Description
Technical field
The present invention relates to a kind of main also vitals light full-plastic wheel carrier forming full-plastic wheelchair, make Move tool by itself and the supporting light full-plastic wheelchair be made into of other accessory for people with disability, patient.
Background technology
The each parts now forming wheelchair mostly are metalwork, polishing plating need be carried out through surface treatment, therefore severe contamination and the destruction of environment is caused, because metalwork directly can not enter the indoor use of high-end precision equipment, add the work efficiency that inconvenience also affects doctor simultaneously to medical worker and patient.
China Patent No. 201010154305.X " full-plastic wheelchair " is though also provide a kind of easy to use, full-plastic wheelchair that directly can enter the indoor use of hospital high end equipment, the part but it also comes with some shortcomings, as structure is more complicated, many, the difficult processing of part, assembling, go back heavy weight.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of light full-plastic wheel carrier, its structure is simple, part is few, easy making, installation, matching component as full-plastic wheelchair uses, light especially by its supporting full-plastic wheelchair weight made, use more convenient, directly can enter in the high-grade precision equipment of hospital and use, meet the different demands of consumer.
The present invention's adopted technical scheme that solves the problem is: light full-plastic wheel carrier, comprise the vehicle frame be made up of two halves vehicle frame, with the Foldable assembly be connected on vehicle frame, described half vehicle frame is by upper, sheer pole, before, in, the overall structure that rear straight-bar is injection molded into, described Foldable assembly is by the two ends of the cross support bar of more than a pair, be fixedly connected on half vehicle frame respectively and with in the horizontal seatpost of the gimbal lever, described two horizontal seatposts are arranged on the cross tube of two halves vehicle frame, and Foldable assembly to be fixedly connected in two halves vehicle frame on straight-bar and sheer pole with the described gimbal lever and base plate.
Compared with prior art, the invention has the advantages that: this wheel carrier structure is improved, its structure is simpler, part is few, and can direct disposable injection molding integrally, eliminate and much assemble processor, not only save time, the laborsaving but also production of more convenient factory, management, also reduce labor intensity.Because each parts can directly be injection molded into, instrument is not needed more easily to install, and each major part forming wheel carrier is all made up of the entirety of cross section in the H type of band reinforcement, therefore its intensity is good, firm, material-saving, also weight are light especially, light by the supporting full-plastic wheelchair deal made of this wheel carrier, wheelchair easily promotes, it is more convenient to use, dexterousr.
