Technical Field

[0001] This utility model relates to the field of LED screen technology, and in particular to a modular LED screen structure for dome theaters. Background Technology

[0002] Dome theaters offer audiences an unprecedented immersive experience through their unique hemispherical screen design. Audiences are completely surrounded by the screen, significantly expanding their field of vision. This design makes them feel as if they are actually in the film scene, experiencing a powerful sense of presence without any auxiliary equipment.

[0003] Traditional dome theaters use projection technology to play films. In recent years, dome theaters have gradually shifted from projection technology to LED screen playback. LED screen playback can bring a more immersive experience to the audience. The LED screen of a dome theater is composed of multiple LED screen components, which are installed on the top ring frame of the dome theater. The connection between the LED screen components requires multiple sets of bolts, which takes a lot of time to install, resulting in relatively low overall installation efficiency.

A connecting frame 15 is slidably connected to the end of the flange bearing 14, and a push block 16 is fixedly connected to the end of the connecting frame 15. The push block 16 slides within the through hole 13. A bearing seat 17 is fixedly installed on one side of the mounting module 1. A threaded rod 18 is rotatably connected to one end of the bearing seat 17. The threaded rod 18 is threadedly connected to the connecting frame 15, and an anti-slip handle 19 is fixedly connected to one end of the threaded rod 18. One side of the locking block 7 is an inclined surface. The other side is flat. The end of the locking block 7 has a beveled cut. One side of the push block 16 is a bevel, and the beveled side of the push block 16 contacts the beveled cut at the end of the locking block 7. The push block 16 is used to press the locking block 7. When connecting the LED screen components, the locking head 3 on one side of the mounting module 1 is inserted into the positioning groove 5 on the other side of the mounting module 1. When the locking block 7 moves to the slot 11, under the action of the spring 9, the locking block 7 and the slot 11 are matched, thus realizing the connection between the mounting modules 1. The telescopic rod 8 is used for To ensure the stability of the spring 9 during deformation, during the process of inserting the clamp head 3 into the positioning slot 1 5, the positioning head 4 is simultaneously inserted into the positioning slot 2 6. The arrangement of the positioning slot 2 6 and the positioning head 4 not only improves the adaptation speed, but also strengthens the overall structural strength of the positioning head 4. When it is necessary to disassemble the connection between the installation modules 1, rotate the anti-slip handle 19. The push block 16 provided at the end of the connecting bracket 15 will press the oblique cut at the end of the clamp block 7 during the movement, causing the clamp block 7 to retract into the clamp head 3. At this time, the connection between the two installation modules 1 is disconnected.

[0025] Please see Figure 1 and Figure 6In this embodiment, connecting shafts 20 are fixedly installed at both ends of the installation module 1, and support frames 21 are fixedly installed at both ends of the installation module 1.

The handles 25 are used to carry the installation module 1. After the connecting shafts 20 and the surface holes of the connecting seats 22 are matched, the connecting shafts 20 play a role in further strengthening the connection strength. The support frames 21 are used to support the connecting shafts 20. The flange bearings 23 are slidably connected to the surface of the connecting shafts 20, thus ensuring the stability of the connection of the connecting shafts 20. The handles 25 fixedly installed in the grooves 24 facilitate the carrying of the installation module 1 and also provide a grip for the connection of the installation module 1.

[0026] During production, the LED screen is pre-installed with bolts at the mounting screw holes 2 on the surface of the mounting module 1. When connecting the LED screen components, the clip 3 on one side of the mounting module 1 is inserted into the positioning groove 5 on the side of another mounting module 1. During the insertion process, one side of the clip 7 is squeezed back into the clip 3 by the edge of the positioning groove 5. When the clip 7 moves to the slot 11, under the action of the spring 9, the clip 7 and the slot 11 are matched, thus realizing the connection between the mounting modules 1.

[0027] A telescopic rod 8 is provided between the two locking blocks 7. The telescopic rod 8 is used to ensure the stability when the spring 9 is deformed. The limiting block 10 at the end of the locking block 7 is used to ensure the stability of the movement of the locking block 7.

The flange bearing 23 is slidably connected to the surface of the connecting shaft 20, thus ensuring the stability of the connection of the connecting shaft 20.

[0030] When it is necessary to disassemble the connection between the installation modules 1, rotate the anti-slip handle 19, the threaded rod 18 rotates at the bearing seat 17, and the connecting bracket 15 connected to the threaded rod 18 moves. During the movement, the push block 16 at the end of the connecting bracket 15 presses the oblique cut at the end of the locking block 7, causing the locking block 7 to retract into the locking head 3. At this time, the connection between the two installation modules 1 is disconnected. The flange bearing 14 is used to ensure the stability of the push block 16 movement.

[0031] The handle 25 fixedly installed in the groove 24 facilitates the handling of the installation module 1 and also provides a grip for connecting the installation module 1.

[0032] Through the above steps, when connecting the LED screen components of the modular LED screen structure for dome theaters, the clip 3 is inserted into the positioning slot 5 to achieve the connection between the installation modules 1. There is no need to use multiple sets of bolts for connection. The positioning head 4, the connecting shaft 20 and the connecting seat 22 ensure the strength of the connection. In this way, the installation speed is greatly improved while ensuring the strength.
