One kind rotates door stress way to play for time, by using above-mentioned rotation door stress buffer unit, is closed the door to rotating door
When the strong external force that is subject to enter row buffering.
Beneficial effect:
The present invention produces electric energy countershaft based on electromagnetic induction and produces resistance, so as to closing the door energetically into row buffering.This hair
Bright can effectively solve energetically the generation that door hits to wall at closing time, and low force is closed the door do not increase obstruction, be effectively increased by force by
While mechanical resistance Buddhist nun, the weak stress shutdown to old man and child etc. does not impact.
