DETAILED DESCRIPTION
[0030] See also Figure 1-7 The utility model provides a fire door with a double-layer sealed door frame, including a fire door body, which includes a frame body 1 and a door leaf 2. The door leaf 2 is rotatably mounted on the frame body 1, and the side surface and inner wall of the frame body 1 are respectively provided with a first side sealing groove and a first inner wall sealing groove, and the inner wall of the first side sealing groove and the inner wall of the first inner wall sealing groove are respectively installed with a first side sealing ring 3 and a first inner wall sealing ring 4, and the side surface and outer surface of the door leaf 2 are respectively provided with a second side sealing groove and a second outer wall sealing groove, and the inner wall of the second side sealing groove and the inner wall of the second outer wall sealing groove are respectively installed with a second side sealing ring 5 and a second outer wall sealing ring 6, an emergency escape opening 7 is provided on the door leaf 2, and an emergency escape blocking plate 8 is inserted in the emergency escape opening 7, and an anti-locking mechanism 13 is arranged between the frame body 1 and the door leaf 2.
[0031] By arranging the first side sealing ring 3 and the second side sealing ring 5 and the first inner wall sealing ring 4 and the second outer wall sealing ring 6 which cooperate with each other, a double sealing effect of the frame 1 and the door leaf 2 can be achieved, ensuring that the fire door body has good sealing characteristics when in use, and the anti-locking mechanism 13 provided can prevent the door leaf 2 from being accidentally locked during emergency escape. By arranging the emergency escape opening 7 in conjunction with the emergency escape blocking plate 8, the emergency escape blocking plate 8 can be detachably installed at the position of the emergency escape opening 7 through the locking plate 10, and the emergency mounting plates 11 provided on both sides of the emergency escape blocking plate 8 are used in conjunction with the mounting bolts 12. When the door leaf 2 is accidentally locked, the emergency escape blocking plate 8 can be opened for emergency escape, thereby further improving the safety of use, and emergency escape can be achieved both inside and outside the door leaf 2.
[0032] The emergency escape blocking plate 8 is provided with several cavities, and a sliding plate 9 is movably provided in the cavity. A locking plate 10 is fixedly installed on the surface of the sliding plate 9, and the locking plate 10 is slidably installed on the emergency escape blocking plate 8. The inner wall of the emergency escape opening 7 is provided with several locking grooves, and the locking plate 10 is inserted in the locking groove. An emergency mounting plate 11 is fitted at the position of the side of the emergency escape blocking plate 8 facing the cavity. Several mounting bolts 12 are threadedly installed on the emergency mounting plate 11 and are detachably connected to the emergency escape blocking plate 8 through the mounting bolts 12. Several emergency mounting plates 11 are symmetrically distributed on both sides of the door leaf 2. Locking is achieved by combining the lock plate 10 and the lock groove, and the mounting bolts 12 are used to achieve disassembly and locking of the emergency mounting plate 11. Both the inside and outside sides are provided to enable emergency escape both inside and outside.
[0033] An observation port is provided on the door leaf 2, and an explosion-proof window 14 is fixedly installed on the inner wall of the observation port. The observation port is used in conjunction with the explosion-proof window 14, and the situation can be checked through the explosion-proof window 14 when a fire occurs.
[0034] Several fixed guide rods 15 are fixedly installed on the inner wall of the cavity on the emergency escape blocking plate 8, and the sliding plate 9 is slidably installed on the outer surface of the fixed guide rods 15. The fixed guide rods 15 play a sliding support effect on the sliding plate 9, so that the sliding plate 9 has better stability during the sliding process and is not prone to tilting and shaking.
[0035] The outer sleeve of the fixed guide rod 15 is provided with a spring 16, and the two ends of the spring 16 are fixedly connected to the inner wall of the cavity and the surface of the sliding plate 9 respectively. The setting of the spring 16 can enable the lock plate 10 to be quickly inserted into the lock groove, thereby improving the installation convenience of the emergency escape blocking plate 8.
[0036] The anti-locking mechanism 13 includes a side plate 24 fixedly mounted on the inner wall of the frame 1, and a threaded rod 17 is threadedly mounted on the side plate 24. A handle and a rotating shaft 18 are fixedly mounted at both ends of the threaded rod 17. A linkage plate 19 is rotatably mounted on the end of the rotating shaft 18. A number of locking rods 20 are fixed on the side of the linkage plate 19, and a locking sleeve 21 is fixedly mounted on the side of the door leaf 2. The locking rod 20 and the locking sleeve 21 are used in conjunction with each other. The rotation of the threaded rod 17 drives the rotating shaft 18 to rotate, and can drive the linkage plate 19 to move horizontally, so that the locking rod 20 is inserted into the inside of the locking sleeve 21. In the initial state, the locking rod 20 is in a clamping position. At this time, when the door leaf 2 is rotated to close, it will not be closed tightly due to the existence of the locking rod 20, thereby effectively preventing the door leaf 2 from being accidentally locked.
[0037] A slider 22 is fixedly installed on the surface of the linkage plate 19, and a trapezoidal slide 23 is fixedly installed on the inner wall of the frame 1. The slider 22 is slidably installed on the outer surface of the trapezoidal slide 23. The trapezoidal slide 23 is used in conjunction with the slider 22 to provide sliding support for the linkage plate 19, thereby improving the movement smoothness of the linkage plate 19, thereby ensuring the stable cooperation between the locking rod 20 and the locking sleeve 21.
[0038] When in use, the locking rod 20 is in the clamping position when the door leaf 2 is open. At this time, the locking sleeve 21 will touch the locking rod 20 when the door leaf 2 is rotated to close. At this time, the door leaf 2 will not be closed tightly. The locking rod 20 and the locking sleeve 21 cooperate to prevent the door leaf 2 from being accidentally locked when closed. When the door leaf 2 needs to be closed, the threaded rod 17 is rotated to drive the rotating shaft 18 to drive the linkage plate 19 to move, and the linkage plate 19 drives the locking rod 20 to move, so that the locking rod 20 is out of the clamping position. At this time, the door leaf 2 can be completely closed and the door leaf 2 is closed tightly. After that, the threaded rod 17 is reversed again so that the locking rod 20 is reset and snapped into the locking sleeve 21. At this time, the locking rod 20 and the locking sleeve 21 have the effect of secondary locking of the door leaf 2. In case of fire, it can be checked through the explosion-proof window 14. When the door leaf 2 cannot be opened accidentally and emergency escape is required, the mounting bolts 12 are unscrewed to remove the emergency mounting plate 11. At this time, the sliding plate 9 can be operated. When the sliding plate 9 moves, it will drive the locking plate 10 out of the lock groove. At this time, the emergency escape blocking plate 8 is unlocked and can be removed. At this time, people can escape through the emergency escape opening 7.
