The present invention relates to a door frame installed on the opening to enable people to come in and go out and a watertight sliding door which opens and closes the opening as a door slides by a hydraulic pressure or an air pressure along a guide rail installed on the front surface of the upper and lower portions of the door frame from side to side. More specifically, the watertight sliding door is provided with inclined surfaces respectively on the front surface of the upper and lower portions of the door frame and a rear surface of the door coming into contact with the front surface. One inclined surface is formed at the front surface of the upper and lower portions of the door frame and protrude forward to face in a direction where a door is closed, and the other inclined surface is formed at the rear surface of the upper and lower portions of the door and protrudes in an opposite direction to the inclined surfaces of the door frame to come into contact with the inclined surface of the door frame. As such, the inclined surface is formed at the front surface of the upper and lower portions of the door frame and protrudes forward to face in a direction where the door is closed and the inclined surface of the door is formed to correspond to the inclined surface of the door frame, wherein the inclined surfaces are formed to have alternate exterior and interior angles, respectively, thereby preventing wear-off of the sealing as the sealing is not in contact with the door frame and only pressed at the clamping moment, with a significant sealing effect with a tight sealing of the door to the door frame.

    본 발명 내외부로 왕래하는 입구에 설치되는 문틀프레임과, 상기 문틀프레임의 상·하부의 전면에 좌우방향으로 설치된 가이드레일을 따라 유압 또는 공압에 의해 도어가 슬라이딩 됨으로써 입구를 개폐하는 수밀 슬라이딩 도어에 관한 것으로서, 더욱 상세하게는 상기 문틀프레임의 상·하부 전면과 문틀프레임의 상·하부 전면에 접촉하는 도어의 후면에는 각각 경사면이 형성되어 있되, 상기 문틀프레임의 상·하부 전면에는 도어가 닫히는 방향을 향하도록 전방으로 더 돌출되는 형상의 경사면이 형성되고, 상기 문틀프레임의 경사면에 접촉하도록 도어의 상·하부 후면에는 문틀프레임의 경사면의 방향과 반대방향으로 돌출하도록 경사면이 형성되어 있는 것이 특징인 수밀 슬라이딩 도어에 관한 것이다. 따라서, 문틀프레임의 상·하부 전면에 형성된 경사면이 도어의 닫히는 방향을 향하도록 전방으로 더 돌출되도록 형성되고, 이에 대응하는 도어면의 경사면이 서로 엇각면을 이루도록 형성됨으로써 도어의 이동시에는 실링이 문틀프레임에 접촉하지 않고 클램핑 되는 순간 실링이 압박되는 구조이기에 실링의 마모가 거의 없으며, 이로 인해 도어는 문틀프레임에 더욱 긴밀하게 수밀이 유지될 수 있다는 등의 현저한 효과가 있다.
