Description

Technical Field

[0001] This utility model relates to the field of dome screen technology, and in particular to a multi-channel splicing LED dome screen panoramic display device. Background Technology

[0002] A dome screen is a new type of display system that uses a hyperbolic or spherical screen as its core and achieves 360-degree panoramic image coverage through curved projection technology. Its core advantage lies in breaking the limitations of flat displays. By combining screen shape with projection technology, it creates a spatial perspective effect that closely resembles a real environment, bringing viewers an immersive experience that makes them feel as if they are actually there.

[0003] By projecting images onto a spherical or hyperbolic screen using multiple projectors, edge blending technology is used to eliminate seams and ensure that the image seamlessly covers the entire curved surface.

[0004] Existing dome screens are generally fixed with bolts during installation. However, after long-term use and observation, it has been found that this installation method is inconvenient when the dome screen needs to be frequently installed and disassembled. Therefore, a multi-channel splicing LED dome screen panoramic display device is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-channel spliced ​​LED dome panoramic display device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base, on which multiple sets of support columns are fixedly connected; connecting columns are fixedly connected to the multiple sets of support columns; a first telescopic rod is fixedly connected to the connecting column; a spring is fixedly connected to the connecting column; the first telescopic rod is located inside the spring; pressing blocks are fixedly connected to the ends of the first telescopic rod and the spring; multiple connecting blocks are provided on the base; slots are provided on the connecting blocks; a dome screen body is fixedly connected to the connecting blocks; and supporting columns are fixedly connected between a set of support columns; the supporting columns and connecting blocks are correspondingly arranged.

[0007] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly means that by fixing a first telescopic rod and a spring to the connecting column, and setting a pressing block at the end of the first telescopic rod and the spring, the dome body can be quickly installed in place when it is necessary to install the dome body during use, reducing the troublesome disassembly when using bolts to fix the connecting block during use.

[0008] By fixing a pair of second telescopic rods between the connecting column and the receiving column, the second telescopic rods are compressed when the spring is compressed and stretched when the spring is stretched, which makes the spring run more stably during use and reduces the spring shaking during use.

[0009] By rotating and connecting the first roller to the pressing block, the connecting block can contact the first roller when it moves to the designated position during use, causing the first roller to rotate. This reduces the situation where the connecting block is difficult to continue moving due to excessive friction when it directly contacts the pressing block when it moves to the designated position during use.

[0010] By fixing a support plate to the support column, the support plate can be used to support the connecting block when it moves to the designated position during use, reducing the possibility of damage to the pressing block due to the small contact point between the connecting block and the support column when the pressing block is pressed on during use;

[0011] By rotating multiple second rollers on the receiving plate, the connecting block and the second rollers can come into contact and rotate when the connecting block moves toward the support column. This reduces the situation where the connecting block is difficult to move toward the support column due to excessive friction when it directly contacts the receiving plate during use.

[0012] By fixing multiple rubber strips in the slot, the first roller can contact the rubber strips during use, thereby increasing the friction between the first roller and the slot and further reducing the shaking of the connecting block during use.

[0013] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Please see Figures 1 to 4This utility model provides a multi-channel spliced ​​LED dome panoramic display device, including a base 1. Multiple sets of support columns 11 are fixedly connected to the base 1. Connecting columns 12 are fixedly connected to the support columns 11. A first telescopic rod 13 is fixedly connected to the connecting column 12. A spring 14 is fixedly connected to the connecting column 12. The first telescopic rod 13 is located inside the spring 14. Pressing blocks 15 are fixedly connected to the ends of the first telescopic rod 13 and the spring 14. Multiple connecting blocks 16 are provided on the base 1, and slots 17 are formed on the connecting blocks 16. The dome screen body 18 is fixedly connected to the connecting block 16, and a receiving column 19 is fixedly connected between a group of support columns 11. The receiving column 19 and the connecting block 16 are correspondingly arranged. When the dome screen body 18 needs to be installed, the dome screen body 18 is pushed towards the support column 11. When the base 1 moves, it drives the connecting block 16 to move accordingly. When the connecting block 16 moves to the designated position, the connecting block 16 contacts the pressing block 15. When the connecting block 16 continues to move towards the support column 11, the connecting block 16 presses against the pressing block 15. The pressing block 15 is pressed, causing it to move towards the connecting column 12. As the pressing block 15 moves towards the connecting column 12, the first telescopic rod 13 and the spring 14 are compressed. When the first telescopic rod 13 and the spring 14 are compressed to the designated position, the pressing block 15 moves into the slot 17 on the connecting block 16. At this time, under the elastic force of the spring 14, the pressing block 15 is pushed towards the connecting block 16. When the pressing block 15 moves to the designated position, it presses the connecting block 16, pressing it towards the receiving column 19 and fixing it in place. By fixing the first telescopic rod 13 and the spring 14 to the connecting column 12 and providing the pressing block 15 at the ends of the first telescopic rod 13 and the spring 14, the dome body 18 can be quickly installed when it needs to be installed during use, reducing the troublesome disassembly when using bolts to fix the connecting block 16 during use.

[0022] Please see Figures 1 to 4 A pair of second telescopic rods 2 are fixedly connected to the connecting column 12. The other end of the second telescopic rod 2 is fixedly connected to the pressing block 15. When the connecting block 16 moves to the designated position in the direction of the pressing block 15, the first telescopic rod 13 and the spring 14 are compressed. When the first telescopic rod 13 and the spring 14 are compressed, the pair of second telescopic rods 2 are compressed accordingly. When the spring 14 pushes the pressing block 15 in the direction of the receiving column 19, the second telescopic rods 2 are stretched accordingly. By fixing a pair of second telescopic rods 2 between the connecting column 12 and the receiving column 19, the second telescopic rods 2 are compressed when the spring 14 is compressed and stretched when the spring 14 is stretched, which makes the spring 14 run more stably during use and reduces the shaking of the spring 14 during use.

[0023] Please see Figures 1 to 4 A first roller 3 is rotatably connected to the pressing block 15. The first roller 3 is located between the second roller 5 and the supporting column 19. When the connecting block 16 moves to the designated position in the direction of the pressing block 15, the connecting block 16 and the first roller 3 come into contact. At this time, the first roller 3 rotates. When the first roller 3 rotates, the connecting block 16 moves smoothly in the direction of the supporting column 11. By rotatably connecting the first roller 3 to the pressing block 15, the connecting block 16 can come into contact with the first roller 3 when it moves to the designated position during use, so that the first roller 3 rotates. This can reduce the situation where the connecting block 16 is difficult to continue moving due to large friction when it directly contacts the pressing block 15 when it moves to the designated position during use.

[0024] Please see Figures 1 to 4 A receiving plate 4 is fixedly connected to the receiving column 19. The receiving plate 4 is located below the connecting block 16. When the connecting block 16 moves to the designated position in the direction of the pressing block 15, the connecting block 16 and the receiving plate 4 come into contact. At this time, the receiving plate 4 supports the connecting block 16. By fixing the receiving plate 4 to the receiving column 19, the connecting block 16 can be supported when it moves to the designated position during use. This reduces the possibility of damage to the pressing block 15 when it is pressed by the pressing block 15 during use due to the small contact point between the connecting block 16 and the receiving column 19.

[0025] Please see Figures 1 to 4 The receiving plate 4 is rotatably connected to a second roller 5, which is arranged in an array. When the connecting block 16 is placed on the receiving plate 4, the connecting block 16 and the second roller 5 come into contact. When the connecting block 16 continues to move toward the support column 11, the second roller 5 rotates. At this time, the connecting block 16 moves smoothly toward the support column 11. By rotatably connecting multiple second rollers 5 on the receiving plate 4, the connecting block 16 can come into contact with the second roller 5 and rotate when it moves toward the support column 11. This can reduce the situation where the connecting block 16 is difficult to move toward the support column 11 due to excessive friction when it directly contacts the receiving plate 4 during use.

[0026] Please see Figures 1 to 4 Multiple rubber strips 6 are fixedly connected in the slot 17. The rubber strips 6 are arranged in an array. When the connecting block 16 moves to the designated position, the first roller 3 enters the slot 17 and contacts the slot 17. By fixing multiple rubber strips 6 in the slot 17, the first roller 3 and the rubber strips 6 can contact each other during use, thereby increasing the friction between the first roller 3 and the slot 17 and further reducing the shaking of the connecting block 16 during use.

[0027] Working principle: When the dome body 18 needs to be installed, it is pushed towards the support column 11. When the base 1 moves, it drives the connecting block 16 to move accordingly. When the connecting block 16 moves to the designated position, it contacts the pressing block 15. As the connecting block 16 continues to move towards the support column 11, it presses the pressing block 15. At this time, the pressing block 15 is pressed towards the connecting column 12. When the pressing block 15 moves towards the connecting column 12, the first telescopic rod 13 and the spring 14 are compressed. When compressed to the designated position, the pressing block 15 moves into the slot 17 on the connecting block 16. At this time, under the elastic force of the spring 14, the pressing block 15 is pushed towards the connecting block 16. When the pressing block 15 moves to the designated position, it presses the connecting block 16, pressing it towards the receiving post 19 and fixing it. When the connecting block 16 moves towards the pressing block 15 to the designated position, the first telescopic rod 13 and the spring 14 are compressed. When the first telescopic rod 13 and the spring 14 are compressed, a pair of second telescopic rods... The telescopic rod 2 is compressed accordingly. When the spring 14 pushes the pressing block 15 towards the receiving column 19, the second telescopic rod 2 is stretched. When the connecting block 16 moves to the designated position towards the pressing block 15, the connecting block 16 contacts the first roller 3. At this time, the first roller 3 rotates. When the first roller 3 rotates, the connecting block 16 moves smoothly towards the support column 11. When the connecting block 16 moves to the designated position towards the pressing block 15, the connecting block 16 contacts the receiving plate 4. At this time, the receiving plate 4 supports the connecting block 16. When the connecting block 16 is placed on the receiving plate 4, the connecting... When the connecting block 16 and the second roller 5 come into contact, the second roller 5 rotates as the connecting block 16 continues to move toward the support column 11. At this time, the connecting block 16 moves smoothly toward the support column 11. When the connecting block 16 moves to the designated position, the first roller 3 enters the slot 17 and comes into contact with the slot 17. By fixing multiple rubber strips 6 in the slot 17, the first roller 3 and the rubber strips 6 can come into contact during use, thereby increasing the friction between the first roller 3 and the slot 17 and further reducing the shaking of the connecting block 16 during use.
