Description

Technical Field

[0001] The utility model relates to the technical field of fenders, and more specifically to a combined rubber fender. Background Art

[0002] Inflatable rubber fenders are a popular replacement product for ship fenders internationally today. They use compressed air as a buffer medium, allowing the ship to have a softer collision avoidance effect when berthing. Inflatable rubber fenders are a popular replacement product for ship fenders internationally today. They use compressed air as a buffer medium, allowing the ship to have a softer collision avoidance effect when berthing.

[0003] The existing publication number is CN215514053U, and the patent name is a patent document of a large combined inflatable rubber fender, which discloses that the protective tire will play a protective role on the inflatable fender body, avoiding direct contact between the tire and the inflatable fender body;

[0004] However, in actual use, because the ship will not only squeeze the fender horizontally, but also move horizontally to a certain extent, the fender body will move horizontally due to friction, causing the retractable component to be easily twisted and deformed by the horizontal shear force and lose its retractable ability. In view of this, we propose a combined rubber fender. Utility Model Content

The mounting ring 7 is mounted on the outside of the main body and can rotate around the main body. A swivel sleeve is installed on the outer side of the mounting ring. When the ship contacts the main body and moves horizontally to the left and right, the swivel sleeve can rotate so that the side wall of the swivel sleeve shaft is in rolling contact with the outer wall of the main body. At this time, the hull can be prevented from wearing the outer wall of the main body, thereby ensuring the stability of the main body. The swivel sleeve adopts a flexible structure and can also be deformed to assist the main body in deforming to buffer the impact in the front and rear directions of the ship, thereby further improving the stability of the main body.

[0017] Through the setting of pull ropes, pull ropes are installed between adjacent mounting rings. The pull ropes can limit the mounting rings and roughly evenly disperse the mounting rings to avoid excessive mounting rings piling up in smaller positions of the main body. The sleeve rings are located between the rotating sleeves to separate the rotating sleeves and ensure even dispersion of the rotating sleeves during long-term use, thereby ensuring that the mounting rings and the rotating sleeves stably protect the entire outer surface of the main body.
