Background Art

[0002] As we all know, in the construction industry of our country, in order to promote construction safety, a hanging bracket or hanging device for hanging or installing corresponding construction safety information is often set up on the construction site. However, most of the existing hanging brackets or hanging devices are integrally welded, with complex structures, difficult to carry, and occupy a large transportation space. More importantly, it is time-consuming and laborious to install or disassemble. At the same time, it cannot be flexibly installed and adjusted according to actual needs to meet different needs, and it is time-consuming and laborious to install and disassemble.

[0003] At present, the hanging of traditional propaganda slogans is divided into two types: fixed and mobile. Among them, fixed propaganda slogans are disposable structures, and it is difficult to reuse the fixed foundation. There is a long construction period and construction difficulties. Professionals are required for construction, such as welders and electricians. In addition, it is not flexible to carry, move and use, and its use is limited in many areas. The existing mobile propaganda slogan hanging frame design is not flexible, and it can be divided into two situations. One is simple and light, but due to the limitation of the strength and weight of the structure itself, it can only meet the installation and hanging of small slogans. Compared with large slogans, it cannot be well displayed, so most of them are used in small occasions; it cannot meet the use needs of medium and large exhibition venues. One is a heavy propaganda slogan, the main weight of which is concentrated on the base. Although this can meet the use requirements of medium and large exhibition venues, it is heavy and brings many difficulties to handling and use, and often requires more manpower and material resources. And because of its bulkiness, it is incompatible with the venue, becoming a beauty and coordination defect of the entire venue. In short, it is often very inconvenient.

[0004] Therefore, it is the key to solve the above-mentioned technical problems to develop a propaganda slogan hanging device for building construction that is light, quick and convenient to install and remove, and highly practical. Summary of the invention
