Technical Field
[0001] The utility model relates to the technical field of propaganda columns, in particular to a propaganda column with good windproof effect. Background Art
[0002] Propaganda columns are an important tool for self-promotion and are often used in scenic spots, streets, factories or hotels. General propaganda columns mainly include propaganda column frames and propaganda column frames fixed on the propaganda column frames. Transparent panels are hinged on the propaganda column frames. The propaganda images in the propaganda column frames can be replaced by opening the transparent panels. Generally, stainless steel is used as the frame, tempered glass or endurance board is used as the panel, and aluminum alloy is used as the ceiling. The panel can be opened to replace the propaganda images. Since general propaganda columns use a structure with two supporting legs under a frame, the windproof ability is poor. In windy weather, they are easily blown down or even blown away, which can easily hurt others.
[0003] Announcement No. CN 217086096 U discloses a propaganda column, comprising: a propaganda column frame, which is a rectangular structure with an opening on the front side and a hollow inside; connecting columns arranged at intervals on the left and right sides of the propaganda column frame, and two connecting blocks are welded at intervals on the upper and lower sides of the connecting columns close to the propaganda column frame; the limit blocks are fixedly connected to the propaganda column frame by bolts; propaganda columns are arranged on the outside of the connecting columns, and the sides of the propaganda columns close to the connecting columns are recessed with connecting grooves; a rain shelter arranged horizontally and fixed to the top of the connecting columns by bolts is present, but the above scheme has certain disadvantages.
[0004] In order to enhance the publicity effect, the existing publicity columns are generally provided with larger signboards. However, when strong winds blow, if the wind direction is directly facing the signboard, the large area of the signboard is subjected to greater force, causing the strong wind to blow directly toward the signboard. The front of the signboard is opposite to the strong wind, and the signboard is easily damaged by the strong wind. Not only does it cause property loss, but the fallen signboard may also injure the people under the billboard, thereby causing accidental casualties. It is impossible to divert and reduce the strong wind blowing toward the signboard when the front of the signboard contacts the strong wind. For this reason, we have proposed a publicity column with good windproof effect to solve the above problems. Utility Model Content

A card slot 4 is opened in the left and right ends of the limit frame 3. The two sets of card slots 4 are movably inserted in the windproof component. The upper and lower ends of the windproof component are provided with a support component, and the support component is rotatably connected to the limit frame 3. The device is unfolded by pulling the windproof component, and the windproof component is supported and fixed by the support component after being unfolded, so as to achieve the windproof effect of the publicity column 1;
[0024] Furthermore, the windproof component includes two groups of wind shields 5, both of which are movably inserted in the two groups of slots 4, and the two groups of wind shields 5 are hingedly installed with connecting plates 6 at one opposite end, and multiple groups of protrusions 8 are installed in sequence from top to bottom on the front side of one end of the two groups of wind shields 5 inserted in the two groups of slots 4, and multiple groups of slide grooves 9 are opened in sequence from top to bottom on the front inner walls of the two groups of slots 4, and multiple groups of protrusions 8 are movably inserted in the multiple groups of slide grooves 9. This structure pulls the connecting plate 6 to drive the two groups of wind shields 5 to unfold, and the protrusions 8 on the two groups of wind shields 5 slide in the multiple groups of slide grooves 9, thereby diverting the wind flow facing the billboard 1 when the two groups of wind shields 5 and the connecting plate 6 are unfolded.
[0025] Furthermore, the front inner walls of the two groups of slots 4 are both inclined, and the multiple groups of slide grooves 9 are consistent with the inclination angle of the front sides of the two groups of slots 4. This structure is based on the shape of the front inner walls of the two groups of slots 4, so that the front sides of the two groups of windshields 5 fit with the front sides of the inner walls of the two groups of slots 4 after they are unfolded.
[0026] Furthermore, a handle 7 is fixedly installed on the front side of the connecting plate 6. The handle 7 is made of aluminum alloy. The connecting plate 6 is pulled by holding the handle 7, and the material of the handle 7 prevents it from rusting when contaminated by rain.
