Embodiment Construction
[0013] like figure 2 and image 3 As shown, the hinged pressure-resistant watertight door of the present invention includes a door frame 1 and a door panel 2, and one side of the door frame 1 and the door panel 2 is hinged together by means of a hinge. An inner convex edge 3 is processed around the outer edge of the door frame 1 , and the inner convex edge is formed by welding metal plates, and its thickness is greater than that of the door frame 1 . A frame is welded around the door panel 2 , and the perimeter of the frame protrudes outside the inside of the door panel 2 , so that an inward protrusion 5 is formed around the door panel 2 . The thickness of the inward protrusion 5 is equal to the thickness of the inner flange 3 of the door frame 1 .
[0014] A circumferential groove is processed on the outer surface of the inner flange 3 of the door frame 1, and a sealing strip 4 is embedded in the circumferential groove, and the sealing strip 4 protrudes outside the circumf...
