Embodiment 1
[0022] refer to Figure 1-8 , a revolving door display board, including a publicity page 3, connecting rings 4 are symmetrically installed at the upper and lower ends of the publicity page 3, the publicity page 3 includes a plurality of display boards 6, and a rotating shaft 7 is fixedly inserted on the display board 6, and the publicity page 3 Connecting rings 4 are installed at the upper and lower ends, and the two ends of the rotating shaft 7 are rotatably connected with the connecting ring 4. A base 1 is installed below the publicity page 3, and a support column 2 is rotatably connected to the base 1. A pair of support columns are installed on the support column 2. mechanism, the two supporting mechanisms are respectively installed in the two connecting rings 4, each supporting mechanism includes four supporting shafts 5, each supporting shaft 5 is composed of two folding shafts, the two folding shafts are connected in rotation, and one of the folding shafts It is rotatabl...
Embodiment 2
[0026] Fold the opposite supporting shafts 5 in half, that is, the two folding shafts are rotated and folded with each other, and the connecting ring 4 on one side will be drawn closer during the folding of the shafts, wherein the connecting ring 4 uses a memory metal with good ductility, and then The circular connecting ring 4 is shrunk into a rectangular state, and the display board 6 installed on the connecting ring 4 will be flattened at this moment, displaying a plane pattern and achieving a plane publicity and display effect.
Embodiment 3
[0028] If there is wind outdoors, the display board 6 on the side facing the wind will be subjected to wind force, and the force of the wind on the display board 6 will make the display board 6 rotate, and the display board 6 will drive the rotating shaft 7 and the stop block 9 to rotate accordingly , the cotton 10 is very light, and it is easily compressed by force, causing the display board 6 to shift to one side, and one side of the second display surface 11 will directly face the outside, presenting a structure similar to a fan, and the display board is continuously subjected to wind force 6. The display board 6 on the offset side is subjected to a large wind force, resulting in unbalanced force on each position of the display board 6, and the display board 6 will move due to unbalanced force, and the support column 2 and the base 1 are connected by rotation , the force of the wind on the display board 6 will drive the entire publicity page 3 to rotate;
