[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1-5The utility model provides an assembled fireproof door with good sealing performance, including an assembled fireproof door structure 1, the assembled fireproof door structure 1 includes a door frame 11, a door frame 12, a door closer 13, a connecting cavity 14, a No. 1 screw hole 15, a door leaf 16, a connecting rail 17, a No. 2 screw hole 18, an edge sealing strip 19, an embedding groove 110 and a bottom sealing strip 111. The door frame 12 is hingedly installed on the right wall inside the door frame 11, and the door frame 12 is L-shaped. The door closer 13 is screwed on the front part of the crossbeam of the door frame 12. The pull rod of the door closer 13 is screwed with the top edge of the front of the door frame 11. The door closer 13 can control the door frame 12 to close automatically into the inner side of the door frame 11. The bottom surface of the crossbeam of the door frame 12 is provided with a connecting cavity 14. The crossbeam of the door frame 12 is provided with a No. 1 screw hole 15 through the front and back, and the No. 1 screw hole 15 is connected with the inner side of the connecting cavity 14. The inner side of the door frame 12 is provided with a door leaf 16. A connecting rail 17 is welded and installed on the top of the door leaf 16. The connecting rail 17 is horizontally inserted and installed into the inner side of the connecting cavity 14. A No. 2 screw hole 18 is set through the connecting rail 17 from front to back. Bolts are inserted and installed inside the No. 1 screw hole 15 and the No. 2 screw hole 18, so as to lock the connecting rail 17 to the inner side of the connecting cavity 14. An edge sealing strip 19 is longitudinally fitted on the right side wall of the door leaf 16. A groove 110 is longitudinally opened on the left side wall of the longitudinal beam of the door frame 12. The edge sealing strip 19 is inserted into the inner side of the groove 110. The sealing of the side joint between the door leaf 16 and the door frame 12 is improved by the edge sealing strip 19 and the groove 110. Smoke is not easy to penetrate through the side joint between the door leaf 16 and the door frame 12. A bottom sealing strip 111 is horizontally fitted on the bottom edge of the door leaf 16. The bottom sealing strip 111 can seal the gap between the door leaf 16 and the ground, so that smoke is not easy to pass through.

[0023] To further explain, the length of the connecting rail 17 is consistent with the length of the top edge of the door leaf 16 to ensure that the connecting rail 17 and the connecting cavity 14 have sufficient connection strength so that the door leaf 16 can be stably hoisted on the inner side of the door frame 12.

[0024] To further illustrate, the longitudinal section of the connecting rail 17 is T-shaped, and the connecting cavity 14 matches the shape and size of the connecting rail 17, so that the connecting rail 17 and the connecting cavity 14 have good sealing after being inserted and installed, and smoke is not easy to penetrate through the top edge joint between the door leaf 16 and the door frame 12.

[0025] To further illustrate, the longitudinal section of the edge-sealing strip 19 is trapezoidal, and the embedding groove 110 matches the shape and size of the edge-sealing strip 19 , so that the edge-sealing strip 19 can be better and tightly embedded in the embedding groove 110 to ensure the sealing effect.

[0026] It is further explained that the number of edge sealing strips 19 is not less than 2, and the edge sealing strips 19 are distributed in parallel on the right side wall of the door leaf 16, the number of the embedded grooves 110 and the edge sealing strips 19 are consistent, and the position distribution corresponds to each other, which further improves the sealing of the side joints between the door leaf 16 and the door frame 12.

[0027] To further explain, both the bottom sealing strip 111 and the edge sealing strip 19 are made of fire-proof expansion rubber strips. When the fire-proof expansion rubber strips are exposed to a high temperature environment, they will expand due to heat, so that the bottom sealing strip 111 and the edge sealing strip 19 can automatically fit together to fill the sealing gap and prevent smoke from penetrating.

[0028] Here’s how it works:

[0029] First, when installing the assembled fire door structure 1, first install the door frame 11 into the preset door opening, then flip the door frame 12 from the inside of the door frame 11 to the outside, and then control the door leaf 16 to be installed on the inside of the door frame 12. During this process, the connecting rail 17 needs to be aligned with the connecting cavity 14 for insertion, so that the door leaf 16 is hoisted on the inside of the door frame 12, and then bolts are used to insert and install into the inside of the No. 1 screw hole 15 and the No. 2 screw hole 18, so as to lock the connecting rail 17 on the inside of the connecting cavity 14, thereby completing the installation of the assembled fire door structure 1.

[0030] Second, by providing an edge sealing strip 19 on the side wall of the door leaf 16, when the door leaf 16 is installed into the inner side of the door frame 12, the edge sealing strip 19 will be inserted into the inner side of the embedding groove 110 to improve the sealing of the side seam between the door leaf 16 and the door frame 12, so that smoke is not easy to penetrate through the side seam between the door leaf 16 and the door frame 12. By providing a bottom sealing strip 111 on the bottom edge of the door leaf 16, the bottom sealing strip 111 can seal the gap between the door leaf 16 and the ground, so that smoke is not easy to pass through.

[0031] Third, when the door leaf 16 needs to be disassembled, it is only necessary to remove the bolts in the No. 1 screw hole 15 and the No. 2 screw hole 18, and then move the door leaf 16 out until the connecting rail 17 completely leaves the inner side of the connecting cavity 14. The door leaf 16 can then be removed separately, while the door frame 12 remains on the door frame 11. There is no need to disassemble the door frame 11 hinges and the door closer 13, which greatly reduces the disassembly and assembly process and facilitates the disassembly and repair work.

[0032] The above are only preferred examples of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
