[0031] By using the LED display device provided in this embodiment, the center beam box 20 is fixed to the connecting plate using the first fastener. When the LED display device set on the ceiling is repaired, it is only necessary to remove the LED display unit from the bottom of the LED display device, and then remove the first fastener from the bottom of the connecting plate 121, and the center beam box 20 can be removed, which facilitates maintenance operations on the LED display device suspended from the ceiling and improves maintenance efficiency.
[0032] It should be noted that the LED display device is arranged on the ceiling, and the side wall of the mounting beam 12 facing the enclosure 11 refers to the side wall of the mounting beam 12 located between the upper surface and the lower surface thereof.
[0033] like Figure 4 As shown, the LED display device further includes a flat cable 30, which is disposed on the rear side of the mounting beam 12, and is electrically connected to the LED display unit and the middle beam box 20. The flat cable 30 is used to electrically connect the LED display unit to the middle beam box 20, so as to realize both power supply to the LED display unit and signal transmission between the LED display unit and the middle beam box 20.
[0034] like Figure 1 As shown, the LED display device also includes a cable cover 40 and a plurality of second fasteners. The cable cover 40 extends along the extension direction of the cable 30. The cable cover 40 is arranged on the front side of the mounting beam 12, the front side of the middle beam box 20 and the front side of the cable 30. Each second fastener is passed through the cable cover 40 and is threadedly connected to the enclosure 11 or the mounting beam 12, so as to facilitate disassembly for after-sales maintenance.
[0035] like Figure 1 and Figure 4 As shown, there are multiple mounting beams 12, and the cable cover 40 includes a cover plate 41 and multiple positioning portions 42 arranged on the rear surface of the cover plate 41, each positioning portion 42 is arranged between two adjacent mounting beams 12 or between the mounting beam 12 and the enclosure 11, and the end of each positioning portion 42 abuts against the mounting beam 12 or the enclosure 11 in the extension direction of the cable 30, which can play a role in auxiliary positioning during installation.
[0036] like Figure 4 As shown, each positioning portion 42 includes two positioning protrusions 421, and the two positioning protrusions 421 are spaced apart in a direction perpendicular to the extension direction of the cable 30, and a routing channel for accommodating the cable 30 is formed between the two positioning protrusions 421, thereby facilitating the arrangement of the cable 30 and shielding the cable 30.
[0037] like Figure 1 and Figure 4 As shown, the LED display device further includes a connector 50, which is electrically connected to the flat cable 30 and the LED display unit. The connector 50 and the flat cable cover 40 are snap-fitted to facilitate disassembly for after-sales maintenance.
