Safer wheelchair device

Abstract

The invention discloses a safer wheelchair device, and relates to the technical field of wheelchairs. A fixed hook is taken down from the top of a supporting and fixing bracket; a safety belt fixing structure is placed above the supporting arm-chair; a patient is placed above the supporting arm-chair, and when the patient sits on the supporting arm-chair, the abdomen of the patient is protected bya protective bag; the chest of the patient is protected by a protective cover through connecting the contraction ropes; the interior of the fixed hook hooks the exterior of the supporting and fixingbracket; a wheelchair pedal is pushed by reversing the arm-chair push handle with feet; a first gear rotates a second gear; through the rotation angle of a steering roller, the moving track of the wheelchair is adjusted; when the wheelchair pedal is pedaled by loosening the arm-chair push handle, the brake rod enables the deceleration friction plates in a first brake block and a second brake blockto rub and decelerate the rotating speed of the connecting rolling shaft under the action of the connecting block, so that the wheelchair decelerates or stops advancing, and the connecting rolling shaft can be adjusted through the deceleration friction plates to enable the wheelchair to steer and run.
