The invention discloses a pulling force stepless regulation counterweight power generation mechanism and a body builder with the same. The pulling force stepless regulation counterweight power generation mechanism comprises a pulling
rope, a winding drum, a mounting seat, a central shaft, a spring, a power generator and a
regulator. One end of the pulling
rope is connected with the winding drum, and one part of the pulling
rope is wound on the
peripheral wall of the winding drum. The winding drum is rotationally connected with the mounting seat, the outer end of the spring is connected with the winding drum, and the inner end of the spring is connected with the mounting seat. The central shaft is rotationally arranged on the mounting seat, and the winding drum can be arranged on the central shaft in a unidirectional rotating sleeving manner, so that when the pulling rope drives the winding drum to rotate, the central shaft rotates along with the winding drum, and meanwhile, the spring is tightened. The central shaft is connected with a
motor shaft of the power generator which is connected with the
regulator. According to the mechanism, the pulling force process and the power
generation process are organically combined together, the
regulator is used for regulating rotation damping of the
motor shaft of the power generator to regulate the pulling force in a phase-changing mode, therefore, stepless adjustment of the pulling force can be achieved, and
chemical energy consumed by the
human body in the exercise process can be converted into
electric energy for use.
