Abstract
This invention discloses an exercise machine with adjustable resistance. The exercise machine includes a fluid container, one or more paddles, a driving device, and an adjusting device. The one or more paddles are arranged in the fluid container into which a fluid is poured. The driving device comprises an adjusting rod to couple with the one or more paddles. The driving device transmits a user's force for driving the one or more paddles to rotate. The adjusting device can adjust a depth of the one or more paddles in the fluid, so as to provide differing degrees of resistance for the one or more paddles.
Claims8
An exercise machine, comprising:
- a fluid container into which a fluid is poured;
- one or more paddles arranged in the fluid container;
- a driving device comprising an adjusting rod to couple with the one or more paddles, the adjusting rod configured to rotate the one or more paddles via a force exerted on the driving device by a user;
- an adjusting device for adjusting a depth of the one or more paddles in the fluid, so as to provide different degrees of resistance for the one or more paddles;
- wherein the adjusting device comprises a knob and a linking mechanism coupled with the knob and the adjusting rod, and the knob can be rotated so as to adjust the depth of the one or more paddles via the linking mechanism;
- and
- wherein the linking mechanism comprises a lateral tube, a base, a pivotal base, a linking arm, and a nut, and wherein the lateral tube is arranged between and connected with two side tubes of the exercise machine, the pivotal base couples to a bottom of the lateral tube, the base fixes with the linking arm and pivotally couples with the pivotal base, the knob is threaded to engage with the nut and then fixes with the base, and a front end of the linking arm couples with the adjusting rod.
An exercise machine, comprising:
- a fluid container into which a fluid is poured;
- one or more paddles arranged in the fluid container;
- a driving device comprising an adjusting rod to couple with the one or more paddles, the adjusting rod configured to rotate the one or more paddles via a force exerted on the driving device by a user;
- an adjusting device for adjusting a depth of the one or more paddles in the fluid, so as to provide different degrees of resistance for the one or more paddles;
- wherein the adjusting device comprises a control knob, and an upper portion or end of the adjusting rod is threaded to engage with an internal thread of the control knob, and wherein the control knob is rotated to make an upward or downward movement of the adjusting rod.
An exercise machine, comprising:
- a fluid container into which a fluid is poured;
- one or more paddles arranged in the fluid container;
- a driving device comprising an adjusting rod to couple with the one or more paddles, the adjusting rod configured to rotate the one or more paddles via a force exerted on the driving device by a user;
- an adjusting device for adjusting a depth of the one or more paddles in the fluid, so as to provide different degrees of resistance for the one or more paddles;
- wherein the adjusting device comprises a shaft, a control member, an outer shell, two springs, a supporting plate, and a connecting member, and wherein the supporting plate is fixed with the exercise machine, the shaft passes through the outer shell and has an upper end coupled with the supporting plate and a lower end coupled with an upper supporting tube of the exercise machine, the control member is inserted into an aperture of the outer shell, the two springs are arranged inside the outer shell, each spring includes a first end coupled with an inner wall of the outer shell and a second end coupled with the control member, and the connecting member includes a front end coupled with the adjusting rod and a rear end coupled with the outer shell.
