DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figs. 1-3 The present invention relates to an LED display advertising machine, comprising a base plate 1, on the upper part of which a first LED display 2 is mounted for displaying advertising content to a crowd on a flat surface. Several support plates 3 are provided on the right side of the first LED display 2, and a second LED display 4 is rotatably connected to it via a pivot.

[0023] The second LED display screen 4 is rotatably mounted via a pivot and a support plate 3. Several first fixing plates 5 are located on the right side of the second LED display screen 4, each with a first threaded hole. Each of these first threaded holes is threaded with a first bolt 6. One end of each first bolt 6 is threaded with a support device to support the second LED display screen 4 at a certain tilt angle. The support device is mounted on the first fixing plate 5 via the threaded connection between the first bolts 6 and the first threaded holes. Each support device includes a first telescopic plate 11, and each first telescopic plate 11 has a slot into which a second telescopic plate 12 is inserted. Each of the two telescopic plates 12 is provided with several fourth threaded holes, and the right side of each of the several first telescopic plates 11 is provided with a fifth threaded hole, and each is threadedly connected with a fifth bolt 13. The left side of each of the several fifth bolts 13 is threadedly connected to a fourth threaded hole. By unscrewing the fifth bolts 13 from the fifth threaded holes of the first telescopic plates 11, the extension length of the first telescopic plates 11 and the second telescopic plates 12 can be adjusted. Then, by screwing the fifth bolts 13 into the fifth threaded holes of the first telescopic plates 11 and the fourth threaded holes of the second telescopic plates 12, the first telescopic plates 11 and the second telescopic plates 12 are fixed at the extension length. The right side of the base plate 1 is provided with a sliding groove and is slidably connected to... The moving device includes several sliding plates 7, each sliding within a corresponding groove. A second threaded hole is provided at the front of the base plate 1, and a second bolt 8 is threadedly connected thereto. The sliding plate 7 at the front is provided with a third threaded hole, and is threadedly connected to the second bolt 8. The sliding plate 7 is slid out of the groove of the base plate 1 a certain distance, and then the second bolt 8 is screwed into the second threaded hole of the base plate 1 and into the third threaded hole of the sliding plate 7, fixing the sliding plate 7 to the base plate 1. A connecting plate 9 is provided on the right side of each of the sliding plates 7. A rotating plate 10 is rotatably connected to the middle of the connecting plate 9 via a pivot. The upper part of the rotating plate 10 is connected to the lower part of several supporting devices. Next, the support device rotates by rotating the rotating plate 10 at the connecting plate 9, thereby adjusting the tilt angle of the support device. The front part of the connecting plate 9 is provided with a sixth threaded hole and is threaded with a sixth bolt 14. The front part of the first telescopic plate 11 located at the front is provided with a seventh threaded hole and is threaded with the sixth bolt 14. The sixth bolt 14 is screwed into the sixth threaded hole of the connecting plate 9 and the seventh threaded hole of the first telescopic plate 11, thereby fixing the first telescopic plate 11 at the tilt angle and fixing the second LED display screen 4 at the tilt angle. Several brake wheels are provided at the lower part of the base plate 1 and the connecting plate 9 to facilitate the movement of the device.

[0024] In summary, when using this LED display advertising machine, the operator pushes the device to a designated location on the first floor of the shopping mall. Then, the sliding plate 7 slides a certain distance within the groove of the base plate 1, aligning the second threaded hole of the base plate 1 with the third threaded hole of the sliding plate 7. Next, the second bolt 8 is screwed into the second and third threaded holes to fix the sliding plate 7 to the base. Then, the second LED display 4 is rotated to a horizontal position. Next, the first telescopic plate 11 is rotated so that the upper part of the second telescopic plate 12 supports the lower part of the second LED display 4. The sixth bolt 14 is then screwed into the sixth threaded hole of the connecting plate 9 and the seventh threaded hole of the first telescopic plate 11, thereby fixing the second LED display 7 to the base. One telescopic plate 11 is fixed at the tilt angle. Then, the fifth bolt 13 is unscrewed from the fifth threaded hole of the first telescopic plate 11. The extension lengths of the first telescopic plate 11 and the second telescopic plate 12 are adjusted so that the upper part of the second telescopic plate 12 coincides with the first fixed plate 5. The first bolt 6 is screwed into the first threaded hole of the first fixed plate 5 and then screwed into the upper part of the second telescopic plate 12. After the two are installed together, the fifth bolt 13 is finally screwed into the fifth threaded hole of the first telescopic plate 11 and the fourth threaded hole of the second telescopic plate 12. The first telescopic plate 11 and the second telescopic plate 12 are then fixed together, and the first LED display screen 2 and the second LED display screen 4 can be turned on to display advertisements.
