Retractable safety door
The invention provides a retractable safety door. The retractable safety door comprises a door frame and a door leaf hinged to the door frame, wherein the door leaf sequentially comprises an outer door plate, an inner core and an inner door plate in the thickness direction; the inner core comprises side edges hinged to the door frame and a retractable door core, and when in a normal use state, theretractable door core is unfolded to be propped against and matched with three surfaces, except a hinged surface, of an inner ring of the door frame; and in a contraction state, the retractable doorcore does not make contact with the inner ring of the door frame. The retractable safety door has the advantages that during normal use, the retractable door core is unfolded to be matched with the other three surfaces, except the hinged face, of the inner ring of the door frame, so that isolation of an inner space and an outer space is achieved, and smoke is prevented from permeating; and in thecontraction state, the retractable door core does not make contact with the inner ring of the door frame, so that the door leaf is normally opened under the condition that the door frame 1 deforms, and accordingly safety is improved.
本发明提供了一种伸缩式安全门，包括门框和铰接在门框上的门扇，所述门扇沿厚度方向依次包括外门板、内芯和内门板，所述内芯包括与门框铰接的侧楞以及伸缩门芯，正常使用状态时，所述伸缩门芯展开与门框内圈除铰接面之外的三个面抵接吻合；收缩状态时，伸缩门芯与门框内圈均无接触。本发明提供的伸缩式安全门的优点在于：在正常使用时伸缩门芯展开与门框内圈除铰接面之外的其他三个面配合，实现内外空间的隔离，防止烟雾渗入，收缩状态时，伸缩门芯与门框内圈均无接触，可以在门框1发生变形的情况下确保门扇能够正常打开，提高安全性。
