[0002] At present, when constructing work surfaces in the construction field, it is generally necessary to reserve horizontal openings on the floor slabs, but these openings pose safety hazards during the construction process. In order to avoid safety hazards, scaffolding is generally used to set up protective railings, and protective nets are hung at the openings. Although this protection method can prevent people from approaching the openings, it cannot prevent falling objects from falling from the openings through the mesh of the protective net, causing safety hazards. Another protection method is to use a protective cover to cover and block. Although it can achieve airtight sealing, the protective cover is often moved manually during use, causing safety hazards. Therefore, there is an urgent need for a reversible opening protection that is arranged in advance on the working surface to solve the above-mentioned problems. Utility Model Content
