-door single-gear centralized control split type air door of the present invention includes a power mechanism, a transmission mechanism and an air door main body.
The power mechanism can adopt a motor 13, and the motor 13 drives a transmission mechanism to control the air door 1 to be opened and closed simultaneously. The air door main body is a split type inward closing air door in the prior art.
The transmission mechanism is arranged in the following form: the output shaft of the motor 13 is fixedly provided with a transmission gear A7, the transmission gear A7 is meshed with a transmission gear B11, the transmission gear B11 penetrates through the transmission shaft 10, two ends of the transmission shaft 10 are respectively connected with the speed reducers 9 through couplers, the speed reducers 9 at two ends are opposite, namely the speed reducer 9 of the air door 1 at one side is a forward speed reducer 9, and the speed reducer 9 at the other side is a reverse speed reducer 9.
The speed reducer 9 transmits power to the driving gears 4, the number of the driving gears 4 is four, and the four driving gears 4 are respectively arranged corresponding to the single air door 1. The meshing of drive gear 4 is equipped with arc rack 3, arc rack 3 is the curved shape rack form that the tooth has in the one side, and it has tooth one side and drive gear 4 meshing, and every arc rack 3 meshes with single drive gear 4, and 3 one end of every arc rack is articulated with 1 inner face of corresponding air door.
Each arc-shaped rack 3 is individually tensioned by the tensioning device 2 to ensure the movement track thereof.
