Embodiment Construction
[0014] like figure 1 and figure 2 As shown, the steel weathertight door without threshold of the present invention includes a door frame 5 and a door panel 6, and the door frame 5 is an inverted U-shaped door frame, that is, the door frame 5 is connected by two vertical frames and two ends connected to the upper ends of the two vertical frames. The upper frame together is formed, and sealing strip 16 is all provided with between the two vertical frames of door frame 5 and the corresponding edge of upper frame and door panel 6, and the lower limit of door panel 6 is also provided with sealing strip. In this way, in the closed state, between the upper frame of the door panel 6 and the upper frame of the door frame 5, between the two vertical frames of the door frame 5 and the two corresponding vertical edges of the door panel 6, and between the lower edge of the door panel 6 and the corresponding ship deck. .

The invention relates to a steel weather tight door without a threshold. The door comprises a door frame and a door plate, wherein sealing strips are arranged among the edges between the door frame and the door plate, the same vertical sides of the door frame and the door plate are hinged, and a locking nose is arranged between the other same vertical sides of the door frame and the door plate. The door is characterized in that the door frame is an inverse U-shaped door frame. Hinges contain an upper hinge and a lower hinge, the upper hinge and the lower hinge are respectively provided with two pin ears which are fixed with the door frame together, and one vertical rotating shaft is respectively arranged between every two pin ears. Rotating arms are respectively arranged between the rotating shafts and the neighboring door plate, vertical holes are formed in one ends of the rotating arms, one ends of the rotating arms are sleeved on the corresponding vertical rotating shafts by the vertical holes, and the other ends of the rotating arms are fixed on the door plate. Lifting mechanisms which are convenient for the door plate to move up and down are arranged among the hinged sides between the door frame and the door plate. The weather tight door is provided with the threshold and does not pass delaying obstacles. Besides, the occasions with the requirement of fast pass without obstacle can be satisfied, and the usage occasions cannot be limited. The steel weather tight door is suitable for ship cabins with the requirements of no obstacles and fast pass.
Description
technical field [0001] The invention relates to a hermetic door. Specifically, it is a steel weathertight door without threshold for ships with windproof and rainproof performance. It is especially suitable for occasions requiring barrier-free fast passage. Background technique [0002] At present, most of the weathertight doors on ships adopt the following structure, that is, the weathertight doors include a door frame and a door panel, a sealing strip is provided between the edge of the door frame and the door panel, and the same vertical edge of the door frame and the door panel is hinged together. A lock nose for locking the door is installed between the door frame and another same vertical edge of the door panel. Wherein, the door frame is rectangular, that is, there is a threshold at the bottom of the door frame. Although the cabin door adopting the above-mentioned structure has a weathertight function, because its door frame is rectangular and has a threshold, it h...
