Example one

As shown in fig. 1 to 6, a folding system of a base plate and rail combination structure according to a preferred embodiment of the present invention includes an extension rail 1, an extension base plate 2, a fixed base plate 5, a sinking base plate 6, a linkage mechanism and a hydraulic cylinder 9, wherein a lower portion of the extension rail 1 and an upper portion of the extension base plate 2 are rotatably connected to form a set of extension mechanism, and the linkage mechanism is connected among the extension rail 1, the extension base plate 2, the fixed base plate 5 and the hydraulic cylinder 9 to convert a linear motion of the hydraulic cylinder 9 into an unfolding or folding motion of each component in the system.

When the folding system is folded and contracted, each extending bottom plate 2 is upwards and inwards recycled, the left supplementing beam 3 and the right supplementing beam 4 are simultaneously driven, the connecting element enables the horizontal left supplementing beam 3 and the horizontal right supplementing beam 4 to be inwards bent along the connecting edge when the folding system is unfolded, and the left supplementing beam 3 and the right supplementing beam 4 are inwards folded and extend into a cylindrical body surrounded by the extending bottom plates 2.

A sinking bottom plate 6 is arranged in the middle of the fixed bottom plate 5, and the sinking bottom plate 6 forms a depression in the middle of the fixed bottom plate 5.

The extension railing 1 is a polygonal frame structure composed of a lower rectangular frame and an upper trapezoidal frame, the lower portion of the extension railing is provided with a stable rectangular structure, the upper portion of the extension railing is trapezoidal due to the fact that the upper portion of the extension railing does not interfere with the upper portion of the extension railing at the top, and oblique angles of two side edges of each trapezoid are determined by the number of groups of extension mechanisms: when the device consists of eight groups of stretching mechanisms, the bevel angle is preferably about 110 degrees; when the device consists of four groups of stretching mechanisms, the bevel angle is preferably about 130 degrees. The fixed bottom plate 5 is a regular polygon frame structure, and the number of the sides of the fixed bottom plate 5 is consistent with the number of the groups of the stretching mechanisms.
