Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] As attached Figure 1-Figure 7 The art exhibition lighting auxiliary device shown includes a base 1, on which a rotating component 2 is installed, a protective tube 3 is provided on one side of the base 1, a lifting component 4 is installed in the protective tube 3, a protective component 5 is inserted at the top of the protective tube 3, an adjusting component 6 is installed on the lifting component 4, and a lamp body 7 is installed on the adjusting component 6.
[0033] During specific implementation, the base 1 is used as the supporting foundation of the entire device, the rotating component 2 realizes the rotation of the exhibition stand 203, the protective tube 3 provides a protective space, the lifting component 4 adjusts the height of the lamp body 7, the protective component 5 protects the internal components, the adjustment component 6 adjusts the angle of the lamp body 7, and the lamp body 7 provides lighting. The components cooperate with each other to meet the lighting auxiliary needs of the artwork exhibition. The overall structural design is reasonable, and the division of labor of each component is clear. It can realize multi-angle and multi-dimensional adjustment of the artwork exhibition lighting, improve the exhibition effect, and at the same time play a certain protective role for the internal components.
[0034] Specifically, the base 1 stably supports other components, the rotating component 2 drives the exhibition stand 203 to rotate, so that the artwork can be displayed in all directions, the protective tube 3 provides a protective space for the internal components, and the lifting component 4 adjusts the height of the lamp body 7 as needed to adapt to different exhibits; the protective component 5 plays a protective role when the device is not in use or under maintenance, and the adjustment component 6 cooperates with the lamp body 7 to achieve precise adjustment of the light angle, ensuring that the light can illuminate the artwork with the best effect, thereby enhancing the viewing and professionalism of the exhibition.
[0035] The rotating component 2 includes a first motor 201, a rotating rod 202, an exhibition stand 203 and a ball 204. The first motor 201 drives the rotating rod 202 to rotate, and the rotating rod 202 drives the exhibition stand 203 to rotate. A plurality of ball grooves are provided at the bottom of the exhibition stand 203, and the plurality of ball grooves are arranged in a ring shape, and a ball 204 is provided in each ball groove.
[0036] During specific implementation, the first motor 201 provides power to drive the rotating rod 202 to rotate, and the rotating rod 202 drives the exhibition stand 203 to rotate. The ball bearings 204 in the ball grooves at the bottom of the exhibition stand 203 reduce the rotation friction, so that the exhibition stand 203 rotates more smoothly, and the exhibition stand 203 can rotate stably and smoothly, displaying artworks at multiple angles, improving the viewing experience of the audience, and the setting of the ball bearings 204 reduces the friction during rotation, reduces the wear of components, and prolongs the service life of the device;
[0037] Specifically, the first motor 201, the rotating rod 202, the exhibition stand 203 and the ball bearing 204 work together. When the first motor 201 is powered on, its output shaft drives the rotating rod 202 to rotate, and the rotating rod 202 drives the exhibition stand 203 to rotate synchronously. The ball bearing 204 rolls between the exhibition stand 203 and the base 1 to reduce contact friction, making the rotation of the exhibition stand 203 more stable and easy, which can better meet the needs of multi-angle display of artworks.
[0038] A partition is provided at the top of the interior of the base 1 , the first motor 201 is installed at the bottom of the partition, the rotating rod 202 is rotatably connected to the partition, and an arc groove cooperating with each ball 204 is opened at the top of the partition.
[0039] In specific implementation, the partition at the top of the base 1 is used to install the first motor 201 and support the rotating rod 202. The arc groove at the top of the partition cooperates with the ball 204 to further stabilize the rotation of the exhibition stand 203. The setting of the partition makes the first motor 201 more firmly installed, and the arc groove cooperates with the ball 204 to enhance the stability of the exhibition stand 203 during rotation, thereby preventing the exhibition stand 203 from shaking and ensuring the display effect of artworks.
[0040] Specifically, the partition fixes the first motor 201 at a suitable position inside the base 1, and the rotating rod 202 is rotatably connected to the partition to ensure the stability of the rotation of the rotating rod 202. The ball 204 at the bottom of the exhibition stand 203 rolls in the arc groove, limiting the radial displacement of the exhibition stand 203, making the exhibition stand 203 more stable during rotation, reducing vibration, and providing a stable platform for art display.
[0041] The lifting assembly 4 includes a second motor 401, a screw rod 402, a guide rod 403, a lifting slider 404 and a support frame 405. The second motor 401 drives the screw rod 402 to rotate.

The screw rod 402 drives the lifting slider 404 to rise and fall along the guide rod 403. The lifting slider 404 is connected to the support frame 405, and an adjustment assembly 6 is provided on the support frame 405.
[0042] In specific implementation, after the second motor 401 is powered on, its output shaft drives the screw rod 402 to rotate, and the threads on the screw rod 402 interact with the threads of the lifting slider 404, so that the lifting slider 404 moves axially on the screw rod 402. Since the guide rod 403 and the lifting slider 404 slide together, the rotation of the lifting slider 404 is limited, ensuring that the lifting slider 404 can only move up and down along the guide rod 403, thereby realizing the precise adjustment of the height of the lamp body 7 and meeting the requirements of different exhibits on the light height.
[0043] The inner wall of the protection tube 3 is provided with a slot 8 , and the protection component 5 is plugged into and matched with the slot 8 .
[0044] In specific implementation, when installing the protection component 5, the protection plug plate 502 is aligned with the slot 8 on the inner wall of the protection tube 3 and inserted to complete the installation of the protection component 5. The operation is simple and convenient. The slot 8 positions and fixes the protection plug plate 502, so that the protection component 5 remains stable during use, and effectively protects the lifting component 4 and other components in the protection tube 3 from external dust, water vapor, etc.
[0045] The protection assembly 5 includes a top cover 501 and a protection plug plate 502 . The top cover 501 is installed on the top of the protection tube 3 . Two protection plug plates 502 are provided. Each protection plug plate 502 is plugged into and matched with a corresponding slot 8 .
[0046] In specific implementation, the top cover 501 is installed on the top of the protective tube 3 to block the dust and debris on the top; the two protective plug plates 502 are respectively inserted into the slots 8 to protect the internal components from the side, which can fully protect the components in the protective tube 3 to prevent dust and debris from entering, thereby extending the service life of the device without affecting the normal operation of the device;
[0047] Specifically, the top cover 501 covers the top of the protective tube 3 to block dust, debris, etc. falling from above. After the two protective plug plates 502 are inserted into the slot 8, the sides of the protective tube 3 are closed, and together with the top cover 501, a relatively closed protective space is formed to protect the internal components such as the lifting component 4 and the adjustment component 6, reduce the impact of external factors on its performance, and ensure the long-term stable operation of the device.
[0048] The adjustment component 6 includes a first electric push rod 601, a fixed frame 602, a second electric push rod 603, a slide rail 604 and an angle adjustment slider 605. The first electric push rod 601 is installed on the support frame 405, and the fixed frame 602 is installed on the top of the support frame 405. The second electric push rod 603 is installed on the fixed frame 602. The first electric push rod 601 is hinged to one end of the lamp body 7, the slide rail 604 is fixed on the lamp body 7, and the angle adjustment slider 605 is slidably connected to the slide rail 604.
[0049] In specific implementation, the first electric push rod 601 is installed on the support frame 405, and pushes one end of the lamp body 7 to change its position by telescoping; the second electric push rod 603 is installed on the fixed frame 602, and drives the angle adjustment slider 605 to slide on the slide rail 604, thereby adjusting the angle of the lamp body 7, which can flexibly and accurately adjust the angle of the lamp body 7 to meet the diverse requirements of different artworks on the lighting angle, and improve the lighting effect of the exhibition;
[0050] Specifically, when the angle of the lamp body 7 needs to be adjusted, the first electric push rod 601 is started, and its telescopic end pushes one end of the lamp body 7 to move, thereby changing the initial position of the lamp body 7; at the same time, the second electric push rod 603 is started, and the telescopic movement of the second electric push rod 603 drives the angle adjustment slider 605 to slide on the slide rail 604. Since the angle adjustment slider 605 is connected to the lamp body 7, the angle of the lamp body 7 can be accurately adjusted, so that the light can illuminate the artwork at the best angle, highlighting the characteristics and beauty of the artwork.
[0051] The first motor 201 is a forward and reverse motor, and is used to control the exhibition stand 203 to rotate clockwise or counterclockwise.
[0052] In specific implementation, during the exhibition, according to the exhibition requirements and the audience's viewing habits, the first motor 201 is controlled to rotate forward or reverse. When the first motor 201 rotates forward, the rotating rod 202 drives the exhibition stand 203 to rotate clockwise. When the first motor 201 rotates reversely, the rotating rod 202 drives the exhibition stand 203 to rotate counterclockwise, so that the audience can view the artworks from different directions, increasing the interest and attraction of the exhibition.
[0053] The surface of the exhibition stand 203 is provided with an anti-skid layer to prevent exhibits from sliding.
[0054] In specific implementation, when the exhibition stand 203 rotates, the anti-skid layer contacts the bottom of the exhibit, and the increased friction can effectively prevent the exhibit from sliding due to the centrifugal force generated by the rotation, ensuring that the exhibit remains in a fixed position on the exhibition stand 203, avoiding the exhibit from falling and being damaged, and ensuring the smooth progress of the exhibition.
[0055] The bottom of the base 1 is provided with an anti-skid pad to increase the stability of the device.
[0056] In specific implementation, during the use of the device, the anti-skid pad is in close contact with the ground, and the increased friction enables the base 1 to be stably fixed on the ground. Even if the floor of the exhibition venue is uneven or there is a slight vibration, the anti-skid pad can effectively prevent the base 1 from sliding or shaking, ensuring the normal operation of components such as the rotating assembly 2 and the lifting assembly 4, and providing a stable basic support for the art exhibition.
[0057] During specific use, the base 1 is placed at a suitable position in the exhibition venue, ensuring that the anti-slip pad at the bottom of the base 1 is in full contact with the ground to increase the stability of the device placement, and the first motor 201 is installed at the bottom of the partition at the top inside the base 1. The rotating rod 202 passes through the partition and is rotatably connected thereto, and the ball 204 is placed in the ball groove at the bottom of the exhibition stand 203. The exhibition stand 203 is installed on the rotating rod 202 through the ball 204 and the arc groove at the top of the base 1 to complete the installation of the rotating component 2.
[0058] A slot 8 is opened on the inner wall of the protective tube 3, and the second motor 401, the screw rod 402, and the guide rod 403 are installed in the protective tube 3, so that the screw rod 402 is threadedly matched with the lifting slider 404, and the guide rod 403 is slidingly matched with the lifting slider 404, and then the lifting slider 404 is connected to the support frame 405, the installation of the lifting assembly 4 is completed, and the protective tube 3 is installed on one side of the base 1.
[0059] The top cover 501 is installed on the top of the protection tube 3 , and the two protection plug plates 502 are respectively inserted into the corresponding slots 8 on the inner wall of the protection tube 3 to complete the installation of the protection assembly 5 .

[0061] When it is necessary to exhibit artworks, the artworks are placed on the exhibition stand 203, and the first motor 201 is started. The first motor 201 drives the rotating rod 202 to rotate, thereby driving the exhibition stand 203 to rotate, so that the artworks can be displayed at multiple angles. According to the height of the artworks and the exhibition requirements, the second motor 401 is started. The second motor 401 drives the screw rod 402 to rotate, and the screw rod 402 drives the lifting slider 404 to rise and fall along the guide rod 403, so as to adjust the height of the lamp body 7. By controlling the first electric push rod 601 and the second electric push rod 603, the first electric push rod 601 pushes one end of the lamp body 7 to change its position, and the second electric push rod 603 drives the angle adjustment slider 605 to slide on the slide rail 604, so as to adjust the angle of the lamp body 7, so that the light can illuminate the artwork at the best angle.
