Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] The utility model provides an anti-loosening U-shaped nail, which solves the technical problem that the U-shaped nail in the prior art is simple in structure and has no anti-loosening structure, and mainly relies on the friction between itself and the lawn to achieve fixation, so that it is easy to loosen after fixation, resulting in poor stability of the lawn;
[0026] See also Figure 1-Figure 5 The utility model provides a technical solution: an anti-loosening U-shaped nail, comprising a U-shaped nail body 1, the U-shaped nail body 1 is composed of a limiting spiral fixing mechanism 2 and a body 3.
[0027] The limiting spiral fixing mechanism 2 includes a rotating rod 21 and a rotating seat 22. A spiral rotating piece 211 is welded on the outer surface of the rotating rod 21 near the bottom end. The main body 3 is composed of a cross bar structure 31, a first vertical rod structure 32 and a second vertical rod structure 33. The first vertical rod structure 32 and the second vertical rod structure 33 are respectively provided with a first embedded inclined end surface 34 and a second embedded inclined end surface 35 on the side away from the cross bar structure 31. The first embedded inclined end surface 34 and the second embedded inclined end surface 35 are respectively fixedly installed with a first cog array 36 and a second cog array 37. The first cog array 36 and the second cog array 37 are composed of a plurality of groups of cog main bodies 38 equidistantly distributed from top to bottom. When installing, the bottom end of the main body 3 can be first aligned with the positioning point and the introduction part, and then the rotating rod 21 can be passed through the U-shaped bayonet 311 at the cross bar structure 31 near the top, and rotated. The rotating seat 22 is moved, and the spiral rotating piece 211 is spirally introduced into the interior of the lawn until the rotating seat 22 is located on the top surface of the main body 3. At this time, the main body 3 is downwardly moved under the downward force of the limiting spiral fixing mechanism 2 until it is embedded into a proper depth. The U-shaped nail main body 1 composed of the limiting spiral fixing mechanism 2 and the main body 3 can be driven by the rotating rod 21 to spirally insert the spiral rotating piece 211 into the interior of the lawn, which greatly increases the adhesion with the lawn. At the same time, the first embedded inclined end face 34, the second embedded inclined end face 35 and the first cog array 36 and the second cog array 37 thereon can limit the main body 3 introduced into the interior of the lawn to increase the resistance. In summary, the overall U-shaped nail structure has a good anti-loosening effect by increasing the adhesion with the lawn and increasing the limiting resistance inside the lawn, thereby ensuring the stability of the turf.

The conical end 381, the first inclined surface 382 and the horizontal surface 384 respectively provided on the bottom end, outer side and top surface of the cog body 38 can reduce the resistance when the cog body 38 is embedded, increase the limiting resistance inside the lawn, and make it less likely to loosen, thereby greatly improving the overall installation stability.

[0031] In addition, in this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The bottom surface of the rotating seat 22 is fixedly connected to the top of the rotating rod 21 through the limiting clamping seat 222, and the diameter of the rotating seat 22 is larger than the diameter of the limiting clamping seat 222; a U-shaped clamping seat 311 adapted to the limiting clamping seat 222 is provided through the center of the crossbar structure 31 near the edge, and the U-shaped clamping seat 311 is combined with the limiting clamping seat 222 to facilitate the positioning of the limiting screw fixing mechanism 2 during installation, and to facilitate the disassembly and assembly with the limiting screw fixing mechanism 2;
[0032] The working process of the utility model is as follows: during installation, the bottom end of the main body 3 can be first aligned with the positioning point and the guide part, and then the rotating rod 21 can be passed through the inside of the U-shaped bayonet 311 at the cross bar structure 31 near the top, and the rotating seat 22 can be rotated. At this time, the spiral rotating piece 211 can be spirally guided downward into the inside of the lawn until the rotating seat 22 is located on the top surface of the main body 3, and the limiting seat 222 is located inside the U-shaped bayonet 311. At the same time, the limiting seat 222 rotates in the U-shaped bayonet 311.
