Description

Technical Field

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

[0002] Venetian blinds are one of the essential facilities on ships. They mainly serve to seal the cabin and block the waves. When opened, they can ventilate and prevent waves from entering the cabin. When closed, they can isolate the cabin from the outside environment. Current Venetian blinds do not have high requirements for sealing when closed. Most Venetian blinds do not have a sealing structure. In order to improve the sealing of the cabin and isolate the moisture from the sea, some Venetian blinds usually set sealing strips on the blades to improve the sealing. However, with the continuous improvement of ship design requirements, the sealing requirements of Venetian blinds have been put on the agenda. However, the existing structure of a single blade closing a sealing strip is not sufficient to meet the sealing requirements of the cabin. Water vapor and air will continue to penetrate into the cabin through the gap between the blade and the shutter frame.

[0003] In the existing technology, for example, the "Ship Shutter" provided by China Utility Model Patent Authorization Announcement No. CN206984267U includes a body, a plurality of gate assemblies, a connecting rod, and a cylinder assembly. The gate assembly is rotatably connected to the body, and the gate assembly is connected to the connecting rod, and the gate assembly is driven by the connecting rod to rotate synchronously. The connecting rod is connected to the cylinder assembly, and the connecting rod is driven by the cylinder assembly. This is also a relatively common shutter on the market, but the structure itself does not have sealing properties. Although technicians in this field can fully conceive of providing a sealing strip on the gate assembly to improve the sealing performance of the gate assembly when it is closed, this single-sealing structure cannot meet the sealing requirements on ships. If the original shutter structure is greatly modified to improve the sealing effect, the manufacturing cost of the shutter may increase, and this type of shutter cannot be modified.

[0004] In view of the above situation, it is necessary to design a sealing structure for ship shutters that is simple in structure, low in cost, can improve airtightness, and can be modified based on the original shutters. To this end, the applicant has made a useful design, and the technical solution to be introduced below was produced in this context. Utility Model Content

[0006] The task of the utility model is accomplished in this way. A sealing structure for a ship shutter comprises a window frame, a sealing plate arranged in the window frame, and a group of blade assemblies rotatably arranged in the window frame and spaced apart in the height direction. The sealing plate is provided with vents spaced apart in the height direction, and a circle of folded edges is formed around the vents toward one side of the blade assembly. When the blade assemblies are rotated and pressed against the folded edges, the shutter is in a closed state, and when the blade assemblies are rotated away from the folded edges, the shutter is in an open state. The blade assemblies are respectively driven to rotate by a driving rod, and are characterized in that: the blade assembly comprises a cover plate, and a circle of embedded grooves is formed on one edge of the cover plate facing the sealing plate, and the position of the embedded grooves corresponds to the position of the folded edges. A first sealing strip is respectively embedded in the embedded grooves, and a spacing groove is respectively formed between the folded edges of two adjacent vents, and a second sealing strip is respectively provided in the spacing grooves. When the blade assembly is in the closed state, its first sealing strip respectively abuts against the corresponding folded edges and its two side edges in the front-rear direction respectively abut against the second sealing strip.

[0007] In a specific embodiment of the present invention, a window frame cavity is formed in the window frame, which is through to the left and right. The sealing plate is arranged in the window frame cavity and separates the window frame cavity. The four sides of the sealing plate are respectively welded to the four sides of the inner wall of the window frame cavity.

[0008] In another specific embodiment of the present invention, one side edge of the window frame is folded outward to form a flange edge.

[0009] In another specific embodiment of the present invention, the four peripheral edges of the cover plate all protrude from the folded edges in the closed state.

[0010] In another specific embodiment of the present invention, the upper ends of the front and rear sides of the cover plate are respectively formed with a hinge shaft, the hinge shaft is rotatably arranged on the front and rear side walls of the window frame, and the cover plate rotates around the hinge shaft.

[0011] In another specific embodiment of the present invention, a driving arm is fixed to each side of the cover plate facing the sealing plate, and one end of the driving arm passes through the corresponding vent and is hinged to the driving rod.

[0012] In another specific embodiment of the present invention, the driving rod moves up and down through the driving mechanism to pull the driving arm to rotate the cover plate around the hinge axis; the driving rod is provided with a driving rod push-pull plate, one end of the driving rod push-pull plate is connected to a cylinder, the lower end of the cylinder is hinged to the cylinder seat, the cylinder seat is fixed on the window frame, and one end of the cylinder column of the cylinder is hinged to the driving rod push-pull plate.

[0013] In a further specific embodiment of the present invention, the number of the blade assemblies is the same as the number of the vents and they correspond to each other one by one.

[0014] The utility model has the beneficial effect of adopting the above structure: since the blade assembly and the sealing plate are transformed into a double-channel sealing structure based on the original shutter, the air tightness of the shutter is effectively improved, while reducing the manufacturing and transformation costs.
