[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0029] See attached document Figure 1 -Appendix Figure 5 The present invention provides an outdoor LED screen, including an outdoor LED screen body 1, a protective shell 2 on the outside of the outdoor LED screen body 1, the protective shell 2 being a square structure, a tray 3 fixedly connected to the bottom of the protective shell 2, and a cover plate 4 on the top of the protective shell 2, the cover plate 4 being movably connected to the protective shell 2 by a hinge.
[0030] The lifting mechanism is located inside the protective shell 2 and is used to lift the outdoor LED screen body 1.
[0031] The lifting mechanism includes two hydraulic rods 5, which are respectively located on both sides of the protective shell 2. Fixing plates 6 are fixedly connected to both sides of the protective shell 2, and the two fixing plates 6 are respectively fixedly connected to the bottom of the two hydraulic rods 5.
[0032] The lifting mechanism also includes two lifting plates 7, which are respectively located on both sides of the protective shell 2, and are respectively fixedly connected to the top of two hydraulic rods 5;
[0033] In this implementation scheme, when the LED screen needs to be used, the cover plate 4 is opened, the user starts the hydraulic rod 5 to work, so that the outdoor LED screen body 1 is raised. When it is raised to the maximum extent, the locking rod pops out and enters the interior of the movable frame 23. Then the electric telescopic rod 22 is activated to retract, so that the movable rod 15 rotates, thereby raising the outdoor LED screen body 1 again.
[0034] To achieve the purpose of lifting the device, the following technical solution is adopted: The lifting mechanism also includes two lifting rods 8, and two sliders 9 are embedded inside the protective shell 2. The two sliders 9 are fixedly connected to the inner ends of the two lifting rods 8 respectively. Two limiting strips 10 are fixedly provided on the rear side of the outdoor LED screen body 1. Both limiting strips 10 slide with the protective shell 2. A stop block 11 is fixedly sleeved on the top of the two limiting strips 10. The sliders 9 are sleeved on the two limiting strips 10 and slide with the limiting strips 10.
[0035] The user activates the extension of the two hydraulic rods 5, which in turn causes the two lifting blocks and the lifting rod 8 to move upward. The upward movement of the lifting rod 8 causes the slider 9 to move upward, and the upward movement of the slider 9 causes the limit bar 10 and the outdoor LED screen body 1 to move upward, thus raising the outdoor LED screen body 1.
[0036] To achieve the purpose of lifting the device again, the following technical solution is adopted: The lifting mechanism also includes a positioning rail 12, which is fixedly installed on the rear side of the outdoor LED screen body 1. Two positioning blocks 13 are provided inside the positioning rail 12, and both positioning blocks 13 are slidably connected to the positioning rail 12. A first round rod 14 is fixedly connected inside each of the two positioning blocks 13. Movable rods 15 are sleeved on the outer sides of each of the two first round rods 14. The movable rods 15 are movably connected to the first round rods 14 through rolling bearings. The two movable rods 15 are movably connected to each other through bearings. A second round rod 16 is embedded at the bottom of each of the two movable rods 15. Movable grooves are opened inside each of the two movable grooves, and locking blocks are embedded inside each of the two movable grooves. 17. Springs 18 are fixedly embedded inside the two movable slots. The two springs 18 are fixedly connected to the two snap-fit blocks 17 respectively. A horizontal plate is fixedly connected to the rear side of the protective shell 2. Electric push rods 19 are fixedly connected to both sides of the horizontal plate. Moving blocks 20 are fixedly connected to the outer ends of the two electric push rods 19. Support frames 21 are fixedly connected to the top of the two moving blocks 20. Telescopic rods 22 are fixedly connected to the rear side of the two support frames 21. Moving frames 23 are fixedly connected to the rear end of the two telescopic rods 22. Stop bars 24 are fixedly connected to the front side of the two moving frames 23. A through groove is provided on the rear side of the protective shell 2. The through groove matches the two snap-fit blocks 17. A second spring 25 is embedded inside the positioning rail 12. The second spring 25 is fixedly connected between the two positioning blocks 13.
[0037] When the outdoor LED screen body 1 is raised to its maximum height, the locking rod pops out and enters the moving frame 23. At this time, the user activates the electric telescopic rod 22 to retract. The retraction of the electric telescopic rod 22 drives the moving block 20 and the moving frame 23 to move. The movement of the moving frame 23 drives the locking rod and the second round rod 16 to move, thereby driving the two movable rods 15 to rotate. The rotation of the two movable rods 15 causes the two positioning blocks 13 to move inward inside the two positioning tracks 12, thereby causing the outdoor LED screen body 1 to be raised again.
[0038] The usage process of this utility model is as follows: When the LED screen needs to be used, open the cover plate 4, and the user starts the hydraulic rod 5 to work, causing the outdoor LED screen body 1 to rise. When it is raised to the maximum extent, the locking rod pops out and enters the movable frame 23. Then, start the electric telescopic rod 22 to retract, causing the movable rod 15 to rotate, thereby raising the outdoor LED screen body 1 again. The user starts the two hydraulic rods 5 to extend, and the extension of the hydraulic rods 5 drives the two lifting blocks and the lifting rod 8 to move upward. The upward movement of the lifting rod 8 drives the slider 9 to move upward, and the upward movement of the slider 9 drives the limit strip 10 and the outdoor LED screen body 1 to move upward. The D-screen body 1 moves upward, causing the outdoor LED screen body 1 to rise. When the outdoor LED screen body 1 is raised to its maximum extent, the locking rod pops out and enters the moving frame 23. At this time, the user activates the electric telescopic rod 22 to retract. The retraction of the electric telescopic rod 22 drives the moving block 20 and the moving frame 23 to move. The movement of the moving frame 23 drives the locking rod and the second round rod 16 to move, thereby driving the two movable rods 15 to rotate. The rotation of the two movable rods 15 causes the two positioning blocks 13 to move inward inside the two positioning tracks 12, thereby causing the outdoor LED screen body 1 to rise again.
[0039] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
