Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of wheel-chair.
Background technology
Along with China resident slowly steps into aging, handicapped person increases, the people on the wheelchair of unmanned nursing especially at one's side, and the up and down wheelchair is dangerous, inconvenient.Even there is the guardian to assist, also suitable effort, furthermore embrace or lift all and might cause secondary injury to them.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple in structure, handling safety is provided, facilitates the user wheel-chair of up and down voluntarily.
This utility model wheel-chair comprises handlebar, backrest, medicated cushion, body installation, driving device, braking mechanism, and described body installation comprises two vehicle frames, and described vehicle frame is C type and epimere part of horizontal, connects by articulated linkage between described vehicle frame; Described driving device comprises walking mechanism and power transmission shaft, described power transmission shaft is fixedly connected with the vertical part of vehicle frame, be fixed with slideway between described power transmission shaft and vehicle frame, the lower end of described articulated linkage is fixedly connected with the lower end of slideway, and the upper end of described articulated linkage and the upper end of slideway are slidably connected; Described power transmission shaft lower end is provided with drivewheel, and described walking mechanism is connected with drivewheel by power transmission shaft, and the rear end of described vehicle frame hypomere part is provided with directive wheel.
Described vehicle frame epimere partly is connected with two or more take off and landing strip, and described take off and landing strip is connected with medicated cushion by safety belt buckle, and described backrest is located at the rear end of vehicle frame epimere part and can opens to a side.
Described take off and landing strip is controlled by the elevating mechanism of vehicle frame epimere part knee.
Described walking mechanism is provided with front brake mechanism, and described handlebar lower end is provided with rear braking mechanism.
Described walking mechanism is provided with change speed gear box.
Described walking mechanism and
/Or elevating mechanism Motor Drive.
Put by sliding sleeve outside described power transmission shaft and be fixed with legging, pedal is fixed on legging by rotating shaft.
This utility model compared with prior art has advantages of simple in structure, handling safety, easy to use.
Description of drawings
Fig. 1 is the structural representation of this utility model wheel-chair;
Fig. 2 is the user mode reference diagram of wheel-chair shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is elaborated:
As shown in Figure 1 and Figure 2: 1, vehicle frame, 2, drivewheel, 3, directive wheel, 4, walking mechanism, 5, elevating mechanism, 6, front brake mechanism, 7, power transmission shaft, 8, legging, 9, pedal, 10, backrest, 11, medicated cushion 12, safety belt buckle, 13, take off and landing strip, 14, rear braking mechanism, 15, handlebar, 16, articulated linkage, 17, slideway, 18, change speed gear box.
It is made of vehicle frame, drivewheel, directive wheel, walking mechanism, elevating mechanism, front brake mechanism, power transmission shaft, legging, pedal, backrest, medicated cushion, safety belt buckle, take off and landing strip, rear braking mechanism, handlebar, articulated linkage, slideway, change speed gear box.Wherein vehicle frame is bent by whole tubing and forms, and making is simple and bearing capacity is strong.By the operation kinetic energy process certain proportion speed change of walking mechanism with user, pass to drivewheel by power transmission shaft; The walking mechanism counter-rotating, the wheelchair drivewheel produces speed difference, drives the directive wheel follow-up steering; Medicated cushion can break away from safety belt buckle makes it separate with wheelchair, and take off and landing strip is driven by elevating mechanism, shakes clockwise or counterclockwise the rocking handle of elevating mechanism, makes take off and landing strip increase or descends.Backrest can be opened to a side, facilitates user wheelchair up and down.On walking mechanism with front brake mechanism, but speed and Parking that user control wheel chair is advanced; The handlebar lower end is provided with rear braking mechanism.Drivewheel is positioned at the place ahead of vehicle frame, and directive wheel is positioned at the rear of vehicle frame.Advantage is, drivewheel is front, and trafficability characteristic is better than wheelchair rear driving wheel in the past, runs into small stair or pitting when hollow, and drivewheel is that diameter has greatly driving force as usual to pass through in cause.Wheelchair directive wheel is in the past front running into small stair or pitting when hollow, can be little because of the directive wheel diameter, without driving force, easily turn to etc. former thereby can't normally pass through.Walking mechanism is with change speed gear box, can select the gear that is fit to according to the size of the road surface situation of walking and the gradient, allows drivewheel have enough driving torsion and drives wheelchair it is normally passed through.This wheelchair walking mechanism and elevating mechanism also can be selected Motor Drive, become electric wheelchair, can allow user and operator operate more easily.Pedal is fixed on legging by rotating shaft, can do folded inward motion segment save space.Legging is fixed on the outer of power transmission shaft by sliding sleeve and puts, and can slide up and down to allow user select to fix after optimum height.Two vehicle frames are connected with slideway by articulated linkage, and the lower end of articulated linkage and the lower end of slideway are fixed by pivot pin, and the upper end is for being slidably connected.Take off medicated cushion, after opening the locking of backrest, vehicle frame just can be connected and be folded merging by articulated linkage.
This wheel-chair is put up the C font, can allow easily the directive wheel of wheelchair stretch under the sick bed of user or under seat.Then medicated cushion is placed under the buttocks of user and adjusts suitable position, then four safety belt buckles on four take off and landing strip are connected locking with four dead bolts on medicated cushion.After checking locking firmly, two rocking handles while up time directions of elevating mechanism are shaken, user is sitting in will be mentioned by elevating mechanism on medicated cushion and leaves bed surface like this, and the inverse time direction is shaken the rocking handle of elevating mechanism, and medicated cushion will drop on bed surface down.Can according to the rocking handle of practical situation rotary lifting mechanism, adjust up and down the medicated cushion height after leaving bed surface.So just can accomplish this wheelchair up and down of making user oneself more easy and convenient.Take away medicated cushion and become a walking rehabilitation car, allow user hold the both sides vehicle frame, stand on the wheelchair center, can allow like this user safety exercise, correct and walk.If there is the guardian to operate this wheelchair, method is same easily simple.
