Preferably, the drive division is a part of side of rotating lever, the side is mutually made with unlocking the end of swing rod With.In order to reduce friction, extend driving lever and unlock the service life of swing rod, it is preferable that the end for unlocking swing rod is provided with and drive The anti-attrition roller that dynamic portion is engaged.The side of the rotating lever is provided with the guide chute being engaged with anti-attrition roller.
Preferably, the drive division is the termination of rotating lever, the termination is mutually made with unlocking a part of side of swing rod With.In order to reduce friction, extend driving lever and unlock the service life of swing rod, it is preferable that the termination of the rotating lever is provided with The anti-attrition roller being engaged with unblock swing rod.The side of the unblock swing rod is provided with the guide chute being engaged with anti-attrition roller.
Preferably, being additionally provided with the mechanical lock on layer door, mechanical lock has rotatable lock core, solid on the lock core Surely there is drawing piece, the one end of the unlock rope away from rotating lever is connected on the drawing piece.The mechanical lock can use three Lock at angle.
Preferably, drawing piece is tabular or shaft-like.
The utility model compared with prior art, has advantages below:
(1) tripper is not contacted directly with layer door lock, and tripper will not be touched after layer door-lock opening, avoids solving Lock rope catches on miscellaneous part after unclamping, and good reliability is safe;
(2) simple in construction, small volume, manufacturing cost is low, suitable for the elevator of different enabling height, the position of end of door plate lockhole Put and require low, it is versatile;
(3) when needing to realize pit unblock, it is only necessary to by unlock rope extended length to being connected to door-plate correct position, you can It is largely cost-effective without redesigning new pit tripper with by pulling unlock rope to be unlocked.
