Description

rotating billboard

technical field

The invention relates to an outdoor advertising device, in particular to a rotary advertising board.

Background technique

With the advent of the information age, technology is also advancing with each passing day. The ways of information exchange are also becoming more and more abundant. Outdoor advertising has become the second best media after TV to convey various kinds of information to the public. There are many types of outdoor advertising. The most eye-catching advertising methods are widely known to the public. Single-column outdoor billboards generally have two forms: double-sided billboards and three-sided billboards. Single-column billboards place the billboard on a special support column, and The price of the support pole is high. In order to meet the development strategy of the smart city, it can be used in conjunction with the communication tower, and one pole can be used for multiple purposes. However, there are also some problems with this traditional iron tower with billboards: 1. In order to ensure that the advertisements are eye-catching, the billboards are large in size, so the billboards have a large windward area, and ordinary billboards cannot release strong wind loads. When the structural strength of the billboard is exceeded, the billboard will have the risk of rupture or even collapse. Second, the site type is limited, the area is large, the service life is short, and the cost is high. Due to the large windward area, the diameter of the tower body is required to be relatively large, and the base area will also increase, so this type of billboard is not suitable for urban dense areas, and the service life of the single-column type is not long; In addition, the variety of shaft materials will cause the overall cost of the tower to be relatively much more expensive.
