Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically to a corrosion-resistant, detachable, and quick-release structure for ship railings. Background Technology

[0002] Ship railings are important safety protection components on ship decks, used to ensure the personal safety of crew members when working on deck. Because ships are in the marine environment for a long time, seawater, moisture and salt spray can have a strong corrosive effect on railings, causing traditional railings to be prone to rust and reduced structural strength, requiring frequent maintenance or replacement.

[0003] Meanwhile, traditional ship railings are mostly fixed by welding or ordinary bolts: although welded connections are structurally stable, they cannot be disassembled. When the railing is partially damaged or the components below the deck need to be repaired, the railing must be cut, which is inefficient and damages the overall structure of the railing. Although ordinary bolt connections can be disassembled, the bolts are easily corroded by the marine environment and can become stuck. Disassembly requires a variety of tools, which is cumbersome. Repeated disassembly can also cause wear on the bolt holes, affecting the stability of the connection.

[0004] Therefore, there is an urgent need for a ship railing structure that combines excellent corrosion resistance with convenient disassembly to solve the problems of rapid corrosion and inconvenient disassembly and assembly in existing technologies. Utility Model Content
