Description

A kind of lightweight wheelchair skeleton fold mechanism

Technical field

The utility model relates to the walking-replacing tools of disabled person a kind of, more particularly to a kind of lightweight wheelchair skeleton folding machine Structure.

Background technique

With the development and the improvement of people's living standards of social and welfare services, disabled person has more and more used health Multiple wheelchair, wheelchair eliminate thus at lower limb physical disabilities and the indispensable walking-replacing tool of old and frail people Treatment personnel's is arduous, facilitates transfer in hospital, can facilitate its voluntarily movable needs, existing market in real life On common wheelchair by wheelchair frame, wheel, brake gear and seat against four parts and form, and it is energy that electric wheelchair, which is by battery, Source, the power wheel Wheel-chair of electronic device control driving, user can voluntarily drive the advance of wheel-chair by control device, increase 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, are 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.

Utility model content

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 utility model proposes a kind of lightweight wheelchair skeleton folding machines The frame design of wheelchair is become foldable shape, reduces the weight of wheelchair, enhance practicability by structure, novel in design, portable construction Can, solve the defect of the prior art.

To achieve the goals above, the technical solution of the utility model 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 utility model are: this product structure is simple, portable construction is easy to make, facilitate the elderly or It is the use of disabled person, wheelchair uses fold design, folds and opening is controlled by pulling pin, improve what wheelchair used Flexible performance, and the volume of wheelchair is smaller, when carrying, keeps wheelchair the space occupied less, and organoleptic properties are good, if Meter is novel, is a kind of good innovation scheme, is very promising for marketing..

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of lightweight wheelchair skeleton fold mechanism: the material that the skeleton uses is lightweight conjunction Gold, skeleton are made of back bracket 100, cushion bracket 110, supporting leg 160, the connection of back bracket 100 and cushion bracket 110 By convergence piece 120, back bracket 100 is sat by overturning axis connection convergence piece 120, convergence piece 120 by rotation screw connection Pad support 110, the folding pull rod 130 that the rotation screw linking of 120 lower end of convergence piece setting interlocks, the end face of folding pull rod 130 The pulling pin 170 being rotatablely connected inside pin shaft 140 is connected with glue by surface fixation rotating bolt 200 between cushion bracket 110 Seaming element 180, glued component 180 are made of two groups of folding roof beams structure, fold hack lever composition of the roof beam structure by two intersections, every group of folding Couple axle 190, glued component 180, back bracket are provided at docking between the infall and folding roof beam structure of stoplog frame 100, cushion bracket 110, supporting leg 160, convergence piece 120, pulling pin 170 form the interlinked mechanism that skeleton folds.
