The invention discloses a fast-open door structure for a flame-proof casing, relates to the fast-open door structure for the flame-proof casing and mainly aims at solving the problems that the flame-proof casing is troublesome and strenuous when opened and closed by using a bolt fastening structure and an existing fast-open door structure is poor in fastening strength. The fast-open door structure disclosed by the invention comprises a flame-proof box, a flame-proof box cover plate and hinge mechanisms, wherein the fast-open door structure is characterized in that two ends of a shifting shaft of each hinge mechanism are inserted into piston cylinders; the piston cylinders are fixed on corresponding fixators of which the sections are U-shaped; the hinge mechanisms are fixed on the flame-proof box cover plate through corresponding hinge bases; and the hinge mechanisms are snapped on the edges of the flame-proof box through the corresponding fixators of which the sections are U-shaped. According to the fast-open
