[0045] See also Figure 1-2 As shown, a rotatable art exhibit display rack comprises:

[0046] A rotating base structure 4, wherein a rectangular support column 3 is fixedly connected to the upper surface of the rotating base structure 4, and the rotating base structure 4 can rotate to drive the rectangular support column 3 to rotate;

[0047] A placement platform 1, wherein the placement platform 1 is fixedly arranged at the top end of a rectangular support column 3;

[0048] An auxiliary fixing component 2, wherein the auxiliary fixing component 2 is arranged on the placement platform 1, and the auxiliary fixing component 2 can fix the placed artwork;

[0049] A lifting component 5, which is arranged on the rectangular support column 3, and can be folded and unfolded, and can be automatically unfolded when the artwork falls;

[0050] The nozzle 7 is arranged at the side of the placement platform 1.

[0051] Through the above technical scheme, the rotating base structure 4 can drive the artwork to rotate and display, thereby achieving a better display effect. Further, in order to avoid the instability of the artwork during the rotation process, the present application designs an auxiliary fixing component 2, through which the artwork can be effectively fixed, which is convenient for fixing artworks of different shapes, and does not hinder the normal viewing of the artwork, and the use effect is good. In order to solve the problem in the prior art that ordinary display racks are damaged and broken after the artwork falls due to accidents, the present application further designs a lifting component 5, through which the lifting component 5 can be automatically and quickly unfolded after the artwork falls, thereby playing a certain lifting function, reducing damage, and protecting the artwork, which is particularly suitable for rotating display. At the same time, the present application can automatically clean the surface of the artwork during the rotating display, reduce dust adhesion, and reduce the trouble of manual wiping, which is suitable for long-term exhibition.

[0052] For further technical solutions, see Figure 3 and Figure 4 As shown, the auxiliary fixing assembly 2 includes a fixing plate 201, a support rod 202, a positioning rod 203, a movable sleeve rod 204, a circular plate 205, a compression spring 206 and a fixing soft belt 208. The fixing plate 201 is fixedly arranged at the top of the rectangular support column 3. The four corners of the upper surface of the fixing plate 201 are fixedly connected with the support rod 202. The upper end of the support rod 202 is fixedly connected to the bottom surface of the placement platform 1. Through this technical solution, the artwork to be displayed can be placed on the upper surface of the placement platform 1 for display;

[0053] A positioning rod 203 is fixedly connected to the bottom surface of the placement platform 1, and the movable sleeve rod 204 is sleeved at the bottom end of the positioning rod 203 and slidably cooperates with the positioning rod 203. A circular plate 205 is fixedly connected to the arc surface of the movable sleeve rod 204, and one end of a compression spring 206 is fixedly connected to the upper surface of the circular plate 205. The other end of the compression spring 206 is fixedly connected to the bottom surface of the placement platform 1. According to the technical solution, the circular plate 205 can be driven to move upward by moving the movable sleeve rod 204 upward, thereby compressing the compression spring 206, so that the compression spring 206 is in a compressed state;

[0054] A cross-shaped fixing frame 207 is fixedly connected to the arc-shaped wall of the movable sleeve rod 204 , and four ends of the cross-shaped fixing frame 207 are fixedly connected to fixing soft belts 208 . The fixing soft belts 208 penetrate the placement platform 1 and are slidably matched with the placement platform 1 . The fixed soft belt 208 is made of transparent material. Through the present technical solution, when it is necessary to fix the artwork placed on the upper surface of the placement platform 1, the movable sleeve rod 204 is manually moved upward first, so that the upward movement of the movable sleeve rod 204 can drive the cross-shaped fixing frame 207 to move upward. Due to the upward movement of the cross-shaped fixing frame 207, the fixed soft belt 208 at the position above the placement platform 1 can be in a relaxed state, and then the relaxed fixed soft belt 208 can be set on the surface of the artwork by bundling or covering, and then the movable sleeve rod 204 is loosened. Since the compression spring 206 is in a compressed state, there will be a downward pressure on the movable sleeve rod 204, so that the fixed soft belt 208 is tightened to fully fix the artwork. The present application adopts the fixed soft belt 208 for fixing. Compared with the ordinary clamping and fixing structure, the present application can effectively fix artworks of different shapes, and the fixing is convenient. The fixed soft belt 208 basically does not hinder the observer from viewing and appreciating the artwork. At the same time, the auxiliary fixing component 2 can effectively and stably fix the artwork. When the device rotates, it drives the artwork to rotate and display, thereby preventing the artwork from slipping due to the centrifugal force of rotation.

[0055] For specific technical solutions, please refer to Figure 5 Figure 6 and Figure 7 As shown, the lifting assembly 5 includes a moving slider 501, a connecting leg A 502, a support frame 503, a connecting leg B 504, a lifting frame 505, a connecting leg C 506, a lifting support cloth 507 and a connecting sleeve rod 508. The interior of the rectangular support column 3 is provided with an inner cavity, and the moving slider 501 is arranged in the inner cavity of the rectangular support column 3 and is slidably matched with the rectangular support column 3;

[0056] There are four connecting legs B504, which are respectively fixed on the four side walls of the rectangular support column 3. The connecting legs B504 are rotatably connected to the lifting frame 505, and the upper surface of the lifting frame 505 is fixedly connected to the connecting legs C506. One end of the support frame 503 is rotatably connected to the connecting legs C506, and the other end of the support frame 503 is rotatably connected to the connecting legs A502. The connecting legs A502 is fixedly connected to the side wall of the movable slider 501, and the lifting frames 505 are fixedly connected to the lifting support cloth 506. 7. A connecting rod 509 is fixedly connected to the upper surface of the movable slider 501. A connecting rod 508 is slidably connected to the connecting rod 509. The top of the connecting rod 508 is fixedly connected to the bottom end of the movable rod 204. One end of a connecting spring 510 is fixedly connected to the top of the connecting rod 509. The other end of the connecting spring 510 is fixedly connected to the upper wall of the inner cavity of the connecting rod 508. Through the technical solution, when the auxiliary fixing component 2 fixes the artwork, the movable rod 204 will move upward, and the upward movement of the movable rod 204 will drive the movable slider 501 to move upward, so that Figure 6 As shown, the lifting assembly 5 is in a folded state. The lifting assembly 5 in the folded state occupies a small area and does not hinder viewers from viewing the artwork at close range. When the artwork accidentally falls, the artwork loosens from the fixed soft belt 208 and falls, and the fixed soft belt 208 loses the supporting function of the artwork itself, so that the compression spring 206 in the compressed state rebounds quickly, pushing the moving sleeve rod 204 to move downward. The downward movement of the moving sleeve rod 204 pushes the moving slider 501 to move downward. The downward movement of the moving slider 501 drives the support frame 503 to rotate angularly, thereby driving the lifting skeleton 505 to rotate angularly, so that the lifting skeleton 505 moves to a horizontal state, and the lifting support cloth 507 is unfolded. It can be seen from the above description that at the moment when the artwork loosens and falls, the lifting assembly 5 can be automatically unfolded, so that the lifting support cloth 507 can be unfolded to support the fallen artwork, reduce the impact damage caused by falling, and play the function of automatically protecting the fallen artwork.

[0057] The side wall of the movable slider 501 is threadedly connected with a locking bolt 511. Through the technical solution, when the device is not in use, the movable slider 501 can be moved upward by manually moving the movable sleeve 204, so that the lifting frame 505 is folded up, and the locking bolt 511 is tightened at the same time, so that the locking bolt 511 is pressed against the side wall of the rectangular support column 3, thereby locking and fixing the movable slider 501, which is convenient for carrying and other work. When in use, the locking bolt 511 is loosened to unlock the movable slider 501.

[0058] For specific technical solutions, please refer to Figure 8 , Fig. 9 and Fig.10 As shown, the rotating base structure 4 includes a fixed base 401, a rotating disk 402, a servo motor 403, an annular frame 404 and a gas output part. The rotating disk 402 is rotatably connected to the upper surface of the fixed base 401. The servo motor 403 is fixedly installed in the inner cavity of the fixed base 401. The end of the output shaft of the servo motor 403 is fixedly connected to the bottom surface of the rotating disk 402. The annular frame 404 is fixedly arranged on the arc surface of the fixed base 401. The rectangular support column 3 is fixedly arranged on the upper surface of the rotating disk 402. Through the technical solution, the rotating disk 402 can be driven to rotate by the operation of the servo motor 403, so that the rectangular support column 3 can be driven to rotate by the rotation of the rotating disk 402, thereby driving the placement platform 1 to rotate, thereby realizing the rotating display function of the artwork;

[0059] The gas output part includes a tripod 405, a pressure plate 406, a rubber airbag 407 and a protrusion 411, wherein a plurality of protrusions 411 are provided, and a plurality of the protrusions 411 are equidistantly fixed on the arc-shaped wall of the rotating disk 402, a plurality of tripods 405 are provided, and a plurality of the tripods 405 are equidistantly fixed on the arc-shaped inner wall of the annular frame 404, a pressure plate 406 is rotatably connected to the tripod 405, one end of the rubber airbag 407 is fixedly connected to the side wall of the pressure plate 406, and the other end of the rubber airbag 407 is fixedly connected to the inner wall of the annular frame 404, a return spring 408 is fixedly connected between the upper and lower side walls of the inner cavity of the rubber airbag 407, an output hose 409 is fixedly connected to the inner cavity of the rubber airbag 407, an output one-way valve is installed on the output hose 409, and a return spring 408 is fixedly connected to the upper and lower side walls of the inner cavity of the rubber airbag 407, an output hose 409 is fixedly connected to the inner cavity of the rubber airbag 407, an output one-way valve is installed on the output hose 409, and a return spring 408 is fixedly connected to the upper and lower side walls of the inner cavity of the rubber airbag 407, and an output hose 409 is fixedly connected to the output one-way valve. An input pipe 410 is installed, and an input non-return valve is installed on the input pipe 410. According to the technical solution, when the rotating disk 402 rotates, the protrusion 411 can be driven to rotate, and then the protrusion 411 can contact with the pressing plate 406 through the rotation, and squeeze the pressing plate 406, so that the pressing plate 406 is rotated angularly, thereby squeezing the rubber airbag 407. Since the rubber airbag 407 is squeezed, the gas in the inner cavity of the rubber airbag 407 is squeezed and output through the output hose 409. After the squeezing is completed, the rubber airbag 407 is reset and propped up due to the setting of the reset spring 408, so that the gas is sucked through the input pipe 410 through the propping up of the rubber airbag 407. According to the technical solution, during the continuous rotation of the rotating disk 402, the output hose 409 can automatically output gas;

[0060] The nozzle 7 is fixedly arranged at one end of the connecting bracket 6, and the connecting bracket 6 is fixedly arranged at the side position of the placement platform 1. The input port of the nozzle 7 is fixedly connected with a connecting pipe 8, and the connecting pipe 8 is connected to the output hose 409. Through the present technical solution, when the artwork is rotated for display, the output hose 409 automatically outputs gas, so that the gas is transported to the nozzle 7 for spraying. The sprayed gas can spray and clean the artwork fixed on the upper surface of the placement platform 1, and automatically blow and clean the dust attached to the surface. Through the present technical solution, the artwork can be automatically blown and cleaned when it is rotated for display. At the same time, there is no need to use additional electrical equipment such as fans, thereby reducing the labor intensity of manual wiping. It is particularly suitable for artworks that need to be exhibited for a long time.
