Description

Building entrance to a cave lift protector with adjustable Technical Field The utility model relates to the technical field of building structure safety protection, in particular to an adjustable lifting protection device for a building hole. Background With the diversification development of building forms, the device can be used for protecting the building holes, and can prevent personnel or objects from falling accidentally in the building construction process or prevent foreign matters from entering the holes in daily use after the building is constructed; The protection device with similar structure has a plurality of defects in practical use, such as that the existing protection device may lack an effective adjusting mechanism and is difficult to adapt to building holes with different sizes, and meanwhile, when the existing protection device faces building holes with different shapes, the protection device may need to be integrally replaced to adapt, so that the cost is high and the operation is complex, and therefore, an adjustable lifting protection device for the building holes needs to be designed. Disclosure of utility model In order to solve the technical problems, the utility model provides an adjustable lifting protection device for a building hole.
