[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model is a fireproof aluminum door with a sealing structure, comprising a fireproof door 1 and a door frame 2, wherein the inner side surface of the door frame 2 is recessed to form a sealing groove 15 of a frame-type structure, and the four outer sides of the fireproof door 1 are recessed to form a mounting groove 8 of a frame-type structure, wherein a plurality of sealing plates 9 are arranged in the mounting groove 8, and the plurality of sealing plates 9 are combined to form a sealing frame, and screw holes are arranged on the inner side surfaces of the sealing plates 9, and a groove 3 is arranged on the side surface of the fireproof door 1 facing the room, and an axial hole is arranged on the inner ring surface of the groove 3 opposite to the screw hole, and a screw rod 7 is arranged in the axial hole, one end of the screw rod 7 is threadedly connected to the screw hole, and the other end extends into the groove 3, and a gear 6 is installed thereon, and a driving mechanism for driving the gear 6 to rotate is installed inside the groove 3.

[0023] In this embodiment, the driving mechanism includes a crown tooth 4, a shaft 12, a first bearing and a handwheel 5. The first bearing is embedded and installed at the center of the groove 3. One end of the shaft 12 is installed in the inner ring of the first bearing, and the other end is fixedly connected to the handwheel 5. The crown tooth 4 is installed on the shaft 12 and is meshed with multiple gears 6.

[0024] In this embodiment, both ends of the sealing plate 9 are inclined, and both ends of the sealing plate 9 are provided with assembly grooves 13, and sealing blocks 10 are provided in the assembly grooves 13. Adjacent sealing blocks 10 are set in abutment with each other. Positioning holes 14 are provided on the inner wall surfaces of the assembly grooves 13, and positioning rods are inserted into the positioning holes 14. One end of the positioning rod is installed on the sealing block 10, and the other end of the positioning rod is installed with a compression spring, and the other end of the compression spring is installed on the inner wall surface of the positioning hole 14.

[0025] In this embodiment, the shaft hole expands outward toward one end of the groove 3 to form an annular groove, in which a second bearing 11 is installed. The inner ring of the second bearing 11 is fixedly connected to the screw 7. The screw can be fixed by the second bearing so that the screw can only rotate around the second bearing, thereby avoiding axial displacement and increasing stability after installation.

[0026] In this embodiment, the outer side surface of the sealing frame is arranged flush with the side surface of the fire door 1, so that the fire door can be opened and closed smoothly during normal use.

[0027] In this embodiment, the fire door 1 is made of metal aluminum to ensure the strength and fireproof effect of the fire door.

[0028] Once a fire occurs, the shaft rod can be rotated by the hand wheel, and the rotation of the shaft rod drives the crown teeth, and the rotation of the crown teeth synchronously drives the rotation of multiple gears, and the gears synchronously drive the screw rod. The rotating screw rod can synchronously drive the sealing plate to move outward along the inner side of the installation groove until the sealing plate is inserted into the sealing groove of the door frame. As the sealing plate moves outward, the sealing plates will open. At this time, the positioning rod is pushed outward by the elastic energy of the compression spring, and the movement of the positioning rod drives the sealing block. The sealing block that moves outward can seal the gap between the sealing plates, so as to ensure the sealing between the door frame and the fire door, thereby increasing the fire prevention effect.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
