The box body 1 includes at least one display screen frame 11 for installing the display screen module 2. The display screen frame 11 includes a maintenance hole 111 and multiple first installation objects 112. The maintenance hole 111 passes through the display screen frame 11, and the first installation objects 112 surround the maintenance hole 111; the back of the display screen module 2 is provided with a holding structure and multiple second installation objects 23, the positions of the second installation objects 23 correspond to the positions of the first installation objects 112, and the second installation objects 23 are used to be correspondingly installed on the first installation objects 112 to form a pluggable structure, and the pluggable structure includes a magnetic structure; the holding structure is located in the middle of the display screen module 2, and when the second installation object 23 is installed on the first installation object 112, the holding structure is located in the maintenance hole 111.

[0040] Alternatively, as Figure 1 As shown, a plurality of display screen modules 2 can be arranged on the display screen frame 11 , and the sizes and structures of the plurality of display screen modules 2 can be the same or different.

[0041] Alternatively, as Figure 2 、 Figure 3 As shown, first mounting object 112 includes a first column and a first fixing member 1121. The bottom end of the first column is fixed to display screen frame 11, and the top end extends toward the mounting side of display screen frame 11. First fixing member 1121 is fixed to the top end of the first column. Second mounting object 23 includes a first column, the top end of which extends to form a boss corresponding to the top of first fixing member 1121. Display screen module 2 is provided with a mounting hole 24 for accommodating the first column. To facilitate removal and installation of display screen module 2, the dimensions of mounting hole 24 correspond to the dimensions and structure of the first column and boss, and the inner wall of mounting hole 24 does not have any structure (such as lack of threads) that would hinder the quick removal or installation of the first column and boss.

[0042] Optionally, the first column can be arranged on the back of the display screen module 2 and away from the middle area of the back. To facilitate installation, the first installation object 112 can be correspondingly arranged on the display screen frame 11.

[0043] In one embodiment, to facilitate quick installation and fixation, first fixing member 1121 is made of a magnetic material. The boss at the top of the first column is attracted to first fixing member 1121. The material constituting the first column includes at least one of iron, nickel, and cobalt. The first column is attracted to first fixing member 1121. Because first installation object 112 and second installation object 23 are fixed by adsorption, when removing display module 2, a suction cup tool can be used to absorb the front surface of display module 2 and then remove display module 2 from display frame 11.

[0044] Alternatively, as Figure 4 As shown, the holding structure includes a handle 22 and a base 21. The base 21 is fixed to the back of the display module 2, and the handle 22 is fixed to the side of the base 21 away from the back of the display module 2. The handle 22 can be used to push the display module 2 from the back of the display frame 11 to separate the display module 2 from the display frame 11.

[0045] Optionally, the base 21 includes a first branch and a second branch arranged crosswise, forming an X-shaped base 21. The base 21 enhances the strength of the back of the display module 2. Furthermore, signal transmission pathways and power transmission pathways connected to the display module 2 may be provided in the first and second branches, and a signal transmission interface 331 and a power transmission interface may be provided on the first or second branch, respectively.

[0046] Optionally, the second installation object 23 may be partially or entirely provided on the first branch or the second branch.

[0047] Optionally, the handle 22 includes a gripping rod, a vertical rod, a pin, and a base plate. The base plate is fixed to the base bracket 21. The side of the base plate away from the base bracket 21 is raised to form a fixed column. The middle portion of the gripping rod is fixed to one end of the vertical rod. The end of the vertical rod away from the gripping rod has an opening, and the fixed column is embedded in the opening. The pin extends through the fixed column and the side wall of the opening. The action of the pin allows the vertical rod to rotate relative to the fixed column, thereby reducing the space occupied by the handle 22.

[0048] In one embodiment, Figure 4 As shown, the ends of the gripping rods are curved for easier gripping, and the length of the gripping rods and the width of the vertical rods are designed to accommodate the hand structure of maintenance personnel. The ends of the base plate can be screwed to the base bracket 21. To remove the display module 2 for post-maintenance, firmly push forward with the handle 22 to separate the first mounting object 112 from the second mounting object 23. The display module 2 can then be rotated to a 45° diagonal position relative to the area where it is located. The display module 2 can then be removed for maintenance.

[0049] Optionally, the display screen modules 2 installed in the housing 1 have the same shape. The housing 1 includes spaced-apart horizontal panels 113 and spaced-apart vertical panels 114. The horizontal panels 113 and vertical panels 114 intersect perpendicularly to form multiple display screen frames 11. Each display screen frame 11 is correspondingly mounted with one or more display screen modules 2. The display screen structure also includes a mounting base 31. The middle portion of the mounting base 31 is fixed to the vertical panels 114 between adjacent display screen frames 11, located on the side of the vertical panels 114 away from the display screen modules 2, and the two ends of the mounting base 31 are connected to different vertical panels 114. The components for controlling the display screen modules 2 are mounted via the mounting base 31.

[0050] Alternatively, as Figure 5 As shown, the mounting base 31 can also be used to fix the display screen module 2. The display screen structure also includes a control box. The first mounting object 112 is provided on the side of the mounting base 31 facing the display screen module 2; the mounting base 31 is provided with a mounting groove on the side away from the display screen module 2. The shape of the mounting groove corresponds to the shape of the control box, and a plurality of positioning columns 311 are provided in the mounting groove. A positioning hole 322 corresponding to the positioning column 311 is formed on the side of the control box facing the mounting groove. The positioning column 311 is used to be inserted into the positioning hole 322 to fix the control box, and the control box is fixed to the mounting base 31 through the positioning column 311.

[0051] Optionally, the positioning column 311 may be provided with a magnet or a material that can be absorbed by a magnet, and the positioning hole 322 may be correspondingly provided with a material or magnet that can be absorbed by a magnet, thereby utilizing the absorption function of the magnet to achieve rapid positioning and fixation of the control box and the mounting base 31.

[0052] Alternatively, as Figure 10 As shown, the control box includes a control unit and a rear cover 32. Positioning holes 322 are located on the side of the rear cover 32 facing the mounting slot. Positioning holes 322 correspond one-to-one with positioning posts 311. The rear cover 32 snaps into the mounting slot to form a space for accommodating the control unit. The width of the maintenance hole 111 is greater than that of the rear cover 32, making it easier to remove the rear cover 32 and the components inside it from the maintenance hole 111 during front maintenance.

[0053] In one embodiment, the control unit and the display screen module 2 are formed in a modular design, and different display screen modules 2 have the same structure and can receive control instructions from the same control unit. Figure 9 As shown, the control unit includes a power module 333 connected to each display module 2 on the display frame 11, a power supply interface 332, a signal transmission interface 331, a receiving card 335 module, and a signal adapter module 334. The signal adapter module 334 is installed on the side of the power module 333 facing the mounting base 31, and the receiving card 335 is located on the side of the signal adapter module 334 facing away from the power module 333. The power supply interface 332 and the signal transmission interface 331 are fixed to the side wall of the rear cover 32, located on the side of the power module 333. Among them, the receiving card 335 is plugged into the signal adapter module 334.

[0054] Alternatively, as Figure 6 、 Figure 7 As shown, in order to facilitate the quick removal of the back cover 32 of the control box, the control box also includes a locking mechanism 321. The locking mechanism 321 is rotatably fixed to both ends of the back cover 32. The fixed end of the locking mechanism 321 is movably fixed to the mounting base 31. The fixed state of the fixed end corresponds to the rotation state of the locking mechanism 321.

[0055] Optionally, a first boss 312 and a second boss 313 are provided at both ends of the mounting base 31. The fixed end of the locking mechanism 321 is movably fixed to the first boss 312 and abuts against the second boss 313. The second boss 313 provides a reaction force to lift the rear cover 32 of the control box. The first boss 312 and the second boss 313 extend away from the rear cover 32.

[0056] In one embodiment, Figure 8 As shown, each end of the rear cover 32 is provided with a locking mechanism 321. This locking mechanism 321 includes a locking member 3211, a locking hook 3213, and a rotating shaft 3212. Axial holes are provided on both ends of the locking member 3211 and the locking hook 3213. The rotating shaft 3212 inserts into these holes, and the locking hook 3213 is rotatably fixed to the ends of the locking member 3211 via the rotating shaft 3212. The locking member 3211 has protrusions on both ends of the side near the rear housing. These protrusions insert into the rear cover 32 to attach the locking mechanism 321 to the rear cover 32. The position where these protrusions are inserted into the rear cover 32 corresponds to the position of the first protrusion 312. When the locking member 3211 moves toward the rear cover 32, the locking hook 3213 hooks onto the first protrusion 312, thereby securing the rear cover 32 to the mounting base 31. When the locking member 3211 moves away from the rear cover 32, the locking hook 3213 disengages from the first boss 312, and the ends of the locking member 3211 abut against the second boss 313. The second boss 313 provides a reaction force to lift the rear cover 32, thereby achieving the separation of the rear cover 32 from the mounting base 31.
