Embodiment 1

[0021] Embodiment 1: A cabin door inflatable sealing structure, such as figure 1 shown. This device comprises door frame 9, cabin door 10, and door frame and cabin door have bigger thickness. The periphery of the outer surface of the cabin door 10 extends outward to form an extension edge 13 , and a static sealing strip 14 is pasted on the circumference of the inner surface of the extension edge 13 . The inner middle part of the door frame 9 is provided with a groove 12 around the whole door frame 9, and an inflatable sealing strip 11 is arranged in the groove. When the inflatable sealing strip is deflated, the inflatable sealing strip shrinks in the groove. The bar bulges out of the groove against and squeezes on the side circumference of the cabin door.

[0022] Such as figure 2 , 3 , 4, the inflatable sealing strip 11 is a strip structure with double-layer airbags, which are respectively an outer airbag 1 and an inner airbag 2, the inner airbag is arranged inside the o...

Embodiment 2

[0025] Embodiment 2, a kind of inflatable sealing strip, such as Figure 5 shown. In this embodiment, the partition structure 3 of the inflatable sealing strip 11 is an oblique line arranged obliquely to the side of the inflatable sealing strip. The other structures are the same as in Embodiment 1. In actual operation, the outer airbags on both sides of the partition structure are obliquely pressed against each other, which can improve the sealing effect vertically and sideways of the sealing strip.

Embodiment 3

[0026] Embodiment 3, a kind of inflatable sealing strip, such as Figure 6 shown. In this embodiment, the partition structure 3 of the inflatable sealing strip 11 is bent twice at 90 degrees between the two sides of the inflatable sealing strip to form a broken line structure. The other structures are the same as in Embodiment 1. In actual work, the extrusion direction of the outer airbag at different positions of the partition structure is different, which can improve the sealing effect vertically and laterally of the inflatable sealing strip.

Abstract

The invention relates to an inflating sealing structure for a cabin door. The problem that the traditional cabin door sealing structure is greatly influenced by a closing force of the cabin door is solved. The device comprises a door frame and the cabin door which is embedded in the door frame under a closed state, wherein an extending edge is arranged on the periphery of the outer lateral surface of the cabin door; a static sealing strip is attached to the inner lateral surface of the extending edge; the inflating sealing structure is characterized in that a circle of slot is formed in the middle part of the inner lateral surface of the door frame by surrounding the whole door frame; an inflatable sealing strip is arranged in the slot; the inflatable sealing strip is provided with double-layer air bags, namely, an outer air bag and an inner air bag; the outer lateral wall of the outer air bag simultaneously serves as a sealing surface; the inner air bag is arranged in the outer air bag; the outer air bag and the inner air bag are respectively connected with the same inflating pipe through an air nozzle; during a working process, the outer air bag and the inner air bag keep the same air pressure; during a deflating process, the sealing surface is located in the slot; during an inflating process, the sealing surface is expanded out of the slot and is resisted against the lateral surface of the cabin door. According to the invention, the lateral inflating type sealing is adopted by the inflating sealing structure for the cabin door, so that the compressing sealing effect is ensured; when the air bag is damaged, a leaking position is indicated through a spraying position of coating, so that the leaking part can be quickly positioned and repaired.

Description

technical field [0001] The invention relates to a ship cabin door structure, in particular to an inflatable sealing structure for a cabin door. Background technique [0002] The cabins of ships are generally equipped with high-tightness cabin doors to ensure the sealing of the cabins. For example, in the cabins storing items that are susceptible to the influence of the sea surface environment, or refrigerated cabins, etc., the airtightness of the cabin doors has high requirements. The traditional cabin door usually has an extended edge on the outer periphery of the door panel, and a sealing strip is attached to the side of the extended edge close to the door. When the cabin door is closed, the cabin door body is embedded in the door frame, and the extended edge presses against the side wall at the outer end of the door frame. Above, a seal is formed between the extended edge and the outside wall of the door frame by a weatherstrip. This structure adopts positive compression...
