Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Example, refer to Figures 1 - 5, a modular assembled LED display screen, including a fixing frame 1, a display screen 11 and an adjusting frame 15 arranged on the fixing frame 1. A plurality of support plates 2 are installed on the fixing frame 1. A plurality of installation grooves 3 are opened on one side of the support plate 2. A slot 4 is opened on the inner wall of the installation groove 3, and an adjusting groove 5 is opened on one side of the slot 4;

[0028] Four mounting blocks 12 inserted into the inner wall of the installation groove 3 are fixedly connected to the outer wall of the display screen 11 near the four corners. A magnet 13 is installed on one side of the mounting block 12;

[0029] Four fixing rods 16 respectively slidably connected to the inner wall of the adjusting groove 5 are installed on the outer wall of the adjusting frame 15. An iron block 17 is installed at one end of the fixing rod 16, and an adjusting spring 18 is sleeved on the outside of the fixing rod 16.

[0030] Furthermore; the mounting blocks 12 on the outside of the display screen 11 correspond to the installation grooves 3 on the support plate 2 one by one. One end of the fixing rod 16 is fixedly connected to the outer wall of one end of the iron block 17. The two side walls of the two ends of the adjusting spring 18 are respectively fixedly connected to one end of the iron block 17 and one inner wall of the adjusting groove 5. The magnet 13 and the iron block 17 are magnetically connected against the adjusting spring 18, and the iron block 17 is in a contracted state under normal conditions of the adjusting spring 18.

[0031] It should be noted that: when installing the display screen 11, the display screen 11 is inserted by aligning the mounting block 12 with the installation groove 3 on the support plate 2. At the same time, the magnet 13 enters the slot 4. At this time, the iron block 17 in the adjusting groove 5 is attracted by the magnet 13 to stretch the adjusting spring 18 and slide until the iron block 17 and the magnet 13 are firmly adsorbed together. At this time, the display screen 11 is fixed on the support plate 2 to complete the fixation. Through the cooperation of the magnet 13 and the iron block 17, the disassembly and assembly of the display screen 11 can be quickly realized, improving the installation efficiency. At the same time, when a single display screen 11 is damaged, it can be disassembled and replaced separately, reducing the cost expenditure.

[0032] Furthermore; buffer grooves 6 are opened on the two inner walls of the adjusting groove 5. A first piston chamber 7 is opened at one end of the buffer groove 6. An air passage 8 is opened at one end of the first piston chamber 7. A first piston rod 19 is piston-connected to the inner wall of the first piston chamber 7. A buffer block 20 slidably connected to the inner wall of the buffer groove 6 is installed at one end of the first piston rod 19. The buffer block 20 is a cone with a rounded end. One end of the buffer block 20 abuts against one side of the iron block 17. A second piston chamber 9 is opened at one end of the air passage 8. A receiving groove 10 is opened at one end of the second piston chamber 9. A second piston rod 21 is piston-connected to the inner wall of the second piston chamber 9. A return spring 22 fixedly connected to the inner wall of the second piston chamber 9 is installed at one end of the second piston rod 21. Positioning grooves 14 are opened on the two outer walls of the mounting block 12. A positioning block 23 inserted into the positioning groove 14 is installed at one end of the second piston rod 21.

[0033] It should be noted that during the process of the magnet 13 adsorbing the iron block 17 to fix the display screen 11, during the sliding process of the iron block 17, the side wall squeezes the buffer block 20 to move it into the interior of the buffer groove 6. At the same time, the second piston rod 21 at one end of the buffer block 20 compresses the space in the second piston chamber 9, causing air to flow through the air passage 8 to squeeze the first piston rod 19 in the first piston chamber 7. The first piston rod 19 compresses the return spring 22, causing the positioning block 23 at one end to disengage from the storage groove 10 and enter the positioning groove 14 on the side wall of the mounting block 12, thereby clamping and limiting the mounting block 12, further fixing the position of the mounting block 12, and strengthening the installation strength of the display screen 11.

[0034] The working principle of this modular assembled LED display screen:

[0035] When installing the display screen 11, the display screen 11 is inserted by aligning the mounting block 12 with the mounting groove 3 on the support plate 2. At the same time, the magnet 13 enters the slot 4. At this time, the iron block 17 in the adjustment groove 5 is attracted by the magnet 13 and slides by stretching the adjustment spring 18. The side wall of the iron block 17 squeezes the buffer block 20 to move it into the interior of the buffer groove 6. At the same time, the second piston rod 21 at one end of the buffer block 20 compresses the space in the second piston chamber 9, causing air to flow through the air passage 8 to squeeze the first piston rod 19 in the first piston chamber 7. The first piston rod 19 compresses the return spring 22, causing the positioning block 23 at one end to disengage from the storage groove 10 and enter the positioning groove 14 on the side wall of the mounting block 12. At the same time, the iron block 17 and the magnet 13 are firmly adsorbed together. At this time, the display screen 11 is fixed on the support plate 2 to complete the fixation. Through the fixation between the magnet 13 and the iron block 17 and the limitation of the mounting block 12 by the positioning block 23, the installation strength of the entire display screen 11 is improved. At the same time, when disassembling, only need to pull the adjustment frame 15 outward, so that the iron block 17 compresses the adjustment spring 18 and the magnet 13 is disengaged, and the display screen 11 can be quickly disassembled. This structure can quickly realize the disassembly and assembly of the display screen 11, improve the installation efficiency, and at the same time, when a single display screen 11 is damaged, it can be disassembled and replaced separately, reducing the cost expenditure.

[0036] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
