Embodiment
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
Provided by Fig. 1 to Fig. 6, the present invention includes bottom plate 1, there are the shelf 2 for being fixed on bottom plate 1, shelf in the top of bottom plate 1
There is the portable plate 3 that can be moved up and down between bottom plate 1 and shelf 2 under 2, the top of bottom plate 1 has on multiple cylinders 4, cylinder 4
Provided with boss, the cylinder 4 above boss runs through portable plate 3 and shelf 2, and constituting cylinder 4 can be in portable plate 3 and shelf
The structure slided up and down on 2;Thrust spring 5 is set with cylinder 4 below boss, upper end and the boss of thrust spring 5 connect
Touch, lower end is contacted with bottom plate 1, constitute the structure that cylinder 4 is moved up and down through thrust spring 5;
Equipped with the multiple contiguous blocks 6 for being placed in the lower section of portable plate 3 on portable plate 3, contiguous block 6 is provided with pre-and post perforative straight trough 7, directly
Groove 7 is built with sliding rotating shaft 8, and multiple sliding rotating shafts 8 are interconnected to constitute in STATEMENT OF FEDERALLY SPONSORED, sliding rotating shaft 8 and are set with connecting rod 9, many
Individual connecting rod 9 is be arranged in parallel, and one end and the bottom plate 1 of connecting rod 9 are hinged, and one in multiple connecting rods 9 is connected with action bars 10, is constituted many
The structure that individual connecting rod 9 rotates in same direction through action bars 10 and STATEMENT OF FEDERALLY SPONSORED on bottom plate 1.
In order that the present invention reaches more preferable using effect, the upper surface and the upper surface of shelf 2 of described cylinder 4
The distance between be less than the distance between upper surface of lower surface and bottom plate 1 of cylinder 4;The lower surface of described cylinder 4
It is not more than the height of thrust spring 5 when thrust spring 5 compresses completely with the distance between the lower surface of portable plate 3.
In order that portable plate 3 and the cylinder 4 of the present invention reach preferably linkage effect, the upper end of described portable plate 3
When face is contacted with the lower surface of shelf 2, the upper surface of the boss on cylinder 4 is contacted with the lower surface of portable plate 3, thrust bullet
Spring 5 is in the critical condition before compressive state or compression.
In order that the present invention reaches more preferable using effect, the upper surface of described cylinder 4 is provided with anti-slip veins.
The present invention is in use, place items within shelf 2, because every group of cylinder 4 and thrust spring 5 are all independent
Coordinate, therefore, according to the contact area of article and shelf 2, the cylinder 4 in the areal extent is simultaneously by the gravity of article
Effect and slide downward and compress thrust spring 5, the top of the cylinder 4 outside the areal extent keeps stretching out in shelf 2
Top, stops so as to be formed to horizontal displacement of the article on shelf 2;The upper surface of cylinder 4 is provided with anti-slip veins, it is ensured that
Frictional force increase between cylinder 4 and article, article will not produce horizontal displacement easily;Simultaneously as thrust spring 5 is in
Upwards thrust during compressive state makes the upper surface of cylinder 4 be contacted with the real-time extruding of article, and article is produced in transportation
Certain cushioning effect can be played when jolting and falling.
When article needs to unload, using power set or manual pull joystick 10, the drivening rod 9 of action bars 10 is set to exist
Circular-rotation counterclockwise is done on bottom plate 1 along jointed shaft, the circular-rotation of connecting rod 9 drives remaining connecting rod 9 simultaneously through STATEMENT OF FEDERALLY SPONSORED
Do circular-rotation in the same direction;The one end being connected on connecting rod 9 with contiguous block 6 is movable end, and the circular-rotation of the movable end is decomposed into
Translational motion along the length direction of straight trough 7 and the linear motion perpendicular to straight trough direction, translational motion make the movable end with connecting rod 9
Connected sliding rotating shaft 8 is slided to the left in straight trough 7, and linear motion makes what is be connected through sliding rotating shaft 8 and contiguous block 6 with connecting rod 9
Portable plate 3 moves linearly to the direction of bottom plate 1;The linear motion of portable plate 3 makes portable plate 3 be contacted and through boss band with boss extruding
Dynamic cylinder 4 is slided on shelf 2 to the direction of bottom plate 1, while thrust spring 5 is compressed;
When the slide downward of cylinder 4 makes the upper surface of cylinder 4 be moved to concordant with the upper surface of shelf 2, cylinder 4
Barrier effect is no longer produced to article, now the article on shelf 2 can remove unloading, or tilting shelf slides article
Fall.
After article is unsnatched, the active force on action bars 10 is removed, under the thrust of the thrust spring 5 compressed,
Cylinder 4 moves up and drives portable plate 3 through boss while moving up, and the movement of portable plate 3 makes through contiguous block 6 and sliding
The connecting rod 9 that rotating shaft 8 is connected with portable plate 3 is produced to reset and rotated, when portable plate 3 is moved to the lower end of its upper surface and shelf 2
When face is contacted, portable plate 3, cylinder 4, thrust spring 5, connecting rod 9 are completed to reset and no longer moved, and now action bars 10 is with connecting rod
9 reset together.
In reseting procedure, applying certain active force to action bars 10 rotates clockwise it, can make above-mentioned resetted
Journey reaches more preferable effect.
According to different use environments and requirement, conversion is adjusted by the arrangement mode to cylinder 4, it is ensured that no
When the article of same specification or its optional position being packaged on shelf 2 are placed, by reliable fixation it can be made not occur water
Prosposition is moved.
Clever structure of the present invention, simple operation, only action bars, which need to be controlled, can complete the spacing and spacing of article
Release, not only increase safety during goods transportation, also save the manpower fixed in loading process required for article position and
Material resources, greatly improve the efficiency of goods transportation, reduce human cost, and safe thing when can be prevented effectively from artificial fixed
Therefore, the transport when article individual layer that is particularly suitable for use in is loaded.Simultaneously as upwards thrust during thrust spring compression, makes article exist
Jolting for being produced in transportation can be buffered effectively, and the integrality of article is protected to a certain extent.
