The surface of the sliding block is provided with a limiting block, the limiting block corresponds to the limiting block, and a limiting rod is arranged on the side edge of the limiting block, so that the sliding block can only horizontally move.
The limiting block is hinged with a connecting rod, one end of the connecting rod is hinged to the limiting block, and the other end of the connecting rod is hinged to the adjacent air door.
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 motor is characterized in that a chain wheel A is arranged on an output shaft of the motor, a pneumatic motor can be used as standby power, a chain wheel B is arranged on an output shaft of the pneumatic motor, and the chain wheel A is connected with the chain wheel B through a chain. When the motor is damaged, the pneumatic motor can be started to output power.
Furthermore, the number of the limiting blocks on the outer surface of the sliding block is two, and the two limiting blocks are designed in a symmetrical mode. The limiting blocks are respectively hinged with connecting rods, one ends of the connecting rods are hinged to the limiting blocks, and the other ends of the connecting rods are hinged to the inner faces of the adjacent air doors.
The utility model discloses during the use, driving motor or pneumatic motor drive the drive gear A of gearbox, and drive gear A drives drive gear B, and drive gear B rotates that also is exactly the lead screw and rotates. When the screw rod rotates, the end threads of the screw rod are mutually reverse threads, and the two sliding blocks move oppositely due to the limiting action of the limiting blocks on the sliding blocks. The slider moves to drive the connecting rod, and the connecting rod pushes and pulls the air door to open and close.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use adopts same power supply and synchronous power transmission structure when the air door switching, has realized opening and closing when subtend air door, very big improvement application safety factor. 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, the utility model relates to a screw rod centralized control is to opening air door, including power unit, drive mechanism and air door main part.
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 connected with a gearbox 9, a driving gear A8 is integrally arranged on the output shaft of the gearbox 9, and the driving gear A8 is meshed with a driving gear B5. The driving gear B5 is provided with a screw rod 6 in the middle, and the driving gear B5 is fixedly connected with the screw rod 6.
