Secondary objective of the present utility model is providing a kind of fan rowing machine, by the rotary resistance of a resistance adjustment device with the control fan, allows the user reach different movement effects.

For reaching the purpose of above-mentioned creation, a kind of fan rowing machine that the utility model is set, comprise a bracing frame, which is provided with slidably seat and two foot-operated pads, sit, step on for the user respectively, but the front end of support frame as described above is provided with the stretching device that the fan and of an one-directional rotation can make fan rotate; Its major technology characteristics are that the front end of support frame as described above is provided with a fixed mount, fixed mount is provided with at least one support portion and one and the driving wheel that is coupling of fan, at the foreign volume of driving wheel and support portion around an elastic threads, and an end of described elastic threads is connected with driving wheel, and the other end is fixed on the fixed mount.

When user's application of force pulling stretching device, elastic threads is reeled and is the energy storage state, and after the user stopped the application of force, elastic threads released energy, and made the stretching device homing.

In addition, be provided with a resistance adjustment device between fixed mount that the utility model is set and the driving wheel, it comprises a brake component of the outer peripheral edges of a tumbler and a contact tumbler, described tumbler and fan are coupling, rotate synchronously with fan, and, then can reach different movement effects according to demands of individuals by the frictional force between elasticity adjustment brake component and the tumbler.

The utlity model has following advantage:

1. the utility model can make assembled components simplify by the elastic reaction of elastic threads, not only can effectively save cost, and can reduce the space that storage is taken in.

2. the utility model can significantly be simplified the member of composition, can effectively reduce the probability that assembly damages in use, and then reduces the expense of maintenance.

3. the utility model passes through the rotary resistance of a resistance adjustment device with the control fan, but elasticity provides different users's demand, and reaches different movement effects.

For ease of more deep understanding being arranged, be specified in the back to the utility model:
