[0058] In a further embodiment, a protective shell 51 is disposed on the outer side of the motor 52 , and the protective shell 51 is fixedly connected to the top of the frame 1 .

[0059] The working principle of the present invention is as follows: when it is necessary to assemble and install several display screens 8 inside the frame 1, first, align the third protrusion 81 at the top of the display screen 8 with the first card slot 12 on the inner top wall of the frame 1, and slide the third protrusion 81 into the inner wall of the first card slot 12. At the same time, align the third card slots 83 on both sides of the display screen 8 with the second protrusion 14 on the inner side wall of the frame 1 and the fourth protrusions 91 on both sides of the connecting frame 9, respectively, so that the second protrusion 14 and the fourth protrusion 91 are embedded in the third card slot 83, so that the display screen 8 is installed on the top of the inner wall of the frame 1. Then, align the second card slot 82 at the bottom of the display screen 8 with the first protrusion 13 on the inner bottom wall of the frame 1, so that the first protrusion 13 is embedded in the second card slot 82, so that the display screen 8 is installed on the bottom of the inner wall of the frame 1. Through this operation, multiple display screens 8 can be quickly and stably assembled and installed inside the frame 1, which greatly saves installation time and labor costs, and is convenient for maintenance personnel to remove it from the frame 1 for repair or replacement, thereby improving the maintainability of the equipment.

[0060] When cleaning is required, the motor 52 is started, and its output shaft drives the screw rod 53 to rotate. The rotation of the screw rod 53 causes the slider 54 to move downward along the screw rod 53. While the slider 54 moves, it drives the scraper 55 to scrape the surface of the protective glass 4, so that the scraper 55 scrapes away the dust and impurities on the surface of the protective glass 4, thereby ensuring the stability and consistency of the cleaning effect, thereby ensuring that the display effect of the display screen 8 is not affected, so that the device can adapt to various different use environments, and improve the applicability of the device;

[0061] During the operation of the device, heat is generated inside the device. At this time, the exhaust fan 62 is started, and the exhaust fan 62 quickly discharges the hot air inside the device to the outside of the device through the heat dissipation pipe 61, thereby reducing the temperature inside the frame 1, achieving the purpose of heat dissipation, and keeping the inside of the device in a suitable temperature range. When the exhaust fan 62 draws out the hot air inside the frame 1, the outside air is sucked into the frame 1 through the two L-shaped air inlets 63 at the bottom of the frame 1, thereby forming an air circulation, further improving the heat dissipation efficiency, and the filter plate 64 can effectively filter out impurities such as dust in the air, preventing these impurities from entering the device and causing damage to precision components such as the display screen 8, thereby extending the service life of the equipment.
