[0028] like Figures 1-9 As shown, the utility model provides a fireproof window with a sealed flow-guiding structure, comprising: an outer fireproof window frame 1, on which a sealed flow-guiding mechanism 7 is provided;
[0029] The sealing guide mechanism 7 includes a guide hole 701, a U-shaped block 702, a connecting plate 703, two limiting holes 705, two threaded grooves 706 and a rectangular hole 712. The bottom of the connecting plate 703 is rotatably connected to a baffle 704 near the edge through a first hinge. The insides of the two threaded grooves 706 are both threadedly connected to hand screw bolts 707. The insides of the two limiting holes 705 are movably sleeved with fireproof strips 708. The tops of the two fireproof strips 708 are fixed with hollow blocks 709 near the edges. The insides of the two hollow blocks 709 are both provided with T-shaped rods 710. , an annular sealing strip 711 is bonded to the groove on the front surface of the baffle 704, the guide hole 701 is opened on the front surface of the inner wall of the groove on the outer surface of the outer fireproof window frame 1, the U-shaped block 702 is fixed to the groove on the outer surface of the outer fireproof window frame 1, the connecting plate 703 is installed on the rear surface of the outer fireproof window frame 1 near the top position, the front surface of the baffle 704 is in contact with the surface of the outer fireproof window frame 1, the two limiting holes 705 are both opened on the front surface of the outer fireproof window frame 1, the two threaded grooves 706 are both opened on the front surface of the outer fireproof window frame 1, and the same two fireproof strips 708 The front surfaces of the two hand-tightened bolts 707 are fixed to the surfaces of the two T-shaped rods 710 respectively. The front surface of the annular sealing strip 711 contacts the front surface of the outer fireproof window frame 1. The rectangular hole 712 is opened on the rear surface of the inner wall of the outer surface groove of the outer fireproof window frame 1. The annular sealing strip 711 is at the exit position of the rectangular hole 712. The two through holes of the outer fireproof window frame 1 are connected to the inner fireproof window frame 2 through the second hinge. The outer surfaces of the two inner fireproof window frames 2 are bonded with fireproof sealing rings 3. The two fireproof window frames 2 are connected to the outer surfaces of the two inner fireproof window frames 2. The outer wall of the sealing ring 3 is in contact with the inner walls of the two through holes of the outer fireproof window frame 1 respectively. Two rectangular rings 4 are fixed inside each inner fireproof window frame 2. The four rectangular rings 4 are divided into two groups. The opposite side of each group of rectangular rings 4 is provided with fireproof glass 5. The two fireproof glasses 5 are respectively located inside the two inner fireproof window frames 2. Manual locks 6 are installed on the two inner fireproof window frames 2. The clamping ends of the two manual locks 6 are movable through the inner walls of the two fireproof sealing rings 3 respectively. The clamping ends of the two manual locks 6 are respectively located inside the lock grooves of the inner walls of the two through holes of the inner fireproof window frame 2.
[0030] The effect achieved is that when it is necessary to open the fireproof window, the handle of one of the manual locks 6 is directly turned to move the clamping end of the manual lock 6 out of the corresponding lock groove on the outer fireproof window frame 1, and then the corresponding inner fireproof window frame 2 is rotated. At this time, the rotating inner fireproof window frame 2 can drive the fireproof sealing ring 3, rectangular ring 4, manual lock 6 and fireproof glass 5 connected thereto to rotate. When the inner fireproof window frame 2 is rotated to a suitable angle, the above steps are repeated to rotate the other inner fireproof window frame 2 to a suitable angle. When both inner fireproof window frames 2 are rotated When the fireproof window is opened, the fireproof window 708 is opened. When a fire occurs indoors and the fireproof window cannot be opened, the people trapped in the room can first bend and deform one of the fireproof strips 708 until the corresponding hollow block 709 is separated from the corresponding T-shaped rod 710, and then remove the corresponding hand-tightening bolt 707 from the inside of the corresponding threaded groove 706. Then, repeat the above steps to remove the other hand-tightening bolt 707 from the inside of the corresponding threaded groove 706. After that, with the cooperation of the two limiting holes 705, the two fireproof windows can be moved at the same time. The two fireproof strips 708 that move horizontally will drive the baffle 704 connected thereto to rotate under the cooperation of the connecting plate 703 and the first hinge. At this time, the rotating baffle 704 will also drive the annular sealing strip 711 connected thereto to rotate. When the two hollow blocks 709 are moved to a point where they cannot move, the two threaded grooves 706 and the two hand-tightening bolts 707 are directly used to fix the two hollow blocks 709.

When there is no fire indoors and a fire occurs outdoors, at this time, with the cooperation of the non-rotating annular sealing strip 711, the high temperature gas or smoke outside can be prevented from entering the interior of the rectangular hole 712 through the gap between the external fireproof window frame 1 and the baffle 704, thereby preventing the high temperature gas or smoke outside from entering the room.
[0031] Working principle: When it is necessary to open the fireproof window, just turn the handle of one of the manual locks 6 to move the clamping end of the manual lock 6 out of the corresponding lock slot on the outer fireproof window frame 1, and then turn the corresponding inner fireproof window frame 2. At this time, the rotating inner fireproof window frame 2 can drive the fireproof sealing ring 3, rectangular ring 4, manual lock 6 and fireproof glass 5 connected thereto to rotate. When the inner fireproof window frame 2 is rotated to a suitable angle, repeat the above steps and rotate the other inner fireproof window frame 2 to a suitable angle. When both inner fireproof window frames 2 are rotated to the closed position, When the angle is appropriate, the fireproof window opening operation is completed. When a fire occurs indoors and the fireproof window cannot be opened, the people trapped in the room can first bend and deform one of the fireproof strips 708 until the corresponding hollow block 709 is separated from the corresponding T-shaped rod 710, and then remove the corresponding hand-tightening bolt 707 from the inside of the corresponding threaded groove 706, and then repeat the above steps to remove the other hand-tightening bolt 707 from the inside of the corresponding threaded groove 706. Then, with the cooperation of the two limiting holes 705, move the two fireproof windows at the same time. The two fireproof strips 708 that move horizontally will drive the baffle 704 connected thereto to rotate under the cooperation of the connecting plate 703 and the first hinge. At this time, the rotating baffle 704 will also drive the annular sealing strip 711 connected thereto to rotate. When the two hollow blocks 709 are moved to a point where they cannot move, the two threaded grooves 706 and the two hand-tightening bolts 707 are directly used to fix the two hollow blocks 709. At this time, the two fireproof strips 708 will be fixed, that is, the baffle 704 will be fixed after rotation. Fixed, the high temperature and smoke in the room can be discharged from the room through the cooperation of the guide hole 701, the rectangular hole 712 and the space formed by the groove on the outer surface of the external fireproof window frame 1 and the U-shaped block 702, which is convenient for the subsequent evacuation and rescue work of personnel. When there is no fire indoors and a fire occurs outdoors, at this time, with the cooperation of the non-rotating annular sealing strip 711, the high temperature gas or smoke outside can be prevented from entering the interior of the rectangular hole 712 through the gap between the external fireproof window frame 1 and the baffle 704, thereby preventing the high temperature gas or smoke outside from entering the room.
[0032] The fireproof strip 708 is a fireproof strip that can be bent and deformed and has a certain elasticity and toughness. The annular sealing strip 711 is a fireproof expansion sealing strip. The first hinge and the second hinge are both commonly used parts in reality.
