Description

Technical Field

[0001] This utility model belongs to the field of artistic performance technology, specifically relating to an openable and closable dome LED screen structure. Background Technology

[0002] With the increasing demand for artistic performances and large-scale events, LED displays, as a highly efficient visual presentation tool, are widely used in various indoor and outdoor settings. LED screens boast high brightness, superior color performance, and customizable display functions, providing audiences with an excellent visual experience. However, in certain performance scenarios or large spaces, traditional fixed or movable flat LED screens struggle to meet design requirements. Especially in dome-structure settings such as stadiums, large studios, and exhibition centers, traditional LED screens are typically only installed on walls or in front of the stage, failing to fully utilize the dome space to provide a more immersive display effect. Therefore, the performing arts industry has raised higher demands for an LED screen structure that can be installed on a dome and has opening and closing capabilities, allowing for more flexible display effects by opening or closing the screen as needed without affecting the spatial layout or audience visibility.

[0003] Existing dome LED screen structures have several technical shortcomings in practical use. First, traditional dome LED screens are typically fixed installations, lacking flexible opening and closing capabilities. This makes it impossible to effectively conceal the screen when not in use, affecting the visual layout and dynamic effects of the venue. Second, existing LED screen installation structures are generally complex, lacking efficient lifting or position adjustment mechanisms. Staff must rely on external equipment to adjust the screen's height or position, resulting in cumbersome and inefficient operations. Furthermore, most existing LED screen installation structures rely on manual adjustment, making automated control difficult and hindering rapid response capabilities during large-scale events. Additionally, the mobility and adjustment capabilities of dome LED screens are limited in current technology. Due to the unique nature of the dome structure, the hanging and position adjustment of the LED screen heavily depend on fixed hangers and support structures, lacking a flexible hoisting and adjustment system. This makes it difficult to adjust the screen's installation position, thus limiting its application in different scenarios. Therefore, existing dome LED screens have significant room for improvement in terms of practicality and flexibility. Therefore, a new type of openable and closable dome LED screen structure is needed to improve upon these limitations. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 3The present invention provides a technical solution: an openable and closable dome LED screen structure, including: a dome mechanism 1, the dome mechanism 1 including a connecting block 11, a connecting frame 12 between every two connecting blocks 11, an unwinding machine 14 on the connecting block 11, a hook 15 on the unwinding machine 14, and a switching mechanism 2 on the end of the connecting block 11 away from the hook 13.

[0027] The switching mechanism 2 includes a fixed frame 21, an electric box 22 is provided on one side of the fixed frame 21, a rotating rod 23 is provided on one side of the electric box 22, and a double door 24 is provided on one side of the rotating rod 23.

[0028] Both ends of the connecting frame 12 are fixedly connected to the connecting block 11, one end of the hook 13 is fixedly connected to the connecting block 11, one end of the unwinding machine 14 is connected to the hook 13, one end of the hook 15 is connected to the end of the unwinding machine 14 away from the hook 13, one side of the fixing frame 21 is connected to the connecting block 11 and the connecting frame 12, one side of the electric box 22 is fixedly connected to one end of the double door 24, one side of the double door 24 is connected to the side of the fixing frame 21 away from the connecting block 11 and the connecting frame 12, one end of the rotating rod 23 is connected to the electric box 22, and one side of the rotating rod 23 is connected to the double door 24.

[0029] When performing cultural shows using this dome, staff can connect one end of hook 15 to the ceiling, and then connect unwinding machine 14 to hook 13. Staff can then start unwinding machine 14 to retract the line segment of hook 15, thereby raising connecting block 11 and connecting frame 12. Once the target height is reached, staff can stop unwinding machine 14. Staff can then control the electric box 22 to rotate rotating rod 23, thereby controlling the opening and closing of double door 24.

[0030] like Figure 1 - Figure 4 As shown, a lifting mechanism 3 is provided between the two connecting frames 12. The lifting mechanism 3 includes an adjusting arm 31. Both ends of the adjusting arm 31 are provided with a buckle frame 32. An adjusting steel rope 33 is provided on the adjusting arm 31. A crane 34 is provided at one end of the adjusting steel rope 33. A connecting cable 35 is provided on the crane 34.

[0031] Two clips 32 are respectively clipped to both ends of the adjusting arm 31. The end of the clip 32 away from the adjusting arm 31 is clipped to the connecting frame 12. One end of the adjusting steel rope 33 is fixedly connected to the adjusting arm 31. The end of the adjusting steel rope 33 away from the adjusting arm 31 is connected to the crane 34. One end of the connecting cable 35 is limited on the crane 34 for lifting and lowering adjustment.

[0032] After opening the double doors 24, staff can control the crane 34 to move and adjust it on the adjusting arm 31. Once it is in the right position, staff only need to release the connecting cable 35 to lower it with the LED screen for the cultural performance, thus further improving its practicality in actual use.

[0033] The working principle of the above embodiment is as follows: During artistic performances, staff can flexibly control the height and position of equipment and props by operating the dome system to meet various performance needs. First, one end of the hook 15 is connected to the ceiling, and the unwinding machine 14 is connected to the hook 13. After the staff starts the unwinding machine 14, the cable of the hook 15 can be freely wound up and down, thereby controlling the rise or fall of the connecting block 11 and the connecting frame 12. When the connecting block 11 and the connecting frame 12 reach the predetermined height, the staff stops the unwinding machine 14 to fix it in that position. Subsequently, the staff can drive the rotating rod 23 by operating the electric box 22, so that the double door 24 can be opened and closed.

[0034] Once the double doors 24 are opened, staff can further control the crane 34, moving it horizontally along the track of the adjusting arm 31 to select the optimal performance position. Once in the desired position, staff simply release the connecting cable 35, allowing the LED screen to slowly descend to the required height, ready for the performance. This series of operations greatly enhances the flexibility and practicality of the dome system in actual performances.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
