Soundproofing and noise reduction sealed security door

Abstract

The utility model relates to security door technical field especially relates to a sound insulation and noise reduction sealed security door, including door frame, door body, sealing rubber ring and reinforcing sealing mechanism, the inside hinged of door body in door frame is equipped with the first wedge surface ring with fixed installation, the corresponding side fixed mounting of door body is equipped with the second wedge surface ring, the first wedge surface ring and the second wedge surface ring are wedge surface cooperation structure, the sealing rubber ring is embedded in the wedge surface surface of first wedge surface ring, reinforcing sealing mechanism sets up between the first wedge surface ring and the second wedge surface ring, the utility model discloses through the wedge surface cooperation of first wedge surface ring and the second wedge surface ring, when the door body is in closed state, can form continuity surface contact structure in the door frame and door body contact interface, can effectively promote the compression deformation variable of sealing rubber ring, strengthens the sealing performance, changes simultaneously through the wedge surface structure sound wave transmission path, restrains the direct spread of sound through the clearance between door frame and door body, realizes the promotion of sound insulation performance.
