Abstract

The utility model relates to an improved three-fold hospital bed, which comprises a bed rack which is provided with rolling wheels and a bed frame which is supported on the bed rack. A bed plate which is formed by four plates in a hinge connection way is arranged in the bed frame, and the middle plate of the bed plate is fixed on the bed frame. The utility model is characterized in that both ends of the bed rack are provided with two electric jacks which are used for supporting both ends of the bed plate. The electric jacks directly act on the bed plates which need to be folded, and the electric jacks ensure stable starting and uniform speed and do not need the physical strength operation help of other people. Patients can personally press an electric switch to control and adjust the folding degree of the bed plate of the hospital bed or the rising height of the bed plate. The utility model has the advantage of very convenient operation. If remote control electric jacks are used, the use of the hospital bed with the structure can be more convenient.

Description

The modified model three folding bed

The utility model relates to the improvement of sick bed structure, especially a kind of bed board height that can conveniently change is to adapt to the modified model three folding bed that different patient body positions require.

General its bed board of traditional sick bed constitutes in the mode of being hinged by three or four plates, the plate at bed board two all is equipped with movable support frame usually and is provided with the screw mandrel of hand crank, shake hand crank and can regulate the movable support frame of bed board two plate by screw mandrel, thereby realize raising or reduction or perk of a certain plate of bed board, to satisfy the variation requirement of bed patient's position.Used decades though this sick bed prolongs, still can see in the ward at present.But it is found that the sick bed of this structure because movable support frame and screw mandrel fit structure are comparatively complicated, it is too many to pass to the process link that behind the movable support frame bed board is lifted by hand crank and screw mandrel, and it not only operates difficulty very, and effort very.In addition, because the structure of this sick bed is complicated, the as easy as rolling off a log damage of each bracing frame of screw mandrel, and be not easy to repair, thereby cause the sick bed serviceability rate in the existing ward extremely low.

The purpose of this utility model is the deficiency that exists at the said structure sick bed, and a kind of modified model three folding bed of state of each mobile bed plate of energy easy adjustment sick bed is provided.

Modified model three folding bed of the present utility model, comprise: be provided with universal rolling wheel bedstead, be supported on the bedstead the bed frame, be provided with the bed board of forming in the mode of being hinged by four blocks of plates in the bed frame, the intermediate plate of bed board is fixed on the frame, it is characterized in that: the two ends of bedstead are respectively equipped with the electronic jack that acts on bed board two plate.

Another feature of this utility model modified model three folding bed is: the center of bedstead also is provided with a jack that acts on bed board center fixed plate, is provided with the travel(l)ing rest that can cooperate a frame to lift between bed frame and the bedstead.

The described electronic jack of this utility model modified model three folding bed is and shakes the electronic jack of control.

This utility model modified model three folding bed design science, rational in infrastructure, its electronic jack of enabling has substituted complicated screw mandrel movable supporting frame mechanism, has simplified the overall structure of sick bed greatly.The bed board piece that utilizes electronic jack to directly act on to turn up, it starts steady average rate, and need not other people and help the muscle power operation, general patient can press the raising height that sick bed bed board degree of turning up or bed board were handled and regulated to electric switch voluntarily, to satisfy the position comfort requirement of oneself, it is easy to operate; Shake the electronic jack of control if adopt, then can regulate arbitrarily the bed board state of sick bed at a distance, thereby make the use of this structure sick bed convenient.

This utility model modified model three folding bed's concrete structure is provided in detail by the following drawings and embodiment.

Fig. 1 is modified model three folding bed's a structural representation.

Embodiment: can be clear that from Fig. 1, the modified model three folding bed by the bedstead 2 that is provided with universal rolling wheel 1, be erected at the bed frame 4 on the bedstead 2, the bed boards that are arranged in the frame 4 are formed.Described bed board 9 is spliced in the mode of being hinged by the different plate of four block sizes 5,6,7,8, and plate 5 and 8 is two folding backup plate of bed board, and plate 6 be the center fixed plate, and it is installed in the middle part of a frame 4 with fixed form, and plate 7 is the transition flap.The two ends of bedstead 2 are respectively equipped with

electronic jack

3,12, two

electronic jack

3,12 can act on plate 5 and 8 respectively, impels plate 5 to turn up, and impels plate 8 to lift.Bedstead 2 middle parts are provided with an electronic jack 13 that can act on a frame 4 center fixed plates 6, are provided with the travel(l)ing rest 10,11 that cooperates electronic jack 12 to lift a frame 4 and bed board 9 between bed frame 4 and the bedstead 2.Described

electronic jack

3,12 and 13 is and shakes the electronic jack of control.1 of the universal rolling wheel that is arranged on bedstead 2 bottoms can make things convenient for sick bed arbitrarily move.
