Description

Technical Field

[0001] The present invention relates to a nursing bed, and more particularly to a modular quick-install multifunctional nursing bed. Background Art

[0002] With the acceleration of the aging process of the population, more and more patients need long-term bed rest treatment and rehabilitation, so the demand for nursing beds is also increasing. In order to meet the various nursing needs of patients, the functions of existing nursing beds are becoming more and more comprehensive, such as bed lifting, patient back lifting, leg bending and turning over, etc., which also makes the structure of nursing beds more and more complicated and bloated.

[0003] Existing nursing beds are usually integral structures after leaving the factory, with only the bed board, guardrails, bed end baffles and other parts being detachable structures. After the entire bed is folded and packaged, the length is more than 2 meters, the width is more than 1 meter, and the height is approximately 0.5 meters. This results in the nursing bed being large in size during transportation, inconvenient to transport and unload, and high in transportation costs.

[0004] Moreover, the nursing bed is manufactured in a factory, which requires high matching accuracy between the functional modules, and is relatively difficult to manufacture and assemble, which is not conducive to improving production efficiency and reducing production costs. Although there are foldable and assembled nursing beds in the prior art, they are usually simple beds that cannot meet the multifunctional nursing needs of patients. Summary of the invention

[0005] 1. Technical problem to be solved by the invention

[0006] The purpose of the present invention is to overcome the above-mentioned shortcomings of the existing nursing beds and to provide a modular quick-install multifunctional nursing bed. The technical solution of the present invention is adopted to divide the nursing bed into a lower frame module, a lifting drive module, an upper bed frame module, a turning drive module, a turning bed frame module and a back lifting and leg flexing module. The various parts are assembled using a modular quick-install structure, which can reduce the packaging size of the nursing bed and effectively reduce the transportation cost of the nursing bed. Moreover, each combined part is independently manufactured with high manufacturing precision and more convenient assembly, which can improve the production efficiency of the nursing bed and reduce the production cost.
