Abstract
The invention discloses a wheelchair convenient for stair climbing and suburb cross-country, which belongs to the technical field of wheelchairs and mainly comprises wheels, a swing frame, a converter, a wheel groove frame, a suspension frame, a seat and the like. The four-wheel wheelchair with the large wheelbase and the small wheelbase at the two sides has more advantages in climbing stairs and cross-country than a wheelchair with the same wheelbase. The wheelchair avoids the up-and-down pitching of the front and the back when climbing stairs, and when each single wheel is lifted, one side of the wheelchair is lifted by 1/2 with the single wheel lifted, when the front two wheels are lifted, the single wheel with the weight is smaller than the whole mass 1/4, and when the rear two wheels with the single wheel with the weight is slightly larger than the whole mass 1/4. The wheelchair with the structure does not jolt when going upstairs or downstairs, only slightly fluctuates left and right, and the wheels are light, convenient, fast and labor-saving when climbing stairs.
Description
Technical field
The present invention relates to wheelchair technical field, is more particularly a kind ofly be convenient to the cross-country wheelchair of stair climbing and countryside.
Background technology
Present urban family major part all stays in community upstairs, a lot of building does not have elevator, the old man of walking disorder or people with disability are above downstairs with regard to inconvenience very, they expect that outdoor activities are just very difficult, realized by the back of the body, embrace etc. by other people often, want just more to have bothered to countryside activity, so often limit their activity, be unfavorable for their health, reduce their quality of life.

The object of the invention is to be achieved through the following technical solutions:
A kind ofly be convenient to the cross-country wheelchair of stair climbing and countryside, comprise wheel-chair beam, it is characterized in that: described wheel-chair beam is for left, right two axle sleeves, left, all semiaxis is installed in right two axle sleeves, by screw, transducer is installed between two axle sleeves, the outer one end of two semiaxis is all installed with rocking carrier, the length of two rocking carriers is different, the inner one end of two semiaxis is installed on the switch, the rear and front end of rocking carrier is all provided with axletree, axletree is provided with wheel, the wheelspan of wheelspan and the right two wheels of two wheels in the left side is different, left, right two axle sleeves are all installed with wheel truss, wheel truss is provided with mobile race, left, in right two mobile races, two movable pulleys are all installed, movable pulley is provided with moving shaft, two moving shafts of the same side are provided with A type hanger bracket, the top of A type hanger bracket is provided with suspension minor axis, left, seat is hung with between right two suspension minor axises, seat is provided with rocking rod controller.
Described be a kind ofly convenient to the cross-country wheelchair of stair climbing and countryside, it is characterized in that: described transducer is made up of tooth housing, conversion gear axle, semiaxis, half axle gear and conversion tooth, the two ends, left and right of tooth housing are all provided with semiaxis, the part that semiaxis is positioned at tooth housing is provided with half axle gear, tooth housing is provided with conversion gear axle, the two ends of conversion gear axle are all provided with conversion tooth.
The invention has the advantages that:
The both sides provided by the invention wheel bases wheelchair that large four-wheel wheelchair little is on one side equally larger than wheelspan on one side, climb building and cross-country on have more superiority.The front and back that it avoid when climbing building pitch, and during each single-wheel rising, wheelchair side raises 1/2 of just single-wheel rising, and be subject to heavily single-wheel to be less than whole quality 1/4 when front two-wheeled raises, rear two-wheeled single-wheel is by heavy slightly larger than whole quality 1/4.Do not jolt during the wheelchair stair activity of this spline structure, only can left and right fluctuation slightly, wheel stair climbing light and fast is laborsaving.
