Problems solved by technology

[0002] Leaflet advertisements are still the most frequently used means of cultural propaganda. In advertising, the larger the advertisement page, the more it can attract the attention of the general public. At the same time, the larger the advertisement page also needs a larger publicity bracket. Therefore, the promotional display racks in the streets and alleys are getting bigger and bigger. Although they are firmly fixed on the ground or buildings during installation, the huge advertising pages can block the airflow during use and form a strong wind in the wind. At the same time, it also forms a strong destructive force on the promotional display rack, which is why the larger the promotional display rack is, the easier it is to topple over.

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0031] like figure 1 , 2 , 4, the support 1 includes a base 11 and a frame column 12, the base 11 is a "U"-shaped metal frame, the base 11 is provided with anchor bolt holes 111, and the frame column 12 is "n"-shaped The metal frame, the bottom of the frame column 12 is fixedly connected with the base 11, and most of the metal frame is welded by rods. Shaped frame column 12, there is a gap between the rods and therefore the wind can pass through the metal frame, the whole bracket will not form a large wind resistance; the inner side of the frame column 12 is provided with a groove with a rectangular cross section, which is used to limit the balance bar The movement of 4 may cause the counterweight rod 4 to fly and hit nearby people or objects in the strong wind because the leaflet 2 is blown up by the strong wind, causing a safety hazard, so the co...
