On the transverse slat 11 of movable plate 2.Oil cylinder 8 can drive first movement plate 2 to be slided along guide rail and rotate band by 6 drive sprocket 4 of chain
Dynamic second movable plate 1 slides.Such as：When oil cylinder 8 works, oil cylinder 8 pushes cylinder rod 8 ' to be moved to the left, in pushing away for cylinder rod 8 '
Under dynamic, first movement plate 2 is moved to the left, and since 6 lower end of chain and bottom plate 3 are fixed, chain 6 can not be translatable, but sprocket wheel 4
Movement has occurred, since chain 6 is engaged with sprocket wheel 4, the master positioned at left side close to transverse slat 11 can be caused under the action of chain
Movable sprocket rotates counterclockwise, drive sprocket driven under the action of chain on the right side of driven sprocket also occur counterclockwise turn
It is dynamic, since 6 upper end of chain is fixedly connected with the second movable plate 1, to be rotated counterclockwise with sprocket wheel, just drive second to move
Movable plate 1 is moved to the left.To make first movement plate 2 that the second movable plate 1 be driven to link under the driving of oil cylinder.
Since 6 lower end of chain of the present invention is fixedly connected with bottom plate 3, first movement plate 2 is sent out under the action of oil cylinder 8
It is zero in the speed of 6 lower end of chain and connected place's chain of bottom plate 3 when raw mobile, the speed etc. relative to first movement plate 2
In the speed of first movement plate 2, due to the property that chain transmits, and since 6 upper end of chain and the second movable plate 1 are connected, because
This 6 upper end fixed point of chain is equal in magnitude relative to the speed and the true velocity of first movement plate 2 of first movement plate 2, direction
It is identical.Therefore the speed of the second movable plate 1 is 2 times of 2 speed of first movement plate, therefore drive first movement plate 2 to send out in oil cylinder 8
In the same time of raw movement, the second movable plate 1 is moved with the speed operation of 2 times of first movement plates 2 and with first movement plate 2
Direction is identical, therefore the second movable plate 1, when being translatable, the length extended can be 2 extension elongation of first movement plate
Twice.Therefore, single layer panel assembly of the device of the invention relative to identical size, can extend longer distance, and nothing
It need to be realized by way of increasing system overall dimensions.
A preferred embodiment of the invention, with reference to Fig. 2, it is preferable that the second movable plate 3 is also frame structure
Plate is connected between two frames of the second movable plate 1 along its length by multiple supporting rods.The supporting rod passes through rivet
Or screw is fixed in the frame rails of first movement plate 2 or the second movable plate 1.First movement plate and the second movable plate are arranged
It can play the role of alleviator weight for frame structure.
The present invention's realizes that the device of two movement linkages can be with simple device by the flat of single oil cylinder using single cylinder
The dynamic translation for decompositing two movement parts being connected, and the speed of two movement parts has fixed relationship, solves single layer
Device leads to the problem of distance of stretch out and draw back deficiency because of size limitation, and the device of the invention is compact-sized, easily controllable, flexibility
By force, have many advantages, such as using easy, strong applicability.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.
