Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of publicity boards, and in particular to a service management culture publicity board. Background Art
[0002] Cultural publicity columns are facilities or devices used to display and disseminate cultural, educational, and publicity content, and are usually set up in public places, schools, communities, etc. Its main purpose is to convey cultural information, policies and regulations, social activities, works of art, etc. to the public, and to enhance people's cultural literacy and social awareness. Cultural publicity columns are usually presented in the form of text, pictures, posters, etc., with a strong visual impact, which can attract people's attention and play a role in dissemination and education.
[0003] For example, a sociologically-based community governance service management cultural propaganda column disclosed in Chinese Patent Publication No. (CN115100978A) records: "It includes a propaganda frame and a support frame, the propaganda frame is located on the inner side of the support frame, and the four outer corners of the propaganda frame are fixedly installed with connecting blocks welded to the support frame, and a U-shaped frame is fixedly installed on the inner side of the propaganda frame, and a display board is fixed on one side of the U-shaped frame. A foam propaganda board is provided on one side of the display board, and a clamping mechanism is provided on the other side of the display board. The present invention has a reasonable structure and is easy to operate. It is convenient to disassemble and replace the foam propaganda board, which reduces the trouble of staff in replacing propaganda posters and improves the efficiency of staff in replacing propaganda posters. It effectively avoids the problem that it is difficult to quickly tear off the propaganda posters for replacement in the existing cultural propaganda columns, which is inconvenient for staff to operate and time-consuming and labor-intensive. At the same time, it prevents the dust on the outside of the transparent board from affecting the propaganda effect of the foam propaganda board, which is conducive to the use of the cultural propaganda column. More convenient".
[0004] In summary, it can be seen that the existing technology has improved the efficiency of staff in replacing promotional posters and reduced the trouble of staff in replacing promotional posters.

[0055] Specifically, the surface of the slide rod 27 is slidably connected to a reciprocating frame 28, one end of the reciprocating frame 28 away from the slide rod 27 is arranged on the surface of the screw rod 23, and the screw rod 23 is threadedly connected to the reciprocating frame 28, and the surface of the reciprocating frame 28 is fixedly connected to a cleaning wipe 29.
[0056] Through the above structural design, the active transmission shaft 7 and the driven transmission shaft 10 rotate while driving the worm 25 on their surfaces to rotate respectively, the worm 25 rotates while driving the turbine 24 to rotate, the turbine 24 rotates while driving the screw 23 to rotate, the screw 23 rotates to make the reciprocating frame 28 slide on the surface of the slide bar 27, and because the cleaning wipe 29 is in close contact with the inner surface of the perspective glass 37, the cleaning wipe 29 can clean the inside of the perspective glass 37 while moving, thereby avoiding frequent opening of the display frame 4 to clean the inside thereof;
[0057] The picture can be rolled up and released while the active transmission shaft 7 and the driven transmission shaft 10 rotate. The movement of the reciprocating frame 28 is synchronized with the rolling up and releasing of the picture. After the picture is released, the reciprocating frame 28 can move to the other end of the slide bar 27. When the servo motor 6 is turned on again, the reciprocating frame 28 moves in the opposite direction, thereby realizing reciprocating cleaning of the inside of the perspective glass 37.
[0058] Embodiment 3:

[0061] Through the above structural design, when the display picture is replaced, the protective door 35 is opened, and the rotating frame 33 is rotated on the surface of the active transmission shaft 7 and the driven transmission shaft 10 to make the elastic clamping block 34 escape from the inside of the slot 32. At this time, the picture stops being limited and can be quickly removed, and one end of the new picture is clamped into the inside of the slot 32. After completion, the rotating frame 33 is rotated to make the elastic clamping block 34 clamped into the inside of the slot 32 to limit one end of the picture. After completion, the picture is rolled up;
[0062] After winding is completed, the other end of the pulled frame passes through the tensioning roller 20 and moves to the middle of the slot 32 on the surface of the driven transmission shaft 10.
