Light full-plastic wheel carrier

Abstract

A light full-plastic wheel carrier comprises a vehicle frame which is composed of two half vehicle frames and a folding assembly. The folding assembly is connected to the vehicle frame. Each half vehicle frame is of an integrated structure and is formed through an upper cross rod, a lower cross rod, a front straight rod, a middle straight rod and a rear straight rod in an injection molding mode. According to the folding assembly, more than one pair of cross supporting rods is arranged, the two ends of each supporting rod are fixedly connected to one half vehicle frame and a transverse seat post provided with a balancing pole respectively, the two transverse seat posts are installed on the cross rods of the two half vehicle frames, and the folding assembly is fixedly connected to the middle straight rod and the lower cross rod of each half vehicle frame. The light full-plastic wheel carrier is simple in structure, the number of parts of the light full-plastic wheel carrier is relatively smaller than that of an original wheel carrier, the whole light full-plastic wheel carrier can be directly processed in a once-forming and injection molding mode, a lot of assembly processing procedures are eliminated, and the light full-plastic wheel carrier saves time and effort, and is convenient for a factory to produce and manage, and capable of relieving labor intensity. Due to the fact that each part is formed in a direct injection molding mode, installation of each part does not need a tool, the parts are easier to install, each main part which constitutes the wheel carrier is composed of a whole, the section of the whole is H-shaped and provided with a reinforcing rib, and therefore the light full-plastic wheel carrier is good in strength, firm, capable of saving materials, and light in weight. A full-plastic wheelchair manufactured through the light full-plastic wheel carrier is light in weight, convenient to push and use, lighter and handier.

Description

technical field [0001] The invention relates to a light-duty all-plastic wheel frame which is the main and important part of an all-plastic wheelchair. The light all-plastic wheel frame is made by matching it with other accessories, and is used as a moving tool for disabled people and patients. Background technique [0002] Most of the components that make up the wheelchair are metal parts, which need to be polished and electroplated after surface treatment, thus causing serious pollution and damage to the environment, because the metal parts cannot be directly used in the high-end precision equipment room, which adds a lot of inconvenience to medical staff and patients. Also affect the doctor's work efficiency. [0003] Although Chinese Patent No. 201010154305.X "all-plastic wheelchair" also provides a kind of all-plastic wheelchair that is easy to use and can directly enter the high-end equipment room of the hospital, it still has some shortcomings, such as complicated str...

Problems solved by technology

[0002] Most of the components that make up the wheelchair are now metal parts, which need to be polished and electroplated after surface treatment, thus causing serious pollution and damage to the environment, because the metal parts cannot be directly used in the high-end precision equipment room, which adds a lot of inconvenience to medical staff and patients. It also affects the doctor's work efficiency

[0003] Although Chinese Patent No. 201010154305.X "all-plastic wheelchair" also provides a kind of easy-to-use all-plastic wheelchair that can directly enter the high-end equipment room of the hospital, it still has some shortcomings, such as complicated structure, many parts, Difficult to process, assemble, and heavy
