Specific implementation method: stand up four jiaos an of underframe 7 and horn ring is housed carries out, be hinged and connected by elevating mechanism and bedstead 6 simultaneously, make the bed surface can integral elevating and inclination.The top two cover mechanisms that AB section bed board and DE section bed board are turned up of also being equipped with of bedstead 6.Stand up a bed surface and laterally be divided into five sections, A section bed board 1, D section bed board 4 and E section bed board 5 are common bed boards, and the mattress of bed also is a conventional mattress relatively.A section bed board 1 is that the head of human body is shorter, and D section bed board 4 and E section bed board 5 are shanks of the person, stands up all functions that bed has ordinary hospital bed on the present market.By in present hospital and the family to the nursing paralytic long-term observation.Standing up to patient in the nursing process is the work that must will do, and the number of times of every day is many more beneficial to patient more.When standing up, two actions be arranged in conjunction with patient's bodyside being twisted over to the paralytic.First will move the position to patient earlier, moves the certain distance This move from the centre of sick bed to the limit and requires great effort most.Second is only the health that lifts patient makes it rollover.According to the This move principle, with the B section bed board 2 and the C section bed board 3 that stand up bed just the trunk partial design that lies on a bed from shoulder to buttocks of people become chain-belt type to roll.Chain belt is to be connected to form by chain sheet 28 by carrier bar 8 polyliths, can rotate continuously as conveyer belt.Carrier bar 8 is equivalent to a chain link of chain, is embedded in the thin-walled square shaped pipe 26 two ends endoporus that are cut into certain-length mutually by two chain wrench 27.Chain wrench 27 is foundry goods, is cast with two cylinders chain rivet just at the cuboid end face.Two cylindrical centre-to-centre spacing equal the pitch of supporting wheel 23.Corresponding to the mattress of B section bed board 2 and C section bed board 3, be drum shape around two bed boards, under the effect of gravity and friction, can rotate synchronously with chain belt.B section bed board 2 and C section bed board 3 vertically be divided into three, intermediary one the time is in horizontal level standing up action.Two of the right and left can be divided into and turning up.Chain belt also is divided into three sections, and every section chain belt is by the 19 supporting transmissions of two row's backing rolls.It is drive rolls that six rows have four rows in the backing rolls 19, about a row respectively to be arranged in the chain belt backing roll of two bed boards be driven roll.The design of backing roll 19 and carrier bar 8 are similar, are embedded in the thin-walled square tube 25 two ends endoporus that are cut into certain-length mutually by two supporting wheels 23 and form.The spindle nose end face axial of bogie wheel 23 is processed with 2 apertures and supporting wheel 23 axial centre line parallels, symmetry.Also have the vertical arc shaped groove in one and two holes.It must be universal joint that B section bed board 2 is connected transmission with the backing roll 19 of C section bed board 3.Because of bed board 2 also has the action of turning up when patient sits up.But existing universal joint volume is excessive, so adopt two U shaped steel cards 24 to interlock, pitches respectively in the axial end aperture of the supporting wheel 23 of two sections bed boards.Can in aperture, be free to slide and form universal connection transmission.In the circular hole on the same steel plate of the elephant ear that stretched out on support plate 10 and back support plate 9 and preceding frame support plate 30 both sides before chain belt two row's backing rolls 19 of one were installed in the middle of the B, C section bed board, support by sliding shaft sleeve.Four of two chain belts row's backing rolls 19 are mounted in above 8 blocks of lateral bending plates 11 about both sides.Because B section bed board 2 is tubbiness with C section bed board 3 corresponding mattresses,, rotate around bed board so it will pass below the bed board when motion.Gap between while two sections mattresses can not be excessive, and crossing conference influences the comfort level that patient lies on a bed.Support plate 10 rear carrier plates 9 must be made with sheet metal with preceding frame support plate 30 and lateral bending plate 11 before the institute.Under the situation of proof strength, the thickness of steel plate is the smaller the better.The top of these several support plates is screwed the holder chain side bar 20 that is processed into nylon strip is installed at all.It is the track of chain belt, and the chain wrench 27 that is used for supporting carrier bar 8 two ends slides in the above and guarantees the smooth of bed surface.Two sections bed board both sides of BC side plate is installed on front supporting plate 10 turns up mechanism.Be welded with a stationary steel bushing in the bottom of front supporting plate, two rolling bearings are arranged in the steel bushing, the axle of turning up sprocket wheel 14 is installed in the rolling bearing endoporus.Coaxially with square key centering block 16 is housed fixedly, the two sides of centering block 16 respectively is screwed installs one and recovers control plate 17 and turn up and promote bearing 22.The lower end of fork 15 and is being welded on two circular shafts of front supporting plate 10 hingedly, and the upper end links to each other with connecting rod 18, middlely installs one with screw and returns control bearing 21.Slip cap above the connecting rod 18 is hinged on being fastenedly connected on the axle of lateral bending plate 11.Do not standing up when action, centering block 16 is in twice controls in intermediate vertical position plate 17, and is installed in 15 intermediary times control bearings of fork and throws off control simultaneously, at this moment manually also can turn up the both sides side plate.Turning up under the drive of sprocket wheel 14 and can respectively rotate 0-90 ° to both sides respectively standing up when action centering block 16.During centering block 16 motions, turn up the promotion bearing 22 synchronous forks 15 that promote and outwards swing, at this moment be contained in 15 intermediary times control bearings 21 of fork and be cut into back in the bent angle of control plate 17.At centering block 16 during, return control plate 17 and just catch on back control bearing 21 fork 15 is moved to backswing to back rotation.Because connecting rod 18 is hinged with fork 15, vertical both sides discriminable turning up of bed board of B section bed board 2 and C section bed board 3 put down so connecting rod 18 just can drive 11 actions of lateral bending plate.The dynamical system of chain belt transmission be installed in rear carrier plate 9 above, drive two two supporting live-roller sprocket wheels 13 on the spindle nose that is installed in intermediary two row's backing rolls 19 by main chain bar 12 and drive intermediary two row's backing rolls 19 and rotate.Again by chain pass to bedside two row backing rolls 19 whole carrier bars 8 are moved simultaneously.9 supportings of C section bed board 3 forward support plates 10 and rear carrier plate, two support plates be fixedly mounted on bedstead 6 above, the centre has pull bar to link to each other to play location and fixation.A section bed board 1 welds together with external crucible board mount 29, and simultaneously preceding frame support plate 30 is also integrally welded with external crucible board mount 29.B section bed board 2 is installed in the top formation one of external crucible plate framework 29, and is hinged with hinge and C section bed board 3.The centre of D section bed board 4 and E section bed board 5 also is to be connected together with hinge to bend the district.The reuse hinge is connected with bedstead 6.Following reuse hinge method is turned up mechanism with foot and is linked to each other, and A section bed board 1 will be in horizontal level with D section bed board 4E bed board 5 when standing up action.If manually to be that power will drive the foldings pendulum sprocket wheel 14 that is installed in above the preceding bed board 10 with chain earlier, centering block 16 is turned up bearing 22 promotion forks 15 to the one side swing, and vertical side plate one side of B section bed board 2 and C section bed board 3 is turned up.Turn up action with connecting rod 18 in line the time at fork 15 and be in the dead point, centering block 16 can not be swung above also being stuck in of two jack-posts being welded on front supporting plate 10 again.Another group chain of reuse drives the main chain bar 12 drive backing roll drive sprockets 13 that are installed in above the rear carrier plate 9 rolls the chain belt generation, and patient just can stand up action at any angle under the effect of friction.If be power with the motor, two actions will be carried out simultaneously, and when bedside was turned up, chain belt just began to rotate, and by control circuit, the control human body stands up angle, also can not have timing automatic standing up under nursing staff's situation on the scene at night simultaneously.
