In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] The utility model provides a ground anchor 10.

[0037] See also Figure 1 In one embodiment of the utility model, the ground anchor 10 includes a tie rod assembly 100 and an anchor head 200, the tie rod assembly 100 includes a first tie rod 110 and a second tie rod 120, the first end of the first tie rod 110 is connected to the end of the second tie rod 120, and the end of the second tie rod 120 away from the first tie rod 110 is provided with a rope through hole 121; the anchor head 200 is connected to the second end of the first tie rod 110, and the extension direction of the anchor head 200 is parallel to the second tie rod 120.

[0038] It should be noted that the ground anchor 10 proposed in this solution can not only be used to fix facilities such as road signs and road lights, but can also be used in situations such as rescuing vehicles.

[0039] The technical solution of the present invention is to set a pull rod assembly 100 and an anchor head 200, and the extension direction of the anchor head 200 is parallel to the second pull rod 120 of the pull rod assembly 100. In this way, after the winch rope head is connected to the rope through hole 121 of the second pull rod 120, the anchor head 200 will pass through the pull rod assembly 100 and utilize the tension of the winch rope itself to make the anchor head 200 penetrate into the ground. The positive pressure of the ground anchor 10 can be decomposed into a sinking force and a horizontal tension. The greater the tension on the second pull rod 120, the greater the sinking force of the anchor head 200, thereby making the anchor head 200 tighter and tighter. Moreover, when the second pull rod 120 is subjected to a large tension, the rope end of the second pull rod 120 can also be inserted into the ground, thereby achieving the effect of improving the anchoring force and bearing capacity of the ground anchor 10.

[0040] Secondly, the ground anchor 10 of this solution has a compact structure and is lighter in weight than other ground anchors with complicated structures. When using the ground anchor 10 to rescue a vehicle, the anchor head 200 is inserted into the ground and can be used as a fixed support point. The rope hole 121 of the pull rod assembly 100 is used in conjunction with the rope of the winch, so that the vehicle can be rescued. It can be seen that the ground anchor 10 proposed in this solution is simple to operate and easy to use; moreover, the ground anchor 10 of this solution does not need to be fixed with the help of other objects. Even if the vehicle is trapped in a terrain without anchor support such as a desert, Gobi, or a high mountain, the user can use the ground anchor 10 of this solution to rescue himself.

[0041] When using the ground anchor 10 to fix facilities such as road signs and road lights, the rope is passed through the rope hole 121, and after the road signs and road lights are fixed, the anchor head 200 is finally inserted into the ground. In this way, the ground anchor 10 and the road signs, road lights and other facilities can be fixed. It can be seen that the ground anchor 10 of this solution is simple to operate and easy to operate.

[0042] Optionally, the tie rod assembly 100 further includes a reinforcing rod 130, the two ends of which are respectively connected to the first tie rod 110 and the second tie rod 120. The provision of the reinforcing rod 130 can increase the strength between the second tie rod 120 and the first tie rod 110, thereby improving the overall strength of the tie rod assembly 100 and reducing the probability of fracture of the tie rod assembly 100. Of course, the present design is not limited thereto. In other embodiments, the ground anchor 10 may also not include the reinforcing rod 130, but increase the strength of the tie rod assembly 100 by increasing the connection strength between the first tie rod 110 and the second tie rod 120.

[0043] Reference Figure 2 and Figure 3Further, in the present embodiment, the first end of the first rod 110 and the end of the second rod 120 are rotatably connected, and the reinforcing rod 130 includes a first rod segment 131 and a second rod segment 132 which are rotatably connected to each other, the end of the first rod segment 131 away from the second rod segment 132 is rotatably connected to the first rod 110, and the end of the second rod segment 132 away from the first rod segment 131 is rotatably connected to the second rod 120, so that the rod assembly 100 has a stored state and a deployed state. It can be understood that the first rod segment 131, the second rod segment 132 of the rod assembly 100, and each connection position of the first rod segment 131 and the second rod segment 132 of the reinforcing rod 130 are set to be rotatably connected, so that the rod assembly 100 can be folded and stored when the ground anchor 10 is not in use, which can reduce the storage space of the ground anchor 10 and improve the portability of the ground anchor 10. Of course, the present design is not limited to this. In the second embodiment, the first end of the first rod 110 can also be detachably connected to the end of the second rod 120, and the opposite ends of the reinforcing rod 130 are respectively detachably connected to the first rod 110 and the second rod 120, so that each component can be disassembled through a detachable installation method, which is also convenient for storage and carrying. Of course, the present design is not limited to this. In the third embodiment, the first end of the first rod 110 can also be fixedly connected to the end of the second rod 120, and the opposite ends of the reinforcing rod 130 are respectively fixedly connected to the first rod 110 and the second rod 120.

[0044] The first end of the first pull rod 110 is provided with a mounting portion protruding laterally, and the second pull rod 120 is rotatably connected to the mounting portion, which can improve the foldability of the pull rod assembly 100, thereby reducing the storage space of the pull rod assembly 100 and achieving the effect of being easy to carry.

[0045] In one embodiment, the second pull rod 120 is provided with a connecting portion 122 protruding toward the direction close to the anchor head 200, the end of the reinforcing rod 130 is connected to the connecting portion 122, and the rope through hole 121 is located on the extension line of the reinforcing rod 130; this is conducive to improving the utilization rate of the tension of the winch rope itself, so as to facilitate the use of tension to drive the anchor head 200 into the ground, so that the anchor head 200 is pulled tighter and tighter. Of course, the design is not limited to this. In other embodiments, the end of the reinforcing rod 130 can also be directly connected to the rod body of the second pull rod 120 without providing the connecting portion 122.

[0046] When the reinforcing rod 130 includes a first rod segment 131 and a second rod segment 132 , one end of the second rod segment 132 away from the first rod segment 131 is rotatably connected to the connecting portion 122 .

[0047] In one embodiment, the first rod 110 is provided with a reinforcing angle iron 111, and the reinforcing angle iron 111 extends along the first rod 110. It can be understood that the provision of the reinforcing angle iron 111 can improve the strength of the first rod 110, thereby reducing the probability of the first rod 110 breaking due to excessive tension of the winch rope. Of course, the design is not limited to this. In other embodiments, the strength of the first rod 110 can also be increased by increasing the thickness of the first rod 110.

[0048] Furthermore, a reinforcement plate is provided on the first tie rod 110, and the reinforcement rod 130 is connected to the first tie rod 110 via the reinforcement plate. Specifically, when the reinforcement rod 130 includes a first rod segment 131 and a second rod segment 132, one end of the first rod segment 131 away from the second rod segment 132 is rotatably connected to the reinforcement plate. It can be understood that when the second tie rod 120 receives a tensile force, a part of the tensile force will act on the first tie rod 110 through the reinforcement rod 130, and the tensile force at the connection between the reinforcement rod 130 and the first tie rod 110 is relatively large. Therefore, providing a reinforcement plate at the connection position is beneficial to increasing the strength of the first tie rod 110.

[0049] Reference Figure 1 and Figure 4 Optionally, the anchor head 200 is detachably connected to the first tie rod 110; it can be understood that the purpose of detachably connecting the anchor head 200 to the first tie rod 110 is to separate the anchor 10 and the tie rod assembly 100 when the anchor 10 is not in use, so as to facilitate the storage of the anchor 10. Of course, the present design is not limited to this, and in other embodiments, the anchor head 200 can also be fixedly connected to the first tie rod 110.

[0050] Optionally, the anchor head 200 includes two connected anchor plates 210, which are arranged at an angle, and the anchor plate 210 has an insertion section 211 arranged near the rope through hole 121, and the cross-sectional area of ​​the insertion section 211 gradually decreases in the direction close to the rope through hole 121, and the free end of the insertion section 211 is pointed. It can be understood that the anchor head 200 is arranged as two connected anchor plates 210. This is because when the anchor plate 210 is inserted into the ground, the lateral cross-section of the anchor plate 210 is small, which can reduce the contact area with the soil, thereby reducing the resistance generated during the insertion process, so that the anchor head 200 is inserted into the ground more labor-saving. Of course, the present design is not limited to this. In other embodiments, the anchor head 200 can also be arranged as a cone as a whole.

[0051] It should be noted that the anchor head 200 can be integrally formed, or can be formed by stamping or welding later.

[0052] Among them, the cross-sectional area of ​​the insertion section 211 gradually decreases in the direction close to the rope through hole 121, and the free end of the insertion section 211 is pointed. First, such a shape can reduce the resistance encountered by the anchor head 200 when it is inserted into the soil or rock. Since the cross-sectional area of ​​the tip is small, the contact area with the soil is correspondingly reduced, thereby reducing the friction and making it easier for the anchor head 200 to penetrate the soil. Once the anchor head 10 is inserted into the ground and reaches a certain depth, its shape and position will help the anchor head 200 provide a stable fixing point. Moreover, the shape of the tip helps the anchor 10 to form a firm anchor in the soil to prevent it from loosening or pulling out due to external forces. Secondly, making the free end of the insertion section 211 pointed can concentrate the force applied to the anchor head 200 in a small area, and this concentration of force helps to penetrate hard soil layers or rocks. In contrast, if the free end of the anchor head 200 is flat, the force will be dispersed over a larger area, reducing the penetration effect.

[0053] A weight-reducing notch is also provided on one side of the anchor plate 200 away from the insertion end 211 , which helps to reduce the weight of the ground anchor 10 .

[0054] Optionally, at least one side of each anchor plate 210 is provided with a protrusion 212 or a recess 213 , which can improve the gripping force of the anchor head 200 , thereby increasing the bearing capacity of the ground anchor 10 .

[0055] Furthermore, the anchor plate 210 is provided with a plurality of punching holes, so as to form a protrusion 212 or a recess 213 at the edge of the punching hole by a punching process. It can be understood that by providing the punching holes and punching out the protrusions and recesses 213 at the periphery of the punching holes, the protrusions 212 and recesses 213 are formed in a simple process, and the weight of the ground anchor 10 can be reduced by providing the punching holes. Of course, the present design is not limited thereto, and in other embodiments, a groove or a protrusion can also be provided on the anchor plate 210 by integral casting.

[0056] In this embodiment, there are a plurality of protrusions 212 and recesses 213, respectively, and in the extension direction of the anchor plate 210, the protrusions 212 and recesses 213 are alternately arranged; it can be understood that this can further improve the grip of the anchor plate 210, thereby improving the bearing capacity of the anchor 10. Of course, the design is not limited to this, and in other embodiments, the protrusions 212 and recesses 213 can also be randomly distributed on the anchor plate 210.

[0057] It should be noted that since the recess 213 and the convex portion are formed by a stamping process, the recess 213 appears on one side of the anchor plate 210, while the other side of the anchor plate 210 at this position appears as a convex portion 212. In this way, the recess 213 can be formed on the other side when the convex portion is stamped, which is conducive to reducing the processing technology and thus improving production efficiency.

[0058] Optionally, the anchor head 200 further includes a plurality of reinforcing ribs 220, and opposite ends of the reinforcing ribs 220 are respectively connected to the two anchor plates 210; and / or, the anchor head 200 further includes a reinforcing plate 230, and opposite edges of the reinforcing plate 230 are respectively connected to the two anchor plates 210; it can be understood that this can improve the strength of the anchor head 200.

[0059] Furthermore, the anchor head 200 further includes a handle 240, which is disposed between the two anchor plates 210 and located on a side of the anchor plate 210 away from the pull rod assembly 100; the provision of the handle 240 is conducive to holding the ground anchor 10 and is convenient for taking and placing.

[0060] Among them, the two anchor plates 210 are provided with avoidance openings at the positions corresponding to the handles 240, and the reinforcing plate 230 is provided corresponding to the avoidance openings, which can improve the safety of the handles 240 and prevent the sharp edges of the connection positions of the two anchor plates 210 from injuring the user.

[0061] Reference Figures 5 to 7 Furthermore, the anchor head 200 is provided with at least two insertion tips 260. The two insertion tips 260 are not only helpful for breaking frozen soil, but also help to make the anchor head 200 more stable.

[0062] Furthermore, in the first embodiment, the anchor head 200 includes an anchor plate 210, and the anchor plate 210 is formed with at least two parallel bending portions 260, and the fold line direction of the bending portion 260 is parallel to the length direction of the anchor plate 210, and the insertion tip 250 is formed at the end of each bending portion 260. It can be understood that the anchor head 200 is set to be plate-shaped because the lateral cross-section of the plate is small, which can reduce the contact area with the soil, thereby reducing the resistance generated during the insertion process, so that the anchor head 200 is inserted into the ground more labor-saving.

[0063] Furthermore, the anchor plate 210 can be formed by stamping or integrally cast, which is beneficial to improving the strength of the anchor head 200 .

[0064] In the second embodiment, the anchor head 200 includes at least two parallel anchor columns 270 , and the insertion tip 260 is formed at the end of each anchor column 270 . Such an anchor head 200 is easier to shape.

[0065] Specifically, the anchor column 270 may be configured as a whole in a cone shape, and the anchor column 270 may also include a columnar section and a cone section connected to each other, and the insertion tip 260 is formed in the cone section.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
