DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0025] like Figure 1 and Figure 2 As shown, a self-locking spiral ground pile includes a pile body 20, which is hollow cylindrical, has a conical bottom, and has a threaded outer arc surface. This is an existing technology and will not be described in detail here.

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the locking structure is arranged on the arc surface of the pile body 20 to lock the pile body 20 in the soil. The locking structure includes: a rotating shaft 23, a slider 30, a shifting groove 32, a connecting rod 33 and a flipping rod 34. The rotating shaft 23 is rotatably connected to the cavity of the pile body 20, the slider 30 is threadedly connected to the wall surface of the rotating shaft 23, the shifting groove 32 is opened on the side wall surface of the slider 30, the connecting rod 33 is rotatably connected to the slider 30, the flipping rod 34 is rotatably connected to the side wall surface of the pile body 20, and the end of the flipping rod 34 is also rotatably connected to the connecting rod 33.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the slider 30 is a rectangular block, the side wall surface of the shifting groove 32 of the slider 30 is arc-shaped, the shifting groove 32 is a rectangular notch, a cylinder is fixedly connected in the shifting groove 32, the top of the connecting rod 33 is rotatably connected to the cylinder in the shifting groove 32, and the locking structure also includes a top groove 21, a turning handle 24, a screw groove 31, a soil dividing rod 35, a receiving groove 36 and a giving groove 37. The top groove 21 is opened at the top of the pile body 20, the turning handle 24 is fixedly connected to the top of the rotating shaft 23, the screw groove 31 runs through the top of the slider 30, the soil dividing rod 35 is fixedly connected to the side wall surface of the turning rod 34, the receiving groove 36 is opened at the pile body 2 0 side wall, the giving way groove 37 is opened on the side wall of the pile body 20 above the receiving groove 36, the top groove 21 is a circular groove, the turning handle 24 is a capsule-shaped plate, the turning handle 24 can rotate in the top groove 21, the rotating shaft 23 can pass through the screw groove 31 and be threadedly connected to the wall surface of the slider 30 in the screw groove 31, the bottom of the turning rod 34 is rotatably connected to the wall surface of the pile body 20 at the bottom of the receiving groove 36, the soil dividing rod 35 is a rod with a triangular cross-section, the receiving groove 36 can adapt to the sizes of the turning rod 34 and the soil dividing rod 35, the giving way groove 37 can be connected to the receiving groove 36, and the giving way groove 37 can adapt to the size of the connecting rod 33;

[0028] When in use, the entire pile body 20 is driven into the ground through the threaded nails on its wall surface. After the pile body 20 is nailed into the ground, the turning handle 24 is rotated. The turning handle 24 can drive the rotating shaft 23 to rotate synchronously in the pile body 20 cavity when rotating. The rotating shaft 23 can drive the slider 30 to slide along the wall surface of the rotating shaft 23 through the threaded connection in the screw groove 31 when rotating. The slider 30 can drive the cylinder in the shifting groove 32 to move synchronously when sliding downward. At this time, the top of the connecting rod 33 will move downward, and the bottom of the connecting rod 33 will press the turning rod 34 to one side, and the turning rod 34 can drive the soil dividing rod 35 to rotate sideways with the bottom of the turning rod 34 as the center of the circle. The soil dividing rod 35 and the wall surface of the turning rod 34 will be stuck in the soil, thereby fixing the position of the pile body 20;

[0029] In summary, by setting up a locking structure, the pile body 20 can be locked in the ground. The locking structure fixes the position of the pile body 20 and then rotates the turning rod 34 and the soil dividing rod 35 to the side, so that the pile body 20 and the soil dividing rod 35 form an anchor shape in the ground, thereby preventing the pile body 20 from moving. Therefore, this solution can self-lock the pile body 20 in the ground.

[0030] like Figure 2 and Figure 4 As shown, a limiting structure is provided in the cavity of the pile body 20, and the limiting structure includes a limiting edge 22 and a limiting ring 25. The limiting edge 22 is symmetrically fixedly connected to the cavity wall of the pile body 20, and the limiting ring 25 is symmetrically fixedly connected to the wall surface of the rotating shaft 23. The wall surface of the symmetrical limiting edge 22 can contact the symmetrical flat surface of the slider 30. The limiting ring 25 is annular and is respectively provided at the bottom and the middle section of the rotating shaft 23. The wall surface of the rotating shaft 23 can contact the wall surface of the slider 30.

[0031] In actual use, when the slider 30 moves, the slider 30 will always move symmetrically between the limiting edges 22. After the slider 30 moves to the top of the lower limiting ring 25, the rotating shaft 23 will not be rotated. After the slider 30 moves to the bottom of the upper limiting ring 25, the rotating shaft 23 will not be rotated.

[0032] In summary, by setting a limiting structure, the displacement of the slider 30 can be limited, thereby preventing the slider 30 from being misplaced due to excessive rotation of the shaft 23, which would render the device unusable. Therefore, the limiting structure can improve the stability of the device during use.

[0033] Working principle: The entire pile body 20 is driven into the ground through the threads on its wall. After the pile body 20 is driven into the ground, the handle 24 is rotated. The handle 24 can drive the rotating shaft 23 to rotate synchronously in the cavity of the pile body 20 when it is rotated. The rotating shaft 23 can drive the slider 30 to slide along the wall of the rotating shaft 23 through the threaded connection in the screw groove 31 when it is rotated. The slider 30 can drive the cylinder in the shifting groove 32 to move synchronously when it slides downward. At this time, the top of the connecting rod 33 will move downward, and the bottom of the connecting rod 33 will press the turning rod 34 to one side. The turning rod 34 can drive the soil dividing rod 35 to rotate sideways with the bottom of the turning rod 34 as the center of the circle. The soil dividing rod 35 and the wall surface of the turning rod 34 will be stuck in the soil, thereby fixing the position of the pile body 20.
