[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the present invention is not limited to the following specific embodiments.
[0037] refer to Figure 1 A detachable fireproof window includes an outer fixed frame 11, an inner movable frame 21 and a glass window 22.
[0038] refer to Figure 2 and Figure 3 A support mechanism is provided between the outer fixed frame 11 and the inner movable frame 21. The support mechanism includes an upper connecting rod 41 and a lower connecting rod 42. The ends of the upper connecting rod 41 are rotatably connected to the outer fixed frame 11 and the inner movable frame 21, respectively. The lower connecting rod 42 is located below the upper connecting rod 41, and the ends of the lower connecting rod 42 are rotatably connected to the outer fixed frame 11 and the inner movable frame 21, respectively. The outer fixed frame 11 is provided with a through-hole 12, and the inner movable frame 21 blocks the through-hole 12. The glass window 22 is mounted on the inner movable frame 21. A limiting surface 23 is provided on one side of the inner movable frame 21. A sealing ring 13 located within the through-hole 12 is fixedly connected to the outer fixed frame 11. The sealing ring 13 is in contact with the limiting surface 23, thereby enhancing the sealing effect between the inner movable frame 21 and the outer fixed frame 11. The outer fixed frame 11 is provided with a movable groove 43 for accommodating the upper connecting rod 41 and the lower connecting rod 42.
[0039] refer to Figures 1 to 4The outer fixed frame 11 is provided with an upper locking hole 14 and a lower locking hole 15, and the inner movable frame 21 is slidably connected to an upper locking pin 24 and a lower locking pin 25, which respectively cooperate with the upper locking hole 14 and the lower locking hole 15. The upper locking pin 24 is fixedly connected to a driven rack 31, and the inner movable frame 21 is rotatably connected to a gear 32. The inner movable frame 21 is slidably connected to a driving block 34, and the driving block 34 is fixedly connected to an active rack 33. The active rack 33 and the driven rack 31 are respectively engaged with the two sides of the gear 32. The inner movable frame 21 is rotatably connected to a rotating shaft 35, and the rotating shaft 35 is fixedly connected to a rocker arm 36. A first connecting rod 37 is provided between the rocker arm 36 and the driving block 34, and the two ends of the first connecting rod 37 are rotatably connected to the rocker arm 36 and the driving block 34 respectively. The rotating shaft 35 is fixedly connected to a handle 38, and the provision of the handle 38 facilitates the rotation of the driving shaft 35. The inner movable frame 21 is provided with a receiving slot 26 for accommodating the handle 38. A glass demolition plate 27 is fixedly connected to the inner movable frame 21, blocking the receiving slot 26. A second connecting rod 39 is provided between the rocker arm 36 and the lower locking pin 25. The ends of the second connecting rod 39 are respectively connected to the rocker arm 36 and the lower locking pin 25 for rotation.
[0040] The outer fixed frame 11 is fixedly connected to a stopper 16 located below the through-opening 12. Stopper 16 is aligned with stopper surface 23. A stopper hole 17 is provided above the stopper 16 on the outer fixed frame 11. This hole 17 engages with an upper locking pin 24. The distance between stopper hole 17 and the stopper pin is equal to the distance between the upper locking hole 14 and the sealing ring 13. The surface of stopper 16 closest to the inner movable frame 21 is parallel to the horizontal plane.
[0041] The inner movable frame 21 is connected via an upper connecting rod 41 and a lower connecting rod 42, allowing it to flip and move on the outer fixed frame 11. When the inner movable frame 21 blocks the through-opening 12, the inner movable frame 21 is in a vertical position and parallel to the outer fixed frame 11, thereby effectively blocking the through-opening 12 and preventing flames and smoke from passing through the gap between the inner movable frame 21 and the outer fixed frame 11 during a fire. When personnel encounter an emergency and need to pass through the through-opening 12, they pull the inner movable frame 21 away from the sealing ring 13, causing it to move the glass window 22 out of the through-opening 12, thereby achieving the function of disassembling the inner movable frame 21 and the glass window 22. During the movement of the inner movable frame 21, the upper connecting rod 41 and the lower connecting rod 42 limit the direction of movement and the angle of rotation of the inner movable frame 21, allowing the inner movable frame 21 to move to engage with the limit block 16. The limit block 16 blocks the inner movable frame 21 from below, allowing the inner movable frame 21 to move downward to between the limit block 16 and the through-opening 12. The inner movable frame 21 is in a horizontal state when engaged with the limit block 16. When climbing up the through-opening 12, a person can step on the inner movable frame 21 engaged with the limit block 16, using the inner movable frame 21 as a step for leverage, facilitating escape through the through-opening 12.
[0042] This embodiment has the following advantages:
[0043] When the inner movable frame 21 and the glass window 22 are moved out of the through-opening 12, the upper connecting rod 41 and the lower connecting rod 42 limit the movement direction and the tilting angle of the inner movable frame 21, thereby preventing the inner movable frame 21 from rolling freely outward. When the inner movable frame 21 is tilted out, the person can anticipate the movement direction of the inner movable frame 21, thereby preventing the person from being hit by the inner movable frame 21 due to failure to dodge in time. The inner movable frame 21 is limited by the limit block 16, thereby preventing the limit block 16 from moving too far and colliding with the person, thereby improving safety and achieving a better safety advantage.
[0044] After the inner movable frame 21 moves out of the through-opening 12 and engages with the limit block 16, the inner movable frame 21 is in a horizontal state and is located between the through-opening 12 and the limit block 16. When people climb up the through-opening 12, they can use the horizontal inner movable frame 21 as a step, which facilitates leverage and makes it easier for people to climb up the through-opening 12 to escape.
[0045] When the inner movable frame 21 blocks the through-opening 12, the upper locking pin 24 and the lower locking pin 25 are driven to slide on the inner movable frame 21, so that the upper locking pin 24 and the lower locking pin 25 are respectively inserted into the upper locking hole 14 and the lower locking hole 15, thereby realizing the function of locking the inner movable frame 21 at the through-opening 12.
[0046] The driving block 34 slides on the inner movable frame 21 , and drives the upper locking pin 24 to move through the active rack 33 , the driven rack 31 and the gear 32 , thereby driving the upper locking pin 24 to slide on the inner movable frame 21 .
[0047] The driving shaft 35 rotates, and the rotating shaft 35 drives the driving block 34 to move through the rocker arm 36 and the first connecting rod 37 , thereby driving the driving block 34 to slide on the inner movable frame 21 .
[0048] The handle 38 is received in the receiving groove 26 and then blocked by the demolition plate 27, thereby preventing objects from colliding with the handle 38 and causing the handle 38 to rotate accidentally, thereby improving reliability. When the handle 38 needs to be rotated, the demolition plate 27 is smashed, allowing the handle 38 to rotate within the receiving groove 26.
[0049] During the rotation of the rotating shaft 35 and the rocker arm 36 , the lower locking pin 25 is driven to move via the second connecting rod 39 , thereby driving the lower locking pin 25 to slide on the inner movable frame 21 .
[0050] When the inner movable frame 21 is engaged with the limit block 16, the upper locking pin 24 is driven to be inserted into the limit hole 17, thereby locking the inner movable frame 21 and keeping the inner movable frame 21 engaged with the limit block 16. When a person climbs up the through opening 12 on the inner movable frame 21, the inner movable frame 21 remains stable, thereby improving safety.
[0051] The movable groove 43 accommodates the upper connecting rod 41 and the lower connecting rod 42 to prevent objects from colliding with the upper connecting rod 41 and the lower connecting rod 42, thereby improving the reliability of the upper connecting rod 41 and the lower connecting rod 42.
[0052] The side surface on which the limiting block 16 is in contact with the limiting surface 23 is parallel to the horizontal plane, and the inner movable frame 21 is also in a horizontal state when it is engaged and in contact with the limiting block 16, so that the inner movable frame 21 can be in a horizontal state and remain stable when it is engaged with the limiting block 16, thereby improving the stability of the inner movable frame 21.
[0053] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
