Description

Technical Field

[0001] The utility model relates to the field of publicity devices, in particular to a publicity column. Background Art

[0002] Propaganda columns are an effective means for organizations or enterprises to conduct self-promotion. As an important display tool, propaganda columns are often used in public places such as streets, factories, and hotels. They generally use stainless steel as frames, tempered glass or endurance boards as panels, and aluminum alloy as ceilings. The panels can be opened to replace promotional images.

[0003] Traditional billboards usually adopt a fixed display method. The display content is not easy to change, and the display surface is limited, which makes it difficult to meet the diverse publicity needs. In addition, most billboards still have problems such as inconvenient operation and limited display effect. The opening and closing of the display window also requires the use of special tools, which increases the difficulty and cost of use. For this reason, we proposed a billboard. Utility Model Content

[0028] Display devices 5, which are three in number and are arranged on three sides of the conical mounting body 4, and are used to post display contents;

[0029] The interval rotation device 12 is arranged in the upper layer of the inner cavity of the underground device box 1 and is used to provide interval rotation force for the conical installation body 4.

[0030] Furthermore, the interval rotation device 12 includes a rotating disk 8, a follower disk 9, a rotating shaft 10 and a limiting column 11. The rotating shaft of the driving motor 7 extends to the upper surface of the mounting plate 6 and is fixedly connected to the rotating shaft 10. The follower disk 9 is fixedly connected to the rotating shaft 10. The lower end of the rotating rod 3 extends into the inner cavity of the buried device box 1 and is rotatably connected to the upper surface of the mounting plate 6 away from the follower disk 9. The lower end of the rotating rod 3 is fixedly connected to the rotating disk 8. The outer ring of the upper surface of the follower disk 9 is fixedly connected to the limiting column 11.

[0031] Furthermore, the rotating disk 8 is in a cross shape, the protruding parts of the cross are pointers, and the four pointers are all provided with inwardly recessed toggle grooves.

[0032] Furthermore, the display device 5 includes a protective window 14 and a magnetic plate 19 . The protective window 14 is hinged on the front side of the display column 13 , and the magnetic plate 19 is fixedly connected to the inner wall of the display column 13 .

[0033] Furthermore, the side of the magnetic plate 19 away from the display column 13 is coated with an antistatic coating.

[0034] Furthermore, the display device 5 also includes an insert block 15, a slot 16, a threaded ring 17 and a threaded fixing rod 18. Two symmetrically arranged slots 16 are provided at both ends of the bottom inner wall of the display column 13. Two insert blocks 15 are fixedly connected to the lower end of the inner side surface of the protective window 14. The two insert blocks 15 are movably inserted in the slots 16. Two threaded rings 17 are fixedly inserted below the lower surface of the display column 13 corresponding to the slots 16. The threaded fixing rod 18 is threadedly connected in the threaded ring 17.

[0035] Furthermore, the length of the threaded fixing rod 18 is the distance from the bottom inner wall to the lower surface of the display column 13 , the upper end of the threaded fixing rod 18 is threadedly connected to the insert block 15 , and a cross groove is formed on the lower surface of the threaded fixing rod 18 .

[0036] Working principle: When installing the device, it is only necessary to bury the underground device box 1 in the ground so that the rotating sleeve 2 is exposed on the surface. When the display content in the display device 5 needs to be replaced, the operator only needs to rotate the threaded fixing rod 18, rotate the upper end of the threaded fixing rod 18 out of the plug block 15, and then lift the protective window 14 to open the display column, and stick the content to be posted on the magnetic plate 19. The magnetic plate 19 can not only fix various magnetic display materials, but also fix non-magnetic display content through iron fixings, making it very simple and quick to replace the display content without using any tools or glue, which greatly improves work efficiency. At the same time, the anti-static coating applied can reduce the air mixed between the display content and the magnetic plate 19, making the laid display content more After the posting is completed, close the protective window 14, rotate the threaded fixing rod 18 back into the plug block 15, turn on the power supply in the lower layer of the inner cavity of the buried device box 1, and make the driving motor 7 work. The rotating shaft of the driving motor 7 drives the rotating shaft 10 to rotate, so that the rotating disk 8 rotates, and the follower disk 9 rotates. The rotation of the follower disk 9 makes the limiting column 11 on the upper surface do a circular motion. When the limiting column 11 moves to one end close to the rotating disk 8, it is inserted into the toggle groove provided at the pointer end of the rotating disk 8, and the rotating disk 8 is driven to rotate by pushing the inner wall of the toggle groove, so that the rotating disk 8 drives the conical mounting body 4 to rotate through the rotating rod 3, and the angle of each rotation is ninety degrees. Through the above operation, all three-sided display contents can be displayed to people on the same side.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
