When downward promotion handle turns clockwise handle, handle pulling binding moves up, binding drives braking vane and is rotated counterclockwise also compression retracteding position spring, thereby the front end of braking vane is pressed in prevention wheel movement on the wheel, snaps between rear side supporting leg and the handle rubber fixture block handle is locked again; Take out the rubber fixture block, handle rotates counterclockwise gets back to initial position, braking vane at return spring (33) thus effect under the separating wheel that turns clockwise.
The left and right sides of above-mentioned wheelchair frame (1) is provided with bar, the front end of left side bar (41) is equipped with handwheel (5), the axis horizontal of described handwheel (5) and perpendicular to described left bar (41), this handwheel (5) circumferentially be provided with the first training tooth (51) parallel with handwheel (5) axis; The front end of right bar (42) is equipped with horizontal rotating disc (6), has the hole (61) parallel with rotating disk (6) axis on the rotating disk (6), and the front portion of right bar (42) is provided with the helical second training tooth (42a).Point and drive dial rotation in the hole of stretching on the rotating disk, be used for movable hands arm; The second training tooth of the first training tooth of handwheel, right bar is to design according to the stairstepping of pointing, and plays the effect of training finger.
The place ahead of above-mentioned wheelchair frame (1) also is provided with pedal structure (7), when user is settled down, can be placed on both feet on the pedal of pedal structure promptly movable ankle, also movable knee.
Above-mentioned handle (15) is by handlebar stem (15a) and be enclosed within handlebar stem (15a) rear end glove (15b) are formed described rubber fixture block (35) and one-body molded glove (15b); A glove is set, increases the comfortableness that grips, the rubber fixture block with one-body molded glove, is convenient to processing and manufacturing, reduced number of spare parts simultaneously, be convenient to management.
The present invention has improved braking mechanism on the basis of common wheelchair, the processing simple in structure, safe and reliable, easy of its braking mechanism, cost are low; Increase the function of training limbs simultaneously, be fit to wounded or disabled patient or handicapped auxiliary walking of old people and rehabilitation training, can satisfy the multiple demand of rehabilitation training.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is the scheme of installation of binding in handle among the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
A kind of wheelchair with the safety shut-down function as shown in Figure 1 is made up of wheelchair frame 1, four rotating wheels 2 and the braking mechanism that is symmetricly set on wheelchair frame 1 left and right sides.Wheelchair frame 1 is made of two front side supporting legs 11, two rear side supporting legs 12, backrest 13, seat board 14 and two handles 15.The upper end of front side supporting leg 11 flushes with seat board 14, and the upper end of rear side supporting leg 12 flushes with the upper end of backrest 13.Four wheels 2 are installed in the below and the rectangular layout of wheelchair frame 1, and the wheel 2 of close two rear side supporting leg 12 belows is main wheel.The upper end of the front end of handle 15 and rear side supporting leg 12 is hinged, and handle 15 can rotate up and down around jointed shaft 8.Braking mechanism is made of braking vane 31, binding 32, return spring 33, spring limited block 34 and rubber fixture block 35, and two main wheels are respectively by a braking mechanism braking.
As Fig. 1-3, the middle part of braking vane 31 is hinged on the bottom of rear side supporting leg 12 and is positioned at the top of wheel 2, spring limited block 34 is fixed on the rear side supporting leg 12 and is positioned at the top of braking vane 31, and rubber fixture block 35 hangs on the glove 15b, and rubber fixture block 35 is with one-body molded glove 15b.Handle 15 is formed by handlebar stem 15a with glove 15b, and the upper end of the front end of handlebar stem 15a and rear side supporting leg 12 is hinged, and glove 15b is enclosed within handlebar stem 15a rear end.Under the situation of handle 15 cover not with handles 15b, rubber fixture block 35 also can directly hang on the handle 15 by a rope.
The upper end of binding 32 is fixed in the handle 15, and the lower end of this binding 32 is passed the rear end that is fixed on braking vane 31 behind spring limited block 34 and the return spring 33 successively.The upper end of return spring 33 is against on the spring limited block 34, and its lower end is pressed on the braking vane 31.When wheel 2 rolled, handle 15 was perpendicular to rear side supporting leg 12, and the front end of braking vane 31 upwards lifts the back and breaks away from main wheel.
When needing brake, promote handle 15 downwards, handle 15 turns clockwise, handle 15 pulling bindings 32 move up, binding 32 drives braking vane 31 and is rotated counterclockwise also compression retracteding position spring 33, thereby the front end of braking vane 31 is pressed in and stops wheel 2 motions on the wheel 2, rubber fixture block 35 is snapped between rear side supporting leg 12 and the handle 15 handle 15 is locked again; In the time of need advancing, take out rubber fixture block 35, handle 15 rotates counterclockwise gets back to initial position, the separating wheel 2 thereby braking vane 31 turns clockwise under the effect of return spring 33.
As shown in Figure 1, the left and right sides of wheelchair frame 1 is provided with bar, and the front end of left bar 41 is equipped with handwheel 5, the axis horizontal of handwheel 5 and perpendicular to left bar 41, this handwheel 5 circumferentially be provided with the first training tooth 51 parallel with handwheel 5 axis; The front end of right bar 42 is equipped with horizontal rotating disc 6, has the hole 61 parallel with rotating disk 6 axis on the rotating disk 6, and the front portion of right bar 42 is provided with the helical second training tooth 42a.In addition, the place ahead of wheelchair frame 1 is provided with pedal structure 7, and pedal structure 7 comprises pedal 71 and pedal frame 72, and the lower end of pedal frame 72 is fixed on two connecting rods between the front vehicle wheel 2.
