The strong flexibility of wheelchair operation, returns and has kept away the deficiency that common wheelchair pushes runner to advance using both hands.
But although electric wheelchair can voluntarily drive the direction of advance, most wheelchair all than cumbersome, so
Very inflexible when carrying, the universal space of wheelchair currently on the market is all bigger, needs when mobile by each of wheelchair
Component disassembly carries and completes to need assembled, and such operation is rich normal cumbersome, reduces the practicality energy, is repairing
When it is also very inconvenient, permanent such dismounting also influences the service life of wheelchair, can equally allow user to feel very tired,
Although and common wheelchair is more small and exquisite, be inconvenient to fold, with depositing in use in the presence of being short of, reduce use it is flexible
Property, there is deficiencies, it is not able to satisfy the demand of social development,.
In conclusion in view of the drawbacks of the prior art, it is accordingly required in particular to a kind of lightweight wheelchair skeleton fold mechanism, it is existing to solve
There is the deficiency of technology.
Summary of the invention
It is bigger for wheelchair occupied space in the prior art, and be inconvenient in actual use to fold and weight ratio
It is larger, very big influence is brought again to the daily life of disabled person, the present invention proposes a kind of lightweight wheelchair skeleton fold mechanism, if
Meter is novel, portable construction, and the frame design of wheelchair is become foldable shape, the weight of wheelchair is reduced, enhances practical performance,
Solve the defect of the prior art.
To achieve the goals above, technical scheme is as follows:
A kind of lightweight wheelchair skeleton fold mechanism: the material that the skeleton uses is light alloy, and skeleton is by back bracket, seat
Pad support, supporting leg composition, by convergence piece, back bracket passes through overturning axis connection rank for the connection of back bracket and cushion bracket
Fitting, convergence piece by rotation screw connection cushion bracket, draw by the folding that the rotation screw linking of convergence piece lower end setting interlocks
Bar, the end face of folding pull rod are rotatablely connected the pulling pin inside pin shaft, pass through the fixed rotating bolt connection in surface between cushion bracket
There is glued component, glued component is made of two groups of folding roof beams structure, folds hack lever composition of the roof beam structure by two intersections, every group of folding
The infall of roof beam structure and fold and be provided with couple axle at docking between roof beam structure, glued component, back bracket, cushion bracket,
The interlinked mechanism that supporting leg, convergence piece, pulling pin composition skeleton fold.
Further, the shape of the convergence piece is L-shape.
Further, the shape folded between roof beam structure is in X shape, and the hack lever for folding roof beam structure is in bending-like.
Further, the side of the cushion bracket is provided with bull wheel mounting plate.
Further, the top surface of the back bracket is provided with the pushing hands of bending.
Further, the cushion bracket is fixedly connected by connecting arc and supporting leg.
The beneficial effects of the present invention are: this product structure is simple, portable construction is easy to make, facilitates the elderly or residual
The use of disease people, wheelchair use fold design, fold and open controlled by pulling pin, improve wheelchair use it is flexible
Performance, and the volume of wheelchair is smaller, when carrying, keeps wheelchair the space occupied less, and organoleptic properties are good, and design is new
Grain husk is a kind of good innovation scheme, is very promising for marketing..
