[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 5 The utility model provides a specific technical implementation scheme of the structure of a fan hub body:

[0023] A structure of a hub body of a fan comprises: a hub body 1, a fixing sleeve 2, an assembly seat 3, a shaft head 4, a hexagon socket bolt 5, an avoidance groove 6, a reinforcing rib 7, and an assembly hole 8; the middle of the hub body 1 is an integrated structure with a fixing sleeve 2, and the middle of the front end of the hub body 1 is an integrated structure with an assembly seat 3; the shaft head 4 is fixedly mounted on the front end of the hub body 1 by the hexagon socket bolt 5, and the outer wall of the shaft head 4 is an integrated structure with an avoidance groove 6; the reinforcing rib 7 is welded between the hub body 1 and the fixing sleeve 2; and the assembly holes 8 are cross-shaped and arranged at four locations around the assembly seat 3.

[0024] Specifically, the hub body 1 is in a truncated cone shape, and a circular concave assembly seat 3 is provided in the middle of the hub body 1. The assembly seat 3 in the middle of the hub body 1 can be used to install the fan blades therein by bolts, so that when the blades are damaged, they can be replaced one by one without replacing all of them, thereby reducing costs.

[0025] Specifically, the shaft head 4 is in a conical shape, and four arc-shaped avoidance grooves 6 are arranged in a cross-shaped distribution around the shaft head 4. The conical shape of the shaft head 4 can reduce wind resistance and wind noise, and the avoidance grooves 6 can also be placed between blades to generate conflicts.

[0026] Specifically, the reinforcing ribs 7 are right-angled triangular plate-shaped structures, and the reinforcing ribs 7 are welded between the hub body 1 and the fixing sleeve 2 in a cross-shaped distribution. The reinforcing ribs 7 can improve the firmness between the hub body 1 and the fixing sleeve 2 and improve the safety performance in use.
