Connecting structure for fixing metal door

The utility model relates to the technical field of metal door connecting structures, in particular to a connecting structure for fixing a metal door, which is characterized in that one side of a metal door body is provided with a door frame, the side edge of the door frame is fixedly connected with a limiting rod, and the side edge of the door frame is fixedly connected with a base; the bottom end of the side edge of the door post is fixedly connected with a bottom plate, a rotating seat is rotatably connected above the bottom plate and is fixedly connected with the base, and the side edge of the door post is fixedly connected with a limiting sleeve which is rotatably connected with the limiting rod; the metal door has the advantages that a plane bearing structure is adopted to replace a traditional hinge structure to serve as a rotating support of the metal door, the weight of the metal door is greatly reduced, the structural stability is improved, meanwhile, the multiple sets of limiting rods and limiting
