Description
Technical field
This utility model is related to a kind of elevator synchronous door knife, the elevator synchronous door knife of particularly a kind of integrated car door lock.
Background technology
Commonly use that to have brought be greatly very convenient with elevator, meanwhile people when taking a lift, its peace
Full performance is also of increasing concern.Specify in China's GB：" elevator hoistways inner surface and car sill, car door frame or cunning
The horizontal range at the nearest doorway edge of dynamic door not should be greater than 0.15m.Wherein it further provides that：If car is equipped with mechanical interlocking
Door and can only open in the unlocking area of floor door, in addition to special circumstances, the operation of elevator automatically depends on the locking of gate, and
Gate locking must have electric safety device to confirm, then above-mentioned spacing is unrestricted ".
To above-mentioned regulation, the scheme that prior art is taken is：Add protecting wall in hoistway inner surface or independent sedan-chair is installed
Door lock, in order to avoid in Lift out of order, passenger does not know about correct escape method, opens gate escape, thus causing danger.
But protecting wall high cost is installed and so that elevator installation period is extended；Installing independent car door lock needs in every layer of setting unblock knife
Piece, is so accomplished by just installing car door lock when installing elevator, and will accurately adjust at the scene.Especially when floor relatively
High situation, car runs up and down and has deviation unavoidably, brings bigger difficulty to the installation of unblock blade, also makes gate simultaneously
The fault rate of lock is significantly increased.
