Existing hand-propelled tricycle for disabled persons adopts driven by shaking and has front-wheel to hold direction, uses more convenient.But because crossbeam and front-wheel arranged, compare with wheelchair and to take up room greatlyyer, be not suitable in indoor use; Also, be not easy to carry owing to can not fold.
People wish the advantages with wheelchair and three-wheel handcar, Chinese patent publication number CN2527259Y, on December 25th, open day, and the name of innovation and creation is called: folding utility three-wheel wheel Wheel-chair, this application disclose a kind of three-wheeled collapsible wheel Wheel-chair.Adopt single wheel drive, can back seat is partially folded when on the shelf.Bulky problem when the length of car body did not have minimizing and still solves operation when its deficiency was folding should not be in indoor use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of employing driven by shaking mode is provided, and keeps volume little again simultaneously, the hand wheelchair of collapsible advantage.
This utility model is achieved by following technical proposals.
This utility model be provided with manual setter on the described vehicle frame and be connected in manual setter and trailing wheel between drive mechanism, be provided with direction-control apparatus again, described manual setter includes handle, rocking arm and driving shaft, handle is connected with rocking arm; rocking arm is connected with driving shaft; described direction-control apparatus includes handlebar, axis of orientation and steering wheel, and handlebar is connected with axis of orientation, and axis of orientation is connected with steering wheel.
Described drive mechanism includes a kind of drive mechanism of sprocket chain strip transmission mechanism, also can include two kinds of drive mechanisms of gear drive and sprocket chain strip transmission mechanism, gear drive is connected with the sprocket chain strip transmission mechanism, described manual setter is located at the right side of wheelchair, described direction-control apparatus is located at the left side of wheelchair, described handlebar is provided with rim brake, rim brake is connected with rear wheel brake by brake cable, described gear drive is made up of a pair of orthogonal bevel gear, and described gear drive gear ratio is 3: 1.
This utility model beneficial effect compared with prior art is:
1. adopt the driven by shaking mode, the size and Orientation of active force is more laborsaving than the type of drive of traditional push chairs hand push trailing wheel outer ring when having changed the driving wheelchair by drive mechanism, comfortable and health.
2. kept the wheelchair volume little, folding characteristic, easy to carry, be convenient to indoor use.For the people with disability provides effective instrument from being advanced into the public place, also reduced people with disability or patient dependence simultaneously to household and medical personnel.
