STOPPER FOR ELECTROMAGNETIC WAVE SHIELDING DOOR

摘要

PURPOSE: A stopper for an electromagnetic wave shield door is provided to restrict the opening degree of a shield door when the shield door is opened and to safely fix the opened state of the shield door. CONSTITUTION: A stopper for an electromagnetic wave shield door comprises a housing(10), a damper rod, a magnet(30), and a guide unit(40). The housing is fixed to the outside floor(F) of an electromagnetic wave shield room to be located within the rotation radius of a shield door(D). The damper rod is composed of a first rubber rod and a second metal rod(22). The first rubber rod supports the outer surface of the shield door. The second metal rod is fixed to the rear end of the first rubber rod. The magnet is formed on the front end of the damper rod and fixes the opened state of the shield door. The guide unit guides the movement of the damper rod.
