Controls the difficulty of rotating the winding unit 30. Specifically, when the user pulls the pull cord 42 out of the pedal 10, the pull cord 42 drives the first guide wheel group 37 and the first pulley 34 to rotate in the first direction. Then the second mandrel 32 is rotated synchronously, and the rotation of the second mandrel 32 drives the coaxial second pulley 36 and the second pulley 272 synchronously. Rotate in the first direction, so that the elastic rope 44 having the opposite winding direction to the pull rope 42 is wound back to the second pulley 36 and is in a stretched state, and the first pulley 271 passes through the belt 29 and the second pulley 36. The two pulleys 272 are driven to rotate synchronously, so that the coaxial one-way ratchet 232 drives the first mandrel 23 to rotate synchronously in the first direction, and then the pin 25 is linked to drive the flywheel 24 to rotate.

When the user removes the force applied to the pull cord 42, the elastic force of the elastic cord 44 will drive the elastic cord 44 in the stretched state to reset, thereby providing a reverse pulling force, so that the second pulley 36 is pulled toward the second direction. rotate, and synchronously drive the second mandrel 32 to rotate in the second direction, and the coaxial first pulley 34 is driven by the second mandrel 32 to rotate synchronously, and the pull rope 42 is taken back to the first pulley 34 according to the trend. The first pulley 271 is driven by the belt 29 and the second pulley 272 to rotate in the second direction synchronously. At this time, the one-way movement mechanism of the one-way ratchet 232 prevents the reverse pulling force of the elastic rope 44 from being transmitted to the first mandrel 23 and the flywheel 24, and the moment of inertia of the flywheel 24 cannot be transmitted to the second mandrel 32 through the first pulley 271, so that the first mandrel 23 and the flywheel 24 are in an idling state.

It can be seen from the above that when the user's hands simultaneously or alternately and alternately exert pulling force on the pull rope 42, the pulling force fitness equipment 1 of the present invention induces a magnetic attraction force with the flywheel 24 through the magnetic field of the electromagnet, which hinders the first mandrel 23. With the rotation of the flywheel 24, the user needs to exert a greater force on the pull rope 42 to overcome the rotational resistance of the first mandrel 23, so that the pull rope 42 can be pulled out of the main body 12, thereby effectively enhancing the training of the chest muscles and arm muscles. strength. The present invention combines the step pedal and the tension rope, so that the user can selectively exercise the upper body and the lower body. In addition to exercising different parts, the adjustable resistance device 20 such as an electromagnet and an aluminum flywheel can be used to control and adjust the pulling difficulty of the tension rope. To provide users with practical and interesting sports equipment.
