Description
Technical Field
[0001] This utility model belongs to the field of escape door technology, specifically referring to an emergency evacuation escape door that can be automatically or manually operated. Background Technology
[0002] In crowded public places such as shopping malls, schools, office buildings, and hospitals, emergency evacuation exits are key facilities for ensuring the safety of people's lives.
[0003] Most existing emergency evacuation doors adopt traditional swing doors or sliding doors. Traditional swing doors require a large space to open, and in crowded emergencies, they may not be able to open fully due to insufficient space, resulting in low evacuation efficiency and even stampedes. While sliding doors save space, they suffer from problems such as uneven sliding and poor sealing, failing to effectively block smoke and harmful gases generated during a fire. Furthermore, the evacuation passage of a single sliding door is limited, making it difficult to meet the needs of rapid evacuation of large numbers of people. In addition, some existing escape doors lack automatic sensor opening functions, relying too much on manual operation. In the event of a power outage or when people are panicked and unable to operate them properly, this will seriously affect the escape efficiency. Therefore, there is an urgent need for a more efficient, safe, and reliable emergency evacuation door. Utility Model Content
[0004] To address the aforementioned challenges, this invention provides an emergency evacuation door that can be opened automatically or manually. The two sets of first door panels can be rotated to open, and the two sets of second door panels can be slid or rotated to open, greatly expanding the evacuation route and enabling the evacuation of more people in a short time. The dual-mode design of automatic and manual operation adapts to various emergency situations. The second door panels' ability to both slide and rotate to open, along with the reliable fixing and re-sliding function after closing, enhances the flexibility and convenience of using the escape door.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: An emergency evacuation escape door that can be operated automatically or manually includes a door frame, a first door leaf, and a second door leaf. Two sets of the first and second door leaves are arranged opposite each other. The two sets of first door leaves are located at opposite ends of the door frame. The first door leaf is rotatably connected to the door frame via a door leaf shaft. A groove is provided on the bottom wall of the door frame. The second door leaf is slidably mounted within the groove via a door leaf shaft. A drive swing mechanism is provided in the top wall of the door frame. The drive swing mechanism is drively connected to the second door leaf. The two sets of second door leaves can slide open or close in opposite directions along the groove via the drive swing mechanism, while simultaneously providing a push to the second door leaf. The second door can also be opened by rotating the door leaf shaft. A sensor probe and a slot are provided on the bottom of the top wall of the door frame. A sensor contact point and an elastic locking shaft are provided on the top wall of the first door. The sensor probe and the sensor contact point are configured to cooperate, and the slot and the elastic locking shaft are configured to cooperate. When the first door is pushed open, the elastic locking shaft retracts. When the first door is closed, the elastic locking shaft extends into the slot, and the first door is locked. The cooperation between the sensor contact point and the sensor probe on the first door makes it automatically de-energized when the first door is rotated open and automatically closed when the first door is closed. The two sets of second door leaves in the middle can slide freely in the track and can be pushed open by rotating the door leaf shaft.
[0006] As a preferred technical solution of this utility model, the driving swing mechanism includes a slide rail and a pulley seat. The slide rail is horizontally fixed inside the top wall of the door frame, and two sets of pulley seats are slidably connected to the slide rail. The two sets of pulley seats are respectively connected to two sets of second door leaves.
[0007] As a preferred embodiment of this utility model, the drive swing mechanism further includes a motor, a belt tensioner, and a drive belt. The motor is fixedly installed inside the top wall of the door frame. Two sets of belt tensioners are rotatably installed opposite each other inside the top wall of the door frame. The drive belt is wound between the two sets of belt tensioners. A transmission belt is wound between the output end of the motor and the rotating shaft of the belt tensioner. The motor drives the belt tensioner to rotate through the transmission belt, and the drive belt on the belt tensioner moves accordingly. The drive belt drives the two sets of second door panels to slide in opposite directions through connecting block one and connecting block two, respectively, ensuring the coordination and consistency of the opening actions of the two sets of second door panels, ensuring that the evacuation passage can be opened evenly and quickly, and improving evacuation efficiency.
[0008] As a preferred embodiment of the present invention, a connecting block 1 is fixedly connected to one group of the pulley seats, and the connecting block 1 is connected to the upper half of the drive belt. A connecting block 2 is fixedly connected to the other group of the pulley seats, and the connecting block 2 is connected to the lower half of the drive belt.
[0009] As a preferred technical solution of this utility model, a buckle is provided on the second door leaf, and a fixed connector is provided under the top wall of the door frame. The fixed connector is correspondingly and adapted to the buckle. When a push force is applied to the second door leaf, the second door leaf is opened by rotating the door leaf shaft. At this time, the buckle is separated from the fixed connector. After the second door leaf is rotated back to the initial state, the buckle is engaged with the fixed connector, and the pulley seat can drive the second door leaf to slide in the groove again.
[0010] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:
[0011] 1. The two sets of first doors can be opened by rotation, and the two sets of second doors can be opened by sliding or rotating, which greatly widens the evacuation passage. Compared with traditional escape doors, more people can be evacuated in a short time, effectively reducing the probability of stampede accidents and meeting the needs of rapid evacuation of large numbers of people in emergency situations.
[0012] 2. The first door leaf is secured by a spring-loaded hinge and a slot to ensure a stable closure under normal conditions. The sensor contact point works with the sensor probe to automatically cut off power when the first door leaf is opened and automatically close when it is closed, avoiding potential electrical safety hazards and ensuring normal operation. The second door leaf's latch works with the fixed connector to prevent accidental operation in non-emergency situations, ensuring the stability and safety of the door.
[0013] 3. The automatic and manual dual-mode design adapts to various emergency situations. The second door can be opened by sliding or rotating, and it can be reliably fixed and slid again after closing, which enhances the flexibility and convenience of using the escape door.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.
[0026] like Figures 1-9As shown, this utility model provides an automatic or manual emergency evacuation escape door, including a door frame 1, a first door leaf 2, and a second door leaf 3. Two sets of first door leaves 2 and 3 are arranged opposite each other. The two sets of first door leaves 2 are located at opposite ends of the door frame 1. The first door leaves 2 are rotatably connected to the door frame 1 via a door leaf shaft 5. A groove 4 is provided on the bottom wall of the door frame 1. The second door leaf 3 is slidably disposed within the groove 4 via a door leaf shaft 6. A drive swing mechanism 7 is provided in the top wall of the door frame 1. The drive swing mechanism 7 is drively connected to the second door leaf 3. The two sets of second door leaves 3 can slide open or close in opposite directions along the groove 4 via the drive swing mechanism 7, while simultaneously providing a thrust to the second door leaf 3. The second door leaf 3 can also be opened or closed by... The door leaf 2 is opened by rotating the pivot 6. A sensor probe 8 and a slot 9 are installed on the bottom of the top wall of the door frame 1. A sensor contact point and a spring-loaded pivot 10 are installed on the top wall of the first door. The sensor probe 8 is configured to cooperate with the sensor contact point, and the slot 9 is configured to cooperate with the spring-loaded pivot 10. When the first door leaf 2 is pushed open, the spring-loaded pivot 10 retracts. When the first door leaf 2 is closed, the spring-loaded pivot 10 extends into the slot 9, and the first door leaf 2 is locked. The cooperation between the sensor contact point on the first door leaf 2 and the sensor probe 8 makes it automatically de-energized when the first door leaf 2 is opened and automatically closed when the first door leaf 2 is closed. The two sets of second door leaves 3 in the middle can slide freely in the track 4, and a pushing force can be applied to the second door leaf 3 to rotate and open it.
[0027] like Figures 1-3 As shown, the driving swing mechanism 7 includes a slide rail 11 and pulley seats 12. The slide rail 11 is horizontally fixed inside the top wall of the door frame 1. Two sets of pulley seats 12 are slidably connected to the slide rail 11 and are respectively connected to two sets of second door leaves 3. The driving swing mechanism 7 also includes a motor 13, belt tensioners 14 and a drive belt 15. The motor 13 is fixedly installed inside the top wall of the door frame 1. Two sets of belt tensioners 14 are rotatably installed inside the top wall of the door frame 1 and are oppositely arranged. The drive belt 15 is wound between the two sets of belt tensioners 14. A connecting block 17 is fixedly connected to one set of pulley seats 12. The connecting block 17 is connected to the drive belt 15. The upper half of the pulley seat 12 is connected to the other half of the pulley seat 12. The connecting block 18 is fixedly connected to the lower half of the drive belt 15. The output end of the motor 13 is connected to the rotating shaft of the belt tension wheel 14. The motor 13 drives the belt tension wheel 14 to rotate through the transmission belt 16. The drive belt 15 on the belt tension wheel 14 moves accordingly. The drive belt 15 drives the two sets of second door panels 3 to slide in opposite directions through the connecting block 17 and the connecting block 18, respectively. This ensures the coordination and consistency of the opening action of the two sets of second door panels 3, and ensures that the evacuation channel can be opened evenly and quickly, thereby improving evacuation efficiency.
[0028] like Figures 4-8As shown, a buckle 19 is provided on the second door leaf 3, and a fixed connector 20 is provided on the bottom of the top wall of the door frame 1. The fixed connector 20 and the buckle 19 are correspondingly matched and adapted. When a push force is applied to the second door leaf 3, the second door leaf 3 is opened by rotating the door leaf shaft 6. At this time, the buckle 19 is separated from the fixed connector 20. After the second door leaf 3 is rotated back to the initial state, the buckle 19 is engaged with the fixed connector 20, and the pulley seat 12 can drive the second door leaf 3 to slide in the groove 4 again.
[0029] In actual use, when a person needs to pass through, the motor 13 is powered on and runs. The motor 13 drives the belt tensioner 14 to rotate through the transmission belt 16. The belt tensioner 14 drives the drive belt 15 to move. The drive belt 15 drives the two sets of pulley seats 12 to slide in opposite directions on the slide rail 11 through the connecting block 17 and the connecting block 2 18. This causes the two sets of second door panels 3 to slide in the opposite direction along the groove rail 4 on the bottom wall of the door frame 1. The two sets of second door panels 3 slide towards the first door panels 2 on both sides and open.
[0030] Pushing the first door leaf 2 causes the elastic retaining shaft 10 to retract, and the first door leaf 2 opens by rotating through the door leaf shaft 5. After the sensing contact point on the first door leaf 2 separates from the sensing probe 8, the power is automatically cut off when the first door leaf 2 opens. Pushing the second door leaf 3 forcefully causes the second door leaf 3 to open by rotating through the door leaf shaft 6. At this time, the buckle 19 on the second door leaf 3 separates from the fixed connector 20 under the top wall of the door frame 1. At this time, both the first door leaf 2 and the second door leaf 3 are in the open state.
[0031] When the first door leaf 2 is closed, the elastic locking shaft 10 extends into the locking groove 9, locking the first door leaf 2. The cooperation between the sensing contact point on the first door leaf 2 and the sensing probe 8 causes the first door leaf 2 to automatically cut off power when it is rotated open and automatically close when it is closed. To close the second door leaf 3, rotate it back to its initial state, and the buckle 19 engages with the fixed connector 20. At this time, the second door leaf 3 can be driven to slide and close in the groove 4 again by the drive swing mechanism 7.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
