Fig. 1 is the overall structure sketch map of this utility model embodiment;
Fig. 2 is the structural representation of the fork part of this utility model embodiment;
Fig. 3 is the structural representation of the brake bar part of this utility model embodiment.
The specific embodiment
As shown in Figure 1, wheelchair walking mechanism of the present utility model includes the fork 2 that is positioned at wheel 1 inboard, and the lower end sky of fork 2 is enclosed within on the axletree 11.
As shown in Figure 2, have a walking rod 3 and fork 2 to intersect, walking rod and fork are hinged at its infall; The epimere of walking rod is near the fork epimere, and the hypomere of walking rod is positioned at wheel 1 outside; Be respectively arranged with outer fixture block 31 and internal clamping block 21 on the walking rod of both sides, vehicle wheel inside and outside and the fork.Like this as long as the epimere of fork 2 and walking rod 3 promptly makes them mutually close, just can make the outer fixture block 31 of hypomere and internal clamping block 21 mutually near and clamp the wheel body of wheel 1, promote fork more at this moment and walking rod can make wheel and fork together rotate.
Between walking rod 3 and fork 2, be connected with the back-moving spring 22 that can make walking rod and fork hypomere get back to the position that is separated.
Described internal clamping block 21 and outer fixture block 31 are respectively cylindric, they respectively sky be enclosed within fork 2 hypomeres and walking rod 3 hypomeres; The outer surface of outer fixture block 31 is provided with teeth groove longitudinally, the fixture block inboard is provided with a rotation preventive mechanism 23 that is installed on the fork outside simultaneously, the front end of rotation preventive mechanism is a spline piece 231, the outer surface of spline piece have with outer fixture block the tooth that matches of teeth groove, spline piece rear end is pressed with spring.
In the process of walking, if unclamp the epimere of fork 2 and walking rod 3, when inside and outside fixture block is separated, inside and outside fixture block can with the vehicle wheel bulk phase to moving, even at this moment the wheel wheel body to a side certain deviation is arranged and with internal clamping block 21 or outside fixture block 31 contact, also will can not cause obstruction owing to the rotation of inside and outside fixture block to relatively moving between inside and outside fixture block and the wheel wheel body; On the contrary, if firmly grasp the epimere of fork and walking rod, inside and outside fixture block mutually near and clamp the wheel body of wheel 1, outer fixture block 31 is owing to contacting with spline piece 231 and can't rotating, at this moment can't relatively move between inside and outside fixture block and the wheel wheel body, promote fork 2 this moment just can make the wheel wheel body along with fork and walking rod together rotate, and realizes walking.
On the said structure basis, on fork 2, also be hinged with a brake activation lever 4, the brake activation lever epimere is mutually close with the epimere of fork 2 and walking rod 3.As shown in Figure 3, on the vehicle frame of wheel inboard, be installed with an inside brake bar 5, be hinged with an outer brake bar 6 on the inside brake bar; The hypomere of inside brake bar and outer brake bar is respectively arranged with inside brake piece 51 and the outer brake block 61 that is positioned at wheel 1 wheel body both sides; Be connected with a braking steel wire 7 between the lower end of above-mentioned brake activation lever 4 and inside brake bar 5 epimeres, trocar sheath 71 two ends of braking steel wire are separately fixed at fork 2 hypomeres and outer brake bar 6 epimeres.
In addition, between inside and outside brake bar, be connected with the brake bar back-moving spring 52 that can make inside and outside brake block clamping wheel.
Described inside brake piece 51 and outer brake block 61 are respectively cylindric, they respectively sky be enclosed within on inside brake bar 5 and the outer brake bar 6, outer brake block outer surface also is provided with teeth groove longitudinally, brake block 61 inboards are provided with a brake block rotation preventive mechanism 53 that is installed on the inside brake bar 5 outside simultaneously, brake block rotation preventive mechanism front end is a brake block spline piece 531, the outer surface of brake block spline piece has the tooth that matches with the teeth groove of outer brake block 61, and brake block spline piece rear end is pressed with spring.
In the process of walking;
When the epimere that unclamps fork 2 and walking rod 3, inside and outside fixture block can with the vehicle wheel bulk phase to moving, this moment, brake activation lever 4 was also released, also released by inside brake bar 5 and outer brake bar 6 that braking steel wire 7 and trocar sheath 71 are connected with brake activation lever and fork, inside and outside brake block is clamped the wheel wheel body under the effect of spring force, the wheel wheel body can not rotated, and this can prevent that wheelchair falls back when fork and carriage release lever unclamp when going up a slope;
When the epimere of firmly grasping fork and walking rod, inside and outside fixture block mutually near and clamp the wheel wheel body, at this moment promote fork and wheel 1 wheel body is together rotated along with fork 2 and realize the walking, because this moment, brake activation lever 4 was also together firmly grasped, by braking steel wire 7 and trocar sheath 71, inside and outside brake block is separated, thereby can hinder wheel and rotate.At this moment, though the wheel wheel body to a side certain deviation is arranged and with the inside brake piece or outside brake block contact, will can not cause obstruction owing to the rotation of inside and outside brake block to this relatively moving yet.
