Description

Technical Field

[0001] The utility model belongs to the technical field of ship facilities, and in particular relates to a shutter for ships. Background Art

[0002] As is well known, ship windows commonly utilize sealed Venetian blinds. When open, these blinds allow air to flow through the blinds and prevent waves from entering the cabin. When closed, they seal the cabin and isolate moisture. Current Venetian blinds typically utilize a window frame and a louver cover, which is driven by a connecting rod and a cylinder. The louver cover is typically hinged to the window frame, which includes a structure for sealing with the louver cover. However, this sealing structure often obscures the ventilation area of ​​the window frame, resulting in the actual ventilation area of ​​the Venetian blind being determined by the window frame structure rather than the louver cover. Some Venetian blinds utilize a structure where adjacent louvers are connected end-to-end and abut against each other to achieve a shielding effect. However, these louver structures generally suffer from poor sealing performance and fail to meet the high airtightness requirements of ship windows.

[0003] In the existing technology, for example, the "A pneumatic wind and rain-tight shutter structure for ships with air-water separation function" disclosed in Chinese invention patent authorization publication number CN109441315B, and the "A waterproof gun shutter for ships" provided in Chinese invention patent authorization publication number CN111439340B, the former adopts a structure in which the shutter cover plate matches the window frame. This structure has good airtightness but a small ventilation area; while the latter adopts a structure in which the shutters are abutted against each other. This structure has a large ventilation area but poor airtightness. Therefore, both cannot meet the actual requirements of users.

[0004] In view of the above situation, it is necessary to design a ship shutter with simple structure, low cost, large ventilation area and good airtightness. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0008] In another specific embodiment of the present invention, the cross-section of the louver cover is a bullet-shaped structure with a larger upper portion and a smaller lower portion, the sealing strips are respectively embedded in the end of the louver cover with a larger cross-section and protrude from the end surface, and the sealing edge is formed on the end of the louver cover with a smaller cross-section and is formed as a rounded structure.

[0009] In another specific embodiment of the present invention, two ends of the louver cover plate are respectively formed with a louver cover plate shaft, and the louver cover plate shaft is rotatably supported on the two side walls of the window frame.

[0010] In another specific embodiment of the present invention, the louver cover has a rib on one end where the sealing strip is provided and on one side facing the cabin, extending away from the sealing edge. The ribs rest against the sealing edges of adjacent louver covers when the louver cover is in a closed state.

[0011] In another specific embodiment of the present invention, the louver cover is respectively formed with a drive plate on one side facing the cabin, the drive plate is respectively hinged on a connecting rod, the connecting rod is formed with a drive rod, one end of the cylinder is hinged to the window frame through a cylinder seat, and the other end is formed with a cylinder column hinged to the drive rod.

[0012] In a further specific embodiment of the present invention, the connecting rod and the driving rod are arranged in the shape of the letter "T".

[0013] In a more specific embodiment of the present invention, the window frame is formed with a circle of window frame fixing flange at the edge of one end facing the outside.

[0014] After adopting the above structure, the utility model has the beneficial effect: since adjacent louver covers are in the same plane and cooperate with each other through sealing strips and sealing edges to form a sealed connection structure, the louver covers do not need to rely on the window frame for sealing, which not only greatly increases the ventilation area, but also effectively improves the airtight effect.
