Description

Technical Field

[0001] The utility model belongs to the technical field of dome technology, and particularly relates to a bracket structure of a dome device. Background Art

[0002] A dome is a special projection display device, whose screen is in a hemispherical or spherical structure. An image is projected onto the spherical surface through a projection system, which can provide an immersive visual experience for the audience. The dome covers a wide field of view of the audience, enabling the display content to be presented simultaneously from multiple angles, enhancing the visual impact and sense of presence. This design makes the dome particularly suitable for scenes that require a high degree of immersion, providing a more realistic visual effect than traditional flat screens.

[0003] During the installation of existing domes, due to the influence of uneven ground, it is often difficult to achieve precise micro-adjustment. In this case, the dome may be inclined or uneven, resulting in distortion of the projection image and affecting the viewing experience of the audience. In addition, the uneven ground will also increase the installation difficulty and debugging time, greatly reducing the stability and installation efficiency of the system. Therefore, a bracket structure of a dome device is proposed to solve the above problems. Summary of the Utility Model

[0004] In view of one or more of the above defects or improvement requirements in the prior art, the utility model provides a bracket structure of a dome device, which has the advantages of precise adjustment, improved projection quality, and convenient installation and debugging of the dome.

[0007] The lifting component includes a mounting plate. On one side of the upper end surface of the mounting plate, two limiting blocks are assembled and the two limiting blocks are arranged parallel to each other in opposite directions. A slider is slidably arranged between the two limiting blocks. On the upper end surface of the mounting plate, two sliding rods are also assembled and the two sliding rods are respectively located on one side of the two limiting blocks.

A mounting block is assembled on the lower end surface of the top plate and the mounting block is located between the two sleeves. A groove is arranged at the lower end of the mounting block and a roller is rotatably connected in the groove through a rotating shaft. The upper ends of the two sliding rods both penetrate through the top plate, and a lifting block is assembled at the center point of the upper end surface of the top plate.

[0008] As a further improvement of the utility model, a connecting keel is assembled at the lower end of the dome body, and a fixing plate is arranged at the lower end of the connecting keel and is connected to the upper ends of a number of lifting blocks.

[0009] As a further improvement of the present utility model, two ladder frames are assembled on the upper end surface of the bottom plate, and the two ladder frames are arranged in parallel facing each other.

[0020] Embodiment

[0021] Provided by Figures 1-4 There is a support structure of a globe screen device, including a base plate 1 and a globe screen body 2;

[0022] A number of lifting assemblies 3 are assembled around the upper end face of the base plate 1;

[0023] The lifting assembly 3 includes a mounting plate 30. On one side of the upper end face of the mounting plate 30, two limiting blocks 31 are assembled and the two limiting blocks 31 are arranged in parallel facing each other. A slide block 32 is slidably arranged between the two limiting blocks 31. On the upper end face of the mounting plate 30, two slide rods 33 are also assembled and the two slide rods 33 are respectively located on one side of the two limiting blocks 31. The two slide rods 33 are arranged in parallel and sleeves 34 are sleeved on the outside of both of them. The upper end faces of the two sleeves 34 are jointly assembled with a top plate 35. A mounting block 36 is assembled on the lower end face of the top plate 35 and the mounting block 36 is located between the two sleeves 34. A groove is provided at the lower end of the mounting block 36 and a roller 37 is rotatably connected in the groove through a rotating shaft. The upper ends of the two slide rods 33 both penetrate through the top plate 35, and a lifting block 38 is assembled at the center point of the upper end face of the top plate 35;

[0024] A connecting keel 21 is assembled at the lower end of the globe screen body 2. A fixed plate 22 is provided at the lower end of the connecting keel 21 and the fixed plate 22 is connected to the upper ends of a number of lifting blocks 38.

[0025] In this embodiment, through the mutual cooperation of the components within the lifting assembly 3, by controlling the guide rod cylinder 39, the lifting block 38 can be driven to rise. By installing several groups of lifting assemblies 3 around the lower end of the spherical screen body 2, precise fine-tuning of the height and tilt angle of the spherical screen body 2 can be achieved. The lifting block 38 driven by the guide rod cylinder 39 can lift and lower smoothly, effectively eliminating the influence caused by the uneven ground, ensuring the flatness and stability of the spherical screen body 2. Since the height and angle of the spherical screen body 2 can be precisely adjusted, the projection image is not prone to distortion or tilt, significantly improving the viewing effect. The audience will be able to experience a clearer and more realistic projection image, enhancing the sense of immersion and visual enjoyment. Compared with the traditional fixed support structure, this device can flexibly adjust the height and angle of the spherical screen body 2 during the installation and debugging process, reducing the difficulties and errors during installation. This not only shortens the installation and debugging time, but also reduces the work intensity of the operators and improves the overall installation efficiency.

[0026] Specifically, referring to Figures 1-2 , two ladder frames 11 are assembled on the upper end surface of the bottom plate 1, and the two ladder frames 11 are arranged parallel to each other in opposite directions. The two ladder frames 11 are respectively disposed on the opposite sides of the spherical screen body 2, and a connecting plate 12 is assembled between the two ladder frames 11.

[0027] In this embodiment, the provided ladder frames 11 can facilitate the audience to enter the spherical screen body 2 for viewing.

[0028] Specifically, referring to Figures 1-4 , a guide rod cylinder 39 is assembled on one side of the upper end surface of the bottom plate 1. The output end of the guide rod cylinder 39 is connected with a cylinder guide rod 391, and one end of the cylinder guide rod 391 is connected with one side of the slider 32.

[0029] In this embodiment, by controlling the guide rod cylinder 39, the guide rod cylinder 39 drives the cylinder guide rod 391 to push the slider 32 at one end, and finally the lifting block 38 can be driven to rise.

[0030] Specifically, referring to Figures 3-4 , the upper end of the slider 32 is provided with an inclined surface.

[0031] In this embodiment, by providing an inclined surface at the upper end of the slider 32, when the slider 32 moves, it pushes the roller 37, so that the roller 37 moves on the inclined surface of the slider 32 and gradually rises.

[0032] The support structure of the spherical screen device of the present utility model:

[0033] During actual use, when it is necessary to finely adjust the height or angle of the spherical screen body 2, the guide rod cylinder 39 in the specified area is connected to an external air source and an output value is given to the cylinder. Subsequently, the guide rod cylinder 39 is controlled so that the guide rod cylinder 39 drives the cylinder guide rod 391 connected to the output end to push the slider 32 to one side. Through the limitation of the slider 32 by the two limit blocks 31, when the slider 32 moves, the inclined surface at the upper end pushes the provided roller 37, so that the roller 37 and the provided jacking block 38 are pushed upward, thereby pushing a part at the lower end of the spherical screen body 2, so as to finely adjust the height or angle of the spherical screen body 2.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
