Technological scheme: stator controlling mechanism before of the present utility model, contain final controlling element, transmission shaft, final controlling element connects transmission shaft; Also contain upper encloser, lower encioser, cylindrical shell, main rotary shaft, main crank, active blade, joint shaft bearing, turn-take, driven crank, driven rotatingshaft, passive blade.Final controlling element is in the outside of upper encloser, the periphery of upper encloser and lower encioser cylindrical shell, main crank, joint shaft bearing, turn-take and driven crank at the outer surface of cylindrical shell, main rotary shaft and driven rotatingshaft pass cylindrical shell, active blade and passive blade are in the inside of cylindrical shell.Transmission shaft connects main rotary shaft, and main rotary shaft connects main crank and active blade, and main crank connects joint shaft bearing, joint shaft bearing connects turn-takes, turn-take and connect driven crank by joint shaft bearing, driven crank connects driven rotatingshaft, and driven rotatingshaft connects passive blade.
In the utility model, also contain two backing pins, limit the initial position and the final position of turn-taking and rotating respectively, the maximum angle that rotates of turn-taking is 5 °-30 °, turn-take when turning to final position by initial position, the corresponding rotation angle of active blade and passive blade is 0 °-90 °.
Described final controlling element is electronic, perhaps also has the manual tune handle.After the final controlling element action, cause that finally active blade and passive blade rotate, change the angle of blade, thereby regulate air output.
Described cylindrical shell is a cylinder type.
Described active blade and passive blade are fan-shaped; Active blade is 1, and passive blade is 5-15.When closed, active blade and passive blade are evenly distributed on the same circular cross-section of inner barrel, and the gap between each blade of active blade and passive blade is 0.2-5mm.
Described joint shaft bearing contains roller and the roller shaft that can regulate length and degree of tightness.
Described main rotary shaft and active blade are an integral body, and driven rotatingshaft and passive blade are an integral body.Be connected with the copper sheathing of lubricate between main rotary shaft, driven rotatingshaft and the cylindrical shell.
Beneficial effect: compact structure of the present utility model, easy installation and removal, it is little to regulate the keying resistance, can effectively regulate inlet air flow, guarantees airflow smooth, significantly improves the drafting efficiency of the blower fan of this controlling mechanism of assembling.And can be connected electric actuator or the driving of manual tune handle, flexible operation is regulated accurately, and is safe and reliable.
