Abstract
Description
Technical Field
[0001] This utility model relates to the field of ground anchor technology, and in particular to a ground anchor. Background Technology
[0002] A ground anchor is a device designed to be buried underground to provide a stable connection point for equipment on the ground. In outdoor activities, such as setting up a tent, it is commonly used to secure guy lines to maintain the tent's stability. Common types of ground anchors on the market include tie-down, pole, and helical anchors. These types of ground anchors have relatively simple structures and can effectively maintain tent stability under normal circumstances.
[0003] However, when subjected to excessive wind loads or used on soft surfaces, these types of ground anchors may sway due to external forces, resulting in a weakening of their anchoring force. In extreme cases, the ground anchor may even be completely pulled out, thus rendering the anchoring function completely ineffective. Utility Model Content
[0004] The purpose of this utility model is to provide a ground anchor in order to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A ground anchor includes a main anchor rod, a main pressure plate fixedly connected to the top of the main anchor rod, an inverted U-shaped rod fixedly connected to the top of the main pressure plate, an installation groove on the main anchor rod, a rotating rod rotatably mounted in the middle of the main pressure plate, at least two sets of cross-shaped rotating plates fixedly sleeved on the rotating rod, a linkage groove on the free end of the cross-shaped rotating plate, a third bolt slidingly fitted in the linkage groove, and a second auxiliary anchor rod passing through the main anchor rod connected to the bottom end of the third bolt by thread.
[0007] As a further description of the above technical solution:
[0008] The inverted U-shaped rod has a secondary pressure plate movably sleeved on both vertical ends. Several first secondary anchor rods that penetrate the main pressure plate are fixedly connected to the bottom of the secondary pressure plate near the edge.
[0009] As a further description of the above technical solution:
[0010] A knob is threadedly connected to the sub-pressure plate, and the bottom end of the knob is fixedly connected to the top end of the rotating rod.
[0011] As a further description of the above technical solution:
[0012] The free ends of the main anchor bolt, the first secondary anchor bolt, and the second secondary anchor bolt are all conical structures.
[0013] As a further description of the above technical solution:
[0014] The top of the main anchor rod is provided with an annular groove, and a concave convex ring that mates with the annular groove is recessed downward on the main pressure plate. Several first bolts are connected between the concave convex ring and the annular groove by threaded engagement.
[0015] As a further description of the above technical solution:
[0016] The bottom of the concave convex ring is recessed upwards with a groove, and a second bolt is threadedly connected between the groove and the vertical ends on both sides of the inverted U-shaped rod.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0018] 1. In this utility model, the main anchor rod is inserted into the soil and the main pressure plate is pressed firmly on the ground. Then, the drive rod drives the cross-shaped rotating plate to rotate clockwise. Under the linkage of the linkage groove and the third bolt, the second auxiliary anchor rod is driven to move outward and be inserted horizontally into the soil. This strengthens the longitudinal stability of the main anchor rod and the soil, prevents the main anchor rod from shaking when encountering large external forces, and improves the anchoring effect.
[0019] 2. In this utility model, while rotating the knob drives the rotating rod to rotate, the secondary pressure plate is driven to descend and insert the first secondary anchor rod into the soil based on the threaded transmission. On the one hand, the secondary pressure plate presses tightly against the main pressure plate, improving the pressing effect between the main pressure plate and the ground. On the other hand, it strengthens the lateral firmness between the main anchor rod and the soil, further improving the anchoring effect. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 This utility model provides a technical solution: a ground anchor, including a main anchor rod 1, a main pressure plate 5 fixedly connected to the top of the main anchor rod 1, and an inverted U-shaped rod 10 fixedly connected to the top of the main pressure plate 5. Specifically, the top of the main anchor rod 1 has an annular groove 102, and the main pressure plate 5 has a concave convex ring 2 that mates with the annular groove 102. The concave convex ring 2 and the annular groove 102 are connected by a plurality of first bolts 6 through threaded engagement. The bottom of the concave convex ring 2 has an annular groove that is recessed upwards, and the annular groove and the vertical ends on both sides of the inverted U-shaped rod 10 are connected by second bolts 7 through threaded engagement, which facilitates the assembly and disassembly of the main pressure plate 5 and the inverted U-shaped rod 10, as well as the main pressure plate 5 and the main anchor rod 1.
[0031] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the main anchor rod 1 has an installation groove 101. A rotating rod 3 is rotatably installed in the middle of the main pressure plate 5. At least two sets of cross-shaped rotating plates 12 are fixedly sleeved on the rotating rod 3. A linkage groove 1201 is opened on the free end of the cross-shaped rotating plate 12. A third bolt 11 is slidably fitted in the linkage groove 1201. The bottom end of the third bolt 11 is threadedly connected to a second auxiliary anchor rod 13 that passes through the main anchor rod 1. The main anchor rod 1 is inserted into the soil, and the main pressure plate 5 is pressed tightly onto the ground. Then, the rotating rod 3 drives the cross-shaped rotating plate 12 to rotate clockwise (see reference). Figure 2Under the linkage of the linkage groove 1201 and the third bolt 11, the second auxiliary anchor rod 13 is driven to move outward and horizontally insert into the soil, which strengthens the longitudinal firmness of the main anchor rod 1 and the soil, prevents the main anchor rod 1 from shaking when encountering large external forces, and improves the anchoring effect.
[0032] It should be noted that when the ground anchor is not in use or is removed, the reverse rotation of the swivel rod 3 will retract the second auxiliary anchor rod 13 into the installation groove 101. The free end of the second auxiliary anchor rod 13 is located at the wall thickness of the main anchor rod 1, which facilitates both the removal and storage of the ground anchor.
[0033] Specifically, such as Figure 1 As shown, secondary pressure plates 8 are movably fitted onto the vertical ends of the inverted U-shaped rod 10 on both sides. Several first secondary anchor rods 9, penetrating the main pressure plate 5, are fixedly connected to the bottom edge of the secondary pressure plates 8. A knob 4 is threadedly connected to the secondary pressure plates 8, and the bottom end of the knob 4 is fixedly connected to the top end of the rotating rod 3. When the knob 4 is rotated, the rotating rod 3 is driven to rotate. Based on the threaded transmission, the secondary pressure plates 8 are driven to lower the first secondary anchor rods 9 into the soil. On the one hand, the secondary pressure plates 8 press tightly against the main pressure plates 5, improving the compaction effect between the main pressure plates 5 and the ground. On the other hand, it strengthens the lateral stability between the main anchor rods 1 and the soil, further improving the anchoring effect.
[0034] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the free ends of the main anchor 1, the first secondary anchor 9, and the second secondary anchor 13 are all conical structures, which facilitates the insertion of each anchor into the soil.
[0035] Working principle: In use, firstly, the main anchor rod 1 is inserted into the soil, and the main pressure plate 5 is pressed firmly onto the ground. Then, the drive knob 4 drives the rotating rod 3 and the cross-shaped rotating plate 12 to rotate clockwise. Under the linkage of the linkage groove 1201 and the third bolt 11, the second auxiliary anchor rod 13 is driven to move outward and be inserted horizontally into the soil, which strengthens the longitudinal firmness between the main anchor rod 1 and the soil, prevents the main anchor rod 1 from shaking when encountering large external forces, and improves the anchoring effect. At the same time, based on the threaded transmission, the drive auxiliary pressure plate 8 drives the first auxiliary anchor rod 9 to descend and be inserted into the soil. On the one hand, the auxiliary pressure plate 8 presses tightly against the main pressure plate 5, improving the pressing effect between the main pressure plate 5 and the ground. On the other hand, it strengthens the lateral firmness between the main anchor rod 1 and the soil, further improving the anchoring effect.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
