Abstract

The utility model discloses a water pressure artificial muscle which comprises a sealing end connector, an elastic rubber pipe, a high-strength fiber mesh grid, a water passing end connector, two end buckle pressing rings, two middle buckle pressing rings and two back taper tooth surface buckle pressing rings. When the water pressure artificial muscle works, under the action of the water pressure, the elastic rubber pipe and the high-strength fiber mesh grid deform, the diameter of the water pressure artificial muscle is increased, the length is decreased, and therefore tensile force action on a driving object connected with a thread blind hole of the sealing end connector is generated. The water with the certain pressure is sealed in the elastic rubber pipe, due to the fact that high-strength fibers are tightly woven to form the tubular high-strength fiber mesh grid, the elastic rubber pipe is covered by the high-strength fiber mesh grid, and the water pressure artificial muscle can bear the large enough interior water pressure. Due to the buckle pressing action of the buckle pressing rings and the structural action of back taper tooth surfaces and a protrusion shoulder, the water pressure artificial muscle can bear large tensile loads, and the high-strength water pressure artificial muscle is formed.
