Abstract
Description
Technical Field
[0001] This utility model relates to the field of fishing reel technology, and in particular to a magnetic braking mechanism for a fishing reel. Background Technology
[0002] To prevent the fishing reel from releasing line too quickly when casting, a braking mechanism needs to be installed inside the reel to slow it down, and magnetic braking mechanisms are widely used due to their high stability.
[0003] Most existing magnetic braking mechanisms use multiple magnetic beads mounted on an arc-shaped frame. The arc-shaped frame is mounted on the magnetic base via a centrifugal assembly. The arc-shaped frame moves outward due to centrifugal force, increasing the intensity of the magnetic lines cut by the spool and thus providing braking force. However, because some of the magnetic lines cannot effectively engage the spool, the overall magnetic force threshold is relatively low, resulting in poor deceleration. Furthermore, installing multiple magnetic beads is complex, and the arc-shaped frame structure also becomes more complex due to the need to install multiple magnetic beads, leading to high overall cost of the fishing reel. Summary of the Invention
[0004] The purpose of this invention is to provide a magnetic braking mechanism for fishing reels, which can solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a magnetic braking mechanism for a fishing reel, comprising a reel body, a metal spool, and a magnetic base, wherein the metal spool is rotatably connected to the reel body;
[0006] The lower end of the magnetic base is fitted with an annular magnet.

The upper part of the metal spool has a first cutting circular surface opposite to the annular magnet and a second cutting circular surface opposite to the arc-shaped magnet.
[0007] The upper end of the metal spool is covered with a spool cover, which is installed on the spool body. A mounting post extends downward from the middle of the spool cover. The magnetic seat is fitted onto the mounting post and is driven by a lifting drive mechanism to move up and down along the mounting post. After the magnetic seat moves down, the annular magnet extends into the first cut circular surface, and the arc-shaped magnet extends into the second cut circular surface. The lifting drive mechanism is installed on the spool body or the spool cover.
[0008] Preferably, the lifting drive mechanism includes a lifting cylinder and a dial located at the upper end of the lifting cylinder.

[0016] Preferably, the arc-shaped plate is provided with an arc-shaped groove, and the arc-shaped magnet is a single magnet glued to the arc-shaped groove, or the arc-shaped magnet is multiple magnets glued side by side to the arc-shaped groove.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] like Figures 1-8 As shown, this utility model provides a magnetic braking mechanism for a fishing reel, including a reel body 1, a metal spool 2, and a magnetic base 3, wherein the metal spool 2 is rotatably connected to the reel body 1;
[0026] The lower end of the magnetic base 3 is fitted with an annular magnet 4. An arc plate 5 is provided on each side of the middle part of the magnetic base 3. An arc magnet 6 is installed on the arc plate 5. The upper part of the metal spool 2 has a first cutting circular surface 7 opposite to the annular magnet 4 and a second cutting circular surface 8 opposite to the arc magnet 6.
[0027] The upper end of the metal spool 2 is covered with a spool cover 9, which is installed on the spool body 1. A mounting post 10 extends downward from the middle of the spool cover 9. The magnetic seat 3 is fitted onto the mounting post 10 and is driven by a lifting drive mechanism to move up and down along the mounting post 10. After the magnetic seat 3 moves down, the annular magnet 4 extends into the first cut circular surface 7, and the arc-shaped magnet 6 extends into the second cut circular surface 8. The lifting drive mechanism is installed on the spool body 1 or the spool cover 9.
[0028] In use, this invention uses a lifting drive mechanism to move the magnetic base 3 up and down. When the magnetic base 3 descends, the annular magnet 4 extends into the first cutting circular surface 7, and the arc-shaped magnet 6 extends into the second cutting circular surface 8. As the metal spool 2 rotates, the first cutting circular surface 7 cuts the magnetic lines of force of the annular magnet 4, and the second cutting circular surface 8 on the metal spool 2 cuts the magnetic lines of force of the arc-shaped magnet 6. The magnetic flux from the dual magnetic cutting is superimposed, thereby enhancing the overall magnetic force threshold and ensuring the deceleration effect of the braking mechanism on the metal spool 2. As the magnetic base 3 descends, the area of the metal spool 2 cutting the magnetic lines of force of the two types of magnets increases, thereby improving the braking effect of the braking mechanism. Conversely, the braking effect weakens, allowing for on-demand adjustment of the braking force on the rotating metal spool 2. The annular magnet 4 is generally multi-pole magnetized, with multiple magnetic poles charged on the same magnetic ring, with N and S poles spaced alternately, thus forming multiple sets of magnetic lines of force for better braking effect. A ring magnet 4 and an arc magnet 6 are set on the magnetic base 3. The structure of the magnetic base 3 is relatively simple, the installation of the magnets is also relatively simple, and the cost of the entire fishing reel is low.
[0029] Preferably, the lifting drive mechanism includes a lifting cylinder 11 and a dial 12 located at the upper end of the lifting cylinder 11. The lifting cylinder 11 is rotatably mounted on the spool cover 9 via a lifting shaft 13. The dial 12 extends at least partially beyond the spool body 1. A spiral groove 14 is provided on the outer wall of the lifting cylinder 11. Three guide rods 15 extend upward from the upper end of the magnetic base 3. The spool cover 9 has three guide holes 16 corresponding to the guide rods 15. The guide rods 15 pass through the guide holes 16 and slide within them. A slider 17 protrudes from the upper end of one of the guide rods 15 and slides within the spiral groove 14. Turning the dial 12 rotates the lifting cylinder 11, and the slider 17 slides within the spiral groove 14, thereby driving the magnetic base 3 to move up and down. The structure is simple, with three guide rods 15 that slide in conjunction with their corresponding guide holes 16, ensuring smooth movement of the magnetic base 3.
[0030] Preferably, the lifting cylinder 11 and the dial 12 are integrally formed, resulting in a simple structure.
[0031] Preferably, a positioning disk 18 is provided at the lower end of the lifting shaft 13. The positioning disk 18 has several positioning grooves 19 evenly distributed in a ring. An elastic positioning post 20 is provided on the lifting cylinder 11. The elastic positioning post 20 is placed in one of the positioning grooves 19. During the rotation of the lifting cylinder 11, the elastic positioning post 20 on the lifting cylinder 11 moves from the previous positioning groove 19 to the next positioning groove 19, thereby realizing the positioning of the magnetic seat 3 after the lifting gear is adjusted.
[0032] Preferably, the metal spool 2 is made of aluminum alloy, which has good magnetic conductivity and is lightweight.
[0033] Preferably, the spool cover 9 is fixed to the spool body 1 by three screws, which ensures a firm fixation and stable structure.
[0034] Preferably, the upper part of the magnetic base 3 extends outward to form a mounting base 21. Below the mounting base 21 is an annular cover plate 22 fitted over the magnetic base 3. The arc-shaped plate 5 is located between the mounting base 21 and the annular cover plate 22. The annular cover plate 22 is fixed to the mounting base 21 by bolts. Corresponding positions on the annular cover plate 22 and the mounting base 21 are provided with hinge holes 23 and strip holes 24. The head of the arc-shaped plate 5 is rotatably mounted in the hinge hole 23 via a hinge shaft 25, and the tail of the arc-shaped plate 5 is slidably mounted in the strip hole 24 via a limiting shaft 26. A reset element is provided between the tail of the arc-shaped plate 5 and the mounting base 21. When the metal spool 2 rotates at high speed, the limiting shaft 26 on the arc-shaped plate 5 moves outward along the strip hole 24 under centrifugal force, thus approaching the inner wall of the metal spool 2. The second cutting circular surface 8 of the metal spool 2 can cut the magnetic lines of the arc-shaped magnet 6, increasing its strength and thus providing greater braking force. As the rotational speed of the metal spool 2 gradually decreases, the arc plate 5 is reset under the action of the reset component, thereby moving away from the inner wall of the metal spool 2, thus reducing the braking force and realizing the self-adjustment of the braking mechanism.
[0035] Preferably, the reset component is a spring 27, and the tail of the arc-shaped plate 5 is bent to form a spring seat 28. A spring post 29 is provided on the spring seat 28, and a spring baffle 30 is provided on the mounting base 21 located outside the spring seat 28. One end of the spring 27 is fitted onto the spring post 29, and the other end of the spring 27 abuts against the inner side of the spring baffle 30. Under centrifugal force, the arc-shaped plate 5 approaches the inner wall of the metal spool 2, causing the spring seat 28 to approach the spring baffle 30. The spring 27 is compressed, and after the rotational speed of the metal spool 2 decreases due to the magnetic braking effect, the spring seat 28 resets under the action of the spring 27, thereby moving the arc-shaped plate 5 away from the inner wall of the metal spool 2, thus reducing the braking force and achieving self-adjustment of the braking mechanism.
[0036] Preferably, the lower end of the magnetic base 3 is provided with a mounting shoulder 31, the annular magnet 4 is glued to the mounting shoulder 31, the arc-shaped plate 5 is provided with an arc-shaped groove 32, and the arc-shaped magnet 6 is a single unit glued into the arc-shaped groove 32. Figure 2-7 As shown, or, the arc-shaped magnets 6 are multiple units arranged side-by-side and glued into the arc-shaped groove 32, such as... Figure 8 As shown, four arc-shaped magnets are preferred for better braking effect and easy installation.

They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
