AI Technical Summary
Traditional marine ladders cannot be flexibly adjusted to adapt to different ship heights and operating scenarios, and are not stable enough when the ship is rocking, affecting the safety and work efficiency of the commander.
A self-locking folding ladder was designed, which adopts an adjustable main frame and folding adjustment components, including a mounting part, a step part and a support part. The width and height of the ladder can be adjusted through a self-locking mechanism and an adjustment rod, ensuring a stable connection and upright position on different ships.
It achieves a stable connection of the ladder under different shipboard heights and operating scenarios, improving safety and stability, reducing swaying, and enhancing the operational efficiency and safety of the commander.

Abstract
Claims
1. A self-locking folding marine gangway comprising a main frame and a folding adjustment assembly (4), characterized in that: The main frame includes a mounting part (1), a pedal part (2), and a support part (3). The mounting part (1) is an adjustable structure, including an L-shaped mounting (11) and an adjusting arm (12). The pedal part (2) includes a bracket (21) connected to the mounting part (1) and a pedal (23). An adjusting linkage (22) is provided between the bracket (21) and the pedal (23). The support part (3) includes a support frame (31) located at the front end of the pedal (23) and a support arm located within the support frame (31). The support rod (32) for height adjustment; the folding adjustment assembly (4) includes a first connecting plate (41) and a second connecting plate (44), an adjustment rod (42) is connected between the first connecting plate (41) and the second connecting plate (44), the adjustment rod (42) is connected to the first connecting plate (41) through a first pin and to the second connecting plate (44) through a second pin, and the second connecting plate (44) is provided with a self-locking mechanism (43) to realize the switching between the fixed working state and the folding state of the hanging ladder.
2. The self-locking folding marine gangway according to claim 1, characterized in that: The folding adjustment assembly (4) is disposed between the bracket (21) and the pedal (23) and / or between the pedal (23) and the support frame (31).
3. The self-locking folding marine gangway according to claim 1, characterized in that: The straight arm section of the L-shaped mount (11) is provided with a long groove (111), and the front end of the adjusting arm (12) is slidably set in the long groove (111) by bolts and nuts to adjust the mount width.
4. The self-locking folding marine gangway according to claim 1, characterized in that: The self-locking mechanism (43) includes an adjustment groove (442) provided on the second connecting plate (44) and a pressure plate (432) elastically provided by a torsion spring (431). When the hanging ladder is in the open working state, the second pin abuts against the end of the pressure plate (432) to achieve locking. Pressing down the pressure plate (432) will release the lock and allow the second pin to slide in the adjustment groove (442).
5. The self-locking folding marine gangway according to claim 1, characterized in that: The support frame (31) and support rod (32) are respectively provided with several adjustment holes, and the height of the support part (3) can be adjusted by connecting with a fixing pin.
6. The self-locking folding marine gangway according to claim 1, characterized in that: The second connecting plate (44) is provided with a groove (441), and when the ladder is folded, the first pin is accommodated in the groove (441).
7. The self-locking folding marine gangway according to claim 1, characterized in that: The adjusting link (22) includes a first link and a second link, which are hinged together.
