Also, the second motor 104 is arranged on L-type fixing piece 101, for combining driving L-type activity by sprocket wheel chain
Part 102 is rotated around torsion shaft 110.In embodiment, the first and second motors are stepper motor, however, the present invention is not limited thereto.
In embodiment, circular hole is provided on the horizontal arm of L-type movable part 102, first motor 103 is by being installed on circular hole
On ball-screw 119 connect with the horizontal arm of the L-type movable part 102.
In embodiment, the upright arm of L-type fixing piece 101 is provided with worm type of reduction gearing 111, and wherein worm and gear subtracts
The output shaft 112 of fast device 111 is equipped with the first sprocket wheel 113 and torsion shaft 110 is equipped with the second sprocket wheel 114, the first sprocket wheel 113
Be connected with chain 115 on the second sprocket wheel 114, to form sprocket wheel chain combination so that with worm type of reduction gearing 111
L-type movable part 102 is rotated around torsion shaft 110 under the driving of second motor 104 of connection.
As shown in Figure 1, the horizontal arm of L-type fixing piece 101 is equipped with fixed shovel board 116, and the water of L-type movable part 102
Flat arm is equipped with connecting plate 117, is used for installation activity shovel board 118.
In embodiment, it is additionally provided with limited block on the horizontal arm of L-type fixing piece, for limiting the stroke of guide rail 108.
Fig. 2 shows the embodiments for the stretcher transfer device for using turnover device according to an embodiment of the present invention.Such as Fig. 2 institute
Show, stretcher transfer device includes translation mechanism 201, is fixed on baffle 202;And turnover device 203 according to the present invention, with
Just stretcher shovel board is transferred among hospital bed, safely scoops up patient.Turnover device 203 of the invention mainly includes L-type activity
Part 204 and L-type fixing piece 205 are respectively arranged with activity shovel board 206, fixed shovel board 207 thereon.In the transport process of patient,
Structure design is full decoupled by the rotation of stretcher and translation, increases the safety that transshipment acitivity shovel takes patient to act.
Fig. 3 shows the schematic diagram after the stretcher transfer device translation using turnover device according to an embodiment of the present invention.Fig. 4
Schematic diagram after showing the translation of stretcher transfer device and overturning using turnover device according to an embodiment of the present invention.Fig. 5 is shown
Use schematic diagram of the stretcher transfer device of turnover device according to an embodiment of the present invention after integral translation.Such as the institute of Fig. 3,4 and 5
Show, when stretcher transfer device is in original state, first motor 301 and the second motor 302 do not work, and guide rail reaches L-type and fixes
In the groove of part 303, so that L-type movable part 304 is in contact with L-type fixing piece 303.Stretcher transfer device, which starts to work to shovel, takes disease
When patient on bed, first motor 301 is first powered on rotate driving guide rail and slides along the groove in L-type fixing piece 303, guide rail
It is detached from the groove of L-type fixing piece, is the overturning of L-type movable part 304 so that L-type movable part 304 be made to separate with L-type fixing piece 303
Gap is retained, as shown in Figure 3.Second motor 302 is powered therewith exports turning moment by worm type of reduction gearing 305, drives
First sprocket wheel rotates, and then the rotation of the second sprocket wheel is affected through chain, and the second sprocket wheel rotation driving L-type movable part 304 is around overturning
Axis overturning, and then the overturning of realization activity shovel board 306, as shown in Figure 4.The translation mechanism 307 of stretcher transfer device works, and will consolidate
Determine shovel board 308 be moved to patient body contacts-side-down, as shown in Figure 5.Hereafter, the second motor 302 reversely rotates, and passes through first
The reverse flip of sprocket wheel and chain pair realization activity shovel board 306, when activity shovel board 306 is back to horizontal position, first motor
301 reversely rotate, so that fixed shovel board 308 and patient's left contact, while guaranteeing two stretcher shovel boards and relative position
It is constant, it completes to take patient's shovel to the movement on stretcher shovel board.
As described above, simulating medical staff the present invention provides a kind of turnover device using manual shovel board and scooping up patient
Process and be translated into driving shovel board linear motion and flip-flop movement, the former can guarantee patient will not in transport process
Occur sliding phenomenon, the latter is responsible for patient from hospital bed " shovel " to transfer car(buggy).The turnover device only needs people's remote control operation i.e.
Can patient transhipment, reduce the working strength of medical staff, reduce in handling process to external dependence and to patient
Caused by injure.
Obviously, the above embodiment is merely an example for clearly illustrating the present invention, and is not to of the invention
The restriction of embodiment.For those of ordinary skill in the art, it can also be made on the basis of the above description
Its various forms of variation or variation.There is no necessity and possibility to exhaust all the enbodiments.And these belong to this hair
