Abstract
The invention relates to a stair-climbing wheelchair which comprises handle levers, a guideway rail and a pulley. The guideway fixes and connects the handle levers. The pulley is installed on the guideway. An upper movable pole support is connected with a pulley spindle in the pulley fixedly. A handle is installed on the upper movable pole support fixedly. The other end of the upper movable pole support is welded with an upper fixed shaft. An upper chain wheel is connected with the upper fixed shaft in a rotary way. A fixed plate is connected with the upper fixed shaft in a rotary way. A connection component is connected between the fixed plate and a lower movable pole support fixedly. A lower fixed shaft is installed on the lower movable pole support fixedly. The lower fixed shaft is connected with a lower chain wheel in a rotary way. The other end of the lower movable pole support is connected with the guideway in a rotary way. A tension spring is installed at a connection end of the lower movable pole support and the guideway. A track is assembled between two chain wheels. The upper half cavity of the connection component is filled with a pin which is fixed with a spring, and a slide bar presses against the spring and is connected with the fixed plate fixedly. The stair-climbing wheelchair has simple structure, can go upstairs and downstairs easily and is convenient for using.
Description
Technical field:
The present invention relates to wheelchair, particularly a kind of stair-climbing wheel chair.
Background technology:
When the wheelchair that uses is gone downstairs on they need now, the people who takes wheelchair will leave wheelchair, and then wheelchair is carried upstairs, and such carrying just brings a lot of inconvenience to user, when using the upper and lower building of wheelchair, just seem bothersome, require great effort, reduced the service efficiency of wheelchair.
Summary of the invention:
The objective of the invention is to design a kind of stair-climbing wheel chair easily of going up downstairs.Technical scheme of the present invention is, a kind of stair-climbing wheel chair, it comprises handlebar stem, guide rail, pulley, it is characterized in that: guide rail is fixedlyed connected with handlebar stem, pulley is contained on the guide rail, last movable branching rod is fixedlyed connected with the pulley spindle in the pulley, is installed with handle on the last movable branching rod, and the other end of last movable branching rod is welded with fixed axis, upper sprocket wheel and last fixed axis are rotationally connected, fixing head and last fixed axis are rotationally connected, and are fixedly connected with a connector between fixing head and the following movable branching rod, are installed with down fixed axis on the following movable branching rod, following fixed axis and lower sprocket are rotationally connected, the following movable branching rod other end and guide rail are rotationally connected, and the link of infra movable branching rod and guide rail is equipped with tension spring, are equipped with crawler belt between two sprocket wheels.In the chamber of the first half of connector pin is housed, is fixed with spring on the pin, be pressed with sliding bar on the spring, sliding bar is fixedlyed connected with fixing head.Of the present invention simple in structure, wheelchair can be gone up downstairs very easily, and is easy to use.
Description of drawings:
Fig. 1 is the structural representation that the present invention climbs the building device, and Fig. 2 is Fig. 1 right side view, and Fig. 3 is a structural representation of the present invention.
The specific embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail, the present invention, it comprises handlebar stem 1, guide rail 2, pulley 14, guide rail is fixedlyed connected with handlebar stem, pulley is contained on the guide rail, last movable branching rod 3 is fixedlyed connected with the pulley spindle 18 in the pulley, and handle 15 is installed on the last movable branching rod, and the other end of last movable branching rod is welded with fixed axis 16, upper sprocket wheel 4 is rotationally connected with last fixed axis, fixing head 5 is rotationally connected with last fixed axis, is fixedly connected with a connector 9 between fixing head and the following movable branching rod 12, is installed with down fixed axis 17 on the following movable branching rod, following fixed axis and lower sprocket 11 are rotationally connected, the following movable branching rod other end and guide rail are rotationally connected, and the link of infra movable branching rod and guide rail is equipped with between 13, two sprocket wheels of tension spring and is equipped with crawler belt 10.Pin 8 is housed in the chamber of the first half of connector, is fixed with spring 7 on the pin, be pressed with sliding bar 6 on the spring, sliding bar is fixedlyed connected with fixing head.But a present invention also side of infra fixed axis is equipped with accumulator, micromachine or torque dupler.Trailing wheel 19 of the present invention also can be to be fixedly mounted on the trailing wheel slide block 20, and the trailing wheel slide block is assemblied on the trailing wheel guide rail 21, and trailing wheel can be with the moving of slide block like this, and move forward and backward along car body.Handlebar stem of the present invention can be arranged to sleeve structure, can shrink elongation.The present invention is when needs are climbed the building like this, and the trailing wheel of wheelchair is moved to the front-wheel direction, and user is held handlebar stem, and then with crawler belt face contact stair, drags wheelchair and climbs and go upstairs, and is very convenient.When last downstairs finish using after; pack up handlebar stem; again handle is spurred downwards along guide rail; go up then movable branching rod move downward drive upper sprocket wheel and fixing head close to guide rail; following movable branching rod makes whole climbing device to be taken in the containment vessel by the pulling of the pulling force of tension spring, the trailing wheel of wheelchair is moved backward adjust to suitable position at last; do not influence the use of wheelchair on the level land, do not influence the attractive in appearance of wheelchair yet.The present invention is simple in structure, easy to use, can go up downstairs easily.
