[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Referring to Figures 1, 3, and 5, one embodiment of this utility model provides a detachable LED display screen, comprising a housing 1 and an LED screen 3. A frame 2 is fixedly connected to the side wall of the LED screen 3 to enhance the stability of the overall structure and protect the edges of the display screen. An installation cavity 4 is provided inside the housing 1 to accommodate and limit the position of the LED screen 3, preventing it from shifting during use. An inner edge 5 is provided inside the housing 1, serving as a guide and support, allowing the LED screen 3 to slide smoothly into the housing 1 along the inner edge 5. The LED screen 3 is slidably connected inside the installation cavity 4, and the side wall of the frame 2 is slidably connected inside the housing 1 and abuts against the inner edge 5. This improves assembly efficiency while ensuring the stability of the screen after installation, preventing shaking or loosening. A positioning mechanism is provided on the side wall of the housing 1 for quick... The position of the LED screen 3 is fixed to improve assembly accuracy. A lifting mechanism is provided on the rear side of the housing 1 to facilitate pushing the LED screen 3 outward during disassembly, reducing the burden of manual operation and improving maintenance efficiency. The positioning mechanism includes a fixing pin 8 and a recessed hole 6 opened inside the frame 2. Pull plates 7 are provided on both the left and right sides of the housing 1 for operating the retraction and release of the fixing pin 8. The fixing pin 8 is fixedly connected to the opposite side of the two fixing pins 8. The side wall of the fixing pin 8 is slidably connected to the inside of the housing 1 and the side wall of the fixing pin 8 is slidably connected to the inside of the recessed hole 6. A first spring 9 is sleeved on the side wall of the fixing pin 8. One end of the first spring 9 is fixedly connected to the side wall of the housing 1, and the other end of the first spring 9 is fixedly connected to the side wall of the pull plate 7, providing a restoring force so that the fixing pin 8 can automatically spring back into the recessed hole 6 after the pull plate 7 is released, realizing quick positioning and locking, and improving safety and reliability.

[0032] Referring to Figures 2-4, the lifting mechanism includes a push block 11 and a center block 12. The sidewall of the push block 11 is slidably connected to the inside of the housing 1, and the sidewall of the center block 12 is also slidably connected to the inside of the housing 1. The push block 11 is located at the four corners inside the housing 1, and the center block 12 is located in the middle of the housing 1. This makes the force on the LED screen 3 more even during movement, preventing uneven loading and effectively improving the overall lifting stability and balance. The center block 12 and the sidewall of the slide rod 13 are both fixedly connected to the slide rod 13. The sidewall of the slide rod 13 penetrates the sidewall of the housing 1 and extends to the outside. The sidewall of the slide rod 13 is fixedly connected to the fixing frame 10. Pushing the fixing frame 10 can drive the slide rod 13. The movable frame 10 is located outside the housing 1. The slide rod 13 is fitted with a second spring 14. One end of the second spring 14 is fixedly connected to the side wall of the housing 1, and the other end of the second spring 14 is fixedly connected to the side wall of the frame 10, providing elastic restoring force so that the frame 10 can automatically reset after being pushed. In the locked state, the push block 11 and the center block 12 are completely embedded inside the housing 1, which not only reduces the external space occupation, but also effectively avoids accidental collisions or misoperation, and improves the overall safety. Multiple wire holes 15 for wiring are opened through the inside of the housing 1, which facilitates the arrangement of internal electrical or signal lines.

[0033] Working principle: When installing the LED screen 3 and the housing 1, by pulling the pull plates 7 on both sides, the fixing pin 8 slides outward, leaving installation space inside the housing 1. Then, the LED screen 3 is placed inside the mounting cavity 4, and the frame 2 is attached to the inner edge 5 and level with the housing 1. Then, the pull plates 7 are released, so that the first spring 9 loses the tension force, drives the pull plates 7 to reset, and causes the fixing pin 8 to insert into the inside of the frame 2, locking the position of the frame 2, thereby ensuring the stability of the LED screen 3 installation.

[0034] When it is necessary to remove the LED screen 3 from the inside of the housing 1, pull the pull plate 7 again to pull out the fixing pin 8 from the inside of the frame 2 to release the locking state of the frame 2. Then, push the fixing bracket 10 to make the slide rod 13 slide inside the housing 1. Push the LED screen 3 to move through the push block 11 and the center block 12, so that the frame 2 is separated from the inner edge 5. At this time, the LED screen 3 can be taken out from the inside of the housing 1, thus completing the disassembly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
