Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a fireproof safety door for building fire escape routes. Background Technology

[0002] Fire doors are a special type of door used to prevent the spread of fire and protect the lives and property of people. Modern buildings, such as airports, hotels, large shopping malls, residential communities, and municipal buildings, are equipped with fire escape routes, and fire doors are installed at the safe entrances and exits of these routes. In the event of a fire, people close the fire doors to prevent the fire from spreading as they escape to a safe fire-prone area.

[0003] A search revealed a fireproof safety door for building fire escape routes (CN222066578U), comprising a door panel and a door frame, the door panel and the door frame being rotatably connected. The fireproof safety door also includes a sealing mechanism disposed in the gap between the bottom edge of the door panel and the door frame. The sealing mechanism includes a sealing drive assembly, a sealing strip, and an abutment plate. The sealing drive assembly is mounted on the door panel and is kinetically connected to the sealing plate. A through groove is formed on the end face of the door panel facing the door frame. The abutment plate is mounted on the door frame, and the sealing strip is correspondingly disposed with respect to the abutment plate.

[0004] The implementation of this technical solution has at least the following drawbacks: Although the utility model can guarantee the sealing performance of the sealing strip, the sealing strip on the fire door will wear down during frequent opening of the fire door, thus affecting the isolation effect on smoke. Furthermore, it is inconvenient for the sealing strip to expand after a fire, ensuring the sealing performance between the fire door and the door frame, which urgently needs improvement. Therefore, we propose a fire-resistant safety door for building fire escape routes. Utility Model Content

[0005] The purpose of this utility model is to provide a fireproof safety door for building fire escape routes, which solves the problem mentioned in the background art that the sealing strip on the fire door will wear down during the frequent opening of the fire door, thus affecting the isolation effect of smoke, and it is inconvenient for the sealing strip to expand after a fire, thus ensuring the sealing performance between the fire door and the door frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof safety door for building fire escape routes, comprising a fireproof door body, a sealing strip on the outer side of the fireproof door body, multiple slots on the inner side of the sealing strip, multiple fixing rods fixedly installed on the outer side of the fireproof door body, the fixing rods being equidistantly distributed, the fixing rods corresponding one-to-one with the slots, a storage shell fixedly installed at the upper end of the fixing rods, multiple discharge channels on the outer side of the storage shell, a thermal glass tube sealed in the inner cavity of the discharge channel, a protrusion fixedly connected to one side of the thermal glass tube, and the interior of the sealing strip being set as a cavity.

[0007] By adopting the above technical solution, when the sealing strip becomes worn, the groove on the sealing strip can be pulled to separate from the storage shell, and then the groove on the sealing strip can be inserted into the storage shell. The protrusion on the edge of the storage shell abuts against the inner wall of the groove, thereby limiting the installation of the sealing strip. This allows for convenient replacement of the sealing strip on the fire door after it becomes worn, thus ensuring the sealing strip's ability to isolate smoke. In the event of a fire, the heat-sensitive glass tube on the storage shell ruptures due to high temperature. At the same time, the expandable graphite inside the storage shell expands due to heat and is ejected from the storage shell. As the expandable graphite fills the inner cavity of the sealing strip, it causes the sealing strip to expand, thereby improving the sealing strip's ability to seal door gaps and prevent smoke.

[0008] Optionally, the discharge channel is configured as a rectangle and the discharge channel is arranged in a ring.

[0009] By adopting the above technical solution and setting up the discharge channel, it is convenient for the expandable graphite inside the storage shell to be ejected from the discharge channel.

[0010] Optionally, the size of the card slot is adapted to the outer dimensions of the storage housing, and the storage housing is movably connected to the card slot.

[0011] By adopting the above technical solution, the storage shell can be inserted into the slot, thereby limiting the installation of the sealing strip.

[0012] Optionally, the inner cavity of the storage shell is filled with expandable graphite.

[0013] By adopting the above technical solution, the expandable graphite can be heated and expanded, thereby causing the sealing strip to expand and deform.

[0014] Optionally, the size of the sealing strip is adapted to the edge size of the door frame of the fire door body.

[0015] By adopting the above technical solution, it is easy to ensure the sealing effect of the sealing strip on the fire door body.

[0016] Optionally, the bumps are disposed on the outside of the storage shell, and the bumps are distributed in a ring.

[0017] By adopting the above technical solution and setting the protrusions, it can be ensured that the storage shell can abut against the inner wall of the card slot.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution utilizes a fire door body, sealing strip, storage shell, protrusion, exhaust channel, and heat-sensitive glass tube. When the sealing strip becomes worn, the groove on the sealing strip can be pulled to separate it from the storage shell, and then the groove can be inserted into the storage shell. The protrusion on the edge of the storage shell abuts against the inner wall of the groove, thus securing the sealing strip. This allows for convenient replacement of the fire door's sealing strip after wear, ensuring its effectiveness in blocking smoke. In the event of a fire, the heat-sensitive glass tube on the storage shell ruptures due to high temperature. Simultaneously, the expandable graphite inside the storage shell expands and is ejected from the storage shell. The expansion of the expandable graphite fills the inner cavity of the sealing strip, causing it to expand further, thus enhancing its ability to seal door gaps and prevent smoke.

[0026] Please see Figure 1-4This utility model provides a technical solution: a fireproof safety door for building fire escape routes, including a fireproof door body 1, a sealing strip 2 on the outer side of the fireproof door body 1, multiple slots 21 on the inner side of the sealing strip 2, multiple fixing rods 22 fixedly installed on the outer side of the fireproof door body 1, and the fixing rods 22 are evenly distributed among each other, with each fixing rod 22 corresponding to a slot 21. A storage shell 23 is fixedly installed on the upper end of the fixing rod 22, and multiple discharge channels 3 are opened on the outer side of the storage shell 23. A thermal glass tube 4 is sealed and installed in the inner cavity of the discharge channel 3. The side is fixedly connected with a protrusion 24. The inside of the sealing strip 2 is set as a cavity. The inner cavity of the storage shell 23 is filled with expandable graphite. Through the setting of expandable graphite, the expandable graphite can be heated and expanded, thereby expanding and deforming the sealing strip 2. The size of the sealing strip 2 is adapted to the edge size of the door frame of the fire door body 1, so as to ensure the sealing effect of the sealing strip 2 on the fire door body 1. The protrusion 24 is set on the outside of the storage shell 23, and the protrusion 24 is distributed in a ring. Through the setting of the protrusion 24, it can be ensured that the storage shell 23 can abut against the inner wall of the slot 21.

[0027] The discharge channel 3 is rectangular and arranged in a ring shape. The arrangement of the discharge channel 3 facilitates the ejection of expandable graphite from the storage shell 23.

[0028] The size of the slot 21 is adapted to the outer size of the storage shell 23, and the storage shell 23 is movably connected to the slot 21. By setting the storage shell 23, the storage shell 23 can be inserted into the slot 21, thereby limiting the installation of the sealing strip 2.

[0029] During maintenance, when the sealing strip 2 becomes worn, pull the groove 21 on the sealing strip 2 to separate it from the storage shell 23, and then insert the groove 21 on the sealing strip 2 into the storage shell 23. The protrusion 24 on the edge of the storage shell 23 abuts against the inner wall of the groove 21, thereby limiting the installation of the sealing strip 2. This allows for convenient replacement of the sealing strip 2 on the fire door when it becomes worn, thus ensuring the sealing strip 2's effectiveness in isolating smoke. In the event of a fire, the heat-sensitive glass tube 4 on the storage shell 23 ruptures due to high temperature. At the same time, the expandable graphite inside the storage shell 23 expands due to heat and is ejected from the storage shell 23. As the expandable graphite expands and fills the inner cavity of the sealing strip 2, the sealing strip 2 expands, thereby improving the sealing strip 2's effectiveness in sealing door gaps and preventing smoke.
