Description

Technical Field

[0001] The utility model relates to the technical field of fishing reels, in particular to a double-sided magnetic brake mechanism of a fishing reel. Background Art

[0002] In order to prevent the fishing reel from releasing the line too quickly when casting the rod, a brake mechanism needs to be installed inside the fishing reel to slow down the fishing reel. Magnetic brake mechanisms are widely used due to their high stability.

[0003] The magnets of existing magnetic brake mechanisms are mostly installed vertically, that is, the magnetic flux lines of the magnets are perpendicular to the spool. Since part of the magnetic flux lines of the magnets are distributed on the upper side of the spool, they cannot effectively act on the spool, resulting in a small threshold of the overall magnetic force, causing a poor deceleration effect. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a double-sided magnetic brake mechanism for a fishing reel.

[0005] The technical solution of the utility model is: a double-sided magnetic brake mechanism of a fishing reel, including a reel body, a spool and a cylindrical magnetic seat, the top of the cylindrical magnetic seat is connected to the reel body via a lifting drive, the spool is covered on the outside of the cylindrical magnetic seat and is rotatably connected to the reel body, a vertical magnet is arranged on the outside of the cylindrical magnetic seat, a horizontal magnet is arranged on the bottom of the cylindrical magnetic seat, and a conductive plate for cutting the magnetic flux of the horizontal magnet is provided in the spool. By simultaneously arranging the vertical magnet and the horizontal magnet on the magnetic seat, the spool and the conductive plate in the spool cut the magnetic flux at the same time, and the bidirectionally cut magnetic flux is superimposed, thereby enhancing the overall magnetic force threshold and ensuring the deceleration effect of the brake mechanism on the spool.

[0006] Two symmetrically arranged arc-shaped mounting plates are installed on the cylindrical magnetic seat, and the vertical magnet and the horizontal magnet are embedded and installed on the outer side and the bottom of the arc-shaped mounting plates respectively.

[0007] The horizontal magnet is one magnet or a plurality of magnets distributed along the circumferential direction of the outer side of the arc-shaped mounting plate, and the vertical magnet is one magnet or a plurality of magnets distributed along the circumferential direction of the bottom of the arc-shaped mounting plate.

[0008] The lifting drive member includes a wire cup cover body, a lifting drum and a dial. The wire cup cover body is fixed on the wire wheel body and there is an adjustment gap between the wire cup cover body and the wire wheel body. The lifting drum is located in the adjustment gap. The lower end of the lifting drum is rotatably connected to the rotating shaft fixed on the wire cup cover body. The upper end of the lifting drum passes through the wire wheel body and is fixedly connected to the dial. A spiral groove body is provided on the outer side of the lifting drum. Two side-by-side slide rods are formed on the top of the cylindrical magnetic seat. The slide rods pass through the wire cup cover body upward, and a slider that matches the spiral groove body is formed on one of the slide rods. By turning the lifting knob, the slider moves up and down along the spiral groove body on the outer side of the lifting knob, thereby driving the cylindrical magnetic seat to rise and fall. When the cylindrical magnetic seat descends, the area of ​​the wire cup and the conductive plate cutting the magnetic flux lines increases, thereby improving the braking effect of the brake mechanism. On the contrary, the braking effect is weakened, so that the braking force of the rotating wire cup can be adjusted as needed.

[0009] A centrifugal assembly and an elastic member are provided at the bottom of the cylindrical magnetic seat. The arc-shaped mounting plate is movably mounted on the cylindrical magnetic seat via the centrifugal assembly so as to move toward the inner wall of the wire cup under the action of centrifugation. The arc-shaped mounting plate is connected to the cylindrical magnetic seat via the elastic member so as to be reset in the opposite direction under the elastic force of the elastic member.

[0010] The centrifugal assembly includes an articulated seat, a limit seat and a cover plate. The cover plate is fixed to the bottom of the cylindrical magnetic base via a mounting column. The articulated seat and the limit seat are two groups, which are rotationally symmetrically mounted at the bottom of the cylindrical magnetic base. The limit seat and the corresponding cover plate are provided with strip holes. The two sides of one end of the arc-shaped mounting plate are hinged to the intersection seat and the cover plate via a hinge shaft, and the two sides of the other end of the arc-shaped mounting plate slide in cooperation with the strip holes via the limit posts. By setting the centrifugal assembly, when the entire fishing reel is casting, the spool rotates at high speed, the arc-shaped mounting plate moves radially close to the inner wall of the spool, and the strength of the magnetic lines of force that can be cut by the inner wall of the spool is enhanced, thereby providing greater braking force. At the end of the casting, the rotation speed of the spool gradually decreases, and the arc-shaped mounting plate is driven to reset and move away from the inner wall of the spool under the action of the elastic member, thereby reducing the braking force and realizing self-adjustment of the brake mechanism.

[0011] The elastic member is a torsion spring, which is sleeved on the limiting column between the arc-shaped mounting plate and the limiting seat, and the two ends of the torsion spring are respectively fixedly connected to the arc-shaped mounting plate and the limiting seat.

[0012] The elastic member is a spring, a spring baffle is formed on the limit seat, the arc-shaped mounting plate has a limit column, one end of which extends outward to form a swinging portion arranged opposite to the inner side of the spring baffle, a spring fixing column is formed on the swinging portion, one end of the spring is sleeved on the spring fixing column, and the other end of the spring is in contact with the inner side of the spring baffle.

[0013] The cover plate is provided with an arc-shaped opening corresponding to the position of the arc-shaped mounting plate, and the bottom of the arc-shaped mounting plate extends to the bottom of the cover plate to form a boss portion. The design of the boss portion can reduce the distance between the horizontal magnet installed at the bottom of the arc-shaped mounting plate and the conductive plate, thereby further enhancing the magnetic force threshold and ensuring the braking effect.

[0014] The top of the arc-shaped mounting plate is provided with an arc-shaped embedding groove, the outer side of the boss portion is provided with a slot, a first metal plate for adsorbing a vertical magnet is fixed in the arc-shaped embedding groove, and a second metal plate for adsorbing a horizontal magnet is fixed in the slot. The arrangement of the first metal plate and the second metal plate can ensure the stability of the magnet installed on the arc-shaped mounting plate.

[0015] The beneficial effects of the utility model are as follows: by simultaneously arranging a vertical magnet and a horizontal magnet on the magnetic base, the spool and the conductive plate inside the spool cut the magnetic flux lines simultaneously, and the magnetic flux cut in both directions is superimposed, thereby enhancing the overall magnetic force threshold, ensuring the deceleration effect of the brake mechanism on the spool, and at the same time the centrifugal brake automatically adjusts the rotation speed of the spool to ensure the stability of the brake system.

Other embodiments obtained by those skilled in the art without making any creative work should all fall within the protection scope of the utility model.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a double-sided magnetic brake mechanism of a fishing reel, including a reel body 1, a spool 2 and a cylindrical magnetic seat 3. The top of the cylindrical magnetic seat 3 is connected to the reel body 1 via a lifting drive member. The spool 2 is covered on the outside of the cylindrical magnetic seat 3 and is rotatably connected to the reel body 1. A vertical magnet 5 is arranged on the outside of the cylindrical magnetic seat 3, and a horizontal magnet 6 is arranged on the bottom of the cylindrical magnetic seat 3. The spool 2 has a conductive plate 201 for cutting the magnetic flux of the horizontal magnet 6. In this embodiment, the spool 2 is an aluminum alloy conductor, and the conductive plate 201 is integrally formed on the inner side of the spool 2. The spool 2 and the conductive plate 201 respectively and simultaneously cut the magnetic flux of the vertical magnet 5 and the horizontal magnet 6. This bidirectional cutting method increases the magnetic flux generated during the rotation of the spool 2, thereby enhancing the overall magnetic force threshold and ensuring the deceleration effect of the brake mechanism on the spool 2.

[0026] Specifically, Figure 3As shown, the lifting drive member includes a line cup cover body 7, a lifting drum 8 and a dial 9. The line cup cover body 7 is fixed on the reel body 1 and there is an adjustment gap between the line cup cover body 7 and the reel body 1. An upper inner cylinder 702 is formed in the middle of the line cup cover body 7, and a lower inner cylinder 202 is formed in the middle of the conductive plate 201 of the line cup 2. The line cup 2 is sleeved on the spool 203 of the fishing reel through the lower inner cylinder 202. The upper end of the spool 203 of the fishing reel is rotatably connected to the upper inner cylinder 702 through a bearing, so that the line cup 2 and the line reel body are connected. The lifting drum 8 is rotatably connected to the body 1, the lifting drum 8 is located in the adjustment gap, the lower end of the lifting drum 8 is rotatably connected to the rotating shaft 701 fixed on the line cup cover body 7, the upper end of the lifting drum 8 passes through the line wheel body 1 and is fixedly connected to the dial 9, a spiral groove body 801 is provided on the outer side of the lifting drum 8, and two side-by-side slide rods 301 are formed on the top of the cylindrical magnetic seat 3, the slide rods 301 penetrate the line cup cover body 7 upward, and a slider 302 matching the spiral groove body 801 is formed on one of the slide rods 301.

[0027] By turning the lifting knob, the slider 302 is driven to move up and down along the spiral groove 801 outside the lifting knob, thereby driving the cylindrical magnetic seat 3 to move up and down. When the cylindrical magnetic seat 3 descends, the area of ​​the wire cup 2 and the conductive plate 201 cutting the magnetic flux lines increases, thereby improving the braking effect of the brake mechanism. Conversely, the braking effect is weakened, thereby realizing the adjustment of the braking force of the rotating wire cup 2 as needed.

[0028] Two symmetrically arranged arc-shaped mounting plates 4 are installed on the cylindrical magnetic seat 3, and the vertical magnet 5 and the horizontal magnet 6 are embedded and installed on the outer side and the bottom of the arc-shaped mounting plate 4 respectively, wherein the horizontal magnet 6 is a magnet or a plurality of magnets distributed along the circumferential direction of the outer side of the arc-shaped mounting plate 4, and the vertical magnet 5 is a magnet or a plurality of magnets distributed along the circumferential direction of the bottom of the arc-shaped mounting plate 4. When the horizontal magnet 6 and the vertical magnet 5 are both single magnets, the magnet has an arc adapted to the arc-shaped mounting plate 4, and the horizontal magnet 6 and the vertical magnet 5 can adopt different poles to form a magnetic field from the horizontal magnet 6 to the vertical magnet 5. lines of induction; when the horizontal magnet 6 and the vertical magnet 5 are both multiple magnets, the N pole and the S pole can be arranged alternately to form wavy magnetic lines of induction of the horizontal magnet 6 and the vertical magnet 5 respectively; when the horizontal magnet 6 is a single magnet and the vertical magnet 5 is a plurality of magnets or the horizontal magnet 6 is a plurality of magnets and the vertical magnet 5 is a single magnet, magnetic lines of induction in the direction from the horizontal magnet 6 to the vertical magnet 5 or independent magnetic lines of induction on the horizontal magnet 6 and the vertical magnet 5 are formed. The above arrangement is not unique, and the magnetic lines of induction that can be cut by the wire cup 2 and the conductive plate 201 on the vertical magnet 5 and the horizontal magnet 6 are all within the protection scope of this scheme.

[0029] Furthermore, in order to realize the self-adjusting braking function of the brake mechanism, a centrifugal assembly and an elastic member are provided at the bottom of the cylindrical magnetic seat 3, and the arc-shaped mounting plate 4 is movably mounted on the cylindrical magnetic seat 3 through the centrifugal assembly to move toward the inner wall of the wire cup 2 under the action of the centrifuge, and the arc-shaped mounting plate 4 is connected to the cylindrical magnetic seat 3 through the elastic member to be reversed and reset under the elastic force of the elastic member; specifically, in Example 1, as Figure 4 , Figure 5 and Figure 6 As shown, the centrifugal assembly includes an articulated seat 304, a limiting seat 305 and a cover plate 10. The cover plate 10 is fixed to the bottom of the cylindrical magnetic base via a mounting column 303. Specifically, there are two mounting columns 303, which are symmetrically distributed on both sides of the bottom of the cylindrical magnetic base and one end is formed on the cylindrical magnetic base. The cover plate 10 is fixed to the mounting columns 303 by bolts; the articulated seat 304 and the limiting seat 305 are two groups, which are rotationally symmetrically formed at the bottom of the cylindrical magnetic base 3. A strip hole 1002 is provided on the position of the limit seat 305 and the corresponding cover plate 10, and the two sides of one end of the arc-shaped mounting plate 4 are hinged to the intersection seat and the cover plate 10 via a hinge shaft 401, and the two sides of the other end of the arc-shaped mounting plate 4 slide in cooperation with the strip hole 1002 via a limit column 402. The elastic member is a torsion spring 13, and the torsion spring 13 is sleeved on the limit column 402 between the arc-shaped mounting plate 4 and the limit seat 305, and the two ends are fixedly connected to the arc-shaped mounting plate 4 and the limit seat 305 respectively. By setting up a centrifugal component, when the entire fishing reel is casting, the spool 2 rotates at high speed, and the arc-shaped mounting plate 4 moves along the path of the strip hole 1002 close to the inner wall of the spool 2 under the action of the centrifuge. The strength of the magnetic lines of force that can be cut by the inner wall of the spool 2 is enhanced, thereby providing a greater braking force. At the end of the casting, the rotation speed of the spool 2 gradually decreases, and the arc-shaped mounting plate 4 is driven to reset and move away from the inner wall of the spool 2 under the action of the torsion spring 13, thereby reducing the braking force and realizing self-adjustment of the brake mechanism.

[0030] Furthermore, the cover plate 10 is provided with an arc-shaped opening 1001 corresponding to the position of the arc-shaped mounting plate 4, and the bottom of the arc-shaped mounting plate 4 extends to the bottom of the cover plate 10 to form a boss portion 403. The design of the boss portion 403 can reduce the distance between the horizontal magnet 6 installed at the bottom of the arc-shaped mounting plate 4 and the conductive plate 201, thereby further enhancing the magnetic force threshold and ensuring the braking effect.

[0031] In order to ensure the stability of the installation of the magnet on the arc-shaped mounting plate 4, an arc-shaped embedding groove 404 is provided on the top of the arc-shaped mounting plate 4, and a slot 405 is provided on the outer side of the boss portion 403. A first metal plate 11 for adsorbing the vertical magnet 5 is fixed in the arc-shaped embedding groove 404, and a second metal plate 12 for adsorbing the horizontal magnet 6 is fixed in the slot 405. The first metal plate 11 and the second metal plate 12 are preferably iron metal plates.

[0032] like Figure 7 As shown, the difference between Example 2 and Example 1 is that the elastic member is a spring 14, a spring baffle 3051 is formed on the limit seat 305, the arc-shaped mounting plate 4 has a limit column 402, one end of which extends outward to form a swinging portion 406 arranged opposite to the inner side of the spring baffle 3051, and a spring fixing column 407 is formed on the swinging portion 406. One end of the spring 14 is sleeved on the spring fixing column 407, and the other end of the spring 14 contacts the inner side of the spring baffle 3051. Under the centrifugal effect, the arc-shaped mounting plate 4 approaches the inner wall of the line cup 2, at which time the swinging portion 406 is driven to approach the spring baffle 3051, and the spring 14 between the swinging portion 406 and the spring baffle 3051 is compressed. At the end of the casting, the rotation speed of the line cup 2 is reduced due to the action of the magnetic brake, and the swinging portion 406 is reset under the action of the spring 14, thereby driving the arc-shaped mounting plate 4 away from the inner wall of the line cup 2, thereby reducing the braking force and realizing the self-adjustment of the brake mechanism.

[0033] Taking Example 1 as an example, when implementing the technical solution, the fishing reel is assembled, and according to the actual braking force required, the dial 9 is rotated to drive the cylindrical magnetic seat 3 to rise and fall. Since the vertical magnet 5 and the horizontal magnet 6 are respectively installed on the outside and the bottom of the arc-shaped mounting plate 4 on the cylindrical magnetic seat 3, compared with the traditional brake mechanism with only the vertical magnet 5, the magnetic lines of force cut by the spool 2 during rotation increase, and the threshold of the magnetic force generated by it is enhanced, thereby ensuring the deceleration effect of the brake mechanism on the spool 2; at the same time, due to the setting of the centrifugal component, the brake mechanism can self-adjust the brake under the centrifugal action and the elastic action of the torsion spring 13 when casting the rod, and the overall controllability is improved.
