[0002] Schools and public institutions generally have fixed propaganda columns. At the same time, various propaganda activities are often held outdoors such as squares according to propaganda needs. At this time, a large number of propaganda columns need to be set up. The main purpose is to create an atmosphere for the event and achieve the purpose of propaganda and display.

[0003] Existing advertising boards mainly use electronic screens and advertising paper for advertising. The cost of advertising paper is relatively low. Existing advertising paper is generally installed on the advertising surface of the advertising board by means of thumbtacks or glue. However, this installation method can only carry out single advertising and cannot switch advertising paper to achieve the effect of multiple advertising rotations. The advertising effect is poor. At the same time, when replacing the advertising paper later, this installation method requires manual removal of thumbtacks or glue, which is a tedious process and has high labor intensity. Therefore, in view of this, the existing structure and defects are studied and improved to provide a new advertising board with greater practical value. Utility Model Content

[0026] The utility model provides a new advertising column, including a column body 1, two groups of rotating shafts 13 are detachably installed in the middle of the column body 1, the two groups of rotating shafts 13 are arranged up and down, one end of the two groups of rotating shafts 13 are fixedly sleeved with synchronous wheels, a synchronous belt 18 is connected between the two groups of synchronous wheels, the other end of the upper rotating shaft 13 is provided with a driving mechanism, the outer walls of the two groups of rotating shafts 13 are jointly covered with advertising paper 8, the column body 1 is rotatably installed with a protective plate 6 near the advertising paper 8, the middle part of the protective plate 6 is provided with an observation window 7, one side of the protective plate 6 is provided with four groups of limiting mechanisms, the four groups of limiting mechanisms are arranged in pairs on one side, the limiting mechanism includes a pressure block 9 slidably installed on one side of the protective plate 6, a round pin 10 is installed on one side of the pressure block 9, the outer wall of the round pin 10 is sleeved with a spring 11 and a rectangular block 12, and the rectangular block 12 is fixedly connected to one side of the protective plate 6.

[0027] The top of the fence 1 is equipped with a rain shield 3, and two sets of brackets 4 are installed on the top of the rain shield 3. A solar panel 17 is rotatably mounted between the two sets of brackets 4. A servo motor 5 is installed on one side of one set of brackets 4. The output end of the servo motor 5 passes through one side of the bracket 4 and is connected to the solar panel 17. Multiple sets of batteries are installed on one side of the bottom of the rain shield 3, and the multiple battery sets are connected to the solar panel 17 via power cables. By providing the servo motor 5, the solar panel 17 can be rotated, thereby adjusting according to the direction of sunlight, which is highly convenient.

[0028] The driving mechanism includes a driven gear 14 mounted on the other end of the upper rotating shaft 13 , a driving gear 15 is meshed with the bottom end of the driven gear 14 , and the driving gear 15 is connected to a driving motor, which is installed inside the fence body 1 .

[0029] The observation window 7 is a transparent acrylic plate, and this design reduces the labor intensity of the user when opening the protective plate 6.

[0030] Among them, gas springs 2 are rotatably installed on the left and right sides of the fence body 1, and the other ends of the two groups of gas springs 2 are rotatably installed on the left and right sides of the protective plate 6 respectively. Multiple groups of hinges are installed on the top of the protective plate 6, and the other ends of the multiple groups of hinges are all installed on one side of the fence body 1.

[0031] Among them, four groups of T-shaped slide grooves are opened on one side of the protective plate 6, and T-shaped sliders are slidably installed in the four groups of T-shaped slide grooves. The four groups of T-shaped sliders are fixedly connected to one side of the four groups of pressure blocks 9 respectively. The bottom end of the four groups of pressure blocks 9 is provided with an arc surface. The coordinated use of the T-shaped slide grooves and the T-shaped sliders provides a guiding effect for the sliding of the pressure blocks 9.

[0032] Among them, installation grooves 16 adapted to the rotating shaft 13 are opened on both sides of the middle part of the column body 1. The installation grooves 16 are set at an inclined angle. This design facilitates the installation and disassembly of the rotating shaft 13, thereby making it convenient for the staff to replace the advertising paper 8 on the outer wall of the rotating shaft 13.

[0033] The working principle of this embodiment is as follows: during installation, the staff can install a controller on one side of the fence body 1. Later, when in use, the driving motor can be set with the controller to realize the automatic switching of the daily advertising paper 8. During this process, the driving motor drives the driving gear 15 to rotate, the driving gear 15 drives the driven gear 14 to rotate, the driven gear 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives another set of rotating shafts 13 to rotate through the synchronous wheel and the synchronous belt 18, thereby realizing the switching of the advertising paper 8;

[0034] When the advertising paper 8 needs to be removed and replaced, the staff opens the protective plate 6. During the rotation of the protective plate 6, its pressure block 9 is against the outer wall of the rotating shaft 13. The rotating shaft 13 can be lifted up to remove it, and then the rotating shaft 13 with the new advertising paper 8 is installed on the installation groove 16. Then the protective plate 6 is closed. During this process, the arc surface on one side of the pressure block 9 first contacts the outer wall of the rotating shaft 13, and then the pressure block 9 drives the round pin 10 to slide in the T-shaped slide groove, thereby squeezing the spring 11. When the protective plate 6 is completely closed, its spring 11 squeezes the pressure block 9 through elastic potential energy, thereby limiting the rotating shaft 13 through the pressure block 9, which can prevent the rotating shaft 13 from shaking.
