Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to a moisture-proof and dehumidifying steel frame structure for display screens. Background Technology

[0002] LED displays are display devices that use light-emitting diodes (LEDs) as display pixels, and are widely used in indoor and outdoor advertising, information dissemination, stage performances, and sporting events. Due to their advantages such as high brightness, low power consumption, vibrant colors, and long lifespan, LED displays have become an important component of current electronic display technology. In practical applications, LED displays typically require a steel frame structure for installation and fixation to ensure stable operation and meet the needs of different usage scenarios. The steel frame structure serves as both the supporting foundation for the display and a crucial guarantee for its normal operation.

[0003] Utility model patent CN210403035U discloses a mounting steel frame for an LED display screen, relating to the field of mounting steel frames, and aims to solve the problem of inconvenient installation of LED displays in existing technologies. The steel frame base plate has a slot, a connecting block is provided on one side of the upper end of the slot, a connecting rod is provided on one side of the connecting block, a fixing block is provided on one side of the lower end of the steel frame base plate, a support column is provided at the lower end of the fixing block, a stiffening plate is provided on the support column, a connecting seat is provided at the lower end of the stiffening plate, a steel frame side frame is provided on one side of the steel frame base plate, a connecting groove is provided inside the steel frame side frame, a support plate is provided inside the connecting groove, a fixing plate is provided on one side of the middle of the steel frame side frame, and a steel frame top frame is provided above the fixing plate.

[0004] While the existing technologies described above offer relatively convenient installation options for LED displays, their steel frame structures face severe environmental challenges when used outdoors. For example, in rainy weather or high-humidity environments, moisture in the air easily forms water droplets on the steel frame surface. Long-term accumulation leads to surface dampness, eventually causing corrosion and rust. This not only reduces the strength of the steel frame but may also affect the overall stability and safety of the display. Furthermore, moisture in humid environments may penetrate into the display's interior, jeopardizing the normal operation of electronic components. Therefore, addressing the shortcomings of traditional steel frame structures in terms of moisture-proofing and dehumidification performance, we propose a moisture-proof and dehumidifying steel frame structure for display screens to effectively cope with the impact of harsh environments on the steel frame, improving its service life and reliability.
