Technical Field

[0001] The utility model relates to the technical field of ship anti-collision fenders, and more specifically, to an anti-collision rubber fender with a buffer column. Background Art

[0002] Rubber fender is a kind of protective equipment used in places such as ships, docks and docks. In actual applications, rubber fenders are mostly installed at docks. When a ship is docked at a dock, due to the continuous waves in the water, the ship will be driven to collide with the dock. In order to avoid damage to the dock under long-term impact, rubber fenders are set to buffer the impact force to protect the dock.

[0003] At present, most of the rubber fenders are made of rubber and installed on the dock. Although the rubber fender is used for shielding, the ship will not directly hit the dock, so as to protect the dock.

[0004] Although the above method can protect the dock, the current rubber fender is made of rubber, but its hardness is relatively hard. When a ship collides with the rubber fender, although the rubber fender can absorb part of the impact force, the force of absorbing the impact force is limited. When the impact force of the ship is large, it will still affect the dock, thereby affecting the use time of the dock.

[0005] Therefore, it is urgent to design an anti-collision rubber fender with a buffer column to solve the above-mentioned technical problems. Utility Model Content
