The invention relates to a wheelchair leg frame quick adjustment mechanism. The wheelchair leg frame quick adjustment mechanism comprises an adjustment positioning strip fixed on a wheelchair main frame, wherein a plurality of protrusions are arranged at the inner side of the adjustment positioning strip, a modularized assembling part is fixed on the adjustment positioning strip through an adjustment spanner, the modularized assembling part can move up and down on the wheelchair main frame, a foot frame rod is connected to the modularized assembling part, a pedal is fixed at the lower end of the foot frame rod, different horizontal directions of the foot frame rod can be converted on the modularized assembling part, and the modularized assembling part fixes a positioning shaft pin between the protrusions of different heights through the adjustment spanner to adjust different heights of the pedal. The wheelchair leg frame quick adjustment mechanism is compact in structure, simple in part structure, convenient to machine, capable of adjusting the height and the horizontal angle of the pedal, simple in adjustment, and high in operability.
Description
technical field [0001] The invention relates to a quick adjustment mechanism for a leg frame of a wheelchair, which is an adjustment structure capable of quickly and easily adjusting the height and horizontal direction of the leg frame of a wheelchair, and belongs to the field of wheelchairs. Background technique [0002] Wheelchairs are the basic means of transportation for people with walking disabilities in their feet or legs. People sitting in wheelchairs usually put their feet on the pedals, and the position and height of the feet remain unchanged, which is not conducive to the rehabilitation of such people. Therefore, a wheelchair with adjustable footrest height has become a demand. [0003] In the prior art, tools such as wrenches are needed to adjust the height of wheelchair pedals, and the adjustment process is relatively complicated: the clamping device needs to be loosened first, and when the leg frame is adjusted to the desired height position, the clamping devic...
