Abstract

The invention relates to a foldable wheelchair which comprises two rear support rods, two front support rods, fork-shaped support tube groups, connecting rods, horn tubes, armrest tubes, foot rack tubes, pedals and seat back cloth. The two rear support rods and the two front support rods form four standing columns of the foldable wheelchair. One fork-shaped support tube group is hinged between every two adjacent standing columns. Two ends of each front support rod are respectively provided with a universal wheel and hinged to one connecting rod, and each horn tube slidably sleeves the other end of the connecting rod. A fixed wheel is disposed on each rear support rod. Two ends of each armrest rod are respectively hinged to the corresponding rear support rod and detachably disposed on the corresponding front support rod. Two ends of each foot rack tube are respectively hinged to the corresponding pedal and the corresponding front support rod. The horn tubes are rotatably hinged and extend relative to the rear support rods. By the arrangement, the foldable wheelchair has the advantages that the rear support rods and the front support rods can be drawn close to each other, the pedals and the foot rack tubes can be retracted, the foldable wheelchair can be folded simply and easily, and space occupation is reduced.
