Description

Full-plastic wheelchair
Technical field
This utility model relates to a kind of wheelchair, and particularly a kind of confession people with disability and patient can enter accurate diagnostic equipment chamber in hospital, carries out in medical examination and daily life doing the full-plastic wheelchair that the auxiliary moving instrument uses.
Background technology
Existing commercially available wheelchair designs and varieties are various, but most or be made into by metal material, metal tube easily gets rusty, infection its service life, and the metal tube appearance of wheelchair also needs to carry out electroplating processes in addition, can cause the severe contamination of environment, this is all worthless.Because of wheelchair, be also metalwork, 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 be lifted by a plurality of medical personnel, carry on the back in the equipment of delivering to and detected, bring inconvenience to 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 ", though a kind of full-plastic wheelchair easy to use is provided, has solved existing by the existing problem of metal material making wheelchair, its part that also comes with some shortcomings.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of full-plastic wheelchair is provided, except for doing the auxiliary moving instrument in people with disability, patient's daily life, can directly enter precision instrument room in hospital for patient and carry out medical examination, diagnosis, the trouble that greatly alleviates the medical worker is also time saving and energy saving, both met the different demands of different consumers, used more comfortable, safer.
The technical scheme in the invention for solving the above technical problem is: full-plastic wheelchair, by on the vehicle frame formed at two and half vehicle frames, connecting Foldable assembly, brake assemblies, the foot-driven lever assembly, back of the body bar assembly, front-wheel, trailing wheel, handrail, seat board forms, described half vehicle frame is by front bar, rear bar, the integral body that the vehicle frame bar connects into, described Foldable assembly by the cross support bar more than a pair respectively with horizontal seatpost with the gimbal lever, the integral body connected into the joint of base plate, described foot-driven lever assembly is connected on the two halves vehicle frame and is formed by the sliding accessory of the treadle that is hinged with pedal, described back of the body bar assembly carries on the back by connecting backed two the integral body that 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 positioning fastener.
Compared with prior art, the utility model has the advantage of: this Wheelchair structure is improved, numerous parts and pipe joint have been lacked than originally, each assembly is all moulding easily fabrication and installation, and just can operate installation without instrument, and there is no exposed securing member, appearance is clean and tidy, attractive in appearance also has elasticity, use more comfortablely, the large 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.Each movable members has all been installed positioning fastener 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.Form former employing securing member between the part of each large assembly and connect, now adopt injection moulding to be fixedly connected with, intensity is better, it is more firm to connect, it is safer to use, and suitable especially overweight consumer is used.The foot-driven lever assembly is separate piece, and sliding inserting is connected on the front bar of half vehicle frame, can, according to the height of consumer and the high and low position of long and short adjusting treadle on half vehicle frame of foot, meet the different demands of consumer.Increase push rod between two back of the body bars, the intensity that increases back also makes backrest not yielding, and not only consumer's use is comfortable, also makes to promote wheelchair operation more convenient, laborsaving.
