Description

Technical Field

[0001] This application relates to the field of emergency door window breaking devices, and in particular to an integrated triggering system for emergency door window breaking devices. Background Technology

[0002] Emergency doors are doors used for the rapid evacuation of people in emergency situations. They typically include emergency exits on airplanes and emergency doors on trains. Emergency door window breaking refers to breaking the doors and windows of a vehicle using specific tools or devices in an emergency to facilitate rapid escape. This measure is commonly used in public transportation vehicles such as buses and coaches to deal with emergencies such as fires and collisions. When installing a conventional emergency door, the door frame is installed in a suitable position, and the emergency door is rotatably connected to the inner wall of the door frame. A handle is installed on the surface of the emergency door to facilitate the opening and closing of the door.

[0003] Regarding the aforementioned technologies, the inventors believe that after installation, emergency doors are prone to handle damage due to prolonged use or improper use. Conventional emergency doors cannot provide a second escape route, making it difficult for them to quickly and effectively evacuate people in the event of an accident.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of emergency doors being unable to open due to damaged handles, this application provides an integrated triggering system for emergency door window breaking devices.

[0006] The integrated triggering system for the emergency door and window breaking device provided in this application adopts the following technical solution:

[0007] An integrated triggering system for an emergency door and window breaking device includes a door frame and a folding window. An emergency door is rotatably installed on the inner wall of the door frame, and the dimensions of the emergency door surface are adapted to the dimensions of the inner wall of the door frame. A handle is rotatably connected to the surface of the emergency door. Two connecting rings are rotatably installed at the bottom of the folding window. A fixing rod is slidably installed on the inner wall of the connecting ring, and the surface of the fixing rod is rotatably connected to the inner wall of the emergency door. The top of the folding window is rotatably installed on the inner wall of the emergency door, and the dimensions of the inner wall of the connecting ring are adapted to the dimensions of the surface of the fixing rod. The two connecting rings are symmetrically distributed about the folding window as an axis.

[0008] Preferably, the surface of the fixing rod is provided with a threaded groove, the inner wall of the threaded groove is threadedly installed with the inner wall of the connecting ring, the top of the fixing rod is rotatably connected to a connecting cylinder, the surface of the connecting cylinder is fixedly installed with the inner wall of the emergency door, and a rotating spring is fixedly installed on the inner wall of the connecting cylinder, one end of the rotating spring is fixedly connected to the top of the fixing rod.

[0009] Preferably, a limiting block is fixedly connected to the bottom end of the fixing rod, the center of the limiting block and the center of the fixing rod are on the same straight line, and a locking block is engaged on the surface of the limiting block, the surface of the locking block being rotatably installed with the inner wall of the emergency door.

[0010] Preferably, one end of the locking block is fixedly connected to a spring, and one end of the spring is fixedly installed to the inner wall of the emergency door.

[0011] Preferably, one end of the locking block is fixedly connected to a pull rope, the surface of the pull rope is slidably installed with the inner wall of the emergency door, and the end of the pull rope away from the locking block is fixedly installed with a pulling frame.

[0012] Preferably, a chassis is fixedly installed on the surface of the emergency door, and a cover is movably connected to the top of the chassis. The dimensions of the bottom of the cover are adapted to the dimensions of the top of the chassis, and one end of the cover is rotatably installed on the surface of the emergency door.

[0013] Preferably, the chassis and the inner wall of the cover are fixedly connected to two adsorption blocks, which are magnetic blocks, and the two adsorption blocks are axially symmetrically distributed.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a folding window inside an emergency door, two connecting rings are rotatably mounted at the bottom of the folding window. The inner wall of the connecting rings is connected to the surface of a fixed rod inside the emergency door, allowing the connecting rings to slide on the surface of the fixed rod to control the opening or closing of the folding window. This facilitates personnel access when the emergency door handle is damaged. The surface of the fixed rod has threaded grooves, the inner wall of which is threadedly connected to the inner wall of the connecting rings. A connecting cylinder is rotatably mounted at the top of the fixed rod, its inner wall fixed to the top of the fixed rod via a rotating spring. This allows the fixed rod to rotate, causing the connecting rings on the threaded groove surface to move up and down, facilitating the closing of the folding window during daily use. A limit block is installed at the bottom of the fixed rod, with a locking block on its surface. This locking block connects to the limit block to fix the bottom of the fixed rod, thus securing the rod. One end of the locking block is fitted with a spring, the other end of which is connected to the inner wall of the emergency door, allowing the spring to push the locking block, effectively improving its fixing effect. Compared to existing technologies, this significantly improves the safety of emergency door use.

[0016] 2. A pull rope can also be installed at one end of the locking block, with a pull frame at one end. This allows the pull frame to control the rope, pulling the locking block and causing the spring at one end of the locking block to retract, facilitating separation of the locking block from the limit block. This makes the device more convenient to use. A chassis is installed on the surface of the emergency door, with a cover connected to the top of the chassis. This cover and chassis together shield the surface of the pull frame, preventing external impurities from entering the emergency door. A magnetic adsorption block is installed between the chassis and the cover, allowing them to connect and making it easier to open the cover. This effectively improves the device's performance.

The inner wall of the connecting cylinder 13 is fixedly connected to the top of the fixing rod 6 by means of a rotating spring 14. The rotating spring 14 controls the rotation of the fixing rod 6, causing the connecting ring 5 on the surface of the threaded groove 7 to move up and down, which facilitates the control of the closing of the folding window 4 during daily use. A limit block 8 is installed at the bottom of the fixing rod 6. A locking block 9 is snapped onto the surface of the limit block 8. The locking block 9 is connected to the limit block 8 to fix the bottom of the fixing rod 6, thereby fixing the fixing rod 6. A spring 10 is installed at one end of the locking block 9. One end of the spring 10 is connected to the inner wall of the emergency door 2. The spring 10 pushes the locking block 9 to effectively improve the fixing effect of the locking block 9.

[0025] Reference Figure 3 - Figure 4 A pull rope 11 is installed at one end of the locking block 9, and a pull frame 12 is installed at one end of the pull rope 11. The pull rope 11 is controlled by the pull frame 12 to pull the locking block 9, causing the spring 10 at one end of the locking block 9 to retract, making it easier to separate the locking block 9 from the limit block 8, which is more convenient to use. A base 15 is installed on the surface of the emergency door 2, and a cover 16 is connected to the top of the surface of the base 15. The cover 16 and the base 15 cover the surface of the pull frame 12, preventing external impurities from entering the emergency door 2. A magnetic adsorption block 17 is installed between the base 15 and the cover 16, which connects the base 15 and the cover 16, making it more convenient to open the cover 16.

[0026] The implementation principle of the integrated triggering system for the emergency door window breaking device in this embodiment is as follows: A folding window 4 is installed inside the emergency door 2. Two connecting rings 5 ​​are rotatably installed at the bottom of the folding window 4. The inner wall of the connecting rings 5 ​​is flush with the surface of the fixing rod 6 inside the emergency door 2, allowing the connecting rings 5 ​​to slide on the surface of the fixing rod 6 to control the opening or closing of the folding window 4. This facilitates the opening of the folding window 4 for personnel access when the handle of the emergency door 2 is damaged. A threaded groove 7 is provided on the surface of the fixing rod 6, and the inner wall of the threaded groove 7 is threadedly connected to the inner wall of the connecting rings 5. A connecting cylinder 13 is rotatably installed on the top of the fixing rod 6, and the inner wall of the connecting cylinder 13 is rotatably connected to the connecting rings 5. The rotating spring 14 is fixedly connected to the top of the fixed rod 6 so that the rotation of the fixed rod 6 can be controlled by rotating the spring 14, so that the connecting ring 5 on the surface of the threaded groove 7 can move up and down, which is convenient for controlling the closing of the folding window 4 during daily use. The bottom end of the fixed rod 6 is equipped with a limit block 8, and a locking block 9 is engaged with the surface of the limit block 8 so that the bottom end of the fixed rod 6 can be fixed by connecting the locking block 9 with the limit block 8, thereby fixing the fixed rod 6. A spring 10 is installed at one end of the locking block 9, and one end of the spring 10 is connected to the inner wall of the emergency door 2 so that the locking block 9 can be pushed by the spring 10, which effectively improves the fixing effect of the locking block 9.

[0027] A pull rope 11 can also be installed at one end of the locking block 9. A pull frame 12 is installed at one end of the pull rope 11 so that the pull rope 11 can be controlled by the pull frame 12 to pull the locking block 9, causing the spring 10 at one end of the locking block 9 to retract, making it easier to separate the locking block 9 from the limit block 8. This makes it more convenient to use. A chassis 15 is installed on the surface of the emergency door 2. A cover 16 is connected to the top of the surface of the chassis 15 so that the cover 16 and the chassis 15 can cover the surface of the pull frame 12, preventing external impurities from entering the emergency door 2. A magnetic adsorption block 17 is installed between the chassis 15 and the cover 16 so that the chassis 15 and the cover 16 can be connected by the adsorption block 17, making it more convenient to open the cover 16.
