A support frame 5 of the structure is provided, and a display 7 is fixedly installed on the inner arc surface of the support frame 5, a vertically distributed electric push rod 14 is also installed on the inner arc surface of the support frame 5, and a top cover mechanism 6 is installed on the top of the electric push rod 14, a fill light 15 with an arc structure is installed inside the top cover mechanism 6, and a retractable upper protection ring mechanism 8 is also installed inside the top cover mechanism 6, a rotatable placement rack mechanism 12 is installed in the top center of the display stand 9, an air pump 17 and a three-way solenoid valve 16 which are interconnected are installed in sequence inside the base 1, and the outlet of the three-way solenoid valve 16 is connected to the upper protection ring mechanism 8 and the placement rack mechanism 12 through a pipeline.

[0031] In the present invention, a placement rack mechanism 12 is provided for fixing the bottom of the artwork. The artwork is placed inside the placement rack mechanism 12 for rotation and display, and the information of the artwork is played through the display 7, combining the physical display with the audio and video explanation. The diversified display facilitates people to understand the artistic value of the exhibits. At the same time, the device is also provided with a protective cover mechanism 4 and an upper protective ring mechanism 8. When the art exhibit needs to be transferred, the upper protective ring mechanism 8 is removed from the top cover mechanism 6, and the upper end of the art exhibit is effectively fixed. The air pump 17 and the three-way solenoid valve 16 are used to inflate the upper protective ring mechanism 8 and the placement rack mechanism 12, and a protective air bag is formed on the outside of the art exhibit to firmly hold the art exhibit. It is fixed in the middle of the device for protection and fixation. Thereafter, the protection cover mechanism 4 moves outward along the guide rail bracket 3. After the protection cover mechanism 4 is closed, a cylindrical protection shell cover is formed between the guide rail bracket 3 and the top cover mechanism 6 to protect the internal art exhibits. The movable support mechanism 2 located at the bottom of the base 1 is unfolded, and the device is synchronously supported by rollers, which is convenient for the transfer and movement of the display device carrying art exhibits. When the art exhibits are moved, there is no need to remove them for storage. Multi-layer protection prevents the exhibits from being damaged during the transfer process. When the transfer is completed, the protection cover mechanism 4 shrinks and the upper protection ring mechanism 8 and the placement rack mechanism 12 are reset. The art exhibits can quickly resume the display state after the transfer, thereby improving the convenience of the transfer.

[0032] As a further solution of the present invention, the movable support mechanism 2 includes two fixed shells 21 installed at the two end positions inside the base 1, and a transmission worm 23 rotatably installed between the two fixed shells 21. A movable motor 22 that drives the transmission worm 23 to rotate is installed inside the base 1. The two end positions of the two fixed shells 21 are rotatably installed with obliquely distributed threaded screws 25, and the ends of the threaded screws 25 are transmission-connected to the ends of the transmission worm 23.

When the movable motor 22 drives the transmission worm 23 to rotate, it synchronously drives the four inclined threaded screws 25 to rotate. The lifting bracket 24 is screwed to the outer side of the threaded screw 25, which can drive the lifting bracket 24 to expand outward along the direction of the threaded screw 25. The four corners of the device are synchronously lifted by the supporting rollers 26 at the bottom of the lifting bracket 24, so that the device can be pushed and moved. Compared with the traditional roller structure, the display process is more stable and reliable.

In the present invention, during the display stage, the electric push rod 14 is used to drive the top cover mechanism 6 to move up and down, adjust the distance between the top and the art exhibits, and cooperate with the application of the fill light 15 to change the visual effect during the display process. At the same time, when the protective cover mechanism 4 is closed, the top cover mechanism 6 provides an effective guiding effect for the top of the protective cover mechanism 4, thereby improving the protective effect of the protective cover mechanism 4.

[0034] As a further solution in the present invention, the upper protection ring mechanism 8 includes an annular tube 81 installed inside the top cover body 61, and three protection rods 82 are hinged at the bottom of the annular tube 81, and the protection rods 82 are adapted to the hidden grooves 62. The bottoms of the protection rods 82 are all installed with an upper airbag assembly with an arc structure. A connecting hose 86 is arranged between the annular tube 81 and the annular tube 81. The annular tube 81 is connected to the three-way solenoid valve 16 through a pipeline. In the present invention, the upper airbag assembly is rolled up into a ball shape during the display stage and stored in the hidden groove 62 together with the protection rods 82. When the art exhibits need to be stored, the protection rods 82 are rotated to a vertical state and locked and fixed. Then the ball-shaped upper airbag assembly is unfolded, and the ends of the three upper airbag assemblies are connected and fixed to form a ring. When gas is rushed into the upper airbag assembly, it expands to form an elastic protection ring on the outside of the art exhibit, and cooperates with the placement rack mechanism 12 to fix and protect the upper and lower ends of the art exhibits to prevent damage to the art exhibits during the transition of the device.

[0035] As a further solution in the present invention, the upper airbag assembly includes an elastic strip 84 with a C-shaped cross-section, and an upper airbag body 83 installed inside the elastic strip 84. Both ends of the elastic strip 84 and the upper airbag body 83 are provided with locking buckles 85 that are assembled and fixed to each other. In the present invention, the three elastic strips 84 and the upper airbag body 83 are connected end to end to form an annular structure. When the upper airbag body 83 is stamped inside, the elastic strip 84 is driven to deform to adapt to the shape of the art exhibit, and is fixed by the upper airbag body 83 and the surface of the art exhibit. Through cooperation with the three fixed protection rods 82, a stable support is formed at the upper end of the art exhibit, thereby avoiding damage to the art exhibit when it is fixed and protected.

[0036] As a further solution in the present invention, the placement rack mechanism 12 includes a display motor 121 installed on the top of the display stand 9, and an exhibit placement table 122 rotatably installed in the middle of the display stand 9, and the exhibit placement table 122 is fixedly installed at the output shaft position of the display motor 121. In the present invention, the art exhibits are placed on the exhibit placement table 122, and the display motor 121 can drive the art exhibits to rotate for display.

An annular airbag 124 is installed inside the annular bracket 125, and the annular airbag 124 is connected to the three-way solenoid valve 16 through a pipeline. In the present invention, when the art exhibit is placed on the exhibition stand 122, compressed air is rushed into the annular airbag 124. When the annular airbag 124 expands, it extends outward from the inner side of the guide portion 123 to firmly wrap the base of the art exhibit, completing the fixing operation of the bottom of the art exhibit. When it is necessary to transfer the display, the upper protective ring mechanism 8 located at the upper end can be used to achieve the wrapping protection of the art exhibit.

[0038] As a further solution of the present invention, the protective cover mechanism 4 includes an outer protective plate 46, a middle protective plate 45 and an inner protective plate 43 which are slidably mounted on the guide rail bracket 3 in sequence, and the outer arc surfaces of the middle protective plate 45 and the inner protective plate 43 are both provided with arc-shaped card slots 47, and the inner arc surfaces of the outer protective plate 46 and the middle protective plate 45 are both provided with linkage blocks 48 which slide with the arc-shaped card slots 47, and the inner side of the inner protective plate 43 is provided with a protrusion 44 which snaps with the edge of the support frame 5, and the protective cover mechanism 4 also includes a driving mechanism for driving the outer protective plate 46 The sliding drive assembly is installed at the bottom of the display stand 9. In the present invention, the drive assembly drives the outer protective plate 46 to move outward along the guide rail bracket 3, and through the cooperation of the arc-shaped slot 47 and the linkage block 48, it drives the middle protective plate 45 and the inner protective plate 43 to move outward in turn. The outer protective plate 46, the middle protective plate 45, the inner protective plate 43 and the support frame 5 form a cylindrical protective cover surrounding the outside of the art exhibit, which protects the art exhibit on the inside and effectively prevents the art exhibit from being damaged during the transition process.

[0039] As a further solution in the present invention, the driving assembly includes two driving rings 41 rotatably installed at the bottom of the display stand 9, and two driving motors 42 installed at the top of the base 1, and the two driving motors 42 are respectively engaged with the two driving rings 41 for transmission, and the side of the driving ring 41 is provided with a driving rod rotatably connected to the bottom of the outer protective plate 46. In the present invention, the two driving motors 42 respectively drive the two driving rings 41 to rotate in the opposite direction, and then drive the outer protective plates 46 on both sides to move synchronously outward, completing the deployment movement of the outer protective plate 46, the middle protective plate 45 and the inner protective plate 43 in sequence.

[0040] As a further solution in the present invention, the shielding mechanism 10 includes a main torsion spring shaft 102 installed in the installation groove 13, and the rotating end of the main torsion spring shaft 102 is installed with a spring rod 101, the outer end of the spring rod 101 is installed with a secondary torsion spring shaft 103, and the rotating end of the secondary torsion spring shaft 103 is installed with a plurality of mutually hinged arc shielding plates 105, and the inner side of the arc shielding plate 105 is provided with a limiting arc plate 104 that matches the notch of the installation groove 13.

Under the action, the outward thrust is maintained, and the outer side of the arc shielding plate 105 effectively blocks the edge of the guide rail bracket 3 through the limiting cooperation between the limiting arc plate 104 and the notch of the installation groove 13, so as to keep the display table of the display device beautiful. When the outer protective plate 46 moves outward, the outer protective plate 46 first pushes the arc shielding plate 105 at the end to retract into the inside of the installation groove 13, and then pulls the arc shielding plate 105 at the other end inward in turn through the arc shielding plate 105 at the outer end, until the main torsion spring shaft 102, the spring rod 101 and the auxiliary torsion spring shaft 103 rotate to store energy, and pushes all the arc shielding plates 105 into the inside of the installation groove 13.

[0041] When in use, the artwork is placed inside the placement rack mechanism 12 for rotational display, and the information on the artwork is played through the display 7, combining the physical display with the audio and video explanation, and the diversified display facilitates people to understand the artistic value of the exhibits. At the same time, the device is also provided with a protective cover mechanism 4 and an upper protective ring mechanism 8. When the art exhibit needs to be transferred, the upper protective ring mechanism 8 is removed from the top cover mechanism 6, and the upper end of the art exhibit is effectively fixed, and the air pump 17 and the three-way solenoid valve 16 are used to inflate the upper protective ring mechanism 8 and the placement rack mechanism 12, so as to form a protective airbag on the outside of the art exhibit, so that the art exhibit is firmly fixed in the device. The middle part is protected and fixed, and then the protection cover mechanism 4 moves outward along the guide rail bracket 3. After the protection cover mechanism 4 is closed, a cylindrical protection shell cover is formed between the guide rail bracket 3 and the top cover mechanism 6 to protect the internal art exhibits. The movable support mechanism 2 located at the bottom of the base 1 is unfolded, and the device is synchronously supported by rollers, which is convenient for the transfer and movement of the display device carrying art exhibits.
