[0019] The present invention will be further described below with reference to the embodiments.

[0020] See also Figure 1-4 The utility model provides a multi-layer combined plastic hollow panel, including a plastic hollow panel body 1, first guard plates 2 are fixed on both sides of the top of the plastic hollow panel body 1, the inner wall of the first guard plate 2 is provided with a limited movable groove 3, the inner wall of the limited movable groove 3 is slidably installed with a second guard plate 4, the top of the second guard plate 4 is fixed with a connecting plate 5, and limited blocks 6 are fixed on both sides of the bottom end of the second guard plate 4.

[0021] The lifting mechanism 9 can mainly drive the lifting column 96 to move, thereby lifting the upper plastic hollow plate body 1, thereby increasing the distance between the two plastic hollow plate bodies 1, making its practicality more outstanding.

[0022] Further as Figure 3 As shown, it is worth mentioning that the lifting mechanism 9 includes a servo motor 91, which is fixedly mounted on the inner wall of the bottom end of the rotating groove 10.

[0024] Further Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that the top ends of the two lifting columns 96 are respectively fixed to both sides of the top of the connecting plate 5.

[0025] This solution has the following working process: in order to improve the practicality of the plastic hollow plate body 1, first align the supporting leg 7 at the bottom of the other plastic hollow plate body 1 with the corresponding lifting column 96, and then limit the lifting column 96 to the inner wall of the engaging groove 8, so that it can connect the two plastic hollow plate bodies 1 and limit the plastic hollow plate body 1 at the same time. In order to increase the spacing between the two plastic hollow plate bodies 1, the servo motor 91 is started to drive the driving gear 92 to rotate, and further drive the driven gear 93 to rotate at the same time, thereby driving the threaded screw 94 to rotate at the same time. When the threaded screw 94 rotates, it can drive the connecting bracket 95 to limit the movement, thereby driving the lifting column 96 to move, thereby achieving the jacking effect, and further driving the supporting leg 7 to be force-bearing, thereby driving the plastic hollow plate body 1 to be force-lifted.

[0026] According to the above working process, it can be known that: while the jacking column 96 is jacking, it can also drive the connecting plate 5 to move at the same time, thereby driving the second guard plate 4 to perform limiting movement, thereby improving the protective effect of the plastic hollow board body 1.

[0031] The bottom of the support leg 7 is provided with a snap-fitting groove 8 , which can be snap-fitted with the jacking column 96 and the connecting plate 5 , thereby improving the positioning effect between the two plastic hollow plate bodies 1 .

[0032] In summary: the jacking mechanism 9 can mainly drive the jacking column 96 to move, thereby lifting the upper plastic hollow plate body 1, thereby increasing the distance between the two plastic hollow plate bodies 1, making its practicality more outstanding. At the same time, when the jacking column 96 is lifting, it can also drive the connecting plate 5 to move, thereby driving the second guard plate 4 to limit the movement, thereby improving the protective effect of the plastic hollow plate body 1.
