The clamping plate can be moved on the side plate of the ship by a pulley, and the side plate of the ship can be squeezed by an extrusion plate to fix the device on the side plate of the ship. When the first roller is subjected to impact force, the rotating arm will be driven to rotate around the first connecting rod through the U-shaped connecting piece. At this time, the rotating arm will be subjected to the resistance of the shock absorber to obtain the effect of shock absorption and buffering. However, the ship side impact resistant and shock absorbing device in the prior art cannot ensure that the device is installed in the best position when installed on different hulls, thereby reducing the impact resistance effect.

[0004] Therefore, it is urgent to solve the above problems. Utility Model Content

The number of the sinking plates 4 is set to two, and the two sinking plates 4 are arranged axially symmetrically about the vertical center line of the support plate 1. The top of the sinking plate 4 is hinged with an adapter block 20, and the top of the adapter block 20 is fixedly installed with a limited sliding rod 5, and the limited sliding rod 5 is sleeved with an L-shaped mounting frame 6 that is slidably connected, and the L-shaped mounting frame 6 can slide up and down along the limited sliding rod 5. The inside of the L-shaped mounting frame 6 is slidably connected with a sliding block 7, and a sliding groove 21 is provided on the L-shaped mounting frame 6, and the sliding block 7 can move back and forth along the sliding groove 21, and the sliding block 7 is provided with a first step surface 701 that can move back and forth along the sliding groove, and the sliding groove 21 is provided with a second step surface 2101 that contacts the first step surface and is used to support the sliding block. The L-shaped mounting frame 6 is internally slidably connected with a fixed tooth block 8, the inner side of the slide groove 21 is provided with a rack 22, the inner cavity of the sliding block 7 is provided with a fixed tooth block 8, the fixed tooth block 8 is adapted to the rack 22, the inner cavity of the sliding block 7 is provided with a transmission block 19, the transmission block 19 is in contact with the inclined surface of the fixed tooth block 8, the transmission block 19 is used to push the fixed tooth block to move in the direction of the rack, the transmission block 19 is provided with two symmetrically arranged first inclined surfaces, the fixed tooth block 8 is provided with a second inclined surface corresponding to the first inclined surface, and one transmission block 19 pushes the fixed tooth block 8 symmetrically arranged on the left and right to mesh with the corresponding rack 22.

A fixing piece is fixedly installed at the bottom of the sliding block 7, and the fixing piece is connected to the sliding block 7. The fixing piece is used to connect the hull railing. The fixing piece includes a first fixing piece 2 and a second fixing piece 10. The first fixing piece 2 is fixedly installed at the bottom of the sliding block 7. A fastening bolt 9 is inserted into the inside of the first fixing piece 2. The second fixing piece 10 is sleeved on the outside of the fastening bolt 9 and tightened with a fastening nut 11. The first fixing clamp 2 has a first clamping surface that is compatible with the railing, and the second fixing clamp 10 has a second clamping surface that is compatible with the railing.

[0022] During installation, multiple fastening nuts 11 are removed from the outside of the fastening bolts 9 to separate the second fixing member 10, the first fixing member 2 is placed on the top of the railing, and the second fixing member 10 is reset to clamp the railing, and multiple fastening nuts 11 are reset and tightened, and the first fixing member 2 on the other side is fixed to the second fixing member 10. At this time, the L-shaped mounting frame 6 can be pushed and pulled to slide on the outside of the sliding block 7, so that the support plate 1 is extended or retracted accordingly until the support plate 1 is in a vertical state, so as to adapt to different railings and enable the support plate 1 to contact the outside of the hull, and the transmission block 19 is lowered by rotating the handle 18, so that the fixed tooth blocks 8 on both sides are pushed outward and in contact with the L-shaped The racks inside the mounting frame 6 are engaged with each other to complete the fixation, and when the hull collides, the impact force can directly act on the outside of the hull, avoiding the phenomenon that the gap is large and the impact resistance is reduced.

At the same time, the object will contact the rotating column 17. Since multiple limiting frames 15 are installed on one side of the rubber impact-resistant airbag 14, multiple rotating columns 17 will contact the collision object respectively. The rotating column 17 will contact the collision object and rotate to a certain extent, thereby avoiding severe friction with the collision object, thereby reducing the probability of damage to the anti-impact device.
