Abstract
The utility model relates to a crank rocker driving gear for a wheel chair. The crank rocker mechanism which has no dead points and takes a rocker as main drive is used for replacing a manual moving ring of the wheel chair to drive the wheelchair to move forwards. The operation rocker can be used for operation for forward movement, backward movement, speed change, turning, braking, etc. The utility model has the advantages of no dead points, continuous drive, convenient operation, labor saving, sanitation and relatively high speed and can be used as a tool instead of walk. The utility model is suitable for refitting various wheel chairs and being used in other situations. The no dead point drive of the crank rocker mechanism taking the rocker as the main drive is realized.
Description
The present invention relates to a kind of wheelchair crank rocker driving mechanism, be applicable to the various Wheel-chair repackings of taking turns.
Existingly take turns Wheel-chair generally all to remove ring gymnastics with hands vertical.Its shortcoming, the one, it is too near from tire that hands is removed circle, easily make dirty hands and coat-sleeve.The 2nd, hands is removed the vertical too effort of ring gymnastics, is not suitable for weak old people and uses.The 3rd, the speed of a motor vehicle is too slow, and car is ineffective extremely, not the work done in the manner of a certain author walking-replacing tool.
Wheelchair crank rocker driving mechanism is that to adopt with the rocking bar be that initiatively no dead point crank and rocker mechanism drives wheelchair.By retrieval, have not yet to see patent announcement.
It is no dead point crank and rocker mechanism initiatively with the rocking bar that the purpose of this utility model is to provide a kind of, removes circle to replace the wheelchair driver, drives wheelchair and advances.
Technical solution of the present utility model is: the hands that removes the wheel Wheel-chair is removed circle and stop mechanism, and between wheelchair frame and trailing wheel, installing one additional is no dead point crank and rocker mechanism initiatively with the rocking bar, drives wheelchair.Realization is that the no dead point of crank and rocker mechanism initiatively drives with the rocking bar, and its embodiment has two kinds, and a kind of is on the basis of common crank and rocker mechanism, increases an auxiliary rocker arm, constitutes the crank and rocker mechanism of a band auxiliary rocker arm.By the displacement of auxiliary rocker arm, overcome the dead point of crank and rocker mechanism, be applicable to monolateral driving or bilateral driving.Another kind is that a crank 90 ° the crank and rocker mechanism that staggers is mutually respectively adorned on the wheelchair both sides, forms bilateral driving, and both sides alternately overcome the dead point, thereby has realized being that the no dead point of crank and rocker mechanism initiatively drives with the rocking bar.
The advantage of wheelchair crank rocker driving mechanism is, drives continuously no dead point.Handle that rocking bar can advance, retreats, speed change, turning or kill manipulation such as car.Handiness, laborsaving, health, the speed of a motor vehicle is very fast, can make walking-replacing tool.
Accompanying drawing is the structural representation of an embodiment of the wheelchair crank rocker driving mechanism of this utility model band auxiliary rocker arm.Below in conjunction with accompanying drawing, the present invention is described in further detail.
With reference to accompanying drawing, the axle skin 4 of a transformation of the way is housed on the trailing wheel 1, its outside one end is the shaven head of backshaft skin, is welded with a crank 3 on the shaven head, its centre and an inboard end are the front axle skin structure.Rocking bar 7 is inserted in the centre of connecting rod 5, and auxiliary rocker arm 8 upper end skies are enclosed within on the axle 10 that is fixed in vehicle frame 9, and auxiliary rocker arm 8 lower ends are connected by connecting rod 5 hinges with crank 3, forms the wheelchair crank and rocker mechanism of a band auxiliary rocker arm.Rocking bar 7 front and back in stopper slot 6 are back and forth shaken, and by connecting rod 5 power are passed to the crank 3 that is welded on the skin 4, drive trailing wheel 1 and drive wheelchair.
Under the situation of bilateral driving, can save auxiliary rocker arm 8 and stopper slot 6, a crank 90 ° the crank and rocker mechanism that staggers is mutually respectively adorned on the wheelchair both sides.At this moment, the direct sky of hinge fulcrum of rocking bar 7 is enclosed within on the axle 10, forms bilateral driving, both sides alternately overcome the dead point, drive wheelchair and advance.
Conveniently set up a pocket 2 that makes with fabric in the wheelchair back lower place in order to go out, in order to the usefulness of the belongings of going out.
