Technical Field
[0001] This utility model relates to the field of fishing tackle manufacturing technology, specifically to alloy free fishing rig sinker. Background Technology
[0002] Alloy free-floating rig sinker is a fishing accessory suitable for various water conditions. It is small in size and has concentrated weight, allowing it to sink quickly with the bait and maintain its bottom position. It has a stable center of gravity, good resistance to water currents, and is suitable for complex water environments. It is a powerful tool for fishing for bottom-dwelling fish such as bass.
[0003] The existing fishing rigs mostly rely on traditional binding and knotting methods to connect the various parts. First, the fishing line is passed through the hole of the inverted sinker, and then a knot is tied on the fishing line above the inverted sinker to form a stop knot, or the position of the inverted sinker is fixed by using bobbins. For some inverted sinkers with connecting rings, the fishing line needs to be passed through the connecting ring manually and then knotted. When installing, the tightness and position of the knot need to be adjusted repeatedly, and when replacing, the original knot needs to be disassembled. However, traditional connection methods are extremely inefficient. Changing to different weights of sinkers requires time-consuming disassembly and retying of knots, causing you to miss the best fishing opportunity. At the same time, there is a problem with poor connection stability. Knots are easily loosened or detached due to water flow and fish bites, causing the fishing rig to break apart and fish to escape. In addition, the operation is difficult and not very beginner-friendly. Repeated knotting can easily cause wear and tear on the fishing line, shortening its lifespan. Furthermore, the knots may increase water resistance, affecting the natural posture of the fishing rig in the water and reducing the fish-attracting effect.
[0004] Therefore, this utility model provides an alloy free-floating rig with a sinker to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide an alloy free-floating rig sinker to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: The alloy free-floating rig with a sinker includes a swivel, a connecting block, and a counterweight. The swivel is rotatably mounted inside the connecting block, and the counterweight is mounted below the connecting block to ensure flexible rotation between the swivel, the connecting block, and the counterweight, allowing the rig to naturally and realistically present its state in the water. The inner cavity of the counterweight has a groove, and a connecting rod is embedded in the groove. The bottom end of the connecting rod is rotatably connected to the inner cavity of the counterweight, and its top end is rotatably connected to the inner cavity of the connecting rod, allowing the counterweight to swing flexibly at multiple angles to enhance the fish-attracting effect. The counterweight and the connecting rod are both made of alloy material and are integrated into one piece, making them less prone to deformation or breakage. The top of the swivel is movably connected to a connecting component, and the connecting component has a connecting block. The connecting component allows anglers to quickly assemble or switch between different sizes of sinkers as needed. The operation is simple, improves the efficiency of rig adjustment, and saves time.
[0007] As a further embodiment of this utility model, the connecting assembly includes a retaining ring, which is rotatably sleeved on the top of the hanging ring. A fixing plate is fixedly sleeved on the outer wall of the center of the retaining ring. Both the upper and lower ends of the fixing plate are fixedly connected to spiral blocks. A fastening tube for locking the retaining ring is sleeved on the outer wall of each set of spiral blocks.
[0008] As a further embodiment of this utility model, a spiral ring is fixedly installed in the inner cavity of each set of fastening tubes, and a spiral groove matching the spiral block is opened on its inner wall. The two are precisely engaged by threaded connection. A limit plate is fixedly connected to the ends of the two sets of spiral blocks that are far apart, which is used to limit the rotation range of the spiral ring.
[0009] As a further embodiment of this utility model, multiple anti-slip strips are uniformly and firmly fixedly installed on the outer surface of the fastening tube along its axial direction. The anti-slip strips are made of silicone material, which has a certain hardness and coefficient of friction, and protrude from the outer surface of the fastening tube in a strip-shaped structure to form a clear concave-convex structure.
[0010] As a further embodiment of this utility model, a rotating block is fixedly connected to the bottom end of the hanging ring, and an anti-detachment block is fixedly connected to the top end of the connecting rod. The rotating block and the anti-detachment block are both located inside the connecting block, and both are used to prevent the hanging ring and the counterweight from falling off, while ensuring the rotation of the hanging ring and the connecting rod.
[0011] As a further improvement of this utility model, the hanging ring has a hollow interior with a connecting hole for easy threading and fixing of the fishing line. The hanging ring has an elliptical structure and its surface is polished to reduce resistance when moving in water.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this utility model, the fishing rig can be quickly assembled and securely connected through the connecting components. The snap ring is a spring steel figure-eight ring structure. The opening is usually open for easy docking with the connecting ring and the hanging ring. Pressing it can shrink the opening. In conjunction with the twisting of the fastening tube with anti-slip strip, its internal spiral ring and spiral block threadedly engage, converting rotation into axial force to compress the snap ring opening and lock it. The limiting plate prevents it from falling off, ensuring stable connection and simplifying the operation process. The loading, unloading and replacement of the reverse fishing lead can be completed without binding or disassembling the fishing line, and it is convenient to flexibly switch between different weight reverse fishing leads according to needs.
[0013] 2. When in use, this utility model integrates the alloy counterweight and connecting rod into one unit, possessing excellent strength and toughness. It can effectively resist the impact of complex underwater environments and cope with external forces generated by water flow impact and fish bites during fishing, significantly reducing the risk of deformation or breakage, improving the durability and service life of the fishing rig, and adapting to various aquatic environments. At the same time, its non-deformable characteristics ensure precise and reliable rotational connection between the connecting rod, counterweight, and connecting block. Combined with the rotating block and anti-detachment block, it can achieve flexible swinging at multiple angles, preventing fishing line tangling, allowing the fishing rig to naturally present its true state in the water, improving the fish-attracting effect, and avoiding the stability of core functions such as anti-detachment and rotation due to material wear.

Detailed Implementation
[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 , Figure 2 In this embodiment of the utility model, the alloy free fishing rig with a sinker includes a hanging ring 1, a connecting block 2, and a counterweight 3. The hanging ring 1 is rotatably installed in the inner cavity of the connecting block 2, and the counterweight 3 is installed below the connecting block 2 to ensure flexible rotation between the hanging ring 1, the connecting block 2, and the counterweight 3, so that the fishing rig can naturally present a more realistic state in the water. The inner cavity of the counterweight 3 has a groove, and the connecting rod 5 is embedded in the groove. The bottom end of the connecting rod 5 is rotatably connected to the inner cavity of the counterweight 3, and its top end is rotatably connected to the inner cavity of the connecting block 2, so that the counterweight 3 can swing flexibly at multiple angles to enhance the fish-attracting effect. The counterweight 3 and the connecting rod 5 are both made of alloy material, and the two are integrated into one piece, which is not easy to deform or break. The top of the hook 1 is movably connected to the connecting component 6, and the connecting component 6 is threaded through the connecting block 2. The connecting component 6 allows anglers to quickly assemble or switch between different sizes of sinkers as needed. The operation is simple, improves the efficiency of rig adjustment, and saves time. It should be noted that the rotating connection between the swivel 1 and the connecting block 2 ensures that the fishing line can move freely and avoid tangling. The alloy counterweight 3 and connecting rod 5 have excellent strength and toughness, which can effectively resist the impact of complex underwater environments, improve the durability and service life of the fishing rig, and make it suitable for use in a variety of aquatic environments.
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting component 6 includes a retaining ring 601, which is rotatably sleeved on the top of the hanging ring 1. A fixing plate 602 is fixedly sleeved on the outer wall of the center of the retaining ring 601. Both the upper and lower ends of the fixing plate 602 are fixedly connected to a spiral block 603. A fastening tube 604 for locking the retaining ring 601 is sleeved on the outer wall of each set of spiral blocks 603. It should be noted that the retaining ring 601 adopts a figure-eight ring structure, and each end of it near the two sets of spiral blocks 603 has an opening. The retaining ring 601 is made of spring steel, and its elastic properties keep the opening always open, which facilitates the installation of the retaining ring 601, simplifies the alignment and threading steps during installation, eliminates the need to manually adjust the opening state, improves installation efficiency, and the retaining ring 601 has good elastic recovery ability, which can shrink the opening after being pressed and restore the opening to the open state after the external force is removed. It should also be noted that the top of the snap ring 601 is fitted with a connecting ring 605 for fixing the fishing line, and the bottom of the snap ring 601 is movably connected to the hanging ring 1. At the same time, the ends of the two sets of fastening tubes 604 that are far apart are both set as expansion openings. When it is necessary to change the weight of the sinker, simply separate the snap ring 601 from the connecting ring 605, and then press the snap ring 601 to shrink its opening into the expansion opening. As the fastening tube 604 is twisted, it moves along the spiral block 603, which can gradually compress the opening of the snap ring 601 to achieve locking, reduce the opening gap, and achieve quick opening and closing and stable locking. This can not only prevent the connecting ring 605 and the hanging ring 1 from accidentally falling off, ensuring connection stability, but also simplify the loading and unloading process of the sinker and greatly improve the replacement efficiency. Each set of fastening tubes 604 has a spiral ring 606 fixedly installed in its inner cavity, and its inner wall has a spiral groove that matches the spiral block 603. The two are precisely engaged by threaded connection. The ends of the two sets of spiral blocks 603 that are far apart are fixedly connected to a limit plate 607 to limit the rotation range of the spiral ring 606. It should be noted that the threaded engagement between the spiral ring 606 and the spiral block 603 converts the rotational motion of the fastening tube 604 into axial thrust, achieving uniform compression of the opening of the retaining ring 601, ensuring controllable and stable locking force. At the same time, the inner diameter of the spiral ring 606 is smaller than the diameter of the limiting plate 607, so that when the fastening tube 604 is twisted, the spiral ring 606 moves smoothly along the threaded trajectory of the spiral block 603. When the spiral ring 606 moves to fit against the limiting plate 607, the limiting plate 607 will form a limiting block, restricting the movement range of the spiral ring 606, preventing the spiral ring 606 from moving excessively and falling off, ensuring that the locking operation has a clear endpoint, and improving the safety and ease of use. Multiple anti-slip strips 608 are uniformly and firmly fixed on the outer surface of the fastening tube 604 along its axial direction. The anti-slip strips 608 are made of silicone material, which has a certain hardness and coefficient of friction. They protrude from the outer surface of the fastening tube 604 in a strip-like structure, forming a clear concave-convex structure. It should be noted that the core function of the anti-slip strip 608 is to increase the friction between the hand and the fastening tube 604. In fishing scenarios, the user's hands may become slippery due to water, oil, or wearing gloves. The texture formed by the anti-slip strip 608 can effectively overcome the slippage barrier between the hand and the surface of the fastening tube 604, allowing the user to hold and twist the fastening tube 604 more easily and stably, ensuring that it can smoothly drive the spiral ring 606 to complete the locking or unlocking operation of the retaining ring 601, thereby improving the reliability and convenience of operation.
[0022] Please see Figure 2 The bottom end of the hanging ring 1 is fixedly connected to a rotating block 7, and the top end of the connecting rod 5 is fixedly connected to an anti-detachment block 8. The rotating block 7 and the anti-detachment block 8 are both located inside the connecting block 2, and both are used to prevent the hanging ring 1 and the counterweight block 3 from falling off, while ensuring the rotation of the hanging ring 1 and the connecting rod 5. It should be noted that the inner cavity of the connecting block 2 has two sets of T-slots, and the rotating block 7 and the anti-detachment block 8 are respectively embedded in the two sets of T-slots. The outer dimensions of the rotating block 7 match the cavity dimensions of the T-slot, and its outer diameter is larger than the diameter at the connection between the hanging ring 1 and the rotating block 7. The outer dimensions of the anti-detachment block 8 also match the cavity dimensions of the corresponding T-slot, and its outer diameter is larger than the diameter at the connection between the connecting rod 5 and the anti-detachment block 8. This allows the rotating block 7 and the anti-detachment block 8 to rotate freely along the cavity of their respective T-slots, avoiding the tangling of the fishing line or structural jamming caused by the rigid connection of the structure. This improves the flexibility and adaptability during use. At the same time, the mechanical limit is formed by the groove structure of the T-slot and the size difference between the rotating block 7 and the anti-detachment block 8, which can effectively prevent the hanging ring 1 from detaching upward along the axis of the connecting block 2, and at the same time prevent the connecting rod 5 and the counterweight block 3 connected to it from detaching downward along the axis of the connecting block 2. This achieves double anti-detachment protection for the hanging ring 1 and the counterweight block 3, ensuring the stability of the overall structural connection. It should also be noted that the bottom end of the connecting rod 5 is fixedly connected to a locking block 9, and the locking block 9 is correspondingly embedded in the groove of the inner cavity of the counterweight block 3. The inner diameter of the groove is equal to the outer diameter of the locking block 9, ensuring that the locking block 9 can be stably embedded in the groove without radial wobbling, thus ensuring the stability of the basic connection. At the same time, the axial dimension of the groove is greater than the height of the locking block 9 in the same direction, so that an axial gap is formed between the locking block 9 and the inner wall of the groove. This gap provides space for the connecting rod 5 to drive the locking block 9 to make a certain range of axial movement in the groove. It can adapt to the axial force and displacement caused by water flow impact, fish bite and pulling during fishing, avoid the risk of component stress concentration and breakage caused by rigid connection, and improve the adaptability of the overall structure to complex working conditions.
[0023] Please see Figure 2 The hanging ring 1 has a hollow interior with a connecting hole 4, which facilitates the threading and fixing of the fishing line. The hanging ring 1 has an elliptical structure and its surface is polished to reduce resistance when moving in water.
[0024] The working principle of this utility model is as follows: When using this utility model, first tie the fishing line to the connecting ring 605, then connect the two ends of the retaining ring 601 to the connecting ring 605 and the hanging ring 1 respectively. Pressing the retaining ring 601 will shrink the opening, and twisting the fastening tube 604 will cause the spiral groove on the inner wall of the spiral ring 606 to engage with the spiral block 603, thereby driving the spiral ring 606 to move axially and uniformly compress the opening of the retaining ring 601 to achieve locking and prevent the connecting ring 605 and the hanging ring 1 from falling off. Then, the weight of counterweight 3 causes the fishing rig to sink, increasing its attractiveness to fish. Furthermore, the alloy counterweight 3 and connecting rod 5 have excellent strength and toughness, resisting impacts in the water and improving durability. Finally, the swivel 1 is rotatably connected to the connecting block 2 via the rotating block 7 to prevent the fishing line from getting tangled during use. At the same time, the connecting block 2 is rotatably connected to the counterweight block 3 via the anti-detachment block 8, the connecting rod 5, and the locking block 9, which facilitates the flexible rotation and swing of the counterweight block 3, allowing the fishing rig to naturally present its true posture when affected by the water flow.
[0025] 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.
