Technical Field

[0001] The utility model relates to the field of fireproof doors, in particular to a fireproof door capable of blocking smoke. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with a certain degree of fire resistance, installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.

[0003] Fire doors in related technologies usually include door frames and door panels. When a fire occurs indoors, firefighters need to open the fire doors to extinguish the fire. However, if the fire spreads to the vicinity of the fire door, the firefighters will be threatened if they rashly open the fire door, which needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fire door that can block smoke, so that firefighters can perform firefighting operations outside the fire door to ensure the personal safety of firefighters.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a fireproof door capable of blocking smoke, comprising a door frame and a door panel, wherein the door panel is provided with an observation port and a fire port, wherein the fire port is located below the observation port, and the two ends of the observation port are respectively inlaid with fireproof observation glass, and the two ends of the fire port are respectively inlaid with fireproof firefighting glass, and the fireproof observation glass and the fireproof firefighting glass are respectively sealed and fixedly connected to the door panel by fireproof glue.

[0006] In a preferred example, the utility model can be further configured as follows: the inner wall of the fire port is conical and matches the fire hose.

[0007] In a preferred example, the utility model can be further configured as follows: a plurality of elastic sealing rings are fixedly connected to the inner wall of the fire opening along its circumference, and the plurality of sealing rings are arranged at equal intervals along the axial direction of the fire opening.

[0008] In a preferred example, the utility model can be further configured as follows: the side wall of the door panel is fixedly connected with an annular sealing portion along its circumference, and the sealing portion can be tightly abutted against the inner wall of the door frame.

[0009] In a preferred example, the utility model can be further configured as follows: the sealing portion includes an elastic sealing plate and fireproof rubber, and the fireproof rubber is coated on the sealing plate.

[0010] In a preferred example, the utility model can be further configured as follows: the sealing plate is made of spring steel material, the cross section of the sealing plate is Ω-shaped, and the fireproof rubber is coated on the outer wall of the sealing plate.

[0011] In a preferred example, the utility model can be further configured as follows: a sealing groove matching the sealing plate is provided on the inner side wall of the door frame.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. By setting up observation ports and fire ports on the door panels, firefighters can observe the fire outside the fire door, break the fireproof glass with a fire hose, and then insert the fire hose into the fire port to extinguish the fire. This design enables firefighters to carry out firefighting operations outside the fire door, reducing the risk of injury to firefighters and ensuring their personal safety;

[0014] 2. By providing a sealing portion on the door panel that can closely abut against the door frame, the sealing effect between the door panel and the door frame is improved to achieve smoke isolation and reduce the risk of smoke spreading outward. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 , Figure 2 A fire door capable of blocking smoke comprises a door frame 1 and a door panel 2. The door panel 2 is provided with an observation port 3 and a fire port 4, and the fire port 4 is located below the observation port 3. Fireproof observation glass 5 is inlaid at the two ends of the observation port 3, which can not only achieve fire prevention, but also facilitate firefighters to check the fire outside the fire door.

[0021] Reference Figure 1 , Figure 2The two ends of the fire-fighting opening 4 are respectively inlaid with fire-proof fire-fighting glass 6 to achieve fire-proof and blocking effects. At the same time, the fire-proof observation glass 5 and the fire-proof fire-fighting glass 6 are respectively connected to the door panel 2 by fire-proof glue to improve the sealing effect.

[0022] By arranging the observation port 3 and the fire port 4 on the door panel 2, firefighters can observe the fire situation outside the fire door, and use the fire hose to smash the fireproof glass 6, and then insert the fire hose into the fire port 4 to extinguish the fire. This design enables firefighters to carry out firefighting operations outside the fire door, reduce the risk of injury to firefighters, and ensure the personal safety of firefighters.
