Description

Technical Field

[0001] The utility model relates to the technical field of fishing rods, in particular to a force unloading structure of an inner-line fishing rod. Background Art

[0002] With the increasing popularity of fishing and the continuous advancement of fishing techniques, the design and manufacturing of fishing rods are also constantly improving. Traditional fishing rods generally use an external line routing design, where the fishing line is guided to the rod tip through a series of guide rings mounted on the rod body. In practice, external line routing fishing rods still have some shortcomings, such as line entanglement, friction with external objects, and significant wind resistance during casting. To address these issues, internal line routing fishing rods have emerged. The internal line routing design guides the fishing line from the inside of the rod body, passing it through a conduit or channel inside the rod body, avoiding many of the drawbacks of traditional external line routing designs.

[0003] During fishing, the unloading mechanism (also known as the resistance system or line-releasing device) is a crucial component of a fishing rod, primarily used to control the line tension, particularly when a large fish breaks free, releasing some line to prevent line breakage or rod damage. Traditional fishing rods typically integrate the unloading mechanism into the reel, adjusting the reel's resistance to release and reel the line. This unloading mechanism is typically built into the reel itself, relying on the line to be transferred from the rod's exterior through a wire loop to the reel, making it difficult to precisely control the line tension and payout speed. Utility Model Content

[0004] The main purpose of the utility model is to provide a force unloading structure for an internal line fishing rod, aiming to distribute the fishing line tension more evenly and ensure the stability and effectiveness of the force unloading structure under different fishing conditions.

[0005] To achieve the above-mentioned purpose, the present invention proposes a force unloading structure for an internal line fishing rod, comprising:

[0006] rod body;

[0007] A mounting frame, the mounting frame is inserted into the rod body, the mounting frame is connected to a transmission shaft rotatably along the axial direction of the rod body, one end of the transmission shaft is provided with a force unloading plate, the transmission shaft is sleeved with a winding drum, and one end of the winding drum abuts against the force unloading plate;

[0008] An adjusting knob is screwed onto the tail of the mounting bracket and abuts against the winding drum to enable the winding drum to press or separate the blocking piece.

[0009] In a possible embodiment, a gear set is further included, and the gear set includes:

[0010] A driving bevel gear, wherein the driving shaft gear is connected to a rotating shaft, and the rotating shaft is connected to the mounting frame by rotating along the radial direction of the rod body;

[0011] A driven bevel gear is connected to the transmission shaft and meshes with the driving bevel gear to drive the transmission shaft to rotate.

[0012] In a possible embodiment, one end of the rotating shaft extends out of the outside of the rod body and is connected to a crank handle.

[0013] In a possible implementation manner, a hollow connecting portion is protruded from the rear portion of the mounting bracket, and an outer wall of the connecting portion is provided with a thread for screwing the adjusting knob.

[0014] In a possible implementation, the adjustment knob includes:

[0015] an adjusting cap, the adjusting cap being screwed to the connecting portion;

[0016] An adjusting column, one end of which abuts against the adjusting cap, and the other end of which passes through the connecting portion and abuts against the winding drum.

[0017] In a possible implementation manner, a friction plate is provided between the winding drum and the load-releasing plate.

[0018] The technical solution of the utility model adopts a threaded connection adjusting knob at the tail end of the mounting frame, and the adjusting knob is brought into contact with the winding drum, so that the winding drum can be compressed or separated from the unloading plate, thereby adjusting the resistance of the brake. The threaded connection can ensure that the adjusting knob is firmly fixed on the winding drum to avoid loosening during use. By rotating the adjusting knob, fine resistance adjustment can be achieved to meet the needs of different fishing environments, and there is usually an intuitive relationship between the rotation angle of the adjusting knob and the brake resistance, which is convenient for anglers to adjust according to their needs and gradually reduce the force applied to the unloading plate to make the deceleration process of the winding drum smoother instead of stopping suddenly, providing more stable tension management, and unloading can help prevent overload of the system or parts and reduce wear.

[0026] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] In order to solve the problems in the background technology, the utility model proposes a force unloading structure for an internal line fishing rod.

[0028] Combined with reference Figures 1 to 3As shown, the rod body 10 is the main structure of the fishing rod, which is used to accommodate and fix other components. Its shape can be roughly cylindrical and can be made of engineering plastics, carbon fiber composite materials or alloy materials. The mounting frame 20 is inserted into the rod body 10 and is used to install the transmission shaft 21 and other components. The two ends of the mounting frame 20 can be provided with mounting plates that are adapted to the internal shape of the rod body 10. There is an accommodating space between the two mounting plates. The transmission shaft 21 is rotatably connected between the two mounting plates and is arranged along the axial direction of the rod body 10. A winding drum 212 is sleeved on the transmission shaft 21. The rotation of the transmission shaft 21 can drive the winding drum 212 to rotate, so that the fishing line can be wound. A load-releasing plate 211 is also provided on the transmission shaft 21, and one end of the winding drum 212 abuts against the end face of the load-releasing plate 211. Furthermore, an adjustment knob 30 can be provided at the rear end of the mounting bracket 20. The adjustment knob 30 is threadedly connected to the mounting plate on the mounting bracket 20. The connecting portion 23 can be a hollow protrusion with threads on its outer wall. The adjustment knob 30 can be threadedly connected to this protrusion. The middle portion of the adjustment knob 30 can abut the edge of the spool 212 through the hollow protrusion, thereby pressing or separating the spool 212 from the unloading plate 211. By turning the adjustment knob 30, the pressure between the spool 212 and the unloading plate 211 can be adjusted, thereby controlling the resistance to the rotation of the spool 212 and realizing a braking function. When unloading is required, the pressure between the spool 212 and the unloading plate 211 is increased, increasing friction, thereby preventing the spool 212 from rotating and preventing accidental release of the fishing line. The adjustment knob 30 enables precise braking control, helping anglers better control their fishing line. The design of the adjustment knob 30 makes operation simple and intuitive, and can be easily adjusted even in wet conditions.

[0029] In a possible embodiment, a gear set 50 is further included, and the gear set 50 includes:

[0030] A driving bevel gear 51, the driving shaft gear is connected to the rotating shaft 22, and the rotating shaft 22 is connected to the mounting frame 20 in a radially rotatable manner along the rod body 10;

[0031] The driven bevel gear 52 is connected to the transmission shaft 21 and meshes with the driving bevel gear 51 to drive the transmission shaft 21 to rotate.

[0032] Combined with reference Figure 3As shown, the driving bevel gear 51 is connected to the rotating shaft 22, which is connected to the mounting bracket 20 and rotates along the radial direction of the rod body 10. The rotating shaft 22 provides power for the rotation of the driving bevel gear 51. The driven bevel gear 52 is connected to the transmission shaft 21 and meshes with the driving bevel gear 51. By driving the rotating shaft 22 to rotate, the driving bevel gear 51 can be driven to rotate, thereby driving the transmission shaft 21 to rotate, and further driving the winding drum 212 to rotate, so that the fishing line is wound around the winding drum 212. By providing the gear set 50, the direction of the rotational power can be changed, so that the axially arranged winding drum 212 can rotate. Arranging the winding drum 212 along the axial direction of the rod body 10 can reduce friction between the winding drum 212 and the fishing rod, thereby reducing resistance and making winding smoother. Reduced friction means that wear between the winding drum 212 and other components will also be reduced, extending the service life of the winding drum. The axial arrangement helps maintain the overall balance of the fishing rod and reduce the sense of imbalance during use.

[0033] In a possible embodiment, one end of the rotating shaft 22 extends out of the rod body 10 and is connected to a crank handle 40 .

[0034] Combined with reference Figure 3 As shown, the crank 40 can be used as a power source for the rotating shaft 22 . By rotating the crank 40 , the rotating shaft 22 is driven to rotate, thereby driving the driving bevel gear 51 to rotate.

[0035] In a possible embodiment, a hollow connecting portion 23 is protruded from the rear of the mounting bracket 20 , and a thread is provided on the outer wall of the connecting portion 23 for screwing the adjusting knob 30 .

[0036] Combined with reference Figure 2 As shown, the connecting portion 23 can be integrally formed with the mounting frame 20, and a thread is provided on the outer wall of the connecting portion 23. The adjusting knob 30 is screwed to the connecting portion 23, and the adjusting knob 30 protrudes from the end of the rod body 10, making the adjusting knob 30 easier to operate.

[0037] In a possible implementation, the adjustment knob 30 includes:

[0038] an adjusting cap 31 , the adjusting cap 31 being screwed to the connecting portion 23 ;

[0039] An adjusting post 32 has one end abutting against the adjusting cap 31 , and the other end passing through the connecting portion 23 and abutting against the winding drum 212 .

[0040] Furthermore, the adjusting knob 30 can be composed of an adjusting cap 31 and an adjusting column 32. The adjusting cap 31 is partially provided with an internal thread for threaded connection with the connecting part 23. The adjusting column 32 is partially inserted therein, and the end thereof is pressed against the inside of the adjusting cap 31, and the other end is pressed against the edge of the winding drum 212. Here, since the winding drum 212 is sleeved on the transmission shaft 21, the clamping force applied by the adjusting column 32 to the winding drum 212 can be transmitted through the annular retaining ring. By rotating the adjusting knob 30, the pressure between the winding drum 212 and the unloading plate 211 can be adjusted, thereby controlling the resistance to the rotation of the winding drum 212 and realizing the braking function.

[0041] In a possible implementation manner, a friction plate (not shown) is provided between the winding drum 212 and the load-releasing plate 211 .

[0042] Furthermore, a friction plate can be provided between the winding drum 212 and the unloading plate 211. When unloading is required, the friction force is increased by increasing the pressure between the winding drum 212 and the unloading plate 211, thereby preventing the winding drum 212 from rotating and preventing the fishing line from being accidentally released.
