[0027] Example 1

[0028] A propaganda device, such as Figure 1-6As shown, it includes a box body 1, a accommodating space 2 is provided in the box body 1, a motor 3 is provided on the bottom wall of the accommodating space 2, an output shaft of the motor 3 is fixedly connected to a support plate 4, a sleeve 5 for winding a poster 22 is detachably connected to the support plate 4, specifically, protrusions 7 are provided on the upper surface of the support plate 4 at intervals along the circumferential direction, and slots 8 matching the protrusions are provided on the bottom surface of the sleeve 5 at intervals along the circumferential direction.

[0029] A mounting plate 6 that moves laterally is provided on one side of the sleeve 5, and an electric slide rail 11 is provided on the top and bottom of the accommodating space 2, respectively. The mounting plate 6 moves laterally through the electric slide rail 11, and the two sides of the poster 22 that are away from each other are detachably connected to the sleeve 5 and the mounting plate 6, respectively. The connection method of the poster 22 and the sleeve 5 is as follows: a hard fixing strip 9 is fixedly connected to the side of the poster close to the sleeve 5, the sleeve 5 is a hollow structure, and a gap 10 that penetrates the side wall of the sleeve 5 from top to bottom is provided on the side of the sleeve 5, and the hard fixing strip 9 passes through the gap 10 and is located inside the sleeve 5, and magnets are arranged at intervals on the hard fixing strip 9, and iron sheets that match the magnets are arranged at intervals on the inner wall of the sleeve 5. The connection method of the poster 22 and the mounting plate 6 is as follows: a plurality of fixing bolts 12 are arranged at intervals on the outer surface of the mounting plate 6, and a through hole matching the fixing bolt 12 is provided on the side of the poster 22 away from the hard fixing strip 9, and the poster is hung on the fixing bolt 12 through the through hole, and an end cap 13 is threadedly connected to the end of the fixing bolt 12, and the size of the end cap 13 is larger than the size of the through hole. When in use, first put the through hole on the poster on the fixing bolt 12, and then tighten the end cover 13 to complete the connection between the poster 22 and the mounting plate 6. In addition, the bottom of the box body 1 is fixedly connected with a leg 19, and the bottom of the leg 19 is provided with a bottom plate 20, and the bottom plate 20 is provided with a fixing hole, and the bolt is passed through the fixing hole and then fixedly connected with the embedded part located in the ground.

[0030] A plurality of data boxes 14 are arranged on the side of the accommodation space 2. The front of the data boxes 14 is a transparent plate. A U-shaped notch 15 is arranged on the upper end of the transparent plate to facilitate the replacement of knowledge popularization materials. In addition to large propaganda posters, cases for residents to better understand knowledge are made into cards and inserted into the data boxes 14 for display. The size of the cards is slightly smaller than the data boxes 14. Glass doors 16 are hinged on both sides of the box 1. Door locks 17 are arranged between the glass doors 16. A sealing strip is arranged between the glass door 16 and the box 1 to prevent rain and dust from entering the box to contaminate the posters as much as possible.

[0031] An LED display board 18 is provided on the top of the box 1, which is an LED scrolling screen for displaying an introduction to the knowledge being promoted. Residents can observe the types of knowledge being promoted when they are at a relatively far distance, and can choose whether to go and read according to their own interests, without having to go up to the front to know what the displayed knowledge is about.

[0032] Working and use process:

[0033] The sleeve 5 is removed from the support plate 4, and the rolled poster 22 (such as Figure 2 As shown, the middle is a hollow structure), which is sleeved on the outside of the sleeve 5, and the hard fixing strip 9 is passed through the slit 10 on the sleeve 5, and then the long side of the hard fixing strip 9 is adjusted to be perpendicular to the path passing through the slit 10 (as shown in FIG. Figure 3 As shown), magnets are arranged at intervals on the hard fixing strip 9, and iron sheets matching the magnets are arranged at intervals on the inner wall of the sleeve. The position of the hard fixing strip 9 remains unchanged through the cooperation between the magnets and the iron sheets. Then, the sleeve 5 is placed on the support plate 4, the through hole on the poster is put on the fixing bolt 12, and then the end cover 13 is tightened to complete the connection between the poster 22 and the mounting plate 6, and the motor 3 and the electric slide rail 11 are started to slowly unfold the poster. When the electric slide rail 11 drives the mounting plate 6 to move to the far right of the accommodating space 2, the poster 22 is fully unfolded, and the far left end of the poster 22 will not be separated from the sleeve because the hard fixing strip 9 is located in the gap 10. When the poster is put away, the motor 3 rotates in the opposite direction, and the electric slide rail 11 drives the mounting plate 6 to move toward the left, and the poster 22 is rolled up again, and the end cover 13 is unscrewed to complete the disassembly of the poster 22 and the mounting plate 6, and then the sleeve 5 is removed, and the poster 22 is removed from the sleeve 5.
