Description

Technical Field

[0001] This utility model relates to the technical field of fender fixing devices, specifically a marine fender fixing device. Background Technology

[0002] A fender, also known as a ship's guardrail, is an elastic cushioning device used on the edge of a dock or ship. Made of wood or rubber, it primarily reduces the impact force between a ship and the dock or other vessels during berthing or mooring, minimizing or eliminating damage to the ship or dock. For example, utility model patent CN215884013U discloses a ship fender fixing device, including a deck extension plate, a fender reinforcement, a first fixing mechanism, and a second fixing mechanism. The deck extension plate is fixed to the upper surface of the main deck and extends beyond it. The fender reinforcement protrudes from the ship's side plate, and the deck extension plate and the fender reinforcement form a receiving portion to accommodate the fender. The two ends of the first fixing mechanism are connected to the deck extension plate and the fender reinforcement, respectively, to wrap around and fix the fender within the receiving portion. The second fixing mechanism passes through the deck extension plate, the fender, and the fender reinforcement in sequence and then secures itself. The first and second fixing mechanisms are spaced apart to reduce fender wear during jacking operations while ensuring the stability of the fender installed on the ship's side. Furthermore, if one of the fixed mechanisms is damaged and there are no spare parts, the other fixed structure can be used to temporarily maintain the working state, saving the procurement cycle for maintenance and enabling the ship to be repaired in a timely manner.

[0003] Traditional fenders are typically fixed directly to the edge of the hull deck, making them prone to damage from wear and tear or collisions. Furthermore, this traditional method makes fender replacement inconvenient. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a marine fender fixing device, which solves the problem that traditional fenders are generally directly fixed to the edge of the hull deck, and are easily damaged after wear or collision. However, the traditional fixing method is not convenient for replacing the fender.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine fender fixing device, including a hull deck, an mounting base welded to the edge of the hull deck, a fender slidably connected inside the mounting base, a spring fixedly connected to the inner wall of the mounting base, a baffle fixedly connected to the end of the spring, and the baffle slidably connected inside the mounting base, the baffle abutting against the fender, a plurality of fixing pins slidably connected to the top of the mounting base, and the fixing pins penetrating the mounting base, one end of the fixing pin slidably connected to the fender, the other end of the fixing pin fixedly connected to a connecting piece, a locking button fixedly connected to the upper end of the connecting piece, and a spring two sleeved on the outer side of the fixing pin.

[0006] Preferably, one end of the second spring is fixedly connected to the connecting piece, and the other end of the second spring is fixedly connected to the mounting base. By using the second spring, the reaction force can be applied to the fixing pin through the connecting piece.

[0007] Preferably, a linkage bar is fixedly connected to the top of each fixing pin, and the linkage bar is made of stainless steel. The linkage bar allows all fixing pins to be pulled upwards simultaneously.

[0008] Preferably, a hollow shell is fixedly connected to the top of the mounting base. A locking pin is slidably connected inside the hollow shell and penetrates through the hollow shell. One end of the locking pin is inserted into a locking button, and the other end of the locking pin is fixedly connected to a magnetic plate, which attracts the hollow shell. A pull ring is fixedly connected to the magnetic plate, and a retaining ring is fixedly connected to the pin body of the locking pin, which is slidably connected inside the hollow shell. A spring is sleeved on the outside of the pin body of the locking pin. By inserting the locking pin into the locking button, the axial direction of the fixing pin can be limited, thereby ensuring the stability of the fixing pin in limiting the fender.

[0009] Preferably, one end of the third spring is fixedly connected to the retaining ring, and the other end of the third spring is fixedly connected to the inner surface of the hollow shell. By using the third spring, the elastic force can be applied to the locking pin through the retaining ring.

[0010] Preferably, the retaining ring has ball bearings on its side, and the ball bearings are in contact with the inner surface of the hollow shell. The ball bearings reduce the sealing pressure between the retaining ring and the hollow shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model welds a mounting base to the side of the ship's deck, into which the fender can be inserted. A fixing pin with a spring is then installed on the mounting base. The fixing pin is inserted into the fender from above. In this way, the installation and fixing of the fender can be completed simply by controlling the engagement and disengagement of the fixing pin and the fender. This method is more convenient than the previous method of directly fixing the fender to the ship's deck and is also easier to replace later.

[0013] 2. This utility model provides a hollow shell on the mounting base, with a locking pin that is extended and retracted by a spring inside the hollow shell. The locking pin is inserted laterally into the locking button at the top of the fixing pin. In this way, after the fixing pin is inserted into the fender, its axial direction can be restricted, thereby preventing it from detaching from the fender due to vibration and ensuring the stability of the fender installation.

[0022] Please see Figure 1-4A locking button 8 is fixedly connected to the upper end of the connecting piece 6, and a second spring 7 is sleeved on the outer side of the pin body of the fixing pin 5. One end of the second spring 7 is fixedly connected to the connecting piece 6, and the other end of the second spring 7 is fixedly connected to the mounting base 2. The second spring 7 allows the reaction force to be applied to the fixing pin 5 through the connecting piece 6. A linkage bar 9, made of stainless steel, is fixedly connected to the top of the fixing pin 5. The linkage bar 9 allows all fixing pins 5 to be pulled upwards simultaneously.

[0023] Please see Figure 2-3 A hollow shell 10 is fixedly connected to the top of the mounting base 2. A locking pin 11 is slidably connected inside the hollow shell 10 and passes through the hollow shell 10. One end of the locking pin 11 is inserted into the locking button 8, and the other end of the locking pin 11 is fixedly connected to a magnetic piece 12, which is attracted to the hollow shell 10. A pull ring 13 is fixedly connected to the magnetic piece 12. A retaining ring 14 is fixedly connected to the pin body of the locking pin 11 and is slidably connected inside the hollow shell 10. A spring 3 16 is sleeved on the outside of the pin body of the locking pin 11. By inserting the locking pin 11 into the locking button 8, the axial movement of the fixing pin 5 can be limited, thereby ensuring the stability of the fixing pin 5 in limiting the fender 3. One end of the spring 3 16 is fixedly connected to the retaining ring 14, and the other end of the spring 3 16 is fixedly connected to the inner surface of the hollow shell 10. The spring 3 16 allows the elastic force to act on the locking pin 11 through the retaining ring 14. The retaining ring 14 has balls 15 on its side, and the balls 15 are in contact with the inner surface of the hollow shell 10. The balls 15 reduce the sealing between the retaining ring 14 and the hollow shell 10.

[0024] The specific implementation process of this utility model is as follows: In use, firstly, pull the locking pin 11 horizontally through the pull ring 13 to separate the locking pin 11 from the locking button 8. Then, keep the locking pin 11 in its state and pull each fixing pin 5 simultaneously through the linkage bar 9, while stretching the second spring 7. Then, insert the fender 3 into the mounting base 2 and release the linkage bar 9. The fixing pin 5 will reset under the action of the second spring 7 and be inserted into the fender 3 from above. Finally, reinsert the locking pin 11 into the locking button 8 to complete the installation and fixation of the fender 3. The stability after installation is also high.
