Benefits of technology

The present invention provides a new rowing machine that can adjust the damping strength to different training intensities and simulate single handed or double handed rowing. The machine has a simple structure and low production cost. The oar components are connected to the rotating shaft through unilateral bearings, allowing for easy rotation and minimal resistance during the return of the oar. The machine also includes a seat back and cylindrical rollers for massage and health care.

Problems solved by technology

This kind of rowing machine with oil cylinder mechanism has disadvantages of high producing cost, easy leakage problem of the oil cylinder and pollution of environment.
When the user pulls the webbing through the handle, the webbing drives the pulley to rotate, and also causes the damping wheel to rotate.
This kind of rowing machine has disadvantages as follows: 1. the webbing is easily broken, which results in increasing of use costs.
2. the user can only pull and return through the handle, but can not achieve a simulation of rowing with both hands; 3. the handle is connected to the damping wheel by the webbing, so both hands need to work at the same time, one hand of rowing can not be achieved; 4, The returning is achieved by the action of elastic element, resulting in unnatural phenomenon of the user's hands when returning.

first embodiment

[0047]Referring to FIGS. 1-10, a rowing machine of the present invention comprises:

[0048]a base 1 with a rack 11 and a slope rail 12;

[0049]a seat cushion 2 slidably coupled to the rail 12;

[0050]a rotating plate 3 with a fixing rotating shaft 31 rotatably assembled to the rack 11 through the rotating shaf 31;

[0051]two oar components 4 respectively connected to the two ends of the rotating shaft 31 by unilateral bearings 51 in universal joining way to unilaterally drive the rotating plate 3 to rotate when swinging;

[0052]a rotation damping mechanism 6 with strength adjustable and assembled to the rack 11; and

[0053]an acceleration type transition transmission mechanism 7 assembled between the rotating plate 3 and the damping mechanism 6 to drive a damping wheel 61 of the damping mechanism when the rotating plate 3 rotates.

[0054]The base 1 further comprises a front base pipe component 13 and a rear base pipe component 14, the front base pipe component 13 is connected to the front portion...

second embodiment

[0063]Referring to FIG. 11, the difference of a rowing machine of this embodiment from the first embodiment is the damping mechanism. The damping mechanism further comprises an electromagnetic component 64, the damping wheel 61 is a magnetic control wheel, the electromagnetic component 64 is assembled to the rack 11 and is coupled to the magnetic control wheel, the electromagnetic component 64 is connected to an electronic control instrument by a wire.

[0064]The damping strength of the damping wheel 61 can be adjusted by adjusting the current of the electromagnetic component 64.

third embodiment

[0065]Referring to FIG. 12, the difference of a rowing machine of this embodiment from the first embodiment is the damping mechanism. The damping mechanism is a windage damping mechanism; the damping wheel is a fan blade 65.

Description

FIELD OF THE INVENTION[0001]The present invention relates to fitness equipment, particularly to a rowing machine.BACKGROUND OF THE INVENTION[0002]Rowing machine is also called boating machine which is a kind of fitness equipment simulating boating. The traditional rowing machine mainly adopts with a left and right handles and an oil cylinder mechanism. The left and right handles are respectively connected to the oil cylinder mechanism, and the damping effect of the left and right handles in the shaking process is realized by using the oil cylinder mechanism. This kind of rowing machine with oil cylinder mechanism has disadvantages of high producing cost, easy leakage problem of the oil cylinder and pollution of environment. The rowing machine in current technology (as disclosed in the Chinese patent database with publishing number CN203425451U) has the handle connected to a webbing, the webbing is connected to a pulley, and the pulley drives the damping wheel. When the user pulls th...
