Magnetic control means of body -building apparatus

The utility model provides a magnetic control means of body -building apparatus, it is installed and produce the resistance on the body -building apparatus and to the flywheel, magnetic control means comprises a master control piece and magnetic ordering row group, it installs in the body -building apparatus and provides magnetic ordering row groups and erect in the flywheel below still to have two at least locating levers, the master control piece mainly is the drive and controls the magnetic ordering row and organize the removal on two at least locating levers and change the resistance of flywheel, master control piece control magnetic ordering row are organized and can carry out coaxial and parallel lateral displacement below the flywheels, when the user operates the body -building apparatus, the control magnetic ordering row of controlling that see through the master control piece are organized and are carried out coaxial and parallel lateral displacement in the below of flywheel, utilize the change of distance between magnetic ordering row group and the flywheel and form the increase and decrease of magnetic ordering row group and flywheel overlapping area, cause reluctance force size and displacement to present the linear scale relation. The utility model discloses reach the production of controlling the flywheel resistance quickly accurate, provide the user easy operation, see through the formation that the flywheel resistance can effectively be adjusted to simple construction package.
