[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] Reference Figure 1 - Figure 5A fire door built-in alarm structure includes a mounting frame 1, a fire door body 2 rotatably connected inside the mounting frame 1, a mounting groove 3 on the outer side of the mounting frame 1, and an alarm mechanism on the top of the mounting frame 1. The alarm mechanism includes a patrol component and a power component, which work together. The patrol component includes an avoidance groove 41, which is located on the top side of the mounting frame 1. Fixing plates 42 are symmetrically fixedly connected to the front of the mounting frame 1. A rotating shaft 43 is rotatably connected between the two fixing plates 42. A half gear 44 is fixedly connected to the outer side of the rotating shaft 43. A fire sensor 45 is fixedly connected to the side of the half gear 44 away from the mounting frame 1. A sliding rod 46 is fixedly connected inside the avoidance groove 41. A rotating rack 47 is slidably connected to the outer side of the sliding rod 46. The rotating rack 47 and the half gear 44 are meshed together. The power assembly includes a cylinder 49, which is fixedly connected to the top of the mounting frame 1. A linkage rack 411 is fixedly connected to the telescopic end of the cylinder 49. A linkage gear 410 is rotatably connected to the top of the mounting frame 1. The linkage gear 410 and the linkage rack 411 are meshed together. A rotating plate 412 is fixedly connected to the top of the linkage gear 410. A sliding frame 48 is fixedly connected to the outer side of the rotating rack 47. A sliding wheel 413 is slidably connected inside the sliding frame 48. The bottom of the sliding wheel 413 is fixedly connected to the top of the rotating plate 412. Buzzers 5 are symmetrically fixedly connected to the front of the mounting frame 1. The buzzers 5 and the alarm mechanism work together.

[0024] In the above technical solution, considering the problem that fire doors lack fire alarm devices and cannot warn residents of the danger of fire and remind them to evacuate immediately, the specific operation is as follows:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the extension and retraction of the cylinder 49 drives the linkage rack 411 to move laterally back and forth, thereby causing the linkage gear 410 to rotate and drive the rotating plate 412 to rotate. The sliding wheel 413 slides inside the sliding frame 48, and the lateral back and forth movement of the sliding frame 48 drives the rotating rack 47 to slide laterally back and forth outside the sliding rod 46. The rotating rack 47 drives the half gear 44 to rotate back and forth outside the rotating shaft 43, and the half gear 44 drives the fire sensor 45 to swing back and forth on the front of the mounting frame 1. The fire sensor 45 can provide fire warning for a larger area. When a fire is detected, the fire sensor 45 sends a command to the buzzer 5, and the buzzer 5 sounds an alarm. Through the alarm mechanism, a fire warning can be provided for a larger area, and at the first moment of a fire, an alarm can be actively issued to people in the vicinity, so that people can discover the fire and evacuate immediately, greatly reducing the loss of life and property. The structure is simple and highly practical.

[0026] Reference Figure 1 -Figure 5 In a preferred embodiment, the inside of the fireproof door body 2 is provided with a fireproof observation window 6, and the glass arranged in the fireproof observation window 6 is fireproof glass. The outside of the fireproof door body 2 is symmetrically connected with a handle 7, and the handle 7 is made of fireproof material. The back of the mounting frame 1 is fixedly connected with a controller 8, and the fire disaster sensor 45, the air cylinder 49 and the buzzer 5 are electrically connected with the controller 8. Through the fireproof observation window 6, people can observe the fire, and through the controller 8, the staff can conveniently control the opening and closing of the fire disaster sensor 45, the air cylinder 49 and the buzzer 5, and the operation is more convenient.

[0027] Working principle: in actual use, the staff first installs the mounting frame 1 and the fireproof door body 2, and then starts the air cylinder 49, the telescopic end of the air cylinder 49 drives the transverse reciprocating movement of the linkage rack 411, and then the rotation of the linkage gear 410 drives the rotation of the rotating plate 412, the sliding wheel 413 slides in the inside of the sliding frame 48, and then the transverse reciprocating movement of the sliding frame 48 drives the transverse reciprocating sliding of the rotating rack 47 outside the sliding rod 46, and then the rotating rack 47 drives the reciprocating rotation of the half gear 44 outside the rotating shaft 43, and then the half gear 44 drives the reciprocating swing of the fire disaster sensor 45 on the front of the mounting frame 1, and the fire disaster sensor 45 can give a fire warning in a larger range, and when the fire is detected, the fire disaster sensor 45 sends an instruction to the buzzer 5, and the buzzer 5 gives an alarm to alarm the people around and remind people of the occurrence of the fire.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. The replacement can be the replacement of part of the structure, device, method step, or the complete technical solution.
