Description

Technical Field

[0001] This utility model relates to the field of fire doors, specifically a steel insulated fire door. Background Technology

[0002] Fire-resistant insulated doors are doors that provide both heat insulation and fire protection during a fire. They consist of a door frame, door leaf, fire-resistant hinges, fire-resistant locks, and other fire-resistant hardware, effectively isolating flames and high temperatures to protect personnel. These doors are made of fire-resistant materials that block smoke and flames, preventing the spread of fire. Fire-resistant insulated doors are commonly used in fire escape routes, elevator shafts, and passageways near high-temperature equipment—locations requiring special protective measures.

[0003] In the event of a fire, the temperature inside a room gradually rises. As the temperature increases, and no one notices and attempts to extinguish the fire, the door panel itself heats up under the flames. This can cause burns to people trying to escape through the fire door, preventing it from opening in time and severely impacting the optimal escape window. Furthermore, flames can spread through the gaps between the door frame and the door panel, creating a fire hazard in areas that were originally safe on the other side of the door. Therefore, the safety of the fire door is compromised.

[0004] Therefore, we propose a steel insulated fireproof door. Summary of the Invention

[0005] The purpose of this utility model is to provide a steel insulated fireproof door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel insulated fireproof door, comprising a fireproof frame and a fireproof door panel, wherein the fireproof door panel is rotatably installed on the inner wall of the fireproof frame, the fireproof frame is provided with a fire extinguishing mechanism for extinguishing fire and cooling, and the fireproof frame is provided with a temperature detection mechanism.

[0007] The fire extinguishing mechanism includes a first fixed plate, an air guide pipe, and a rectangular nozzle. The first fixed plate is symmetrically fixedly connected to the inner wall of the fireproof frame. The air guide pipe is symmetrically passed through and fixedly connected to the inside of the first fixed plate. The rectangular nozzle is fixedly connected to the end of the air guide pipe away from the fireproof frame.

[0008] Preferably, the fire extinguishing mechanism further includes a fire extinguisher, which is symmetrically and fixedly connected inside the fireproof frame, and the fire extinguisher is connected and fixedly connected to the gas duct. The fireproof frame is symmetrically and slidably connected with a sliding plate, and a first toothed plate is fixedly connected between the two sliding plates. An abutment rod is fixedly connected to the end of the first toothed plate near the fire extinguisher.

[0009] Preferably, the detection mechanism includes a temperature detector, which is fixedly connected to the outer wall of the first fixed plate. An electric telescopic rod is fixedly installed on the side of the temperature detector near the first fixed plate. A second toothed plate is fixedly connected to the end of the electric telescopic rod away from the temperature detector. The first fixed plate and the second toothed plate are slidably connected through each other. The interior of the fireproof frame is symmetrically fixedly connected with second fixed plates. A gear rod is rotatably connected between the two second fixed plates, and the gear rod meshes with the second toothed plate.

[0010] Preferably, the first toothed block plate meshes with the gear rod.

[0011] Preferably, there is an electrical connection between the electric telescopic rod and the temperature detector, and the second toothed block plate is configured as a double toothed block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By controlling the fire extinguishing mechanism through the testing agency to extinguish the flames around the fireproof door panel, the flames around the fireproof door panel are prevented from leaking out through the gap between the fireproof frame and the fireproof door panel, thereby preventing the risk of fire on the other side of the fireproof door panel and improving the fire isolation effect of the fireproof door panel.

[0014] 2. By using a temperature detector to monitor the indoor temperature in a timely manner, the fireproof door panel is prevented from overheating due to excessive indoor temperature. This also prevents burns to escaping personnel and makes it difficult to open the fireproof door panel in a timely manner, thus improving the safety of the equipment. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 5 The figure shows a steel insulated fire door, including a fireproof frame 1 and a fireproof door panel 2. The fireproof door panel 2 is rotatably installed on the inner wall of the fireproof frame 1. The fireproof frame 1 is equipped with a fire extinguishing mechanism for fire extinguishing and cooling, and a temperature detection mechanism for temperature detection.

[0026] The fire extinguishing mechanism includes a first fixed plate 3, an air duct 4, and a rectangular nozzle 5. The first fixed plate 3 is symmetrically fixed to the inner wall of the fireproof frame 1. The air duct 4 is symmetrically passed through and fixedly connected to the inside of the first fixed plate 3. The rectangular nozzle 5 is fixedly connected to the end of the air duct 4 away from the fireproof frame 1.

[0027] The fire extinguishing mechanism also includes a fire extinguisher 6, which is symmetrically and fixedly connected inside the fireproof frame 1. The fire extinguisher 6 is also connected to the gas duct 4. The fireproof frame 1 is symmetrically and slidably connected with a sliding plate 9. A first toothed plate 8 is fixedly connected between the two sliding plates 9. An abutment rod 7 is fixedly connected to the end of the first toothed plate 8 near the fire extinguisher 6.

[0028] In this embodiment, when the gear rod 14 inside the detection mechanism drives the first toothed plate 8 to move away from the gear rod 14, the first toothed plate 8 drives the slide plate 9 to slide synchronously inside the fireproof frame 1. This causes the slide plate 9 to drive the abutment rod 7 to abut against the switch on the fire extinguisher 6, causing the extinguishing dust placed inside the fire extinguisher 6 to be sprayed into the air guide pipe 4. The extinguishing dust is then transported through the air guide pipe 4 to the inside of the rectangular nozzle 5, and then sprayed towards the fireproof door panel 2 through the outlet of the air guide pipe 4. The detection mechanism controls the fire extinguishing mechanism to extinguish the flames around the fireproof door panel 2, preventing the flames around the fireproof door panel 2 from leaking out through the gap between the fireproof frame 1 and the fireproof door panel 2. This prevents the fire hazard from appearing on the other side of the fireproof door panel 2 and improves the fire isolation effect of the fireproof door panel 2.

[0029] Example 2: Please refer to Figure 3 - Figure 6 This embodiment further illustrates Example 1. The detection mechanism shown in the figure includes a temperature detector 10, which is fixedly connected to the outer wall of the first fixed plate 3. An electric telescopic rod 11 is fixedly installed on the side of the temperature detector 10 near the first fixed plate 3. A second toothed plate 12 is fixedly connected to the end of the electric telescopic rod 11 away from the temperature detector 10. The first fixed plate 3 and the second toothed plate 12 are slidably connected through each other. A second fixed plate 13 is symmetrically fixedly connected inside the fireproof frame 1. A gear rod 14 is rotatably connected between the two second fixed plates 13, and the gear rod 14 meshes with the second toothed plate 12.

[0030] The first toothed block plate 8 meshes with the gear rod 14, the temperature detector 10 is electrically connected to the equipment using a power supply, the electric telescopic rod 11 is electrically connected to the temperature detector 10, and the second toothed block plate 12 is configured as a double toothed block.

[0031] In this embodiment, when a fire occurs, as the indoor temperature gradually increases, the temperature detector 10 begins to detect the indoor temperature. When the temperature is too high, the temperature detector 10 electrically controls the electric telescopic rod 11 to extend towards the side closer to the gear rod 14. This causes the electric telescopic rod 11 to drive the second toothed plate 12 to move towards the side closer to the gear rod 14 inside the first fixed plate 3. During the movement of the second toothed plate 12, it drives the gear rod 14, which meshes with it, to rotate between the second fixed plates 13. During the rotation of the gear rod 14, it drives the first toothed plate 8, which meshes with it, to move away from the gear rod 14, and triggers the fire extinguishing mechanism to work. By detecting the indoor temperature in a timely manner through the temperature detector 10, the fire door panel 2 is prevented from becoming too hot due to excessive indoor temperature. This also prevents the fire door panel 2 from causing burns to escaping personnel and makes it difficult to open the fire door panel 2 in a timely manner, thus improving the safety of the device.
