Description of the embodiments
The utility model is described in detail below with reference to the attached drawings:
as shown in fig. 1, the present embodiment provides an air flow guide vane synchronous adjustment mechanism for adjusting the angle of an air flow guide vane 2 provided on an impeller housing 1.
The synchronous adjusting mechanism of the air flow guide vane comprises a driving frame 3, a first connecting rod 5 and a second connecting rod 6; the driving frame 3 is rotatably arranged on the impeller shell 1; the driving frame 3 is provided with first connecting rods 5 with the same number as that of the airflow guide blades, and the first connecting rods 5 can rotate around connecting nodes with the driving frame 1; a second connecting rod 6 is rotatably connected to each first connecting rod 5; each second connecting rod 6 is fixedly connected to one air flow guiding vane 2.
In order to facilitate the rotational control of the drive frame 3, the drive frame 3 is mounted on a guide rail 9 on the impeller housing 1 via rollers 7.
In order to facilitate the installation of the roller 7, a roller installation hole 31 is formed on the driving frame 3, see fig. 4.
In order to facilitate the installation of the first link 5, a link installation hole 32 is formed in the driving frame 3, see fig. 4.
The lower end opening of the first connecting rod 5 is connected with the driving frame 3 through a pin shaft 8, the upper end opening of the first connecting rod 5 is connected with the second connecting rod 6 through the pin shaft 8, the second connecting rod 6 is blocked with the convex handle of the guide vane 2, and the guide vane 2 can rotate in the hole of the impeller shell 1.
The drive frame 3 further comprises a drive handle 4 by means of which the angle of rotation of the drive frame can be controlled manually or automatically. When the 3 frames are driven in a rotating way, the first connecting rod 5 and the second connecting rod 6 are driven to rotate for a certain angle, so that the guide vane 2 rotates for a certain angle.
