DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application / this application to clearly and completely describe the technical solutions in the embodiments of this application / this application. Obviously, the described embodiments are only part of the embodiments of this application / this application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the application / this application and its application or use. Embodiment 1

[0020] This embodiment provides a ground anchor to solve the problem of difficulty in recovering the ground anchor in the prior art.

[0021] refer to Figures 1 to 7 The ground anchor provided in this embodiment includes: A stopper 20 for fixing in the anchor foundation 19; It also includes an umbrella pole anchor rib 3 and an umbrella frame rib 9. The umbrella pole anchor rib 3 is used to connect the anchored object. Figure 1 and Figure 2, a pull ring 2 can be arranged on the umbrella pole anchor 3, and the pull ring 2 is connected to the anchored object through the pull wire 1; in addition, the umbrella pole anchor 3 passes through the limiting piece 20 for fixing the umbrella pole anchor 3, and one end of the umbrella pole anchor 3 is connected to the umbrella-shaped frame rib 9, and the umbrella-shaped frame rib 9 is used to prevent the umbrella pole anchor 3 from escaping from the limiting piece 20; when in use, the umbrella pole anchor 3 completes the anchoring effect through two actions cooperating with each other: 1. The limiting piece 20 limits the lateral movement of the umbrella pole anchor 3, and 2. The umbrella pole anchor 3 prevents the umbrella pole anchor 3 from axially escaping from the limiting piece 20; It also includes a sleeve 11. When recovery is required, the umbrella pole anchor 3 is subjected to axial pressure, and the umbrella pole anchor 3 presses the umbrella-shaped frame ribs 9 into the sleeve 11. The umbrella-shaped frame ribs 9 are retracted along the sleeve 11. After the umbrella-shaped frame ribs 9 are retracted, they no longer have a significant resisting effect on the axial withdrawal of the umbrella pole anchor 3. Under the action of external force, the umbrella pole anchor rib 3 can be pulled out from the limiting member 20.

[0022] When in use, the limiting member 20 and the sleeve 11 are arranged at a preset anchor point (such as an opening) of the anchor foundation 19 (such as the ground); a hole is opened on the limiting member 20 for the umbrella pole anchor rib 3 to pass through; the umbrella pole anchor rib 3 passes through the limiting member 20 from the end of the limiting member 20 that is easy to operate (such as the ground side), and is connected to the umbrella-shaped frame rib 9 at the end of the limiting member 20 that is not easy to operate (such as deep inside the ground); the umbrella-shaped frame rib 9 is in an unfolded state, and the umbrella pole anchor rib 3 is connected to the anchored object at the end of the limiting member 20 that is not easy to operate; when it needs to be recovered, the umbrella pole anchor rib 3 is pressed downward toward the end of the limiting member 20 that is not easy to operate, and the umbrella-shaped frame rib 9 is pressed into the sleeve 11, and the umbrella-shaped frame rib 9 is retracted under the action of the sleeve 11; the umbrella pole anchor rib 3 is pulled out from the end of the limiting member 20 that is easy to operate, and the umbrella-shaped frame rib 9 can be pulled out alone for recovery, or it can be pulled out together with the umbrella-shaped frame rib 9 in the retracted state for recovery.

[0023] It is worth noting that there is no order between arranging the limiting member 20 on the anchoring foundation 19 and passing the umbrella pole anchor rib 3 through the limiting member 20. The umbrella-shaped frame rib 9 can be arranged on the umbrella pole anchor rib 3 first, and the limiting member 20 can be arranged on the anchoring foundation 19, so that after the umbrella-shaped frame rib 9 is folded, the umbrella pole anchor rib 3 and the umbrella-shaped frame rib 9 pass through the limiting member 20 together; or, the umbrella pole anchor rib 3 passes through the limiting member 20 and then connects to the umbrella-shaped frame rib 9, and then installs the limiting member 20 with the umbrella pole anchor rib 3 on the anchoring foundation 19; or, the umbrella pole anchor rib 3 with the umbrella-shaped frame rib 9 is placed in the anchor point, and then the limiting member 20 is made around the umbrella pole anchor rib 3.

[0024] As one embodiment, the limiting member 20 can be obtained by injection hardening or a prefabricated member.

[0025] As one of the embodiments, the size of the sleeve 11 can be designed to be smaller than the unfolded size of the umbrella-shaped frame rib 9 so that the umbrella-shaped frame rib 9 can be collapsed after being pressed in. As one of the embodiments, the collapse includes folding or the umbrella-shaped frame rib 9 is fitted with the umbrella pole anchor rib 3. As one of the embodiments, the collapse of the umbrella-shaped frame rib 9 and the pull-out of the umbrella pole anchor rib 3 should include at least two situations: 1. The size of the umbrella-shaped frame rib 9 after collapse is similar to or smaller than the umbrella pole anchor rib 3, so that the umbrella-shaped frame rib 9 can be pulled out from the limiter 20; 2. When the umbrella-shaped frame rib 9 is collapsed but not pulled out, the size of the umbrella-shaped frame rib 9 is still unable to directly pass through the umbrella-shaped frame rib 9, but is in a state of "can be further collapsed". When the umbrella pole anchor rib 3 is subjected to the pull-out force, the limiter 20 can drive the umbrella-shaped frame rib 9 to collapse further until it reaches a size that can pass through the limiter 20.

[0026] In summary, the ground anchor provided in this embodiment utilizes the folded / expanded state of the umbrella-shaped frame rib 9 to control the anchoring and recovery of the umbrella pole anchor rib 3. The recovery of the umbrella pole anchor rib 3 can be achieved simply by pressing down the umbrella pole anchor rib 3. By utilizing the working relationship between the sleeve 11 and the umbrella-shaped frame rib 9, the folding control of the umbrella-shaped frame rib 9 is transferred to the umbrella pole anchor rib 3, which facilitates the implementation of the recovery operation of the umbrella pole anchor rib 3. Embodiment 2

[0027] This embodiment provides a ground anchor. This embodiment is optimized on the basis of the first embodiment to improve the technical effect and refine the technical solution. For the contents not fully described in this embodiment, please refer to the first embodiment.

[0028] refer to Figure 1 , Figure 2 , Figures 4 to 7 The umbrella-shaped frame rib 9 includes a limiting umbrella rod 9.1 rotatably connected to the umbrella rod anchor rib 3. The limiting umbrella rod 9.1 and the umbrella rod anchor rib 3 are also elastically connected through a first elastic member 9.3. The first elastic member 9.3 is used to drive the limiting umbrella rod 9.1 to unfold to prevent the umbrella rod anchor rib 3 from escaping from the limiting member 20.

[0029] As one embodiment, the first elastic member 9.3 may be a spring, and the first elastic member 9.3 is arranged at the armpit of the limit umbrella rod 9.1. If the umbrella rod anchor rib 3 presses the umbrella-shaped frame rib 9, the limit umbrella rod 9.1 is pressed into the sleeve 11, and when the umbrella-shaped frame rib 9 is in the folded state, Figure 1 , Figure 4 and Figure 6 , the angle between the limit umbrella rod 9.1 and the umbrella rod anchor 3 becomes smaller, and the first elastic member 9.3 is compressed; Figure 2 , Figure 5 and Figure 7When the umbrella pole anchor rib 3 is not pressed, the first elastic member 9.3 drives the limit umbrella pole 9.1 to unfold under the driving force of elastic force, and can even unfold to the horizontal. After unfolding, the size of the first elastic member 9.3 is much larger than the passable width of the limit member 20, and the point of action of the limit member 20 on the limit umbrella pole 9.1 is a laborious lever, and it is difficult for an external force to drag the limit umbrella pole 9.1 outward, thereby fixing the limit umbrella pole 9.1 on one side of the limit member 20 and fixing the position of the umbrella pole anchor rib 3. It is not difficult for those skilled in the art to see that when the limiting umbrella rod 9.1 is pressed into the sleeve 11, the first force arm of the sleeve 11 on the connection point between the limiting umbrella rod 9.1 and the umbrella rod anchor rib 3 is greater than the second force arm of the first elastic member 9.3 on the connection point between the limiting umbrella rod 9.1 and the umbrella rod anchor rib 3, and the second force of the first elastic member 9.3 on the connection point between the limiting umbrella rod 9.1 and the umbrella rod anchor rib 3 is greater than the third force arm of the limiting member 20 action point on the connection point between the limiting umbrella rod 9.1 and the umbrella rod anchor rib 3, so that the difficulty of controlling the expansion / contraction of the limiting umbrella rod 9.1 is the most difficult at the action point of the limiting member 20, the first elastic member 9.3 is moderately difficult, and the sleeve 11 is the easiest, so that those skilled in the art can drive the limiting umbrella rod 9.1 to fold by lightly pressing down, but it is extremely difficult to pull out the umbrella rod anchor rib 3 directly because the force arm of the first elastic member 9.3 is longer. As one embodiment, the action point of the limiting member 20 refers to the edge of the ring formed by the limiting member 20 for the umbrella pole anchor 3. As one embodiment, the sleeve 11 controls the end of the limiting umbrella pole 9.1 away from the connection point between the limiting umbrella pole 9.1 and the umbrella pole anchor 3 to achieve a larger force arm to control the limiting umbrella pole 9.1 to be retracted.

[0030] It is not difficult for those skilled in the art to see that when the limiting umbrella rod 9.1 is retracted in the sleeve 11, there are two situations: 1. The limiting umbrella rod 9.1 is retracted to a size that can pass through the limiting member 20; 2. The limiting umbrella rod 9.1 is retracted but still cannot pass through the limiting member 20 before the umbrella rod anchor 3 is subjected to a pulling force. However, at this time, since the limiting umbrella rod 9.1 has been partially retracted, the difference between the second force arm and the third force arm is reduced, and the sleeve 11 also refuses to expand the limiting umbrella rod 9.1. At this time, the limiting umbrella rod 9.1 can be further driven to retract by the pulling force of the umbrella rod anchor 3 until it can pass through the limiting member 20.

[0031] So far, this embodiment has achieved the goal that the umbrella pole anchor 3 is difficult to fall out when being dragged by the anchored object by constructing an ingenious force arm size relationship. The umbrella pole anchor 3 can only be pulled out by manually pressing the umbrella pole anchor 3, and based on the change of the force arm difference when the limiting umbrella pole 9.1 is retracted, it becomes easy to pull out the umbrella pole anchor 3.

[0032] This embodiment is further developed, considering that the size of the limit umbrella rod 9.1 in the unfolded state may be larger than the sleeve 11, which makes it difficult to be pressed into the sleeve 11. As one of the embodiments, refer to Figure 1 , Figure 2 , Figures 4 to 7 The sleeve 11 includes a sleeve wall 11.2; the umbrella-shaped frame rib 9 also includes a guide umbrella rod 9.2 rotatably connected to the limiting umbrella rod 9.1; when the limiting umbrella rod 9.1 is unfolded, the guide umbrella rod 9.2 abuts against the sleeve wall 11.2, and when the umbrella-shaped frame rib 9 is pressed into the sleeve 11, the guide umbrella rod 9.2 guides the limiting umbrella rod 9.1 to enter the sleeve 11, and the limiting umbrella rod 9.1 is retracted under the pressure of the inner wall of the sleeve wall 11.2.

[0033] refer to Figure 2 and Figure 5 2, when the angle between the limit umbrella rod 9.1 and the guide umbrella rod 9.2 is too small, it is easy to cause the limit umbrella rod 9.1 and the guide umbrella rod 9.2 to overlap when the limit umbrella rod 9.1 is pressed down, causing the guide umbrella rod 9.2 to turn out of the sleeve 11. As one of the embodiments, the rotation connection point of the limit umbrella rod 9.1 and the guide umbrella rod 9.2 is provided with a third clamping member, and the third clamping member is used to prevent the angle between the guide umbrella rod 9.2 and the limit umbrella rod 9.1 from being less than the dead threshold; as one of the embodiments, the rotation connection point of the limit umbrella rod 9.1 and the guide umbrella rod 9.2 is provided with a third elastic member, and the third elastic member is used to drive the guide umbrella rod 9.2 and the limit umbrella rod 9.1 to expand, so that there is always a tendency to expand between the limit umbrella rod 9.1 and the guide umbrella rod 9.2, so as to improve the guiding efficiency of the guide umbrella rod 9.2, and also ensure that the limit umbrella rod 9.1 and the guide umbrella rod 9.2 are in contact with the umbrella rod anchor 3 when the umbrella-shaped frame ribs 9 are folded. As one embodiment, the third elastic member may be a spring.

[0034] It is not difficult for a person skilled in the art to see that the process of the umbrella-shaped frame ribs 9 being unfolded / folded is also the process of the umbrella-shaped frame ribs 9 and the sleeve 11 approaching and moving away from each other. Figures 1 to 3 The sleeve 11 includes a sleeve bottom wall 11.1, and the sleeve bottom wall 11.1 is provided with a locking hole 12; one end of the umbrella pole anchor rib 3 is connected to the locking structure 16 through the first rotating shaft, and the locking structure 16 matches the locking hole 12; when the umbrella-shaped frame rib 9 is pressed into the sleeve 11, the locking structure 16 passes through the locking hole 12, and the first rotating shaft is rotated to make the locking structure 16 and the locking hole 12 be locked, so as to prevent the guide umbrella pole 9.2 from being separated from the sleeve wall 11.2.

[0035] When in use, the umbrella pole anchor rib 3 is rotated to align the locking hole 12 with the locking structure 16, and the locking structure 16 is pressed into the locking hole 12 and then rotated so that the locking structure 16 cannot escape from the locking hole 12, thereby limiting the maximum distance between the umbrella-shaped frame rib 9 and the sleeve 11. Figure 6 , ensure that the umbrella-shaped frame reinforcement 9 can be pressed into the sleeve 11; when recovering, rotate the umbrella pole anchor reinforcement 3 to align the positioning hole 12 with the positioning structure 16, and then pull out the umbrella pole anchor reinforcement 3, which can be referred to Figure 7 .

[0036] As one example, refer to Figure 6 , further comprising a second limit plate 14 and a second elastic member 13, the second limit plate 14 being connected to the umbrella-shaped frame rib 9, the second limit plate 14 being elastically connected to the sleeve 11 through the second elastic member 13, the second elastic member 13 being used to overcome the influence of gravity so that the umbrella-shaped frame rib 9 and the sleeve 11 are spaced a set distance apart to keep the umbrella-shaped frame rib 9 in an unfolded state. As one embodiment, the second elastic member 13 can be a spring. As one embodiment, the second limit plate 14 is arranged on the umbrella pole anchor rib 3 to achieve connection with the umbrella-shaped frame rib 9.

[0037] As one embodiment, the sleeve bottom wall 11.1 should be at a certain distance from the edge of the sleeve wall 11.2, so that the locking structure 16 can be pressed down a small section and then the umbrella pole anchor 3 can be rotated.

[0038] As one example, refer to Figure 5 and Figure 7 The ground anchor also includes a first limit plate 15, which is arranged on the umbrella pole anchor rib 3. The first limit plate 15 is adjacent to the umbrella frame rib 9. The first limit plate 15 is used to prevent the expansion angle of the limit umbrella pole 9.1 from exceeding the upper limit threshold.

[0039] As one embodiment, on the umbrella pole anchor rib 3, the umbrella-shaped frame rib 9 is adjacent to a first limiting plate 15 and a second limiting plate 14 above and below.

[0040] As one example, refer to Figure 1 , Figure 2 and Figure 7 The limiting member 20 includes a first hot-melt portion 7, which is used to fix the umbrella pole anchor 3. The first hot-melt portion 7 is in thermal contact with the electric heating element 4. When the electric heating element 4 is energized, the first hot-melt portion 7 softens to facilitate the pulling out of the umbrella pole anchor 3.

[0041] As one embodiment, the electric heating element 4 is a resistance wire wound on the surface of the umbrella pole anchor 3. Figure 2 The electric heating element 4 is powered by the power source 17 to heat and soften the first hot-melt portion 7 on the surface of the umbrella pole anchor 3 .

[0042] As one of the embodiments, the ground anchor also includes a second hot-melt portion 18 for fixing the sleeve 11. A hole can be opened on the anchoring foundation 19, and the sleeve 11 is fixed at the bottom of the hole through the second hot-melt portion 18. At the same time, a part of the electric heating element 4 is wrapped around the surface of the sleeve 11 to facilitate the recovery of the sleeve 11 after the second hot-melt portion 18 is melted.

[0043] As one embodiment, the limiting member 20 also includes a grouting sleeve 6 and a hard part 8. The inner wall of the hard part 8 is the grouting sleeve 6. The first hot melt part 7 is installed in the grouting sleeve 6. The inner diameter of the hard part 8 should be smaller than the unfolding radius of the umbrella-shaped frame rib 9.

[0044] As one embodiment, the radius of the second elastic member 13 is smaller than the outer diameter of the locking structure 16 , so that the second elastic member 13 can be taken out together when the umbrella pole anchor 3 is pulled out.

[0045] As one embodiment, the hard part 8 is made of epoxy resin mortar, and the first hot-melt part 7 is made of epoxy resin.

[0046] As one example, refer to Figure 3 The locking structure 16 adopts a T-shaped piece, and the locking hole 12 adopts a T-shaped hole.

[0047] As one example, refer to Figure 1 , the isolator 5 should be sleeved on the umbrella pole anchor 3, but the inner diameter of the isolator 5 is smaller than that of the isolator 5, the isolator 5 and the adjacent first limit plate 15, and the isolator 5 is used to isolate the first hot melt part 7 from the umbrella frame 9 during injection molding. As one embodiment, the isolator 5 is geotextile. Embodiment 3
