[0036] Such as Figures 1 to 9As shown in the figure, a structure for adjusting the flatness of assembled display screens includes a leveling connecting member 1. At least two display screen boxes 2 are connected by the leveling connecting member 1. Any two adjacent display screen boxes 2 are respectively a first box 21 and a second box 22.

[0037] A plurality of first adjusting columns 11 are provided on each leveling connecting member 1. The first adjusting columns 11 pass through the leveling connecting member 1 and are threadedly connected to the display screen box 2, so that when the first adjusting columns 11 are screwed inwards or outwards, the display screen box 2 is driven to move in the X-axis direction.

[0038] The structure for adjusting the flatness of assembled display screens in this solution is particularly suitable for the installation of LED display screens. The structure is simple, the operation is convenient, and the flatness of the LED display screen box 2 can be quickly and accurately adjusted.

[0039] Specifically, a leveling connecting member 1 is additionally provided on the display screen box 2. Since the leveling connecting member 1 is provided with first adjusting columns 11, after a plurality of LED display screen boxes 2 are assembled, when a certain box is misaligned or has a height difference, by adjusting the first adjusting columns 11 on the leveling connecting member 1, tightening or loosening the first adjusting columns 11 (which can be fastening screws), the display screen box 2 connected to the first adjusting columns 11 will rise or fall accordingly, realizing the fine adjustment of the display screen box 2, so that the adjacent display screen boxes 2 are on the same plane and maintain a high flatness. This structure allows on-site quick correction of the slight deviations between the boxes through the leveling connecting member 1 with a fine adjustment effect, ensuring that the overall surface of the assembled display screen is flat and consistent, and improving the visual effect and installation efficiency.

[0040] Furthermore, the leveling connecting member 1 is installed at any corner of the display screen box 2. Any four adjacent display screen boxes 2 are connected by one leveling connecting member 1, and at least one first adjusting column 11 is provided on each display screen box 2.

[0041] As Figure 1 and Figure 9 shown in the figure, each leveling connecting member 1 in this solution can connect at least two adjacent display screen cabinets 2. For example, 2, 3, or 4 display screen cabinets. Preferably, the outer contour of the leveling connecting member 1 in this solution is rectangular, and each leveling connecting member 1 simultaneously connects and fixes four display screen cabinets, and a corresponding first adjusting column 11 is provided on each display screen cabinet to adjust its front and rear positions.

[0042] Of course, in other embodiments, more first adjusting columns 11 can be provided in the area of the leveling connecting member 1 corresponding to each display screen cabinet and adjusted adaptively in different usage scenarios.

[0043] Further, it further includes a locking bolt 3, and any two adjacent display screen boxes 2 are connected by at least one of the locking bolts 3;

[0044] The locking bolt 3 includes a head 31, a connecting column 32 and a tail 33 connected in sequence. An external thread is provided on the outer periphery of the tail 33. The diameter of the connecting column 32 is < the diameter of the tail 33. A first connection hole 211 is provided on the first box body 21, and a second connection hole 221 is provided on the second box body 22. A threaded section 2111 is provided on the outer side of the inner wall of the first connection hole 211, and a smooth section 2112 is on the inner side. An internal thread is provided in the second connection hole 221. The locking bolt 3 passes through the first connection hole 211 and is threadedly connected in the second connection hole 221 to fix the first box body 21 and the second box body 22.

[0045] As Figures 5 to 7 shown, locking bolts 3 can be provided on the left and right sides and the upper and lower sides of the LED display screen box 2. The locking bolt 3 is actually a non-loosening screw. For example, a non-loosening screw is installed on the left side of the first box body 21. The structural design of the non-loosening screw is that half is a thread (i.e., the threaded section 2111 of the tail 33), and half is a cylindrical connecting column 32. The diameter of the connecting column 32 is smaller than the diameter of the connection hole. The inner wall of the first connection hole 211 of the first box body 21 where the non-loosening screw is installed is half thread near the outside, and the inner diameter of the first connection hole 211 near the inside is larger than the diameter of the non-loosening screw, forming a structure where the screw does not come out. A second connection hole 221 with a full thread corresponding to the first connection hole 211 (locking bolt 3) is provided on the right side of the second box body 22. When adjusting the gap between two adjacent display screen boxes 2 during assembly, through the connection of the non-loosening screw, the two display screen boxes 2 can be closely and seamlessly connected, solving the problem of the gap between the boxes. At the same time, the flatness of the display screen box 2 in the Y-axis and Z-axis directions can be further adjusted by adjusting the tightness of the locking bolt 3.

[0046] One locking bolt 3 can be provided on the side of the display screen box 2 in this solution. Of course, in order to ensure a better locking and fixing effect between the display screen boxes 2, in other embodiments, more connection holes can also be opened. For example, two display screen boxes 2 can be fixed by two, three or more locking bolts 3, and adjusted according to different scene adaptabilities.

[0047] Furthermore, the leveling connector 1 is located on the front side of the display screen box body 2, and an installation bracket 4 is also provided on the rear side of the display screen box body 2. The second adjustment column 42 sequentially passes through the leveling connector 1, the display screen box body 2, and the installation bracket 4, and the end of the second adjustment column 42 is threadedly connected to the connecting piece, so that when the second adjustment column is screwed inwards or outwards, the display screen box body 2 is driven to move on the X-axis.

[0048] As Figure 4 shown, the leveling connector 1 is located on the front side of the display screen box body 2 and can usually be installed at the four-corner groove positions of the box body. The installation bracket 4 is installed on the back of the display screen box body 2 and is mainly used to fix the display screen box body 2. The display screen box body 2 of the LED display screen is also provided with a hole position for the second adjustment column 42 to pass through on the installation groove 23. The second adjustment column is used to connect the connecting piece 41 of the two holes. Two corresponding installation tooth holes are provided on the connecting piece 41 of the two holes. After the display screen box body 2 of the LED display screen is installed on the installation bracket 4 of the steel structure, the long strip-shaped second adjustment column (which can be a locking bolt) passes through the leveling connection piece 1, the display screen box body 2, and the installation bracket 4, and is finally threadedly fixed at the tooth hole of the connecting piece 41, so that the display screen box body 2 can be closely attached to the installation bracket 4 (which can be a square tube of the steel structure during installation), that is, the position of the display screen box body 2 in the X-axis direction can be further adjusted.

[0049] In summary, through the setting of the leveling connector 1, the first adjustment column 11, the locking bolt 3, the connecting piece, and the second adjustment column, the fine adjustment of the LED display screen box body 2 in the three directions of the X, Y, and Z axes during assembly is realized, so that the entire display screen surface is flat and consistent, improving the visual effect and installation efficiency.

[0050] Furthermore, the display screen box body 2 is provided with an installation groove 23 for installing the leveling connector 1. The installation groove 23 is provided with a limiting portion 231. There is a limiting gap 232 between the end of the limiting portion 231 and the inner wall of the installation groove 23. A through hole 12 is opened in the middle of the leveling connector 1. The limiting portion 231 is clamped in the through hole 12, and the leveling connector 1 is clamped in the limiting gap 232.

[0051] At the corners or other positions of the LED display cabinet 2, installation grooves 23 corresponding to the leveling connectors 1 can be provided. An installation space is provided in the installation grooves 23 so that the leveling connectors 1 can be placed in the installation grooves 23. To ensure that the installation grooves 23 do not shift, a plurality of fixing threaded holes for connecting the first adjusting columns 11 are provided in the installation grooves 23. A limiting portion 231 is also provided in the installation grooves 23. In the front projection plane, the limiting portion 231 of this solution can be in a cross shape. There is a limiting gap 232 between the four sides of the cross-shaped limiting portion 231 and the inner wall of the installation groove 23. During installation, the cross-shaped limiting portion 231 is stuck in the through holes 12 of the leveling connectors 1, and at the same time, the leveling connectors 1 are stuck in the limiting gaps 232, realizing the quick installation of the leveling connectors 1.

[0052] In this solution, the end faces of the installation grooves 23 are machined with chamfers, and at the same time, the leveling connectors 1 are also machined with chamfers to reduce assembly errors.

[0053] Furthermore, a plurality of positioning columns 233 are provided in the installation grooves 23, and a plurality of positioning holes 13 corresponding to the positioning columns 233 are provided on the leveling connectors 1. The positioning columns 233 are inserted into the positioning holes 13. A plurality of protruding positioning columns 233 are also provided in the installation grooves 23. Correspondingly, a plurality of positioning holes 13 are provided on the leveling connectors 1 as described above. The positioning columns 233 are inserted into the positioning holes 13, enabling the leveling connectors 1 to be quickly positioned before the bolts are tightened and not easily shifted.

[0054] Furthermore, a plurality of horizontal detection components 5 installed on the display cabinet 2 are included. The horizontal detection components 5 are used to detect whether the display cabinet 2 is in a horizontal state. In this embodiment, the horizontal detection components 5 can be installed on each display cabinet 2 or several of the display cabinets 2. Specifically, it can be a level. The level can be installed in the left-right direction and the up-down direction of the display cabinet 2, and can provide real-time feedback on whether the display cabinet 2 is horizontally installed. When there is a deviation in the assembly of the LED display cabinet 2, the adjustment direction can be quickly found through the level.

[0055] Furthermore, a plurality of fixing pins 213 are provided on at least one side edge of the first cabinet 21, and a plurality of fixing holes 222 corresponding to the fixing pins 213 are provided on the second cabinet 22. The fixing pins 213 are inserted into the fixing holes 222.

[0056] Similar to the traditional LED display cabinet 2, positioning columns 233 and positioning holes 13 can also be provided on the side edges of the LED display cabinet 2 of this solution. Among two adjacent LED display cabinets 2, a plurality of positioning holes 13 can be provided on the top edge of the first cabinet 21 (the second cabinet 22), and fixing pins 213 can be provided on the bottom edge. In this way, quick positioning and assembly can be achieved when the two cabinets are assembled.
