Abstract
Disclosed is a double-driving-wheel linkage wheelchair. Inner sides of double driving wheels of the wheelchair are respectively provided with a transmission gear, a transmission shaft parallel to shafts of the double driving wheels is arranged below a seat of the wheelchair and above the shafts of the double driving wheels of the wheelchair, one end of the transmission shaft is fixed with a fixing gear, the fixing gear is meshed with a transmission gear fixed at one end of a rear wheel at the same end of the fixing gear, the other end of the transmission shaft is integrally connected with a spline shaft, the spline shaft is engaged with a movable gear provided with a spline shaft hole, and a shifting fork rod is arranged above the movable gear. Through the double-driving-wheel linkage wheelchair, the double driving wheels can be switched between linkage and non-linkage, a user can control the wheelchair to advance, draw back and turn by a single hand, and then hemiplegia patients and other patients with one-side upper limbs having dysfunction can independently move by aid of the wheelchair. In addition, the double-driving-wheel linkage wheelchair further can be used for rehabilitation train and is simple in structure, weight of the wheelchair is seldom increased, and then load to users is low..
Description
Technical field
This utility model belongs to wheelchair medical and that the people with disability uses, particularly a kind of dual drive wheel interlock wheelchair.
Background technology
At present, known manual wheelchair structure is by seat, driving wheel, and castor, and some adnexaes constitute.Have the hands circle on the driving wheel, the user both hands simultaneously promote the hands circle forward or backward, wheelchair is advanced or retreat; When the right-hand man promotes the speed of hands circle when inconsistent, wheelchair will turn to the left or to the right.This kind structure makes comparatively maneuverability of wheelchair, but there is a deficiency: when hemiplegia or other side upper limb have handicapped patient when driving wheelchair, because its right-hand man's function gap is bigger, the bilateral driving wheel of wheelchair is rotated synchronously, wheelchair can only spin, normally forward-reverse.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of dual drive wheel interlock wheelchair is provided.For overcoming the deficiency that existing manual wheelchair wheelchair hemiplegia or other side upper limb have handicapped patient to use, this manual wheelchair can not only use for the sound patient of bilateral upper limb as traditional manual wheelchair, and can have handicapped patient to use for hemiplegia or other side upper limb, make it promptly use one hand can independently control wheelchair.Especially being fit to hemiplegic patient and other needs uses the patient of wheelchair to use.
The technical solution of the utility model is:
A kind of dual drive wheel interlock wheelchair is characterized in that: the inboard at the dual drive wheel of wheelchair respectively is provided with a travelling gear, and travelling gear is coaxial and be fixedly connected on the dual drive wheel inboard with dual drive wheel; The top of the below, seat of wheelchair and the dual drive wheel axle of wheelchair is provided with a power transmission shaft parallel with the dual drive wheel axle, power transmission shaft is connected on the wheelchair frame by bearing, one end of power transmission shaft is fixed a fixed gear, fixed gear and the travelling gear engagement of holding a fixed end on the trailing wheel together, what the other end of power transmission shaft was connected as a single entity is splined shaft, cooperate the free gear that the spline axis hole is arranged on splined shaft, shifting fork bar is arranged above free gear, the shifting fork bar upper shaft is connected on the wheelchair frame.
The shifting fork bar control box is arranged on wheelchair frame, and control box is passed in the shifting fork bar upper end, and the convex spring leaf that cooperates gear shift with shifting fork bar is arranged in the control box.
This utility model effect is:
This dual drive wheel interlock wheelchair is in the operational approach that does not change the conventional manual wheelchair, increased the device of dual drive wheel interlock, make dual drive wheel switch between and not linking in interlock, the user one hand is steerable wheel chair forward-reverse and turns to, make hemiplegia or other side upper limb have handicapped patient also can independently use wheelchair activities, can also be used for the rehabilitation training (during the driving wheel interlock, hands movement is suffered from strong hand-motion), and it is simple in structure, weight increase to wheelchair is less, and the burden of user is less.
Description of drawings
Fig. 1 is the structural representation of dual drive wheel interlock wheelchair
Among the figure: 1 travelling gear, 2 travelling gears, 3 fixed gears, 4 free gears, 5. power transmission shaft, 6 shifting fork bars, 7 wheelchair frames, the splined shaft portion of 8 power transmission shafts, 9 dual drive wheel axles, 10 dual drive wheels, 11 shifting fork bar fixed axis, 12 shifting fork bar control boxes, 13 convex spring leafs.
The specific embodiment
Dual drive wheel interlock wheelchair is as shown in Figure 1 being installed a power transmission shaft 5 below the seat of manual wheelchair and above the dual drive wheel axle 9, and its axial connecting line with dual drive wheel 10 is parallel, does not stand away but do not overlap, and power transmission shaft is connected on the wheelchair frame 7 by bearing.In the inboard, axle center of dual drive wheel, each fixedly mounts the identical travelling gear 1,2 of a size, travelling gear and driving wheel interlock.Fix a fixed gear 3 in a side of power transmission shaft, this gear with the gear interlock on the side drive wheel.The other end of power transmission shaft becomes splined shaft 8 or hexagonal shaft by cylindrical shaft.Axis hole identical with the offside size of movable installation is the free gear 4 of foil or hexagon axis hole on this end foil axle or hexagonal shaft, but its centre bore is a hexagon, can rotate simultaneously with power transmission shaft to reach it, but but the purpose of move left and right.On the wheelchair armrest limit of this side a shifting fork bar 6 that falls " Y " shape is installed, gear is blocked at the two ends of its jaw, to control its move left and right, shifting fork bar fixed axis 11 is connected in the shifting fork bar bearing 8 on the wheelchair frame, shifting fork bar control box 12 is arranged on wheelchair frame, control box is passed in the shifting fork bar upper end, and the convex spring leaf 13 that cooperates gear shift with shifting fork bar is arranged in the control box.The upper end of shifting fork bar places in the control box, and shifting fork bar can be stirred gear shift at the two ends of convex spring leaf, and can place the two ends of the convex spring leaf in the control box, and the convex spring leaf also reaches the purpose of shifting fork bar shift lock.Thereby reach control gear whether with the purpose of gear interlock.When gear and gear interlock, wheelchair dual drive wheel interlock, user can be realized advancing of wheelchair and retreats with one hand; During not interlock, dual drive wheel does not link, and user can be realized turning to of wheelchair with one hand.Thereby reach the purpose whether control wheelchair dual drive wheel links.
