When assembling the box body 1, the display area 11 away from the mounting area 12 (i.e., the display area 11 on the top side) is assembled first, and then the four display areas 11 close to the top side are assembled. The four front maintenance bottom shells 21 close to the top side abut the front maintenance bottom shell 21 on the top side, thereby preventing the front maintenance bottom shell 21 on the top side from sliding and loosening. By connecting the bottom plate 4 to the mounting area 12, the matching part 41 abuts the four front maintenance bottom shells 21 close to the top side, thereby preventing the four front maintenance bottom shells 21 close to the top side from shaking or loosening. This structure helps to maintain the stability of the whole during use, reduces loosening or instability caused by external vibration or movement, makes the overall assembly structure simpler and more reliable, reduces assembly time and workload, and realizes quick assembly.

[0054] Referring to Figure 5 The mounting area 12 is provided with mounting screw holes 13 which are distributed along the height direction of the box body 1. The bottom plate 4 is also provided with mounting bolts which are threadedly connected with the mounting screw holes 13. By passing the mounting bolts through the bottom shell and extending into the mounting screw holes 13, the bottom shell can be connected to the mounting area 12. In this embodiment, six mounting screw holes 13 are provided, which are distributed in two rows. Six mounting bolts are provided corresponding to the number of mounting screw holes 13. The six mounting bolts are threadedly connected with the six mounting screw holes 13 one by one, so that the bottom shell is more stable through the six mounting bolts and the six mounting screw holes 13.

[0055] The implementation principle of the present application is that when assembling the LED module 2, the plurality of studs 7 are inserted into the plurality of through holes 8 one by one to install the PCB board 22 on the front maintenance bottom shell 21, and the plurality of studs 7 are inserted into the plurality of through holes 9 one by one to install the face shield 24 on the front maintenance bottom shell 21. Finally, the module fixing bolt and the module fixing screw hole 10 are matched to fix the PCB board 22 and the face shield 24 on the front maintenance bottom shell 21.

[0056] When the LED module 2 is assembled on the display side of the box body 1, the front maintenance bottom shell 21 is driven to make the latch seat 31 extend into the slot 32 and the latch head 33 align with the latch hole 34. The front maintenance bottom shell 21 is moved along the length direction of the latch head 33 to make the latch head 33 extend into the latch hole 34, so that the front maintenance bottom shell 21 is assembled on the display area 11 of the box body 1. The assembly is simple, fast and stable.

[0057] When assembling the box body 1, the display area 11 away from the mounting area 12 (i.e., the display area 11 located on the top side) is assembled first, and then the display area 11 close to the assembled front maintenance bottom shell 21 around is assembled (i.e., the four display areas 11 close to the top side are assembled), the four front maintenance bottom shells 21 close to the top side are all abutted to the front maintenance bottom shell 21 on the top side, thereby preventing the front maintenance bottom shell 21 on the top side from sliding and loosening, and the bottom plate 4 is connected to the mounting area 12, so that the fitting part 41 is abutted to the four front maintenance bottom shells 21 close to the top side, thereby preventing the four front maintenance bottom shells 21 close to the top side from shaking or loosening, which helps to maintain the stability of the whole during use, reduces the loosening or instability caused by external force vibration or movement, makes the overall assembly structure more simple and reliable, and facilitates disassembly and assembly, reduces assembly time and workload, and realizes rapid assembly of the LED magic cube screen. Embodiment

[0058] The difference between the embodiment and the first embodiment is that Figure 8 In the embodiment, the display area 11 includes display units 14 that are closely distributed in an array, that is, the number of display units 14 in a single display area 11 is a perfect square. The number of LED modules 2 corresponds to the number of display units 14, and a plurality of LED modules 2 are installed one by one on a plurality of display units 14, so that the plurality of LED modules 2 in the display area 11 form a plane and abut each other.

[0059] In addition, the number of display units 14 of the five display areas 11 is consistent. Thus, different numbers of display units 14 can be used for splicing according to the required size of the LED magic cube screen.
