Description

Technical Field

[0001] The utility model belongs to the technical field of ship cabin parts, and more specifically, relates to an openable and closable louver structure. Background Technique

[0002] Windows are generally required to be provided on ship cabins. Due to installation space limitations, the windows are made into upward-opening type or upward-opening with diagonal bracing plate type. However, because the large-size windows on ships are heavy, it is quite laborious for adults to open or close them, and the sealing is often not reliable after the windows are closed.

[0003] In the prior art, there is a technology with the name of "a hinge-linked rotating louver" and the publication (announcement) number of "CN110185370A". This technology discloses a hinge-linked rotating louver, including a window frame, a window sash, an upper hinge and a lower hinge. The window sash is arranged on the window frame. There are multiple window sashes, and there are multiple upper hinges and multiple lower hinges. One end of the upper hinge is connected to the upper end of the window sash, and the other end is connected to the window frame. One end of the lower hinge is connected to the upper end of the window sash, and the other end is connected to the window frame. Multiple upper hinges are connected by a first push rod, and multiple lower hinges are connected by a second push rod. Both the first push rod and the second push rod are in the shape of thin sheets. When an external force acts on the window sash, the acting force is transmitted through the first push rod and the second push rod, facilitating the opening and closing of each window sash; by providing upper and lower hinges, the load-bearing function of the window sash can be realized. The first push rod and the second push rod mainly play the role of transmitting the external acting force, greatly reducing the requirement for the strength of the push rod and reducing the thickness of the push rod, so that when the window sash is closed, good sealing performance can be achieved and the integrity can be improved.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: aiming at the deficiencies of the prior art, to provide an openable and closable louver structure with a simple structure, which can realize opening and closing control conveniently, quickly and labor-savingly, and at the same time has good sealing effect after closing, effectively meeting the use requirements of ships.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is as follows:

[0007] The utility model is an openable and closable louver structure, including a window frame and a cover plate. The window frame and the cover plate are connected by hinges, and are connected by heavy-duty hydraulic struts between the window frame and the cover plate. Two heavy-duty hydraulic struts are provided, and one is provided on each side surface. When the cover plate is opened, it is supported by the heavy-duty hydraulic struts, and when the cover plate is closed, it is pulled by the heavy-duty hydraulic struts. A louver frame is installed inside the window frame, louvers are arranged inside the louver frame, and a protective net is installed in front of the louvers.

[0008] A plurality of cover reinforcement ribs are arranged at a position near the edge on the outer side of the cover plate.

[0009] The upper part of the window frame and the upper part of the cover plate are movably connected by a hinge.

[0010] Sealing strips are arranged around the inside of the cover plate.

[0011] One end of the heavy-duty hydraulic gas strut is connected to the inner side of the window frame through a window frame strut swivel joint, and one end of the heavy-duty hydraulic gas strut is connected to the inner side of the cover plate through a cover plate strut swivel joint. The heavy-duty hydraulic gas struts are respectively connected to each side of the window frame and each side of the cover plate.

[0012] The fixed screw buckle of the cover plate is movably hinged on the hull plate member, and after the cover plate is opened, it is set to a structure that can be fixed by the fixed screw buckle of the cover plate.

[0013] The screw buckle and the pressing plate assembly include a swivel bolt and an annular nut, and a pressing plate on the cover plate. One end of the swivel bolt is movably connected to the lower part of the window frame, and the annular nut is screwed onto the swivel bolt.

[0014] The protective net is located on the window frame near the cover plate side.

[0015] A plurality of screw buckles and pressing plate assemblies are arranged at intervals along three sides of the outer circles of the cover plate and the window frame.

[0016] The working principle and beneficial effects of adopting the technical solution of the present utility model are as follows:

[0017] For the openable and closable louver structure described in the present utility model, a window frame is installed on the bulkhead of the cabin, and the window frame and the cover plate are connected by a hinge. Since the cover plate is heavy and difficult to open or close manually, the window frame and the cover plate are connected by a heavy-duty hydraulic gas strut. By means of the thrust of the hydraulic gas strut, the operator can conveniently and reliably control the extension and contraction of the heavy-duty hydraulic gas strut. When extending, the cover plate is opened relative to the window frame, and when contracting, the cover plate is closed relative to the window frame. After the cover plate is closed, the screw buckles and pressing plates on three sides ensure that the cover plate fits tightly against the window frame, ensuring that it is closed in place and improving the sealing effect when the louver is closed. A louver frame is installed inside the window frame, and louver blades are arranged inside the louver frame, and a protective net is installed in front of the louver blades. The cover plate can be opened for ventilation or closed for sealing, and the blades can be opened or closed. When the cover plate is opened, the protective net is used to prevent insects and rats, ensuring that the cabin is not affected by insects or rats. Description of the Drawings

The window frame 3 includes a shutter frame 8, and a shutter blade 6 and a protective net 7 are arranged inside the inner circle of the shutter frame 8. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When the structure is set up, the window frame 3 is installed on the cabin wall of the ship's cabin. The window frame 3 and the cover plate 5 are connected by a hinge. Since the cover plate 5 is heavy, it is not easy to open or close by manpower. The window frame 3 and the cover plate 5 are connected by a heavy-duty hydraulic gas strut 10. By means of the thrust of the hydraulic gas strut 10, the operator can conveniently and reliably control the extension and contraction of the heavy-duty hydraulic gas strut 10 to realize the opening and closing control of the cover plate. When the heavy-duty hydraulic gas strut 10 extends, the cover plate 5 is opened relative to the window frame 3. When the heavy-duty hydraulic gas strut 10 contracts, the cover plate 5 is closed relative to the window frame 3. After the cover plate 5 is closed, the spiral buckle and the pressing plate on three sides ensure that the cover plate reliably fits the window frame 3, ensuring that the cover plate 5 is closed in place and improving the sealing effect when the shutter is closed. A shutter frame 8 is installed inside the window frame 3, shutter blades 6 are arranged inside the shutter frame 8, and a protective net 7 is installed at the outer side position of the shutter blades 6. The cover plate 5 can be opened for ventilation or closed for sealing. The shutter blades 6 can be opened or closed. When the cover plate is opened, the protective net is used to prevent insects and rats, ensuring that the cabin is not affected by insects or rats. The openable and closable shutter structure described in the utility model has a simple structure, can conveniently, quickly and labor-savingly realize the opening and closing control, and has a good sealing effect after closing, effectively meeting the use requirements of the ship.

[0025] Multiple cover plate strengthening ribs 2 are arranged at the position close to the edge on the outer side of the described cover plate 5, and spiral buckles and pressing plates 9 are arranged on three sides of the cover plate 5 and the window frame 3. For the above structure, the cover plate strengthening ribs 2 are used to reliably strengthen the overall strength of the cover plate and prevent deformation easily; spiral buckles and pressing plates are arranged on three sides of the cover plate and the window frame to ensure that the cover plate 5 can be reliably closed.

[0026] The upper part of the described window frame 3 and the upper part of the cover plate 5 are movably connected by a hinge 1. For the above structure, through the hinge connection, the cover plate can move relative to the window frame to realize the opening or closing control.

[0027] A filler strip 4 is arranged inside the described cover plate 5, and an aging-resistant chloroprene rubber sealing strip 4 is arranged at the contact surface between the cover plate 5 and the window frame to ensure the sealing of the cover plate 5 against external wind and rain after closing.

[0028] One end of the heavy-duty hydraulic gas strut 10 is connected to the inner side of the window frame 3 through the window frame strut joint head 12, and one end of the heavy-duty hydraulic gas strut 10 is connected to the inner side of the cover plate 5 through the cover plate strut joint head 11. Each side of the window frame 3 and each side of the cover plate are respectively connected with the heavy-duty hydraulic gas strut 10. The above structure reliably realizes the connection between the heavy-duty hydraulic gas strut 10 and the window frame and the cover plate 5 through the window frame strut joint head 12 and the cover plate strut joint head 11, and when the heavy-duty hydraulic gas strut 10 pushes the cover plate 5 to open or close, the angle between the heavy-duty hydraulic gas strut 10 and the cover plate 5 and the window frame 3 can change, effectively meeting the actual demand for the state change of the cover plate 5 when it is opened and closed.

[0029] The spiral buckle and the spiral buckle of the pressure plate assembly 9 are movably hinged at the lower part of the window frame 3, and the pressure plate of the spiral buckle and the pressure plate assembly 9 is installed on the cover plate 5. The spiral buckle and the pressure plate assembly 9 includes a movable bolt 14 and a ring nut 15, and a pressure plate on the cover plate 5. One end of the movable bolt 14 is movably connected to the lower part of the window frame 3, and the ring nut 15 is screwed on the movable bolt 14. With the above structure, when the cover plate 5 needs to be opened, the ring nut 15 is first loosened, and then the spiral buckle is flipped out of the slot of the pressure plate at the lower part of the cover plate 5. A small lifting force is applied to the cover plate by manpower. With the help of the thrust of the hydraulic gas strut 10, the cover plate 5 can be easily opened. After the cover plate 5 is fully opened, the spiral buckle 13 fixing the cover plate is flipped into the slot of the pressure plate at the lower part of the cover plate 5, and the ring nut 15 of the spiral buckle 13 fixing the cover plate is loosened. When the cover plate 5 needs to be closed, first loosen the ring nut 15 of the cover plate fixing spiral buckle 13, flip the cover plate 5 fixing spiral buckle 13 out of the slot of the upper pressure plate 17 of the cover plate 5, and realize the positioning of the opened cover plate 5, avoid the shaking of the cover plate due to the turbulence of the ship, and ensure the stability of the cover plate in the open state. When the cover plate needs to be closed, flip the cover plate fixing spiral buckle 13 out of the slot of the pressure plate at the bottom of the cover plate 5, apply a small downward pressure to the cover plate 5 by manpower, and then close the cover plate 5, and then flip the spiral buckle into the slot of the pressure plate 17 at the bottom of the cover plate 5, and the movable bolt 14 is clamped in the slot of the pressure plate 17 at the bottom of the cover plate 5, and then tighten the ring nut 15, reliably apply force on the cover plate 5, ensure that the cover plate 5 reliably fits the window frame 3, and achieves reliable sealing and improves the sealing effect.

[0030] The cover plate fixing spiral buckle 13 is movably hinged on the hull plate 16, and the cover plate 5 is set to be fixed by the cover plate fixing spiral buckle 13 after opening. In the above structure, because the ship is frequently bumpy during travel, and even has a large roll angle, in order to ensure the reliability when opening, the cover plate is hooked and fixed by the cover plate fixing spiral buckle 13 connected to the hull plate.

[0031] The spiral buckle and the pressure plate 9 include a ring nut and a pressure plate on the cover plate. One end of the movable bolt is movably connected to the lower part of the window frame, and the ring nut is screwed on the movable bolt.

In the above structure, each spiral buckle and pressure plate assembly 9 includes a spiral buckle and a pressure plate, and the arrangement of a plurality of spiral buckles and pressure plate assemblies 9 applies force to the cover plate 5 from different positions to ensure that the cover plate is reliably closed.

[0033] The openable and closable shutter structure described in the utility model has a window frame 3 installed on the bulkhead of the cabin, and the window frame 3 and the cover plate 5 are connected by a hinge. Because the cover plate 5 is heavy and difficult to open or close by manpower, the window frame 3 and the cover plate 5 are connected by a heavy hydraulic gas strut 10. By using the thrust of the hydraulic gas strut 10, the operator can conveniently and reliably control the extension and retraction of the heavy hydraulic gas strut 10 to realize the opening and closing control of the cover plate 5. When the heavy hydraulic gas strut 10 is extended, the cover plate 5 is opened relative to the window frame 3, and when the heavy hydraulic gas strut 10 is retracted, the cover plate 5 is closed relative to the window frame 3. After the cover plate 5 is closed, the spiral buckles and the pressure plate assembly 9 on three sides ensure that the cover plate 5 is reliably attached to the window frame 3, ensuring that the cover plate 5 is closed in place, and improving the sealing effect when closed. A shutter frame 8 is installed inside the window frame 3, and shutter blades 6 are arranged inside the shutter frame 8. A protective net 7 is installed at the outer position of the shutter blades 6. The cover plate 5 can be opened to realize ventilation, and can also be closed to realize closure. The shutter blades 6 can be opened or closed. When the cover is open, the protective net is used to prevent insects and rodents, ensuring that the cabin is not affected by insects or rats.

[0034] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
