Description

Technical Field

[0001] The utility model relates to the technical field of fenders, in particular to a ship fender with the function of alleviating impact force. Background Art

[0002] Fenders, also known as ship guardrails, are elastic buffer devices used on the edge of docks or ships. They are made of wood or rubber. They are mainly used to mitigate the impact force between the ship and the dock or between the ship and the dock during docking or mooring, reducing or eliminating damage to the ship or dock.

[0003] The utility model with the publication number CN213535055U discloses a rubber fender for anti-collision protection of ships, including a rubber fender body, a buffering protrusion fixedly connected to the top of the rubber fender body, a shell fixedly connected to the bottom of the inner cavity of the rubber fender body, a buffer shell fixedly connected to the bottom of the inner cavity of the shell, and an air spring fixedly connected to the bottom of the inner cavity of the buffer shell. The utility model achieves the advantage of good anti-collision protection effect by arranging the rubber fender body, the buffering protrusion, the shell, the buffer shell, the air spring, the buffer rod, the fixed block, the pull rod, the connecting block, the support rod, the mounting plate, the sliding rod, the sliding sleeve, the buffer spring, the compression spring, the slide groove and the slider to cooperate with each other, and solves the problem that the existing rubber fender has poor anti-collision protection effect, and when people use the rubber fender, it is easy to cause the ship to collide with the mooring dock due to the poor buffering compressive strength, causing damage to the ship and inconvenience for people to use.

[0004] Fenders are prone to wear and damage due to long-term friction and collision with the hull. However, in the prior art, fenders are not easy to replace individually and need to be dismantled and replaced as a whole, resulting in large losses. In addition, the deformation of the fender is limited, which limits the buffering effect. The prior art reduces the deformation of the fender, and the curved outer wall of the fender is squeezed between the hull and the buffer mechanism, which easily leads to rupture at this location. The overall structural design of the fender cannot be effectively utilized to achieve the buffering effect. Therefore, a ship fender with impact reduction function is needed to meet the demand.

[0012] Preferably, through holes are provided on both ends of the rotating rod.

[0013] The beneficial effects of the utility model are:

[0014] The utility model uses the rotatability of the rotating rod. When one end of the rotating rod is located in the notch, the rotating rod and the sliding rod are coaxial, so that the D-shaped fender can be smoothly placed on the plug block. The elastic force of the second spring pulls the rotating rod so that the sliding rod and the sliding sheet extend toward the top of the plug block.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A ship fender with impact reduction function comprises a mounting plate 1, a box body 2 is arranged on the mounting plate 1, a sliding frame 3 is slidably installed in the box body 2, a connecting plate 4 is arranged on the sliding frame 3, a plurality of first springs 5 ​​are arranged between the connecting plate 4 and the mounting plate 1, a plurality of plug blocks 6 are arranged on the connecting plate 4, a same D-type fender 7 is movably installed on the plurality of plug blocks 6, a second spring 8 is installed in the plug block 6, a sliding sheet 9 is arranged on the bottom end of the second spring 8, the sliding sheet 9 is slidably installed in the plug block 6, a sliding rod 10 is arranged on the sliding sheet 9, a notch 11 is opened on the sliding rod 10, a rotating rod 12 is rotatably installed in the notch 11, and the rotating rod 12 is located inside the D-type fender 7 and contacts the inner wall of the D-type fender 7.

[0024] Through the rotatability of the rotating rod 12, when one end of the rotating rod 12 is located in the notch 11, the rotating rod 12 is coaxial with the sliding rod 10, so that the D-type fender 7 can be smoothly placed on the plug block 6. Through the elastic force of the second spring 8, the rotating rod 12 is pulled so that the sliding rod 10 and the sliding sheet 9 extend toward the top of the plug block 6. Through the rotation of the rotating rod 12, the rotating rod 12 horizontally limits the bottom end of the D-type fender 7. Through the resilience of the second spring 8 after compression, the connection between the D-type fender 7 and the connecting plate 4 is guaranteed. Compared with the prior art, the installation and replacement of the D-type fender 7 is convenient, while avoiding the dismantling of the entire device and reducing the loss. In addition, the structural design of the D-type fender 7 is fully utilized to achieve the buffering effect. Through the cooperation between the mounting plate 1, the box body 2, the sliding frame 3, the connecting plate 4 and the first spring 5, the D-type fender 7 is provided with a buffer, the impact force is reduced, and the buffering effect of the entire device is further improved to prevent the D-type fender 7 from being damaged when the deformation amount reaches the maximum value.

[0025] Specifically, in this embodiment, a limit frame 13 is set on the bottom end of the sliding frame 3, the outer wall size of the limit frame 13 is larger than the outer wall size of the sliding frame 3, and the limit frame 13 is slidably installed in the box body 2. The limit frame 13 prevents the sliding frame 3 from popping out when it is subjected to the elastic force of the first spring 5 from the box body 2.

[0026] Specifically, in the present embodiment, a sealing ring 14 is embedded in the outer wall of the limit frame 13, and the sealing ring 14 contacts the inner wall of the box body 2. The sealing ring 14 improves the sealing between the sliding frame 3 and the box body 2, so that when the sliding frame 3 slides in the box body 2, the internal air is compressed, thereby forming a damping effect, slowing down the movement speed of the sliding frame 3.

[0027] Specifically, in this embodiment, the connection portion between the rotating rod 12 and the notch 11 is located at the center of the rotating rod 12 to ensure that both ends of the rotating rod 12 are balanced, so that the rotating rod 12 can stably press and fix the D-type fender 7.

[0028] Specifically, in this embodiment, a plug hole 15 is provided on the bottom end of the D-shaped fender 7, the plug hole 15 is adapted to the plug block 6, and the inner diameter of the plug hole 15 is smaller than the length of the rotating rod 12, so that when the rotating rod 12 is horizontal, both ends are pressed on the D-shaped fender 7.

The cross hole 16 has a small gap to prevent seawater from entering the D-type fender 7 and causing corrosion to the installation mechanism. The elasticity of the D-type fender 7 itself allows the cross hole 16 to expand, making it convenient to insert a tool to operate the rotating rod 12.

[0030] Specifically, in this embodiment, through holes 17 are provided at both ends of the rotating rod 12 , and a hook can be hung in the through hole 17 to apply a pulling force and a force to drive the rotating rod 12 to rotate.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall make equivalent replacements or changes, which shall be covered by the protection scope of the utility model.
