Description

Technical Field

[0001] This utility model belongs to the technical field of lifeboat hatch doors, specifically relating to a sealed hatch door structure for a fully enclosed lifeboat. Background Technology

[0002] Cargo ships and oil tankers are required to be equipped with fully enclosed lifeboats for abandon ship operations. To ensure the crew's safety and rapid response, regular emergency drills are necessary. During these drills, crew members should learn how to quickly open the hatches of the fully enclosed lifeboats and enter. Existing fully enclosed lifeboat hatches often have multiple levers to ensure complete sealing. However, during emergency drills, crew members must turn each lever individually to open the hatch. Since each lever operates independently and cannot be linked, this results in prolonged opening times and reduced escape speed. Furthermore, after crew members enter the lifeboat and close the locked hatch, the lifeboat may rock violently on the water, causing the levers to gradually turn and eventually lose their lock, compromising the seal and the lifeboat's seal. Utility Model Content

[0003] The purpose of this invention is to provide a sealed hatch structure for a fully enclosed lifeboat, so as to solve the problems of cumbersome opening process and the lock handle turning due to lifeboat swaying in the existing sealed hatch structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sealed hatch structure for a fully enclosed lifeboat includes a door frame and a door panel. A door hinge connects the door frame and the door panel. A limit frame is slidably connected to the inner side of the door panel. Two first lock handles and two second lock handles are rotatably connected to the door panel. Each of the two first lock handles and the two second lock handles includes a pivot that rotates through the door panel and two handles fixed at both ends of the pivot. Limit rods are fixedly installed on the four handles located on the inner side of the door panel. The limit frame has grooves that slidably engage with the multiple limit rods.

[0006] Preferably, two first guide rods are fixedly installed on one side of the limiting frame and slidably connected to the door panel. A top plate is fixedly installed at one end of the two first guide rods. A second guide rod is fixedly installed on the door panel. A slider is slidably connected to the outside of the second guide rod. A first connecting rod is rotatably connected between the slider and the top plate.

[0007] Preferably, a rotating handle is rotatably connected to the slider, a buckle is rotatably connected to the rotating handle at an eccentric position, and a hook that cooperates with the buckle is fixedly installed on the door panel.

[0008] Preferably, the two first lock handles are symmetrically distributed at the upper and lower ends of the door panel, and the two second lock handles are vertically distributed at the end of the door panel away from the door hinge. Lock handles are fixedly installed on the rotating shafts of the two first lock handles and the two second lock handles. Multiple slots are provided in the door frame to slide and engage with the multiple lock handles respectively. The multiple slots are all quarter-circular structures.

[0009] Preferably, the lock handle on the first lock handle is collinear with the corresponding handle, and the lock handle on the second lock handle is perpendicular to the corresponding handle.

[0010] Preferably, a fixing plate is fixed on the rotating shaft of each of the two first lock handles and the two second lock handles, and a slide rod is fixedly installed on each of the four fixing plates. Two slide plates are symmetrically slidably connected inside the door panel. Each of the two slide plates has a U-shaped groove that slides with the slide rod. A slide frame is fixedly connected between the two slide plates, and the slide frame is slidably connected to the door panel.

[0011] Preferably, both of the sliding plates are provided with sliding grooves, and two fixing rods are fixedly provided on the door panel, with the two fixing rods slidingly engaged in the two sliding grooves respectively.

[0012] Preferably, a rotating frame is rotatably connected to the door panel, and a second connecting rod is rotatably connected between the rotating frame and one end of the slide.

[0013] Preferably, a plurality of springs are fixedly connected between the carriage and the door panel.

[0014] Preferably, a sealing strip is fixedly installed on the door panel, and a U-shaped sealing groove for wrapping the sealing strip is fixedly installed on the door frame.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) This utility model is equipped with a limiting frame and a limiting rod. After the crew enters the lifeboat and turns the two first lock handles and the two second lock handles to close the hatch, the limiting frame slides on the inside of the door panel so that the groove on the limiting frame abuts against the four limiting rods, thereby limiting the two first lock handles and the two second lock handles, preventing the first lock handles and the second lock handles from being affected by the shaking of the lifeboat, and ensuring the closure of the lifeboat.

[0017] (2) As described above, when the limiting frame slides against the limiting rod, the slider moves to the top of the second guide rod under the action of the first connecting rod. At this time, the buckle is put on the outside of the hook and the handle is rotated so that the buckle and the hook are tightly engaged, thereby fixing the slider and limiting the sliding of the limiting frame.

[0018] (3) This utility model is equipped with a sliding plate, a sliding frame, a second connecting rod, a rotating frame, and a spring. When the door needs to be opened, the rotating frame is pulled to rotate on the outside of the door panel. The rotation causes the sliding frame to slide inside the door panel and compress the spring through the second connecting rod. At the same time, the sliding frame drives the two sliding plates to slide, so that the U-shaped groove on the sliding plate drives the sliding rod to move, thereby realizing the simultaneous rotation of the two first locking handles and the two second locking handles. This enables the door to be opened quickly and the escape rate to be accelerated. When the rotating frame is released, the sliding plate and the sliding frame are automatically reset under the action of the spring force, which is convenient for the next use. In addition, the U-shaped groove ensures that the first locking handle and the second locking handle do not rotate when the sliding frame and the sliding plate are reset, preventing the locking handle from obstructing the closing of the door and making it easy to close the door directly.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 As shown, this utility model provides the following technical solution:

[0028] A sealed hatch structure for a fully enclosed lifeboat includes a door frame 1 and a door panel 2. A door hinge 3 connects the door frame 1 and the door panel 2. A limit frame 11 is slidably connected to the inner side of the door panel 2. Two first lock handles 4 and two second lock handles 5 are rotatably connected to the door panel 2. Each of the two first lock handles 4 and the two second lock handles 5 includes a pivot that rotatably passes through the door panel 2 and two handles fixed at both ends of the pivot. Limit rods 10 are fixedly installed on the four handles located on the inner side of the door panel 2. The limit frame 11 has grooves that slidably engage with the multiple limit rods 10 respectively.

[0029] Two first lock handles 4 are symmetrically distributed at the top and bottom ends of the door panel 2, and two second lock handles 5 are vertically distributed at the end of the door panel 2 away from the door hinge 3. Lock handles 12 are fixedly installed on the pivots of the two first lock handles 4 and the two second lock handles 5. Multiple slots 7 are provided in the door frame 1 to slide and engage with the multiple lock handles 12 respectively. The multiple slots 7 are all quarter-circular structures. The lock handles 12 on the first lock handles 4 are collinear with the corresponding handles, and the lock handles 12 on the second lock handles 5 are perpendicular to the corresponding handles.

[0030] Based on the above publicly available structure, when conducting emergency drills and training for lifeboats:

[0031] First, the crew members turn the first lock handle 4 and the second lock handle 5 to disengage the lock handle 12 on the pivot from the slot 7. Then, they pull the handle located on the outside of the door panel 2 to rotate the door panel. The door frame 1 and the door panel 2 are hinged together by the door hinge 3, causing the door panel 2 to open to one side. The crew members pass through the door frame 1 into the lifeboat. Then, they pull the handle on the inside of the door panel 2 to rotate the door panel 2 closer to the door frame 1, thus closing the door panel 2. Then, they turn the first lock handle 4 and the second lock handle 5 to rotate the lock handle 12 on the pivot back into the slot 7, thus completing the closure of the hatch door.

[0032] Then slide the limiting bracket 11 on one side of the door panel 2, so that the grooves on the limiting bracket 11 abut against the limiting rods 10 on the corresponding handles (e.g., Figure 2 As shown, based on the quarter-circle structure of the slot 7, one side of the lock handle 12 abuts against the side wall of the slot 7, thereby limiting the first lock handle 4 and the second lock handle 5, preventing the lifeboat from shaking and causing the first lock handle 4 and the second lock handle 5 to rotate, thus ensuring the lifeboat's sealing.

[0033] Regarding the fixing of the limiting bracket 11, the following structure is preferably provided:

[0034] Two first guide rods 9 are fixedly installed on one side of the limit frame 11 and are slidably connected to the door panel 2. A top plate 8 is fixedly installed at one end of the two first guide rods 9. A second guide rod 18 is fixedly installed on the door panel 2. A slider 27 is slidably connected to the outside of the second guide rod 18. A first connecting rod 19 is rotatably connected between the slider 27 and the top plate 8.

[0035] A handle 17 is rotatably connected to the slider 27, and a buckle 16 is rotatably connected to the handle 17 at an eccentric position. A hook 15 that cooperates with the buckle 16 is fixedly installed on the door panel 2.

[0036] As can be seen from the above, when the moving limit frame 11 approaches the limit rod 10, the two first guide rods 9 slide on one side of the door panel 2, causing the top plate 8 to move away from the second guide rod 18, and causing one end of the first connecting rod 19 to move away from the second guide rod 18, thereby causing the other end of the first connecting rod 19 to drive the slider 27 to rise along the second guide rod 18. Preferably, when the limit frame 11 abuts against the limit rod 10, the slider 27 moves to the top of the second guide rod 18. At this time, the buckle 16 is rotated and sleeved on the outside of the hook 15. Then, the handle 17 is rotated, causing the end of the buckle 16 to rotate, thereby causing the buckle 16 to sleeve and abut against the hook 15 (as shown in the image). Figure 3 As shown), the slider 27 is fixed, and then the limiting frame 11 is fixed by the first connecting rod 19, the top plate 8 and the first guide rod 9, so that the limiting frame 11 continuously presses against the limiting rod 10.

[0037] In addition, to enable quick opening of the compartment door from the outside, the following structure is preferred:

[0038] A fixing plate is fixed on the rotating shaft of each of the two first locking handles 4 and the two second locking handles 5. A slide rod 23 is fixedly installed on each of the four fixing plates. Two slide plates 24 are symmetrically slidably connected inside the door panel 2. Each slide plate 24 has a U-shaped groove that slides with the slide rod 23. A slide bracket 21 is fixedly connected between the two slide plates 24. The slide bracket 21 is slidably connected to the door panel 2.

[0039] Both slide plates 24 are provided with slide grooves 26, and two fixing rods 25 are fixedly provided on the door panel 2. The two fixing rods 25 are slidably engaged in the two slide grooves 26 respectively.

[0040] A rotating frame 6 is rotatably connected to the door panel 2, and a second connecting rod 20 is rotatably connected between the rotating frame 6 and one end of the slide 21.

[0041] Multiple springs 22 are fixedly connected between the slide 21 and the door panel 2.

[0042] As can be seen from the above, in order to achieve rapid opening of the door, the rotating frame 6 is moved by pulling on the outside of the door panel 2, causing the rotating frame 6 to rotate along the axis at the other end. The rotating frame 6 drives one end of the second connecting rod 20 away from the slide 21, causing the other end of the second connecting rod 20 to drive the slide 21 to slide inside the door panel 2. At the same time, the end of the slide 21 compresses the spring 22, such as... Figure 5 As shown, the movement of the slide 21 drives the two slide plates 24 to move to the right. The two fixed rods 25 on the door panel 2 slide in the slide grooves 26 on the two slide plates 24, which serves as a guide and prevents the slide plates 24 from rotating inside the door panel 2. One side of the U-shaped groove on the slide plate 24 abuts against the slide rod 23, causing the slide rod 23 to move to the right. This causes the fixed rod 25 to rotate around the pivot. The four U-shaped grooves on the two slide plates 24 cause the two first lock handles 4 and the two second lock handles 5 to rotate simultaneously, causing the four lock handles 12 to disengage from the slots 7 at the same time, thereby realizing the rapid opening of the compartment door.

[0043] After the door is opened, one end of the rotating frame 6 is released. Under the elastic force of the spring 22, the slide 21 drives the slide plate 24 to move to the left. The slide 21 then causes the rotating frame 6 to automatically retract through the second connecting rod 20 for easy use next time. At the same time, when the slide plate 24 moves to the left, the U-shaped groove separates from the slide rod 23. The slide rod 23 will not rotate within the range of the U-shaped groove, so that the four locking handles 12 on the two first locking handles 4 and the two second locking handles 5 will not extend out of the door panel 2, making it easy to close the door panel directly and reducing operation time. After the door panel 2 is closed, the first locking handles 4 and the second locking handles 5 are rotated respectively to make the locking handles 12 extend into the slots 7 to close the door.

[0044] Preferably, a sealing strip 13 is fixedly installed on the door panel 2, and a U-shaped sealing groove 14 for wrapping the sealing strip 13 is fixedly installed on the door frame 1. Therefore, when the door panel 2 is rotated to close, the sealing strip 13 on the door panel 2 gradually extends into the U-shaped sealing groove 14 on the door frame 1, so that the U-shaped sealing groove 14 wraps the sealing strip 13. The overlap between the U-shaped sealing groove 14 and the sealing strip 13 is significant, which improves the sealing effect.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
