[0042] As shown in Figures 1 to 7 In the vertical direction, the size of the second positioning slot 1119 is greater than the size of the second positioning protrusion 1118. In this way, taking the LED boxes spliced in the 2*2 mode as an example, when the left upper, left lower and right lower LED boxes are connected and the right upper LED box is to be spliced, the first positioning protrusion 1113 is first insertedly matched with the first positioning slot 1114, so as to complete the positioning of the right upper LED box and the right lower LED box. Since the size of the second positioning slot 1119 is greater than the size of the second positioning protrusion 1118, the second positioning protrusion 1118 of the right upper LED box can be smoothly inserted into the second positioning slot 1119 without interference when being inserted obliquely into the second positioning slot 1119 of the left upper LED box. After the positioning is completed, the adjacent LED boxes are fastened by using bolts.

Specifically, the first connecting piece 61 is a magnet, and the second connecting piece 62 is made of a magnetic material. The first connecting piece 61 and the second connecting piece 62 are magnetically attracted and matched. Since the front surface of the second connecting piece 62 is located at the rear side of the front surface of the mounting frame 10, when the first connecting piece 61 cooperates with the second connecting piece 62, the second connecting piece 62 will not cause the LED display module 20 to be unable to be attached to the front surface of the mounting frame 10 due to the lifting of the LED display module 20. Since the front surface of the second connecting piece 62 is located at the rear side of the front surface of the mounting frame 10 and is provided with a preset interval between the front surface of the mounting frame 10, and the preset interval is greater than or equal to the thickness of the first connecting piece 61, the LED display module 20 will not be unable to be attached to the front surface of the mounting frame 10 due to the first connecting piece 61 being too thick and the preset interval being too small. The first connecting piece 61 cooperates with the second connecting piece 62 to cause the rear surface of the flexible lamp panel 21 to be completely attached to the front surface of the mounting frame 10, thereby causing the flexible lamp panel 21 to deform to adapt to the preset installation curved surface, so that the single flexible lamp panel 21 has a suitable arc, and the display surface formed by the plurality of flexible lamp panels 21 has better smoothness. The staff can process the arc of the front surface of the mounting frame 10 according to the needs, so as to ensure that the arc of the display surface formed by the flexible lamp panel 21 meets the display needs.
