Description
Technical field
The utility model is related to elevator technology fields, more particularly to a kind of elevator, fire door system and tripper.
Background technology
It is mostly that driving lever is unlocked in the tripper of traditional vertical lift layer door board lock.When constant, the layer of lockhole height
When door board height increases, layer door board lock, which is opened, just will produce locking bar long arc；And locking bar cantilever increases, rigidity declines, no
It is run conducive to elevator.
Traditional driving lever is unlocked, as being applied on fire door system：It, need to be heat-insulated because heat-barrier material tegillum door board wraps up
Open gap on material influences the thermal insulation of fire door system.
Invention content
Based on this, it is necessary to provide a kind of elevator, fire door system and tripper.The latch hook closure of the tripper can
It leans on, can ensure applied on Super High door board in elevator operation, latch hook is unlikely to when door board is hit layer by layer
