Abstract
The utility model relates to an article for daily use, in particular to a one-foot drive wheel chair, which is characterized by mainly comprising a pedal, a crank rocker mechanism, a small sprocket, a chain, a big sprocket, a parallelogram steering mechanism, a steering pole, a brake device and a wheel chair bracket, wherein the pedal is fixed on the wheel chair bracket through a bearing; the crank rocker mechanism is connected to the pedal and the wheel chair bracket through bearings; the small sprocket is welded on the crank rocker mechanism; the big sprocket is welded on a rear wheel cross bar; the parallelogram steering mechanism is connected to the small sprocket through screws; and the brake device is fixed on the pedal through screws. The utility model has the beneficial effects that the one-foot drive wheel chair is low in cost and is convenient to use, and the pedal is shaken by foot to drive a crank to rotate, so the small sprocket fixed on the crank rocker rotates, and simultaneously, the small sprocket drives the big sprocket to rotate by the chain and makes a rear wheel roll forwards. The one-foot drive wheel chair is applicable to people with only one hand and one-hand action ability, and people without double arms or double arms incapable of applying power.
Description
Technical field:
This utility model relates to a kind of daily living article, and particularly a kind of single foot drives wheelchair.
Background technology:
Investigation shows; The Chinese population age composition has begun to get into veteran form; The people with disability accounts for national population about 5%; Wherein only hands, the crowd who only has one-handed activities ability (like hemiplegia, hemiplegia), no both arms or both arms not to have an effect account for a very big part, and they are in great demand to wheelchair, and the user of wheelchair is distributed in big small city and vast rural area.Therefore, wheelchair should adapt to different people.Existing wheelchair is divided into two big types: 1, hand-rail type wheelchair: traditional push chairs generally all is that both hands drive; Operation is hard, and can not satisfy only hands, only the crowd's that one-handed activities ability (like hemiplegia, hemiplegia), no both arms or both arms can not have an effect use arranged.2, electric wheelchair: electric wheelchair involves great expense; For the low consumption crowd, can't pay the expense of costliness like this, and; Electric wheelchair generally needs to control advancing, turn to and braking of wheelchair with hands; For making bimanual crowd, electric wheelchair is not suitable for, and it is high especially to need not manual wheelchair cost.
Summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of single foot to drive wheelchair, solve the above-mentioned handicapped people problem of going on a journey, and cost is lower, can satisfy most of crowd and use.
Its technical scheme is: mainly be made up of pedal, crank and rocker mechanism, minor sprocket, chain, hinge wheel, parallelogram steering mechanism, turning-bar, brake unit and wheelchair support, described pedal passes through bearing fixing on the wheelchair support; Crank and rocker mechanism is connected on pedal and the wheelchair support through bearing; Minor sprocket is welded on the crank and rocker mechanism; On hinge wheel welding and the trailing wheel cross bar; Parallelogram steering mechanism is through on screw connection and the minor sprocket; Brake unit is fixed on the pedal through screw.
This wheelchair shakes pedal by foot, drives bent axle and rotates, and the minor sprocket that is fixed on the rocking bar is rotated, and minor sprocket is driven the rotation of hinge wheel and made trailing wheel roll forward by chain simultaneously.When turning to, the foot turning-bar that swings is accomplished the change of direction.During braking, lift the leg pressing brake handle, the braking of traction rear wheel brake skin friction trailing wheel.
The beneficial effect of this utility model is: cost of manufacture is low; Easy to use; Shake pedal by foot, drive bent axle and rotate, the minor sprocket that is fixed on the rocking bar is rotated; Minor sprocket is driven the rotation of hinge wheel and is made trailing wheel roll forward by chain simultaneously, and it is applicable to only hands, the crowd who only has one-handed activities ability (like hemiplegia, hemiplegia), no both arms or both arms not to have an effect.
Description of drawings:
Accompanying drawing 1 is the structural representation of this utility model;
Accompanying drawing 2 is arrestment mechanism partial view of this utility model;
Accompanying drawing 3 is crankshaft installed partial view of this utility model;
Accompanying drawing 4 is the partial view that turn to of this utility model;
Among the last figure: pedal 1, crank and rocker mechanism 2, minor sprocket 3, chain 4, hinge wheel 5, parallelogram steering mechanism 6, turning-bar 7, brake unit 8, wheelchair support 9.
The specific embodiment:
In conjunction with accompanying drawing 1-4, this utility model is done further to describe:
This utility model mainly is made up of pedal 1, crank and rocker mechanism 2, minor sprocket 3, chain 4, hinge wheel 5, parallelogram steering mechanism 6, turning-bar 7, brake unit 8 and wheelchair support 9, and described pedal 1 passes through bearing fixing on wheelchair support 9; Crank and rocker mechanism 2 is connected on pedal 1 and the wheelchair support 9 through bearing; Minor sprocket 3 is welded on the crank and rocker mechanism 2; On hinge wheel 5 welding and the trailing wheel cross bar; Parallelogram steering mechanism 6 is through on screw connection and the minor sprocket 3; Brake unit 8 is fixed on the pedal 1 through screw.
The operating process of this wheelchair is following:
(1) drives: after user is taken wheelchair, put into turning-bar 7 to lower limb;
Foot is placed on the pedal 1, and crank rotates and drives minor sprocket 3 and rotates in the swing pedal 1 drive crank and rocker mechanism 2; Hinge wheel rotates and drives trailing wheel through minor sprocket 3 by chain 4 transferring power and rotates;
(2) turn to: in the time of need turning to, the turning-bar 7 that swings is realized turning to of wheelchair;
(3) braking: when needing braking, the foot-operated cross bar of going up on the brake unit 8 is realized braking, loose lower limb, cancellation braking.
