The closing action is reversed, i.e. the door body 1 is slid first into place, and the door body 1 swings in the opposite direction to the opening direction, so that the rollers 31 rotate into the slide grooves 61 of the rail frame 6.
The watertight door can be opened by a driving device, namely, a flat pulling action, and the watertight door can swing and then slide step by a mechanical device, so that the cost is effectively saved, and the reliability of the watertight door is improved.
In summary, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention without departing from the above technical solution of the present invention still falls within the scope of the technical solution of the present invention.
