[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a fireproof roller shutter with an evacuation fire door, comprising a door frame 1. The door frame 1 serves as the basic support structure for the entire fireproof roller shutter device, and its main function is to fix and install other components, ensuring the stability and robustness of the entire device. A protective shell 2 is fixedly connected to the front side of the door frame 1. The protective shell 2 protects the internal mechanical transmission components, preventing dust, debris, etc., from entering and affecting their operation. Two fixing blocks 3 are fixedly connected to the left and right sides of the protective shell 2. Connecting rods 4 are slidably connected inside the fixing blocks 3. The fixing blocks 3 provide stable sliding tracks and support points for the connecting rods 4, allowing the connecting rods 4 to slide smoothly inside, thereby achieving linkage with other components. The connecting rods 4 are key components connecting the elliptical block 5 and the stop block 9. During the operation of the device, their sliding motion drives the elliptical block 5 to move, thereby achieving coordinated work with other components.

[0034] Elliptical blocks 5 are rotatably connected to the top of the connecting rod 4. The unique elliptical shape of the elliptical blocks 5 allows them to form specific mechanical interactions with other components during rotation. Connected to an external operating mechanism via a pull rod 6, the rotation of the elliptical blocks 5, when pulled by an external force, can cause the connecting rod 4 to slide. Springs 7 are fixedly connected to adjacent sides of the fixed block 3. In the initial state of the device, springs 7 are in a compressed state, storing a certain amount of elastic potential energy. When the fireproof roller shutter needs to be opened, springs 7 release energy, providing initial power for the rapid opening of the shutter, accelerating its opening speed. Simultaneously, they also play a certain buffering and auxiliary reset role during the closing process, ensuring the smooth operation of the device. Stop blocks 9 are fixedly connected to adjacent sides of the connecting rod 4. The main function of the stop blocks 9, installed on the connecting rod 4, is to limit the sliding stroke of the connecting rod 4, preventing it from detaching from the fixed block 3 during movement, ensuring the mechanical integrity and stability of the device. Two fixed plates 21 are fixedly connected to the front side of the door frame 1, and a smoke-proof sealing assembly is slidably connected inside the door frame 1.

[0035] Reference Figure 3 , Figure 5The sealing assembly includes a roller shutter slat 10, which is the main body of the fireproof roller shutter and plays a crucial role in fire prevention and heat insulation. Its internal structure is ingeniously designed, housing components such as a motor 11 and an arc gear 12. The left and right sides of the roller shutter slat 10 are slidably connected to the interior of the door frame 1. The motor 11 is fixedly connected inside the roller shutter slat 10, serving as the power source for its raising and lowering. Upon receiving a control signal, the motor 11 drives the arc gear 12 to rotate, thereby causing the entire roller shutter slat 10 to rise and fall. One of the arc gears 12 is fixedly connected to the drive end of the motor 11. The two arc gears 12 mesh with each other, transmitting the rotational power of the motor 11 to the connecting rod 13, thus realizing the raising and lowering action of the roller shutter slat 10. A fixing rod 14 is fixedly connected inside the roller shutter slat 10, providing a stable rotation fulcrum for one of the arc gears 12, ensuring the accuracy and stability of the arc gear 12 during operation. Another arc-shaped gear 12 is rotatably connected to the outside of the fixed rod 14 to ensure the stable operation of the entire transmission system and to ensure that the roller shutter slat 10 can open or close quickly and smoothly in the event of a fire, effectively playing a fire prevention role. The outside of one arc-shaped gear 12 is meshed with the outside of the other arc-shaped gear 12. The bottom of the two arc-shaped gears 12 are respectively fixedly connected to the connecting rod 13. The connecting rod 13 plays a key role in the transmission system, connecting the arc-shaped gear 12 and the connecting rod 15, and converting the rotational motion of the arc-shaped gear 12 into the up-and-down reciprocating motion of the connecting rod 15.

[0036] Reference Figures 3 to 5Two connecting rods 13 are rotatably connected to their bottoms, and two pressing plates 16 are rotatably connected to their bottoms. The bottoms of the connecting rods 15 and the pressing plates 16 are rotatably connected. The up-and-down movement of the connecting rods 13 causes them to swing, thereby moving the pressing plates 16 up and down. During the closing process of the fireproof roller shutter, the pressing plates 16 are pushed downward by the connecting rods 15, pressing the sealing plate 17, thus significantly enhancing the sealing between the roller shutter slats 10 and the door frame 1. The top of the pressing plates 16 contacts the bottoms of the two baffles 18. The baffles 18 are installed above the pressing plates 16 and have a dual function of limiting and guiding. On the one hand, the baffles 18 limit the upward movement of the pressing plates 16, ensuring that they operate within the normal working range and avoiding device failure due to excessive displacement. Sliding columns 20 are fixedly connected to the bottoms of the two baffles 18, and two springs 19 are fixedly connected to the bottom of the pressing plates 16. The springs 19 are in a stretched state when the fireproof roller shutter is opened, storing a certain amount of elastic potential energy. When the shutter 10 is closed, the spring 19 releases energy, assisting the compression plate 16 in pressing the sealing plate 17 more tightly, further enhancing the sealing effect. The bottom of the two sliding columns 20 is fixedly connected to the sealing plate 17. The sealing plate 17 and the compression plate 16 are tightly fitted together. When the fireproof shutter is closed, it is pressed tightly against the door frame 1 by the compression plate 16, forming a tight sealing barrier that effectively prevents the passage of smoke, flames and heat. The adjacent sides of the two (21) are in contact with the outside of the (2). The fixing plate 21 works in conjunction with the protective shell 2. When the fireproof shutter is closed, the fixing plate 21 is precisely inserted into the slot 8 of the protective shell 2, playing an important role in fixing and sealing.

[0037] The protective shell 2 has two slots 8 inside, which cooperate with the grooves of the fixing plate 21 to provide precise positioning and a stable connection. When the fireproof roller shutter is closed, the fixing plate 21 inserts into the slots 8, making the protective shell 2 and the fixing plate 21 tightly connected. The two grooves inside the two fixing plates 21 ensure the stability and sealing of the entire device and enhance the connection strength between the fireproof roller shutter and the door frame 1. The two connecting rods 4 are sleeved inside the two springs 7. During the closing process, they can buffer the movement of the components, assist the components to return to their original position smoothly, ensure the smooth and reliable operation of the device, and extend its service life. Two pull rods 6 are fixedly connected to the front of the two elliptical blocks 5. The pull rods 6 serve as a direct connection between the operator and the elliptical blocks 5. Their length and position are carefully designed to facilitate the application of external force in emergency situations. The inner sliding connection of the roller shutter slat 10 is to the outside of the extrusion plate 16, which improves the fire resistance performance of the fireproof roller shutter, ensures the integrity of the fire compartment, and creates favorable conditions for personnel evacuation and fire rescue. The inner sliding connection of the roller shutter slat 10 is to the outside of the sealing plate 17, which ensures the sealing effect in the event of a fire and provides strong protection for the fire resistance performance of the fireproof roller shutter.

[0038] Working principle: The door frame 1 serves as the basic support, the protective shell 2 protects the internal transmission components, the fixing block 3 provides sliding support for the connecting rod 4 to achieve linkage, the elliptical block 5 rotates with external force to drive the connecting rod 4, the spring 7 stores potential energy and can open quickly, the stop block 9 restricts the connecting rod 4, the fixing plate 21 cooperates with other components to enhance the stability of the device, ensure that the fireproof roller shutter can play an effective role in a fire, and protect the safety of people and property. For regular maintenance work, such as cleaning the internal transmission components, checking the spring elasticity and lubricating the connecting rod 15 joint, the quick-opening protective shell 2 makes these operations more convenient and efficient, which helps to extend the service life of the fireproof roller shutter and ensure that it maintains good performance during long-term use.

[0039] In the sealing assembly, the roller shutter slat 10 is a key fireproof component. It integrates components such as the motor 11. The motor 11 provides the sealing power for the roller shutter slat 10, driving the arc gear 12 to rotate. The two arc gears 12 mesh with each other, transmitting the power through the connecting rod 13. The fixing rod 14 provides a stable fulcrum for the arc gear 12. From power supply to power transmission, and finally driving the sealing plate 17 to move, a complete system is formed, ensuring that the fireproof roller shutter can operate quickly and smoothly during a fire, effectively preventing fire. For firefighters, the sealed roller shutter also facilitates their rescue work. They can carry out rescue operations such as breaking and demolition on the relatively smoke-free and cool side, more effectively rescuing trapped personnel.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
