[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the rotation of the rotating shaft drives the transverse bevel gear to rotate, and the rotation of the transverse bevel gear drives the two screw rods to rotate synchronously through the meshing with the two vertical bevel gears. The synchronous rotation of the two screw rods drives the two threaded blocks to move synchronously on their outer surfaces respectively, and move closer to or away from each other. The mutual approach or distance between the two threaded blocks drives the two connecting rods to move closer to or away from each other, so that the double doors are driven to slide left and right inside the sliding door frame through the connection between the two fixed plates and the double doors, thereby forming the opening and closing of the double doors. The structure is simple and easy to operate. It not only provides protection for the subway debugging power supply, but also facilitates the later maintenance work of the subway debugging power supply through the opening and closing of the double doors, provides convenience, and ensures the safety performance of the subway power supply.

[0016] 2. In the utility model, when the double-opening door is moving, the movable seat moves inside the movable groove, and under the elastic push of the reset spring, the movable seat is pushed up by the limit plate, so that the outer surface of the roller on the top of the movable seat contacts the upper and lower ends of the double-opening door. When the double-opening door is opened and closed, the roller rolls on the outer surface of the rotating shaft inside the rolling groove, providing power to the double-opening door to facilitate its opening and closing movement. This structure provides rolling force when the double-opening door is opened and closed, which is convenient for the opening and closing of the double-opening door, thereby facilitating the inspection and maintenance of the subway debugging power supply.
