Description

Technical Field

[0001] The utility model relates to the technical field of sunshade nets, in particular to a multi-layer high-density plastic sunshade net device. Background Art

[0002] With the acceleration of urbanization and the increasing demand for outdoor activities, sunshade nets, as an important outdoor sheltering facility, are widely used in parks, streets, commercial areas, outdoor activity venues and other places. However, the materials used in traditional sunshade nets are usually ordinary plastic nets or cloths, which have limited sunshade effects and poor durability. They are easily damaged and deformed in harsh environments such as high temperature and strong wind, and do not meet people's demand for high-quality sunshade facilities. In this context, the emergence of multi-layer high-density plastic sunshade nets can effectively solve the problems of traditional sunshade nets;

[0003] The existing multi-layer high-density plastic sunshade net is generally at a constant height when in use. When facing different usage environment requirements, it is necessary to replace the brackets of different heights and sizes, but this will cause the overall use cost of the sunshade net to be too high. At the same time, in order to ensure the stability of the existing multiple high-density plastic sunshade net during use, it is generally necessary to reinforce the sunshade net with additional fixing devices, but this will cause the fixing device to be disassembled and reinstalled when the sunshade net needs to be replaced, which makes the entire device inconvenient to use.
