| description | The utility model relates to a metal safety door of a fast passage, which comprises a door frame and a metal door surface, and the door frame is hinged and fixed with a first end of the door surface through a hinge; buffer parts are arranged at the top end, the bottom end and the second end opposite to the first end of the door surface; the length of the buffer part is equal to the side length ofthe door surface; the buffer part is elastically connected with the door surface through at least two parallel springs; at least two guide rods are arranged at the bottom of the buffer part, and guideholes matched with the guide rods are formed in the door surface; the upper part of the cross section of the buffer part is trapezoidal; and when the door is closed, the upper bottom of the trapezoidis contacted with the inner side surface of the door frame. One technical problem to be solved by the utility model is that a door is easily stuck under the influence of an external environment. Thesafety door is firm, durable |
