Specific implementation mode:When that need not replace bed board 50, bed board sliding block 52 is substantially in the centre of cross outer guide 55
Position, steel wire rope 56 are in relaxed state.
When needing replacing bed board 50, bed board 50 rotates by a certain angle α to coordinate replacement with another cross rail.Bed board
50 by bed board sliding block 52 at a certain angle α direction slide, cross outer guide 55 is by rotating by a certain angle α to adapt to bed board
The sliding of sliding block 52.Just start bed board sliding block 52 to slide into corresponding in guide rail 57 from cross outer guide 55;Subsequent bed board is slided
Block 52 continues to slide along interior guide rail 57.When bed board sliding block 52 slides into the tail end of interior guide rail 57, bed board sliding block 52 withstands pendulum
Plate 59 continues toward front slide, and the beginning of interior guide rail 57 is slided in cross outer guide 55.It is led outside cross then as interior guide rail 57
When continuing to slide into extreme position in rail 55, steel wire rope 56 is straightened substantially, and third spring 62 is stretched;Guide rail 57 exists in then
When continuing sliding in cross outer guide 55, steel wire rope 56 pulls telescopic inner axis 68 to be moved axially to away from the direction of cam 58;That
Flexible housing 66 is in the case where the screw-thread fit of telescopic inner axis 68 drives, and the housing 66 that stretches is rotated around the axis of oneself, cam 58
Also and then flexible housing 66 rotates, and the 4th spring 70, which rotates by a certain angle, stores rotating energy.When flexible housing 66 surrounds oneself
Axis rotate by a certain angle after β, the cam 58 after the β that rotates by a certain angle at this time no longer limits wobble plate 59;So wobble plate 59
Under the promotion of axis bed board sliding block 52, wobble plate 59 puts horizontal position, later bed board sliding block 52 skid off interior guide rail 57 enter it is another
On the cross rail of a bed, so far bed board 50 follows bed board sliding block 52 to be placed on another bed, replaces bed board 50 and finishes.When
After bed board sliding block 52 is detached from wobble plate 59, under the reset response of c-type spring 64, wobble plate 59 is restored to vertical position;In the 5th bullet
Under the reset response of spring 73, flexible housing 66 is restored to home position;In the rotation return of the 4th spring 70 and flexible housing 66
Under, cam 58 is restored to the home position of limit wobble plate 59;Under the reset response of third spring 62, interior guide rail 57 is restored to original
Beginning position.
When the setting first in command 4 and second handle 5 are horizontally situated in the present invention, in Figure 32(a)Shown, first is straight
Angle bent plate 32 and the second angle block of right angle 33 are in horizontal position, and deformation wheel 31 is in flat wheel form.
When deformation wheel 31 needs to be deformed into circle wheel form from flat wheel form, third synchronous belt 17 is not installed at third synchronization
In band gear A 13;In Figure 32(c)Shown, when staff swings the first in command 4, the first in command 4 is through first axle 11, the
One driving gear 15 drives the rotation of the first balladeur train 18;First balladeur train 18 drives the work of the first synchronous belt 21;First is same
It walks band 21 and drives the first synchronizing belt gear B30 rotations;First synchronizing belt gear B30 drives the rotation of the first angle block of right angle 32;Such as figure
In 32(b)Shown, when the rotation of the first angle block of right angle 32 is to the second angle block of right angle 33 at upright position, deformation wheel 31 is deformed into
Circle wheel form;Staff stops swinging the first in command 4 at this time, and it is circle wheel form to maintain deformation wheel 31.
When needing rotation to replace sheet after deformation wheel 31 becomes circle wheel form, staff is by third synchronous belt 17
It is mounted on third synchronizing belt gear A13 in crossing manner;Staff swings second handle 5 or the first in command 4 at this time
The effect of realization is identical, in Figure 33(a)It is shown, by taking the swing of second handle 5 as an example:One side second handle 5 through the second axis 12,
Second driving gear 16 drives the rotation of the second balladeur train 24;Second balladeur train 24 drives the work of the second synchronous belt 22;Second
Synchronous belt 22 drives the second synchronizing belt gear B29 rotations;Second synchronizing belt gear B29 drives the rotation of the second angle block of right angle 33;Separately
One side second handle 5 drives third synchronizing belt gear through the second axis 12, third synchronizing belt gear B14 and third synchronous belt 17
A13 rotates;The direction of rotation of third synchronizing belt gear A13 and third synchronizing belt gear B14 are opposite;In Figure 33(b)It is shown, the
Three synchronizing belt gear A13 drive gear 15 to drive the rotation of the first balladeur train 18 through first axle 11, first;First balladeur train 18
The first synchronous belt 21 is driven to work;First synchronous belt 21 drives the first synchronizing belt gear B30 rotations;First synchronizing belt gear B30
The first angle block of right angle 32 is driven to rotate.Under these two aspects, the rotation of the first synchronizing belt gear B30 and the second synchronizing belt gear B29
It is identical and synchronous to turn direction, thus can still allow deformation wheel 31 to be revolved in the case where it is circle wheel form to keep deformation wheel 31
Turn, and then stir sheet by deformation wheel 31 is sustainable;During sheet is pulled out, deformation wheel 31 and the sheet of half
Pull direction is identical, comparatively the friction between deformation wheel 31 and sheet at this time belongs to rolling friction;The other half deformation wheel
31 and sheet pull direction on the contrary, comparatively the friction between deformation wheel 31 and sheet at this time belongs to sliding friction;Relatively
For sliding friction between traditional change the sheet, the design can reduce resistance caused by the sliding friction of half, more
Be conducive to more quickly replace sheet.
After replacing sheet, staff lays down third synchronous belt 17 from third synchronizing belt gear A13, then
It swings the first in command 4 to rotate the first angle block of right angle 32 to horizontal position, then swings second handle 5 again by the second angle block of right angle
33 rotate to horizontal position;Finally deformation wheel 31 is made to be restored to original flat wheel form.
It is always led with what interior guide rail 57 formed in conclusion bed board 50 of the present invention slides on cross guide rail by bed board sliding block 52
In rail, and bed board sliding block 52 enters on another bed from being skidded off in total guide rail, realizes in the feelings for not moving patient body
Bed board 50 is replaced under condition, and the wound to patient during moving patient is avoided to cause secondary damage;The present invention passes through swing
Deformation wheel 31 is deformed into Round Wheel state by the first in command 4 from flat wheel state, and swinging second handle 5 will drive deformation wheel 31 to rotate,
The deformation wheel 31 of rotation replaces sheet, and sheet can be still replaced in the case where not needing patient and leaving the bed to realize
Purpose;Its is simple in structure, has preferable using effect.
