The unsuitable area marker has the following shortcomings: 1. The marker is heavy and inconvenient to place and recycle; 2. There are many metal parts such as rivets on the closed marker panel, which may fall off and cause aging and falling risk after long-term use, which may fall on the pavement; it may be blown by the wind, thus producing high-risk foreign objects; 3. The windproof effect is not good, and it is easy to fall down, which cannot play an effective indicating role after falling down, and may cause aircraft to misslide; 4. In strong wind weather, the fallen closed sign needs to be placed by workers many times, which affects work efficiency. UTILITY MODEL CONTENT
