[0003] However, the existing hand-pull door lock unlocking method is that the door knife pushes the connecting rod of the swing ball to unlock (the paddle to unlock) or the pull cord to pull the unlocked linkage to unlock (the pull cord to unlock), when the paddle is unlocked, The door knife must be close to the position of the door lock, so that the door knife can push the gate ball, and then drive the paddle to unlock, so that its use is limited. When the pull rope is unlocked, the pull rope is connected to the paddle, and the pull rope first pulls the paddle to rotate In order to drive the lock cylinder to unlock, the stroke of the pull rope is longer, so that the pull rope is easy to wear and tear during long-term use
And the existing hand-pull door lock unlocking method can only be any one of them, so that it cannot be flexibly selected according to the environment on site, and the use is limited

[0043] First, select the appropriate unlocking method according to the distance between the door lock and the door knife, that is, the pull cord unlocking and the paddle unlocking, specifically, one end of the pull rope 4 is connected to the door ball, or the paddle 5 is connected to the connecting rod , so that the pull cord 4 and the pick piece 5 can drive the lock tongue 2 to extend or retract the housing 1 through the lock cylinder 3 . Specifically: the stay cord 4 pulls the lock core 3, and due to the setting of the guide 41, the angle of the stay cord 4 can be set as required, and the lock core 3 can drive the lock tongue 2 When the housing 1 is retracted, the first reset member 12 is compressed, and when the lock tongue 2 needs to protrude from the housing 1, the first spring 12 can reset the lock tongue 2 . The rotating plectrum 5 can move the lock cylinder 3 through the cylindrical block and the groove, so that the lock tongue 2 is retracted into the housing 1, and t...

The invention discloses an elevator hand pulling door lock. The elevator hand pulling door lock comprises a shell, a lock tongue, a pull rope and a poking piece, wherein the lock tongue is arranged onthe shell and slidingly contacted with the shell; the lock tongue is fixedly connected with a lock cylinder capable of driving the lock tongue to extend out or shrink back from the shell; one end ofthe pull rope is fixedly connected with the lock cylinder; and one end of the poking piece is fixedly connected with the lock cylinder. The pull rope is fixedly connected with the lock cylinder, so that the pull rope can directly pull the lock cylinder, and is shorter in travel and difficult to wear; two unlocking modes of poking piece unlocking and pull rope unlocking are provided, and can be flexibly selected according to scene environments to achieve convenience to use; and through cooperation of a limiting groove, a connecting piece, an ejector rod, a boss and a mechanical switch, a control loop can be formed to prevent the condition of not closing an elevator door in the elevator operating process.
Description
technical field [0001] The invention relates to the technical field of elevator door locks, in particular to an elevator pull-door door lock. Background technique [0002] Elevator car doors are divided into automatic and manual (hand-pull doors). Automatic doors take up a lot of space, while hand-pull doors take up less space, making them widely used in small scenes such as villas. Door locks should be set on the pull doors to ensure the safety of passengers. [0003] However, the existing hand-pull door lock unlocking method is that the door knife pushes the connecting rod of the swing ball to unlock (the paddle to unlock) or the pull cord to pull the unlocked linkage to unlock (the pull cord to unlock), when the paddle is unlocked, The door knife must be close to the position of the door lock, so that the door knife can push the gate ball, and then drive the paddle to unlock, so that its use is limited. When the pull rope is unlocked, the pull rope is connected to the pa...
