Problems solved by technology

[0004] The object of the present invention is to provide a propaganda stand, by setting a clamping mechanism, the clamping mechanism includes several "L" shaped corner clips and several elastic ropes, and the elastic ropes fix the "L" shaped corner clips on the publicity frame Inside, the "L"-shaped corner clamping block clamps and fixes the four corners of the poster, so as to adapt to the fixed posting of posters of different sizes; at the same time, a dust removal mechanism is set up. The scraper moves up and down, which solves the problem that the existing propaganda device has a complex fixed structure to adapt to posters of different sizes, is driven by power, and is inconvenient to connect to electricity; at the same time, there is a lack of dust removal device in rural areas, and the problem of losing the propaganda effect after being covered with dust

Embodiment 1

[0033] see figure 1 As shown, the present invention is a publicity platform, including a publicity frame 1, the publicity frame 1 adopts a rectangular frame structure, and the interior of the publicity frame 1 is used for affixing a publicity poster 9. The lower end of the publicity frame 1 is fixedly connected with a support seat 101 , and the front of the publicity frame 1 is provided with transparent glass for observing the content of the poster 9 .

[0034] see Figure 1-Figure 2 As shown, the promotional frame 1 is fixedly connected with a clamping mechanism suitable for displaying different poster sizes. The clamping mechanism includes four "L"-shaped corner clips 2 and elastic ropes 5. One end of the elastic rope 5 is connected to the "L"-shaped corner The corners of the clip block 2 are fixedly connected, and the other end of the elastic cord 5 is fixedly connected with the four corners of the inner wall of the propaganda frame 1 . The "L"-shaped corner clamping bloc...

Embodiment 2

[0038] see Figure 4 As shown, the clamping mechanism also includes several "one"-shaped edge clamping blocks 3, and the "one"-shaped edge clamping blocks 3 use the same structure as the "L"-shaped corner clamping block 2 to clamp and fix the poster 9. One end of the elastic cord 5 is fixedly connected with the middle part of the "one" type edge clip 3, and the other end of the elastic cord 5 is fixedly connected with the inwall of the publicity frame 1. The "one"-shaped edge clip 3 and the "L"-shaped corner clip 2 are evenly clamped on the edge of the poster 9, on the one hand, the force on the poster 9 is uniform, and the stretching process of the elastic rope 5 is avoided, causing the poster 9 to tear and tear On the other hand, the evenly arranged "one"-shaped edge clips 3 and "L"-shaped corner clips 2 are equivalent to adding a circle of wrapping to the edge of the poster 9, which increases the aesthetics of the poster 9.

Embodiment 3

[0040] see Figure 5 As shown, the upper surface of the scraper 6 is provided with a sliding groove 602 , and the sliding groove 602 is slidably connected with a magnifying glass 8 . The magnifying glass 8 can move up and down with the scraper 6, and can also act on the scraper 6, so as to realize the enlargement of the text at any position on the poster 9, which is convenient for people with poor eyesight to read. The section of the chute 601 adopts a "convex" shape, and the lower end of the magnifying glass 8 is adapted to the "convex" section, so as to prevent the magnifying glass 8 from falling off from the chute 602.
