Technical Field

[0001] This utility model belongs to the field of LED splicing screen technology, specifically, it relates to a magnetic module for LED splicing screens. Background Technology

[0002] An LED video wall is a large-screen display device composed of multiple LED (light-emitting diode) display units. Each display unit of an LED video wall contains a large number of LED beads. These LED beads emit light under the drive of electrical signals. By controlling the on / off state of each bead and the color combination, various text, images, and videos can be displayed. For example, in a full-color LED display unit, red, green, and blue LED beads emit light in a certain proportion and mix to produce a variety of color effects.

[0003] However, existing LED splicing screens still have certain drawbacks. For example, they are extremely troublesome to install, requiring each LED splicing screen module to be fixed and installed one by one, mostly using bolt fixing methods. At the same time, each module of the LED splicing screen also needs to be connected to the circuit, which is time-consuming and labor-intensive. Furthermore, disassembly is also cumbersome during maintenance and replacement, increasing the workload, reducing work efficiency, and delaying the use of the LED splicing screen. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 8 As shown, the magnetic module of the LED splicing screen includes a mounting bracket 1, an LED bead board 13, and a suction cup housing 9. A back plate 7 is fixedly connected to the inner side of the mounting bracket 1. Several mounting slots 4 are provided on the back plate 7. A locking post 5 is fixedly connected inside the mounting slot 4. A locking groove 18 is provided on the post body of the locking post 5. A terminal 6 is fixedly sleeved on the back plate 7. A wire 3 is fixedly connected to the rear end of the terminal 6. A locking box 12 is fixedly connected to the back of the LED bead board 13. An insertion hole 14 is provided on the locking box 12. The insertion hole 14 corresponds to the locking post 5 and is movably sleeved with it. A docking terminal 15 is fixedly installed in the center of the LED bead board 13. The docking terminal 15 corresponds to the terminal and is inserted with it.

[0026] In this design, the present invention achieves rapid installation by using terminal docking and snap-fit ​​5. At the same time, it uses a special quick-release tool and magnetic unlocking via suction cup 24 to achieve quick and effective disassembly, maintenance and replacement, saving time and effort, reducing workload, increasing work efficiency, and minimizing the time lost in the use of the LED splicing screen.

[0027] like Figures 1 to 8 As shown, in a specific embodiment, the locking box 12 is internally equipped with a locking mechanism, which includes a latch 19. The latch 19 corresponds to and engages with the latch slot 18. A first strong magnet 21 is fixedly connected to the other end of the latch 19. The middle portion of the latch 19 is movably connected to the locking box 12 via a shaft. A spring 20 is fixedly connected to the inside of the locking box 12 via a fixing plate. The other end of the spring 20 is fixedly connected to the latch 19. A plurality of LED beads 17 are fixedly mounted on the front side of the LED bead plate 13. 17 is electrically connected to the docking terminal, and a lamp bead frame 16 is fixedly connected to the lamp bead plate 13. The lamp bead frame 16 corresponds to the lamp bead 17 and is sleeved with it. A transparent protective plate 2 is fixedly connected to the other side of the lamp bead frame 16. A handle 11 is fixedly connected to the outside of the suction cup shell 9. A sliding rod 10 is movably installed on the inside of the handle 11. Sliding rods are fixedly connected to both ends of the sliding rod 10. The sliding rods correspond to the sliding grooves opened on the handle 11 and are slidably sleeved with them. A pull rod 25 is fixedly connected to the middle position of the sliding rod 10.

[0028] In this setup, when removing the suction cup, simply unfold the folding plate 8 on the suction cup housing 9, align the suction cup 24 with the center of the display module, press the suction cup 24 onto the surface of the transparent protective plate 2, and at the same time, firmly grip the sliding rod 10 and pull it. At this time, the suction cup 24 will deform due to the pulling of the pull rod 25 and firmly adhere to the surface of the transparent protective plate 2.

[0029] like Figures 1 to 8 As shown, in a specific embodiment, the pull rod 25 passes through the suction cup housing 9 and is movably connected to it. The suction cup housing 9 is provided with a suction cup 24 inside. The center of the suction cup 24 is fixedly connected to the other end of the pull rod 25. A receiving groove is provided on the housing of the suction cup housing 9. A folding plate 8 is movably installed inside the receiving groove. A second strong magnet 22 is fixedly connected to one end of the folding plate 8. The second strong magnet 22 corresponds to the first strong magnet. A protective pad 23 is fixedly connected to the opening of the suction cup housing 9.

[0030] In this setup, the second strong magnet 22 at the end of the folding plate 8 will cause the first strong magnet 21 to move outward. At this time, the card head 19 will separate from the card slot 18, thus unlocking the device. At this time, simply pull the handle 11 to remove the current display module. No quick-release tool is needed for installation. Simply align the display module with the back plate 7 and press it to complete the installation.

[0031] The implementation principle of the magnetic module of the LED splicing screen in this embodiment is as follows:

[0032] This utility model achieves rapid installation by using terminal docking and snap-fit ​​5. At the same time, it uses a special quick-release tool and a suction cup 24 with magnetic unlocking to achieve quick and effective disassembly, maintenance and replacement, saving time and effort, reducing workload, increasing work efficiency, and reducing the time lost in the use of LED splicing screen.

[0033] During removal, simply unfold the folding plate 8 on the suction cup housing 9, align the suction cup 24 with the center of the display module, and press the suction cup 24 onto the surface of the transparent protective plate 2. At the same time, firmly grip the sliding rod 10 and pull it. The suction cup 24 will deform due to the pulling of the lever 25 and adhere tightly to the surface of the transparent protective plate 2. Simultaneously, the second strong magnet 22 at the end of the folding plate 8 will cause the first strong magnet 21 to move outward. This will cause the clip 19 to separate from the slot 18, thus unlocking the device. At this point, simply pull the handle 11 to remove the current display module. During installation, no quick-release tool is needed. Simply align the display module with the back plate 7 and press it down to complete the installation.
