A lamp holder 10 is installed on the surface of the support plate 5, and the lamp holder 10 is symmetrically distributed. The light bar 11 is installed on the side of the lamp holder 10. By installing the light bar 11, when the external light is dim, the light bar 11 is used to illuminate the area around the fire door with a monitoring function, so that the monitoring device 14 will not be affected by the external light when in use, which is very convenient to use.

[0031] A monitoring device 14 is installed at the bottom of the support plate 5, a fixing frame 13 is welded to the bottom of the support plate 5, a groove 15 is provided on the side of the fixing frame 13, a transparent protective cover 12 is clamped inside the fixing frame 13, an external threaded rod 17 is fixedly connected to the side of the transparent protective cover 12, the external threaded rod 17 is located inside the groove 15, a nut 18 is installed at the other end of the external threaded rod 17, the nut 18 is fitted to the side of the fixing frame 13, the monitoring device 14 is located inside the transparent protective cover 12, by installing the transparent protective cover 12, the transparent protective cover 12 is used to protect the monitoring device 14 from external collision, and at the same time, the transparent nature of the transparent protective cover 12 will not affect the monitoring effect of the monitoring device 14, thereby providing a protective effect for the monitoring device 14, and the protectiveness is relatively strong when in use.

[0032] The inside of the door frame 1 is connected to the fire door body 2 through a rotating shaft. The surface of the fire door body 2 is fixedly connected to a fixing seat 3. A handle 4 is welded to the other end of the fixing seat 3. By installing the handle 4, when the fire door body 2 needs to be opened, the handle 4 can be used to provide a force point for the fire door body 2. At this time, the handle 4 can be directly used to drive the fire door body 2, which is very convenient to use.

[0033] A limit frame 9 is welded on the top of the support plate 5, and the power supply 8 is located inside the limit frame 9. By installing the limit frame 9, the limit frame 9 is used to provide a limit effect for the power supply 8, and further provides stability to the power supply 8, so that the stability is strong during use.

[0034] The other end of the nut 18 is welded to the fixing rod 16, and the other end of the fixing rod 16 is welded to the rotating handle 19. The anti-slip strip 20 is welded on the surface of the rotating handle 19, and the anti-slip strip 20 is distributed in a ring form.
