Description

Technical Field

[0001] This utility model relates to the field of fishing reel technology, and in particular to a magnetic braking mechanism for fishing reels. 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] In existing magnetic braking mechanisms, the brake magnets are mostly mounted vertically on magnet mounting bases. Driven by a lifting mechanism, the magnet mounting base moves in and out of the spool cavity, thereby changing the number of magnetic lines of force (magnetic force) acting on the spool and adjusting the braking force. However, in this traditional magnetic braking mechanism, the brake magnet's mounting position is fixed, and the magnetic force can only be changed by adjusting its axial height. This limits the maximum and minimum number of magnetic lines of force acting on the spool, thus restricting the overall range of magnetic force adjustment and limiting the deceleration effect. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention provides a magnetic braking mechanism for fishing reels, which has a wider range of magnetic force adjustment to achieve better deceleration.

[0005] The technical solution of this utility model is as follows: a magnetic braking mechanism for fishing reels, including a mounting base, magnetic seats, and an adjusting disc. The top of the mounting base has a driving part that cooperates with a lifting drive component to drive the mounting base axially. The mounting base has multiple radial grooves along its circumference. The number of magnetic seats is the same as the number of radial grooves, and each magnetic seat slides in cooperation with each radial groove. A brake magnet is fixed to the outer end of each magnetic seat, and the inner end of each magnetic seat is connected to the mounting base via an elastic element. The adjusting disc is rotatably disposed at the bottom of the mounting base. The outer side of the adjusting disc has an adjusting part. The adjusting part is configured to drive each magnetic seat to move away from the center of the mounting base when the adjusting disc rotates in a first direction. The elastic element is configured to drive each magnetic seat to reverse and reset when the adjusting disc rotates in a second direction. By rotating the adjusting disc in the first direction, the magnetic base moves outward, causing the brake magnet on the outer side of the magnetic base to move radially closer to the spool, thereby increasing the initial number of magnetic lines acting on the spool. By rotating the adjusting disc in the second direction, the elastic element causes the magnetic base to move inward, causing the brake magnet on the outer side of the magnetic base to move radially away from the spool, thereby reducing the initial number of magnetic lines acting on the spool. This changes the initial magnetic force value of the braking mechanism when the mounting base is in its initial position. With the axial adjustment of the lifting drive component, a wider range of magnetic force adjustment is obtained, thus achieving a better deceleration effect according to the user's needs.

[0006] The adjustment part is a curved surface structure formed on the outside of the adjustment plate. The distance between the outer edge of the curved surface structure and the center of the mounting cylinder gradually increases along the second direction. The bottom of the magnetic base has a boss that mates with the curved surface structure.

[0007] The outer edge of the adjustment disc has a raised gear seat, the gear seat has multiple gear slots along the circumference, and the mounting cylinder has a latch plate that elastically contacts the gear seat, the latch plate has a positioning tip that cooperates with the gear slot.

[0008] The gear slots include a low gear slot on one side of the gear seat, a high gear slot on the other side of the gear seat, and a medium gear slot in the middle of the gear seat. The low gear slot and the high gear slot are chamfered surfaces that cooperate with the inclined side of the positioning tip. A limiting post is fixed at the bottom of the mounting cylinder. The adjusting plate is provided with a limiting groove for the circumferential movement of the limiting post, and the limiting groove has a limiting path that matches the path required for the positioning tip to move from the low gear slot to the high gear slot.

[0009] The bottom of the mounting base extends into a bushing portion, and the adjusting disc is sleeved on the outside of the bushing portion through a through hole portion. The lower end of the bushing portion is formed with multiple baffle portions along the circumferential direction. The through hole portion is provided with multiple notches for each of the baffle portions to pass through. There is a rotation gap between the baffle portions and the bottom of the mounting base for the adjusting disc to rotate.

[0010] The elastic element is a compression spring. The bottom of the radial groove has a spring mounting cavity. The inner end of the magnetic base has a spring seat that fits into the spring mounting cavity. One end of the compression spring is connected to the spring seat, and the other end is set away from the center of the mounting cylinder and connected to the inner wall of the spring mounting cavity.

[0011] The radial groove has limiting baffles on both sides, and there is a slide between the limiting baffles and the bottom of the radial groove. The magnetic base has sliding parts on both sides that cooperate with the slide. Each sliding part includes a front sliding part and a rear sliding part that are spaced apart. The limiting baffle has an inlet for the rear sliding part to pass through.

[0012] The limiting baffle has a stepped portion at a position away from the center of the mounting base, and the magnetic base has a limiting protrusion. The limiting protrusion cooperates with the stepped portion to limit the maximum distance the magnetic base can move away from the center of the mounting base.

[0013] The limiting baffle has a guide surface on the side facing away from the step, and the limiting protrusion has a deformable deformation that can enter the step along the guide surface under the action of external force.

[0014] The device includes a sound-generating pin and a top pin spring. A pin groove is provided on the mounting cylinder between any two adjacent radial slides. The top pin spring is located in the pin groove. One end of the sound-generating pin is inserted into the top pin spring. The middle part of the sound-generating pin has a limiting ring portion that abuts against the top pin spring. The other end of the top pin is in contact with the sound-generating groove formed on the surface of the adjustment plate.

[0015] The beneficial effects of this utility model are as follows: This solution rotates the adjusting disc along the first direction, causing the magnetic base to move outward, so that the brake magnet on the outside of the magnetic base moves radially closer to the spool, thereby increasing the initial number of magnetic lines acting on the spool. Rotating the adjusting disc along the second direction causes the elastic element to move the magnetic base inward, so that the brake magnet moves radially away from the spool, thereby reducing the initial number of magnetic lines acting on the spool. This changes the initial magnetic force value of the braking mechanism when the mounting base is in its initial position. With the axial adjustment of the lifting drive component, a wider range of magnetic force adjustment is obtained, thereby achieving a better deceleration effect according to the user's needs.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative effort should all fall within the protection scope of this utility model.

[0019] like Figures 1-3 As shown, this utility model provides a magnetic braking mechanism for fishing reels, which is installed between the reel body 200 and the spool 400. It includes a mounting base 1, a magnetic base 2, and an adjusting disc 3. The top of the mounting base 1 has a driving part that cooperates with a lifting drive component 300 to drive the mounting base 1 axially. In this solution, the lifting drive component 300 adopts an existing structure, such as in our company's publication number CN222170988U, where the lifting drive component 300 includes a spool 400 cover, a lifting cylinder, and a dial. Figure 3 As shown, the driving unit consists of two parallel sliding rods 5 formed on the mounting base 1. The two sliding rods 5 extend upwards through the cap of the spool 400. One of the sliding rods 5 has a slider 501 formed on it. This slider 501 engages with the spiral groove on the outside of the lifting rotating cylinder. The dial drives the lifting rotating cylinder to rotate, and the slider 501 slides along the spiral groove, thereby driving the mounting base 1 to rise and fall. More preferably, as... Figure 4As shown, the mounting base 1 has multiple radial grooves 101 along its circumference. The number of magnetic seats 2 is the same as the number of radial grooves 101, and each magnetic seat 2 corresponds to and slides with each radial groove 101. A brake magnet 4 is fixed to the outer end of each magnetic seat 2, and the inner end of each magnetic seat 2 is connected to the mounting base 1 via an elastic element. The adjusting disk 3 is rotatably disposed at the bottom of the mounting base 1. The adjusting disk 3 has an adjusting part on its outer side. The adjusting part is configured to drive each magnetic seat 2 to move away from the center of the mounting base 1 when the adjusting disk 3 rotates in a first direction. The elastic element is configured to drive each magnetic seat 2 to reverse and reset when the adjusting disk 3 rotates in a second direction.

[0020] Specifically, in this solution, such as Figure 4 As shown, there are five radial grooves 101, evenly spaced on the lower surface of the mounting base 1. Each magnetic seat 2 has two brake magnets 4, resulting in ten brake magnets 4 arranged around the axis of the mounting base 1. The magnetic lines of force generated by the brake magnets 4 are cut by the outer spool 400, which rotates relative to the reel body 200. Figure 1 As shown, the first direction in this scheme is the counterclockwise direction on the adjustment disk 3, opposite to the direction indicated by the arrow, while the second direction is the clockwise direction indicated by the arrow. By rotating the adjustment disk 3 counterclockwise, the adjustment part drives the magnetic base 2 to move outward, so that the brake magnet 4 on the outside of the magnetic base 2 moves radially closer to the spool 400, thereby increasing the initial number of magnetic lines acting on the spool 400. By rotating the adjustment disk 3 clockwise, the elastic element drives the magnetic base 2 to move inward, so that the brake magnet 4 on the outside of the magnetic base 2 moves radially away from the spool 400, thereby reducing the initial number of magnetic lines acting on the spool 400. This changes the initial magnetic force value of the braking mechanism 100 in the initial position of the mounting cylinder 1. Under the axial adjustment of the lifting drive 300, a wider range of magnetic force adjustment is obtained, thereby obtaining a better deceleration effect according to the user's needs.

[0021] like Figure 6 As shown, the adjusting part is a curved surface structure 303 formed on the outer side of the adjusting disc 3. The distance between the outer edge of the curved surface structure 303 and the center of the mounting base 1 gradually increases along the second direction, such as... Figure 5 As shown in (a), the bottom of the magnetic base 2 has a boss 201 that engages with the curved surface structure 303.

[0022] like Figure 2 , Figure 4 and Figure 5As shown in (b), the elastic element is a compression spring 6. The bottom of the radial groove 101 is provided with a spring mounting cavity 107. The inner end of the magnetic base 2 has a spring seat 206 that fits into the spring mounting cavity 107. One end of the compression spring 6 is connected to the spring seat 206, and the other end is set away from the center of the mounting cylinder 1 and connected to the inner wall of the spring mounting cavity 107. Preferably, a first spring post 108 is formed on the inner wall of the spring mounting cavity 107, and a second spring post 207 is formed on the spring seat 206. The two ends of the compression spring 6 are respectively sleeved on the first spring post 108 and the second spring post 207 to complete the connection of the compression spring 6.

[0023] Further preferably, in order to achieve the gear limitation after adjustment by the adjustment dial 3, such as Figure 6 As shown, the outer edge of the adjusting disc 3 has a raised gear seat 304, and the gear seat 304 has multiple gear slots along the circumference, such as... Figure 4 As shown, the mounting base 1 has a latch plate 109 that elastically contacts the gear position seat 304, and the latch plate 109 has a positioning tip 1091 that mates with the gear position groove. Preferably, as shown... Figure 4 and Figure 7 As shown, a U-shaped or V-shaped opening groove is provided on the mounting cylinder 1 between two adjacent radial sliding grooves 101, facing away from the center. The latch plate 109 is formed in any of the opening grooves, arc-shaped and surrounding the outside of the gear position seat 304. It has a certain elasticity and can move away from the gear position seat 304 under the action of external force, and reset under its own elasticity. After the positioning tip 1091 cooperates with the gear position groove, the latch plate 109 is in the reset state. As the adjusting disk 3 is rotated, the positioning tip 1091 disengages from the gear position groove, and is squeezed by the outer edge of the gear position seat 304. The latch plate 109 undergoes elastic deformation until the positioning tip 1091 enters the next gear position groove, and the latch plate 109 elastically resets.

[0024] like Figure 6 and Figure 7 As shown, in this scheme, the gear slots include a low gear slot 3041 located on one side of the gear seat 304, a high gear slot 3043 located on the other side of the gear seat 304, and a middle gear slot 3042 located in the middle of the gear seat 304. More preferably, the low gear slot 3041 and the high gear slot 3043 are chamfered bevels that mate with the inclined side of the positioning tip 1091. A limiting post 10 is fixed to the bottom of the mounting cylinder 1. The adjusting plate 3 is provided with a limiting groove 305 for the circumferential movement of the limiting post 10, and the limiting groove 305 has a limiting path adapted to the path required for the positioning tip 1091 to move from the low gear slot 3041 to the high gear slot 3043, i.e., as shown... Figure 9As shown in (b), when the adjusting disc 3 rotates to the point where the positioning tip 1091 contacts the chamfered surface of the low gear slot 3043, the limiting post 10 contacts the front side of the slot wall in the limiting slot 305 in the first direction. Due to the restriction of the slot wall of the limiting slot 305, the adjusting disc 3 cannot rotate in the second direction. At this time, the boss 201 of the magnetic base 2 contacts the point closest to the center on the curved structure 303. At this time, the gear is the lowest gear (first gear). Figure 9 As shown in (d), when the adjusting disc 3 rotates until the positioning tip 1091 moves out of the gear seat 304 and contacts the chamfered surface of the high gear groove 3043, the limiting post 10 contacts the groove wall of the limiting groove 305 located on the rear side in the first direction. Due to the restriction of the groove wall of the limiting groove 305, the adjusting disc 3 can no longer rotate in the first direction. At this time, the boss part 201 of the magnetic seat 2 contacts the point farthest from the center on the curved structure 303. At this time, the gear is the highest gear (third gear). The middle gear groove is an arc-shaped groove located on the outer edge surface of the gear seat 304. The number of such arc-shaped grooves is at least one, and can be set according to the number of gears to be adjusted. In this scheme, the number is one. When the arc-shaped groove is engaged with the positioning tip 1091, the gear is the second gear.

[0025] To facilitate the installation of the adjustment disc 3, such as Figure 4 As shown, the bottom of the mounting base 1 extends a bushing portion 102, which is sleeved on the outside of the rotating shaft 500 of the reel body 200. The adjusting disc 3 is sleeved on the outside of the bushing portion 102 through the through hole portion 301. Preferably, the lower end of the bushing portion 102 is formed with a plurality of baffle portions 103 in the circumferential direction. The through hole portion 301 is provided with a plurality of notches 302 for each of the baffle portions 103 to pass through. There is a rotation gap 1021 between the baffle portion 103 and the bottom of the mounting base 1 for the adjusting disc 3 to rotate. Figure 9 As shown in (a), when each notch 302 corresponds to each baffle 103, the adjusting plate 3 is in the initial installation position. In order to avoid interference between the limiting post 10 and the adjusting plate 3, the limiting post 10 and the mounting cylinder 1 are connected in a detachable manner. Specifically, the limiting post 10 is a threaded cylinder, and a threaded groove 111 that is threaded to the threaded cylinder is provided on the mounting cylinder 1. Each magnetic seat 2 is moved outward along the radial sliding groove 101 until the boss 201 moves to the outside of the adjusting plate 3 and contacts the outer edge surface of the adjusting plate 3. At this time, it is rotated in the first direction, the notch 302 and the baffle 103 are misaligned, and the boss 201 slides along the outer edge surface of the adjusting plate 3 to the curved structure 303.

[0026] Furthermore, to better identify the gear position when rotating the adjustment dial, such as Figure 3 and Figure 4As shown, the brake mechanism 100 also includes a sound-emitting pin 8 and a top pin spring 7. A pin groove 109 is provided on the mounting sleeve 1 between any two adjacent radial slide grooves 101. The top pin spring 7 is located within the pin groove 109. One end of the sound-emitting pin 8 is inserted into the top pin spring 7. The middle part of the top pin 8 has a limiting ring portion 801 that abuts against the top pin spring 7. The other end of the top pin 8 cooperates with a sound-emitting groove 305 formed on the surface of the adjusting disc 3. Preferably, the number of sound-emitting grooves 305 is the same as the number of gear slots on the gear position seat 304. In this design, since there are three gear slots, the number of sound-emitting grooves is... Correspondingly, the sound-generating grooves 305 along the first direction are respectively referred to as the low-position sound-generating groove, the middle-position sound-generating groove, and the high-position sound-generating groove. That is, when the positioning tip 1091 is engaged with the low-position groove 3041, the sound-generating pin 8 is located in the low-position sound-generating groove; when the positioning tip 1091 is engaged with the middle-position groove 3042, the sound-generating pin 8 is located in the middle-position sound-generating groove; and when the positioning tip 1091 is engaged with the high-position groove 3043, the sound-generating pin 8 is located in the high-position sound-generating groove. Furthermore, under the elastic force of the top pin spring 7, the sound-generating pin 8 can exert downward pressure on the adjusting plate 3, thereby making the adjusting plate 3 stably set at the bottom of the mounting base 1.

[0027] Further preferably, to facilitate the rotation of the adjusting disc 3, such as Figure 6 As shown, a lever 307 is also formed at the bottom of the adjustment disc 3, and the lever 307 can be formed on the outside of the notch 302.

[0028] like Figure 4 As shown, the radial groove 101 has limiting baffles 104 on both sides, and a sliding track 105 is provided between the limiting baffles 104 and the bottom of the radial groove 101, as shown. Figure 5 As shown in (a), the magnetic base 2 has sliding portions on both sides that cooperate with the slide rail 105. Each sliding portion includes a front sliding portion 203 and a rear sliding portion 204 spaced apart. The front sliding portion 203 is located near the outer side of the magnetic base 2, and the rear sliding portion 204 is located near the inner side of the magnetic base 2. The limiting baffle 104 has an inlet 106 for the rear sliding portion 204 to pass through. Of course, the limiting baffle 104 is divided into a front baffle 104a and a rear baffle 104b by the inlet 106. The front baffle 104a is located near the outer side of the mounting cylinder 1, and the rear baffle 104a is located near the outer side of the mounting cylinder 1. 104b is disposed near the inner side of the mounting cylinder 1. The front baffle 104a can pass through the gap between the front sliding part 203 and the rear sliding part 204. When the magnetic base 2 is installed, the spring seat 206 of the magnetic base 2 corresponds to the spring mounting cavity 107 on the radial slide groove 101, the rear sliding part 204 corresponds to the insertion port 106, and the front baffle 104a corresponds to the gap. The magnetic base 2 enters the radial slide groove 101 and slides close to the center of the mounting cylinder 1, thereby increasing the distance between the first spring post 108 and the second spring post 207, so as to install the compression spring 6.

[0029] Further preferred, such as Figure 8 As shown, the limiting baffle 104 has a stepped portion 104c at a position away from the center of the mounting base 1, that is, the inner side of the front baffle 104a has a stepped portion 104c. The magnetic base 2 has a limiting protrusion 205, which cooperates with the stepped portion 104c to limit the maximum distance the magnetic base 2 can move away from the center of the mounting base 1. Figure 8 As shown, when the positioning tip 202 engages with the high-position groove 3043, the magnetic base 2 moves outward to the position where the limiting protrusion 205 contacts the inner side of the step portion 104c. Under the resistance of the step portion 104c, the limiting protrusion 20 forms a space that restricts the outward movement of the magnetic base 2, thus preventing the front sliding portion 203 from disengaging from the slide rail 105 due to the continuous outward movement of the magnetic base 2 under the centrifugal force of the casting rod.

[0030] Further preferably, to facilitate the assembly of the magnetic base 2 with the limiting protrusion 205, the limiting baffle 104 has a guide surface 104d on the side facing away from the step portion 104c. The limiting protrusion 205 has a deformable deformation that allows it to enter the step portion 104c along the guide surface 104d under the action of external force. Specifically, the entire magnetic base 2 can be injection molded from plastic resin, and the limiting protrusion 205 formed after injection molding has a certain degree of variable elasticity. In this solution, such as... Figure 5 As shown in (a), the limiting protrusion 205 is located above the front sliding part 203. After the magnetic seat 2 is inserted into the radial groove 101, the limiting protrusion 205 and the front sliding part 203 are located on the outside of the front baffle 104a. Under the action of external force, the limiting protrusion 205 is squeezed along the guide surface 104d to reach the inside of the front baffle 104a and forms a limiting fit with the step part 104c.

[0031] When using this brake mechanism 100, the mounting cylinder 1 with the magnetic base 2 is assembled at the bottom of the wheel body 200, such as... Figure 9 As shown in (a), the adjusting disc 3 is fastened to the bottom of the mounting base 1, with its notch 302 corresponding one-to-one with the baffle 103. Each magnetic base 2 is moved outwards so that the protrusion 201 of each magnetic base 2 is located outside the adjusting disc 3 and contacts the outer edge of the adjusting disc 3. The adjusting disc 3 is rotated counterclockwise (in the opposite direction of the arrow). Figure 9 As shown in (b), the low gear groove 3041 of the gear position seat 304 contacts the inclined side of the positioning tip 1091 of the latch plate 109, and the limiting post 10 is assembled into the threaded groove 111 of the mounting sleeve seat 1 through the limiting groove 305, forming a rotational limit after assembly. At this time, the initial magnetic force generated by the brake mechanism 100 on the spool 400 is the first gear, such as... Figure 9As shown in (c), the middle gear slot 3042 of the gear position seat 304 engages with the positioning tip 1901. At this time, the initial magnetic force generated by the brake mechanism 100 on the spool 400 is the second gear. Figure 9 As shown in (d), the high-position groove 3043 of the gear seat 304 contacts the oblique side of the positioning tip 1091. At this time, the initial magnetic force generated by the brake mechanism 100 on the spool 400 is three gears. The magnetic force of the first gear is greater than that of the second gear, which is greater than that of the third gear. The fishing reel user selects the gear according to his / her needs. With the cooperation of the lifting drive component 300, a wider range of magnetic force adjustment is obtained, resulting in a better deceleration effect.
