Problems solved by technology
If the ground is uneven, when the door leaf is opened at 90 degrees, the deadbolt near the ground may scratch the ground; if the height of the locking base of the deadbolt near the lintel is not standard, the locking depth will be difficult to adjust
[0004] 2. A trigger device for the lock tongue must be installed, and once the matching parts of the trigger device do not meet the installation requirements or become loose, the entire unlocking device will fail, and the reliability cannot be guaranteed

The invention discloses a transverse locking mechanism of a metro emergency door. The transverse locking mechanism of the metro emergency door comprises a total support, a locking rod which is straddled on the total support and capable of moving vertically, an upper cylinder part, a lower cylinder part, an upper locking seat part which is locked with the upper cylinder part and a lower locking seat part which is locked with the lower cylinder part; a first transferring shifting piece is arranged between the locking rod and the upper cylinder part; and the upper cylinder part comprises an upper bolt sleeve and an upper bolt. When the locking rod pushes the first transferring shifting piece, the other end of the transferring shifting piece drives the upper bolt to transversely unlock. A second transferring shifting piece is arranged between the locking rod and the lower cylinder part, and the lower cylinder part comprises a lower bolt sleeve and a lower bolt. When the locking rod pulls the second transferring shifting piece in a mobile mode, the other end of the second transferring shifting piece drives the lower bolt to transversely unlock. The transverse locking mechanism of the metro emergency door has the advantages of achieving transverse locking between one side of the emergency door and a doorframe, avoiding mutual abrasion between the bolt and the earth, simultaneously simplifying the locking process and the unlocking process, enabling the installation of the door lock to be convenient and guaranteeing the reliability of locking and unlocking.
Description
technical field [0001] The invention relates to a door lock mechanism, in particular to a transverse lock mechanism used on an emergency door in a screen door system in a subway station. Background technique [0002] With the continuous development of the national economy, public transportation, especially subway construction, has been extensively developed, and many large cities are developing subway construction. However, in order to ensure the safety of passengers, a screen door system is installed on the edge of the platform to isolate the station platform from the driving tunnel area, so as to reduce the energy consumption of the station’s air conditioning and ventilation system, reduce the impact of train running noise and piston wind on the station, and provide passengers with Safe and comfortable waiting environment. At the same time, it also prevents passengers on the platform from falling into the track due to carelessness or crowding, causing harm to passengers a...
