[0031] The LED module 11 is installed on the front surface of the box frame 12, the two box frames 12 are fixedly connected to the front surfaces of the two main frames 15 by side locks 16, the two main frames 15 are rotatably connected by two folding hinges 14, the back panel 17 is fixedly connected to the rear surface of the main frame 15 by bolts, the two brackets 13 are symmetrically fixedly connected to the rear surfaces of the two back panels 17 by bolts, the rear cover 19 is fixedly connected to the rear surface of the main frame 15 located below by bolts, the power module 18 and the control module 21 are both installed on the rear surface of the main frame 15 located below, the four universal wheels 23 are symmetrically installed on the lower surface of the base 22, and the two folding hinges 14 are symmetrically installed on the rear surfaces of the two back panels 17.

[0032] In one embodiment, the lower surface of the main frame 15 located at the bottom is fixedly connected to the upper surface of the base 22, and the upper and lower main frames 15 cooperate with the LED module 11 and the box frame 12 respectively to form the upper and lower display screens of the advertising machine. The bracket 13 can limit the two main frames 15 so that the two display screens form a complete display screen.

[0033] In one embodiment, the control module 21 and the power module 18 are both located inside the back cover 19. A speaker 20 is installed on one side of the inner wall of the back cover 19. The control module 21 is composed of a single-chip microcomputer or a microprocessor, and is responsible for receiving user input, processing media files, controlling display and audio output, and realizing remote management and control of the device, mainly including functions such as device screen on / off, volume adjustment, and brightness adjustment;

[0034] The power module 18 is composed of circuits such as a transformer, a rectifier, a filter and a voltage stabilizer. It is responsible for converting the input voltage into a stable output voltage to provide the required power supply for various components of the advertising machine. It mainly includes functions such as voltage conversion, current adjustment, and power distribution.

[0035] In one embodiment, the limiting components 301 are installed on both sides of the main frame 15 at the bottom, and the limiting components 301 include two fixing seats 31, a rotating rod 32, a limiting plate 33, a rotating shaft 34, a spring 35 and an inserting rod 37;

[0036] The two fixed seats 31 are symmetrically fixedly connected to the two sides of the main frame 15 located below, one end of the rotating shaft 34 is fixedly connected to the rotating rod 32, and the other end of the rotating shaft 34 is fixedly connected to the limit plate 33. The spring 35 is sleeved on the outer wall of the rotating shaft 34, and the insertion rod 37 is fixedly connected to the rotating rod 32. The rotating shaft 34 is located inside the fixed seat 31, and the rotating shaft 34 is slidably and rotatably connected to the fixed seat 31. The limit plate 33 is pushed by the spring 35, and the limit plate 33 drives the rotating rod 32 through the rotating shaft 34, and the rotating rod 32 drives the insertion rod 37 to move toward the direction close to the main frame 15.

[0037] In one embodiment, one end of the spring 35 presses against the limit plate 33, and the other end of the spring 35 presses against the fixing seat 31. A receiving hole 38 is provided on the side of the fixing seat 31 away from the main frame 15. The insertion rod 37 is slidably connected to the inner wall of the receiving hole 38. The insertion rod 37 can be stored through the receiving hole 38, thereby limiting the position of the rotating rod 32 and fixing the position of the rotating rod 32.

[0038] In one embodiment, two limit seats 39 are symmetrically fixedly connected to both sides of the main frame 15 at the top, a socket 40 is provided on the side of the limit seat 39 away from the main frame 15, and a handle 36 is fixedly connected to the side of the rotating rod 32 away from the main frame 15. When the upper main frame 15 is folded, the insertion rod 37 is inserted into the socket 40. At this time, the position of the main frame 15 can be limited. When the advertising machine is moved, the LED module 11 is stable and no collision will occur.

[0039] When the utility model is working: the LED module 11 is powered by the power module 18, and the upper and lower main frames 15 cooperate with the LED module 11 and the box frame 12 respectively to form the upper and lower display screens of the advertising machine, and the bracket 13 can limit the two main frames 15, so that the two display screens form a complete display screen;

[0040] When folding, disconnect the power supply, remove the bracket 13, and then rotate the main frame 15 located above. The main frame 15 rotates through the folding hinge 14, and then the advertising machine can be folded. When pushing the advertising machine, the advertising machine can move through the universal wheels 23;

[0041] By pulling the rotating rod 32 through the handle 36, the spring 35 is compressed and the insertion rod 37 is moved out of the storage hole 38. Then the rotating rod 32 is rotated, and the rotating rod 32 drives the insertion rod 37 to rotate to a position corresponding to the insertion hole 40. Then the handle 36 is released and the insertion rod 37 is inserted into the insertion hole 40. At this time, under the action of the spring 35, the insertion rod 37 remains inserted into the insertion hole 40, and the positions of the two main frames 15 are relatively fixed. When moving, the advertising machine as a whole can remain stable, thereby enhancing safety during transportation.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
