But, existing air quantity control technique mainly as variable-frequency control technique, the interrupted start-stop technology of blower fan, manually tie up air duct technology etc. and all have defect; Wherein, variable-frequency control technique cost costliness; The interrupted start-stop technology of blower fan easily makes the extremely unstable of distinguished and admirable change; Manually tie up wind band and can cause windage to increase, thereby ventilator is caused to adverse effect.For this reason, be necessary to invent a kind of volume adjusting apparatus of with low cost, convenient operation.
Model utility content
The utility model is for the deficiencies in the prior art, and object is to provide one can, according to needs of production, can regulate the fan leaf angular adjustment apparatus of air quantity and wind direction easily.
For achieving the above object, the utility model is explained a kind of fan leaf angle regulator, its key is: comprise angle adjustment plate, operating stem and connecting plate for being fixed on flow blower casing outer side surface, wherein said operating stem top is connected with described angle adjustment plate, middle part is connected with the first set screw nut for fixing fan leaf rotating shaft, and the middle part of bottom and described connecting plate is hinged; Be hinged with respectively the first adjustable lever and the second adjustable lever at described connecting plate front and rear, on described the first adjustable lever and the second adjustable lever, be fixed with respectively the second set screw nut and the 3rd set screw nut for fixing fan leaf rotating shaft.
In actual production, in the time that needs regulate air quantity, rotating operation bar is to predetermined angular orientation, operating stem by connecting plate drive the first adjustable lever and the second adjustable lever servo-actuated, controlling fan blade rotatingshaft drives fan leaf to turn to predetermined angle, and operating stem is fixed on angle adjustment plate, and then fan leaf angle is fixed, thereby realize the adjusting of fan blade angles.By above-mentioned fan blade angle controlling device, can be for different Environmental Conditions and the Various Seasonal of blower fan, the air quantity to blower fan and wind direction regulate easily.
Described angle adjustment plate is sector structure, near being provided with a row spacing hole on this angle adjustment plate arc outer edge, thereby wears caging bolt in a described spacing hole therein and realize the connection of described operating stem and angle adjustment plate.
Sector structure is convenient to produce, and has saved the material of angle adjustment plate simultaneously, has saved the cost of production of this device; While regulating fan leaf angle, operating stem is turned to after predeterminated position, by caging bolt being fixed in the spacing hole of required angle, described operating stem is fixed on angle adjustment plate, thereby fan leaf angle is fixed, realize fan leaf angle adjustment.
Described spacing hole is nine, and the center of circle of nine these spacing holes is positioned on same circular arc.
Multiple spacing holes are set like this, can, according to the needs of different production, Environmental Conditions and Various Seasonal, regulate the fan blade angle of blower fan, make the Applicable scope of this blade angle adjusting device for fan more extensive.
In actual production, described connecting plate is hinged by rotating shaft and described operating stem, the first adjustable lever and the second adjustable lever respectively.
Realize connecting plate and the hinged annexation that can make of described operating stem, the first adjustable lever and the second adjustable lever is more firm, the working life of extension fixture by rotating shaft.
Remarkable result of the present utility model is: modern design, simple in structure, regulate the angle of fan leaf by operating stem, and be fixed on spacing hole and lever position is fixed by caging bolt, the angle of fan leaf is fixed, can be for the different Environmental Conditions of blower fan and season, the air quantity to blower fan and wind direction regulate easily.
