Abstract

The invention discloses a full-plastic wheelchair. The structure of the full-plastic wheelchair is improved. Compared with the number of parts and pipe joints of an original wheelchair, the number of parts and pipe joints of the full-plastic wheelchair is reduced, and the full-plastic wheelchair can be installed without the need of a tool. Each half vehicle frame is composed of a front rod, a rear rod and a vehicle frame rod in a connected mode. A folding assembly is composed of more than one pair of cross supporting rods, transverse seat poles and connectors in a connected mode, wherein each transverse seat pole is provided with a balancing pole, and each connector is provided with a bottom plate. Each foot rest lever assembly is connected to one half vehicle frame through a foot rest level in a sliding and matched mode, wherein a pedal is hinged to each foot rest level. A back lever assembly is connected with a push rod through two back levers by means of locking hoops, wherein the two back levers are connected with a backrest. Locating lock buckles are installed at the connection positions between an armrest assembly and each half vehicle frame, between the back lever assembly and each half vehicle frame and between each foot rest lever assembly and each half vehicle frame. According to an existing full-plastic wheelchair, parts of each big assembly are connected through fasteners. Parts of each assembly of the existing full-plastic wheelchair are fixedly connected in an injection molding mode, so that the strength is better, connecting is firmer, using is safer, and the full-plastic wheelchair is particularly suitable for overweight consumers. The position of each foot rest lever on one half vehicle frame of each foot rest lever assembly can be adjusted according to the height of a consumer and the length of the foot, and therefore different needs of consumers can be met. Due to the fact that the push rod is added between the back rods, the strength of the back portion is improved, the backrest is not prone to deforming, the consumers feel comfortable when using the full-plastic wheelchair, and push of the full-plastic wheelchair saves effort and is more convenient.

Description

Full-plastic wheelchair

Technical field

The present invention relates to a kind of wheelchair, particularly a kind of confession people with disability and patient can enter accurate diagnostic equipment chamber in hospital, carry out doing in medical examination and the daily life full-plastic wheelchair that the auxiliary moving instrument uses.

Background technology

Existing commercially available wheelchair designs and varieties are various, but most still be made into by metal material, metal tube easily gets rusty, infection its service life, and the metal tube appearance of wheelchair also need be carried out electroplating processes in addition, can cause the severe contamination of environment, this all is worthless.Be metalwork because of wheelchair also, when hospital carries out physical therapy treatment, diagnosis and treatment inspection to patient, especially as x ray room, CT Room, Magnetic Resonance (MR) Room/ MRI Room, the patient that can not walk about can not be with in the wheelchair promotion room, have to lift, carry on the back in the equipment of delivering to and detect by a plurality of medical personnel, bring inconvenience for medical personnel's work, both increased labor intensity and time, bring embarrassment and misery to patient again.

China Patent No. 201010154305.X " full-plastic wheelchair " has solved existing by the existing problem of metal material making wheelchair, its part that also comes with some shortcomings though a kind of full-plastic wheelchair easy to use is provided.

Summary of the invention

Technical problem to be solved by this invention is: a kind of full-plastic wheelchair is provided, except for doing in people with disability, the patient's daily life the auxiliary moving instrument uses, the precision instrument room carries out medical examination, diagnosis is used but patients directly enters in hospital, the trouble that alleviates the medical worker greatly is also time saving and energy saving, both satisfied the different demands of different consumers, used more comfortable, safer.

The present invention addresses the above problem the technical scheme that adopts: full-plastic wheelchair, connect Foldable assembly by the vehicle frame that constitutes at two and half vehicle frames, brake assemblies, the foot-driven lever assembly, back of the body bar assembly, front-wheel, trailing wheel, handrail, seat board is formed, described half vehicle frame is by preceding bar, back bar, the integral body that the vehicle frame bar connects into, described Foldable assembly by the intersection support bar more than a pair respectively with the band gimbal lever the horizontal bar of sitting, have the integral body that the joint of base plate connects into, described foot-driven lever assembly is joined to be connected on the two halves vehicle frame by the treadle cunning that is hinged with pedal and is constituted, described back of the body bar assembly is by connecting the integral body that backed two back of the body bars connect into by lock ring and push rod, described handrail, back of the body bar assembly, foot-driven lever assembly and two halves vehicle frame junction also are equipped with the location snap close.

Compared with prior art, the invention has the advantages that: this Wheelchair structure improves, numerous parts and pipe joint have been lacked than originally, each assembly all is moulding and easily fabrication and installation, and just can operate installation without instrument, and there is not exposed securing member, appearance is clean and tidy, attractive in appearance also to have elasticity, use more comfortablely, the big establishment of component of each of wheelchair is convenient to separately streamline production and processing and is assembled.Therefore be convenient to the production management of factory, reduce labor intensity, increase work efficiency.The location snap close has all been installed at each movable members such as handrail, back of the body bar, foot-driven lever place, and the time, wheelchair can not become flexible yet, more reasonable structure with after long.Constitute that former employing securing member connects between the part of each big assembly, now adopt injection moulding fixedly connected, intensity is better, it is more firm to connect, it is safer to use, and suitable overweight especially consumer uses.The foot-driven lever assembly is separate piece, and sliding inserting is connected on the preceding bar of half vehicle frame, can satisfy the different demands of consumer according to the height of consumer and the high and low position of long and short adjusting treadle on half vehicle frame of foot.Increase push rod between two back of the body bars, the intensity that increases the back also makes backrest not yielding, and not only consumer's use is comfortable, also makes the promotion wheelchair operation more convenient, laborsaving.
