[0002] Nowadays, with the advancement and development of technology, advertising formats are also diverse, including television advertising, internet advertising, LED outdoor advertising, and so on. LED large screen outdoor advertising is favored by many advertisers because of its large media area, wide reach, and high exposure. The surrounding environment and pedestrian traffic of the location of LED large screen outdoor advertising are very important, such as busy intersections, squares of large shopping malls, industrial parks, and near residential buildings. LED outdoor advertising has become a beautiful sight in the city.

[0003] Currently, LED outdoor advertising mainly relies on display screens. However, existing LED advertising devices typically use screws and fasteners to fix the display screens during installation. Some advertisements use modular displays, and the display screens are usually vertically oriented. Some advertisements require a wider horizontal range for better display, but existing display screens often cannot be repositioned after fixing. Their single orientation is not conducive to expanding the display range of the advertisement. Therefore, an LED advertising device has been proposed. Summary of the Invention

[0020] Example 1:

[0021] Referring to Figures 1-4, this utility model provides a technical solution: an LED advertising device, including a horizontal base 1, two vertical bases 2, and a base plate 16. Two first threaded blocks 3 are disposed inside the two vertical bases 2. A rotating cylinder 4 is rotatably connected to the outer surface of each first threaded block 3. A gear 5 is fixedly sleeved on the outer surface of the rotating cylinder 4. An L-shaped mounting plate 8 is fixedly connected to the outer surface of each first threaded block 3. A first electric push rod 9 is fixedly mounted on the outer surface of the L-shaped mounting plate 8. A rack 10 is fixedly mounted on the output end of the first electric push rod 9, and the rack 10 engages movably with the outer surface of the gear 5. A mounting plate 6 is fixedly connected to the outer surface of the rotating cylinder 4, and a display screen 7 is mounted on the outer surface of the mounting plate 6. Specifically, the first electric push rod 9 drives the rack 10 to move by a distance L, where L = π * d / 4, and d is the diameter of the gear 5. The rack 10 drives the gear 5 to rotate, the gear 5 drives the rotating cylinder 4 to rotate, and the rotating cylinder 4 drives the mounting plate 6 to rotate the display screen 7 by ninety degrees. Then, through the operation of the first motor 12 and the second motor 15, the four display screens 7 are spliced ​​to a suitable position, so that the four vertically set display screens 7 can be rotated into four horizontally set display screens, which facilitates the display of advertisements.

[0022] In this embodiment, a first positive and negative lead screw 11 is rotatably connected inside the horizontal seat 1, and a first motor 12 is fixedly installed on the outer surface of the horizontal seat 1. The output end of the first motor 12 is fixedly connected to the first positive and negative lead screw 11. Two second threaded blocks 13 are threadedly connected to the outer surface of the first positive and negative lead screw 11. The two vertical seats 2 are fixedly connected to the two second threaded blocks 13 respectively. Specifically, the first motor 12 drives the first positive and negative lead screw 11 to rotate, thereby moving the two second threaded blocks 13 and adjusting the spacing between the left and right display screens 7.

[0023] In this embodiment, a second positive and negative lead screw 14 is rotatably connected inside the vertical seat 2, and two first threaded blocks 3 are threadedly connected to the outer surface of the second positive and negative lead screw 14. A second motor 15 is fixedly installed on the top outer surface of the vertical seat 2, and the output end of the second motor 15 is fixedly connected to the second positive and negative lead screw 14. Specifically, the second motor 15 drives the second positive and negative lead screw 14 to rotate, thereby moving the two first threaded blocks 3 and adjusting the spacing between the upper and lower display screens 7.

[0024] In this embodiment, a top plate is fixedly connected to the bottom outer surface of the horizontal base 1, and a second electric push rod 17 is fixedly installed on the top outer surface of the base plate 16. The output end of the second electric push rod 17 is fixedly connected to the top plate. Specifically, the overall height of the display screen 7 after installation is adjusted by the operation of the second electric push rod 17.

[0025] In this embodiment, telescopic columns are fixedly connected to the top four corners of the base plate 16. The top of the telescopic columns is fixedly connected to the bottom four corners of the top plate. Specifically, the base plate 16 is supported by the telescopic columns.

[0026] In this embodiment, a first waist hole is provided at each of the four corners of the base plate 16, and a side plate 18 is fixedly connected to the side of the base plate 16. A second waist hole is provided on the outer surface of the side plate 18. Specifically, when installing the device, the device is installed on the horizontal plane through the first waist hole on the base plate 16, and the device is installed on the vertical plane through the second waist hole on the side plate 18, so that different installation methods can be selected according to actual needs.

[0027] Working Principle: In use, this utility model projects advertisements onto the display screen 7. When the display range of the display screen 7 needs to be adjusted, the vertical display screen 7 is rotated to a horizontal position. At this time, the first motor 12 rotates the first positive and negative lead screw 11, driving the two second threaded blocks 13 to move, thereby adjusting the distance between the two vertical seats 2, and thus adjusting the distance between the left and right display screens 7. Then, the second motor 15 drives the second positive and negative lead screw 14 to rotate, adjusting the distance between the two first threaded blocks 3, thereby adjusting the position of the upper and lower display screens 7. The first electric push rod 9 drives the rack 10 to move, with a moving distance of L, where L = π*d / 4, and d is the diameter of the gear 5. The rack 10 drives the gear 5 to rotate, the gear 5 drives the rotating drum 4 to rotate, and the rotating drum 4 drives the mounting plate 6 to rotate the display screen 7 by 90 degrees. Then, through the operation of the first motor 12 and the second motor 15, the four display screens 7 are spliced ​​to a suitable position, thereby rotating the four vertically set display screens 7 into four horizontally set ones, which facilitates the display of advertisements.

[0028] When installing the device, it is installed on a horizontal surface through the first waist hole on the base plate 16, and on a vertical surface through the second waist hole on the side plate 18, so that different installation methods can be selected according to actual needs.
