Abstract

The invention discloses an air door device. The air door device comprises a door frame, two paralleled transmission shafts arranged in the door frame rotatably, and a blocking plates fixedly arranged on the corresponding transmission shafts, wherein one end of one transmission shaft is provided with a handle, and the other end of each transmission shaft extends out of the door frame and is connected through a transmission device. The air door device can drive the two blocking plates to be opened or closed synchronously only through one handle, enables flows to be increased or decreased stably, and is simple and convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a damper device which uses a baffle to open and close an opening through which a fluid passes to control flow. Background technique [0002] In a general manual damper device, two rotating shafts are arranged in the door frame of the damper, and a baffle plate is fixed on each rotating shaft, and each rotating shaft and the baffle plate are driven to rotate by a handle arranged at one end of the rotating shaft. [0003] The disadvantage of this arrangement is that: the baffles must be opened or closed one by one in order, and the operation time is long; or multiple people must be arranged to operate at the same time, which wastes human resources. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a manual damper device that only needs one handle to drive two baffles to open or close synchronously. [0005] In order to solve the above-mentioned technical problems, the ...
