Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 7, the centrifugal fan impeller of the present invention includes: an outer ring 1; an inner ring 2; and a blade assembly 3 connecting the outer ring 1 and the inner ring 2, the blade assembly 3 fixing the outer ring 1 and the inner ring 2.
The inner ring 2 has a rotating shaft 4 in the middle, and the rotating shaft 4 is used for connecting with a motor. The blade assembly 3 comprises a fixing piece 5 and a blade piece 6, wherein the fixing piece 5 is installed on the inner ring 2, and the fixing piece 5 is provided with a limiting part 7 and a guide part 8. The blade member 6 is mounted on the fixing member 5, the guide portions 8 are arranged on both sides of the blade member 6, the guide portions 8 are provided with guide grooves 9 in the middle, rollers 10 are arranged in the guide grooves 9, and the rollers 10 are connected with the blade member 6 through connecting rods 11. After the upward movement of the blade member 6, the roller 10 can move up and down in the guide groove 9.
Meanwhile, the blade piece 6 is provided with a plurality of mounting grooves 12, the mounting grooves 12 are internally provided with an elastic piece 13 and a nut 14, the middle of the elastic piece 13 is provided with a second spring 15, one end of the elastic piece 13 is spherical, the other end of the elastic piece 13 is hollow, one end of the second spring 15 is in contact with the inside of the elastic piece 13, the other end of the second spring is in contact with the nut 14, and the limiting part 7 is provided with a plurality of spherical grooves 16 matched with the elastic piece 13.
When the blade element 6 moves upwards, the second spring 15 can be compressed, and then the elastic element 13 is extended into the spherical recess 16 at a different position. However, the elastic member 13 is not fully extended, and the extended portion of the elastic member 13 is not fully pushed out by the second spring 15 because the extended portion is at a diameter position of the whole round sphere.
