Specific embodiment
The structural principle of the utility model and working principle are described in detail with reference to the accompanying drawing:
As shown in Figure 1-3, a kind of manual air volume control valve, including rectangular frame 1, the inside of frame 1 are transversely arranged more
A blade 2, the both ends of each blade 2 are installed with shaft 3, and the two sidewalls of frame 1 are equipped with the bearing being socketed with shaft 3, leaf
Piece 2 is vertical with 1 side wall of frame, and it is ipsilateral and connect with transmission mechanism 4 that one end shaft 3 of each blade 2 stretches out frame 1, is driven
Mechanism is used to rotate the angle of multiple blades 2 to adjust the size of air-supply；
As shown in Fig. 2, transmission mechanism 4 includes pivoted arm 41, connecting rod 42, straight connecting rod 43 and driving device 5, each shaft 3 is
It is vertically fixed with isometric pivoted arm 41, adjacent rotor arms 41 extend to two sides along its length, and adjacent rotor arms 41 are one group, every group
Hinged with connecting rod 42 respectively between pivoted arm 41, ipsilateral pivoted arm 41 is also hinged with straight connecting rod 43 respectively；Driving device 5 includes being connected
Adjustment plate 51 on the side wall of frame 1, adjustment plate 51 is parallel with the side wall of frame 1, and adjustment plate 51 is equipped with to be connected with shaft 3
And coaxial rocker arm shaft 52, vertically connected Rocker arm 53, adjustment plate 51 are equipped with fan-shaped sliding slot 55 to 52 other end of rocker arm shaft, and sector is sliding
Slot 55 and rocker arm shaft 52 are coaxial, are equipped with tight lock part between Rocker arm 53 and fan-shaped sliding slot 55.
Tight lock part includes jack (being not drawn into figure) corresponding with fan-shaped sliding slot on Rocker arm 53, and clamping screw 56 sequentially passes through
The other end and the locking nut 57 of fan-shaped sliding slot 55 and jack, clamping screw 56 connects.
Locking nut 57 is wing nut, facilitates and Rocker arm 53 is locked in adjustment plate 51.
Clamping screw 56 be dormant bolt, can by the countersunk head and locking nut 57 of bolt by Rocker arm 53 in adjustment plate 51
It clamps, plays the role of locking, the blade for adjusting angle 2 is prevented to be rotated further by.
Blade 2 in the present embodiment is equipped with a plurality of reinforcing rib 21 along its length, for improving the intensity of blade 2.
The inside of frame 1 is equipped with sealing strip 6 corresponding with blade, when blade 2 completely closes, in blade 2 and frame 1
Sealing strip 6 fits, and improves the leakproofness under volume damper closed state.
The course of work of the utility model is as follows: as shown in Fig. 2, driving rocker arm shaft 52 to rotate by rotation Rocker arm 53, shaking
Arm axle 52 and shaft 3 are connected, so shaft 3 rotates in same direction with Rocker arm 53.
When rocker arm shaft 52 rotates clockwise, the pivoted arm 41 connected with it is rotated clockwise, with hinged another of straight connecting rod 43
One group also rotates clockwise with swivel arm 41, and the corresponding shaft 3 being connected to above-mentioned pivoted arm 41 also rotates clockwise, with above-mentioned shaft
3 connected respective vanes also rotate clockwise.
Since two adjacent pivoted arms 41 are to extend along its length to two sides, between one group of pivoted arm 41 again with connecting rod 42
Hingedly, so when rocker arm shaft 52 rotates clockwise, another effect of pivoted arm 41 through connecting rod 42 in same group turns counterclockwise
Dynamic, the shaft 3 being connected with above-mentioned pivoted arm 41 also rotates counterclockwise, so that the blade 2 being connected with above-mentioned shaft 3 be driven to turn counterclockwise
