Problems solved by technology

[0003] Existing wheelchairs generally do not have a speed limiting device, which causes the existing wheelchair to go too fast when going downhill, causing the existing wheelchair to hit other objects or topple over, causing the user to be injured. Not only that, the existing wheelchair cannot adjust the angle of the backrest , resulting in reduced patient comfort when using existing wheelchairs

Abstract

The invention relates to a wheelchair with a decelerating function. The wheelchair comprises a bracket, a rotation shaft, a seat chair, a backrest, and adjusting mechanism, two armrests, two auxiliarywheels and two support wheels, wherein speed limiting mechanisms are arranged at two ends of the rotation shaft, the adjusting mechanism comprises a support unit and two fixing units, each fixing unit comprises a pushing assembly, a telescopic assembly and two fixing ropes, the support unit comprises a handle, a connecting rod, a fixing shaft, a gear, a rack and a movable block, each speed limiting mechanism comprises a speed limiting plate, a rotation room, a friction plate and a plurality of popup units, and each popup unit comprises a popup groove, a second spring and a friction block. Forthe wheelchair with the decelerating function, through the adjusting mechanism, people can adjust the angle of the backrest according to the demands, so that the comfort when people use the wheelchair is improved, moreover, through the speed limiting mechanisms, during downhill movement, the movement speed of the wheelchair can be limited, so that the phenomenon that the wheelchair collides withother articles or topples over is avoided, and further, a user is protected against injuries.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wheelchair with deceleration function. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body. Wheelchairs are important tools for rehabilitation. Wheelchairs are not only for the physically disabled and It is a means of transportation for people with disabilities, and more importantly, it enables patients to perform physical exercises and participate in social activities with the help of wheelchairs. [0003] Existing wheelchairs generally do not have a speed limiting device, which causes the existing wheelchair to go too fast when going downhill, causing the existing wheelchair to hit other objects or topple over, causing the user to be injured. Not only that, the existing wheelchair cannot adjust ...
