DETAILED DESCRIPTION​​​

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, an emergency manual escape device for rail transit platform doors includes an installation compartment 1. A first bracket 2 is placed at the bottom inner side of the installation compartment 1. A sliding groove 4 is opened at one end of the first bracket 2. A connecting sleeve 5 is movably connected to the inner side of the sliding groove 4. A rotating plate 6 is fixedly connected to the upper end of the connecting sleeve 5. A connecting rod 8 is movably connected to the inner side of the rotating plate 6 through a rotating shaft. A lock head 7 is installed at the upper end of the rotating plate 6. A top rod 9 is slidably connected to the inner side of the sliding groove 4. A connecting ring 11 is fixedly connected to the outer side of the top rod 9 near the sliding groove 4. A spring 12 is sleeved on the outer side of the top rod 9 near the connecting ring 11. A second bracket 13 is slidably connected to the outer side of the top rod 9 near the spring 12. An adjusting block 15 is fixedly connected to one end of the top rod 9.

[0021] In this embodiment, both the first bracket 2 and the second bracket 13 are L-shaped. The lock head 7 penetrates the interior of the installation chamber 1 and is fixedly connected to the installation chamber 1. The outer side of the connecting rod 8, near the rotating plate 6, is movably connected to the inner side of the top rod 9 through a rotating shaft. One end of the spring 12 is fixedly connected to one end of the connecting ring 11, and the other end of the spring 12 is fixedly connected to one end of the second bracket 13.

[0022] Specifically, in the event of an emergency, the flight attendant takes out the key, inserts it into the lock cylinder 7, and turns the key to open the lock cylinder 7, thus preventing the lock cylinder 7 from contacting the rotating plate 6. Then, the connecting sleeve 5 is pulled to rotate, causing the connecting sleeve 5 to push the connecting rod 8 through the rotating plate 6. This causes the connecting rod 8 to push the push rod 9 to move within the sliding groove 4, and the push rod 9 to compress the spring 12 through the connecting ring 11. Simultaneously, the push rod 9 causes the adjusting block 15 to contact the vehicle's electromagnetic lock, thereby opening the vehicle's electromagnetic lock. This allows the platform screen door to be opened manually, facilitating passenger escape. By rotating the connecting sleeve 5, the connecting sleeve 5 pushes the connecting rod 8 through the rotating plate 6, and the connecting rod 8 moves the push rod 9. This causes the push rod 9 to compress the spring 12 through the connecting ring 11, and the push rod 9 to move the adjusting block 15. This facilitates the adjusting block 15 contacting the vehicle's electromagnetic lock, and after contacting the vehicle's electromagnetic lock, the platform screen door can be manually pushed open, facilitating passenger escape.

[0023] In this embodiment, the lower end of the second support 13 is in contact with the inner bottom of the mounting bin 1 near the side of the first support 2, the second support 13 is internally threaded with the second bolt 14, the first support 2 is internally threaded with the first bolt 3, the first bolt 3 extends to the inside of the mounting bin 1, the first bolt 3 is threaded between the mounting bin 1, the second bolt 14 extends to the inside of the mounting bin 1, the second bolt 14 is threaded between the mounting bin 1, the connecting sleeve 5 penetrates the inside of the mounting bin 1, the connecting sleeve 5 is movably connected with the mounting bin 1, and the lower end of the connecting sleeve 5 is fixedly connected with the door handle 10.

[0024] Specifically, loosen the door handle 10, and make the spring 12 rebound outward, so that the spring 12 pushes the top rod 9 to move reversely through the connecting ring 11, and the top rod 9 drives the adjusting block 15 to reset, so that the rotating plate 6 resets, and then the attendant locks the lock head 7 with the key, so that the lock head 7 limits the rotation of the rotating plate 6, thereby avoiding the passenger accidentally pushing the door handle 10 to rotate.

[0025] Working principle:

[0026] In use, first install the mounting bin 1 in the door frame, and make the adjusting block 15 touch the electromagnetic lock of the vehicle, if an emergency occurs, the attendant takes out the key, inserts the key into the lock head 7, and turns the key to open the lock head 7, so that the lock head 7 is not in contact with the rotating plate 6, then pull the door handle 10 to make the door handle 10 drive the connecting sleeve 5 to rotate, and then make the connecting sleeve 5 push the connecting rod 8 to move through the rotating plate 6, so that the connecting rod 8 pushes the top rod 9 to move in the sliding groove 4, and at the same time, the top rod 9 compresses the spring 12 through the connecting ring 11, and the top rod 9 drives the adjusting block 15 to contact the electromagnetic lock of the vehicle, so that the adjusting block 15 opens the electromagnetic lock of the vehicle, thereby manually opening the shielding door and facilitating the escape of the passenger, then loosen the door handle 10, and make the spring 12 rebound outward, so that the spring 12 pushes the top rod 9 to move reversely through the connecting ring 11, and the top rod 9 drives the adjusting block 15 to reset, so that the rotating plate 6 resets, and then the attendant locks the lock head 7 with the key, so that the lock head 7 limits the rotation of the rotating plate 6, thereby avoiding the passenger accidentally pushing the door handle 10 to rotate, by rotating the connecting sleeve 5, the connecting sleeve 5 pushes the connecting rod 8 to move through the rotating plate 6, and the connecting rod 8 drives the top rod 9 to move, so that the top rod 9 compresses the spring 12 through the connecting ring 11, and the top rod 9 drives the adjusting block 15 to move, which can achieve the purpose of facilitating the adjusting block 15 to touch the electromagnetic lock of the vehicle, and after the adjusting block 15 touches the electromagnetic lock of the vehicle, the shielding door can be manually pushed open, thereby facilitating the escape of the passenger.
