Description

Technical Field

[0001] The utility model relates to the technical field of rubber fenders, in particular to a slidable rubber fender. Background Art

[0002] The rubber fender technology is a technology widely used in water area facilities such as ports and docks, aiming to protect ships and dock structures from collision damage. This technology uses rubber fenders to absorb and disperse the impact force from ships or other objects, reducing the risk of structural damage.

[0003] After retrieval, Chinese Patent Publication No.: CN211893573U discloses a gangway-type rubber fender, including a frame. Triangular sponge layers are glued to the front and rear sides of the inner wall of the frame. A number of stepped steps are welded from bottom to top at the bottom of the frame, and anti-slip pads are glued to the upper surfaces of the steps. Through the setting of the anti-slip pads and anti-slip patterns, by gluing the anti-slip pads to the upper ends of the steps and increasing the friction force through the anti-slip patterns, it is avoided that the soles of passengers slip, effectively avoiding the smooth surface of the gangway steps causing the soles of the human body to slip, which is relatively practical and suitable for wide promotion and use.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: a slidable rubber fender, including a chopping board 1, a protective plate 2 is slidably connected to the front end of the chopping board 1, and baffle components are fixedly connected to both the upper and lower ends of the inner wall of the protective plate 2. The baffle components here are used to prevent seawater from entering the inside of the protective plate 2, thereby causing corrosion to it and affecting the service life of this fender. The baffle components include a top plate 3, the outside of the top plate 3 is fixedly connected to the inner wall of the protective plate 2, and a top block 4 is fixedly connected to the top of the top baffle component. The baffle components here play a supporting role for the top block 4.

[0034] Refer to Figure 2 - Figure 3 , the bottom end of the top block 4 is slidably connected to the top end of the chopping board 1, a protective ring 5 is slidably connected to the top end of the top block 4, a handle 6 is fixedly connected to the top end of the protective ring 5. The handle 6 here is used to adjust the left and right movement of this device. A insertion post 7 is fixedly connected to one side of the handle 6, and the outer bottom end of the insertion post 7 is slidably connected to the top end of the top block 4. Many holes matching the insertion post 7 are opened at the top end of the top block 4 here, which is suitable for more precise position adjustment. A first spring 8 is arranged inside the protective ring 5.

[0035] Refer to Figure 3 , a rotating post 9 is slidably connected to the inner wall of the top block 4. The protective ring 5 here plays a role in protecting the first spring 8 from seawater corrosion. One end of the first spring 8 is fixedly connected to one side of the inner wall of the protective ring 5, and the other end of the first spring 8 is fixedly connected to the top end of the rotating post 9. The protective ring 5 and the rotating post 9 here play a role in supporting and fixing the first spring 8. A gear 10 is fixedly connected to the outer top end of the rotating post 9, and the bottom end of the gear 10 is rotatably connected to the top end of the top top plate 3. The rotating post 9 can drive the gear 10 to rotate when rotating here.

[0036] Refer toFigure 2 , the top front side of the chopping board 1 is fixedly connected with a side bar 11, the front end of the side bar 11 is fixedly connected with a rack 12, the gear 10 is meshed with the rack 12, the gear 10 here can move left and right on the rack 12 when rotating, the inner column 13 is fixedly connected to the inside of the guard plate 2, the rear end of the inner column 13 is slidably connected to the front end of the chopping board 1, and the bottom end of the guard plate 2 is fixedly connected with a bottom block 14, the bottom block 14 here mainly plays a role of limiting, so that the guard plate 2 is kept straight when moving and will not deviate.

[0037] Reference Figure 2 and Figure 4 , the outer bottom end of the rotating column 9 is rotatably connected to the inner wall of the bottom block 14, and the outer side of the inner column 13 is fixedly connected with a plurality of protective components, which are used to offset the impact force caused to the fender when the ship docks. The protective components include an inner plate 15, the inner side wall of the inner plate 15 is fixedly connected to the outer side of the inner column 13, and the outer side wall of the inner plate 15 is fixedly connected with a rotating shaft 16. The inner plate 15 here provides a stable support for the rotating shaft 16, and the inner wall of the rotating shaft 16 is rotatably connected with a double connecting rod 17.

[0038] Reference Figure 4 - Figure 5 , the inner wall of the rotating shaft 16 is rotatably connected with an inner rod 18, the outer part of the inner rod 18 is slidably connected to the inner wall of the double connecting rod 17, and the other ends of the double connecting rod 17 and the inner rod 18 are fixedly connected with a support block 19. When the double connecting rod 17 and the inner rod 18 expand to both sides, they will also drive the support block 19 to move together. The outer wall of the support block 19 is fixedly connected with an outer column 20, and a spring 21 is arranged inside the outer column 20. The spring 21 here is used to reduce the impact from the outside;

[0039] Reference Figure 4 - Figure 5 , the inner wall of the outer column 20 is slidably connected with a sliding column 22, and the inner wall of the sliding column 22 is fixedly connected to a limiting block 23. The limiting block 23 here is mainly used to limit the sliding range of the sliding column 22 to prevent it from leaving the inner wall range of the outer column 20. The outer part of the limiting block 23 is slidably connected to the inner wall of the outer column 20, one end of the spring 21 is fixedly connected to one side of the inner wall of the outer column 20, and the other end of the spring 21 is fixedly connected to one side of the limiting block 23. The outer column 20 and the limiting block 23 here provide stable support for the spring 21, so that it maintains stability during operation and extension;

[0040] Reference Figure 4 - Figure 5, the other end of the sliding column 22 is rotatably connected to a slider 24. The outer sides of the two sliders 24 away from the inner plate 15 are slidably connected to an outer plate 25. Here, when an external force acts, it will drive the slider 24 to slide on the inner side wall of the outer plate 25, thereby spreading the direction of the external force, so as to achieve the purpose of weakening the effect of the force. The inner side wall of the outer plate 25 is slidably connected to a connecting rod 26, and the inner side wall of the connecting rod 26 is rotatably connected to one side of the inner plate 15. Here, the connecting rod 26 can also contract when the slider 24 expands to both sides, achieving the purpose of further absorbing the force, and can protect the life of the ship and the shore to the greatest extent.

[0041] Working principle: When this rubber fender helps a ship dock and needs to adjust its left and right positions, the handle 6 can be pulled first. At this time, the handle 6 will drive the plug post 7 to disengage from the engagement with the top block 4. At this time, the handle 6 can be rotated. Because the handle 6 is slidably connected to the first spring 8 here and the middle thin column plays a limiting role, it will drive the first spring 8 to rotate together, and at the same time drive the rotating column 9 below it to rotate, and then drive the gear 10 to rotate and move on the rack 12 engaged with it. Here, the side bar 11 plays a role of supporting and fixing the rack 12, so as to achieve the purpose of adjusting the left and right distances. After adjusting the left and right distances and then releasing the hand, because of the existence of the first spring 8, the plug post 7 is made to re-engage with the top block 4 to prevent dislocation. Here, the protective circle 5 protects the first spring 8 from being eroded by seawater and rainwater and at the same time drives the rotating column 9 to rotate, and the top plate 3 here plays a role of providing support and fixing for the gear 10.

[0042] When the ship hits the surface of the fender 2 during docking, it will first absorb part of the force, and then transfer the remaining force to the outer plate 25. At this time, the outer plate 25 will further transfer the force to the connecting rod 26, causing it to bend. At this time, the slider 24 will slide to both sides, thereby spreading the direction of the pressure, and the second spring 21 inside the outer column 20 will also start to contract, and at the same time drive the sliding column 22 to contract, reducing the effect of the force to the greatest extent. Here, the limit block 23 plays a limiting role. At the same time, the inner rod 18 and the double connecting rod 17 will also expand to both sides under the rotation of the rotating shaft 16, so as to reduce the force received by the inner column body 13, thereby protecting the ship and the chopping board 1 at the same time.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
