Anti-falling supporting frame of curtain wall panel

The utility model relates to the technical field of curtain walls, in particular to an anti-falling supporting frame of a curtain wall panel, when the curtain wall panel is installed, a fixing block of the curtain wall panel is fixedly connected with a fixing cavity in an embedded mode, then a rotating handle is adjusted, a rotating lead screw is driven to rotate, and then the curtain wall panel is installed. When the curtain wall panel is installed, the threaded block and the linkage block are driven to move along the rotating lead screw, the linkage block can abut against the pressing block, the pressing block drives the embedding column to move downwards, the embedding column and the embedding groove are fixedly connected in an embedded mode, then the installation cavity is covered through the covering plate, and installation of the whole curtain wall panel is completed. According to the structure, the curtain wall panel can be prevented from falling off, and the safety coefficient of the building curtain
