Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fireproof, heat-insulating and anti-theft technology, and in particular relates to a fireproof, heat-insulating and anti-theft door. Background Technology
[0002] A security door is a door that can resist unauthorized opening under certain conditions for a certain period of time, possesses certain security protection performance, and meets the corresponding security level.
[0003] Some existing security doors have gaps between them and their frames, allowing cold air to easily enter the room when the door is closed, causing a drop in indoor temperature. Furthermore, some existing security doors have poor fire resistance; in the event of a fire, they are easily damaged and unable to effectively block the flames. Therefore, we propose a fire-resistant and heat-insulating security door. Utility Model Content
[0004] The purpose of this utility model is to provide a fireproof, heat-insulating, and burglarproof door to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a fireproof, heat-insulating, and burglarproof door, comprising:
[0006] A door frame, with a sealing frame fixedly installed inside, a door body hinged to the door frame, an anti-theft lock fixedly installed on the door body, a second fire-resistant expansion sealing strip that fits tightly against the door body fixedly installed on the side of the sealing frame near the door body, a first fire-resistant expansion sealing strip fixedly installed on the door body within the sealing frame, two reinforcing steel plates fixedly installed inside the door body, a steel frame fixedly installed between the two reinforcing steel plates, two stainless steel plates fixedly installed inside the door body between the two reinforcing steel plates, two fireproof plates fixedly installed inside the door body between the two stainless steel plates, and an insulation board fixedly installed inside the door body between the two fireproof plates.
[0007] In this technical solution, during daily use, when the door is closed, the first fire-resistant expansion sealing strip on the door will enter the sealing frame and will be in close contact with the inner wall of the sealing frame. At the same time, the door will be in close contact with the second fire-resistant expansion sealing strip. The first and second fire-resistant expansion sealing strips have a certain elasticity and sealing performance at room temperature, which can ensure that cold air from the outside will not enter the room. In addition, with the help of the insulation board, the heat inside the room can be blocked, preventing the heat inside the room from being lost to the outside, and at the same time, preventing the cold air from the outside from being transferred to the room.
[0008] In the event of a fire, fire-resistant expansion sealing strips one and two can rapidly expand when exposed to high temperatures. When the temperature rises to a certain threshold, the expanding agent begins to react chemically, producing gas, which causes the fire-resistant expansion sealing strips one and two to expand rapidly. This effectively fills the gap between the door and the door frame, preventing the passage of flames, smoke, and heat. Furthermore, with the action of the two fireproof boards, the fireproof boards can also act as heat insulation, slowing down the heat conduction rate. This allows the door to maintain its integrity during a fire, preventing the fire from spreading and avoiding further property damage.
[0009] With the steel frame and two reinforcing steel plates, the strength of the door is enhanced, preventing damage to the fireproof and insulation panels inside the door from external impacts. At the same time, with the two stainless steel plates, the excellent corrosion resistance of the stainless steel plates protects the fireproof and insulation panels between them, preventing them from corroding and ensuring a longer service life for the entire device before a fire occurs.
[0010] Furthermore, in the above technical solution, the sealing frame has a U-shaped structure, and the sealing frame and the door frame are integrally formed.
[0011] In this technical solution, the cooperation between the sealing frame and the fire-resistant expansion sealing strip 1 and the fire-resistant expansion sealing strip 2 is ensured to effectively enhance the sealing between the door and the door frame, thereby preventing cold air from entering the room.
[0012] In the above technical solution, both the first fireproof expansion sealing strip and the second fireproof expansion sealing strip are in the form of a U-shape.
[0013] In this technical solution, it is ensured that fire-resistant expansion sealing strip one and fire-resistant expansion sealing strip two can effectively enhance the sealing performance between the door body and the door frame.
[0014] In the above technical solution, the steel frame is further welded tightly to two reinforcing steel plates.
[0015] In this technical solution, the structural stability between the two reinforcing steel plates and the steel frame is ensured.
[0016] In the above technical solution, the steel frame is further described as having an X-shaped structure.
[0017] In this technical solution, the steel frame has an X-shaped structure, which ensures that the steel frame can provide strong support for the two reinforcing steel plates.
[0018] In the above technical solution, the fireproof expansion sealing strip is further fitted tightly against the inner wall of the sealing frame.
[0019] In this technical solution, the fire-resistant expansion sealing strip is designed to enhance the sealing between the sealing frame and the door, thereby blocking cold air from entering the room.
[0020] The beneficial effects of this utility model are:
[0021] This fireproof, heat-insulating, and burglarproof door, through the coordinated use of a sealed frame, fire-resistant expansion sealing strip 1, fire-resistant expansion sealing strip 2, reinforced steel plates, stainless steel plates, fireproof boards, insulation boards, and a steel frame, ensures enhanced sealing between the door body and the door frame, preventing cold air from entering the room. Simultaneously, it enhances the overall strength and fire resistance of the door. In the event of a fire, the door effectively prevents fire, slows down heat conduction, and maintains its integrity, preventing the spread of fire and avoiding further property damage.

[0036] Example 1:
[0037] Please see Figure 1 - Figure 7 As shown, this embodiment provides a fireproof, heat-insulating, and burglarproof door, including:
[0038] A door frame 1 has a sealing frame 4 fixedly installed inside it. A door body 2 is hinged to the door frame 1. An anti-theft lock 3 is fixedly installed on the door body 2. A fire-resistant expansion sealing strip 2 6 is fixedly installed on the side of the sealing frame 4 near the door body 2, which fits tightly against the door body 2. A fire-resistant expansion sealing strip 1 5 is fixedly installed on the door body 2 and inside the sealing frame 4. Two reinforcing steel plates 7 are fixedly installed inside the door body 2. A steel frame 11 is fixedly installed between the two reinforcing steel plates 7. Two stainless steel plates 8 are fixedly installed inside the door body 2 and between the two reinforcing steel plates 7. Two fireproof plates 9 are fixedly installed inside the door body 2 and between the two stainless steel plates 8. An insulation board 10 is fixedly installed inside the door body 2 and between the two fireproof plates 9.
[0039] In daily use, when the door 2 is closed, the fire-resistant expansion sealing strip 1 5 on the door 2 will enter the sealing frame 4 and will be in close contact with the inner wall of the sealing frame 4. At the same time, the door 2 will be in close contact with the fire-resistant expansion sealing strip 2 6. The fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 have a certain elasticity and sealing performance at room temperature, which can ensure that cold air from the outside will not enter the room. In addition, under the action of the insulation board 10, the heat inside the room can be blocked to prevent the heat inside the room from being lost to the outside, and at the same time, the cold air from the outside can be prevented from being transferred to the room.
[0040] When a fire occurs, the fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 can expand rapidly when exposed to the high temperature of the fire. When the temperature rises to a certain threshold, the expansion agent begins to undergo a chemical reaction, producing gas, which causes the fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 to expand rapidly. This effectively fills the gap between the door body 2 and the door frame 1, preventing the passage of flames, smoke and heat. In addition, under the action of the two fireproof boards 9, the fireproof boards 9 can play a role in heat insulation, slowing down the heat conduction speed, so that the door body 2 can maintain its integrity in the fire, prevent the fire from spreading, and avoid causing more property damage.
[0041] With the cooperation of the steel frame 11 and two reinforcing steel plates 7, the strength of the door body 2 can be enhanced, preventing damage to the fireproof plate 9 and insulation plate 10 inside the door body 2 due to external impacts. At the same time, with the cooperation of the two stainless steel plates 8, the stainless steel plates 8 have good corrosion resistance, which can protect the fireproof plate 9 and insulation plate 10 between the two stainless steel plates 8, preventing the fireproof plate 9 and insulation plate 10 from being corroded, and ensuring that the service life of the whole device is longer before a fire occurs.

In addition to the technical solutions of the above embodiments, it also has the following technical features: the sealing frame 4 has a U-shaped structure, and the sealing frame 4 and the door frame 1 are integrally formed.
[0044] In particular, ensuring the proper fit between the sealing frame 4 and the fire-resistant expansion sealing strip 5 and the fire-resistant expansion sealing strip 6 can effectively enhance the sealing between the door body 2 and the door frame 1, thereby preventing cold air from entering the room.

[0053] The steel frame 11 has an X-shaped structure, which ensures that the steel frame 11 can provide strong support for the two reinforcing steel plates 7.
[0054] Example 6:
[0055] This embodiment provides a fireproof, heat-insulating, and burglarproof door. In addition to the technical solutions of the above embodiments, it also has the following technical features: the fireproof expansion sealing strip 5 is tightly fitted to the inner wall of the sealing frame 4.
[0056] Among them, the fire-resistant expansion sealing strip 5 can enhance the sealing performance between the sealing frame 4 and the door 2, thereby blocking the cold air from the outside and preventing the cold air from entering the room.
[0057] It is worth noting that the fire-resistant expansion sealing strip 5 and the fire-resistant expansion sealing strip 6 are fire-resistant expansion sealing strips produced by Hebei Xufeng Rubber Products Co., Ltd. Their structure and principle are existing technologies, and will not be described in detail here.
[0058] Working principle: During daily use, when the door 2 is closed, the fire-resistant expansion sealing strip 1 5 on the door 2 will enter the sealing frame 4 and will be in close contact with the inner wall of the sealing frame 4. At the same time, the door 2 will be tightly fitted with the fire-resistant expansion sealing strip 2 6. The fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 have a certain elasticity and sealing performance at room temperature, which can ensure that cold air from the outside will not enter the room. In addition, under the action of the insulation board 10, the heat inside the room can be blocked to prevent the heat inside the room from being lost to the outside, and at the same time, it can also prevent the cold air from the outside from being transferred to the room.
[0059] When a fire occurs, the fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 can expand rapidly when exposed to the high temperature of the fire. When the temperature rises to a certain threshold, the expansion agent begins to undergo a chemical reaction, producing gas, which causes the fire-resistant expansion sealing strip 1 5 and the fire-resistant expansion sealing strip 2 6 to expand rapidly. This effectively fills the gap between the door body 2 and the door frame 1, preventing the passage of flames, smoke and heat. In addition, under the action of the two fireproof boards 9, the fireproof boards 9 can play a role in heat insulation, slowing down the heat conduction speed, so that the door body 2 can maintain its integrity in the fire, prevent the fire from spreading, and avoid causing more property damage.
[0060] With the cooperation of the steel frame 11 and two reinforcing steel plates 7, the strength of the door body 2 can be enhanced, preventing damage to the fireproof plate 9 and insulation plate 10 inside the door body 2 due to external impacts. At the same time, with the cooperation of the two stainless steel plates 8, the stainless steel plates 8 have good corrosion resistance, which can protect the fireproof plate 9 and insulation plate 10 between the two stainless steel plates 8, preventing the fireproof plate 9 and insulation plate 10 from being corroded, and ensuring that the service life of the whole device is longer before a fire occurs.
