[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0034] A double-sided circular LED display screen includes a mounting box 1. The mounting box 1 has an internal receiving groove 16. Two symmetrically distributed support blocks 2 are fixedly connected to the inner wall of the receiving groove 16. A mounting block 3 is fixedly connected to the inner wall of the side of the two support blocks 2 that are close to each other. Two symmetrically distributed first mounting holes 4 are opened on the surface of the mounting block 3. A PCB circuit board 5 is arranged between the two mounting blocks 3. Two second mounting holes 6 are symmetrically opened on both ends of the PCB circuit board 5. Fastening bolts 7 are connected inside the first mounting holes 4 and the second mounting holes 6.

[0035] The surface of the support block 2 is connected from the inside out to the color reflector 8, light guide plate 9, diffuser 10, light enhancement plate 11 and display panel 12 respectively. The interior of the mounting box 1 is movably connected to the outer peripheral wall of the color reflector 8, light guide plate 9 and diffuser 10. The outer peripheral wall of the mounting box 1 is movably connected to the positioning block 14. A disassembly groove 15 is provided on one side of the positioning block 14.

[0036] By installing the housing 1, support block 2, mounting block 3, first mounting hole 4, PCB circuit board 5, second mounting hole 6, fastening bolt 7, color reflector 8, light guide plate 9, diffuser 10, brightness enhancement plate 11, display panel 12, and receiving slot 16, the purpose of easy disassembly and installation is achieved, which facilitates maintenance and replacement work, avoids the cumbersome installation and disassembly work, and solves the problem of time-consuming and labor-intensive maintenance and replacement work, thereby improving the convenience of use. At the same time, the setting of positioning block 14 and disassembly groove 15 facilitates quick sealing and quick disassembly, further improving the convenience of maintenance and replacement work.

[0037] In this embodiment, the support blocks 2 are distributed in a ring shape, and the inner diameter of the support blocks 2 is greater than the length of the PCB circuit board 5, which makes it easier for the PCB circuit board 5 to pass through the support blocks 2 and complete the disassembly, thereby improving the efficiency of maintenance and replacement.

[0038] In this embodiment, the two mounting blocks 3 are staggered and located on the front surface of one end and the back surface of the other end of the PCB circuit board 5, respectively, which facilitates a more stable installation of the PCB circuit board 5.

[0039] In this embodiment, the PCB circuit board 5 is connected to the mounting block 3 by a number of fastening bolts 7, and there are four fastening bolts 7, which are symmetrically distributed in pairs, thereby improving the firmness of the PCB circuit board 5 after installation.

[0040] In this embodiment, the diameters of the reflector 8, the light guide plate 9, and the diffuser 10 are smaller than the diameter of the receiving groove 16, and the diameters of the reflector 8, the light guide plate 9, and the diffuser 10 are larger than the inner diameter of the support block 2, thereby facilitating the support of the reflector 8, the light guide plate 9, and the diffuser 10 by the support block 2.

[0041] In this embodiment, the LED tube 13 is arc-shaped, and four LED tubes 13 are distributed at equal angles along the axis of the mounting box 1, which facilitates the provision of uniform light source, ensures clear presentation of text, images and animations, and thus improves the display effect.

[0042] Furthermore, when the color reflector 8, light guide plate 9, diffuser 10, brightness enhancement plate 11, and display panel 12 are installed on the surface of the support block 2, their outer peripheral walls will have a gap with the inner wall of the mounting box 1. This gap is consistent with the size of the LED tube 13, which facilitates the locking and positioning of the LED tube 13 within the gap between the outer peripheral walls of the color reflector 8, light guide plate 9, diffuser 10, and brightness enhancement plate 11 and the inner wall of the mounting box 1.

[0043] In this embodiment, the positioning block 14 is arc-shaped, and four positioning blocks 14 are distributed at equal angles along the axis of the mounting box 1, which facilitates the installation and fixing of the display panel 12 and makes subsequent disassembly easier.

[0044] Furthermore, the inner wall of the circular structure formed by the four positioning blocks 14 fits into the outer peripheral wall of the mounting box 1, thereby completing the installation of the positioning blocks 14 through the mutual interlocking between the four arc-shaped positioning blocks 14, and then fixing the display panel 12 with the positioning blocks 14.

[0045] In use, the double-sided circular LED display screen of this embodiment is first disassembled by inserting an external tool into the disassembly groove 15 and then prying the positioning block 14 through the disassembly groove 15 to facilitate the disassembly of the positioning block 14. This releases the positioning of the display panel 12. Then, the display panel 12, the brightness enhancement film 11, the diffuser film 10, the light guide plate 9, the color reflector 8, and the LED tube 13 are taken out in sequence. Next, the fastening bolts 7 are loosened and the PCB circuit board 5 is rotated to be misaligned with the mounting block 3, so that the PCB circuit board 5 can be taken out. This improves the disassembly efficiency and ensures the convenience of maintenance and replacement work.

[0046] After maintenance and replacement are completed, firstly, the PCB circuit board 5 is reinstalled between the two support blocks 2, and the PCB circuit board 5 is rotated to align with the two mounting blocks 3, so that the first mounting hole 4 and the second mounting hole 6 are aligned. Then, the PCB circuit board 5 is tightened with the fastening bolts 7. Next, the LED tube 13, the color reflector 8, the light guide plate 9, the diffuser 10, the brightness enhancement plate 11, and the display panel 12 are installed into the interior of the mounting box 1 in sequence, and the four positioning blocks 14 are fitted onto the outer peripheral wall of the mounting box 1. The positioning of the display panel 12 is achieved through the interlocking structure between the four positioning blocks 14, thereby improving the convenience of the installation work.
