Rail transit double-opening sliding plug door

Abstract

The invention relates to a rail transit double-opening sliding plug door. The door comprises a door leaf and a door frame; the door leaf is installed on the door frame; a locking groove is formed in the door frame; a locking cavity is formed in the door leaf; a sliding hole and a locking hole are formed in the locking cavity; a high-speed locking device is installed in the locking cavity; the high-speed locking device comprises a piston, a linkage mechanism, a reset spring and a locking rod, the piston is installed in the sliding hole and connected with the locking rod through the linkage mechanism, the locking rod is installed in the locking cavity in a sliding mode, one end of the locking rod is installed in the locking hole and can penetrate out of the locking hole to enter the locking groove, the piston drives the locking rod to slide through the linkage mechanism, and the two ends of the reset spring are fixedly connected with the side wall of the locking cavity and the locking rod respectively. With the rail transit double-opening sliding plug door adopted, the defect that a sliding plug door is automatically opened in the high-speed running process of a vehicle is overcome.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a rail transit double-opening sliding door. Background technique [0002] At present, the sliding door means that the door has a sliding action during the whole opening and closing process, and the outside of the door is flat with the outer skin of the vehicle body when the door is closed, and overlaps with the vehicle body when the door is opened. The double-opening sliding door system is mostly used in rail vehicles. During the high-speed running of the vehicle, due to the air pressure difference between the inside and outside of the sliding door, especially when the relatively high-speed vehicles meet, the sliding door is subject to a large outward pulling force. , causing the sliding door to open automatically, posing a huge threat to the personal safety of the occupants. [0003] With regard to the related technologies mentioned above, the inventor believes that there is a defec...

AI Technical Summary

Problems solved by technology

The double-opening sliding door system is mostly used in rail vehicles. During the high-speed operation of the vehicle, due to the air pressure difference between the inside and outside of the sliding door, especially when the relatively high-speed vehicles meet, the sliding door is subject to a large outward pulling force. , causing the sliding door to open automatically, posing a huge threat to the personal safety of the occupants

[0003] In view of the related technologies mentioned above, the inventor believes that there is a defect that the sliding door is automatically opened due to the outward pulling force when the vehicle is running at high speed.
