Furthermore, the louver structure comprises a frame, a plurality of louvers are arranged in the frame at intervals up and down, and two ends of the louvers are connected with a louver synchronous connecting plate through a louver transmission connecting plate; the window at the bottom is connected with the window synchronous connecting plate through a transmission lever, and the bottom end of the transmission lever extends downwards and is connected with a hinge connecting rod.
Furthermore, the end part of the window is connected with the window transmission connecting plate through a transmission bolt, and the end part of the window positioned at the bottommost end is connected with a transmission lever through the transmission bolt.
Furthermore, a push rod end flange sleeve is arranged at the free end of the electric push rod and is connected to the center of the air door connecting plate through a push rod end hinge shaft.
Furthermore, the bottom of the electric push rod is connected to the push rod support through a push rod support hinge shaft.
Compared with the prior art, the utility model has the following beneficial effects: the utility model has simple structure, stable performance, reliable use and convenient operation, can realize automatic control and save manpower; compared with the control mode of the frequency converter, the utility model reduces the control mode to about 1/3 in the prior art, and has low cost; the air volume adjustment is realized by opening and closing the shutters, the air volume adjustment is fine, and the effect is obvious; meanwhile, synchronous adjustment of air ports on two sides of the fan is achieved through the electric push rod, the adjusting effect is stable, and the occupied space is small.

The air door structure comprises an electric push rod 1, an air door connecting plate 2, a window leaf synchronous connecting plate 3, a reducing flange 4, a window leaf 5, a window leaf transmission connecting plate 6, a hinge connecting rod 7, a push rod seat hinge shaft 8, a push rod support 9, a push rod end hinge shaft 10, a push rod end flange sleeve 11, a transmission bolt 12 and a transmission lever 13.
Detailed Description
A specific gravity air selection shutter type adjusting mechanism is shown in figures 1-3 and comprises a pair of reducing flanges 4 arranged on air inlets at two sides of a fan, wherein shutter structures are arranged on the reducing flanges 4; a window synchronous connecting plate 3 is arranged below the louver structure; a push rod support 9 is arranged on one side of the fan, an electric push rod 1 is hinged to the push rod support 9, and the electric push rod 1 is obliquely arranged; the free end of the electric push rod 1 is connected with air door connecting plates 2, the air door connecting plates 2 appear in pairs, and the two ends of the two air door connecting plates 2 are connected through hinge connecting rods 7; the louver structure comprises a frame, a plurality of louvers 5 are arranged in the frame at intervals up and down, and two ends of the louvers 5 are connected with a louver synchronous connecting plate 3 through a louver transmission connecting plate 6; the window leaf 5 at the bottom end is connected with the window leaf synchronous connecting plate 3 through a transmission lever 13, and the bottom end of the transmission lever 13 extends downwards and is connected with a hinge connecting rod 7.
The end part of the window 5 is connected with the window transmission connecting plate 6 through a transmission bolt 12, and the end part of the window 5 at the bottommost end is connected with a transmission lever 13 through the transmission bolt 12; a push rod end flange sleeve 11 is arranged at the free end of the electric push rod 1, and the push rod end flange sleeve 11 is connected to the center of the air door connecting plate 2 through a push rod end hinge shaft 10; the bottom of the electric push rod 1 is connected to a push rod support 9 through a push rod seat hinge shaft 8.
When the fan works, the electric push rod 1 is controlled to do telescopic motion through a circuit, the end part of the electric push rod 1 stretches out and draws back to drive the air door connecting plate 2 through the hinge shaft 10 at the end part of the push rod so as to synchronously open and close the air doors at two sides of the fan, the flange sleeve 11 at the end part of the push rod plays a role in prolonging the contact area between the hinge shaft 10 at the end part of the push rod and a hole, the eccentric overlong is prevented from entering a motion dead point, then the air door connecting plate 2 drives the transmission lever 13, the transmission bolt 12 is used as the center of a circle to rotate, and because the cylindrical surface of the transmission bolt 12 is provided with a processing plane, so that the window leaves 5 which are correspondingly processed with square holes can be driven to swing, the other end of the transmission lever 13 drives all the window leaves to open and close together through the window leaf synchronous connecting plate 3, therefore, the effect of adjusting the size of the air inlet to control the air volume change is achieved, and the air volume change of the whole fan can be controlled only by a stroke within 100mm when the electric push rod 1 acts in the embodiment.
