Description

Technical Field

[0001] The utility model relates to the technical field of LED digital large screens, in particular to an LED digital large screen with a protective structure. Background Art

[0002] LED digital screen is a display method that controls semiconductor light-emitting diodes. It is generally composed of many small lights, usually red, green and blue, and the characters are displayed by turning the lights on and off. It is used to display text, graphics, images, animations, market conditions, videos, video signals and other information. It is widely used in conference speeches, advertising and other fields.

[0003] After searching, the patent publication number CN217767745U discloses an LED digital large screen with a protective structure, including a fixed base, a support frame fixedly installed on the top of the fixed base, a digital large screen shell fixedly installed on the top of the support frame, and first protective mechanisms fixedly installed on both sides of the digital large screen shell. The utility model is an LED digital large screen with a protective structure. By setting four second protective mechanisms, the buffer plate transmits the collision force inward, the buffer plate squeezes the second telescopic rod, the second telescopic rod performs telescopic movement, and the sliding block slides along the sliding groove at the same time. When the sliding block slides, the reset spring is pulled from one side, and the sliding block drives the angle rod to deflect at an angle. The angle rod squeezes the shock-absorbing spring from one side, and the buffer spring and the shock-absorbing spring both undergo elastic deformation to buffer the collision force. The four second protective mechanisms perform anti-collision protection from the four sides of the display screen to avoid damage to the display screen after being hit by external force, thereby extending the service life of the digital large screen.

[0004] However, this patent still has some shortcomings. In actual use, this patent can only provide buffering protection for the large digital screen shell on the display screen, while the most fragile screen part of the display screen does not have a protective function. There are certain deficiencies in protective performance. When transporting or not in use, the screen is exposed to the outside for a long time and is easily damaged when hit by foreign objects. The screen will also be contaminated with dust, affecting the clarity during playback.

[0005] To this end, we proposed a LED digital screen with a protective structure. Utility Model Content
