Moreover, through the latches 213 and the first protrusions 122, it is possible to make the installation and disassembly of the control box 2 extremely simple and quick, and the operation can be completed without complex tools or professional skills, which greatly shortens the installation and maintenance time, reduces labor costs, and improves work efficiency.

[0042] Furthermore, multiple protective members 4 are included. The multiple protective members 4 are correspondingly installed at the four corners of the frame 11 and the display module 3. The multiple protective members 4 cover the right-angle ends of the frame 11 and the display module 3, which can effectively absorb the impact force generated by external collisions or friction, reduce damage to the right-angle edges, protect the display screen from physical damage caused by accidental impacts, and extend the service life of the display screen.

[0043] Furthermore, the box body 1 also includes a plurality of snap-in plates 13. The plurality of snap-in plates 13 are respectively installed between the frame body 11 and the mounting plate 12, and the plurality of snap-in plates 13 are perpendicular to the mounting plate 12. The two ends of the plurality of snap-in plates 13 are respectively connected to the inner wall of the frame body 11 and the side wall of the mounting plate 12 to form a plurality of mounting positions in a rectangular array, which can enhance the rigidity of the frame body 11, especially in the installation area of ​​the display module 3, forming a stable support frame, effectively dispersing the weight and external force of the display module 3, and improving the stability and anti-deformation ability of the overall structure. The display module 3 is provided with a plurality of display modules 3, and the plurality of display modules 3 are detachably installed in a one-to-one correspondence on a plurality of mounting positions, which enables the display module 3 to be quickly and accurately positioned and fixed, simplifying the installation process.

[0044] Preferably, the display module 3 includes a bottom shell 31, a light board 32, and a plurality of rotary locks 33.

The positions of the plurality of second protrusions 5 correspond one-to-one to the positions of the plurality of rotary locks 33. The rotary locks 33 can rotate and can be engaged with the second protrusions 5. The bottom shell 31 is engaged with the mounting position through the engagement between the plurality of rotary locks 33 and the plurality of second protrusions 5. By providing the rotary locks 33 to engage with the second protrusions 5, it is possible to achieve quick engagement and release between the bottom shell 31 and the mounting position without the need for additional tools, thereby greatly improving the convenience of installation and maintenance. Furthermore, it ensures that the display module 3 is securely mounted within the housing 1, maintaining a good connection even in a vibrating or bumpy environment, thereby improving the structural stability of the entire display screen, while also reducing maintenance time and improving maintenance efficiency.
