Title:
WATER-RESISTANCE ROWING EXERCISE MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/033244
Kind Code:
A1
Abstract:
Provided is a water-resistance rowing exercise machine, comprising a bracket (100), and a water tank (1), linkage mechanism (2), and angle adjustment mechanism fixed to the bracket (100); the water tank (1) is internally provided with a first impeller wheel (11) and a second impeller wheel (12); the first impeller wheel (11) comprises a first plate part (111) and a plurality of first blades (112) distributed on the periphery of the first plate part (111); the second impeller wheel (12) comprises a second plate part (121) and a plurality of second blades (122) distributed on the periphery of the second plate part (121); the angle adjustment mechanism is used for adjusting the angle of relative rotation between the first impeller (11) and the second impeller (12) so that the first blade (112) and the second blade (122) may be near to or far away from one another. The angle of relative rotation between the first impeller (11) and the second impeller (12) is adjusted, thus the distance between the first blade (112) and the second blade (122) can be adjusted, thereby adjusting the resistance to which the two impeller wheels (11, 12) are subjected when rotating in the water tank (1), achieving the function of adjusting the magnitude of resistance of the water-resistance rowing exercise machine.
