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

Alloy plastic wheelchair

Technical field

The present invention relates to a kind of wheelchair of using for the people with disability that can not walk or patient, particularly a kind ofly need not electric welding, electroplate non-environmental-pollution, easy to use and in light weight, and low cost of manufacture, collapsible, be convenient to the alloy plastic wheelchair collecting, transport.

Background technology

The patent No. 96241945.1 " wheelchair " is though also provide a kind of easy-to-move wheelchair that becomes with plastic production, it is supported by two front seats and two back seat support and connection form the pipe fitting of Chair structure, the two central parts of reuse need not weld ground connecting tube structure, and upper and lower two T junctions are installed all on each parts, also fix the member of two sides with upper and lower T junction, the member that is two sides passes T junction, connect the cross pipe fitting again and constitute, though in light weightly need not weld, but part assembles trouble more, can't satisfy people's demand.

The patent No. 200620131133.3 " the plasticity wheelchair supporting seat of one hollow, reinforcement " only provides a kind of important composition parts of plastic wheelchair, and the folding supporting seat of wheelchair is X-shaped by two supporting seats intersect to be scratched and to connect, and is supported between the side frames.

Summary of the invention

Technical problem to be solved by this invention is: a kind of alloy plastic wheelchair is provided, main wheelchair assembly only is made up of two big parts, and adopts the injection moulding process one-shot forming to make, and its part does not have follow-up processing less and easily assembles, production efficiency is high and in light weight, production cost is low, environmental protection and energy saving.

The present invention addresses the above problem the technical scheme that is adopted: alloy plastic wheelchair is made up of the wheelchair assembly that is connected with handrail, the chair back, chair cushion, front-wheel, wheel, pedal, brake, described wheelchair assembly is made of through the integral body that folded piece connects into left and right vehicle frame, described folded piece connects into rotating integral body by left and right stay pipe along bearing pin, the described left and right stay pipe directly slide block on climbing on the termination and two horizontal terminations cooperates with left and right vehicle frame respectively, and described left and right vehicle frame and left and right stay pipe are all disposable to be injection molded into alloy plastic.

Described left and right vehicle frame is a symmetry sealing hollow pipe framework, there is handle on the push rod top, there is the axis hole of both ends of the surface projection the lower end, the outer surface of preceding bar, push rod is injected with the left and right backplate of monoblock, and leave cavity between left and right backplate and preceding bar and push rod junction, there are front wheel carrier, running-board bracket and bracing piece in one termination of sheer pole for sticking up pedal on another termination, a shelf is also respectively arranged on preceding bar, the push rod centre position.

Described slide block one end is cylindrical, and the other end is square, and there is the big hemisphere chamber greater than hemisphere square centre.

Described left and right stay pipe is symmetrical T type when sheer pole on the left and right vehicle frame cooperates, also tightly be plugged with cushion block in the straight U-shaped climbing on the termination and be screwed, insert slide block in the transverse ends mouth of pipe and the transverse pipe cunning is joined, be clamped in the ball chamber of slider end on the preceding bar, push rod of left and right vehicle frame.

Compared with prior art, the invention has the advantages that:

One, this Wheelchair structure is simple, need not auxiliary members such as joint and cross pipe fitting, the wheelchair assembly that connects into through intermediary folded piece by left and right symmetric vehicle frame only, and left and right vehicle frame and folded piece are all disposable uses the alloy plastic injection mo(u)lding, part does not have welding less, need not follow-up rust cleaning, electroplates to process and just can simply assemble, half of virgin metal wheelchair weight of being less than in light weight, and cost only is the virgin metal wheelchair half.

Two, break the wheelchair each several part and need the traditional handicraft of assembling respectively, directly assemble pedal, wheel, handrail, seat support, the chair back and just can use on frame assembly, the simple assembling easily of its operation has been shortened the production cycle greatly, improved production efficiency, reduced production costs, cheap.

Three, this wheelchair has used that intensity is good, the alloy plastic of good toughness, so intensity height in light weight, can make by the plastic tube of different colours, bright-colored attractive in appearance light and handy, designs and varieties are many can to compare favourably with the metal wheelchair, plastics can directly reclaim after the long-time service failure of wheelchair, and the low environmental protection and energy saving again of energy consumption do not produce secondary pollution.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Slide block 9 one ends are cylindrical, and the other end is square, and there is the big hemisphere chamber greater than hemisphere square centre.

Cushion block 14 upper ends are the cambered surface that cooperates with the pipe bar, and lower edge has recessed caulking groove.

Left and

right vehicle frame

1,13 is disposable to be injection molded into the hollow pipe framework with alloy plastic, and its cross section is tubulose but does not have pipe joint that also can disposablely be injection molded into the cross section is orthogonal framework.
