Description

Technical Field

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

[0002] Rubber fenders are usually used to reduce friction and impact between the hull and the dock or other ships when the ship is moored, and to protect the dock facilities and the ship hull. It is made of rubber with high elasticity, high strength, wear resistance and aging resistance, and can withstand various climatic conditions and marine environment.

[0003] Most of the existing rubber fenders can only rely on the buffering capacity of the rubber fender itself to buffer the collision force generated between the ship and the dock or between the ships when docking or mooring, and no anti-collision buffer structure is further set, resulting in the rubber fender The buffering and shock absorption effect is not superior enough, and it is easy to cause the ship and the dock to be damaged by collision. Based on these problems, Chinese patent CN221273488U discloses a buffer type rubber fender. By setting a main buffer mechanism and an auxiliary buffer mechanism, the rubber fender body can be used to initially buffer the collision force generated when the ship is docked, and then the main buffer mechanism and the auxiliary buffer mechanism can be used to perform secondary buffering on the collision force, effectively reducing the impact force during the mooring process between the ship and the dock, and preventing the ship and the dock from being damaged. By setting an installation mechanism, the rubber fender body can be replaced separately when it is aged or damaged after long-term use, without replacing the entire equipment, saving the use cost, and the replacement process is simple, which is convenient for staff to operate.

[0004] The buffer spring in the auxiliary buffer mechanism on the mounting plate is exposed to the outside. When the buffer spring is corroded by rain or sea water, it will rust, which will not only affect the buffering effect of the buffer mechanism, but also increase the use cost of the fender.

By setting a connecting structure among the first threaded rod 6, the first nut 7 and the first limiting tube 5, the first pad 9 can be fixed on the base plate 1. By setting the first rubber cover 8, the connecting structure between the first threaded rod 6 and the first nut 7 can be covered, thereby achieving dustproof, waterproof and moisture-proof effects, which helps to slow down the rusting speed of the connecting structure between the first threaded rod 6 and the first nut 7.

[0036] The first pad 9 is fixedly connected to a slide plate 10 at the center of the front end, and a slide groove is opened at the front end of the slide plate 10. Side plates 11 are fixedly connected to both sides of the front end of the first pad 9, and sliding rods 12 are fixedly connected to the opposite surfaces of the side plates 11. Slide blocks 13 are slidably connected to both ends of the outer walls of the slide rods 12, and buffer springs 14 are installed on the opposite surfaces of the two groups of slide blocks 13. Rollers 15 are installed at the centers of the rear ends of the slide blocks 13. The movable ends of the rollers 15 are rollingly connected to the inner walls of the slide plate 10, and the rollers 15 can roll in the slide groove inside the slide plate 10, which is beneficial to improving the stability and smoothness of the sliding of the slide blocks 13. The top and bottom of the slide blocks 13 are fixedly connected to a first mounting plate 16, and the front ends of the first mounting plates 16 are fixedly connected to a second threaded rod 17, and one end of the outer wall of the second threaded rod 17 is sleeved with a second mounting plate 18, and the other end of the outer wall of the second threaded rod 17 is threadedly connected with a second nut 19.

[0037] The opposite surface of the second mounting plate 18 is fixedly connected with the first hinge 20, and the movable end of the first hinge 20 is rotatably connected with the connecting plate 21, and the front end of the connecting plate 21 is rotatably connected with the second hinge 22.

By setting a connection structure between the threaded ring 26 and the short axis bolt 27, the arc rubber pad 28 can be fixed on the third mounting plate 25. By setting a simple connection method between the threaded ring 26 and the short axis bolt 27, the disassembly and assembly steps of the arc rubber pad 28 are more convenient and quick. When the arc rubber pad 28 is collided, the movable column 24 at the rear end of the third mounting plate 25 will move together toward the direction of the bottom plate 1. At this time, the connecting plate 21 will gently rotate a certain angle on the rear end surface of the second pad 23. At the same time, the two sets of sliders 13 on the same slide rod 12 will slide in opposite directions, and then the buffer spring 14 will be squeezed. When the buffer spring 14 pops out, it can play a buffering effect.

[0039] A rubber frame 29 is fixedly connected to the outer edge of the front end of the base plate 1, and a shell 30 is sleeved on the outer wall of the rubber frame 29. By setting the shell 30, the buffer spring 14 can be shielded. By setting the rubber frame 29, it is beneficial to improve the sealing of the connection structure between the shell 30 and the base plate 1, thereby preventing external rainwater from falling into the shell 30.

By setting the dustproof ventilation net 31, it is helpful to quickly balance the air pressure inside and outside the shell 30. When the shell 30 is directly sleeved on the outer wall of the rubber frame 29, the dustproof ventilation net 31 will discharge a small amount of gas inside the shell 30. It is worth noting that before rainy and snowy weather arrives, the dustproof ventilation net 31 needs to be covered.

[0040] The third threaded rod 32 is fixedly connected to both sides of the front end of the L-shaped frame 2, and the fourth mounting plate 33 is fixedly connected to the top and bottom rear ends of the shell 30. The second limiting sleeve 34 is penetrated at both ends of the fourth mounting plate 33. The front end of the outer wall of the third threaded rod 32 is threadedly connected to the third nut 35, and the front end of the outer wall of the second limiting sleeve 34 is sleeved with a second rubber cover 36. By setting the connection structure between the third threaded rod 32, the third nut 35 and the second limiting sleeve 34, the shell 30 can be fixed on the base plate 1. By setting the second rubber cover 36, the connection structure between the third threaded rod 32 and the third nut 35 can be covered, thereby achieving dustproof, waterproof and moisture-proof effects, which helps to slow down the rusting speed of the connection structure between the third threaded rod 32 and the third nut 35.
