Description

Technical Field

[0001] This invention relates to the field of fishing rod technology, and in particular to an internal line routing structure for a fishing rod. Background Technology

[0002] Internally routed fishing rods, as a new type of fishing tool, reduce the impact of external obstacles on the fishing line by using internal line routing, thus improving casting accuracy and ease of operation. However, due to the enclosed nature of the internal structure, user operation is somewhat limited when adjusting line tension or braking system resistance, and the adjustment flexibility is not as good as with external structures. This may affect the fishing experience, especially when quick adjustments to line tension are needed, where the flexibility of the internally routed structure is relatively insufficient. Summary of the Invention

[0003] The main objective of this invention is to provide an internal line routing structure for a fishing rod, which aims to precisely control the release speed and tension of the fishing line, reduce internal space occupation, and improve the balance and handling feel of the fishing rod.

[0004] To achieve the above objectives, the present invention proposes an internal line routing structure for a fishing rod, comprising a rod body, an internal line routing channel, a mounting bracket inserted at the tail of the rod body, a drive shaft rotatably connected to the mounting bracket along the axial direction of the rod body, a portion of the drive shaft sleeved with a spool, and the other portion driving a line-pulling structure, the line-pulling structure extending to the outside of the spool and reciprocating along the drive shaft to make the fishing line evenly wound around the spool;

[0005] The mounting bracket is also radially rotatably connected to a rotating shaft, which drives the transmission shaft. One end of the rotating shaft is provided with a rocker handle. A driving bevel gear is connected to the rotating shaft, and a driven bevel gear is connected to the transmission shaft. The driving bevel gear meshes with the driven bevel gear to drive the transmission shaft to rotate. A force-relieving structure is provided on one side of the driving bevel gear.

[0006] In one possible implementation, the stress-relieving structure includes:

[0007] Mounting base, which is sleeved on the rotating shaft and partially has external threads;

[0008] A clamping gear is disposed on the side of the driving bevel gear and screwed to the mounting base;

[0009] A transmission rack is connected to the clamping gear and has an adjustment knob for driving the transmission rack to move along the axial direction of the rod body, so as to drive the clamping gear to approach or separate from the driving bevel gear.

[0010] In one possible implementation, the adjustment knob is screwed to the mounting bracket and extends outward from the tail of the rod, with the transmission rack abutting against the adjustment knob.

[0011] In one possible implementation, a friction plate is provided between the clamping gear and the driving bevel gear.

[0012] In one possible implementation, the dialing structure includes:

[0013] A cable organizer, one end of which is screwed to the drive shaft, and the other end extends to the outside of the spool;

[0014] A guide rod, the two ends of which are connected to the mounting bracket, and the cable organizer is slidably connected to the guide rod.

[0015] In one possible implementation, the outer wall of the rod body is provided with a mounting groove, and the crank handle includes a drive arm and a handhold that are rotatably connected. When the crank handle is in the working state, the handhold rotates relative to the drive arm to form an angle; when the crank handle is in the retracted state, the handhold and the drive arm are located on the same plane.

[0016] In one possible implementation, a locking structure is further provided at the connection between the drive arm and the handheld part, including:

[0017] The locking block has a mounting position at one end of the drive arm, the main body of the locking block is rotatably connected to the mounting position, one end of the locking block is connected to the handheld part, and the other end is provided with multiple limiting grooves.

[0018] A stop block is disposed within the mounting position and abuts against a limiting groove, so that the handheld part and the drive arm form different angles.

[0019] This invention reduces friction and interference between the fishing line and the external guide ring by incorporating a line channel inside the fishing rod. A mounting bracket is inserted at the butt of the rod, and an axial drive shaft is mounted on the bracket. Part of the drive shaft is fitted with a spool for winding the fishing line, while the other half has external threads and drives a line-pulling mechanism. This mechanism extends to the outside of the spool and reciprocates along the drive shaft, ensuring the fishing line is evenly wound around it. A radially mounted rotating shaft is also present on the mounting bracket, connected to the drive shaft. One end of the rotating shaft has a crank for driving its rotation, while the other end has a stress-relieving structure for precise control of the fishing line tension and release. This internal line channel allows for smoother casting, reducing resistance and error, and improving casting accuracy and distance. The line's movement within the rod reduces contact with external objects, making it less prone to friction or tangling with obstacles, branches, rocks, etc., effectively protecting the line and extending its lifespan.

[0020] Furthermore, the unloading structure is completed by the cooperation of the clamping gear and the transmission rack, which can precisely control the tension and release of the fishing line. By adjusting the rotation of the clamping gear, the user can gradually increase or decrease the braking force, so that the fishing line can be released stably when the big fish is struggling, avoiding the loss of the line or fish due to sudden release or excessive tightness.

[0028] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] To address the problems in the background art, the present invention proposes an internal line routing structure for a fishing rod, comprising a rod body 10, wherein a line routing channel is provided inside the rod body 10, and a mounting bracket 20 is inserted into the tail of the rod body 10. A drive shaft 21 is rotatably connected to the mounting bracket 20 along the axial direction of the rod body 10. A portion of the drive shaft 21 is fitted with a spool 211, and the other portion is driven and connected to a line-pulling structure 212. The line-pulling structure 212 extends to the outside of the spool 211 and reciprocates along the drive shaft 21 to make the fishing line evenly wound around the spool 211. A rotating shaft 22 is also radially rotatably connected to the mounting bracket 20, and the rotating shaft 22 is driven and connected to the drive shaft 21. One end of the rotating shaft 22 is provided with a crank handle 221, and the other end is provided with a force-relieving structure 222.

[0031] Combined with reference Figures 1 to 4 As shown, the rod body 10 is the main part of the fishing rod, which can be made of engineering plastics, carbon fiber composite materials, or alloy materials. It is hollow inside to create a line channel, and its inner wall can be lined with abrasion-resistant materials, such as ceramic rings. The fishing line is hidden inside the rod body 10, reducing friction and interference between the fishing line and the external guide rings. Since the external guide rings are no longer needed, casting is smoother, reducing resistance and error during casting, and improving casting accuracy and distance. The fishing line runs inside the rod body with internal line routing, reducing contact with external objects and making it less likely to rub against or tangle with obstacles, branches, rocks, etc., thus effectively protecting the fishing line and extending its lifespan.

[0032] A mounting bracket 20 is inserted at the tail of the rod body 10 to support and fix components such as the drive shaft 21 and the rotating shaft 22. After the mounting bracket 20 is inserted into the inside of the rod body 10, it can be interference-fitted with the inner wall of the rod body 10, plugged in, or fixed by screws through threaded holes on the outer wall. The rotating shaft is rotatably connected to the front part of the mounting bracket 20. The drive shaft 21 has a spool 211 sleeved on the front half of the rod tail for winding the fishing line. The rear half is provided with threads or fish scale patterns and drives the line-pulling structure 212. The other end of the line-pulling structure 212 extends to the outside of the spool 211. The fishing line passes through the end of the line-pulling structure 212 located on the side of the spool 211. When the drive shaft 21 rotates, the line-pulling structure 212 reciprocates along the drive shaft 21, thereby evenly winding the fishing line on the spool 211, ensuring that the fishing line is laid flat and untangled, and can work more reliably during long-term use or when a large fish is pulling the line.

[0033] The mounting bracket 20 also features a radially rotatable shaft 22. One end of the shaft 22 is connected to a handle 221 for driving its rotation, while the other end has a stress-relieving structure 222 for controlling the tension of the fishing line, preventing it from becoming too tight or too loose. This is especially important when dealing with struggling large fish, as the stress-relieving structure 222 helps to release energy from the line and prevent breakage. The middle part of the shaft 22 is connected to a drive shaft 21. The handle drives the shaft 22 to rotate, which in turn drives the drive shaft 21 to rotate, thus enabling the reeling in and unloading of the line.

[0034] In one possible implementation, a driving bevel gear 223 is connected to the rotating shaft 22, and a driven bevel gear 213 is connected to the transmission shaft 21. The driving bevel gear 223 meshes with the driven bevel gear 213 to drive the transmission shaft 21 to rotate. A force-relieving structure 222 is provided on one side of the driving bevel gear 223.

[0035] Combined with reference Figure 3 and Figure 4 As shown, the driving bevel gear 223 is connected to the rotating shaft 22, which is rotatably connected to the mounting bracket 20 along the radial direction of the rod body 10. The rotating shaft 22 provides power for the rotation of the driving bevel gear 223. The driven bevel gear 213 is connected to the transmission shaft 21 and meshes with the driving bevel gear 223. By driving the rotating shaft 22 to rotate, the driving bevel gear 223 can be driven to rotate, thereby driving the transmission shaft 21 to rotate, and further driving the spool 211 to rotate, so as to wind the fishing line onto the spool 211. By setting up the gear set, the direction of the rotational power can be changed, so that the axially positioned spool 211 can rotate. Setting the spool 211 along the axial direction of the rod body 10 can reduce the friction between the spool 211 and the fishing rod, thereby reducing resistance and making the winding smoother; reducing friction means that the wear between the spool 211 and other components will also be reduced, extending the service life of the line winding structure; the axial arrangement helps to maintain the overall balance of the fishing rod and reduce the feeling of imbalance during use.

[0036] In one possible implementation, the stress-relieving structure 222 includes:

[0037] Mounting base 2221, which is sleeved on the rotating shaft 22 and partially has external threads;

[0038] A clamping gear 2222 is disposed on the side of the driving bevel gear 223 and screwed to the mounting base 2221;

[0039] A transmission rack 2223 is connected to the clamping gear 2222. The transmission rack 2223 is connected to an adjustment knob 24 for driving the transmission rack 2223 to move along the axial direction of the rod body 10, so as to drive the clamping gear 2222 to approach or separate from the driving bevel gear 223.

[0040] Combined with reference Figure 4 The mounting base 2221 is roughly stepped and is fitted onto the rotating shaft 22. The smaller diameter portion has external threads, where the clamping gear 2222 is screwed. The transmission rack 2223 meshes with the clamping gear 2222, and an adjustment knob 24 is located at one end of the transmission rack 2223. This knob drives the transmission rack 2223 to reciprocate along the circumference of the rod body 10, thereby rotating the clamping gear 2222. This causes the clamping gear 2222 to engage or disengage from the end face of the driving bevel gear 223. When engaged with the driving bevel gear 223, it increases friction, thus stopping the driving bevel gear 223 from rotating. Conversely, when force needs to be released, the clamping gear 2222 meshes with the transmission rack 2223, converting the rotational motion into linear motion of the transmission rack 2223. That is, by changing the rotation direction of the gear, the rack moves in the opposite direction to counteract the original motion. This method is typically used in situations requiring rapid response.

[0041] In summary, firstly, the rack and pinion structure provides linear and stable force transmission, allowing the drag system to more precisely control the release speed and tension of the fishing line. This high-precision adjustment method is particularly suitable for handling fish of different sizes and strengths, meeting the needs of various fishing scenarios. Secondly, the rack and pinion structure reduces reliance on traditional friction plates (2224), thereby reducing wear and heat attenuation issues. By optimizing the materials and design of the rack and pinion, the durability and reliability of the drag system can be further improved. Thirdly, compared to traditional braking systems, the rack and pinion structure can be more compactly integrated into the fishing rod, reducing the space occupied. This not only helps to reduce the overall weight of the fishing rod but also improves its balance and handling.

[0042] In one possible implementation, the adjustment knob 24 is screwed to the mounting bracket 20 and extends outward from the tail of the rod body 10, and the transmission rack 2223 abuts against the adjustment knob 24.

[0043] Combined with reference Figure 3 and Figure 4 As shown, the adjustment knob 24 can be screwed onto the mounting bracket 20 and extends outward from the tail end of the rod body 10 for easy user operation. One end of the transmission rack 2223 abuts against the adjustment knob 24. Rotating the adjustment knob 24 drives the transmission rack 2223 to reciprocate, thereby driving the clamping gear 2222 to engage or disengage from the driving bevel gear 223. The unloading structure 222 can precisely control the tension of the fishing line by adjusting the pressure of the gear, avoiding the fishing line from being too tight or too loose. Especially when dealing with struggling large fish, the unloading mechanism can adjust the amount of fishing line released in time to avoid line breakage.

[0044] In one possible implementation, a friction plate 2224 is provided between the clamping gear 2222 and the driving bevel gear 223. The friction force adjusts the unloading strength, ensuring a smooth release of the fishing line during braking and avoiding excessive impact. The friction plate 2224 can be a ceramic friction plate 2224, an organic friction plate 2224, or a semi-metallic friction plate 2224.

[0045] In one possible implementation, the dialing structure 212 includes:

[0046] The cable organizer 2121 has one end screwed to the drive shaft 21 and the other end extending to the outside of the spool 211.

[0047] Guide rod 2122, both ends of which are connected to the mounting bracket 20, and cable organizer 2121 is slidably connected to the guide rod 2122.

[0048] Combined with reference Figures 2 to 4 As shown, the line organizer 2121 is roughly L-shaped, with one end screwed to the drive shaft 21 and the other end extending to the outside of the spool 211. A guide rod 2122 can also be installed on the mounting bracket 20. The line organizer 2121 and the guide rod 2122 are slidably connected, serving a guiding function to ensure the linear and stable sliding of the line organizer 2121. A line-passing hole is also provided at the end of the line organizer 2121 near the spool 211, through which the fishing line passes and is wound around the spool 211. Guided by the guide rod 2122, the line organizer 2121 can smoothly reciprocate, making the fishing line evenly and neatly wound on the spool 211, avoiding the problem of overlapping or knotting of the fishing line.

[0049] In one possible implementation, the outer wall of the rod body 10 is provided with a mounting groove 11, and the crank handle 221 includes a drive arm 2211 and a handhold 2212 rotatably connected. When the crank handle 221 is in the working state, the handhold 2212 rotates relative to the drive arm 2211 to form an angle; when the crank handle 221 is in the retracted state, the handhold 2212 and the drive arm 2211 are located on the same plane.

[0050] The handle 221 may include a handheld part 2212 and a drive arm 2211, and the handheld part 2212 may be rotatably connected to the drive arm 2211 so that the handheld part 2212 and the drive arm 2211 present different included angles. When the handheld part 2212 is rotated, the included angle between the handheld part 2212 and the drive arm 2211 can be 180 degrees, and the drive arm 2211 rotates accordingly. The power is transmitted to the transmission shaft 21 through the rotating shaft 22. The rotation of the transmission shaft 21 drives the spool 211 to rotate, realizing the winding or unwinding of the fishing line. When it is necessary to store and carry, the handheld part 2212 rotates to be coplanar with the drive arm 2211, and the included angle between the two is 180 degrees, which reduces the space occupied and makes it easy to carry and store.

[0051] In one possible implementation, a locking structure 2213 is further provided at the connection between the drive arm 2211 and the handheld part 2212, including:

[0052] Locking block 2213a, one end of the drive arm 2211 is provided with a mounting position, the main body of the locking block 2213a is rotatably connected to the mounting position, one end of the locking block 2213a is connected to the hand-held part 2212, and the other end is provided with multiple limiting grooves;

[0053] Stop block 2213b is disposed in the mounting position and abuts against a limiting groove, so that the hand grip 2212 and the drive arm 2211 are at different angles.

[0054] Combined with reference Figure 3 and Figure 4As shown, to ensure that the handle 2212 does not fold accidentally during use, a locking structure 2213 can be provided at the rotatable connection between the drive arm 2211 and the handle 2212. This structure includes a locking block 2213a and a stop block 2213b. One end of the drive arm 2211 has a mounting position. The main body of the locking block 2213a is rotatably connected to the mounting position, and its end facing the handle 2212 is connected to the handle 2212. This connection can be a plug-in, threaded, adhesive, or integrally molded connection. The other end has multiple limiting grooves circumferentially arranged along its rotation direction, each limiting groove fixing a different rotation angle. A stop block 2213b is also provided within the mounting position. The stop block 2213b can slide with the drive arm 2211 and is equipped with a return spring, causing it to abut against one of the limiting grooves, thus creating different included angles between the handle 2212 and the drive arm 2211.
