[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0017] Please refer to Figs. 1 to 3This utility model provides a technical solution: a steering axle tie rod fixing anti-loosening clamp, including a steering tie rod 1, a steering clamp 2 externally fitted at the connection of two steering tie rods 1, the steering clamp 2 serving to connect the two steering tie rods 1, a hexagonal head bolt 3 externally fitted on the steering clamp 2, a hexagonal head nut 7 externally fitted at the bottom of the hexagonal head bolt 3, the cooperation of the hexagonal head bolt 3 and the hexagonal head nut 7 to fix the steering clamp 2 during use, a flat washer 5 externally fitted on the hexagonal head bolt 3, a spring washer 6 externally fitted on the hexagonal head bolt 3, the cooperation of the spring washer 6 and the flat washer 5 to provide anti-slip function, and a limit structure is provided on the outside of the steering clamp 2.
[0018] The top surface of the flat washer 5 fits against the bottom surface of the steering clamp 2, and the spring washer 6 is located below the flat washer 5 and above the hexagonal head nut 7.
[0019] The limiting structure includes an anti-loosening limiting block 4, which is welded to the top and bottom of the steering clamp 2. The anti-loosening limiting block 4 is located behind the hexagonal head bolt 3 and the hexagonal head nut 7 and fits against the hexagonal head bolt 3 and the hexagonal head nut 7. A small distance is left between the front side of the anti-loosening limiting block 4 and the rear side of the hexagonal head bolt 3 or the hexagonal head nut 7, which serves to prevent the hexagonal head bolt 3 and the hexagonal head nut 7 from rotating.
[0020] The limiting structure includes an anti-loosening limiting sleeve 8, which is fitted onto the outside of the steering clamp 2. The anti-loosening limiting sleeve 8 and the steering clamp 2 are welded together.
