The utility model discloses an anti-
radiation door with a multiple linkage sealing function, which relates to the technical field of anti-
radiation doors and comprises a fixed bottom plate, a
supporting wall is fixedly mounted at the top of the fixed bottom plate, a sealing door is movably mounted on one side of the
supporting wall, and a mounting door groove is formed in the
supporting wall. Through mutual cooperation of the sliding block, the track plate, the supporting plate, the supporting frame, the movable frame, the sealing door, the mounting door, an L-shaped sliding groove, a roller groove, a movable groove, a
threaded rod, a motor, a threaded sleeve block and a movable frame, the problem that harmful radioactive rays penetrate through a gap between the
radiation-proof door and a door frame in the using process of the radiation-proof door, so that leakage is caused, and the service life of the radiation-proof door is prolonged is solved. The anti-radiation door has the advantages that the problems of poor
shielding effect and influence on
physical health of personnel due to the fact that the anti-radiation door is arranged in the anti-radiation door are solved, the anti-radiation door is effectively sealed and closed, gaps between door frames are prevented from penetrating out, the
shielding effect is good, and the practicability of the device is improved.
