Compared with the existing technology, it can adjust the flatness of the LED display screen from multiple directions, resulting in a better display effect and solving the technical problem that the flatness of the existing LED display screen is not ideal.

[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0039] Example:

[0040] Reference Figure 1 and Figure 2 This embodiment 1 provides an XYZ three-axis adjustable LED display screen, including a display cabinet 1, a mounting back frame 2, and an adjustment component 3.

[0041] See Figure 2 and Figure 4 The mounting frame 2 is provided with mounting columns 22. One end of the mounting column 22 is connected to the mounting frame 2, and the other end is used to connect to the building wall or fixed frame, so that the mounting frame 2 is installed longitudinally on the building wall or fixed frame. The front of the mounting frame 2 is provided with a mounting groove 21 running through it in the longitudinal direction.

[0042] See Figures 7 to 9The adjustment assembly 3 is mounted on the display housing 1 and includes a T-nut 31, an adjusting screw 32, and an adjusting rubber ring 33. The T-nut 31 has a straight head 311 for engaging with the mounting groove 21. The adjusting rubber ring 33 is used for fine-tuning the distance between the display housing 1 and the mounting back frame 2. The display housing 1 has a waist-shaped adjusting through hole 11 for adjusting the position of the adjusting screw 32 left and right. The adjusting screw 32 extends from the waist-shaped adjusting through hole 11, passes through the adjusting rubber ring 33, and engages with the T-nut 31 threadedly, thus mounting the adjustment assembly 3 on the display housing 1. The adjustment assembly 3 also includes a washer 4, which is sleeved on the rod-shaped part 322, with one side abutting against the operating end 321 and the other side abutting against the end face of the waist-shaped adjusting through hole 11, thus covering and sealing the waist-shaped adjusting through hole 11.

[0043] When the display cabinet 1 is connected to the mounting frame 2 via the adjustment component 3, first fix the multiple mounting frames 2 in the preset positions on the wall, then install the adjustment component 3 at the four right angles of the display cabinet 1, then lift the display cabinet 1 so that the T-nut 31 rotates to be parallel to the mounting groove 21. Align it with the mounting groove 21 and insert it into the mounting groove 21. Then, turn the adjustment screw 32 forward to drive the T-nut 31's flat head 311 to rotate and lock it together with the mounting groove 21. At this time, the T-nut 31 and the mounting groove 21 are perpendicular to each other. Continue to turn the adjustment screw 32 forward to make the display cabinet 1 and the mounting frame 2 fit tightly together. First, adjust the vertical position of the display cabinet 1 on the mounting slot 21 to achieve adjustment of the display cabinet 1 in the Y-axis direction. Then, adjust the position of the adjusting screw 32 in the oblong adjusting through hole 11 to achieve adjustment of the display cabinet 1 in the X-axis direction. Finally, adjust the tightness of the engagement between the adjusting screw 32 and the T-nut 31, and combine this with the elasticity of the adjusting rubber ring 33 to change the degree of compression of the adjusting rubber ring 33, thereby adjusting the front-to-back flatness of the display cabinet 1 to achieve adjustment of the display cabinet 1 in the Z-axis direction. Finally, install the display module on the display cabinet 1. Compared with the existing technology, this method can adjust the flatness of the LED display screen from multiple directions, with a wider adjustment range and better display effect, solving the technical problem that the flatness of existing LED displays is not ideal.

[0044] See Figure 3In practical applications, the width of the straight head 311 is less than the width of the mounting groove 21, and the width of the mounting groove 21 is equal to the length of the straight head 311. Therefore, the straight head 311 can slide into the mounting groove. When the adjusting screw 32 is rotated, the straight head 311 can rotate 90 degrees in the mounting groove 21, thereby locking the straight head 311 in the mounting groove 21. After the straight head 311 is locked in the mounting groove 21, the adjusting screw 32 is rotated again, and the adjusting screw 32 moves relative to the straight head 311, so that the display cabinet 1 is locked onto the mounting back frame 2.

[0045] It should be pointed out that, such as Figure 9 As shown, both the left and right ends of the straight head 311 are curved surfaces.

[0046] See Figure 5 and Figure 6 As a feasible solution, the waist-shaped adjustment through hole 11 includes two semicircles and a rectangular segment located between the two semicircles. The rectangular segment is arranged horizontally to facilitate the adjustment of the position of the adjustment screw 32 in the waist-shaped adjustment through hole 11 in the horizontal direction, thereby changing the left and right position of the display cabinet 1.

[0047] See Figure 9 In some feasible solutions, the T-nut 31 includes a slotted head 311 and a screw mating part 312. The screw mating part 312 is a cylindrical structure protruding from the front of the slotted head 311 and is provided with an internal threaded through hole adapted to the adjusting screw 32. The internal threaded through hole penetrates the slotted head 311. The screw mating part 312 not only increases the travel of the display box 1 for front and rear adjustment, but also makes the connection surface between the adjusting screw 32 and the T-nut 31 larger, and the connection between the two is more stable and reliable.

[0048] See Figure 3 In actual use, the mounting back frame 2 is a profile component, and its length is set according to the actual situation. Four mounting slots 21 are arranged side-by-side on the front of the mounting back frame 2. Therefore, one display cabinet 1 can be connected horizontally on the same mounting back frame 2, or two adjacent display cabinets 1 can be connected. The two sides of each mounting slot 21 of the mounting back frame 2 bend towards each other and extend towards the bottom of the slot, forming a locking step 211. The locking step 211 is used to prevent the straight head 311 from sliding forward out of the mounting slot 21 when locked.

[0049] In actual production applications, the adjusting rubber ring 33 can be a silicone ring or other elastic rubber ring, which is placed between the display box 1 and the locking step 211 to serve as a buffer and adjust the distance between the two.

[0050] See Figure 9The adjusting screw 32 includes a rod-shaped portion 322 and an operating end 321. The diameter of the operating end 321 is larger than the diameter of the rod-shaped portion 322, and its end face is provided with an operating hole for mates with a tool. The rod-shaped portion 322 is threadedly connected to the screw mating portion 312. By turning the operating hole in the forward direction, the rod-shaped portion 322 moves in the internal threaded hole, thereby pressing the operating end 321 against the mounting frame 2, and fixing the display case 1 onto the mounting frame 2.
