[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-3, an embodiment provided by the present utility model: a semi-trailer box body with a side buffer and anti-collision structure, including a moving rod 4. A plurality of groups of moving rods 4 are provided, and the position of the moving rod 4 can be adjusted as needed. The inner wall of the front end of the moving rod 4 is elastically connected with a sliding ring 9 through a first spring 10. The inner wall of the sliding ring 9 is slidably connected to the outer wall of a sliding column 7. The movement of the sliding ring 9 can drive a fixed block 11 to move simultaneously. When the bearing plate 3 is impacted and drives the sliding column 7 and the fixed ring 15 to move backward, the fixed ring 15 squeezes the sliding ring 9 to compress the first spring 10. When the fixed ring 15 is not affected by external force, the first spring 10 ejects the fixed ring 15 and the sliding column 7 forward through the sliding ring 9. One end of the first spring 10 is fixedly connected to the inner wall of the front end of the moving rod 4, and the other end of the first spring 10 is fixedly connected to the outer wall of the rear end of the sliding ring 9. A fixed block 11 is fixedly connected to the outer wall of the left end of the sliding ring 9. The movement of the fixed block 11 can drive a rotating plate 12 to rotate around a cylinder 13, driving a pulley 14 to change its position. The inner wall of the left end of the fixed block 11 is slidably connected with the rotating plate 12. The rotation of the rotating plate 12 can drive the pulley 14 to rotate, making the pulley 14 contact with a friction block 16. The rotating plate 12 is arranged in an L shape and is rotatably connected to the outer wall of the cylinder 13. A through groove is opened in the inner wall of the rear side of the upper end of the rotating plate 12. A pulley 14 is rotatably connected to the inner wall of the front end of the rotating plate 12. The outer wall of the pulley 14 is rough, and contacting with the friction block 16 can slow down the moving speed of the sliding column 7. A cylinder 13 is fixedly connected to the inner wall of the front end of the moving rod 4, providing support for the rotation of the rotating plate 12. A sliding column 7 is slidably connected to the inner wall of the front end of the moving rod 4, providing guidance for the sliding of the bearing plate 3. A bearing plate 3 is fixedly connected to the outer wall of the front end of the sliding column 7, for receiving external impacts. A guiding component is fixedly connected to the outer wall of the sliding column 7. A friction block 16 is fixedly connected to the inner wall of the left end of the sliding column 7. The friction block 16 contacts with the pulley 14, increasing the frictional resistance and slowing down the moving speed of the sliding column 7. An adjusting component is slidably connected to the outer wall of the right end of the moving rod 4, and the outer wall of the rear end of the adjusting component is fixedly connected to a carriage 1.

[0031] Referring to Figure 1 and Figure 2 , the adjusting component includes a fixed column 2, which provides support for the sliding of the moving rod 4. The moving rod 4 can be fixed on the fixed column 2 through an inserting block 6. The outer wall of the rear end of the fixed column 2 is fixedly connected to the inner wall of the rear end of the carriage 1. The inner wall of the front end of the moving rod 4 is elastically connected with the inserting block 6 through a second spring 5. By pressing the inserting block 6 backward, the outer wall of the front end of the inserting block 6 is separated from the inner wall of the front end of the fixed column 2, and then the moving rod 4 can be moved to adjust its position. After that, release the inserting block 6, so that the inserting block 6 is clamped on the inner wall of the front end of the fixed column 2 to fix the position of the moving rod 4. The outer wall of the front end of the inserting block 6 is slidably connected to the inner wall of the front end of the moving rod 4, and the outer wall of the front end of the inserting block 6 penetrates and is slidably connected to the inner wall of the front end of the fixed column 2. One end of the second spring 5 is fixedly connected to the outer wall of the rear end of the inserting block 6, and the other end of the second spring 5 is fixedly connected to the inner wall of the front end of the moving rod 4.

[0032] Refer to Figure 3 , the guiding component includes a fixing ring 15. The fixing ring 15 is arranged to press against the sliding ring 9. The moving speed of the sliding column 7 can be slowed down by the sliding ring 9 and the first spring 10. The inner wall of the fixing ring 15 is fixedly connected to the outer wall of the sliding column 7. A guiding rod 8 is fixedly connected to the outer wall of the rear end of the fixing ring 15. The guiding rod 8 provides guidance for the sliding of the fixing ring 15 and the sliding column 7. There are four guiding rods 8, and the outer wall of the rear side of the guiding rod 8 penetrates and is slidably connected to the inner wall of the front end of the sliding ring 9.

[0033] Working principle: By pressing the insert block 6 backward, the outer wall of the front end of the insert block 6 is separated from the inner wall of the front end of the fixing column 2. After moving the moving rod 4 to the required position, release the insert block 6, so that the insert block 6 is clamped on the inner wall of the front end of the fixing column 2 to fix the position of the moving rod 4. When the bearing plate 3 is impacted, the bearing plate 3 drives the sliding column 7 and the fixing ring 15 to move backward. When the fixing ring 15 presses the sliding ring 9 backward, the sliding ring 9 moves backward to compress the first spring 10. When the sliding ring 9 moves backward, it drives the fixing block 11 to move backward. The fixing block 11 moving backward drives the rotating plate 12 to rotate around the cylinder 13, so that the pulley 14 contacts the friction block 16, slowing down the moving speed of the sliding column 7 and providing buffering for the impact. When the fixing ring 15 drives the sliding ring 9 to continue moving backward, the rotating plate 12 clamps the sliding column 7 through the pulley 14, stopping the sliding column 7 from moving and protecting the inner wall of the carriage 1.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
