Abstract
A gravity ball comprises a ball body. The ball body is compounded by using multiple layers of spherocolloid. A woven-belt reinforcing rib is compounded on the surface of at least one layer of spherocolloid. The present invention has a rational structure, high strength and a long service and is difficult to damage.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A gravity ball, comprising a ball body consisting of multiple layers of spherocolloid wherein a woven-belt reinforcing rib is compounded on the surface of at least one layer of spherocolloid.
2 . The gravity ball according to claim 1 , characterized in that the woven-belt reinforcing rib is compounded with more than one layer of spherocolloid except the outermost layer of spherocolloid.
3 . The gravity ball according to claim 1 , characterized in that the woven-belt reinforcing rib is compounded on the surface of the spherocolloid in a crisscrossed way.
4 . The gravity ball according to claim 3 , is characterized in that the width of the woven-belt reinforcing rib is ⅓˜⅙ the diameter of the spherocolloid.
5 . The gravity ball according to claim 3 , characterized in that the woven-belt reinforcing ribs on two adjacent layers are staggered by an angle.
