Description
Technical field
The present invention relates to a kind of manual portable wheelchair lifting device, belong to the civilian technology field.
Background technology
People with disability colony is an important colony of social concerns, and wheelchair then is the important branch in the machinery of helping the disabled, and for the people of lower limb disability, wheelchair is indispensable walking-replacing tool.Design has hommization, low price, and portable wheelchair can improve people with disability user's self-care ability effectively.
Wheelchair is divided into common wheelchair and specifical wheelchair two big classes usually.Common wheelchair generally is made up of four parts such as chair frame, wheel (big wheel and trundle), brake gear and seat lean on, comprises corresponding hand rim, tire, seat back arm or arm holder, foot holder and lower limb holder etc.; Specifical wheelchair derives from from common wheelchair according to wheelchair user's limb function and application target, and commonly used have fixed wheelchair, foldable wheelchair, stand-up wheelchair, the formula of lying wheelchair, one-sided driving wheelchair, electrodynamic type wheelchair, sports with wheelchair etc.At present, what account for that the domestic consumer of larger proportion needs is a kind of convenience, cheap, can expand the wheelchair of certain self-care function simultaneously again, as liftable etc., does not have this respect function and wheelchair that can be portable but still have at present.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of manual portable wheelchair with liftable function, makes it can satisfy the requirement of people with disability to independent action, improves its self-care ability.
In order to realize above purpose, manual portable wheelchair lifting device of the present invention is by the downslide channel bar, the seat front baffle, side lifting fork group, the upper hopper chute bar, the seat afterframe, plane lifting fork group, the elevating screw assembly, locating shaft, lifting fork group connecting pin, parts such as location axle bed are formed, the elevating screw assembly also comprises lifting handle, elevating screw, the lead screw shaft bearing, lifting nut and rocking handle, wherein, the lead screw shaft bearing is fixedly mounted on the seat afterframe, lifting nut is fixedly mounted on the seat front baffle, upper hopper chute bar and downslide channel bar connect with the side lifting fork group of both sides by each 4 hinge of every side respectively, plane lifting fork group connects with seat front baffle and seat afterframe respectively by 4 place's hinges, 4 location axle beds are fixedly mounted on respectively on the side lifting fork group of both sides, seat front baffle and seat afterframe by locating shaft respectively activity be placed in the axle bed of both sides location.
In addition, in 4 place's hinge-coupled of the side lifting fork group of every side and upper hopper chute bar and downslide channel bar, 2 places are elongated slot or the movable connection of slide block; In 4 place's hinges that plane lifting fork group connects with seat front baffle and seat afterframe, 2 places are elongated slot or the movable connection of slide block; Plane lifting fork group is arranged on a side of wheelchair symmetrical centre.
Manual portable wheelchair lifting device involved in the present invention carries out human oriented design at this demand of seats liftable, user can drive the lifting nut that is fixed on the seat front baffle by rocking handle rotation and lifting leading screw as required and do rectilinear motion, and drive that the seat front baffle moves forward and backward and do the folding and unfolding campaign by the side lifting fork group that locating shaft drives both sides, this motion impels seat front baffle and seat afterframe to move up and down again, thereby realizes the elevating function of seats.The present invention can change desired adjustable height by the conventional design maneuver of offside lifting fork group fork arm size and upper hopper chute bar, downslide channel bar elongated slot size or slide block moving section etc., therefore, can guarantee easily that user approximates the height that the normal person stands at the height of wheelchair rising recoil on the seat, thereby improve people with disability's self care ability; In addition, this device still has portable characteristics.
Description of drawings
The specific embodiment below in conjunction with Fig. 1, Fig. 2 and Fig. 3 is described in further detail a kind of manual portable wheelchair lifting device that foundation the present invention proposes.
Fig. 1 is the sketch of facing of a kind of manual portable wheelchair lifting device of proposing according to the present invention.
Fig. 2 is the diagrammatic top view of a kind of manual portable wheelchair lifting device of proposition according to the present invention.
Fig. 3 is the horizontal diagrammatic cross-sectional view of a kind of manual portable wheelchair lifting device of proposition according to the present invention.
The specific embodiment
A kind of manual portable wheelchair lifting device of present embodiment such as Fig. 1, Fig. 2 and shown in Figure 3, mainly be made up of parts such as downslide channel bar 1, seat front baffle 4, side lifting fork group 5, upper hopper chute bar 6, seat afterframe 8, plane lifting fork group 9, elevating screw assembly 10, locating shaft 11, lifting fork group connecting pin 13, location axle beds 17, elevating screw assembly 10 also comprises lifting handle 2, elevating screw 3, lead screw shaft bearing 7, lifting nut 14, rocking handle 16 etc.
Said lead screw shaft bearing 7 is fixedly mounted on the seat afterframe 8, lifting nut 14 is fixedly mounted on the seat front baffle 4, upper hopper chute bar 6 and downslide channel bar 1 connect with the side lifting fork group 5 of both sides by each 4 hinge of every side respectively, plane lifting fork group 9 connects with seat front baffle 4 and seat afterframe 8 respectively by 4 place's hinges, 4 location axle beds 17 are fixedly mounted on respectively on the side lifting fork group 5 of both sides, seat front baffle 4 and seat afterframe 8 by locating shaft 11 respectively activity be placed in the axle bed 17 of both sides location, in 4 place's hinge-coupled of the side lifting fork group 5 of every side and upper hopper chute bar 6 and downslide channel bar 1, it is that longitudinal connects that 2 places are arranged, perhaps also can adopt the movable connection of slide block, and in 4 place's hinges that plane lifting fork group 9 connects with seat front baffle 4 and seat afterframe 8, it is that longitudinal connects that 2 places are also arranged, perhaps also can adopt the movable connection of slide block, like this, when by rocking handle rotation and lifting leading screw, the side lifting fork group that just can realize moving forward and backward of seat front baffle and drive both sides is done the folding and unfolding campaign, and drive seat front baffles and seat afterframe through location axle bed 17 and locating shaft 11 and do and move up and down, thereby realize the lifting of seats.
Said plane lifting fork group 9 is arranged on a side of wheelchair symmetrical centre, so just can be convenient to make portable wheel chair to realize folder function.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
