Description

Technical Field

[0001] This utility model relates to the technical field of ship accessories and marine equipment, specifically a three-way adjustable hinge device for a marine outdoor door that features a simple structure, good sealing performance, high stability, and strong safety performance. Background Technology

[0002] As is well known, the safety and reliability of ships, as waterborne transportation tools, are of paramount importance. Marine exterior doors, as a crucial component of ships, not only function to isolate compartments and protect crew and equipment, but also need to maintain their airtightness, stability, and reliability under adverse weather and sea conditions. Therefore, the requirements for marine exterior doors and their connecting devices are becoming increasingly stringent.

[0003] Currently, marine exterior doors typically employ traditional fixed connections between the door leaf and frame. While this meets the requirements for marine exterior doors to some extent, it still has shortcomings in certain aspects. For example, traditional connection methods may not be able to withstand hull deformation or the effects of wind and waves, leading to door loosening or damage. Furthermore, after a period of use, the door frame and leaf may deform due to gravity and structural deformation, resulting in excessive gaps between them. Since traditional connection methods do not allow for adjustment of the door's position and angle, addressing these issues presents certain difficulties. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a three-way adjustable hinge device for marine outdoor doors that has a simple structure, good sealing performance, high stability, and strong safety performance.
