Anti-dumping safe wheelchair

Abstract

The invention discloses an anti-dumping safe wheelchair. The anti-dumping safe wheelchair comprises piston rods, cylinders, return springs, hinges, communicating air pipes, pneumatic valve control switches, a seat body and a wheel train chassis; the piston rods are arranged inside the cylinders; the upper ends of the cylinders are connected by the communicating air pipes; the tops of the cylindersare fixedly connected with the seat body by threads; the pneumatic valve control switches are connected with the communicating air pipes, and are arranged on handrails of the seat body; the bottom ends of the piston rods are connected with the wheel train chassis by the hinges; one ends of the return springs are connected with the hinges while the other ends of the return springs are connected with the seat body; the numbers of the piston rods, the cylinders and the hinges are all four; the hinges are connected with wheel train chassis by hinge supports; and the hinge supports are connected with the wheel train chassis by threads. The anti-dumping safe wheelchair is environmentally friendly, economical, affordable, simple to operate, high in practicability and conducive to promoted use.

Description

technical field [0001] The invention relates to the technical field of wheelchair application, in particular to an anti-tilt safety wheelchair. Background technique [0002] When an ordinary wheelchair goes up and down a slope, it will inevitably cause the occupant to lean forward or backward, and the center of gravity of the occupant will change, which will have a negative impact on its comfort and greatly reduce its safety; Using a controller for control reduces the reliability of the electronic circuit and increases power consumption, which puts additional requirements on the energy supply and storage of the device. Contents of the invention [0003] It is difficult for the prior art to meet people's needs. In order to solve the above-mentioned problems, the present invention proposes an anti-tilt safety wheelchair. [0004] In order to achieve this technical purpose, the technical solution adopted by the present invention is: an anti-tilt safety wheelchair, including ...
