The power supply box 20b is fixedly connected. The fixing member 40 may be a screw or a combination of bolts and nuts. The first power supply box 20a and the second power supply box 20b are fixed by the fixing member 40. When the power supply box 20 and the frame 110 are integrally formed, the power supply boxes 20 are fixed to each other to realize the first box body 10a and the second box body 10b fixation, no additional splicing structure is required. The method of fixing the box body 10 by the fixing member 40 also reduces the cost compared with the method of fixing the box body 10 by a splicing lock.

In one or more embodiments, the box bodies 21 of the first power supply box 20a and the second power supply box 20b are provided with a plurality of second bosses 23 on side walls close to each other, and the first perforation 202 may be provided in the second On the boss 23. By arranging the first perforation 202 on the second boss 23, the side wall of the power supply box 20 is thickened at the corresponding position of the first perforation 202 to avoid the deformation of the power supply box 20.

When the first power supply box 20a is arranged on the edge of the first frame 110a, the fixing member 40 can be used to fix the different frames 110, and then cooperate with the first through hole 21a on the box body 21 and use the connecting pipe 30 to connect the different boxes 10 The internal cavity 201 in the power supply box 20 is connected, so that two different boxes can be introduced through the same external power line and signal line, and then the internal cables are passed through the connecting tube 30 to realize the electronic components in the two power supply boxes 20 Electrical connection and signal connection. In this way, two boxes 10 form a box group for splicing, which can save the cost of splicing components between the two boxes 10, and in addition, can save the cables and wires used by the power box 20 The number of cable connectors can greatly reduce the cost of cable layout. At the same time, the connection cables between the two boxes 10 are routed internally, which also improves the waterproof performance.

In one or more embodiments, along the thickness direction of the first box 10a, at least one first perforation 202 and the remaining first perforations 202 are arranged in a staggered manner, rather than on the same horizontal straight line. For example, two adjacent first perforations 202 can be arranged in a staggered manner, so that when the fixing member 40 is used for fixing, the three adjacent fixing members 40 can be formed into a triangular structure, which enhances the strength of the connection and avoids shaking back and forth. Conducive to the adjustment of flatness during splicing. It can be understood that a waterproof ring may be provided between the fixing member 40 and the periphery of the first through hole 202 to achieve waterproofing at the first through hole 202.

In one or more embodiments, the side of the box body 21 close to the mounting portion 111 can be hollowed out, and the LED display module 130 directly seals the side of the box body 21 close to the mounting portion 111, so that the power box 20 Can realize easy maintenance before realization.
