The specific embodiment

In order better to understand the technical solution of the utility model, describe the embodiment that this utility model provides in detail below in conjunction with accompanying drawing.

This utility model embodiment provides a kind of can go up multifunctional wheelchair downstairs, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, this wheelchair comprises: wheelchair the first half 1 and wheelchair the latter half 2, and described wheelchair the first half 1 and wheelchair the latter half 2 interconnect by main trunnion axis 7;

The both sides of described wheelchair the first half 1 are fixed with perpendicular plate 3, and preferred, described perpendicular plate 3 is netted segmental perpendicular plate.Screw is convenient to install in this netted hole.The top of described perpendicular plate 3 is provided with the screw 7 that is used to assemble main trunnion axis 7, a limit of described perpendicular plate 3 is the ogive shape, a curve edges at two ends place of described perpendicular plate 3 is provided with notch 6 respectively, the lower end of described wheelchair the first half 1 fixedly is equiped with rotatable but uncontrollable driven pulley 11, and the below of described wheelchair the first half 1 fixedly is equiped with main chain pulley 17;

The both sides of described wheelchair the latter half 2 are equiped with drivewheel 8, and the colyliform device 9 of the described drivewheel 8 that is used to roll is installed in the outside of described drivewheel 8, and closely is connected with the wheel rim of described drivewheel 8, and described drivewheel 8 is contained on the axle sleeve 10;

The central point of described main trunnion axis 7 fixedly installs the backing pin 13 that is useful on the notch 6 that is buckled in described perpendicular plate 3;

Be set with thick stick handle 4 on described wheelchair the latter half 2, the upper end of described thick stick handle 4 fixedly installs jug, the backing pin 13 that can handle on the thick stick handle 4 moves on described perpendicular plate 3, also by the hinged interface 18 rotating thick stick handles 16 that are connected with, the bending place of described thick stick handle 16 is connected by connecting rod 12 with the corner of described wheelchair the first half 1 described wheelchair the latter half 2.Be equiped with crawler belt 15 on described wheelchair the latter half 2, thick stick handle 16, the main chain pulley 17.

Further among the embodiment, described handle is provided with button 5, can close backing pin 13 by the elastic device in this button 5, simultaneously, also can be by backing pin 13 being ejected from notch 6 by this button 5, wheel turns or crawler belt are rotated, so that this wheelchair moves horizontally by wheel or pass through the crawler belt stair climbing.

When moving horizontally, thick stick handle 4 in the wheelchair lower part 2, backing pin 13 can be by notch 6 snap fit in rear portion on the netted perpendicular plate 3 on the first half 1, in this case, crawler belt can not contact with the ground that not be used to support wheelchair, wheelchair moves by drivewheel 8 and the driven pulley 11 that can not regulate and control, they can freely rotate round vertical wheel, and the turning of this wheelchair is that the power difference of the colyliform device (that is outer rim wheel) 9 of dependence both sides realizes.

In order to change the mode of operation, as switching to the stair activity motion from moving horizontally, user can be easily draws thick stick handle 4 to oneself, with the power of joining that weakens 6 pairs of backing pins 13 of notch (promptly, buckle power), press button 5 simultaneously, backing pin 13 is pulled out from lock-joint 6, after pressing the button thick stick handle 4 is spurred to the direction that pushes away oneself, in backing pin 13 notch forwardly, be lockable, wheelchair relies on crawler belt 15 to move, and the chair of wheelchair (wheelchair the first half 1 and wheelchair the latter half 2) then can be elevated to and be used to support more than the ground of wheelchair.Axle sleeve 10 projectioies of while drivewheel 8, carry out meshing the butt joint with main chain pulley 17, rotate the drivewheel 8 of the colyliform device 9 of wheelchair both sides, need not exert great efforts, user just can advance along stair, the back of wheelchair leans forward when topping bar, and after the step, user is pulled away from oneself with thick stick handle 4 gently, to weaken the gmatjpdumamics of notch to backing pin 13, press button 5 simultaneously, backing pin 13 is pulled out from notch 6, afterwards, move up to the rear end notch of backing pin 13 and pin to perpendicular plate 3, wheelchair relies on wheel turns, and crawler belt 15 is elevated on the drivewheel 8, and the main chain pulley 17 of axle sleeve 10 meetings and crawler belt 15 is separated.

More than a kind of multifunctional wheelchair that can go up downstairs that this utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to this utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
