Abstract

A sport wheelchair comprises a chair-shaped wheelchair frame which is composed of a chair seat, handrails and a chair back. Two sides of front-back part at the lower end of wheelchair frame are respectively installed with a guiding wheel and a main wheel. The upper end of chair back of wheelchair frame is installed with a hand-push handle. A bracket positioned on the front lower part of chair seat is rotatablely installed with a lower limb movement device which comprises a rotating shaft, a crank and a pedal. The rotating shaft is rotatablely installed at the front end of bracket. Two ends of the rotating shaft are respectively installed with a crank. The other end of crank is installed with the pedal. A main shaft is installed between two main wheels. A lower limb movement transmission mechanism is installed between the main shaft and the rotating shaft. The invention has an advantage that the upper limb and lower limb of wheelchair user is exercised by external force driving through the upper-lower front-back rotation of movement handle of upper limb movement device and pedal of lower limb movement device driven by the main shaft. The healing effect of cerebral thrombosis patient, people with upper limb or lower limb disability and the public with physical disability caused by motor nerve blocking of old people is increased.
