Wheelchairs are an important rehabilitation tool for the elderly and the disabled. With the help of wheelchairs, physical exercises and social activities can be carried out.
Ordinary wheelchairs are generally composed of four parts: a wheelchair frame, wheels, brakes, and a seat.
The hand-cranked wheelchair adds a set of hand-cranked driving device to the ordinary wheelchair.
According to the material, it is divided into aluminum alloy wheelchair and steel tube wheelchair. Aluminum alloy is relatively light.
But the price is also higher than that of ordinary steel-tube wheelchairs.
According to the type, it is divided into ordinary wheelchairs, hand-operated wheelchairs, leisure wheelchairs, high-back wheelchairs, toilet-type wheelchairs, and electric wheelchairs.
There are several kinds of wheelchairs with diameters of 12, 15, 18, and 20cm.Small wheels with large diameters can easily overcome small obstacles and special carpets.However, the large diameter makes the space occupied by the entire wheelchair larger and it is inconvenient to move.The normal small wheel is before the big wheel, but it is a wheelchair used by paraplegics.The small wheel is often placed after the big wheel.It should be noted that the direction of the small wheel is better to be perpendicular to the big wheel, otherwise it is easy to tip over.
