[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] Example 1: This utility model provides a soundproof armored fireproof door, including a door assembly, which consists of an outer mechanism 1 and an inner mechanism 2; the outer mechanism 1 includes a decorative door body 101 and a cold-rolled steel plate 102, the cold-rolled steel plate 102 is fixedly installed inside the decorative door body 101, and the decorative door body 101 is made of fireproof material; the inner mechanism 2 includes a mounting door body 201, the mounting door body 201 is fixedly installed on the side of the decorative door body 101, and the mounting door body 201 is installed on the door frame through connectors.

[0026] In this embodiment, a sealing cover 1011 is provided on the outer side of the decorative door 101, and the outer diameter of the sealing cover 1011 is larger than the outer diameter of the decorative door 101. In use, the outer mechanism 1 adopts a design with an internal cold-rolled steel plate 102. The lightweight design reduces the weight of the outer mechanism 1, making it easier to operate the door assembly. The cold-rolled steel plate 102 is a core component of the outer mechanism 1. The cold-rolled steel plate 102 is a specially treated steel plate with excellent pressure resistance and impact resistance, which can withstand extreme external forces, providing strong safety and durability for the door assembly. At the same time, the presence of the decorative door 101 also improves the aesthetics of the door assembly, meeting the needs for aesthetics and convenience. It is stable in use. When the door assembly is closed, the sealing rubber strip 103 will completely fit against the inner wall of the door frame, and the sealing rubber strip 103 can be squeezed and deformed by the door frame and the sealing cover 1011, thereby improving the airtightness of the door assembly and also improving the sound insulation effect.

[0027] In this embodiment, the inner side of the sealing cover 1011 is provided with an installation groove 1012, and a sealing rubber strip 103 is installed inside the installation groove 1012. In use, the design of the installation groove 1012 facilitates the replacement of the sealing rubber strip 103, and can quickly replace the aged sealing rubber strip 103 to keep the airtightness of the door assembly always in a normal state, making it flexible and convenient to use.

[0028] In this embodiment, the inner mechanism 2 further includes an inner frame 202 and a fireproof perlite board 203. The inner frame 202 is fixedly installed inside the door body 201. Two fireproof perlite boards 203 are provided, and the two fireproof perlite boards 203 are respectively fixedly connected to both sides of the inner frame 202. Fireproof rubber pads are fixedly installed on the outer side of the fireproof perlite board 203. In use, the cooperation between the outer mechanism 1 and the inner mechanism 2 enables the door assembly to have the functions of sound insulation, fire prevention and sealing. The inner mechanism 2 also adopts a lightweight design. While enhancing the overall strength of the inner mechanism 2, the fireproof perlite board 203 and the inner frame 202 also realize the lightweight design of the inner mechanism 2, further improving the weight reduction effect. Moreover, the fireproof perlite board 203 and the fireproof rubber pad can improve the fire resistance of the inner mechanism 2, and improve the sound insulation performance, fire resistance performance and durability of the door assembly.

[0029] In this embodiment of the disclosure, the inner frame 202 is provided with multiple sets of filling cavities 2021, and the filling cavities 2021 are filled with rock wool material. The rock wool material is kept in a soft state. In use, the filling cavities 2021 are filled with rock wool. The rock wool should not be compressed and compacted. The rock wool, which is kept in a soft state, can play a good sound insulation role, prevent external noise from penetrating into the internal space, and ensure the comfort of people in the internal space.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, after the door body 201 and the door frame are connected by connectors, the door assembly can be opened and closed. The outer mechanism 1 adopts a design with an internal cold-rolled steel plate 102. The lightweight design reduces the weight of the outer mechanism 1, making it easier to operate the door assembly. The cold-rolled steel plate 102 is the core component of the outer mechanism 1. The cold-rolled steel plate 102 is a specially treated steel plate with excellent pressure and impact resistance, capable of withstanding extreme external forces, providing strong safety and durability for the door assembly. At the same time, the presence of the decorative door body 101 also improves the aesthetics of the door assembly, meeting the needs for both aesthetics and convenience. The outer side of the decorative door body 101 is provided with a sealing cover 1011. When the door assembly is closed, the sealing rubber strip 103 will completely fit against the inner wall of the door frame, and the sealing rubber strip 103 can be deformed by the door frame and the sealing cover 1011, thereby improving the airtightness of the door assembly and also improving sound insulation. The design of the mounting groove 1012 facilitates the replacement of the sealing rubber strip 103, allowing for quick replacement of aged sealing rubber strips 103 to maintain the door assembly's airtightness at all times. The combined use of the outer mechanism 1 and the inner mechanism 2 enables the door assembly to have sound insulation, fireproofing, and sealing functions. The inner mechanism 2 also adopts a lightweight design. The fireproof perlite board 203 and the inner frame 202 enhance the overall strength of the inner mechanism 2 while also achieving a lightweight design, further improving the weight reduction effect. In addition, the fireproof perlite board 203 and the fireproof rubber pad can improve the fireproof performance of the inner mechanism 2, and improve the sound insulation, fireproofing, and durability of the door assembly. The filling cavity 2021 is filled with rock wool. The rock wool should not be compressed and compacted, so that the rock wool in a loose state can play a good sound insulation role, preventing external noise from penetrating the interior space and ensuring the comfort of people in the interior space.

[0032] In another embodiment, the door 201 is connected to the door frame via a silent connector, which includes, but is not limited to, a silent hinge to reduce noise generated by the door assembly when opening and closing. A smoke sensor is installed on the decorative door 101. When the smoke sensor detects a fire in the external space, it can trigger the fire extinguishing and alarm devices to remind people in the internal space to evacuate effectively and control the fire in its early stages.
