Description
Technical field
The present invention relates to technical field of elevator manufacturing more particularly to a kind of pool ladder locks, panel assembly and elevator calling box.
Background technique
Elevator calling box is mounted on the exterior wall of elevator floor stops, for the floor where calling elevator to reach passenger.Such as
Shown in Fig. 1, the outside of hall buttons would generally be provided with call button 11 ' and pool ladder lock 10 ', and call button 11 ' is commonly used in hair
Calling instruction out, mooring ladder lock 10 ' generally has operation and parked two states.When 10 ' switch of pool ladder lock gets to operating status, electricity
The terraced then calling instruction that can receive by pressing call button 11 ' and issue simultaneously is run according to instruction；When 10 ' switch of pool ladder lock is beaten
When to parked state, elevator then no longer receives the calling instruction issued by pressing call button 11 ', if getting to parked state
Had received before calling instruction, then complete it is registered call terraced task together after, rest in designated floor automatically, facilitate management
Personnel or engineering staff are into repairing elevator and safeguard.
In present building, in order to realize the conveying of more personnel, the transfer efficiency of elevator is improved, each floor is usually set
It is equipped with two parallel elevators.Usually setting interconnection elevator hall buttons realizes the control to two elevators, only needs to set on hall buttons
Instruction can be issued to two elevators by setting a set of call button 11 ', but need to be arranged two sets of pool ladder locks 10 ', each pool ladder
Lock 10 ' controls an elevator respectively.But two sets of pool ladder locks 10 ' of setting make inside sky complicated for operation, and occupying hall buttons
Between it is larger, cause hall buttons overall structure larger, occupy biggish installation space, increase dismounting cost and manufacture at
This.
Summary of the invention
It is an object of the invention to propose a kind of pool ladder lock, for realizing the control for two elevators.
