[0006] There is an annular convex ring A on the outer periphery above the upper part; there is an annular convex ring B on the outer periphery below the lower part; the outer diameter of the outer periphery above the upper part is smaller than the outer diameter of the outer periphery below the lower part.
[0007] There are several vertical convex strip-shaped reinforcing ribs on the outer periphery of the bearing seat.
[0008] There is a fan-shaped hollow A below the circular concave hole A; there is a fan-shaped hollow B above the circular concave hole B.
[0009] The diameter of the circular concave hole A is larger than the inner diameter of the bearing installation hole, and the inner diameter of the bearing installation hole is larger than the inner diameter of the through hole at the center of the lower part.
[0010] The upper peripheral diameter above is 24.5 mm, and the lower peripheral diameter below is 25.5 mm.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. Compared with existing products, the structure of this product adopts an overall lengthened clamping structure for effective confinement;
[0013] 2. At the same time, in order to achieve better shock absorption effect, 10 reinforcing ribs are distributed at the lengthened part in the middle of the product to enhance the shock absorption effect;
[0014] 3. Adopting a barrel-shaped semi-solid design enables the product to have better inclusiveness and be applicable to wind blades of different weights without jitter. Description of the Drawings
