Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically to an aluminum alloy edge sealing structure for fire doors. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire compartments, evacuation stairwells, vertical shafts and other fire-resistant partitions. Fire doors need to be sealed at the edges to prevent the corners of the fire door from being affected by fire. However, the existing edge sealing uses a wooden structure, which has poor fire resistance and is inconvenient to install, so it has the disadvantage of being inconvenient to use.

[0003] According to the publication number (CN219138860U), an aluminum alloy edge sealing structure for fire doors is disclosed, including a fire door. The front end of the fire door is fixedly connected to an upper protective aluminum alloy and a lower protective aluminum alloy. Both ends of the upper and lower protective aluminum alloys are provided with several second connecting holes. The front ends of the upper and lower protective aluminum alloys are provided with three first connecting holes. The lower part of the front end of the upper protective aluminum alloy is provided with a first connecting groove. The rear inner wall of the first connecting groove is provided with two third connecting holes. The upper end of the lower protective aluminum alloy is fixedly connected to a first connecting plate.

[0004] The implementation of this technical solution has at least the following drawbacks: although this utility model can seal the edges of fire doors, the installation is too cumbersome and it is inconvenient to mitigate fires near the fire door in the event of a fire, thus requiring improvement. Therefore, we propose an aluminum alloy edge sealing structure for fire doors. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum alloy edge sealing structure for fire doors, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy edge sealing structure for fire doors, comprising a fire door body, a receiving groove on one side of the fire door body, a positioning groove on the other side of the receiving groove, an edge sealing shell on the outer side of the fire door body, a positioning rod fixedly installed on the inner side of the edge sealing shell, a slot on the outer side of the positioning rod, a retaining strip on one side of the inner cavity of the receiving groove, the retaining strip being movably connected to the retaining groove, a screw rod penetrating through the middle of one side of the fire door body, a winding drum fixedly installed in the middle of the screw rod, a pull rope wound around the outer wall of the winding drum, the other end of the pull rope being fixedly connected to the outer side of the retaining strip, and a positioning block fixedly installed on the inner side of the edge sealing shell.

[0007] By adopting the above technical solution, the winding drum on the screw can release the wound pull rope. Due to the spring's elasticity, the return spring drives the locking strip to move outward, causing the locking strip to engage with the locking groove, thereby limiting the position of the inserted positioning rod. This allows for quick installation and positioning of the edge sealing shell. In the event of a fire, when the temperature near the fire door body exceeds a threshold, the fire-fighting glass bulb on the edge sealing shell will rupture upon reaching the required temperature. Then, the powdered extinguishing agent filled inside the edge sealing shell will be sprayed out, thereby mitigating the fire near the fire door body and improving the fire resistance of the fire door.

[0008] Optionally, a return spring is fixedly installed on one side of the card strip, and the other end of the return spring is fixedly connected to the inner wall of the receiving groove.

[0009] By adopting the above technical solution and setting a reset spring, the card strip can be driven to reset, thereby causing the card strip to be inserted into the card slot.

[0010] Optionally, a plurality of fire-fighting glass spheres are sealed and installed on the outer side of the sealing shell, and the fire-fighting glass spheres are distributed at equal intervals.

[0011] By adopting the above technical solution and setting the fire-fighting glass bulb, the powder extinguishing agent inside the sealing shell can be sprayed out during a fire.

[0012] Optionally, the size of the positioning block is adapted to the size of the positioning groove, and the positioning block and the positioning groove are movably connected.

[0013] By adopting the above technical solution, the position of the edge sealing shell can be limited by the cooperation of the positioning block and the positioning groove.

[0014] Optionally, the inner cavity of the sealing shell is filled with powdered fire extinguishing agent.

[0015] By adopting the above technical solutions, it is easier to mitigate fires near the main body of the fire door.

[0016] Optionally, the size of the positioning rod is adapted to the size of the receiving groove, and the positioning rod is movably connected to the receiving groove.

[0017] By adopting the above technical solution, the installation of the edge sealing shell can be limited by the cooperation of the positioning rod and the receiving groove.

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

[0019] This technical solution, through the design of a fire door body, screw, winding drum, edge sealing shell, locking strip, return spring, positioning block, and fire-resistant glass bulb, allows the winding drum on the screw to release the wound pull rope. Due to the spring's resilience, the return spring moves the locking strip outward, engaging it with the locking slot and thus limiting the position of the inserted positioning rod. This enables rapid installation and positioning of the edge sealing shell. In the event of a fire, when the temperature near the fire door body exceeds a threshold, the fire-resistant glass bulb on the edge sealing shell will rupture upon reaching the required temperature, releasing the powdered extinguishing agent inside the edge sealing shell. This mitigates the fire near the fire door body, thereby improving the fire-resistant effect of the fire door. Attached Figure Description

[0025] Please see Figure 1-3This utility model provides a technical solution: an aluminum alloy edge sealing structure for fire doors, including a fire door body 1, a receiving groove 11 on one side of the fire door body 1, a positioning groove 12 on the other side of the receiving groove 11, an edge sealing shell 2 on the outer side of the fire door body 1, a positioning rod 21 fixedly installed on the inner side of the edge sealing shell 2, a slot 22 on the outer side of the positioning rod 21, a retaining strip 23 on one side of the inner cavity of the receiving groove 11, the retaining strip 23 being movably connected to the slot 22, a screw 13 penetrating through the middle of one side of the fire door body 1, a winding drum 14 fixedly installed in the middle of the screw 13, and a pull rope 3 wound around the outer wall of the winding drum 14. The other end of the pull rope 3 is fixedly connected to the outside of the clip 23. A positioning block 25 is fixedly installed on the inside of the edge sealing shell 2. The size of the positioning block 25 is adapted to the size of the positioning groove 12, and the positioning block 25 is movably connected to the positioning groove 12. By cooperating with the positioning block 25 and the positioning groove 12, the position of the edge sealing shell 2 can be limited. The inner cavity of the edge sealing shell 2 is filled with powdered fire extinguishing agent, which is convenient for mitigating fires near the fire door body 1. The size of the positioning rod 21 is adapted to the size of the receiving groove 11, and the positioning rod 21 is movably connected to the receiving groove 11. By cooperating with the positioning rod 21 and the receiving groove 11, the installation of the edge sealing shell 2 can be limited.

[0026] A reset spring 24 is fixedly installed on one side of the locking strip 23, and the other end of the reset spring 24 is fixedly connected to the inner wall of the receiving groove 11. By setting the reset spring 24, the locking strip 23 can be driven to reset, thereby causing the locking strip 23 to be locked into the locking groove 22.

[0027] Multiple fire-fighting glass balls 4 are sealed and installed on the outer side of the sealing shell 2, and the fire-fighting glass balls 4 are evenly distributed. Through the arrangement of the fire-fighting glass balls 4, the powder extinguishing agent inside the sealing shell 2 can be sprayed out in the event of a fire.

[0028] During installation, first insert the positioning block 25 on the edge sealing shell 2 into the positioning groove 12, then rotate the screw 13 counterclockwise to release the wound pull rope 3 from the winding drum 14 on the screw 13. Due to the spring's elasticity, the return spring 24 drives the locking strip 23 to move outward, so that the locking strip 23 engages with the locking groove 22, thereby limiting the position of the inserted positioning rod 21. This allows for quick installation and positioning of the edge sealing shell 2. In the event of a fire, when the temperature near the fire door body 1 exceeds the threshold, the fire-fighting glass bulb 4 on the edge sealing shell 2 will rupture after reaching the temperature. Then, the powder extinguishing agent filled inside the edge sealing shell 2 will be sprayed out, thereby mitigating the fire near the fire door body 1 and improving the fireproof effect of the fire door.
