Abstract:
Disclosed is a convenient stepless counterweight mechanism for fitness equipment, comprising a fixed frame fixedly connected to the ground. The fixed frame is rotatably connected to a tensioning cone and a fixed cone. A variable speed friction ring connecting the tensioning cone to the fixed cone is arranged between the tensioning cone and the fixed cone. The center of the tensioning cone is fixedly connected to a tensioning cone central shaft. The tensioning cone is rotatably connected onto the fixed frame by means of the tensioning cone central shaft. A cone tension spring is arranged on the axial direction of the tensioning cone central shaft. The center of the fixed cone is fixed to a fixed cone central shaft. The fixed cone is rotatably connected onto the fixed frame by means of the fixed cone central shaft. A pull rope collector is arranged on one end of the fixed cone central shaft. A pull rope is wound on the pull rope collector. The present application has the effects of reducing a waste of resources, reducing the weight of the fitness equipment, and making it freer to adjust a counterweight.
