[0027] Reference Figure 1 and Figure 3 A plurality of through holes 10 are provided on both sides of the first ladder body 1 for installing and moving other components. A baffle 11 is slidably connected to the inner wall of the through hole 10. A spring 2 12 is fixedly connected to the adjacent side of the two baffles 11 for providing a buffering effect and reducing the impact of external impact. A sliding column 13 is slidably connected to the inner wall of the distant side of the two through holes 10. A protective plate 14 is fixedly connected to the top of the sliding column 13. The distant side of the two baffles 11 and the adjacent side of the two sliding columns 13 and the adjacent side of the two springs 2 12 are fixedly connected to the inner wall of the adjacent side of the through hole 10. The outer side of the protective plate 14 is slidably connected to the inner wall of the slide groove 15.

[0028] Working principle: When the staff installs the handle 8 of the rubber gangway ladder, the cylindrical block 6 is pulled out, which in turn drives the sliding rod 4 to move outward, and then drives the movable plate 3 to move outward, and at the same time compresses the spring 15, thereby driving the diamond block 7 to move outward. At this time, the two handles 8 are inserted into the interior of the first ladder body 1. When the two handles 8 are fully in contact, the cylindrical block 6 is released. At this time, the movable plate 3 will move downward due to the pressure generated by the compression of the spring 15, thereby moving the diamond block 7 downward and finally engaging with the two handles 8, thereby realizing the rapid installation of the gangway ladder handle 8, ensuring that the gangway ladder is firmly and reliably connected to the ship and the land, improving the efficiency and safety of the landing operation, and reducing the waiting time and the difficulty of operation;

[0029] When the rubber gangway is hit by a collision or the impact of sea water, the rubber gangway will be squeezed and move to both sides. At this time, the first ladder body 1 moves to both sides to compress the spring 2 12, and the protection plate 14 slides through the slide groove 15. The pressure generated by the compression of the spring 2 12 can slow down the movement of the first ladder body 1, thereby reducing the impact force on the ship structure when the ship collides with the dock or other ships, which helps to reduce damage to the ship, extend the service life of the ship, reduce maintenance costs, and improve safety.
