Technical field

This utility model relates to medical hospital bed technical field, particularly a kind of scissors type elevating sick bed.

Background technology

When medical personnel check patient or treat or shift, need to be according to medical personnel's actual medical or the in good time adjustment bed surface height of nursery work situation.Scissors type elevating sick bed is a kind of lifting invalid bed conventional in Hospitals at Present, known scissors type elevating sick bed comprises base, crane and bedstead, crane comprises 4 elevating levers, push rod and be located at base and bedstead on runner frame, homonymy first, the second elevating lever is hinged, the 3rd of homonymy, the 4th elevating lever is hinged, elevating lever after hinged connects by 1～2 synchronizing bar, first, the 3rd elevating lever one end is hinged on respectively the both sides of bedstead, the other end is hinged on the runner frame of base, second, the 4th elevating lever one end is hinged on respectively the both sides of base, the other end is hinged on the runner frame of bedstead, push rod two ends are hinged on respectively on base and synchronizing bar or are hinged on two synchronizing bars, piston by push rod stretches out or shrinks, make piston rod drive elevating lever to slide accordingly on runner frame by synchronizing bar, thereby realize the rising of bedstead or the action of decline.Yet the articulated manner of existing push rod has the following disadvantages: (1), if push rod is hinged on base and synchronizing bar, base is lightweight, and bottom is with roller, may cause a body shakiness when bedstead heave amplitude is slightly large, even occurs the situation of bed body displacement; (2) if push rod is articulated with on two synchronizing bars, the elevating lever stretching degree of scissors crossing is limited, causes crane lifting degree limited, causes sick bed to be difficult for folding, and volume is larger, and carrying is inconvenient; (3) push rod or adopt electric pushrod or manually control push rod, elevating control function singleness.

Utility model content

The purpose of this utility model is to provide a kind of scissors type elevating sick bed, overcome that the sick bed lifting bed body that the articulated manner of existing scissors type elevating sick bed push rod causes is unstable, the defect of the large carrying inconvenience of volume and elevating control function singleness, provide heave amplitude large, be easy to folding, lifting process bed body is stable and manual and electric dual-purpose is controlled scissors type elevating sick bed.

In order to reach above-mentioned object, this utility model adopts following concrete technical scheme: a kind of scissors type elevating sick bed, comprise base, crane, bedstead and bed board, described crane comprises 4 elevating levers, push rod and be located at base and bedstead on runner frame, first of homonymy, the second elevating lever is hinged, the 3rd of homonymy, the 4th elevating lever is hinged, first, the 3rd elevating lever one end is hinged on respectively the both sides of bedstead, the other end is slidably connected by the runner frame formation of sliding axle and base, second, the 4th elevating lever one end is hinged on respectively the both sides of base, the other end is slidably connected by the runner frame formation of sliding axle and bedstead, elevating lever after hinged is connecting by two synchronizing bars near base one side, near the synchronizing bar of runner frame one side and the cylinder ends of push rod, be rotationally connected, the other end of push rod is rotationally connected with bedstead, synchronizing bar away from runner frame one side is installed with controller, described push rod is the electric pushrod with manual setter, and described controller connects power supply access port, electric pushrod and operator.

Described bed board is divided into backboard, seat and sole, and the second electric pushrod is installed between described backboard and bedstead, and the 3rd electric pushrod is installed between described sole and bedstead, and described the second electric pushrod, the 3rd electric pushrod are connected with controller.

Compared with prior art, the utlity model has following advantage: push rod and bedstead in (1) crane are hinged, bedstead heavier can push rod stretch out with contraction process in firm lathe bed, make the elevating lever of scissors crossing be flared to suitable angle, adjusting sick bed that can be stable is to optimum height; (2) push rod in crane and bedstead carry out hingedly, can make the elevating lever of scissors crossing open completely, can facilitate easily the altitude mixture control of sick bed to minimum, and easily folding, reduces sick bed volume; (3) adopt the electric pushrod with manual setter, in conjunction with controller and operator, can realize the electric-hand driven two-purpose of push rod and control.
