Abstract

The invention discloses an elevator car door lock device and an elevator. The elevator car door lock device comprises a lock hook mechanism, a lock bracket mechanism, a striking rod and an unlocking baffle, wherein the lock hook mechanism is used for being installed on a door machine plate and can rotate relative the door machine plate; the lock bracket mechanism and the striking rod are used for being installed on a door hanging plate, the lock bracket mechanism and the lock hook mechanism are matched in an interlocking mode, when a car door is closed, the striking rod is attached to the lock hook mechanism and abuts against the lock hook mechanism, the unlocking baffle is used for being installed on a door head plate, the unlocking baffle and the striking rod are used for being matched with the lock hook mechanism, and therefore the lock hook mechanism is in an unlocking state or a locking state. According to the elevator car door lock device and the elevator, unlocking or locking operation is independent of other door machine action systems and is suitable for developing a new door opening machine and additionally arranging a car door lock on an old door opening machine, and the elevator car door lock device is high in generality and long in service life.

Description

technical field [0001] The invention relates to the field of elevator door systems, in particular to an elevator car door lock device and an elevator. Background technique [0002] As a daily means of transportation, elevators are used every day in life. Due to their particularity, it is required to prevent accidents as much as possible. In the past accident cases, accidents caused by elevators opening doors in non-opening areas accounted for a certain proportion, which had a serious impact on elevator safety. Traditionally, in order to prevent accidents caused by the elevator car opening the door in a non-opening area, it is generally protected by installing a door lock on the door operator. However, there are many types of door operators in the elevator market, and most door locks only add door lock protection to newly developed door operators, and generally need to cooperate with other door operator action systems. The structure is complex, and it is difficult to install...
