Detailed Description

The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.

Referring to fig. 1 and 2, the present embodiment provides a self-adjusting spiral ground pile, which includes a ground pile body 1 and a flange 2; the flange 2 comprises an upper disc body 21 and a lower disc body 22; the top end of the ground pile main body 1 is detachably connected with the upper disc body 21 through a bolt 5. The upper tray body 21 and the lower tray body 22 are both provided with round mounting holes 23; the top end of the ground pile main body 1 is provided with a mounting groove 221, and two sides of a notch of the mounting groove 221 are provided with side grooves 222;

a driving rod is arranged in the mounting groove 221, the driving rod comprises an upper rod 61 and a lower rod 62, an insertion groove 621 for the upper rod 61 to enter is formed in the end portion of the lower rod 62, and a first spring 81 is arranged between the bottom end of the upper rod 61 and the bottom of the insertion groove 621; the top activity of upper boom 61 pierces through in last disk body 21, simultaneously, inlays on the body of rod that upper boom 61 and last disk body 21 contact and is equipped with sealing washer 3 for the rainwater can not get into from gap between them, causes the body of rod surface to rust.

The bottom of the lower rod 62 is provided with a bottom plate 65, and the size of the bottom plate 65 is matched with that of the mounting groove 221; a second spring 82 is arranged between the bottom of the bottom plate 65 and the bottom of the mounting groove 221; the upper rod 61 is fixedly sleeved with a first gear 63.

A second gear 71 is meshed and sleeved outside the first gear 63, a connecting rod 72 is arranged on the second gear 71, and the connecting rod 72 penetrates through the side groove 222 and is fixedly connected with the lower disc body 22; an annular rack 64 is arranged on the rod body of the lower rod 62; the installation groove 221 is also internally provided with a third gear 73, a bevel gear 74, a fourth gear 76 and a transmission rod 75.

With reference to fig. 2 and 3, the third gear 73 includes a flat tooth portion 731 and a tapered tooth portion 732, and the flat tooth portion 731 is coaxially connected to the tapered tooth portion 732; the flat tooth portion 731 is engaged with the annular rack 64, and the conical tooth portion 732 is engaged with the bevel gear 74; the bevel gear 74 is coaxially connected with the transmission rod 75. The upper end of the transmission rod 75 is coaxially connected with a fourth gear 76; the fourth gear 76 is meshed with the first gear 63.

In addition, a limiting rod 77 is disposed on the side wall of the mounting groove 221, and a limiting ring 78 is mounted at the end of the limiting rod 77, in this embodiment, the transverse section of the limiting ring 78 is C-shaped and is made of a spring material. The transmission rod 75 is movably arranged in the limiting ring 78 in a penetrating way; the body of rod 75 is provided with a stop block above and below the stop ring 78.

The working principle is as follows:

therefore, when the fixing object is pressed against the upper tray 21, the key of the bolt 5 enters the mounting holes 23 of the upper tray 21 and the lower tray 22 at the same time; at the same time, the upper rod 61 is pressed to descend, compressing the first spring 81, so that the lower rod 62 also descends. In actual manufacturing, the spring constant of the first spring 81 is larger than that of the second spring 82, so that the upper rod 61 can be smoothly lowered.

As the lower rod 62 descends, the rack 64 pushes the third gear 73 to rotate, the third gear 73 drives the fourth gear 76 to rotate through the transmission rod 75, and the fourth gear 76 drives the first gear 63 to rotate, so that the upper rod 61 rotates. The first gear 63 drives the second gear 71 to rotate, and then the lower tray body 22 rotates by a certain angle through the connecting rod 72, so that the mounting holes 23 on the upper tray body 21 and the lower tray body 22 do not completely overlap, and a certain staggering is formed, specifically referring to fig. 4, so that the bolt body of the bolt 5 is simultaneously extruded by the hole walls of the upper and lower 2 mounting holes 23, and cannot be displaced, and further, the stability of the mounting structure is stronger.
