Abstract
The present invention discloses a back lifting mechanism of a bed, which comprises a drive motor arranged on a bed frame connected with a rotating shaft and a drive shaft. A supporting rod is respectively fixed to both ends of the rotating shaft. A crank connected with a telescoping rod of the drive motor is also fixed to the rotating shaft. A crank connected with a slide rod through a connecting rod is respectively fixed to both ends of the drive shaft. One end of the slide rod is fixed to a bed plate, and the other end of the slide rod is connected to the bed frame. The surface of a mattress of the present invention can be basically dovetailed with the moving track of the surface of the back of a human body in the process of lifting the back. Friction is prevented, and human body movement is reduced in the process of movement in the maximum limit.
Description
Technical field:
The present invention relates to a kind of mechanism for lifting back.
Background technology:
Human body is transformed into from lying on the back the process of sitting posture, generally is to be that rotating shaft rotates with the hip joint, and elongate on the back of the body, buttocks surface, and belly shrinks.At present, in Bed with special provision for nursing with back of the body function, it plays back of the body action is to shrink along its length with mattress surface, if human body is lain on the back and finished back of the body action on such bed, contract because above-described one stretches one, human body back and mattress surface generation relative motion cause friction, and the people knows from experience the distance of being passed a big section by bed to the direction of pin.
The objective of the invention is to: the mechanism for lifting back that a kind of Bed with special provision for nursing is provided; make the mattress surface can be identical substantially in playing unlucky moving process with the movement locus on human body back surface; avoid friction; and reduce moving of human body in the motion process to greatest extent, to solve the problem that prior art exists.
The present invention constitutes like this: it comprises the drive motors (4) that is contained on the bedstead (2), on bedstead (2), be connected with rotating shaft (6) and power transmission shaft (9), be fixed with support bar (13) at the two ends of rotating shaft (6), the other end of support bar (13) is connected on the bed board (1); Also be fixed with first crank (5) and second crank (24) in rotating shaft (6), first crank (5) links to each other with the expansion link of drive motors (4), and second crank (24) links to each other with the 3rd crank (23) on being fixed on power transmission shaft (9) by connecting rod (10); Two ends at power transmission shaft (9) are fixed with four-throw (8), and four-throw (8) links to each other with slide bar (20) by connecting rod (7), and an end of slide bar (20) is fixed on the bed board (1), and the other end is connected again on the bedstead (2).
Be connected with roller (15) on the other end that is fixed in the support bar (13) in the rotating shaft (6), roller (15) is enclosed in the chute (3) that is fixed on the bed board (1).
Slide bar (20) is connected with pulley (22) again at the opposite side of an end that is connected with connecting rod (7), and pulley (22) is enclosed in the arc groove (21) that is fixed on the bedstead (2).
Roller (15) and pulley (22) also can be rotating slide block.
Drive motors (4) also can be manual telescoping mechanism.
Compared with prior art; of the present invention simple in structure, its mattress surface can be identical substantially with the movement locus on human body back surface in playing unlucky moving process, avoided friction; and reduced moving of human body in the motion process to greatest extent, reached purpose of the present invention.
