Described driving device comprises the synchronous band connecting panel of tape guide groove, in the tape guide groove pressing plate is set, synchronously with the synchronous band that compresses between connecting panel and the pressing plate.
On the synchronous band connecting panel of described pressing plate upside induction magnetic head is set.
The upper plate of the described hinged connecting plate that hits plate and the hinged balance connecting plate of opposite side of lower plate.
On the described door machine boatswain chair manual unlocking device is installed, manual unlocking device is a shank of unblanking that can spur and be equipped with retracing spring up and down, described lock body be positioned at the shank crotch of unblanking below.
Also be provided with the glue hook bolt on the described lock.
Be provided with the glue beans in the groove of described group of frame.
The described lower plate downside that hits the connecting plate of plate is provided with the fixed limit block.
The door cutter is the external-expanding type structure in the structure of the present invention, stable performance, and open concordant, the good looking appearance in gate doorway, opisthodome for synchronous door knife makes elevator door, adopted a kind of a kind of version that makes held stationary behind the cutter spreading, the rubber buffering is all adopted at the position that is easy to send noise.This patent structure adopts the rolling plane contact, bearing arrangement is all adopted at each rotational parts position, makes that friction force reduces between each action component, makes each parts flexibly movable, and be mechanical structure form completely, make that elevator runs more secure, reliable, performance is more stable.
