Described Manual height part includes the handwheel being arranged on Wheelchair support both sides, and the handwheel of both sides is fixed on handwheel guide rod,
Handwheel guide rod is arranged on Wheelchair support by bearing；Handwheel guide rod is fixed with gear, the outer ring of gear a little be connected band
One end fixing connect, one end of the other end and first connecting rod that connect band is hinged, the other end of first connecting rod and seat platform
Lower end be hinged；One end of second connecting rod is connected on handwheel guide rod by revolute pair, the middle part phase of the other end and first connecting rod
Hinged, handwheel is provided with locking device；
Described backrest angle regulation part includes third connecting rod and fourth link, the side phase of one end of third connecting rod and Wheelchair support
Hinged, the other end is hinged with one end of fourth link, and the other end of fourth link is hinged with backrest.
Being fixed with baffle plate in the lower end of described seat platform, first connecting rod realizes and seat platform by being hinged with described baffle plate
Lower end is hinged.
The gear of described Manual height part, connection band, first connecting rod and second connecting rod are provided with two sets, and two sets are respectively
It is arranged on the both sides of Wheelchair support, and is symmetrical arranged.
The third connecting rod of described backrest angle regulation part and fourth link are provided with two sets, and two sets are separately positioned on Wheelchair support
Both sides, and be symmetrical arranged.
Beneficial effects of the present invention:
1, the manual lifting wheel chair of the present invention only relies on manpower and can realize the rising of seat platform, it is not necessary to electric power, energy-conservation
Environmental protection；
2, controlled due to the lifting degree of the seat platform of the present invention, can also be according to user in addition to the function that can realize going to bed
Demand from Row sum-equal matrix backrest angle so that user is more comfortable；
3, the elderly and the disabled that the manual lifting wheel chair of the present invention can make leg inconvenient is not having household to accompany and attend to the most certainly
Row bunk bed, safety is greatly increased, and its simple in construction, cheap, have higher application value.

Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to 4, a kind of manual lifting wheel chair, including having the Wheelchair support 13 of wheel 14, seat platform
8 and backrest 9, described wheel 14 is provided with brake gear 15；Wheelchair support 13 is fixed with leading vertically
To bar 10, described seat platform 8 is sleeved on guide post 10, and can move up and down along guide post 10；Seat platform 8 with
Backrest 9 is connected by revolute pair.
Described manual lifting wheel chair also includes Manual height part and backrest angle regulation part, described manual regulation height
Degree part includes the handwheel 1 being arranged on Wheelchair support 13 both sides, and the handwheel 1 of both sides is fixed on handwheel guide rod 2, handwheel guide rod
2 are arranged on Wheelchair support 13 by bearing；Handwheel guide rod 2 is fixed with gear 3, the outer ring of gear 3 a little be connected
One end with 4 is fixing to be connected, and connects and is hinged with one end of first connecting rod 5 with the other end of 4, the other end of first connecting rod 5
It is hinged with the lower end of seat platform 8；One end of second connecting rod 6 is connected on handwheel guide rod 2 by revolute pair, the other end with
The middle part of first connecting rod 5 is hinged, and is provided with locking device 16 on handwheel 1；Described backrest angle regulation part includes the 3rd
Connecting rod 11 and fourth link 12, one end of third connecting rod 11 is hinged with the side of Wheelchair support 13, and the other end and the 4th is even
One end of bar 12 is hinged, and the other end of fourth link 12 is hinged with backrest 9.Described locking device 16 and brake gear
15 existing structures all using wheelchair.
Being fixed with baffle plate 7 in the lower end of described seat platform 8, first connecting rod 5 realizes and seat by being hinged with described baffle plate 7
The lower end of chair platform 8 is hinged.
The gear 3 of described Manual height part, connect band 4, first connecting rod 5 and second connecting rod 6 and be provided with two sets, two
Set is separately positioned on the both sides of Wheelchair support 13, and is symmetrical arranged.
