description The invention relates to the technical field of elevator cars, in particular to a safety protection device for preventing accidental movement and overspeed of an elevator car. The safety protection device comprises an elevator side column, a top seat, a lifting motor and the elevator car, wherein the top seat is fixedly installed at the top end of the elevator side column, the lifting motor is fixedly installed at the top end of the top seat, the outer wall of the output end of the lifting motor is sleeved with a lifting belt, a lifting wheel is fixedly installed at the top end of the elevatorcar, and the lifting wheel is connected with the lifting belt. According to the safety protection device for preventing accidental movement and overspeed of the elevator car, by arranging a tooth block and a first transmission gear, extrusion between a loop bar and the elevator side column can be generated when the elevator stops, then the situation that looseness occurs between the elevator sidecolumn and the connecting
