Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, and in particular relates to an impact-resistant steel fireproof door. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. It is specifically used to isolate fire sources in residential buildings. It plays a huge role in fire fighting. Once a fire occurs, people can get a chance to escape through fire doors.

[0003] Existing fire doors are generally installed by rotation through hinges and locked with ordinary latches. However, when a fire occurs, there is a high-pressure shock such as an explosion. The fire door that only cooperates with the hinges and latches has limited protection against the high-pressure shock, causing the fire door to open under the action of the high-pressure shock, thereby losing its fire protection effect.

[0009] In this technical solution, the fire door body and the door frame are hinged, and through the cooperation between the set reinforcement structure and the driving structure, the reinforcement structure can be inserted into the upper and lower surfaces of the fire door body, which is beneficial to improving the impact resistance of the fire door.

[0010] In the above technical solution, further, the reinforcement structure includes:

[0011] A groove, wherein the groove is symmetrically arranged on the upper and lower surfaces of the inner wall of the door frame, and a movable plate is slidably arranged in the groove;

[0012] Ear plates, which are fixedly arranged at both ends of the movable plate and connected to the driving structure to drive the movable plate to move;

[0013] A limit block is arranged on the top surface of the movable plate, and limit grooves are arranged on the upper and lower surfaces of the fire door body.

[0014] In the present technical solution, the movable plate can be driven to move by the driving structure, thereby driving the limit block to be inserted into the limit groove, and the reinforcement structure is symmetrically arranged up and down, which is beneficial to improving the impact resistance of the fire door.

[0015] In the above technical solution, further, the driving structure includes:

[0017] A first bevel gear, wherein the first bevel gear is symmetrically arranged at the end of the first screw rod, and a second bevel gear is meshedly arranged on the side of the first bevel gear, and a central axis of the second bevel gear passes through the inner wall of the cavity and protrudes from the outer surface of the door frame;

[0018] A driving motor, wherein the driving motor is arranged on the outer wall of the door frame, and the output shaft is connected to the central shaft of the second bevel gear;

[0019] An air avoidance groove, wherein the air avoidance groove is arranged below the groove and is communicated with the cavity;

[0020] A second screw rod, the second screw rod is rotatably arranged in the air-avoiding groove, and a second support seat is arranged between the outer wall of the second screw rod and the air-avoiding groove;

[0021] A third bevel gear, the third bevel gear is arranged on the end surface of the first screw rod close to the clearance groove, and a fourth bevel gear is arranged on the end of the second screw rod, and the third bevel gear is meshed with the fourth bevel gear;

[0022] Wherein, the ear plate is threadedly connected to the first screw rod.

[0023] In the present technical solution, the driving motor can drive the second bevel gear and the first bevel gear to rotate, and drive the first screw to drive the ear plate to move, thereby driving the reinforcement structure to cooperate with the fire door body, and through the cooperation between the set second screw, the third bevel gear, and the fourth bevel gear, the ear plate can drive the movable plate to move horizontally, which is beneficial to improving the stability of the device.
