[0018] The utility model is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0019] like Figures 1 to 3 As shown, the present embodiment provides an embedded fireproof and smokeproof sealing strip, comprising a mounting base 1 and a sealing assembly 2 mounted on the mounting base 1. Specifically, the mounting base 1 is made of aluminum alloy material, so that the fireproof and smokeproof sealing strip is more solid and reliable. A first concave cavity 11 is provided on one side of the mounting base 1, and a second concave cavity 12 is provided on the other side of the mounting base 1. The sealing assembly 2 includes a first fireproof expansion seal 21, a second fireproof expansion seal 22 and a sealing strip 23, the first fireproof expansion seal 21 is installed in the first concave cavity 11, and the second fireproof expansion seal 22 is installed in the second concave cavity 12. Specifically, the first fireproof expansion seal 21 is pasted in the first concave cavity 11, and the second fireproof expansion seal 22 is pasted in the second concave cavity 12. The second concave cavity 12 is located on both side walls of the opening end and is provided with a clamping portion 3, and the two sides of the sealing strip 23 are respectively clamped on the corresponding clamping portions 3. Specifically, the mounting base 1 can be embedded around the wooden door leaf and door frame, and the openings of the first concave cavity 11 and the second concave cavity 12 of the mounting base 1 are both located on the outside.

[0020] As described above, the opening end cover of the first cavity 11 is provided with a cover plate 4, which can be used to cover the first fireproof expansion seal 21, making the entire fireproof and smokeproof sealing strip more beautiful.

[0021] As described above, the sealing strip 23 includes a sealing strip connecting portion 231 and an abutting strip 232 . Both sides of the sealing strip connecting portion 231 are respectively clamped on the corresponding clamping portions 3 . The sealing strip connecting portion 231 is arranged on the outer end surface of the sealing strip connecting portion 231 .

[0022] As described above, two abutment strips 232 are provided, and the two abutment strips 232 are parallel to each other and perpendicular to the outer end surface of the sealing strip connecting portion 231 .

[0023] Preferably, the sealing strip 23 and the cover plate 4 are both made of silicone rubber. Since silicone rubber has good heat resistance, it has a good insulating and sealing effect on isolating medium-temperature smoke, so that the sealing strip 23 and the cover plate 4 made of silicone can work for a long time at 180°C, can withstand several weeks or longer at a temperature slightly higher than 200°C, and can withstand high temperatures above 300°C instantly.

[0024] Preferably, the first fireproof expansion seal 21 and the second fireproof expansion seal 22 are both made of expanded graphite. Such a structural design allows the first fireproof expansion seal 21 and the second fireproof expansion seal 22 to expand to 20 times the size of the original body when a fire occurs outside at a temperature of about 200°, and the gap of the lower door seam can be completely sealed to prevent smoke and flames from escaping from the gap.

[0025] The above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
