Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the fireproof and weathertight airtight door of the present invention comprises a door frame 3 and a door leaf, and an adjacent vertical edge of the door frame 3 and the door leaf is hinged together by a hinge 5 . A locking mechanism 1 is provided between the inner side of the door frame 3 and the door leaf. By pulling the handle of the locking mechanism 1, the door leaf and the door frame 3 can be in close contact and locked together. The non-hinged side of the door frame 3 and the door leaf is welded with a lock catch 2, by means of the door lock and the lock catch, the door leaf and the door frame 3 can be locked together. The door frame 3 is welded with a thick steel plate, and a groove is formed around the inner side of the door frame 3, and an inflatable air tire 9 is arranged in the groove, and the air tire is higher than the groove after being inflated. In addition, in order to achieve airtightness with the four sides o...

Abstract

The invention relates to a fireproof weathertight airtight door which comprises a door frame and a door leaf. Adjacent vertical sides of the door frame and the door leaf are hinged together. Locking mechanisms are arranged between the inner periphery of the door frame and the inner periphery of the door leaf. A lock catch is arranged on non-hinged sides of the door frame and the door leaf. An inflatable pneumatic tube is arranged at the inner periphery of the door frame. The door leaf comprises an inner board and an outer board. The inner board and the outer board are connected through a circular side board. The fireproof weathertight airtight door is characterized in that a projecting edge projecting to one side of the door frame is arranged on the periphery of the outdoor board of the door leaf, an inner turned edge is arranged at the outer edge of the projecting edge, and accordingly a groove is formed on one face of the projecting edge, which is adjacent to the door frame, and contains a flame-retardant rubber strip. An outer turned edge is arranged at the inner edge of the outer side of the door frame, and the outer turned edge tightly presses the flame-retardant rubber strip when the door leaf is closed. A fireproof strip is compounded to the circular side board on the periphery of the door leaf, and the outer edge of the fireproof strip is contacted with the inner edge of the flame-retardant rubber strip. The fireproof weathertight airtight door is airtight, fireproof and weathertight and has no application range limitations.

Description

technical field [0001] The invention relates to a cabin door for a ship. Specifically, it is a fireproof and weathertight airtight door for ships with fireproof and weatherproof properties, which is suitable for military ships and various civilian ships. Background technique [0002] It is well known in the shipbuilding industry that the airtight doors currently used on ships are only provided with air tires between the four sides of the door frame and the door leaf, and the airtight performance between the door frame and the door leaf is realized by inflating the air tires. In terms of fire performance, no measures have been taken. Therefore, the traditional airtight door has only airtight performance, but no fireproof performance and weathertight performance. This airtight door can only be used in occasions with airtight performance requirements, but cannot be used in occasions with fireproof performance and weathertight performance requirements, and the scope of use is ...
