Description

Technical Field

[0001] The utility model relates to the technical field of platform doors, in particular to a safe platform door connection structure. Background Art

[0002] As we all know, traditional platform doors often use mechanical locks to achieve connection and fixation between door bodies. This design is simple and direct. The mechanical locks are easily affected by external forces and fail. They cannot provide reliable anti-pry and anti-misopening protection, threatening passenger safety and track operation safety. Frequent opening and closing operations cause rapid wear of mechanical parts and increased maintenance costs. In an emergency, they may not be able to be unlocked quickly, affecting evacuation efficiency. With technological advances, some platform doors have begun to use basic electronic control devices such as electromagnetic locks to replace or assist mechanical locks. Although this is an improvement, it still faces challenges. Such systems often do not integrate effective buffer mechanisms, which will generate a large impact force when the door body is closed. In the long run, it will cause damage to the door body and noise pollution, affecting passenger experience and door life. Although the electromagnetic device has improved the level of automation, insufficient consideration is given to the maintenance and replacement of the electromagnetic lock. Once a failure occurs, a lot of disassembly work is required, affecting operational efficiency. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

In this embodiment, the left door 2 and the right door 3 are externally connected to the door switch drive device, and then the left door 2 can be conveniently opened and closed through the guide rail 1. The left door 2 and the right door 3 are connected or separated, so that it is easy to use. When the left door 2 and the right door 3 are in contact, the buffer mechanism can effectively buffer the impact force between the left door 2 and the right door 3 before they come into contact, thereby reducing the collision between the left door 2 and the right door 3. At this time, the locking iron block 6 of the left door 2 is against the electromagnetic lock 8 in the locking groove 5 of the right door 3, and then the electromagnetic lock 8 is opened. The electromagnetic lock 8 absorbs the locking iron block 6, which can fasten the left door 2 and the right door 3 together, ensuring the sealing reliability between the left door 2 and the right door 3, thereby improving safety and preventing people from accidentally opening the left door 2 or Right door 3, when separating left door 2 and right door 3, close electromagnetic lock 8, and then use external door switch equipment to separate left door 2 and right door 3 for easy use.

[0028] In the present embodiment, the guide mechanism includes a guide groove 16 and a guide block 17. The guide groove 16 is opened on one side of the buffer groove. The guide block 17 is slidably connected to the guide groove 16. The guide block 17 is connected to the buffer plate 14. The guide groove 16 opened on one side of the buffer groove is slidably connected to the guide block 17, so that the buffer plate 14 can drive the guide block 17 to move, and the guide block 17 moves linearly in the guide groove 16, so that the buffer plate 14 can move linearly more stably.

[0029] In this solution, two guide mechanisms are provided and are symmetrically arranged. By providing two guide mechanisms that are symmetrically arranged, the buffer plate 14 can move linearly more stably.

[0030] In this solution, the guide groove 16 and the guide block 17 are both in a T-shaped structure. The guide block 17 and the guide groove 16 in the T-shaped structure can make the guide block 17 move linearly in the guide groove 16 more stably.

[0031] In this solution, the buffer mechanism is provided in plurality, and by providing the plurality of buffer mechanisms, the impact force generated when the left door 2 and the right door 3 come into contact can be better buffered.

[0032] In this solution, the first elastic component 9 and the second elastic component 15 are both alloy springs. The alloy springs have the characteristic of good elastic support, so they can better play the elastic support effect.
