[0032] A lower roller 5 is provided at the bottom end of the subway door 3; and a lower groove seat 6 is arranged at the bottom end of the lower roller 5. Specifically, firstly, a transmission belt 203 is sleeved between the output end of the rotating motor 201 and the middle part of the rotating shaft 202. By turning on the rotating motor 201, the rotating shaft 202 is driven to rotate. The rotation of the rotating shaft 202 will drive the screw 204 connected to the front end of the rotating shaft 202 to rotate. Since the transmission block 205 is tightly combined with the screw 204, the transmission block 205 will move left and right along the screw thread of the screw 204, and the upper roller 206 at the bottom end of the transmission block 205 can be moved left and right with the subway door 3.

During the movement of the lubricating oil bottle 404,The vibration generated can make the oil in the lubricating oil bottle 404 drop onto the transmission block 205 and the screw 204, so as to lubricate the friction between the transmission block 205 and the screw 204, thereby avoiding jamming and friction damage between the transmission block 205 and the screw 204. The user can observe the amount of oil in the lubricating oil bottle 404 by observing the observation cover 405 at the outer end of the slide 401, so as to facilitate better lubrication.

The advantage of this technical solution is that the lower roller 5 is provided at the bottom end of the subway door 3, and the movement of the subway door 3 will drive the lower roller 5 in the lower groove seat 6. By moving the door 3, the subway door 3 can be opened and closed more stably. A fixing plate 701 is welded between the guide rail frame 1 and the rear end of the lower slot seat 6.
