Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1 to 4, a kind of manual lifting wheel chair, comprises Wheelchair support 13, seat platform 8 and the backrest 9 with wheel 14, described wheel 14 is provided with brake gear 15; Wheelchair support 13 is fixed with guide post 10 vertically, and described seat platform 8 is sleeved on guide post 10, and can move up and down along guide post 10; Seat platform 8 is connected by revolute pair with backrest 9.
Described manual lifting wheel chair also comprises Manual height part and backrest angle adjustment portion, described Manual height part comprises the handwheel 1 being arranged on Wheelchair support 13 both sides, the handwheel 1 of both sides is fixed on handwheel guide rod 2, and handwheel guide rod 2 is arranged on Wheelchair support 13 by bearing; Handwheel guide rod 2 is fixed with gear 3, and the outer ring of gear 3 is a bit fixedly connected with one end of connecting band 4, and the other end of connecting band 4 and one end of first connecting rod 5 are hinged, and the other end of first connecting rod 5 and the lower end of seat platform 8 are hinged; One end of second connecting rod 6 is connected on handwheel guide rod 2 by revolute pair, and the middle part of the other end and first connecting rod 5 is hinged, and handwheel 1 is provided with locking device 16; Described backrest angle adjustment portion comprises third connecting rod 11 and double leval jib 12, and one end of third connecting rod 11 and the side of Wheelchair support 13 are hinged, and one end of the other end and double leval jib 12 is hinged, and the other end and the backrest 9 of double leval jib 12 are hinged.Described locking device 16 and brake gear 15 all adopt the existing structure of wheelchair.
Be fixed with baffle plate 7 in the lower end of described seat platform 8, first connecting rod 5 realizes being hinged with the lower end of seat platform 8 by being hinged with described baffle plate 7.
