Three, summary of the invention: in order to address the above problem, this utility model has designed a kind of tricycle of easy accessibility, the hand three-wheel wheel Wheel-chair of wheel Wheel-chair dual-purpose, and its technical scheme is: front vehicle wheel assembly and hand crank assembly fuse and be fixed on the pedal of seat front.Hand crank is by the sprocket wheel on the transmission system drives hind axle, universal wheel is housed below the pedal, and seat and back wagon box are installed above the rear vehicle shaft.
This hand three-wheel wheel Wheel-chair can be realized multiple function of use by adjusting, it above universal wheel turns to hand-propelled tricycle, universal wheel returns the normal position, shedding front-wheel and hand crank is the wheel Wheel-chair, the people can sit onboard and can lie, also can carry out excrement and urine, very easy to use for people with disability or patient, also alleviated burden for the nurse personnel.
Four, description of drawings: Fig. 1 is the structural representation of hand three-wheel wheel Wheel-chair.
Fig. 2 is the drive system sketch map.
Five, the specific embodiment: hand three-wheel wheelchair Herba Plantaginis wheel assembly shown in Figure 1 comprises steering handle (1) front frame and front-wheel (19), the hand crank assembly comprises hand crank (3), crank sprocket wheel (2), chain (4), lower sprocket (18) and outer casing, they and front frame are connected to one, and are fixed on the pedal of seat front by bolt (5).Hand crank (3) rotates by the transmission system drives trailing wheel garage is walked, drive system as shown in Figure 2, its drive path passes through chain (4) to sprocket wheel (18) by the co-axial sprocket wheel of hand crank (2), by the consubstantiality gear (17) of sprocket wheel (18) through idler gear (16) to gear (20), through chain (13), directive wheel (12) is to the axle upper sprocket wheel (11) of trailing wheel (10) by the consubstantiality sprocket wheel (15) of gear (20).The braking hub is arranged on the hind axle, and the speed by handle (6) control tricycle and that car is stopped is stable has increased idler gear (16) and has made the rotation direction of hand crank (3) identical with the rotation direction of trailing wheel (10) in the drive system.Drive system places below the pedal, and is easy to use, safe, outward appearance is clean and tidy.Shedding bolt (5) can break away from car body from sprocket wheel (18) with preceding wheel assembly and hand crank assembly, and tricycle becomes wheelchair.In order to make wheelchair stable, two universal wheels (14) are housed under the pedal.Universal wheel is to be installed on the pedal by hinge and fixture (such as the fixing head of set bolt connection).Below universal wheel was fixed on when doing the wheelchair use, when doing the tricycle use, loosening set bolt flipped up universal wheel the reuse bolting.Go up installation railway carriage (7) at the axle of trailing wheel (10), the railway carriage front is a seat, and the railway carriage biside plate is made handrail.The railway carriage back is wagon box (9), can place relevant articles for use.The space of wagon box can also make movable adjustable seat back put down backward, patient can sit onboard can lie pleasant.On the medicated cushion of seat portable plate is arranged, make basin on the medicated cushion underneath, patient can carry out excrement and urine onboard, and this sees still that to patient twisting the personnel of protecting all brings convenience.Brake handle (6) is located at the railway carriage side, makes in operation.
