Backrest rotatable mechanism for stretcher

Abstract

The invention relates to the field of medical equipment, in particular to a backrest rotatable mechanism for a stretcher. The backrest rotatable mechanism comprises a bedstead, a backrest frame and a connecting device, and the connecting device comprises first components, pin shafts, a seat board frame, second components, first dowels, idler wheels, second dowels and third components; the first components, the second components and the third components are symmetrically arranged at the inner side of the bedstead, and a first boss and a second boss are arranged on each first component; a backrest plate is arranged on the backrest frame, and structures which can conduct translation and slant turn-over relatively are formed between the backrest frame and the bedstead; a seat board is arranged on the seat board frame to form a supporting structure for the hip and above when the human body sits, and a connecting structure with the angle capable of being adjusted is formed between the seat board and the bedstead, so that a first panel is assisted in aslant moving relative to the bedstead; the backrest frame and the first components are connected through the pin shafts, and the pin shafts are provided with the idler wheels. The backrest rotatable mechanism for the stretcher is simple in structure, the movement of the seat board and the backrest plate is good in coordination, and the backrest rotatable mechanism has high practical value.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a backrest rotatable mechanism for a stretcher trolley. Background technique [0002] At present, there are many medical chairs, medical beds, and stretchers in the field of medical equipment, which play a great role in auxiliary treatment in the medical field. However, although the seat of a traditional medical seat or stretcher can be adjusted by an adjustable mechanism to adjust the patient's sitting posture, its comfort is relatively poor, and the patient is likely to cause discomfort after sitting for a long time. At the same time, the coordination of the position adjustment of existing medical seats or stretchers is relatively poor, the adjustment is not convenient enough, and sometimes it is difficult for patients to adjust to a comfortable position. [0003] Therefore, based on the above, the present invention provides a backrest rotatable mechanism for a stretcher, in o...
