Description

Technical Field

[0001] This utility model relates to the field of ship cabin mechanical equipment, and in particular to a hanging cabin door fixing structure. Background Technology

[0002] The interior space of a ship is limited, especially between upper and lower decks, engine room, cargo hold or pipeline passage. If it is not possible to install hatches on the side walls or sides, hatches can only be opened on the ground (or deck). Ground hatches can connect upper and lower compartments in the vertical direction, facilitating the entry and exit of crew or goods.

[0003] Due to limited interior space, some ground-level hatches are located beneath stairs. These hatches, situated on the ground beneath the stairs in confined spaces, present significant inconvenience in practical use and fail to meet the requirements for convenience, safety, and reliability in complex spatial environments. Specifically, in actual use, hatches automatically close under gravity after opening upwards. If crew members need to carry items or tools with both hands or pass through quickly after opening the hatch, the inability to keep it open increases the operational burden. Furthermore, in emergencies, automatically closing hatches may delay evacuation or hinder rescue efforts, posing a safety hazard to the crew. Utility Model Content

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0026] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] As shown in the figure, this utility model includes a door frame 5, a hatch 2, a winch 4, and a locking assembly 3. One side of the hatch 2 is hinged to the side of the door frame 5 via a hinge 6. The side of the hatch 2 away from the hinge 6 is connected to the winch 4. The winch 4 can be electric or manual and can drive the hatch 2 to open and close via a steel cable. The locking assembly 3 includes a fixed lug 7 and a locking mechanism. The fixed lug 7 is fixedly connected to the hatch 2, and the locking mechanism is located outside the hatch 2. It can connect with the fixed lug 7 to lock the hatch 2 in the open state and can be unlocked from the fixed lug 7 before the hatch 2 is closed. In this example, the preferred application scenario is that the hatch 2 and the door frame 5 are located on the ground / horizontal surface / deck below the stairs 1, and the locking mechanism is installed below the stairs 1.

[0028] The locking mechanism includes a fixed box, through which the fixed lug 7 is connected to the locking mechanism. The locking mechanism includes a spring pin 8 located inside the fixed box, positioning plates on both sides of the spring pin 8, and an unlocking moving plate 11. The fixed lug 7 has a hanging lug groove, and the spring pin 8 includes a hanging shaft 9. When the hatch 2 is locked in the open state, the hanging shaft 9 is located in the hanging lug groove of the fixed lug 7. Before the hatch 2 is closed, the hanging shaft 9 can be moved out of the hanging lug groove of the fixed lug 7.

[0029] Specifically, the spring pin 8 also includes a side plate fixedly connected to the fixed box, a fixed block 12 fixedly connected to the side plate, a guide rod 13 passing through the fixed block 12, a movable block 15 fixedly connected to the end of the guide rod 13, and a locking spring 14 connecting the fixed block 12 and the movable block 15. The locking spring 14 is sleeved on the guide rod 13. The middle part of the hanging shaft 9 passes through the movable block 15. The positioning plate, the unlocking moving plate 11, and the side plate are respectively provided with waist-shaped holes. The waist-shaped holes are strip-shaped structures, allowing the hanging shaft 9 to move back and forth within the waist-shaped holes. When the hatch 2 is opened, the fixed lug 7 on the hatch 2 pushes open the hanging shaft 9 and compresses the locking spring 14. When the hanging shaft 9 enters the lug groove, the locking spring 14 returns to its natural state. The hanging shaft 9 is pushed by the locking spring 14 and the movable block 15 to lock the fixed lug 7, thereby fixing the hatch 2.

[0030] In addition, the locking mechanism also includes an unlocking rotating rod 10. The end of the unlocking rotating rod 10 is provided with an external thread and is threadedly connected to the positioning plate. In this example, a nut is fixedly connected to one side of the positioning plate to make the end of the unlocking rotating rod 10 threadedly connected to the positioning plate. The unlocking rotating rod 10 passes through the spring pin 8 and the unlocking moving plate 11. The unlocking rotating rod 10 can rotate relative to the unlocking moving plate 11 and can also drive the unlocking moving plate 11 to move the hanging shaft 9 out of the hanging ear groove. Specifically, the surface of the unlocking rotating rod 10 is provided with a first annular groove 16, and the unlocking moving plate 11 has a circular hole. The first annular groove 16 is located at the circular hole of the unlocking moving plate 11, so that the unlocking rotating rod 10 can rotate freely and can drive the unlocking moving plate 11 to reciprocate through the grooved boss. The surface of the hanging shaft 9 is provided with a second annular groove 17. The first annular groove 16 is located at the waist-shaped hole of the unlocking moving plate 11, so that during the reciprocating movement of the unlocking moving plate 11, the hanging shaft 9 is moved out of the hanging ear groove through the grooved boss of the hanging shaft 9. When the hatch 2 is unlocked and lowered, the unlocking rotating rod 10 is rotated. The unlocking rotating rod 10 drives the unlocking moving plate 11 to move. Since the hanging shaft 9 is connected to the moving plate, the hanging shaft 9 is moved out of the hanging ear groove of the fixed lifting ear 7, thereby unlocking the fixed lifting ear 7.

[0031] In summary, this utility model utilizes a winch as a power source and uses steel cables for traction, avoiding the inconvenience of using the hatch due to the narrow space under the stairs. After the hatch is opened, the fixed lifting lugs and locking mechanism work together to stably lock the hatch in the open state, eliminating the risk of the hatch closing unexpectedly due to gravity. This provides an absolutely safe and unobstructed passage for crew members to pass through, move goods, or perform maintenance tasks.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
