[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] This embodiment provides a foldable anchor, such as Figures 1-7 As shown, the anchor includes a frame 1 and multiple anchor plates 3. Multiple connecting shafts 4 are mounted on the frame 1. The frame serves as the main support structure for the anchor, providing stability. Each anchor plate 3 is rotatably connected to one connecting shaft 4. A positioning groove 132 is provided on one side of the frame 1 along one of the connecting shafts 4. When the anchor plate 3 is in the open state, it rotates to the outside of the frame 1 and is confined within the positioning groove 132. When the anchor plate 3 is in the folded state, it rotates to the inside of the frame 1.

[0030] In this embodiment, the foldable anchor is rotatably connected to the connecting shaft 4 via an anchor leaf 3. When in use, the anchor leaf 3 can rotate to extend beyond the frame 1, allowing it to embed into the underwater soil layer. The anchor leaf 3 is confined within the positioning groove 132, maintaining a stable open state. Even under disturbance, it remains fully extended, achieving reliable anchoring and thus providing anti-interference effects. When storing, the anchor leaf 3 is rotated to the inside of the frame 1, folding it to reduce space occupation and facilitate carrying and storage.

[0031] In a preferred embodiment, frame 1 includes a first side plate 11, a second side plate 12, a first transverse member 13, and a second transverse member 14. The first transverse member 13 and the second transverse member 14 are connected at their respective ends between the first side plate 11 and the second side plate 12, forming a rectangular frame 1 structure. The first side plate 11 and the second side plate 12 are arranged longitudinally, while the first transverse member 13 and the second transverse member 14 are both arranged transversely. The rectangular structure of frame 1 in this embodiment provides strong support and stability.

[0032] In a preferred embodiment, the foldable anchor in this embodiment further includes an elastic element 5. The elastic element 5 is installed on the side of the connecting shaft 4 away from the positioning groove 132. One end of the elastic element 5 abuts against the first transverse member 13 or the second transverse member 14, and the other end of the elastic element abuts against the anchor leaf 3. The elastic element 5 can be a spring and is sleeved on the connecting shaft 4.

[0033] When the anchor needs to be opened, after opening the anchor to a certain angle, the anchor is pressed into the positioning groove of a certain depth by the force of the elastic element 5. When the anchor needs to be folded, the anchor is pressed down manually to compress the spring, so that the anchor is removed from the positioning groove. The anchor is then rotated to the inside of the frame 1 to fold it up. This can significantly reduce the space occupied by the anchor and make it easy to store.

[0034] Preferably, connecting shafts 4 are respectively provided on the front and rear sides of the first transverse member 13 and the second transverse member 14, and the two ends of the connecting shafts 4 are connected to the first side plate 11 and the second side plate 12 respectively. In this embodiment, the rectangular frame is provided with four connecting shafts 4 and four anchor plates. Positioning grooves 132 are provided on the first transverse member 13 and the second transverse member 14. The first transverse member 13 and the second transverse member 14 are both rectangular hollow frame structures 1. The connecting shafts 4 are arranged transversely on the first transverse member 13 and the second transverse member 14.

[0035] In this embodiment, when the anchor leaf is in the open state, such as Figure 1As shown, the tips of the four anchor plates on the front and rear sides of the frame all rotate towards the rear end of the frame, so that the anchor plates are set at an acute angle with the surface of the frame, which makes it easier for the anchor plates to be embedded in the underwater soil layer.

[0036] Preferably, such as Figure 3 and Figure 5 As shown, the anchor leaf 3 is a plate-like structure with pointed tips 32 formed by multiple triangular connections, which allows the anchor leaf to easily embed itself into the mud and sand on the seabed. The pointed tips 32 of the anchor leaf 3 on the first transverse member 13 and the anchor leaf 3 on the second transverse member 14 are staggered, making the pointed tips 32 evenly and densely distributed, which is more conducive to embedding into the mud and sand on the seabed during use, and increases grip and stability. In addition, when the anchor is stored, the anchor leaf is folded inside the frame to avoid mutual interference between the anchor leaf 3 on the first transverse member 13 and the anchor leaf 3 on the second transverse member 14.

[0037] Preferably, such as Figure 1 As shown, clearance windows 131 are provided on both the front and rear sides of the first horizontal member 13 and the second horizontal member 14. The connecting shaft 4 passes through the clearance windows 131 on both the front and rear sides of the first horizontal member 13 and the second horizontal member 14. The connecting seat 31 of the anchor page 3 is connected to the connecting shaft 4 at the clearance window 131, so that the rotation of the anchor page 3 is not affected by the frame, and the structure is compact, increasing the space utilization rate.

[0038] In a preferred embodiment, the foldable anchor of this embodiment further includes an anchor bolt assembly 2, which includes a first anchor bolt 21 and a second anchor bolt 22. The first anchor bolt 21 is connected to the second transverse member 14, and the second anchor bolt 22 is foldably connected to the first anchor bolt 21 on the outside of the frame 1. The tail end of the second anchor bolt 22 is provided with a bolt hole 23 for connecting to an anchor chain or anchor rope. The foldable connection between the second anchor bolt 22 and the first anchor bolt 21 allows the anchor bolt assembly to be shorter when stored, facilitating storage.

[0039] As a preferred embodiment, such as Figure 5 As shown, the first anchor bolt 21 is longitudinally positioned through the middle of the second transverse member 14, and the ends of the first anchor bolt 21 and the second anchor bolt 22 near the first anchor bolt 21 can be retracted into or protrude from the frame 1. When the anchor is retracted, the first anchor bolt 21 and the second anchor bolt 22 are retracted into the frame 1 to reduce the length of the anchor bolt assembly protruding from the frame.

[0040] As a preferred embodiment, such as Figure 4 As shown, the first anchor rod 21 and the second anchor rod 22 are connected by locking bolts 24. Figure 2As shown, a guide hole 141 adapted to the anchor bolt assembly 2 and the locking bolt 24 is provided on the second transverse member 14. When the locking bolt 24 is aligned with the guide hole 141, the second anchor bolt 22 can be retracted into the frame 1 through the guide hole 141. The anchor bolt assembly can rotate within the guide hole 141. A bolt and a washer 25 are connected to the end of the first anchor bolt 21 away from the second anchor bolt 22. The area of ​​the washer 25 is larger than the guide hole 141, so that the end of the first anchor bolt 21 away from the second anchor bolt 22 can be confined within the frame to prevent the anchor bolt assembly from falling off.

[0041] In this embodiment, when the anchor is not in use, the anchor bolt assembly can be retracted into the frame, and the spring can be manually pressed to fold the anchor leaf. The folded anchor can significantly reduce the space occupied and make it easy to store.

[0042] Preferably, the frame and anchor plates are made using an aluminum extrusion process, making them lighter and easier to manufacture.

[0043] The anchor of this embodiment has the following advantages: Convenient storage: The folding function of the anchor leaf and anchor bolt assembly minimizes space occupation when not in use, making it easy to carry and store. High applicability: The anchor bolt assembly can be adjusted in length and angle according to usage needs, improving applicability. High reliability: In the unfolded state, the anchor leaf is spring-loaded and secured in the frame's limiting groove, maintaining a fully unfolded state even after disturbance, enhancing anchoring reliability. Lightweight: By preferentially employing an aluminum extrusion process, the overall weight of the anchor is reduced, making it easy for users to carry and use in small vessels, shallow waters, and temporary use scenarios.

[0044] 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 modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
