[0040] Referring to Figures 1 to 3 The display screen box 100 provided by the embodiments of the present application can be assembled into a display device.

[0041] Referring to Figures 4 to 6 The display screen box 100 comprises a box frame 10, a display module 30 connected to the box frame 10, a power box 20 for supplying power to the display module 30 and connecting the box frame 10, and a magnetic attraction assembly 60.

[0042] The display module 30 and the power box 20 are respectively located on both sides of the box frame 10, thereby facilitating heat dissipation and maintenance. The power box 20 provides necessary power support for the display module 30, ensuring normal operation of the display module 30.

[0043] Referring to Figures 4 to 6The magnetic attraction assembly 60 comprises a first magnetic attraction piece 61 connected to the cabinet frame 10 and a second magnetic attraction piece arranged on the display module 30 and corresponding to the first magnetic attraction piece 61. The first magnetic attraction piece 61 and the second magnetic attraction piece are magnetically attracted to each other, so that the display module 30 is detachably connected to the cabinet frame 10. It can be understood that the first magnetic attraction piece 61 and the second magnetic attraction piece are arranged in pairs, and at least one of the first magnetic attraction piece 61 and the second magnetic attraction piece is a magnet. When the first magnetic attraction piece 61 is a magnet, the second magnetic attraction piece can be made of metal iron. Of course, the first magnetic attraction piece 61 and the second magnetic attraction piece can both be magnets. The magnet can be a permanent magnet, a constant magnet or a static magnet. In the embodiment, the first magnetic attraction piece 61 is a magnet and is connected to the cabinet frame 10. The second magnetic attraction piece is a metal iron sheet which is arranged in the display module 30 by a patch process. Thus, when the display module 30 is installed on the cabinet frame 10, the first magnetic attraction piece 61 and the second magnetic attraction piece are magnetically attracted to each other.

[0044] The display screen cabinet 100 provided by the embodiment of the present application can detachably fix the display module 30 to the cabinet frame 10 through the magnetic attraction assembly 60. The magnetic attraction effect between the first magnetic attraction piece 61 and the second magnetic attraction piece 62 can easily realize the connection of the display module 30 and the cabinet frame 10 and the separation of the display module 30 and the cabinet frame 10, thereby improving the convenience of dismounting or mounting the display module 30.
