Floating ball

The utility model relates to a float ball, including the spheroid, an attaching lug has on the spheroid, the spheroid outward also the parcel be provided with reticular strengthening rib, wherein the strengthening rib is including the warp direction strengthening rib and the latitudinal direction strengthening rib that are interweaved, the one end of multi-strip warp direction strengthening rib intersect in said attaching lug. Strengthening rib among the float ball has the guard action to the spheroid, has reduced water and to spheroidal wearing and tearing, has increased spheroidal life. The strengthening rib can also effective spheroidal shape of protection in addition, prevents to issue the shape of changing in the impact of water, has avoided that float ball takes place to tear, damaged phenomenon.
