Convenient bed work process is as follows:

1, manual

Be used to stir preceding lifting wheel (47),, preceding bed board (21) raise, realize seat by front axle (25), front gear (26), preceding tooth bar (24), preceding hinge (23).In the process that pro-bed board (21) raises, preceding pawl (31) pro-thorn wheel (30) is gone up and is slided, and can brake preceding thorn wheel (30) counter-rotating at any time.When current bed board (21) need be transformed into clinostatism by seat, at first preceding brake handle (32) is mentioned, thorn wheel (30) before preceding pawl (31) breaks away from, preceding bed board (21) slowly drops to clinostatism by deadweight.Preceding bed board (21) is when being in clinostatism, and back bed board (8) preferably is in lowering position, and preceding bed board (21) is when being in clinostatism, and back bed board (8) will be horizontal, and the principle that falls with rise of back bed board (8) is identical with preceding bed board (21).When patient needs defecation, at first rotate lifting shaft (37) with the thorn wheel spanner, by manual belt pulley (38), the rotation of leading screw belt pulley (12), leading screw (15) is descended, so side's awl stopper (16) descends, square hole on the middle bed board (33) exposes, rotate carrier wheel axle (19) with the thorn wheel spanner then, by carrier wheel (20), mobile rack (69) makes supporting plate (10) be moved to the edge of a frame (22) by the below of middle bed board (33), patient bores the bedpan side of being placed on the stopper (16) with hands, counter-rotation carrier wheel axle (19) then, the side's of making awl stopper (16) is got back to the below of middle bed board (33), so bedpan is aimed at patient's buttocks, patient-sized just finishes, by above-mentioned method bedpan is moved to the edge of a frame (22), take off bedpan, be put into bed down.

2, electronic

When patient needs seat or clinostatism, at first press the gauge tap (13) of motor (1), make motor (1) work, mention again or press lifting handle (60), so lifting shaft (62) can rise or descend neatly, owing to rise taper key (65), the thrust of drop angle key (59), by rising roller (64), fall roller (58) and promote shifting axle (55) move left and right, under the push-and-pull action of shift fork (53), make mobile clutch (52) and forward clutch belt pulley (51) or reversing clutch belt pulley (54) engagement, by being contained in worm-wheel shaft (57), drive mechanism on the front axle (25), drive front axle (25) forward or reverse, again by front gear (26), preceding tooth bar (24), the transmission of preceding hinge (23) raises preceding bed board (21) or reduction, realizes seat or clinostatism.
