Abstract

The invention relates to the technical field of fireproof doors, in particular to a fireproof door. The fireproof door comprises an overhead door, an installation frame and a control device, wherein the overhead door comprises a rectangular door body, a linkage block, an external threaded transmission shaft and a driven sprocket wheel; one end of the linkage block is fixedly connected onto the upper end of the rectangular door body and the other end of the linkage block is connected onto the external threaded transmission shaft through thread; the driven sprocket wheel is fixedly connected onto the lower end of the external threaded transmission shaft; and the bottom end of the external threaded transmission shaft is rotarily connected onto the top surface of the installation frame. The fireproof door has fireproof, flame-retardant, sealing and smoke-retardant functions; in case of fire, the smoke and the fire can be blocked, the fire can be prevented from spreading indoors, and smokeentering the room to do harm to a human body can be prevented.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door with the functions of fire prevention, flame retardancy and sealing and smoke resistance. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. However, the fire doors in the prior art have poor airtightness and cannot block the smoke. Contents of the invention [0003] The purpose of the present invention is to provide a fire door, which has the functions of fire prevention, flame retardancy and sealing and smoke resistance, which can block the smoke and fire in the event of a fire, prevent the fire from spreading...
