Abstract

Et lukkehodeapparat for en utblåsningssikring, hvor nevnte lukkehodeapparat omfatter et stempel (50) for å kunne bevege en lukkehodeblokk, samt en låseaksel (40) som strekker seg fra stempelet (120, 50) og inn i et hus (22), karakterisert ved at nevnte låseaksel (40) omfatter et konisk parti (41); at lukkehodeapparatet videre omfatter et låseelement (70); og at nevnte låseaksel (40) sitt koniske parti (41) er slik innrettet at det kan bevege seg frem til nevnte låseelement (70) når nevnte stempel (120, 50) strekkes ut under bruk, hvorpå nevnte låseelement (70) beveger seg mot nevnte koniske parti (41) for å hindre tilbaketrekking av nevnte stempel (120, 50).
