Description

Technical Field

[0001] The utility model relates to the field of subway safety doors, in particular to a subway safety door synchronization mechanism. Background Art

[0002] With the development of urban transportation, the use of subways is becoming more and more popular. Since subway platforms are crowded, safety is the primary consideration among many technical indicators. When the train has not arrived at the platform or started, the subway platform safety doors need to be closed to prevent accidents. The synchronous opening or closing of subway safety doors can increase the speed of opening or closing of subway safety doors and enable the subway safety doors to operate smoothly. Therefore, a synchronous structure is needed to enable the subway safety doors to be opened or closed synchronously.

[0003] An existing subway safety door synchronization mechanism includes a motor and a rotating rod, wherein two ends of the rotating rod surface are respectively provided with threads in opposite directions, and the rotating rod surface is provided with two moving blocks, which are respectively threadedly connected to the two ends of the rotating rod surface, and one side of the two moving blocks is respectively fixedly connected to one side of the two safety doors. The rotating rod is driven by the motor to rotate, so that the rotating rod drives the two moving blocks to be relatively close or relatively far away, thereby making the two moving blocks drive the two safety doors to be relatively close or relatively far away, respectively. Through the above structure, the subway safety doors can move synchronously, but since the subway safety doors require high installation accuracy, after installation, it is necessary to ensure that the distances from the two moving blocks to the center of the rotating rod are the same to ensure that the two safety doors are symmetrically opened or closed. Since the rotation of the rotating rod will drive the two moving blocks to move at the same time, it is inconvenient to adjust the accuracy of the subway safety doors.

[0004] Therefore, it is necessary to provide a new subway safety door synchronization mechanism to solve the above-mentioned technical problems. Utility Model Content
