[0002] Fire door core is the core filling material of fire door. It is mainly made of inorganic environmentally friendly materials and has key properties such as fire resistance, heat insulation and sound insulation. It is installed inside the fire door.

[0003] For example, the Chinese authorized patent with announcement number CN219903650U (A Fireproof Door Core) includes a door core outer shell, inside which a high-temperature resistant reinforcing mesh is provided, and a flame-retardant layer is connected to the inner side of the high-temperature resistant reinforcing mesh. This utility model enhances the fireproof, flame-retardant, and heat-insulating performance of the fireproof door core by providing a flame-retardant layer, a heat insulation component, and a graphite filling layer inside the door core outer shell. Furthermore, the heat insulation component includes a first heat insulation layer, a second heat insulation layer, and a heat insulation cavity, further enhancing the heat insulation performance of the fireproof door core. The high-temperature resistant reinforcing mesh and support frame inside the door core outer shell effectively improve the overall strength of the fireproof door core. The support columns and buffer springs inside the support frame enhance the shock and pressure resistance of the fireproof door core, preventing it from being bent or broken, thus affecting its fireproof and heat-insulating performance.

[0004] However, existing fire door core installation interfaces are all fixed by external screws to the sealing plate, which is inconvenient for installation and disassembly and makes it difficult to replace the fire door core; therefore, it does not meet the current needs. In response, we have proposed a quick installation interface for fire door cores filled with pearl cotton. Utility Model Content

[0005] The purpose of this utility model is to provide a quick installation interface for a pearl cotton-filled fireproof door core, so as to solve the problem mentioned in the background art that the existing fireproof door core installation interfaces are fixed by external screws on the sealing plate, which is inconvenient for installation and disassembly and makes it difficult to replace the fireproof door core.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick installation interface for a pearl cotton-filled fireproof door core, comprising: a fireproof door body and a connection port, wherein the connection port is located on one side surface of the fireproof door body, and the inner walls on both sides of the connection port near the opening are provided with moving grooves, a sealing plate assembly is provided inside the space formed by the two moving grooves, and the sealing plate assembly moves along the moving grooves, an installation groove is provided on the center bottom surface of the moving grooves, a fixing component is installed inside the installation grooves, and the connection port is filled with a fireproof door core.

[0007] Preferably, the center top surface of the movable groove is provided with a limiting groove, and the top surface of the limiting groove is provided with a movable opening.

[0008] Preferably, the sealing plate assembly includes a first sealing plate and a second sealing plate, with the second sealing plate located on one side of the first sealing plate, and the first and second sealing plates moving along two moving grooves respectively.

[0009] Preferably, a push plate is provided on one side of the upper surface of both the first sealing plate and the second sealing plate, and the push plate moves along the limiting groove.

[0010] Preferably, a magnetic absorbing sheet is embedded on one side surface of both the first sealing plate and the second sealing plate, and the first sealing plate and the second sealing plate are magnetically fixed to the bottom surface of the moving groove by the magnetic absorbing sheet.

[0011] Preferably, the fixing component includes a limiting baffle that moves up and down along the mounting groove, and the fixing component also includes a compression spring with spring fixing seats at both ends.

[0012] Preferably, one end of the fire door body is rotatably connected to the door frame via an external hinge, and a door lock is provided on the other side of the fire door body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides movable grooves on both sides of the inner wall of the connection port. The first sealing plate and the second sealing plate move along the two movable grooves respectively. The fireproof door core is inserted into the fireproof door body along the connection port. The first sealing plate and the second sealing plate are pushed again to make them contact each other. At this time, after the limiting baffle loses the squeezing force, it moves up along the installation groove through the elasticity of the compression spring. The two limiting baffles squeeze the first sealing plate and the second sealing plate respectively to prevent the first sealing plate and the second sealing plate from moving along the movable groove, thereby sealing the connection port and preventing the fireproof door core from falling off. When replacing the fireproof door core, it is only necessary to open the first sealing plate and the second sealing plate in the same way to replace it. It is simple and convenient, without the need for tools, which improves the convenience of installation and replacement. It solves the problem that the existing fireproof door core installation interface is fixed by the external screw of the sealing plate, which is inconvenient for installation and disassembly and makes it difficult to replace the fireproof door core.

[0015] (2) By embedding magnetic strips on one side surface of the first sealing plate and the second sealing plate, when the first sealing plate and the second sealing plate move along the moving groove to open the connection port, the first sealing plate and the second sealing plate are magnetically fixed to the bottom surface of the two moving grooves respectively by the magnetic strips, which improves the stability of the first sealing plate and the second sealing plate after opening, avoids automatic movement along the moving groove and affects the installation and disassembly of the fire door core, and improves convenience.

The space is equipped with a sealing plate assembly 3, which moves along the moving groove 6. The center bottom surface of the moving groove 6 is provided with an installation groove 12. The installation groove 12 is equipped with a fixing assembly 13. The fixing assembly 13 includes a limiting baffle 15, which moves up and down along the installation groove 12. The fixing assembly 13 also includes a compression spring 16. Both ends of the compression spring 16 are provided with spring fixing seats 17. The elastic force of the compression spring 16 facilitates the adjustment of the limiting baffle 15 along the installation groove 12.

[0023] A limiting groove 11 is provided on the center top surface of the moving groove 6, and a moving opening 14 is provided on the top surface of the limiting groove 11. The sealing plate assembly 3 includes a first sealing plate 7 and a second sealing plate 8, and the second sealing plate 8 is located on one side of the first sealing plate 7. The first sealing plate 7 and the second sealing plate 8 move along the two moving grooves 6 respectively.
