[0012] 1. The utility model is provided with a film mask on the outside of the screen, which can be used to block most of the dust. At the same time, the film mask can be moved by winding around the winding roller, so that the first scraper plate and the second scraper plate can be used for scraping, so that the dust on the outer surface of the film mask can be automatically scraped and cleaned to ensure the cleanliness of the film mask and facilitate seeing the screen clearly. This is not only convenient to clean but also will not damage the screen.

[0013] 2. The utility model is easy to use, and the upper and lower sealing of the film mask can be improved through the L-shaped limit plate, thereby preventing dust from entering through the upper and lower gaps between the film mask and the display screen body, thereby further improving the protection effect of the device.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-7 The utility model provides a technical solution: a LED display screen mask, including a display screen body 1, a screen 2 is fixedly arranged in the middle of the surface of the display screen body 1, and protective mechanisms for protecting the screen 2 are arranged on both sides of the display screen body 1, and the protective mechanisms include a storage bin 3, a winding roller 4, a film mask 5, a first scraper 6, a fixed plate 7, and a second scraper 8. Storage bins 3 are fixedly arranged on both sides of the surface of the display screen body 1, and a winding roller 4 is movably arranged inside the storage bin 3 through a rotating shaft. A film mask 5 is wound on the outer surface of the winding roller 4, and a first scraper 6 is embedded on both sides of the surface of the display screen body 1. A fixing plate 7 is fixedly arranged on one side of the first scraper 6 on the surface of the display screen, and a second scraper 8 is fixedly arranged on the outer surface of the fixing plate 7.

[0024] The first scraper plate 6 and the second scraper plate 8 are clamped on the outer surface of the film mask 5. By clamping the first scraper plate 6 and the second scraper plate 8 on the outer surface of the film mask 5, the outer surface of the film mask 5 can be scraped and cleaned when the film mask 5 moves, thereby ensuring the cleanliness of the film mask 5 and making it convenient to see the screen 2 clearly.

[0025] The lower end of the storage bin 3 is fixedly provided with a motor 10, and the output shaft end of the motor 10 is transmission-connected to the rotating shaft of the winding roller 4 through a coupling, and the motor 10 can conveniently drive the winding roller 4 to rotate, so as to drive the film mask 5 to move. It should be noted that when one winding roller 4 is winding the film mask 5 when the device is used, the other winding roller 4 should be rotated to release the film mask 5, so as to achieve the purpose of moving the film mask 5;

[0026] A bracket 11 is fixedly provided at the lower end of the display screen body 1, and the bracket 11 can provide a stable supporting force for the entire device;

[0027] The film mask 5 is arranged at the front end of the screen 2, so that the film mask 5 can protect the screen 2 and prevent most dust from contacting the screen 2; and when in use, the two winding rollers 4 should be driven by the motor 10 to rotate to tighten the film mask 5 so that the film mask 5 can be closely attached to the surface of the display screen body 1, so as to better play the role of dust prevention;

[0028] The film mask 5 is made of a transparent film material, which can ensure that the user can see the screen 2 clearly through the film mask 5;

[0029] The upper and lower ends of the outer surface of the display body 1 are fixedly provided with L-shaped limit plates 9, and the L-shaped limit plates 9 are engaged with the outer surface of the film mask 5. The L-shaped limit plates 9 can improve the sealing performance of the film mask 5 from top to bottom, thereby preventing dust from entering from the upper and lower gaps between the film mask 5 and the display body 1;

[0030] Working principle: When using the device, the film mask 5 can protect the screen 2 and prevent most dust from contacting the screen 2; and when using it, the two winding rollers 4 should be driven by the motor 10 to rotate to tighten the film mask 5 so that the film mask 5 can be closely attached to the surface of the display body 1, so as to better play the role of dust prevention;

[0031] As the device is used, dust will accumulate on the surface of the film mask 5. At this time, the motor 10 can be used to drive the winding roller 4 to rotate. The winding roller 4 rotates, thereby winding and driving the film mask 5 to move. It should be noted that when the device is in use, when one winding roller 4 is winding around the film mask 5, the other winding roller 4 should be rotated to release the film mask 5, which can also achieve the purpose of moving the film mask 5. At this time, the first scraper plate 6 and the second scraper plate 8 are clamped on the outer surface of the film mask 5, and the outer surface of the film mask 5 can be scraped and cleaned when the film mask 5 moves, thereby ensuring the cleanliness of the film mask 5 and making it convenient to see the screen 2 clearly. In this way, the cleanliness of the film mask 5 is ensured, making it convenient to see the screen 2 clearly, and this is not only convenient to clean but also will not damage the screen 2.
