It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a mini LED scrolling display screen. Figure 1-4 As shown, it includes a mounting frame 1 and a docking plate 2, the mounting frame 1 is located on one side of the docking plate 2, a mini LED lamp bead 3 is embedded in the central position of the outer wall of one side of the docking plate 2, a pin 4 is arranged on the outer wall of one side of the mini LED lamp bead 3, a pin hole 5 and a limiting groove 6 are opened on the outer wall of one side of the mounting frame 1, the pin 4 and the pin hole 5 match and fit, the pin hole 5 is located on one side of the limiting groove 6, a mounting block 7 is integrally formed on the outer wall of one side of the mounting frame 1, a total of four mounting blocks 7 are arranged, and the four mounting blocks 7 are symmetrically arranged on the outer wall of one side of the mounting frame 1, and the outer wall of one side of the docking plate 2 is close to the side of the mini LED lamp bead 3 A through slot 10 is provided at the position, and there are two through slots 10 in total, and the two through slots 10 are symmetrically provided on the outer wall of the docking plate 2, a moving block 8 is provided inside the through slot 10, and a slider 9 is integrally formed on one outer wall of the moving block 8, a sliding slot 11 is provided on one inner wall of the through slot 10, a spring 12 is provided between the outer wall of the moving block 8 and the inner wall of the through slot 10, a round rod 13 is integrally formed at the central position of the outer wall of one side of the moving block 8 adjacent to the slider 9, and an insertion rod 14 is integrally formed at the central position of the outer wall of the moving block 8 on the side away from the round rod 13, and the length of the insertion rod 14 is the same as the sum of the widths of the docking plate 2 and the mounting frame 1.

[0023] A limiting block 15 is integrally formed at one end of the insertion rod 14 .

[0024] It should be noted that, due to the unreasonable design of the conductive connection structure of the existing mini LED display screen, there are problems such as easy disconnection during connection and unstable and loose connection. When individual LED modules fail, the lamp beads need to be removed and replaced. The staff may easily touch the nearby lamp beads during disassembly, which may cause large-scale damage. In this embodiment, a part of the limit block 15 is attached to the outer wall of one side of the mounting frame 1 to provide a limit surface for the docking of the docking plate 2 and the mounting frame 1, thereby ensuring that the mounting frame 1 and the docking plate 2 are firmly and stably connected, so that the pin 4 can be accurately inserted into the pin hole 5, ensuring sufficient contact and improving the stability and firmness of the connection. The mini LED lamp bead 3 can be disassembled by bringing the two round rods 13 on the outer side of the mini LED lamp bead 3 together and then pulling them out. The disassembly operation is simple and it is not easy to touch the nearby lamp beads. The mini LED lamp bead 3 can be disassembled with only the index finger and thumb.

[0025] Specifically, in this embodiment, the scheme mainly includes a mounting frame 1 and a docking plate 2. When in use, the mounting frame 1 is fixedly installed at the required position of the display screen. When the mini LED lamp beads 3 are installed, the pins 4 on the mini LED lamp beads 3 are inserted into the pin holes 5 on the mounting frame 1. During the docking process between the docking plate 2 and the mounting frame 1, the limit block 15 contacts the limit groove 6. After the limit block 15 is squeezed, the slider 9 slides in the slide groove 11, so that the moving block 8 slides in the through groove 10. After the spring 12 is compressed, the limit block 15 can smoothly pass through the limit groove 6. When the squeezing force on the limit block 15 disappears, the spring 12 is reset by its own resilience, and the spring 12 pushes the moving block 8 to move. The insertion rod 14 and the limit block 15 on the moving block 8 move synchronously, and a part of the limit block 15 moves to one side of the limit groove 6 to limit the position of the limit block 15, thereby realizing the docking of the docking plate 2 and the mounting frame 1, and ensuring the stability and firmness of the docking. When the mini LED lamp bead 3 needs to be removed, the operator presses the thumb and index finger on the round rod 13 on both sides of the mini LED lamp bead 3 respectively, and brings the two round rods 13 closer, and the moving block 8 slides in the through groove 10, so that the limit block 15 moves to one side of the through groove 10, and then the mini LED lamp bead 3 is pulled outward, so that the docking plate 2 and the mounting frame 1 are separated, and then the docking plate 2 is disassembled. The disassembly is simple, and the mini LED lamp bead 3 can be disassembled with only the index finger and thumb.

[0026] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the slider 9 and the slide groove 11 are slidably connected, and the cross sections of the slider 9 and the slide groove 11 are both T-shaped structures.

[0027] In this embodiment, the sliding block 9 and the sliding groove 11 of the T-shaped structure can ensure the stability of the movement of the moving block 8 in the through groove 10.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the cross section of the limiting block 15 is a right-angled triangle structure.

[0029] In this embodiment, the limiting block 15 with a right-angled triangle structure can provide a limiting surface for the connection between the docking plate 2 and the mounting frame 1, thereby preventing the docking plate 2 from falling off the mounting frame 1.

[0030] In a further preferred embodiment of the present invention, Figure 1 As shown, the insertion rod 14 passes through the limiting groove 6 , and the length of the insertion rod 14 is equal to the sum of the widths of the docking plate 2 and the mounting frame 1 .

[0031] In this embodiment, the insertion rod 14 can fully penetrate the docking plate 2 and the mounting frame 1 , and the limiting block 15 at one end of the insertion rod 14 can be attached to an outer wall of one side of the mounting frame 1 .
