Abstract
The invention provides a push-pull rod type manual automatically-walking wheelchair vehicle. One end of a tube-shaped push-pull rod is hinged to a vehicle frame, the moderate position is hinged to a driving connecting rod, and the driving connecting rod is hinged to a crank fixed to a driving wheel center. When a user pushes or pulls the push-pull rod, the wheelchair vehicle can be driven to walk forwards or backwards. A gear is mounted at the lower end of a driving handle, and a rack is mounted in the push-pull rod. When the driving handle is rotated, the rack is driven by the gear to do rectilinear motion in the push-pull rod, a steering wheel is driven by the rack through a steering pull rod, a movable connecting rod, a steering level and a short pull rod to rotate around a frame body, and the steering of the wheelchair vehicle is realized. A braking handle is mounted on the driving handle, a braking pull wire is connected to a pull wire braking system mounted on the steering wheel through a pipe cavity of the push-pull rod, and the braking handle is pulled to brake the wheelchair vehicle. A sliding groove is formed in the crank to slide the connecting point between the driving connecting rod and the crank to the driving wheel center. When an accompanied person pulls the wheelchair vehicle, the push-pull rod is enabled to stop swinging up and down.
Description
Affiliated field: the present invention relates to the manual self-propelled wheel Wheel-chair of a kind of push-and-pull rod-type, belongs to mechanical manufacturing field.
Background technology: current known manual its type of drive of self-propelled wheel Wheel-chair has two kinds, one stirs cartwheel fashion with both hands to drive, another kind is that hand sprocket wheel drives with chain, above-mentioned two kinds of type of drive one do not meet human engineering operate inconvenience, two be turn to dumb, be not suitable for slope road especially to travel or the use such as single armed people with disability, hemiplegic patient, also easy operator damaged.
Summary of the invention: in order to overcome the above-mentioned deficiency of existing Manual wheelchair vehicle, the invention provides the manual self-propelled wheel Wheel-chair of a kind of push-and-pull rod-type, be characterized in that operator realizes advancing or retreating with the push-pull bar pushed away or draw wheel-chair to be provided with, realize left or right turn with turning handle, handle is also provided with the brakes in advancing simultaneously, even if make operator's single armed operate the advance that also can realize wheel-chair, reversing, left, right turn and braking, in order to prevent when chaperoning personnel's go-cart on push-pull bar, lower swing brings inconvenience to operator, the present invention is also provided with crank and drive link pin joint sliding system, when pin joint slides into driving wheel axle center, push-pull bar stops swinging.
Technical scheme: by one end of tubulose push-pull bar and vehicle frame hinged, push-pull bar freely can be rotated around fulcrum, fixedly driving crank is housed in driving wheel axle center, end and the drive link of crank are hinged, and both freely can rotate around junction point.The other end of drive link and the moderate position of push-pull bar is hinged and make between drive link and push-pull bar can flexible rotating, like this, to push-pull bar power pushing away or draw, drive link pushes away or pulls crank that wheel is rotated forward or backward, achieves the object of walking forward or backward with push-pull bar driving wheel Wheel-chair.
Gear is equipped with in the lower end of driving handle, push-pull bar is built with tooth bar, steering link is equipped with in one end of tooth bar, steering link passes through movable rod, steering lever and short rod are connected with turning to support arm, during with hands rotating drive handle, tooth bar in the gear driven push-pull bar of driving handle lower end does rectilinear motion in push-pull bar, rack drives steering linkage, movable rod and steering lever, steering lever drive short rod, short rod drives and turns to support arm that deflecting roller frame body is rotated, and realizes wheel-chair and turns to.
Driving handle is equipped with brake handle, and brake pulling wire links trailing wheel by push-pull bar tube chamber, trailing wheel is equipped with cable brake system, moves brake handle and the bracing wire of brakes on trailing wheel can be pulled to make wheel-chair realize braking.
Crank is provided with sliding tray, and the pin joint of drive link and crank is slided into driving wheel axle center, and when chaperoning personnel's driving wheel Wheel-chair, push-pull bar stops swinging up and down, and facilitates riding people to get on and off.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention will be further described
As shown in drawings, 1, brake handle 2, driving handle 3, push-pull bar 4, steering link 5, brake pulling wire 6, tooth bar 7, gear 8, drive link 9, slide lock link closely 10, crank 11, driving wheel 12, vehicle frame 13, movable rod 14, steering lever 15, short rod 16, deflecting wheel support bracket 17, damper brake 18, deflecting roller 19, brake holder 20, turn to support arm
; Hinged between push-pull bar 3 and vehicle frame 12, push-pull bar 3 is hinged with drive link 8, drive link 8 is hinged with crank 10, crank 10 is fixedly connected with driving wheel 11, and driving wheel 11 is hinged with vehicle frame 12, when operator hold drive handle 2 to push away or pull push-pull bar 3 time, push-pull bar 3 drives drive link 8, drive link 8 pairs of cranks 10 impose the power pushing away or draw, and make crank 10 drive driving wheel 11 to rotate forward or backward, achieve the object that wheel-chair moves ahead or moves backward.
With hands rotating drive handle 2, gear 7 is rotated, carry-over bar 6 moving linearly in push-pull bar 3 is with by gear 7, tooth bar 6 drives steering link 4, steering link 4 drives movable rod 13 to do rectilinear motion, movable rod 13 drives steering lever 14 around its fulcrum, thus driving short rod 15, short rod 15 drives the support arm 20 that turns to be fixedly connected with deflecting roller 18 that deflecting roller 18 is rotated, and realizes wheel-chair and turns to.
Moving brake handle 1 can drive brake pulling wire 5 to move to brake handle 1 direction, and brake pulling wire 5 drives the damper brake 17 in brake holder 19 to pressurize to deflecting roller 18, realizes the braking of wheel-chair.
When chaperoning personnel's driving wheel Wheel-chair, drive link 8 and the slide lock of crank 10 pin joint can be linked closely and 9 unclamp the core wheel place that pin joint slided into driving wheel 11 and to link closely 9 lockings by slide lock.Push-pull bar can be realized no longer swing up and down, in order to avoid damage operator.
