[0023] The mounting shaft 3 has a mounting cavity 16 at its top. A drive shaft 17, with one end extending into the rectangular hole 11, is movably mounted on the bottom wall of the mounting cavity 16. A third bearing is fixedly mounted on the bottom wall of the mounting cavity 16. The drive shaft 17 is rotatably connected to the bottom wall of the mounting cavity 16 through the third bearing. A first bevel gear 18 is fixedly mounted on the top of the drive shaft 17.

A pull ring 226 is fixedly installed on the left side of the connecting rod 224.

[0026] In use, the device is placed in a high-traffic area. The servo motor 91, activated by an external controller, rotates the worm gear 93, which in turn rotates the mounting shaft 3 and the advertising display board 7 via the worm wheel 94. This expands the display area and enhances the advertising effect. When the advertising display board 7 needs to be replaced, pulling the pull ring 226 to the left moves the connecting rod 224, slider 222, and limit block 223 to the left, causing the limit block 223 to move out of the limit groove 21, thus releasing the position restriction on the drive shaft 17. At this point, the device can be used... Turning the handwheel 204 drives the rotating shaft 201 and the third bevel gear 202 to rotate, which in turn drives the transmission shaft 17 and the first bevel gear 18 to rotate via the fourth bevel gear 203. Then, the second bevel gear 19 drives the threaded rod 13 to rotate. During the rotation of the threaded rod 13, the two positioning blocks 15 will move relative to each other, so that the two positioning blocks 15 will move out of the two positioning slots 14 respectively, thereby releasing the fixation between the two connecting blocks 6 and the mounting block 4. At this time, the advertising display board 7 can be lifted up to remove it, which facilitates the replacement of the advertising display board 7.

[0027] In summary, this automatic rotating advertising display board moves the connecting rod 224, slider 222, and limiting block 223 to the left by pulling the pull ring 226, causing the limiting block 223 to move out of the limiting groove 21, thereby releasing the position restriction on the transmission shaft 17. At this point, turning the handwheel 204 rotates the rotating shaft 201 and the third bevel gear 202, which in turn drives the transmission shaft 17 and the first bevel gear 18 to rotate via the fourth bevel gear 203, and then the second bevel gear 19 drives the threaded rod 13 to rotate. During the rotation of the threaded rod 13... This will cause the two positioning blocks 15 to move relative to each other, so that the two positioning blocks 15 can be moved out of the two positioning slots 14 respectively, thereby releasing the fixation between the two connecting blocks 6 and the mounting block 4. At this time, the advertising display board 7 can be lifted up to remove it, thus achieving the purpose of easy disassembly of the display board, and making it convenient to replace the advertising display board 7. This solves the problem that in the actual use of existing advertising display boards, since most of the display boards are fixed by bolts, it is not easy to disassemble the display board, and therefore it is not easy to replace the display board.
