Alloy plastic wheelchair

Abstract

The invention discloses an alloy plastic wheelchair consisting of a wheelchair assembly connected with an armrest, a chair back, a chair pad, front wheels, wheels, a pedal and a brake, wherein, the wheelchair assembly is composed of a whole formed by connecting a left frame and a right frame by folding pieces; the folding pieces are connected into a rotatable whole by a left support pipe and a right support pipe along a pin shaft; bent clamps at vertical ends of the left support pipe and the right support pipe and sliders at two transversal ends are respectively matched with the left frame and the right frame, and the left frame, the right frame, the left support pipe and the right support pipe are manufactured into a hollow pipe frame using alloy plastic with the method of injection molding by one time. The wheelchair has simple structure, does not need joints and accessories and uses few components. The wheelchair can be simply assembled without welding, electroplating and subsequent processing and has the advantages of short production period, high production efficiency, low price and zero environmental pollution; moreover, the wheelchair is made of material with favorable intensity and toughness; the wheel chair is beautiful, light and bright in color and can compare favourably with a metal wheel chair. The alloy plastic wheelchair can be directly recycled after being damaged for a long time of usage, thus having low energy consumption and environment protection.

Description

technical field [0001] The invention relates to a wheelchair for disabled persons or patients who cannot walk, especially an alloy plastic that does not require electric welding, electroplating, has no environmental pollution, is easy to use, light in weight, low in manufacturing cost, foldable, and convenient for storage and transportation. wheelchair. Background technique [0002] Although the patent No. 96241945.1 "wheelchair" also provides a kind of portable wheelchair made of plastics, it is supported by two front seats and two rear seats to support and connect the pipe fittings forming the chair structure, and then use double central parts to connect without welding. Pipe fitting structure, and each part is equipped with upper and lower T-shaped joints, and the upper and lower T-shaped joints are used to fix the components on both sides, that is, the components on both sides pass through the T-shaped joints, and then connect the cross It is made of pipe fittings.
