The invention discloses a self-operated running
machine. The self-operated running
machine mainly comprises a running platform, two vertical columns and a display screen, wherein the running platformconsists of a plurality of pedals, two synchronous belts, a rotary shaft, a linking
aluminium disc and sliding rails; the linking
aluminium disc is connected with a rotary shaft at the front end of the running platform; a resistance adjusting rod is arranged on one vertical column and consists of a
handle, a rotary plate, a bottom plate and a pulling
rope; the
handle is arranged on the rotary plate; the bottom plate is fixed on the vertical column; the rotary plate is connected on the bottom plate by a plurality of rolling balls; the top end of the pulling
rope is connected into a clamping groove on the bottom plate, and the bottom end of the pulling
rope is connected onto the rotary plate; the rotary plate is arranged at one side of the pedals by an adjusting rotary shaft; a plurality ofpermanent magnets are respectively arranged at the two sides in the rotary plate. The self-operated running
machine disclosed by the invention has the beneficial effects that a proper reverse rotationforce is generated for the rotary speed of the rotary shaft of the running platform by the resistance adjusting mechanism generated by
cutting a
magnetic field, so that the speed adjustment for the running machine is realized. The self-operated running machine disclosed by the invention has the advantages that the use is flexible and convenient, the application range is wide, the energy can be saved and the fitness effect is good.
