In the description of the present utility model, the meaning of "several" is two or more unless otherwise clearly and specifically defined.

[0027] Please refer to Figures 1 - 5 as shown, a technical solution provided by the present utility model:

[0028] A fastening device for ship and vehicle transportation with an anti-loosening function, comprising a lower clamp 1. A ratchet shaft 2 is rotatably connected between the lower clamps 1. Both ends of the ratchet shaft 2 are fixedly connected with gears 3. The outer sides of the two gears 3 are rotatably connected with the same upper clamp 4. Symmetrically arranged sliding grooves one 5 are formed in the inner side of the upper clamp 4. The same sliding plate one 6 is slidably connected between the two sliding grooves one 5. A sliding component is arranged in the sliding plate one 6. Symmetrically arranged sliding grooves two 7 are formed in the inner side of the lower clamp 1. The same sliding plate two 8 is slidably connected between the two sliding grooves two 7. A rectangular plate 9 is arranged above the sliding plate two 8. A sliding groove three 10 is formed in the rectangular plate 9. A limiting component is arranged in the sliding groove three 10. An L-shaped sliding plate 11 is slidably connected in the sliding groove three 10. An elastic component is arranged in the L-shaped sliding plate 11. The other end of the L-shaped sliding plate 11 is fixedly connected with a tension spring 12. The other end of the tension spring 12 is fixedly connected with an L-shaped rod 13, and the other end of the L-shaped rod 13 is fixedly connected with one side of the rectangular plate 9.

[0029] Furthermore, the sliding component includes a fourth chute 14 which is formed in the first slide plate 6. Magnetic attraction surfaces 15 are provided at both ends of the fourth chute 14. A third slide plate 16 is slidably connected in the fourth chute 14, and both ends of the third slide plate 16 are attracted to the magnetic attraction surfaces 15 respectively, so that the third slide plate 16 enters the fourth chute 14, releasing the clamping connection between the third slide plate 16 and the gear 3, and preventing the gear 3 from rotating when the upper clamp 4 rotates, which may cause the rope on the gear 3 to become loose.

[0030] Furthermore, the limiting component includes a limiting plate 17 which is fixedly connected in the third chute 10, and the third chute 10 is located above the L-shaped slide plate 11, preventing the L-shaped slide plate 11 from wobbling when sliding and limiting the sliding of the L-shaped slide plate 11.

[0031] Furthermore, the elastic component includes a sliding column 18 which is slidably connected in the L-shaped slide plate 11. A spring 19 is fixedly connected to the bottom end of the sliding column 18, and the other end of the spring 19 is fixedly connected to a bottom plate 20. The other end of the bottom plate 20 is fixedly connected to the other side of the rectangular plate 9. Before use, the position of the L-shaped slide plate 11 is fixed, so that the hook-shaped block on the third slide plate 16 can be clamped with the hook-shaped part at one end of the L-shaped slide plate 11, facilitating the subsequent operations.

[0032] Furthermore, a hook-shaped block is fixedly connected to one side of the third slide plate 16, and the hook-shaped block is adapted to the other end of the L-shaped slide plate 11. When the L-shaped slide plate 11 is subjected to the pulling force of the tension spring 12, it can drive the third slide plate 16 into the fourth chute 14, preventing the bottom end of the third slide plate 16 from being clamped with the gear 3, which may cause the gear 3 to rotate when the upper clamp 4 rotates.

[0033] Furthermore, the top end of the sliding column 18 is in an arc structure, enabling it to complete the corresponding movement better when being squeezed.

[0034] Furthermore, one side of the second slide plate 8 abuts against the gear 3, preventing the gear 3 from rotating and avoiding the rope on the gear 3 from becoming loose.

[0035] When the fastening device for ship and vehicle transportation with anti-loosening function in this embodiment is in use, when people rotate the upper clamp 4 in the direction of the lower clamp 1, at this time, the first slide plate 6 will rotate in the same direction as the upper clamp 4. After that, the hook-shaped block on the third slide plate 16 will contact the arc of the sliding column 18. Then, when continuing to rotate, the hook-shaped block on the first slide plate 6 will squeeze the sliding column 18 and compress the spring 19 into the L-shaped slide plate 11 until the hook-shaped block on the first slide plate 6 is engaged with the hook-shaped part on the L-shaped slide plate 11. At this time, the upper clamp 4 rotates to the horizontal state, and at the same time, the position of the upper clamp 4 is fixed. Then, the L-shaped slide plate 11 will move in the direction close to the L-shaped rod 13 under the pulling force generated by the tension spring 12. Subsequently, the L-shaped slide plate 11 will drive the third slide plate 16 into the fourth chute 14, releasing the abutting state between the third slide plate 16 and the gear 3, further preventing the gear 3 from rotating when the upper clamp 4 rotates in the direction away from the lower clamp 1, resulting in the loosening of the rope on the gear 3. When the rotation state of the upper clamp 4 is completely ended, at this time, the convex part at the upper clamp 4 will abut against one side of the second slide plate 8, preventing the second slide plate 8 from moving backward and causing the gear 3 to rotate. When the use is over, people rotate the upper clamp 4 in the direction away from the lower clamp 1. At this time, the upper clamp 4 will drive the first slide plate 6 to rotate in the same direction. At the same time, the hook-shaped block on the third slide plate 16 will drive the L-shaped slide plate 11 to move in the direction away from the L-shaped rod 13. At this time, one end of the L-shaped slide plate 11 will contact the arc of the sliding column 18, causing the sliding column 18 to compress the spring 19 and enter the bottom plate 20 until the sliding column 18 is aligned with the circular hole in the L-shaped slide plate 11. At this time, the sliding column 18 will be bounced back into the L-shaped slide plate 11 by the spring 19. At the same time, due to the increase in the angle between the upper clamp 4 and the lower clamp 1, at this time, the hook-shaped block of the third slide plate 16 will be disengaged from the hook-shaped part of the L-shaped slide plate 11, facilitating people to fix the upper clamp 4 next time.
