Technical Field

[0001] The utility model relates to the technical field of slide rail screens, in particular to a slide rail screen. Background Art

[0002] The sliding screen is mainly composed of customized sliding rails, infrared sensors, televisions, computers, light boxes, etc. The rails are used to fix the LCD TV to slide, so that when the TV slides, videos related to the wall pictures can be displayed on the TV. The interactive sliding screen has two sliding methods, one is to push the screen by hand, and the other is automatic sensing sliding. Both methods can be customized according to specific usage needs.

[0003] After searching, the Chinese utility model patent document with patent number CN210241125U discloses a slide rail screen. Although the structure of the device is reasonably set, baffles made of synthetic rubber material are set at the left and right ends of the upper and lower slide rails to reduce the impact force and avoid collision with the outer frame structure. It can also reduce the vibration and better protect the equipment. At the same time, protective structures are set at the upper and lower ends of the LCD screen to protect the outer frame of the LCD screen, and a ball structure is set between the protective structure and the wall. On the one hand, it avoids mutual wear and tear, and on the other hand, it helps the overall sliding of the LCD screen, which is more convenient. However, during use, the maintenance of the slide rail requires manual addition of lubricating grease, and the slide rail screen needs to be disassembled.
