The third fasteners 3132 include, but are not limited to, fastening bolts or fastening screws. The electrical mounting plate 31 is fixed by hanging, which improves its installation efficiency.

[0049] like Figure 10 As shown, in some embodiments, the electrical device 30 further includes an electrical cover 33, which includes an electrical cover body 331. The electrical cover body 331 may be provided with a plurality of ventilation holes to achieve ventilation.

[0050] The upper end of the appliance cover body 331 bends inward and upward to form a third mounting plate 332, and the upper end of the appliance cover body 331 bends inward and downward to form a fourth mounting plate 333. The third mounting plate 332 has several second gourd holes 3321 for easy attachment to the second fastener 3122 of the first transverse beam 45. These second gourd holes 3321 can be evenly distributed along the horizontal direction of the third mounting plate 332. The fourth mounting plate 333 has second locking holes 3331, and the third fastener 3132 passes through both the second locking holes 3331 and the first locking holes 3131 to connect with the second transverse beam 46. Here, "inward" refers to the direction towards the display 20.

[0051] like Figure 8 and Figure 9 As shown, in some embodiments, at least a portion of the electrical component 32 is provided with a limiting hole 321, and the electrical mounting plate 31 is provided with a plurality of limiting members 314.

A limiting portion 3142 is provided at the end of the plug-in portion 3141 away from the electrical mounting plate 31. The plug-in portion 3141 is used to pass through the limiting hole 321, and the limiting portion 3142 is used to deform under force to abut against the surface of the end of the electrical component 32 away from the electrical mounting plate 31. This achieves limiting and fixing of the electrical component 32, and enables rapid assembly and replacement of the electrical component 32. During on-site assembly, the amount of fastening bolts or screws used can be reduced, improving convenience.

[0052] In some embodiments, the electrical device 32 includes, but is not limited to, a power supply, a surge protector, a residual current device (RCD), and a speed control board. The surge protector and the RCD may be provided with limiting holes 321.

[0053] like Figure 6 As shown, in some embodiments, the cabinet 10 also includes several speakers 50, which are connected to the electrical device 30 via connectors. For example, the speaker 50's cable has a male connector, and the electrical device 30 includes a female connector, allowing for plug-in connection and fixation. Furthermore, as... Figure 6 As shown, an intermediate connector 60 is provided in the space between the speaker 50 and the electrical device 30 inside the cabinet 10. The cable of the speaker 50 may be provided with a male connector, which is connected to the intermediate connector 60, and the intermediate connector 60 is then connected to the electrical device 30.

[0054] The speaker 50 can be located at the lower part of the cabinet 10, and the electrical device 30 is located at the upper part of the cabinet 10, so that the internal space of the cabinet 10 is more rationally distributed.

[0055] In some embodiments, the number of speakers 50 is two, and the two speakers 50 are symmetrically arranged on the cabinet 10 near its bottom. Providing multiple speakers 50 can enhance the stereo effect of the advertising sound.

[0056] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
