Abstract
The utility model provides an adjusting device for a backrest of a wheelchair. The adjusting device comprises an arc-shaped adjusting plate and a limiting rod, wherein the arc-shaped adjusting plate is hinged onto a chair frame and provided with an arc-shaped limiting groove, the outer side edge of the arc-shaped limiting groove is toothed, a handle is assembled at the upper end of a backrest frame and connected with the upper end of a connecting rod via a spring, the lower end of the connecting rod is hinged onto a connecting arm of the arc-shaped adjusting plate, and one end of the limiting rod is fixedly connected to the lower end of the backrest frame while the other end of the limiting rod is located in the limiting groove. When the backrest of the wheelchair is required to be adjusted, the handle is gripped, the connecting rod is pulled via the spring and drives the upper end of the arc-shaped adjusting plate to rearwards rotate around the lower end of the arc-shaped adjusting plate via the connecting arm, so that the limiting rod is withdrawn from teeth of the arc-shaped limiting groove, and then the backrest can be adjusted. The adjusting device has the advantages that the adjusting device is convenient in adjustment, as one end of the arc-shaped adjusting plate is hinged on the chair frame, a force application point is fixed relatively, and performances of the adjusting device are more stable during adjustment.
