Description

Technical Field

[0001] The utility model relates to the technical field of special doors, in particular to a special door with high waterproof and fireproof performance. Background Art

[0002] Fire doors are doors that meet the requirements of fire resistance, stability, integrity, and thermal insulation for a specified period of time. They are fireproof partitions with a certain degree of fire resistance, installed within fire compartments, evacuation stairwells, vertical shafts, and other structures. They are specifically used to isolate fire sources in buildings and play a vital role in firefighting. In the event of a fire, fire doors provide escape opportunities. In addition to the functions of ordinary doors, fire doors also prevent the spread of fire and smoke, effectively preventing the spread of fire for a specified period of time and ensuring evacuation. Fire doors are also considered a type of specialty door.

[0003] At present, when special doors on the market are used, fireproof strips are added to the outside of the special doors, so that the subsequent fireproof strips can expand due to heat and thus block the smoke generated by the fire. At the same time, sealing materials are added to the outside of the special doors, so that the subsequent special doors can be waterproof. In actual use, most fireproof strips are bonded to the door leaves in the special doors. The fireproof strips will fall off when bonded to the door leaves for a long time. When the fireproof strips are subsequently bonded for the second time, the glue stains left on the original door leaves will affect the bonding strength of the subsequent fireproof strips, resulting in a reduced service life of the subsequently replaced fireproof strips.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The utility model provides a special door with high waterproof and fireproof performance. The technical solution is as follows:

[0023] A special door with high waterproof and fireproof performance includes a door frame 1, a door leaf 2 is hinged on the outer wall of the door frame 1, an outer wall of the door leaf 2 is provided with a mounting groove 3 on one side of the door frame 1, a groove 4 is provided inside the door leaf 2 at the mounting groove 3, a rotating rod 5 is provided inside the groove 4, one end of the rotating rod 5 is fixedly connected to a magnetic blocking plate 6, a spring 7 is provided between the magnetic blocking plate 6 and the groove 4, the outer wall of the rotating rod 5 is fixedly connected to a No. 1 magnetic block 8, the outer wall of the rotating rod 5 is fixedly connected to a No. 2 magnetic block 9 on one side of the No. 1 magnetic block 8, a locking rod 10 is provided inside the groove 4, and one end of the locking rod 10 is fixedly connected to a No. 3 magnetic block 11.

[0024] In a preferred embodiment, the end of the rotating rod 5 away from the magnetic blocking plate 6 passes through the outer wall of the door leaf 2 and the rotating rod 5 is rotatably connected to the door leaf 2, and one end of the locking rod 10 passes through the inside of the mounting groove 3. When the rotating rod 5 moves, the rotating rod 5 will move inside the groove 4, and at the same time, the rotating rod 5 can drive the magnetic blocking plate 6 to move.

[0025] In a preferred embodiment, the locking rod 10 is slidably connected to the door leaf 2, and a mounting plate 12 is slidably connected inside the mounting groove 3. A locking groove 13 is provided on the outer wall of the mounting plate 12, and one end of the locking rod 10 is slidably connected to the locking groove 13. When the third magnetic block 11 moves, the third magnetic block 11 can drive the locking rod 10 to move, so that the locking rod 10 moves inside the groove 4.

[0026] In a preferred embodiment, a fireproof strip 14 is bonded to the outer wall of the mounting plate 12, and the two ends of the spring 7 are fixedly connected to the outer wall of the magnetic blocking plate 6 and the inside of the groove 4 respectively. When the mounting plate 12 moves, the mounting plate 12 can move inside the mounting groove 3, making it easy for the mounting plate 12 to be removed from the inside of the mounting groove 3.

[0027] The working principle of the present invention is as follows: when the door leaf 2 is used for a long time, the fireproof strip 14 on the outer wall of the mounting plate 12 falls off, and the glue layer generated on the outer wall of the mounting plate 12 is inconvenient to clean, the rotating rod 5 is rotated at this time, and the rotating rod 5 rotates inside the groove 4. The rotating rod 5 also drives the magnetic resistance plate 6 to move, so that the magnetic resistance plate 6 rotates inside the groove 4. The magnetic resistance plate 6 also drives the spring 7 to move, so that the spring 7 is twisted. At the same time, the rotating rod 5 will drive the No. 1 magnetic block 8 to move in a small circular motion inside the groove 4. At the same time, the rotating rod 5 will drive the No. 2 magnetic block 9 to move in a circular motion inside the groove 4, so that the No. 1 magnetic block 8 is away from the No. 3 magnetic block 11, so that the No. 2 magnetic block 9 reaches the side of the No. 3 magnetic block 11, and the No. 2 magnetic block 9 and the No. 3 magnetic block 11 attract each other, so that the No. 3 magnetic block 11 moves toward the rotating rod 5. When the locking groove 13 is located on one side of the locking rod 10, the rotating rod 5 is released, and the torsion of the spring 7 resets the rotating rod 5, so that the No. 1 magnetic block 8 can return to the side of the No. 3 magnetic block 11. The No. 1 magnetic block 8 and the No. 3 magnetic block 11 repel each other, so that the No. 3 magnetic block 11 drives one end of the locking rod 10 to enter the inside of the locking groove 13, thereby making it easy to fix the position of the subsequent mounting plate 12, so that the glue layer retained by the subsequent fireproof strip 14 of the door leaf 2 can be dealt with in time, thereby not affecting the sealing and fitting of the subsequent fireproof strip 14.

[0028] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a technical solution: a special door with high waterproof and fireproof performance. A filling groove 15 is opened inside the door leaf 2, and the filling groove 15 is filled with perlite fireproof door core 16. When the rotating rod 5 moves, the rotating rod 5 will drive the magnetic blocking plate 6 to move, so that the magnetic blocking plate 6 can drive the spring 7 to move.

[0029] In a preferred embodiment, a waterproof layer 17 is provided inside the door leaf 2 on one side of the filling groove 15, and a locking mechanism 18 is provided on the outer wall of the door leaf 2. When the rotating rod 5 moves, the rotating rod 5 will drive the No. 1 magnetic block 8 to move, causing the No. 1 magnetic block 8 to move inside the groove 4.

[0030] The working principle of the present invention: the door frame 1 and the door leaf 2 are made of an alloy material of cold-rolled galvanized steel plate, the fireproof and heat-insulating material is a new type of perlite fireproof door core 16, and the sealing strips and sealing gaskets on the outside of the door frame 1 and the door leaf 2 are made of aging-resistant and high-temperature resistant rubber material. Through the special structural design and material selection of the two door leaves 2, the special door has the functions of waterproofing, fireproofing, airtightness, and impact resistance. In emergency situations such as fire or flood, it can effectively prevent the spread of fire or the intrusion of water, thereby ensuring the safety of personnel and equipment.
