DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Refer to Figure 1-5The utility model provides a technical solution, a steel door with automatic alarm function, including a door frame 1, characterized in that a steel door 2 is hingedly installed inside the door frame 1, a smoke alarm 4 is arranged on the surface of the steel door 2, an explosion-proof glass 3 is arranged inside the steel door 2, and a locked door handle 5 is arranged on the surface of the steel door 2. The explosion-proof glass 3 is arranged to facilitate outdoor personnel to observe the fire situation indoors, an escape door 6 is hingedly installed inside the steel door 2, and a driving component is arranged inside the steel door 2, and the driving component includes a rotating shaft 8 fixedly installed inside the steel door 2, a rotating disk 9 is fixedly installed on one end of the rotating shaft 8, and a first rotating shaft 8 is fixedly installed on the other end of the rotating shaft 8. The helical gear 10 and the surface of the bidirectional screw rod 12 are fixedly mounted with a second helical gear 13, and the second helical gear 13 is meshed with the first helical gear 10. By setting the driving component, the turntable 9 is rotated to rotate the rotating shaft 8, which drives the first helical gear 10 to rotate, so that the bidirectional screw rod 12 rotates, drives the moving plate 14 to move, and then drives the second helical gear 13 to rotate. The steel door 2 is provided with an inner cavity 11, and the inner cavity 11 is rotatably mounted with a bidirectional screw rod 12, and the surface of the bidirectional screw rod 12 is threadedly mounted with a moving plate 14, and a slider 15 is fixedly mounted on the surface of the moving plate 14, and a slide groove 16 is provided inside the inner cavity 11, and the slider 15 and the slide groove 16 are slidable. The movable plate 14 is connected, and the movable plate 14 can be limited by the setting of the slider 15 and the slide groove 16, so that the movable plate 14 is more stable when moving. A card block 17 is fixedly installed on the surface of the movable plate 14, and a card slot 7 is opened on the surface of the escape door 6, and the card slot 7 and the card block 17 are set correspondingly. By moving the movable plate 14, the card block 7 enters or leaves the card slot 17, and the escape door 6 can be closed and opened. A steel plate 18 is arranged inside the steel door 2, and a fireproof filler 19 is arranged on one side of the steel plate 18, and the fireproof filler 19 is located between the two groups of steel plates 18. The fireproof performance of the steel door 2 is increased by setting the fireproof filler 19. A flame retardant layer 20 is arranged on the side. Through the setting of the smoke alarm 4, the smoke produced by the combustion will trigger the smoke alarm 4, causing the smoke alarm 4 to sound an alarm to remind people in the building. Through the setting of the explosion-proof glass 3, it is convenient for people outside the steel door 2 to observe the fire situation inside. Through the setting of the fireproof filler 19 and the flame retardant layer 20, the spread of heat can be reduced to avoid burns to people on the other side when opening the door for rescue. Through the setting of the driving component, the second bevel gear 13 is rotated, which in turn drives the two-way screw rod 12 to rotate, so that the movable plate 14 moves, and then the card block 17 is disengaged from the card slot 7, so that the escape door 6 can be opened, which is convenient for people in the room to escape.

[0022] In use: when a fire occurs indoors, a large amount of thick smoke is generated. Through the setting of the smoke alarm 4, the smoke generated by the combustion will trigger the smoke alarm 4, causing the smoke alarm 4 to sound an alarm to remind people in the building. Through the setting of the explosion-proof glass 3, it is convenient for people outside the steel door 2 to observe the fire situation inside. Through the setting of the fireproof filler 19 and the flame retardant layer 20, the spread of heat can be reduced to avoid burns to people on the other side when opening the door for rescue. When the locked door handle 5 is damaged, the turntable 9 is rotated to rotate the shaft 8, driving the first bevel gear 10 to rotate, and the first bevel gear 10 is meshed with the second bevel gear 13, so that the second bevel gear 13 rotates, thereby driving the two-way screw rod 12 to rotate, so that the movable plate 14 moves, and then the card block 17 is disengaged from the card slot 7, and the escape door 6 can be opened, which is convenient for people in the room to escape.
