The invention discloses a shielding door structure. The shielding door structure is mainly characterized in that one end of a door hinge shaft is connected with a door frame body; the other end of the door hinge shaft is connected with a shielding door; when the shielding door is closed, the door hinge shaft serves as a
hinge point, a door reed on the outline face of the shielding door is compressed on the door frame body, and the shielding door is connected with the door frame body in an attached mode; the door frame body comprises door frame strips and a doorsill
whole body; the door frame strips are arranged on left, right and upper door frames of the door frame body and are provided with inclined planes; the doorsill
whole body is arranged on the ground and is provided with inclined planes; and the left and right ends of the doorsill
whole body are connected with the left and right door frame strips respectively. Conductive continuity of the shielding door is achieved, and the situation that, for an
electromagnetic field generated by special equipment in a blocking and
refraction space in a shielding room, the
electromagnetic field in the shielding room is not exposed to the outside is guaranteed; and electric signals outside the shielding room are isolated, so that electromagnetic signals cannot enter the shielding room and the shielding room is not interfered by external electromagnetic signals. The problem that entering and exiting of large-scale
magnetic field equipment are inconvenient is solved by dismounting the doorsill whole body on the ground, so that the transportation and
carrying cost is reduced, and the carrying efficiency is improved.
