Description

Technical fields:

[0001] This utility model relates to the field of fishing tackle accessory manufacturing technology, specifically to an embedded automatic adjustment brake device and fishing reel with reasonable structure and easy operation. Background technology:

[0002] Fishing reels are mounted on fishing rods. By cranking the handle, the fishing line is wound onto or unwound from the spool. When letting out line quickly, if the spool rotates too fast, the line is prone to breaking, tangling, or even snapping. Therefore, a reel braking mechanism is needed to adjust the spool rotation speed during the letting-out process. Current reel braking mechanisms include traditional clutch-type braking mechanisms and magnetic braking mechanisms as described in patent documents CN215531024U and WO2022058984A1. In existing magnetic braking mechanisms, the braking force is adjusted by changing the distance between the support component (equipped with a magnetic brake magnet) and the spool. In the aforementioned two documents, the support component or magnetic component moves closer to or further away from the spool along its central axis during braking force adjustment. This type of solution occupies a large amount of internal space, which is not conducive to reducing the product's size and weight. Furthermore, during prolonged fishing, especially competitive fishing, the heavy or bulky components can cause fatigue. Summary of the Invention:

[0003] This utility model addresses the shortcomings and deficiencies of existing technologies by proposing an embedded automatic adjusting brake device and fishing reel with a reasonable structure and simple operation.

[0004] This utility model achieves its purpose through the following measures:

[0005] An embedded automatic adjusting brake device includes a spool and a spool bracket. The spool is mounted on the spool bracket via a rotating shaft, and the spool bracket also has a side cover. The device is characterized by further including a magnetic component. The magnetic component includes a support sleeve coaxially arranged with the spool. One end of the support sleeve is connected to the side cover, and the outer wall of the other end of the support sleeve has a magnet fixing hole. The outer diameter of the support sleeve is smaller than the inner diameter of the spool drum. The end of the support sleeve extends into the spool drum. The magnet is slidably mounted in the magnet fixing hole via an elastic component. When the spool rotates, it cuts the magnetic field lines around the magnet, causing the magnet to extend out along the magnet fixing hole, thus reducing the gap between the magnet and the spool.

[0006] The elastic component of this invention is a spring. The rear end of the magnet is tightened into the magnet fixing hole by the spring, so that when the spool stops rotating, the front end of the magnet is retracted into the magnet fixing hole on the support sleeve under the reset action of the spring.

[0007] The magnet fixing hole of this utility model is channel-shaped and arranged radially along the cross-section of the support sleeve, thereby ensuring that the magnet can be smoothly pulled out radially along the cross-section of the support sleeve under the action of magnetic force, and the channel-shaped magnet fixing hole can provide sufficient space for the installation of the spring component.

[0008] To improve the magnetic stopping effect, the magnet is fixed in the initial position of the magnet fixing hole by a spring, and the end of the magnet is flush with the outer wall of the support sleeve. Furthermore, the outer wall of the support sleeve is provided with two or more magnet fixing holes, and two or more magnets and springs are respectively provided corresponding to the magnet fixing holes. The two or more magnet fixing holes are arranged in a centrally symmetrical manner, preferably 3-8, to provide sufficient braking force for stopping the spool.

[0009] The outer wall of the support sleeve of this utility model is also provided with a magnet positioning hole, and a fixed magnet is embedded and fixed in the magnet positioning hole. The surface of the magnet is flush with the outer wall of the support sleeve, which is used to help improve the braking effect.

[0010] The outer wall of the support sleeve of this utility model has 4-8 magnet positioning holes arranged at equal intervals, and 4-8 fixed magnets are embedded accordingly.

[0011] This utility model also proposes a fishing reel, characterized in that it is equipped with an embedded automatic adjustment brake device as described above.

[0012] In operation, the magnetic component with a support sleeve is installed on the side cover of the spool support frame. The support sleeve is coaxial with the spool but does not rotate. One end of the support sleeve is embedded in the spool's winding drum and contains a magnet. Since the spool can be considered a closed metal ring, when it rotates, it cuts the magnetic field lines generated by the magnet. According to Lenz's law, the spool, acting as a closed metal ring, will experience a magnetic force that slows its rotation, thus achieving braking. During this process, under the influence of the magnetic force, the magnet embedded in the support sleeve within the spool's winding drum will approach the spool and be fixed along the channel magnet. When the hole is moved outward, the end of the magnet is pulled out of the support sleeve surface. At this time, the gap between the end of the magnet and the spool decreases. Due to the high magnetic field density and strong magnetic force near the magnetic pole, the magnetic stopping force on the rotating spool will increase significantly, thereby improving the stopping effect. In order to improve the reliability of this device, the support sleeve is also equipped with a fixed magnet embedded in the surface of the support sleeve. It should be noted that the end of the fixed magnet is flush with the outer wall of the support sleeve, while the pullable magnet is significantly pulled out of the outer wall of the support sleeve during use, and can be returned to its original position by the spring after use.

[0013] Compared with the prior art, this utility model has a reasonable structure, reliable operation, and small size. It does not require the assistance of external motors or other devices and can meet the miniaturization requirements of fishing tackle equipment. Attached image description:

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] As attached Figure 1 and attached Figure 3 As shown, this utility model proposes an embedded automatic adjusting brake device, which includes a spool 1 and a spool bracket. The spool 1 is mounted on the spool bracket via a rotating shaft. The spool bracket also has a side cover 2 and a magnetic component. The magnetic component includes a support sleeve 3 coaxially arranged with the spool 1. One end of the support sleeve 3 is connected to the side cover 2, and the outer wall of the other end of the support sleeve 3 has a magnet fixing hole 4. The outer diameter of the support sleeve 3 is smaller than the inner diameter of the spool 1's drum. The end of the support sleeve 3 extends into the drum of the spool 1. A magnet 5 is slidably disposed in the magnet fixing hole 4 via an elastic component. When the spool 1 rotates, it cuts the magnetic field lines around the magnet 5, causing the magnet 5 to extend along the magnet fixing hole 4, thus reducing the gap between the magnet 5 and the spool 1. The elastic component is a spring 6. The rear end of the magnet 5 is retracted into the magnet fixing hole 4 by the spring 6, so that when the spool 1 stops rotating, the front end of the magnet 5 is retracted into the magnet fixing hole 4 on the support sleeve 3 under the reset action of the spring 6.

[0022] In this example, the magnet fixing hole 4 is channel-shaped and is arranged radially along the cross-section of the support sleeve 3, thereby ensuring that the magnet 5 can be smoothly pulled out radially along the cross-section of the support sleeve 3 under the action of magnetic force, and the channel-shaped magnet fixing hole 4 can provide sufficient space for the installation of the spring component.

[0023] To improve the magnetic stopping effect, the magnet 5 is fixed in the initial position of the magnet fixing hole 4 by the spring 6. The end of the magnet 5 is flush with the outer wall of the support sleeve. Furthermore, there are two or more magnet fixing holes 4 on the outer wall of the support sleeve 3, and there are two or more magnets 5 and springs 6 corresponding to the magnet fixing holes 4 respectively. The two or more magnet fixing holes 4 are arranged in a centrally symmetrical manner. In this example, four are set to provide sufficient braking force for the spool to stop.

[0024] In this example, the outer wall of the support sleeve 3 is also provided with a magnet positioning hole 7, and a fixed magnet 8 is embedded and fixed in the magnet positioning hole 7. The surface of the fixed magnet 8 is flush with the outer wall of the support sleeve 3 to help improve the braking effect. In this example, 4-8 magnet positioning holes are equally spaced around the outer wall of the support sleeve 3, and 4-8 fixed magnets are embedded accordingly.

[0025] This example also proposes a fishing reel equipped with an embedded automatic adjusting brake device as described above.

[0026] During operation, the magnetic component with support sleeve 3 is installed on the side cover 2 of the spool support frame. The support sleeve 3 is coaxial with the spool 1 but does not rotate. One end of the support sleeve 3 is embedded in the spool 1 and is equipped with a magnet 5. Since the spool 3 can be regarded as a closed metal ring, when the spool 1 rotates, it cuts the magnetic field lines generated by the magnet 5. According to Lenz's law, the spool 1, which acts as a closed metal ring, will be subjected to magnetic force and its rotation speed will be reduced, thereby achieving the purpose of braking. During this process, under the action of magnetic force, the magnet 5 embedded in the support sleeve 3 in the spool 1 will approach the spool and move outward along the channel magnet fixing hole 4. That is, the end of the magnet 5 will be pulled out of the surface of the support sleeve 3. At this time, the gap between the end of the magnet 5 and the spool 1 is reduced. Since the magnetic field line density is large and the magnetic force is strong near the magnetic pole, the magnetic stopping force for the rotating spool 1 will be significantly increased, thereby improving the stopping effect.

[0027] To improve the reliability of this device, the support sleeve 3 is also provided with a fixed magnet 8 embedded in the surface of the support sleeve. It should be noted that the end of the fixed magnet 8 is flush with the outer wall of the support sleeve 3, while the pullable magnet 5 is significantly pulled out of the outer wall of the support sleeve 3 during use, and can be returned to its original position by the spring 6 after use.

[0028] Compared with the prior art, this utility model has a reasonable structure, reliable operation, and small size. It does not require the assistance of external motors or other devices and can meet the miniaturization requirements of fishing tackle equipment.
