Description

Technical Field

[0001] This utility model relates to the field of fishing accessories technology, and in particular to a bearing swivel ring. Background Technology

[0002] With the increasing number of fishing enthusiasts, fishing has become a daily activity suitable for everyone. During fishing, when a fish is hooked, it struggles, causing the hook to spin and the fishing line to twist and knot, potentially leading to breakage. To prevent this, a swivel is typically added between the hook and the line. The swivel's function is to prevent the hook's rotation from being transmitted to the line, ensuring it doesn't twist or knot. Commercially available swivels generally consist of an upper swivel, a lower swivel, and a sleeve. The upper and lower swivels are rotatably connected to the sleeve, allowing them to rotate independently relative to the sleeve. However, due to their small size, this swivel structure is currently relatively simple and inefficient to install, lacking flexibility and ease of installation. Furthermore, it is prone to wear and tear over time, resulting in a shorter lifespan. Utility Model Content

[0003] The purpose of this invention is to design a bearing ring to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs a bearing ring, including a spindle-shaped cylindrical body with a hollow interior and openings at the top and bottom. The cylindrical body includes a main body and a constricted part. The main body is spindle-shaped, and the upper end of the constricted part is integrally connected to the lower end of the main body. The lower end of the constricted part serves as the lower opening of the cylindrical body. A sleeve is fitted at the upper opening of the cylindrical body with clearance, and the sleeve has a through hole communicating with the interior of the cylindrical body.

[0005] It also includes an upper rotating ring and a lower rotating ring. The upper rotating ring includes an upper ring and an upper rotating rod. The upper rotating rod passes through the sleeve and is rotatably connected to the main body. One end of the upper rotating rod located inside the main body forms a first outwardly expanded end with a diameter larger than that of the upper rotating rod. The space enclosed by the first outwardly expanded end, the inner wall of the main body, the upper rotating rod, and the sleeve is provided with balls that assist the rotation of the upper rotating rod. The other end of the upper rotating rod protrudes outside the sleeve and is connected to the upper ring.

[0006] The lower rotating ring includes a lower ring and a lower rotating rod. The lower rotating rod is rotatably connected to the contraction section. One end of the lower rotating rod located inside the contraction section forms a limiting connection with the contraction section and is rotatably connected. The other end of the lower rotating rod protrudes from the contraction section and is connected to the lower ring.

[0007] Preferably, the lower ring can be a closed ring buckle, an open hook buckle, or a self-locking hook buckle.

[0008] Further optimization involves fitting a connecting tube onto the closed ring buckle, with limiting protrusions on the outer wall of the connecting tube located on both sides of the closed ring buckle.

[0009] Preferably, the outer peripheral wall of the sleeve is provided with a tapered stepped surface along the axial direction, and the inner wall of the upper opening of the cylinder is provided with a tapered mounting cavity. The tapered stepped surface and the tapered mounting cavity are adapted to each other, so that the sleeve is fitted into the upper opening of the cylinder.

[0010] Further optimization involves extending the end of the upper rotating rod to the upper end of the contracted portion, so that the first expanding end is close to the upper end of the contracted portion, thereby limiting the movement of the ball within the space enclosed by the first expanding end, the inner wall of the main body, the upper rotating rod, and the sleeve.

[0011] Preferably, the lower rotating rod forms a second outward expansion end at one end of the contraction portion, and the second outward expansion end forms a movable fit with the interior of the contraction portion.

[0012] The technical advantages of this invention are as follows: the upper and lower rotating rings are rotatably connected to both ends of the cylinder, and a sleeve is press-fitted between the upper rotating ring and the cylinder. The sleeve facilitates the installation of the upper and lower rotating rings. Ball bearings are provided between the sleeve and the upper rotating ring, allowing the upper rotating ring to rotate flexibly while preventing wear on the upper rotating ring and avoiding twisting and knotting of the fishing line. The cylinder includes a main body and a constricted part. The upper rotating ring is installed in the main body, and the lower rotating ring is installed in the constricted part. The outer diameter of the constricted part is smaller than that of the main body. During the insertion of the upper rotating ring, the top of the upper rotating ring will abut against the connection between the main body and the constricted part, allowing the upper rotating ring to be directly inserted and abutted without the need to control the insertion depth of the upper rotating ring. This makes installation more convenient and efficient, and the overall structure is smaller in size. Attached Figure Description

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] This utility model includes a cylindrical body, which is spindle-shaped in appearance. The interior of the cylindrical body is hollow and has openings at the top and bottom. The cylindrical body includes a main body 11 and a constricting part 12. The main body 11 is spindle-shaped in appearance. As the name suggests, the outer diameter of the constricting part 12 is smaller than that of the main body 11, so that the constricting part 12 is constricted relative to the main body 11. The upper end of the constricting part 12 is integrally connected to the lower end of the main body 11. The lower end of the constricting part 12 serves as the lower opening of the cylindrical body 1. A sleeve 2 is fitted at the upper opening of the cylindrical body 1 with a gap. That is, the sleeve 2 is installed at the upper opening of the cylindrical body 1. The center of the sleeve 2 is provided with a through hole 21 that communicates with the interior of the cylindrical body 1. The advantage of the lower end being designed to be constricted is that it provides a certain limit to the lower rotating rod 42, so that the lower rotating rod 42 will not swing arbitrarily, and the overall appearance structure is more slender.

[0024] Furthermore, the outer peripheral wall of the sleeve 2 is provided with a conical stepped surface 22 along the axial direction. The conical stepped surface 22 is a two-section stepped surface. The inner wall of the upper opening of the cylinder 1 is provided with a conical mounting cavity 13. The conical stepped surface 22 and the conical mounting cavity 13 are interlocked and adapted to each other, so that the sleeve 2 is fitted at the upper opening of the cylinder 1.

[0025] This utility model also includes an upper rotating ring 3 and a lower rotating ring 4. The upper rotating ring 3 includes an upper ring 33 and an upper rotating rod 32. The upper ring 33 and the upper rotating rod 32 are integrally connected. The upper rotating rod 32 passes through the sleeve 2 and is rotatably connected to the main body 11. That is, one end of the upper rotating rod 32 is located inside the main body 11. This end of the upper rotating rod 32 forms a first outwardly expanded end 31 with a diameter larger than that of the upper rotating rod 32, so that the upper rotating rod 32 can be movably connected to the cylinder 1. At the same time, a limit is formed between the upper rotating rod 32 and the cylinder 1 to prevent the upper rotating rod 32 from detaching from the cylinder 1.

[0026] The internal space of the cylinder 1 is relatively small. When the upper rotating ring 3 is movably connected to the upper opening of the cylinder 1, the first outwardly expanding end 31 of the upper rotating ring 3 approaches or abuts the end of the contracted part 12. There is a gap between the first outwardly expanding end 31 and the inner wall of the main body 11 of the cylinder 1. At this time, the first outwardly expanding end 31, the inner wall of the main body 11, the upper rotating rod 32 and the sleeve 2 form an annular space. A ball bearing 5 is provided in the annular space. The ball bearing 5 can roll in the annular space to assist the upper rotating rod 32 in rotating. It should be noted that since the first outwardly expanding end 31 approaches or abuts the end of the contracted part 12, the annular space is very stable. In particular, after the ball bearing 5 is installed, the ball bearing 5 also plays a locking role, so that the upper rotating ring 3 will not easily detach from the cylinder 1. The other end of the upper rotating rod 32 is exposed outside the sleeve 2 and connected to the upper ring 33.

[0027] The lower rotating ring 4 includes a lower ring 43 and a lower rotating rod 42. The lower rotating rod 42 forms a second outwardly expanding end 41 at one end of the contraction part 12. A gap is left between the second outwardly expanding end 41 and the inner wall of the contraction part 12, so that the lower rotating rod 42 and the contraction part 12 form a movable fit, similar to the connection method of the upper rotating rod 32. The lower rotating rod 42 is rotatably connected to the contraction part 12. That is, the lower rotating rod 42 is both rotatably connected to the contraction part 12 and limited by the contraction part 12 to prevent the lower rotating rod 42 from disengaging from the contraction part 12. The other end of the lower rotating rod 42 is exposed in the contraction part 12 and connected to the lower ring 43.

[0028] Furthermore, the lower ring 43 can be a closed ring, an open hook, or a self-locking hook, meaning that the lower ring 43 can be freely selected in any model to adapt to different usage scenarios.

[0029] like Figure 1 and 2 As shown, the closed-loop buckle is a ring-shaped structure, which is integrated with the lower rotating rod 42. The fishing line is directly tied to the ring or wrapped around the lower rotating rod 42 near the lower ring 43.

[0030] like Figure 3 and 4 As shown, the open-type hook is a hook structure used to directly hook onto the object to be tied or the fishing line, or to wrap the fishing line around and tie it.

[0031] like Figure 5 and 6 As shown, the self-locking hook has a hook structure, and the end of the hook structure forms an elastic end that is in constant contact with the hook structure. When the binding material or fishing line is hooked onto the hook, the end of the hook tightly abuts against the hook structure to form a seal, thereby locking.

[0032] Among them, such as Figure 7 and 8 As shown, a connecting tube 6 can also be fitted onto the closed ring. The outer wall of the connecting tube 6 has limiting protrusions 61 on both sides of the closed ring, so that the closed ring is limited to the outer wall of the connecting tube 6, preventing the closed ring from moving along the axial direction of the connecting tube 6, so that the closed ring can only rotate circumferentially along the connecting tube 6. The connecting tube 6 is usually a sleeve, used to connect other tubes or lines.

[0033] The assembly method of this product is as follows: first, the upper rotating ring 3 and the ball bearing 5 are installed into the main body 11 of the cylinder 1. The first outwardly expanding end 31 of the upper rotating ring 3 is close to or abuts the end of the contracting part 12. That is, it is very convenient to install the upper rotating ring 3. It can be directly inserted to the bottom. That is, the first outwardly expanding end 31 of the upper rotating ring 3 abuts the end of the contracting part 12. Due to the large space inside the cylinder 1, when inserting the upper rotating ring 3, it is necessary to lift or pre-fix the upper ring 33 of the upper rotating ring 3 so that the upper rotating ring 3 is located at the upper opening of the cylinder 1. Then, the sleeve 2 can be installed.

[0034] This invention employs an upper rotating ring 3 and a lower rotating ring 4 that are rotatably connected to the cylinder 1. This design is not only simple in structure and easy to assemble, but also highly flexible. Furthermore, the design of the sleeve 2 facilitates overall assembly and reduces friction between the upper rotating ring 3 and the cylinder 1. Therefore, both the upper rotating ring 3 and the lower rotating ring 4 can rotate freely, preventing the connected fishing line from twisting and tangling due to the fish causing the hook to spin.

[0035] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
