[0002] A modular LED screen is a high-definition display system composed of multiple standardized LED modules. Each module integrates LED beads, driver circuits, and cabinet structure, supporting rapid assembly and flexible expansion.
[0003] Due to design tolerances or interface wear, the data cable connection points of modular screens are prone to loosening and wobbling. This is especially true in environments with frequent plugging and unplugging or long-term vibration (such as outdoor advertising screens and stage equipment), which can lead to poor contact and unstable signal transmission, manifesting as screen flickering, signal interruption, or abnormal color.
[0004] How to design a modular, quick-release LED display to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Example, refer to Figures 1-6 A modular quick-release LED display includes a front shell 1 and a rear shell 3. A modular screen 2 is fixedly connected to the inner wall of the front shell 1. A connecting plate 4 is provided on the back of the rear shell 3. Multiple quick-release screws are provided on the connecting plate 4. Multiple screw holes are provided on the rear shell 3. The rear shell 3 is fixedly connected to the connecting plate 4 by quick-release screws. The quick-release screw includes a screw body 5 and a rotating part 6. The rotating part 6 is rotatably connected to the head of the screw body 5. A fixing plate 7 is fixedly connected to the inner wall of the rear shell 3. A main airbag 9 is fixedly connected to the inner wall of the fixing plate 7. A compression plate 10 is fixedly connected to the outer wall of the main airbag 9. A push plate 11 is fixedly connected to the side wall of the connecting plate 4. The push plate 11 is located inside the through groove 8.
[0025] A slot is provided at the bottom edge of the rear shell 3. A connecting seat 12 is fixedly connected to the slot of the rear shell 3. A partition 13 is fixedly connected to the inner wall of the connecting seat 12. The partition 13 divides the connecting seat 12 into a plug cavity and an airbag cavity. A compression port 15 is provided on the partition 13. An inflatable airbag 14 is fixedly connected to the inner wall of the airbag cavity. A connecting tube 16 is fixedly connected to the inflatable airbag 14. The front shell 1 and the rear shell 3 are fixedly connected by screws. The connecting plate 4 is fixedly connected to the external connecting bracket. A through groove 8 is provided on the rear shell 3. The through groove 8 corresponds to the position of the fixing plate 7. The main airbag 9 is located between the fixing plate 7 and the rear shell 3. The compression port 15 connects the plug cavity and the airbag cavity. The main airbag 9 and the inflatable airbag 14 are connected by the connecting tube 16, which is located on the inner side of the rear shell 3.
[0026] The airbags in this modular screen are made of polyurethane (PU), a material renowned for its superior elasticity and abrasion resistance. This allows the airbags to maintain excellent physical properties during repeated compression and release, ensuring long-term reliability and stability. Furthermore, polyurethane possesses excellent tear resistance and chemical corrosion resistance, enabling it to withstand various potential damages in harsh working environments and extending the equipment's lifespan. Its good weather resistance means that even after prolonged exposure to the external environment, it can effectively resist aging caused by ultraviolet radiation, ensuring the airbag's function remains unchanged over time.
[0027] By setting a rotating part 6 on the screw body 5, the operator can rotate the screw body 5 by pinching the rotating part 6. The screw body 5 can be installed and tightened without the need for disassembly tools, which is more convenient. The rotation design of the screw body 5 and the rotating part 6 saves space occupied by the screw body 5 and is more aesthetically pleasing.
[0028] The working principle of this modular quick-release LED display is as follows: If it is necessary to connect the modular screen to the external bracket, align the multiple screw holes on the back shell 3 with the holes reserved on the connecting plate 4, and then install the screw body 5 inside the screw holes of the back shell 3. By rotating the rotating part 6, the connecting plate 4 and the back shell 3 are tightly fixed.
[0029] To connect the modular screen, first connect the screen to the connecting plate 4 using the screw body 5. Then insert the plug into the plug cavity of the connector 12 and tighten the screw body 5 using the rotating part 6. During the tightening process, the connecting plate 4 and the back shell 3 gradually approach each other, and the push plate 11 on the connecting plate 4 gradually moves towards the main airbag 9, squeezing the main airbag 9. This causes the air inside the main airbag 9 to be pressurized and enter the interior of the expansion airbag 14 through the connecting tube 16. The outer wall of the expansion airbag 14 is compressed and expands into the interior of the plug cavity through the extrusion port 15, contacting the side wall of the plug. Through the friction generated by the extrusion, the plug is pressed tightly against the inner side wall of the connector 12, making the connection between the two more secure and preventing the plug from shaking inside the connector 12, thus ensuring the quality of signal transmission.
[0030] During the aforementioned process, the main airbag 9 deforms under pressure. The elastic properties of its material generate a counterforce (i.e., a reverse thrust) on the push plate 11 and the connecting structure. This force is fed back through the connecting structure to the connection between the screw body 5 and the rear shell 3, forming a certain preload. This reverse thrust effectively enhances the stability of the entire connection system, offsetting some of the external forces that could cause the screw to loosen under dynamic loads such as external vibrations, thus preventing the screw body 5 from loosening due to vibration. Compared to traditional methods that rely solely on thread friction for anti-loosening, this design achieves an active anti-loosening mechanism through the physical properties of the airbag, not only improving the overall structural reliability but also reducing the frequency of subsequent maintenance.
[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
