Track-adjustable rehabilitation mechanism for synergetic exercise of limbs

The invention discloses a track-adjustable rehabilitation mechanism for synergetic exercise of limbs. The mechanism comprises a lower limb training device, an upper limb training device and a rack, wherein the lower limb training device adopts a crank block structure and comprises a crank, a first connecting rod, a sliding block, a guide track and a pedal; the upper limb training device adopts an II level rod assembly structure and comprises a second connecting rod, a rocking bar and a handle; one end of the crank is hinged to the rack, the other end of the crank is hinged to the head end of the first connecting rod, the tail end of the first connecting rod is hinged to the sliding block, and the sliding block slides on the guide track; the pedal is mounted on a pedal support rod connected to the first connecting rod; one end of the second connecting rod is hinged with the middle of the first connecting rod, the other end of the second connecting rod is hinged with the lower end of the rocking bar, the middle of the rocking bar is hinged to the rack, and the handle is mounted at the upper end of the rocking bar. The track-adjustable rehabilitation mechanism is simple and compact in structure, has better rigidity, can be bridged to other rehabilitation training instruments and can meet the demands for range-adjustable synergetic rehabilitation training of the upper and lower limbs.
