[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1-8 The utility model provides a technical solution: an anti-collision outward-opening fire door, comprising a fixed door frame 1, the inner walls on both sides of the fixed door frame 1 are connected to the fire door 2 by a hinge shaft, and the two fire doors 2 are provided with anti-collision accessories, one of which includes a swing door 9 and a soft spring 10, the swing door 9 is connected to the square groove at the front end of the fire door 2 by a rotating shaft, and the soft spring 10 is fixedly connected between the swing door 9 and the fire door 2, and the upper and lower ends of the two fire doors 2 are provided with fixed accessories, one of which includes a sliding shell 14, electromagnetic switch 13, two telescopic springs 12 and push rod 11, the sliding shell 14 is fixedly connected to the upper inner wall of the fire door 2, the electromagnetic switch 13 is fixedly connected to the lower end of the sliding shell 14, the two telescopic springs 12 are fixedly connected to the upper end of the electromagnetic switch 13, the push rod 11 is fixedly connected to the upper ends of the two telescopic springs 12, and the push rod 11 is slidably connected in the sliding shell 14. This design solves the problem that the original device needs to be buffered by a buffer plate, but when the explosion impact force is strong, it will also cause the fire door to be compressed and deformed, making it difficult to open.

[0026] As the first embodiment of the present invention: the upper and lower ends of the fixed door frame 1 are fixedly connected with triangular bars 7, and the left and right ends of the fixed door frame 1 are fixedly connected with four fixed inclined plates 3. The triangular bars 7 fixedly installed on the fixed door frame 1 can increase the impact resistance of the fixed door frame 1, and prevent the fixed door frame 1 from being deformed after being subjected to a strong impact. The fixed inclined plates 3 installed on both sides of the fixed door frame 1 can reduce the deformation effect of the fixed door frame 1 by bending when the fixed door frame 1 is subjected to an impact. The front upper ends of the two fire doors 2 are fixedly connected with temperature sensors 4, and the surfaces of the two temperature sensors 4 are provided with a transparent protective layer. The temperature sensors 4 installed in front of the fire doors 2 sense the temperature in the house, and then sound an alarm through the alarm light 6 and the speaker 5. The transparent protective layer provided on the surface of the temperature sensor 4 can reduce the damage to the temperature sensor 4 caused by the shock wave. Two baffles 8 are fixedly connected to the inner walls on both sides of the rear end of the fixed door frame 1. A rubber layer is provided between the four baffles 8 and the fire door 2. The baffles 8 installed in the fixed door frame 1 can be used to limit the fire door 2 and prevent the fire door 2 from opening after being impacted. The rubber layer provided between the baffles 8 and the fire door 2 can reduce the damage caused by the baffles 8 to the fire door 2. The upper end of the push rod 11 is slidably connected between the fire door 2 and the fixed door frame 1. The left and right ends of the two swing doors 9 are provided with triangular structures. The push rod 11 slides between the fire door 2 and the fixed door frame 1 to fix the fire door 2 in the fixed door frame 1. One end of each swing door 9 is provided with a triangular structure to limit the swing door 9 in the square groove on the surface of the fire door 2. An alarm light 6 is fixedly connected to the front upper end of the fixed door frame 1, and a speaker 5 is fixedly connected to the front upper end of the fixed door frame 1. The alarm light 6 installed in front of the fixed door frame 1 can be used to guide escaping personnel to escape through the fire door 2, and the speaker 5 set in front of the fixed door frame 1 can make an alarm to guide escaping personnel to take shelter.

[0027] As a second embodiment of the present utility model: when the fixed door frame 1 is installed on the wall, the fixed inclined plate 3 and the triangular bar 7 need to be embedded in the wall. In the event of a fire, the temperature sensor 4 will sense the rising temperature of the surrounding environment and will control the alarm light 6 and the horn 5 to sound an alarm. The alarm light 6 will illuminate the escapee, and the horn 5 will indicate the road conditions for the escapee. After the escapee escapes by opening the fire door 2, the electromagnetic switch 13 is controlled to cut off the power by an external button. The push rod 11 will fix the fire door 2 in the fixed door frame 1 under the elastic force of the telescopic spring 12. After the fire door 2 is impacted, the explosive gas will rush open the swing door 9 and enter the fire door 2. The swing door 9 will close the fire door 2 under the elastic force of the soft spring 10. The explosive gas inside the fire door 2 and the room resist each other, thereby increasing the anti-collision effect of the fire door 2.
