[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the attached drawings of the present invention, and they do not specifically limit the present invention.

[0029] Embodiment 1: A virtual reality public art device, as Figures 1 - 10As shown in the figure, it includes an installation cylinder 1, an electric suction cup 101, a transparent cover 2, a guide rod 3, a large ring 4, a connecting block 5, a small ring 6, a sliding frame 7, a first spring 71, a connecting rod 8, a connecting ring 81, an elastic telescopic rod 82, a sliding block 83, a projector 9, a connecting shaft 10, a spring telescopic rod 11, a mounting plate 12, a first motor 13, an adjusting component and a disconnecting component. The lower part of the installation cylinder 1 is fixedly connected with electric suction cups 101 evenly distributed in a circle at the circumference. A transparent cover 2 is fixedly connected inside the installation cylinder 1. A guide rod 3 is fixedly connected to the lower part inside the transparent cover 2. A large ring 4 is slidably connected to the guide rod 3. Connecting blocks 5 evenly distributed in a circle at the circumference are fixedly connected to the large ring 4. A small ring 6 is fixedly connected between the upper parts of the connecting blocks 5 evenly distributed in a circle at the circumference. A sliding frame 7 is slidably connected to the left part of the small ring 6. A first spring 71 is connected between the sliding frame 7 and the small ring 6. The top end of the sliding frame 7 is rotatably connected with a connecting rod 8. The top end of the connecting rod 8 is rotatably connected with a connecting ring 81. An elastic telescopic rod 82 is fixedly connected to the right part of the small ring 6. The telescopic end of the elastic telescopic rod 82 is rotatably connected with a sliding block 83. The sliding block 83 is slidably connected with the connecting ring 81. A projector 9 is rotatably connected to the connecting ring 81. The lower side of the projector 9 is connected with a connecting shaft 10 through a universal coupling. Spring telescopic rods 11 evenly distributed in a circle at the circumference are fixedly connected to the lower side of the large ring 4. A mounting plate 12 is fixedly connected between the bottom ends of the spring telescopic rods 11 evenly distributed in a circle at the circumference. A first motor 13 is fixedly connected to the mounting plate 12. A transverse rib is provided on the output shaft of the first motor 13. A transverse groove is provided at the bottom end of the connecting shaft 10. The connecting shaft 10 is clamped with the output shaft of the first motor 13. An adjusting component for adjusting the projection position and angle is provided on the installation cylinder 1 and the transparent cover 2. A disconnecting component for controlling the disconnection of the first motor 13 and the connecting shaft 10 is provided on the installation cylinder 1 and the transparent cover 2.

[0030] When using this device, the staff fixes the device to a proper position through the electric suction cup 101, and then projects the image into the transparent cover 2 through the projector 9. During projection, the output shaft of the first motor 13 rotates to drive the connecting shaft 10 to rotate. The rotation of the connecting shaft 10 drives the projector 9 to rotate on the connecting rod 8, and the projected image can be rotated. When the audience wants to touch the virtual image, the large ring 4 can be controlled to slide upward on the guide rod 3 through the adjustment component. The upward sliding of the large ring 4 drives components such as the connecting block 5, the small ring 6, the sliding frame 7, the connecting ring 81 and the projector 9 to move upward together. After the projector 9 moves upward, the projected image is located outside the transparent cover 2. At the same time, the sliding frame 7 can also be controlled to slide downward through the adjustment component, and the first spring 71 deforms. The downward sliding of the sliding frame 7 pulls the left part of the connecting ring 81 to tilt downward through the connecting rod 8, and the right part of the connecting ring 81 tilts upward. The elastic telescopic rod 82 is pulled to extend through the sliding block 83. The tilting of the connecting ring 81 also drives the projector 9 to tilt, thereby changing the projection angle of the projector 9. The disconnection component can control the mounting plate 12 to move downward, and the spring telescopic rod 11 extends. The downward movement of the mounting plate 12 drives the first motor 13 to move downward and disconnect from the connecting shaft 10, thereby controlling the projector 9 to stop rotating so that the audience can better observe the projected image. When normal projection needs to be restored, the audience controls the disconnection component and the adjustment component to reset. At this time, the spring telescopic rod 11 shortens to drive the mounting plate 12 and the first motor 13 to move upward and reset, so that the first motor 13 is reconnected to the connecting shaft 10 again. At this time, the connecting shaft 10 can drive the projector 9 to rotate again. Under the action of the reset of the first spring 71, the sliding frame 7 slides upward and resets accordingly. The upward sliding of the sliding frame 7 pushes the connecting ring 81 to rotate into a horizontal state through the connecting rod 8, so that the projector 9 is reset to the horizontal state for projection. When the adjustment component resets, it will also drive the large ring 4 to slide downward, thereby driving components such as the connecting block 5, the small ring 6, the sliding frame 7, the connecting ring 81 and the projector 9 to move downward and reset together. At this time, the image projected by the projector 9 is located inside the transparent cover 2. In this way, it can be adjusted by the audience themselves when watching the virtual image, improving the personalization and interactivity.

[0031] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the adjustment assembly includes a second motor 14, a threaded rod 15, a connecting plate 16, an adjustment rod 17, a top cover 18, a contact button 19, and a contact block 20. The lower part inside the installation cylinder 1 is fixedly connected with a second motor 14. The output shaft of the second motor 14 is fixedly connected with a threaded rod 15. The threaded rod 15 extends into the transparent cover 2 and is rotationally connected to the transparent cover 2. The threaded rod 15 is threadedly connected to the large ring 4. The bottom end of the sliding frame 7 is fixedly connected with a connecting plate 16. The middle left part of the transparent cover 2 is threadedly connected with an adjustment rod 17. The top end of the adjustment rod 17 is provided with a knob. The adjustment rod 17 is in pressing fit with the connecting plate 16. The top end of the transparent cover 2 is rotationally connected with a top cover 18. The rotational connection part between the transparent cover 2 and the top cover 18 is fixedly connected with a contact button 19. The contact button 19 is electrically connected to the second motor 14. The rotational connection part between the top cover 18 and the transparent cover 2 is fixedly connected with a contact block 20. The contact block 20 is in pressing fit with the contact button 19.

[0032] When the audience wants to touch the virtual image closely, control the top cover 18 to rotate and open. The rotation of the top cover 18 drives the contact block 20 to rotate and press the contact button 19. The contact button 19 controls the operation of the second motor 14 through the controller. The operation of the second motor 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 drives the large ring 4 to move upward, thereby driving the projector 9 to move upward to project the image outside the transparent cover 2. When it is necessary to adjust the projection angle of the image, the staff rotates the adjustment rod 17. While the adjustment rod 17 rotates, it will move downward. The downward movement of the adjustment rod 17 presses the connecting plate 16 to move downward. The downward movement of the connecting plate 16 drives the sliding frame 7 to slide downward, thereby driving the projector 9 to tilt and change the projection angle. When it is necessary to restore normal projection, control the adjustment rod 17 to reverse and move upward. After the adjustment rod 17 reverses and moves upward, it no longer presses the connecting plate 16. The sliding frame 7 then slides upward to reset and control the projector 9 to reset to a horizontal state. Then control the top cover 18 to reverse and close. The reverse rotation of the top cover 18 drives the contact block 20 to close with the contact button 19. The contact button 19 controls the output shaft of the second motor 14 to reverse through the controller, thereby driving the threaded rod 15 to reverse. The reverse rotation of the threaded rod 15 drives the large ring 4 to move downward, thereby driving the projector 9 to move downward to reset. In this way, the projection position and angle of the projector 9 can be adjusted.

[0033] As Figure 1 and Figure 6As shown in the figure, the disconnecting component includes a sliding rod 21, a second spring 22, an extrusion block 23, a mounting ring 24, an extrusion plate 25, and a contact rod 26. The middle part of the transparent cover 2 is slidably connected with symmetric left and right sliding rods 21. A second spring 22 is connected between the sliding rod 21 and the transparent cover 2. The inner end of the sliding rod 21 is fixedly connected with an extrusion block 23. The extrusion block 23 is oval-shaped and is used to extrude the mounting plate 12 away from the large ring 4. The upper side of the mounting cylinder 1 is slidably connected with a mounting ring 24. The surface of the mounting ring 24 is provided with convex blocks evenly distributed in a circumferential manner. The lower side of the mounting ring 24 is fixedly connected with two left and right extrusion plates 25. The outer end of the sliding rod 21 is fixedly connected with a contact rod 26. One side of the extrusion plate 25 close to the contact rod 26 is inclined, and the extrusion plate 25 is in extrusion fit with the adjacent contact rod 26.

[0034] When the threaded rod 15 rotates to drive the large ring 4 to move upward, the mounting plate 12 and the spring telescopic rod 11 will also move upward together with the large ring 4. When it is necessary to control the projector 9 to stop rotating, the mounting ring 24 is pushed to rotate. The rotation of the mounting ring 24 drives the extrusion plate 25 to rotate. The rotation of the extrusion plate 25 squeezes the contact rod 26 to move inward. The inward movement of the contact rod 26 drives the sliding rod 21 to slide inward. The second spring 22 deforms. The inward sliding of the sliding rod 21 drives the extrusion block 23 to move inward. The inward movement of the extrusion block 23 squeezes the mounting plate 12 to move downward. The spring telescopic rod 11 extends. The downward movement of the mounting plate 12 drives the first motor 13 to move downward and separate from the connecting shaft 10, and the projector 9 can stop rotating. When it is necessary to control the projector 9 to resume rotation, the mounting ring 24 is released. Under the action of the reset of the second spring 22, the sliding rod 21 drives the extrusion block 23 to move outward and no longer squeeze the mounting plate 12. The shortening of the spring telescopic rod 11 can drive the mounting plate 12 and the first motor 13 to move upward. After the first motor 13 moves upward and resets, it is docked with the connecting shaft 10, and the projector 9 can continue to rotate.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, it further includes a cleaning component for cleaning the transparent cover 2. The cleaning component includes a push plate 27, a rotating rod 28, a folding plate 29, a first torsion spring 291, a second torsion spring 292, a cylinder 30 and a cleaning ring 31. A push plate 27 is fixedly connected to the output shaft of the second motor 14. A rotating rod 28 is rotatably connected to the rear side of the transparent cover 2. The bottom end of the rotating rod 28 is fixedly connected to a folding plate 29. The folding plate 29 is in extrusion fit with the push plate 27. A first torsion spring 291 is connected between the rotating rod 28 and the transparent cover 2. A second torsion spring 292 is connected between the rotating joints at both ends of the folding plate 29. A cylinder 30 is slidably connected to the rotating rod 28. A vertical inclined groove is formed on the rotating rod 28. A spherical protrusion is provided at the bottom end of the cylinder 30. The spherical protrusion is located in the vertical inclined groove. The cylinder 30 penetrates through the middle of the transparent cover 2. A cleaning ring 31 is fixedly connected to the top end of the cylinder 30. The cleaning ring 31 is sleeved on the upper part of the transparent cover 2.

[0036] When using the device, the output shaft of the second motor 14 rotates to drive the push plate 27 to rotate. The push plate 27 rotates to squeeze the folding plate 29 to rotate. The folding plate 29 rotates to drive the rotating rod 28 to rotate, and the first torsion spring 291 deforms. The rotating rod 28 rotates to drive the cylinder 30 to slide upward. The cylinder 30 slides upward to drive the cleaning ring 31 to slide upward. When the push plate 27 rotates to be separated from the folding plate 29, under the action of the reset of the first torsion spring 291, the rotating rod 28 rotates in the reverse direction to drive the cylinder 30 to slide downward. The cylinder 30 slides downward to drive the cleaning ring 31 to slide downward and reset. When the push plate 27 rotates to contact the folding plate 29 again, repeating the above actions can control the cleaning ring 31 to slide up and down to clean the transparent cover 2, ensuring that the transparent cover 2 is clean and transparent and avoiding affecting the viewing effect. When the output shaft of the second motor 14 rotates in the reverse direction to drive the push plate 27 to rotate, under the action of the second torsion spring 292, the folding plate 29 can be bent to be separated from the push plate 27.
