[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-5As shown, the utility model is provided with a main mounting plate 1 and a secondary mounting plate 2, and there is a certain distance between the two mounting plates. The main mounting plate 1 and the secondary mounting plate 2 are respectively installed with a main hinge support 3 and a secondary hinge support 4 on the upper and lower sides of the main mounting plate 1 and the secondary mounting plate 2 close to each other. Support columns 5 are installed on the upper and lower sides of the front sides of the main mounting plate 1 and the secondary mounting plate 2. Reinforcement columns 6 are welded on both sides of the support columns 5. One end of the reinforcement column 6 is welded to the front side of the mounting plate to provide additional reinforcement and support for the support columns 5. A baffle 7 and a baffle ring 8 are arranged between the main hinge support 3 and the secondary hinge support 4. A pull rod 9 is installed on the end of the baffle 7 close to the baffle ring 8, and there are springs between the baffle 7 and the baffle ring 8. 10. The spring 10 is sleeved on the outside of the pull rod 9, and the retaining ring 8 is sleeved on the outside of the pull rod 9. Two arc-shaped connecting plates 19 are connected to the edge of the retaining ring 8 close to the baffle 7. A circular mounting plate 18 is welded to the other end of the connecting plate 19 connected to the retaining ring 8. A similar circular mounting plate 18 is also installed on the other end of the pull rod 9 connected to the baffle 7. The sides of the two mounting plates 18 that are away from each other are respectively connected to the main hinge support 3 and the secondary hinge support 4. When the main mounting plate 1 and the secondary mounting plate 2 are away from each other, the baffle 7 and the retaining ring 8 will approach each other, compressing the spring 10 between the baffle 7 and the retaining ring 8 to form a limiting structure 11.

[0020] The front ends of the support columns 5 on the front side of the main mounting plate 1 are connected to a main connecting rod 12, and the front ends of the support columns 5 installed on the front side of the auxiliary mounting plate 2 are hinged with a secondary connecting rod 13. The upper main connecting rod 12 and the upper secondary connecting rod 13 are connected together at one end away from the support column 5, and the lower main connecting rod 12 and the secondary connecting rod 13 are also connected in the same way. There is a connecting column 14 between the main connecting rod 12 and the secondary connecting rod 13, and the upper and lower ends of the connecting column 14 are respectively hinged to one end of the two groups of connecting rods that are hinged to each other. A triangle is formed by the support column 5, the main connecting rod 12 and the secondary connecting rod 13, but the distance between the main mounting plate 1 and the secondary mounting plate 2 can be adjusted. When the connecting column 14 is squeezed, it will be transmitted to the spring 10 between the two mounting plates through the connecting rod and the supporting column 5, the baffle 7 and the baffle ring 8 are close to each other, the spring 10 is squeezed, and two evenly distributed inner rings 15 are sleeved on the outside of the connecting column 14, and the outside of the inner ring 15 has an outer wheel 16, and the inner ring 15 and the outer wheel 16 are connected together through three evenly distributed shock absorbers 20, one end of the shock absorber 20 is hinged to the outside of the inner ring 15, and the other end of the shock absorber 20 is hinged to the inner wall of the outer wheel 16, the inner ring 15 and the connecting column 14 are rotatably connected, the inner ring 15 and the outer wheel 16 form a buffer structure 17, and do not affect the rotation of the outer wheel 16.

[0021] In the specific implementation of the utility model, the main mounting plate 1 and the auxiliary mounting plate 2 are first installed through the baffle 7, the baffle ring 8, the pull rod 9, the spring 10 and the mounting plate 18 through the hinge support. Multiple main mounting plates 1 and auxiliary mounting plates 2 can be set to be connected in the same way to surround the side, or ensure that the main mounting plate 1 and the auxiliary mounting plate 2 can be installed in a way that can be moved along the side of the ship within a certain range. The connection ensures that the two mounting plates can be separated from each other by squeezing the spring 10 to disperse a certain impact force and provide a buffer. When the side is hit, the outer wheel 16 receives the impact and moves inward along the axial direction of the impact. The two sets of connected main connecting rods 12 and auxiliary connecting rods 13 that were originally protruding are recessed inward, but the triangle has stability, so the distance that can be moved between the two mounting plates becomes the only variable. The distance between the two mounting plates begins to increase, the distance between the baffle 7 and the baffle ring 8 becomes smaller, the spring 10 is compressed, and at the same time, when the outer wheel 16 receives the impact, it needs to be transmitted to the inner ring 15, and the shock absorber 20 will absorb part of the impact force and then transmit it to the connecting rod.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
