Abstract
The utility model discloses a braking device for a hand-operated wheelchair. The braking device comprises a front direction frame, a back frame, a front direction driving wheel and a back wheel, wherein the upper end of the front direction frame is provided with a hand-operated driving shaft; the hand-operated driving shaft is provided with a braking flywheel and a driving chain wheel; one-way rotating devices are arranged in the braking flywheel and the driving chain wheel; the braking flywheel is provided with a brake cable traction block; the brake cable traction block is connected with a brake cable; the hand-operated driving shaft is provided with a hand operating arm; and when the hand operating arm is operated forwards for driving a chain wheel to drive the wheelchair to move forward, the braking flywheel can be driven to tension the brake cable for baking the wheelchair by pulling the hand operating arm forwards during braking. The braking device has the advantages that: the braking flywheel is used for controlling the brake cable, so that a front wheel and the back wheel can be braked; and a certain buffering process is performed, so that the wheelchair is more stable and effective during braking, and operation is more convenient and simpler.
Description
Technical field
The utility model relates to a kind of hand Wheel-chair of taking turns, and especially relates to a kind of hand Wheel-chair brake gear of taking turns.
Background technology
The hand Wheel-chair of taking turns is the desirable walking-replacing tool of lower part of the body disabled person, because of the operator can only with the hands drive, hold direction and control brake, thus brake gear has been proposed various requirement, as want hand with convenient, effective, simple.
Summary of the invention
The utility model technical matters to be solved provides the hand Wheel-chair brake gear of taking turns of a kind of easy to operate actv..
The utility model solves the problems of the technologies described above the technical scheme that is adopted; A kind of hand Wheel-chair brake gear of taking turns; Comprise the place ahead to frame, back vehicle frame and the place ahead to driving wheel and trailing wheel; Said the place ahead is provided with the shaking axle drive shaft to the upper end of frame; Described shaking axle drive shaft is provided with the brake flywheel, and described brake flywheel is provided with the brake cable guiding piece, is connected with brake cable on the described brake cable guiding piece.
The direction frame of described shaking axle drive shaft front end is provided with limiting stopper; Described brake cable is passed described limiting stopper and is installed in hand brake equipment of taking turns on Wheel-chair front-wheel or the trailing wheel and is connected; Brake cable between described limiting stopper and the said brake equipment is provided with spacing flexible pipe, and the brake cable between described limiting stopper and the described brake cable guiding piece is provided with spring.
Described brake flywheel is made up of cover in the flywheel and flywheel casing and nut cap; Described shell two sides are provided with grooving and lid groove; Described flywheel casing center is provided with positioning shaft hole, and the cover center is provided with positioning sleeving shaft in the described flywheel, and cover and nut cap are movably arranged on described grooving and cover in the groove in the described flywheel; Described grooving arranged outside has the screens skewed slot; Cover is provided with the screens groove in the described flywheel, is provided with activity screens piece in the described screens groove, and described activity screens piece inboard is provided with spring.
Described shaking axle drive shaft is provided with power chain, is provided with the unidirectional rotation device between described power chain and the described shaking axle drive shaft, and described power chain is provided with chain, and described chain drives steering wheel and travels forward.
Also be provided with hand arm on the described shaking axle drive shaft, described hand arm is provided with hand crank.
Compared with prior art, the utility model has the advantages that and utilize brake wheel control brake cable, can brake front-wheel and trailing wheel, and certain buffering course is arranged, can make the wheel Wheel-chair more steadily, effectively like this, operate also convenient, simple at glancing impact.
It is power that hand arm shakes forward, and hand arm pulled backwards is brake, does not resemble existing hand flywheel of taking turns on the preceding driving wheel of the direct use of Wheel-chair and stops; Hand is once drawing wheel inactive like this; Do not have buffering course, dangerous, the flywheel that is installed on the driving wheel also is very easy to damage.
