Problems solved by technology

Therefore, it often brings difficulties to the structure and transmission settings of the entire medical chair in terms of the power adjustment and manual adjustment of the power system being compatible and independent of each other.
However, setting multiple independent systems too complicated is easy to increase manufacturing costs and increase the difficulty of subsequent maintenance

Abstract

A backrest-angle-adjustable and safe medical chair comprises a backrest assembly (3) and a base assembly (4). The backrest assembly (3) comprises a backrest bottom plate (31) and a backrest face plate (421) connected with the backrest bottom plate (31) through backrest springs (43). The backrest bottom plate (31) and the backrest face plate (421) are supported by a fixed shaft (41) on a base support (40) in a rotatable mode through a bottom plate drive gear (311) and a face plate drive gear (42) respectively. The bottom plate drive gear (311) is meshed with a power adjustment gear (37) coaxially connected with a worm wheel (371) and is driven by power. The worm wheel (371) is meshed with a worm (372) connected with a motor through power and is driven by power.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a safe medical chair with an adjustable backrest angle. Background technique [0002] In the medical field, it is often necessary to use some treatment chairs, such as some dental or ophthalmological surgical chairs. The backrest angles of these medical chairs often need to be flexibly adjustable, so as to adapt to the angle and position adjustment needs during the treatment process. [0003] In some current medical chairs, the adjustment of the backrest angle is usually driven by power, such as a motor. However, in the process of use, it is often necessary to manually adjust and slowly adjust the patient's treatment site, so as to meet the doctor's surgical operation or observation needs during the treatment process. This requires a manual adjustment function while power adjustment is provided. Therefore, the power adjustment and manual adjustment power system are compatible ...
