Description

Technical Field

[0001] This utility model relates to the field of emergency switch technology, and in particular to a novel subway emergency switch. Background Technology

[0002] Subway emergency switches are designed to maximize passenger safety and provide necessary assistance in critical moments, making them an indispensable part of the subway safety system. Emergency switches allow passengers or staff to take immediate action in emergencies, activating emergency procedures without waiting for external instructions, thus quickly responding to potential dangers. By providing a direct method to stop trains or open doors, emergency switches can help reduce the risk of injury caused by sudden events. Most emergency switches are simple and intuitive to design, requiring only a simple action to activate without specialized technical knowledge or training. However, currently available subway emergency switches have common drawbacks: firstly, some emergency switches lack anti-accidental activation design, easily triggering the system's emergency braking due to passenger misoperation; therefore, designing a new type of subway emergency switch is essential. Utility Model Content

[0003] The purpose of this invention is to provide a new type of subway emergency switch to solve the problem that some existing emergency switches lack anti-accidental contact design and are prone to triggering the system's emergency braking due to passenger misoperation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel subway emergency switch, comprising a supporting shell, an electromagnet, a limit block, a locking block, and a limit switch. A second rotating shaft is rotatably connected to the supporting shell. A pull plate, a first cam, and a second cam are fixedly connected to the second rotating shaft. The pull plate is in close contact with the first cam and the second cam. A first rotating shaft is rotatably connected to the supporting shell. A door panel is fixedly connected to the first rotating shaft. A cover plate is fitted into a groove on the door panel. A first protective plate is fixedly connected to the door panel by bolts. The first protective plate is in close contact with the cover plate.

[0005] As a further technical solution of this utility model, a lock hook is fixedly connected to the door panel.

[0006] As a further technical solution of this utility model, a limit switch is fixedly connected to the bottom of the support housing by bolts, a third rotating shaft is rotatably connected to the bottom of the support housing, and a locking block is fixedly connected to the third rotating shaft, the locking block being sleeved in the groove of the first cam.

[0007] As a further technical solution of this utility model, an electromagnet is fixedly connected to the bottom of the supporting shell, and a second protective plate is fixedly connected to the bottom of the electromagnet by bolts.

[0008] As a further technical solution of this utility model, one end of a limiting block is sleeved in the groove of the first cam, and the other end of the limiting block is sleeved in the through groove of the second cam.

[0009] As a further technical solution of this utility model, a locking shaft is rotatably connected in the through hole of the supporting shell.

[0010] As a further technical solution of this utility model, a first elastic cylindrical pin and a second elastic cylindrical pin are fixedly connected in the through hole opened on the locking shaft, and the first elastic cylindrical pin passes through the through groove opened in the supporting shell.

[0011] This utility model provides a novel subway emergency switch with the following advantages: When the emergency unlocking mechanism is triggered, the electromagnet is de-energized and unlocked. The second elastic cylindrical pin rotates clockwise, which in turn drives the lock shaft to rotate clockwise, ultimately driving the first elastic cylindrical pin to rotate clockwise. The first elastic cylindrical pin is then rotated out of the lock hook. Through the through hole in the first protective plate, the cover plate, the first protective plate, and the door plate are pulled to rotate around the first rotating shaft, ultimately opening the door plate. Pulling the pull plate upwards drives the second rotating shaft to rotate, which in turn drives the first cam and the second cam to rotate. The first cam drives the lock block to rotate around the third rotating shaft. The limit switch can prevent the second cam from exceeding the predetermined operating range, thereby avoiding damage to the equipment. The emergency switch has multiple anti-accidental touch designs, preventing the system's emergency braking from being triggered by passenger misoperation, ensuring the safety of the emergency switch and eliminating safety hazards.

[0018] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a novel subway emergency switch, comprising a supporting housing 1, an electromagnet 11, a limiting block 12, a locking block 13, and a limiting switch 16. A second rotating shaft 4 is rotatably connected to the supporting housing 1. A pull plate 3, a first cam 9, and a second cam 15 are fixedly connected to the second rotating shaft 4, with the pull plate 3 closely abutting against the first cam 9 and the second cam 15. A first rotating shaft 2 is rotatably connected to the supporting housing 1, with a door panel 8 fixedly connected to the first rotating shaft 2. A cover plate 5 is fitted into a groove in the door panel 8. A first protective plate 6 is fixedly connected to the door panel 8 by bolts, with the first protective plate 6 closely abutting against the cover plate 5. A locking hook 7 is fixedly connected to the door panel 8. A limiting switch 16 is fixedly connected to the bottom of the supporting housing 1 by bolts. A third rotating shaft 14 is rotatably connected to the bottom of the supporting housing 1, with a locking block 13 fixedly connected to the third rotating shaft 14. The limit switch 16, fitted into the groove of the first cam 9, prevents the second cam 15 from exceeding the predetermined operating range. An electromagnet 11 is fixedly connected to the bottom of the support housing 1, and a second protective plate 10 is fixedly connected to the bottom of the electromagnet 11 by bolts. One end of the limit block 12 is fitted into the groove of the first cam 9, and the other end of the limit block 12 is fitted into the through groove of the second cam 15. The limit block 12 is used to synchronize the rotation of the first cam 9 and the second cam 15. A locking shaft 17 is rotatably connected into the through hole of the support housing 1.
