[0032] Example 1

[0033] A ground nail for convenient rope threading and disassembly comprises a ground nail body 1, a limiting part 3, a rope clamping part 2 and an elastic component 4.

[0034] like Figures 1 to 4 As shown, the ground nail body 1 includes a nail head 11 located at the top of the ground nail body 1, a nail tip 13 located at the end of the ground nail body 1, and a nail body 12 located between the nail head 11 and the nail tip 13. The nail head 11, the nail body 12 and the nail tip 13 are arranged in sequence. The ground nail body 1 can be inserted into the ground through the nail tip 13 to achieve a stable connection with the ground.

[0035] In this embodiment, the rope clamping part 2 is an integrated structure with the nail body 12. One end of the rope clamping part 2 is connected to the side wall of the nail body 1, and a gap is left between the other end of the rope clamping part 2 and the side wall of the nail body 1, and the gap is defined as gap a. A rope clamping groove 5 is provided between the two ends of the rope clamping part 2.

[0036] Furthermore, the rope clamping part 2 is configured as a "U"-shaped plate-like structure, with one end of the "U"-shaped rope clamping part 2 (defined as end b) being connected to the upper end of the nail body 12, and a gap a being left between the other end of the "U"-shaped rope clamping part 2 (defined as end c) and the nail body 12, and the end b and the end c are located on the same side of the nail body 12, and a rope clamping groove 5 is provided between the end b and the end c; wherein the upper and lower ends of the rope clamping groove 5 extend to the top and bottom ends of the rope clamping part 2 respectively, and when the rope body passes through the rope clamping groove 5, the upper and lower ends of the rope body can pass through the top and bottom ends of the rope clamping part 2, thereby being able to conveniently adjust the length of the rope body required to be fixed.

[0037] Furthermore, a cutout 9 is provided at the other end of the rope clamping part 2, and the distance between the cutout 9 and the ground nail body 1 gradually decreases from the nail head 11 to the nail tip 13. Specifically, a cutout 9 is provided at the c end of the rope clamping part 2, and in this embodiment, only the cutout 9 in the shape of an inverted triangle is taken as an example. The inverted triangle-shaped cutout 9 is a structure that is wide at the top and narrow at the bottom, and the distance between the cutout 9 and the nail body 12 gradually decreases from the upper end of the cutout 9 to the lower end of the cutout 9. By providing the cutout 9 in the shape of wide at the top and narrow at the bottom, the operator can conveniently insert the rope body from the upper end of the cutout 9, and at the same time, when the rope body needs to be disassembled, the rope body can also be pulled out from the upper end of the cutout 9 to the lower end.

[0038] The limiting part 3 is arranged at the rope clamping groove 5, one end of the limiting part 3 is connected to the ground nail body 1, the other end of the limiting part 3 abuts against the rope clamping groove 5, and the limiting part 3 closes the gap; the ground nail body 1 is also provided with a limiting groove 6, and the limiting part 3 can be inserted into the limiting groove 6.

[0039] Specifically, one end of the limiting portion 3 (defined as end d) is rotatably connected to the ground nail body 1 through a rotating shaft. When the operator presses the limiting portion 3, the limiting portion 3 can rotate around the rotating shaft, so that the other end of the limiting portion 3 (defined as end e) can rotate to the abutment or snap into the limiting groove 6. In this embodiment, the size of the limiting groove 6 matches the limiting portion 3, and the limiting groove 6 can accommodate the limiting portion 3.

[0040] like Figure 1 As shown, the limiting portion 3 is an arc-shaped plate-like structure, and the limiting portion 3 extends along the nail head 11 of the ground nail body 1 toward the nail tip 13, and a distance (the distance is defined as distance f) is reserved from the connection between the limiting portion 3 and the ground nail body 1 to the rope clamping groove 5, so that the limiting portion 3 and the rope clamping groove 5 are arranged obliquely; by setting the inclination angle, when the rope body is installed, the operator can easily pull the rope body from the reserved distance f to the gap a; when the rope body is disassembled, the operator can also pull and drag the rope body from the reserved distance f to the gap a.

[0041] Furthermore, a protrusion 7 is provided on the limiting portion 3, and the protrusion 7 is arranged at the abutment between the limiting portion 3 and the rope clamping groove 5. When the rope body is located in the rope clamping groove 5, the protrusion 7 fits the rope body and is arranged in the direction of the nail tip 13 of the ground nail body 1. The protrusion 7 can further clamp the rope body. By setting the protrusion 7 in the direction of the nail tip 13, the rope body can be prevented from moving in the direction of the nail head 11. At the same time, when the rope body needs to be disassembled, the operator can pull the rope body in the direction of the nail tip 13, and the rope body can escape from the gap a along the protrusion 7. Since the barb structure 8 at the protrusion 7 is arranged in the direction of the nail tip 13, the rope body is not easy to move from the bottom of the limiting portion 3 to the nail head 11. The rope body above the limiting portion 3 is dragged to move in the direction of the nail tip 13, and the rope body can slide along the barb structure 8, so that the rope body can be easily escaped.

[0042] Furthermore, the protrusion 7 is provided with a barb structure 8, which can further automatically clamp the rope body, thereby preventing the rope body from sliding.

[0043] One end of the elastic component 4 is connected to the ground nail body 1, and the other end of the elastic component 4 is connected to the limiting part 3. When the rope body passes through the gap, the rope body presses the limiting part 3 to the limiting groove 6, and compresses the elastic component 4; after the rope body passes through the gap, the rope body is located in the rope clamping groove 5, and the elastic component 4 can automatically push the limiting part 3 to clamp the rope body at the abutment.

[0044] Specifically, the elastic component 4 is a torsion spring, and the torsion spring includes a torsion spring body 41, a first clamping end 42 and a second clamping end 43. The limiting part 3 is provided with a first clamping groove 31 for clamping the first clamping end 42, and the first clamping end 42 is connected to the first clamping groove 31; the ground nail body 1 is provided with a second clamping groove 14 for clamping the second clamping end 43, and the second clamping end 43 is connected to the second clamping groove 14. Among them, a certain angle is preset between the first clamping end 42 and the second clamping end 43. When the limiting part 3 rotates, the limiting part 3 squeezes the torsion spring and can apply torque to the torsion spring. The rotational force of the torsion spring can act in reverse on the limiting part 3. When the rope body is clamped into the rope clamping groove 5, under the action of the rotational force of the torsion spring, the limiting part 3 can pop out from the limiting groove 6 and automatically clamp the rope body, so that the limiting part 3 presses the rope body to the abutment.

[0045] In this embodiment, the ground nail body 1 is provided with a rope hole 16, which is used to bind and fix the rope body. When the limiting part 3 presses the rope body to the abutment, part of the rope body is located outside the rope clamping groove 5, and the operator can bind the part of the rope body to the rope hole 16, thereby further fixing the rope body.

[0046] In this embodiment, a striking portion 15 is provided at the top of the ground nail body 1. The striking portion 15 is a circular structure. The operator uses a hammer to strike the striking portion to fix the ground nail body 1 on the ground.

[0047] The method for convenient rope threading and removal using the above-mentioned ground nail for convenient rope threading and removal includes the following steps:

[0048] (1) Rope installation steps;

[0049] The operator pulls the rope from the cutout 9 to the gap a, the rope will be cut obliquely to press the upper end of the limiter 3, the lower end of the limiter 3 will be inserted into the limiter groove 6, and the rope will be inserted into the rope clamping groove 5 from the gap a;

[0050] When the rope body is located in the rope clamping groove 5, the operator releases the limiting part 3. At this time, the reaction force of the torsion spring can push the limiting part 3 to pop out from the limiting groove 6 and the lower end of the popped-out limiting part 3 can move to the abutment point, and then the barb structure 8 of the limiting part 3 can automatically clamp the rope body and press the rope body to the rope clamping groove 5.

[0051] (2) Rope disassembly steps;

[0052] When the rope body needs to be disassembled, the operator drags the rope body located above the limiting portion 3, and the rope body sequentially escapes from the cutout 9 and the gap a.
