Digital media propaganda device

Abstract

The invention discloses a digital media propaganda device which comprises a base, tow hooks, pin holes and moving wheels, the tow hooks are fixed to the two side walls of the base, the pin holes are formed in the tow hooks, the moving wheels are arranged at the bottom end of the base, threaded sleeves are installed on one sides of the pin holes, threaded rods are installed in the threaded sleeves, and the threaded rods are connected with the tow hooks. And a rocking handle is fixed at the upper end of the screw rod. The device has the beneficial effects that by arranging a motor, a connecting shaft, dust shielding cloth, a magnetic plate and a magnetic strip, when it is rainy, the motor is controlled to act by operating a key, then the motor drives the connecting shaft to rotate to release the dust shielding cloth, the dust shielding cloth is fixed through attraction of the magnetic plate and the magnetic strip, and then rainwater is blocked; and meanwhile, when the device is not used, the dust shielding cloth can also prevent dust of the propaganda screen, the follow-up propaganda effect of the propaganda screen is guaranteed, and the practicability of the device is improved.

Problems solved by technology

[0003] However, the existing digital media publicity devices need to be publicized outdoors during the publicity process. When encountering rainy days, because the publicity screen is exposed, it is easy to cause water to enter the publicity screen and affect the subsequent use of the device. At the same time, when the device is idle Due to the large size of the device, it is not convenient to dustproof it, resulting in more dust attached to the publicity screen and affecting the follow-up publicity effect of the device. Invariant and brighter, it is easy to irritate the viewer's eyes at night, cause discomfort, and affect the performance of the device. In addition, the existing digital media publicity device is used in the publicity process due to the battery pack or the connection of the power cord. For power supply, but due to the limited power storage of the battery pack and the need for long connecting wires when using the connecting wires, which leads to inconvenient wiring, which will eventually affect the battery life and publicity time of the device, and reduce the functionality of the device, so a digital media publicity is urgently needed devices to solve existing problems
