[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Embodiment one

[0023] Please refer to Figures 1-5The utility model provides a wear -resisting rubber fender, including fender body 1, one side of fender body 1 is detachably connected with wear -resisting spare 2, wear -resisting spare 2 can prevent with fender body 1 and is separated through locking assembly, and locking assembly includes connecting rod 3, screw rod 4 and sleeve 5, and one side of wear -resisting spare 2 equidistance installs three groups of connecting rod 3, and each group of connecting rod 3 can penetrate fender body 1, and the one end of connecting rod 3 inserted fender body 1 is all penetrated with screw rod 4, and the both ends of screw rod 4 are connected with sleeve 5, and the one end of sleeve 5 away from screw rod 4 is integrally formed with knob 6, and knob 6 is hexagonal structure spare.

[0024] Connecting rod 3 installed on one side of wear -resisting spare 2 is inserted into the prearranged hole in fender body 1, screw rod 4 is passed through the inner chamber of fender body 1 and penetrates the hole in connecting rod 3, and sleeve 5 is threadedly connected on the both ends of screw rod 4, sleeve 5 is fastened by rotating knob 6, so that wear -resisting spare 2 is firmly connected with fender body 1, since knob 6 is hexagonal structure spare, therefore can use spanner etc. Tool to conveniently rotate sleeve 5, realize quick and accurate installation and disassembly, compared with prior art, when the ship is berthed or collides with the wharf, wear -resisting spare 2 will first bear the impact force, since it has higher hardness and wear resistance, therefore can effectively protect fender body 1 from damage, if wear -resisting spare 2 is worn or damaged during use, wear -resisting spare 2 can be conveniently replaced by disassembling locking assembly, without replacing the whole fender body 1, thereby reduce maintenance cost and improve resource utilization.

[0025] Specifically, a buffer is arranged between the fender body 1 and the wear-resistant part 2, the buffer is a first spring 7, the first spring 7 is provided with three groups and is sleeved outside the three groups of connecting rods 3, and the inner cavity of the fender body 1 is provided with three groups of shock-absorbing parts corresponding to the three groups of connecting rods 3, the shock-absorbing part comprises a damping telescopic rod 8 and a second spring 9, the damping telescopic rod 8 is sleeved with the second spring 9 outside, and the damping telescopic rod 8 is installed on one side of the inner cavity of the fender body 1.

[0026] When the wear-resistant part 2 is impacted by the ship, it will first bear this part of the impact force, since the wear-resistant part 2 is connected with the shock-absorbing part inside the fender body 1 through the connecting rod 3, so the impact force will be transmitted along the connecting rod 3 to the shock-absorbing part and the fender body 1. Before the impact force is transmitted to the fender body 1, the first spring 7 sleeved outside the connecting rod 3 will first act, the first spring 7 uses its elastic property to absorb and disperse part of the impact force, thereby slowing down the direct action of the impact force on the fender body 1. Through the synergistic effect of the three groups of first springs 7, the impact force can be more evenly dispersed, and the buffering performance of the fender can be improved. When the impact force continues to be transmitted to the inner cavity of the fender body 1, the shock-absorbing part begins to work. The damping telescopic rod 8 uses its damping property to absorb and consume part of the impact force. When the impact force acts on the damping telescopic rod 8, it will deform in extension and contraction, thereby absorbing part of the energy. At the same time, the second spring 9 sleeved outside the damping telescopic rod 8 also starts to work. It uses its elastic deformation to further absorb and disperse the impact force. Through the synergistic effect of the damping telescopic rod 8 and the second spring 9, the impact force can be more effectively absorbed and dispersed, and the direct influence of the impact force on the fender body 1 and the ship can be reduced.

[0027] Among them, the two sides of the fender body 1 are provided with fastening assemblies, and the fastening assembly comprises a bolt 10 and a baffle 11. The bolt 10 can penetrate the baffle 11 and the fender body 1. The fender body 1 is provided with a clamping groove 12 corresponding to the baffle 11.

[0028] Firstly, the baffle 11 is aligned with the clamping groove 12 on the fender body 1 to ensure that the baffle 11 can be smoothly clamped into the clamping groove 12. Then, the bolt 10 penetrates the baffle 11 and the fender body 1 from one side of the fender body 1 until the end of the bolt 10 is exposed. Next, according to the specific situation, the bolt 10 can be threadedly connected with a reserved part or connected with a nut. If it is threadedly connected with the reserved part, the bolt 10 is directly screwed into the reserved part. If it is connected with a nut, a nut needs to be installed at the end of the bolt 10 and tightened,

[0029] After the baffle 11 is clamped into the clamping groove 12, it can effectively prevent the bolt 10 from loosening or falling off when subjected to external force. After the bolt 10 is threadedly connected with the reserved part or connected with the nut, the stability of the connection can be further increased. Threaded connection has self-locking property and can prevent the bolt 10 from loosening to a certain extent. When connected with a nut, sufficient pre-tightening force can be generated by tightening the nut to make the connection more compact. The design of the fastening assembly enables the fender body 1 to be firmly fixed at the required position and can adapt to different installation environments and conditions. The bolt 10 and the baffle 11 are usually made of high-strength materials and have excellent wear resistance and corrosion resistance, so they can be used for a long time without failure in harsh environments.

[0030] Working principle: align the baffle 11 with the clamping groove 12 on the fender body 1, ensure that the baffle 11 can be smoothly clamped into the clamping groove 12, then, the bolt 10 penetrates the baffle 11 and the fender body 1 from one side of the fender body 1 until the end of the bolt 10 is exposed, next, according to the specific circumstances, the bolt 10 can be threadedly connected with the reserved part, or connected with the nut, if threadedly connected with the reserved part, directly screw the bolt 10 into the reserved part, if connected with the nut, the nut needs to be installed at the end of the bolt 10 and tightened, the connecting rod 3 installed on one side of the wear-resistant part 2 is inserted into the pre-designed hole in the fender body 1, the screw rod 4 is passed through the inner cavity of the fender body 1 and penetrates the hole in the connecting rod 3, the sleeve 5 is threadedly connected at both ends of the screw rod 4, the sleeve 5 is fastened by rotating the knob 6, the wear-resistant part 2 is firmly connected with the fender body 1, if the wear-resistant part 2 is worn or damaged during use, the wear-resistant part 2 can be conveniently replaced by disassembling the locking assembly, without replacing the entire fender body 1, thereby reducing the maintenance cost and improving the resource utilization.
