Adopt the technical program, change two blades up and down into by an entire plate of prior art, its area of every, weight reduce, and rotate to open closed dynamic loading and reduce greatly, and rotary inertia diminishes, the running balance.Space required during blade rotation reduces relatively, and anti-seismic performance improves, and the action meeting of air door is more steadily reliable.
Further be that described driving shaft and driven shaft lay respectively at the pivot position of active blade and passive blade.
Because being the horizontal centre position from framework, the air-conditioning air intake enters, therefore, driving shaft and driven shaft lay respectively at the state of the pivot position of active blade and passive blade, the angle that blade is opened, position, size can satisfy the needs of air-conditioning air intake just, reach air intake effect preferably.And, the axial dimension minimum that blade is opened, it is the most steady to turn round.
Further be that described driving shaft and driven shaft are meshing with each other with driving gear and driven gear in the end of diaxon.
The technical program can directly be carried out transmission in the end of diaxon with driving gear and the driven gear mode of being meshing with each other by driving shaft and driven shaft, and so structure is the simplest, compactness, and transmission is the most direct, and fault is less, and it is little to take up room, and manufacturing cost is also low.
Further be that described driving shaft is by motor-driven.
The technical program drives operation by motor as power source.Gear and blade all move with uniform velocity, and the dynamic loading of mechanism reduces greatly.
Further be to cooperate transmission by key and keyway between described driving shaft and the driving gear, driven shaft and driven gear.Key and keyway cooperate the transmission of can moving reliably.
Further be, described key and keyway are flat key, and a part is positioned in the middle of the gear axis hole, the outer outside, gear shaft hole that is exposed at of a part, and the length of keyway is connected with axle by screw on the exposed parts of key greater than the length sum of key and 2 times of gear axis holes.So structure when needs are dismantled, screws off screw, and key is shifted out the gear axis hole, driving shaft and driving gear, and driven shaft and driven gear just can be separated.Guaranteed dismounting, maintenance fast and accuracy.
When the blade of air door need be opened, motor action drove driving shaft and rotates, owing to have key to be connected between driving gear and the driving shaft, did not produce relative rotation, so master gear and driving shaft rotate synchronously; Driven gear and driving gear engagement is simultaneously rotated, owing to have key to be connected between driven gear and the driven shaft, do not produce relative rotation, so driven shaft and driven gear rotate synchronously, thereby realized splitting of driving shaft blade and driven shaft blade, air flows to opposite side from the slit of splitting.When air door needs closure, the motor backward rotation, the direction of rotation the when rotation direction of all the other all parts and door opening, thereby the closure of realization blade have been cut off flowing of air.
