Description

Technical Field

[0001] The present invention belongs to the technical field of artwork display, and in particular relates to a visual communication device for artwork display. Background Art

[0002] After a work of art is designed and manufactured, if it needs to be displayed, it is generally placed in a display stand for display. In order to achieve a better display effect, a display stand generally only displays one work of art. However, for better display, artworks of various styles are usually placed in a display stand for display. However, when displaying different styles of artworks on the same display stand, the platform cannot shoot and display the exhibits in all directions, resulting in the inability to fully display the details of the exhibits to the viewer. In addition, when the existing devices are displayed, the exhibits are fixed, so the devices need to be fixed in a wide place, wasting a lot of placement space, and the materials used for some precious exhibits will be oxidized to a certain extent, resulting in certain damage to the exhibits when they are on display, which is not suitable for long-term display. Summary of the invention

[0030] The working principle of the above technical solution is as follows:

[0031] An exhaust pipe 6 is fixedly installed at one end of the oxygen pump 5, and the exhaust pipe 6 is inserted out of the outside of the cabinet 1. An air intake pipe 7 is fixedly installed at the other end of the oxygen pump 5, and the air intake pipe 7 is inserted out of the top of the cabinet 1. When the device displays exhibits with oxidizing characteristics, the glass cover 26 is inserted into the rectangular ring groove 27 to form a closed space. The oxygen pump 5 extracts the air in the closed space through the air intake pipe 7 to achieve a vacuum state to prevent the exhibits from oxidizing.

The slider 18 slides inside the slide groove 39, so that when the slider 18 is installed with the linked parts to rise and fall, the slider 18 limits the device.

[0032] In another embodiment, Figure 1-5 As shown, the threaded rotating column 32 is meshed with the rotating column 21, so that the rotation of the threaded rotating column 32 drives the rotating column 21 to rotate at the same time, and then the storage tray 24 rotates accordingly, so that when the storage tray 24 is placed on the exhibit for display, the exhibit can be rotated 360 degrees through the rotation of the storage tray 24, so that when several viewing surfaces of the device are blocked, the exhibit can also be seen from all directions.

[0033] In another embodiment, Figure 1-5 As shown, when the device rises to display exhibits, the round block 23 is inserted into the slot 29, so that the display hole 28 is blocked, so that the device can better realize a closed space and a vacuum state when displaying exhibits with oxidizing characteristics.

[0034] In another embodiment, Figure 1-5 As shown, four cameras 25 are fixedly mounted on the top of the cabinet 1, which are installed at four corners, so that the exhibits can be photographed in all directions and transmitted to the display, thereby preventing the situation where the exhibits are not fully photographed.

[0035] The working principle and use process of the present invention are as follows: an exhaust pipe 6 is fixedly installed at one end of the oxygen pump 5, and the exhaust pipe 6 is inserted out of the outside of the cabinet 1, and an air intake pipe 7 is fixedly installed at the other end of the oxygen pump 5, and the air intake pipe 7 is inserted out of the top of the cabinet 1. When the device displays exhibits with oxidizing characteristics, the glass cover 26 is inserted into the rectangular ring groove 27 to form a closed space, and the oxygen pump 5 extracts the air in the closed space through the air intake pipe 7 to achieve a vacuum state to prevent the exhibits from oxidizing. One end of the threaded column 14 is fixedly installed with the top block 16, and the other end passes through the fixed round block 17, the first rotating shaft 13, the second bevel gear 12 and the lifting seat 8. Installed on the mounting block 3, and The fixed round block 17 is fixedly connected to the lifting seat 8 through the slider 18, so that when the device is in use, the lifting seat 8 and the parts on the lifting seat 8 rise and fall synchronously when the second bevel gear 12 rotates to rise and fall, thereby achieving the overall linkage of the device. The second bevel gear 12 and the first bevel gear 10 are meshed, so that the first bevel gear 10 provides kinetic energy to the linkage column 11, so that the second bevel gear 12 rotates to drive the linked parts to rise and fall, so that exhibits can be exhibited and replaced. The slider 18 slides inside the slide groove 39, so that when the slider 18 is installed with the linked parts to rise and fall, the slider 18 limits the device.

[0036] The threaded rotating column 32 and the rotating column 21 are meshed with each other, so that the rotation of the threaded rotating column 32 drives the rotating column 21 to rotate at the same time, and then the storage tray 24 rotates accordingly, so that when the storage tray 24 is placed on the exhibit for display, the exhibit can be rotated 360 degrees through the rotation of the storage tray 24, so that when the device is blocked from several viewing surfaces, the exhibit can also be seen from all directions. When the device rises to display the exhibit, the round card block 23 is inserted into the card slot 29, so that the exhibition hole 28 is blocked, so that when the device displays exhibits with oxidizing characteristics, it is better to realize a closed space and facilitate the realization of a vacuum state. Four cameras 25 are fixedly installed on the top of the cabinet 1, installed at four corners, so that the exhibits can be photographed in all directions and transmitted to the display, preventing the situation of incomplete photography when photographing the exhibits.

[0037] When the device is in use, the glass cover 26 is inserted into the rectangular ring groove 27, and then the cabinet door 2 is opened, and the exhibits are placed on the storage tray 24.

The double-disc round block 38 is connected to the connecting column 36 on the turntable 35 through the linkage block 37 installed movably inside, and rotates in linkage, and then drives the two linkage columns 11 to rotate, and the first bevel gear 10 installed at one end of the linkage column 11 rotates accordingly. The rotation of the first bevel gear 10 drives the second bevel gear 12 with teeth and teeth to rotate and rise on the surface of the threaded column 14. When the second bevel gear 12 rises, At the same time, the first rotating shaft 13, the fixed round block 17, the sliding block 18, and the lifting seat 8 are driven to rise together, and then the storage tray 24 rises from the exhibition hole 28 to the inside of the glass cover 26, and the round clamping block 23 is clamped into the inside of the clamping groove 29 to realize a closed space, and then the first motor 31 is started, and the threaded rotating column 32 starts to rotate, and at the same time drives the gear and the rotating column 21 to rotate synchronously, and the storage tray 24 is driven by the rotation of the rotating column 21 to rotate and display the exhibits, and then the oxygen extraction pump 5 is started, and the air inside the glass cover 26 is sucked out through the suction pipe 7 and discharged from the exhaust pipe 6, so as to realize the vacuum state inside the glass cover 26.
