Description

Technical Field

[0001] The utility model belongs to the technical field of ship facilities, and particularly relates to a quick-opening and -closing louver for ships. Background Art

[0002] As is well known, the windows on ships generally use louvers with a sealing function. When opened, they can allow air to pass through the louver blinds, and at the same time prevent large waves from entering the cabin. When closed, they can seal the cabin to isolate water vapor. The existing louvers often adopt a structure in which the louver blinds are matched with a sealing cover. The sealing cover is supported by a support member when opened and fixed by a lock body when closed. The main disadvantages of the above structure are as follows: First, since the sealing cover is generally heavy, it is very strenuous to lift it up when opening. Second, the locking structure is relatively cumbersome to operate. Therefore, the operator rarely uses the lock body in actual use. However, when the sealing cover is closed and not fixed by the lock body, the sealing cover will open and close due to the lack of restraint as the hull swings.

[0003] In the prior art, such as the "hatch cover louver for a ship" provided by the Chinese invention patent application publication number CN111169594A, which supports the hatch cover through a pair of support arms; and for another example, the "support device for a ship louver" disclosed by the Chinese utility model patent authorization publication number CN205225025U, which supports the cover plate through a support rod. Both adopt the above support structure and also have the above-mentioned disadvantages.

[0004] In view of the above situation, it is necessary to design a quick-opening and -closing louver for ships with a simple structure and low cost, which can save effort when opening the sealing cover and achieve self-locking when closing. Therefore, the applicant has made a beneficial design, and the technical solution to be introduced below is generated under this background. Summary of the Utility Model

[0005] The task of the utility model is to provide a quick-opening and -closing louver for ships, which helps to improve the support and self-locking structure of the sealing cover, so that the sealing cover is labor-saving when opened and can effectively restrain the opening and closing of the sealing cover following the swing of the hull, which is beneficial to the quick opening and closing of the louver.

[0006] The task of the present utility model is completed as follows. A quick-opening and closing louver for a ship includes an outer frame body connected to the ship's cabin wall, a louver curtain disposed inside the outer frame body and close to the side of the ship's cabin, and a sealing cover hinged at the upper end to the outer frame body and covering the outer side of the outer frame body facing the outside of the ship's cabin. The characteristics are: at least one gas spring is provided between the outer frame body and the sealing cover. The gas spring is compressed when the sealing cover is in the closed state. At this time, an included angle α is formed between the pushing direction of the gas spring and the horizontal reference plane, and the range of the included angle α is 95° to 110°. The gas spring is released when the sealing cover is in the open state. At this time, an included angle β is formed between the pushing direction of the gas spring and the horizontal reference plane, and the range of the included angle β is 30° to 50°.

[0007] In a specific embodiment of the present utility model, an outer frame cavity for communicating the inside of the ship's cabin with the outside is formed inside the outer frame body, and the louver curtain is disposed on the side close to the inside of the ship's cabin within the outer frame cavity.

[0008] In another specific embodiment of the present utility model, a pair of sealing cover connecting plates are fixed at the upper end of the outer frame body. At positions corresponding to the sealing cover connecting plates on the upper edge of the sealing cover, a sealing cover hinge ear is respectively formed. The sealing cover hinge ears and the corresponding sealing cover connecting plates are respectively hinged to each other through a hinge shaft.

[0009] In still another specific embodiment of the present utility model, one end of the gas spring forms a gas spring column, and the other end forms a gas spring hinge ear. At least one gas spring column hinge seat is fixed on the side of the sealing cover facing the outer frame body. The end portions of the gas spring columns are respectively hinged to the corresponding gas spring column hinge seats. At least one gas spring hinge ear connecting seat is fixed on the inner side wall of the outer frame body. A gas spring hinge seat extending below the corresponding gas spring is respectively formed on the gas spring hinge ear connecting seat. The gas spring hinge seats are respectively hinged to the corresponding gas spring hinge ears.

[0010] In yet another specific embodiment of the present utility model, a sealing ring is provided at the position where the sealing cover contacts the outer frame body in the closed state.

[0011] In still another specific embodiment of the present utility model, at least one lock plate is provided at the lower end of the outer frame body. A lock rod is hinged on the lock plate. A locking nut is threadedly connected to the lock rod. A lock tongue is respectively fixed on the sealing cover corresponding to the position of the lock rod. After the lock rod rotates and is inserted into the lock tongue, the locking nut is tightened so that the locking nut abuts and presses against the lock tongue.

[0012] After the utility model adopts the above structure, the beneficial effects are as follows: Since the structure that changes the pushing direction of the gas spring to change the force application direction of the gas spring on the sealing cover is adopted, when the sealing cover is opened, the gas spring can assist to achieve the effect of labor-saving opening, and when it is closed, the gas spring can apply a reverse force to pull the sealing cover, so as to achieve the effect of self-locking, avoid the opening and closing of the sealing cover due to the swing of the hull, and facilitate the quick opening and closing of the shutter.

[0018] Please refer to Figure 1 and in conjunction with Figure 2 , the present utility model relates to a fast-opening and -closing shutter for a ship, which includes an outer frame body 1 connected to the ship's cabin wall, a louver curtain 2 arranged inside the outer frame body 1 and close to the ship's cabin side, and a sealing cover 3 hinged to the upper end of the outer frame body 1 and covering the outer side of the outer frame body 1 facing the ship's cabin

[0019] The technical innovation point of the present utility model lies in that: at least one gas spring 4 is arranged between the outer frame body 1 and the sealing cover 3. The number of the gas springs 4 is preferably two. The gas springs 4 are compressed when the sealing cover 3 is in the closed state. At this time, an included angle α is formed between the pushing direction of the gas spring 4 and the horizontal reference plane, and the range of the included angle α is 95° to 110°. The gas springs 4 are released when the sealing cover 3 is in the open state. At this time, an included angle β is formed between the pushing direction of the gas spring 4 and the horizontal reference plane, and the range of the included angle β is 30° to 50°. In this embodiment, the included angle α is preferably 100°, and the included angle β is preferably 45°.

[0020] An outer frame cavity 11 for communicating the interior of the ship's cabin with the outside is formed in the outer frame body 1, and the shutter 2 is arranged on the side close to the interior of the ship's cabin in the outer frame cavity 11.

[0021] A pair of sealing cover connecting plates 14 are fixed at the upper end of the outer frame body 1. Sealing cover hinge ears 31 are respectively formed at the positions corresponding to the sealing cover connecting plates 14 on the upper edge of the sealing cover 3. The sealing cover hinge ears 31 and the corresponding sealing cover connecting plates 14 are respectively hinged to each other through a hinge shaft 311.

[0022] One end of the gas spring 4 is formed with a gas spring column 41, and the other end is formed with a gas spring hinge ear 42. At least one gas spring column hinge seat 32 is fixed on the side of the sealing cover 3 facing the outer frame body 1. The end parts of the gas spring columns 41 are respectively hinged to the corresponding gas spring column hinge seats 32. At least one gas spring hinge ear connecting seat 12 is fixed on the inner side wall of the outer frame body 1. A gas spring hinge seat 121 extending below the corresponding gas spring 4 is respectively formed on the gas spring hinge ear connecting seat 12. The gas spring hinge seats 121 are respectively hinged to the corresponding gas spring hinge ears 42. In this example, the number of the gas spring column hinge seats 32 and the gas spring hinge ear connecting seats 12 is the same as that of the gas springs 4 and is two.

[0023] A sealing ring 33 is arranged at the position where the sealing cover 3 contacts the outer frame body 1 in the closed state.

[0024] At least one lock plate 13 is arranged at the lower end of the outer frame body 1. A lock rod 131 is hinged on the lock plate 13. A locking nut 1311 is threadedly connected to the lock rod 131. Lock tongues 34 are respectively fixed on the sealing cover 3 corresponding to the positions of the lock rods 131. After the lock rod 131 rotates and is inserted into the lock tongue 34, the locking nut 1311 is tightened so that the locking nut 1311 abuts against and presses on the lock tongue 34. In this embodiment, the number of the lock plates 13 is preferably two.

[0025] Please refer to Figure 1 And in combination withFigure 2 , describe the working principle of the present utility model: As Figure 1 shown, when the shutter is in the closed state, the pushing direction of the air spring column 41 of the aforementioned air spring 4 is biased towards the inside of the ship's cabin. The air spring column 41 pulls the sealing cover 3 through the air spring column hinge seat 32. At this time, the sealing ring 33 on the sealing cover 3 abuts against the outer edge of the outer frame body 1, thereby realizing the self-locking action of the sealing cover 3; when it is necessary to completely close the aforementioned sealing cover 3, rotate the aforementioned lock lever 131 to make the lock lever 131 snap into the lock tongue 34, and then tighten the locking nut 1311 to press against the lock tongue 34, thereby realizing the manual locking of the sealing cover 3; when it is necessary to open the shutter, first open the aforementioned sealing cover 3 to make the sealing cover 3 rotate around the hinge shaft 311. During the rotation of the aforementioned sealing cover 3, since the pushing direction of the air spring column 41 of the air spring 4 changes and faces the outside of the ship's cabin, the air spring column 41 pushes the sealing cover 3 to open counterclockwise through the air spring column hinge seat 32 and supports the sealing cover 3, thereby realizing the purpose of labor-saving opening, as Figure 2 shown in the position.
