The invention relates to the technical field of escape systems, in particular to a universal type escape system for a subway locomotive. The universal type escape system for the subway locomotive is applied to the condition that passengers safely escape to the subway track surface from the interior of a train through operation of a driver or the passengers when the subway train is in an emergency state. The universal type escape system for the subway locomotive mainly comprises a seal frame, a door page, a connecting rod mechanism and a lock mechanism; the seal frame and the connecting rod mechanism are both fixed on a locomotive body; the connecting rod mechanism is located at the back end of the door page; the lock mechanism is integrally installed on the upper portion of the inner side of the seal frame; under the action of the connecting rod mechanism, the door page simultaneously does composite type motion of horizontal moving and turning in the opening process; the door page automatically turns to be opened after being pushed by operation personnel; when the door page is folded into the seal frame, the lock mechanism automatically locks the door page. According to the escape system, the weight is smaller, the occupied space is smaller, the opening action of the door page is simple, horizontal moving and turning of the door page are completely achieved through one action, the folding speed is higher, a large amount of folding time is saved, the structure is simple, the reliability is high, the passing width is large, and meanwhile it can be guaranteed that the escape system is suitable for various locomotive types.

The invention discloses an auxiliary mechanical linkage lock. The auxiliary mechanical linkage lock comprises a lock case, an upper pull rod, a lower pull rod, a pull rod driving mechanism and a pull rod fixing mechanism. The upper pull rod is connected with an upper bolt, the lower pull rod is connected with a lower bolt, the upper pull rod and the lower pull rod are connected through a gear and rack transmission assembly, and a cavity used for containing a latch of a main lock is formed between the upper pull rod and the lower pull rod. The pull rod driving mechanism is used for driving the upper pull rod and the lower pull rod to be simultaneously opened or closed in the longitudinal direction, and the pull rod fixing mechanism is used for fixing the opened upper pull rod and the opened lower pull rod. The pull rod driving mechanism comprises a driving wheel driven block, a driving wheel piece, a driving wheel and a first driving gear, wherein the driving wheel driven block, the driving wheel piece, the driving wheel and the first driving gear are coaxially arranged. The pull rod fixing mechanism comprises a fixing bolt, a second driving gear, a first cushion block, a bolt connecting piece, a first metal plate, a second metal plate and a bolt rack, wherein the first metal plate, the second metal plate and the bolt rack are fixed to the bottom surface of the bolt connecting piece. The auxiliary mechanical linkage lock is good in safety and anti-theft performance, has an automatic locking function and can improve the safety and anti-theft performance of an interior door when used in cooperation with the main lock installed on the interior door.
