Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a shaft-stabilized centrifugal fan comprises a fan body 1 and a mounting seat 2 arranged at the bottom end of the fan body 1; the fan is characterized in that a notch 3 is formed in the mounting seat 2, a spring piece 6 is arranged in the notch 3, and the bottom end of the fan body 1 is fixedly connected with the spring piece 6 through a connecting plate 7; a plurality of mounting holes 8 are uniformly formed in the bottom end of the spring piece 6, idler wheels 9 are rotatably mounted in the mounting holes 8, and sliding grooves 12 are formed in positions, corresponding to the idler wheels 9, of the inner bottom end of the notch 3; a plurality of second springs 11 are uniformly and fixedly connected to the inner bottom end of the notch 3, one ends of the second springs 11 are fixedly connected with push plates 10, and the push plates 10 are fixedly connected with the spring pieces 6 through connecting rods;

when the fan body 1 works to generate vibration, the fan body 1 compresses the spring piece 6, the vibration can be absorbed, the stability of the fan body 1 is improved, and when the spring piece 6 is compressed, two ends of the spring piece 6 extend towards two sides, the idler wheel 9 slides in the sliding groove 12, so that two ends of the spring piece 6 compress the second spring 11 through the push plate 10;

the second spring 11 is extruded through the spring piece 6, so that the shock is absorbed more thoroughly;
