Description

Technical Field

[0001] This utility model relates to the field of fishing rod technology, and in particular to an internally routed fishing rod that prevents fishing line wear. Background Technology

[0002] As a widely practiced recreational and competitive activity, fishing places high demands on the portability and practicality of fishing tackle. Traditional fishing rods often use an external reel and guide ring structure, with the fishing line laid out along the outside of the rod body. During the casting and unloading process, they are easily affected by external environmental interference, such as wind entanglement and snagging on obstacles, which affects the handling experience. Furthermore, problems such as tangling and knotting of the fishing line are prone to occur during storage and transportation.

[0003] To improve the integration and ease of operation of fishing equipment, existing technologies have proposed an internally guided fishing rod structure that integrates the line retrieval mechanism inside the rod. This structure uses a through-channel inside the rod body and integrates the line retrieval device at the butt end, allowing the fishing line to be retrieved, released, and guided within the rod body. However, most existing internally guided fishing rods use a telescopic structure for convenient storage, but lack effective anti-abrasion structures at the joints between rod sections. When the fishing line passes between different sections, it is easy for it to come into direct contact with the edge of the joint, which can lead to wear and breakage of the fishing line over time, affecting its service life. Utility Model Content

[0004] The main purpose of this invention is to provide an internally routed fishing rod that prevents fishing line wear, thereby reducing the wear of the fishing line inside the rod and increasing its service life.

[0005] To achieve the above objectives, this utility model proposes an internally guided fishing rod to prevent fishing line wear, comprising a rod body, wherein a line channel is provided inside the rod body, and a line winding and unwinding mechanism is inserted at the tail of the rod body for driving the fishing line to be wound up and unwound along the line channel. A guide structure is connected to the front end of the line winding and unwinding mechanism, and a first line outlet hole and a second line outlet hole are respectively provided at both ends of the guide structure. The first line outlet hole and the second line outlet hole are offset in the circumferential direction.

[0006] The rod body includes multiple rod sections that are connected in sequence. Each rod section can extend and retract relative to the other to extend and retract the rod body. Each rod section is fitted into the end of another rod section and has a guide ring structure embedded inside. The center of the guide ring structure has an anti-wear ring for supporting the fishing line passing through the connection point of the two rod sections.

[0007] In one possible implementation, each fishing rod section includes a connecting section and a telescopic section. When the rod body is in the extended state, the connecting sections of adjacent fishing rod sections are interference-fitted; when the rod body is in the retracted state, adjacent fishing rod sections are retracted into the telescopic section.

[0008] The guide ring structure is embedded at the end of the connecting section. After the fishing line passes through the telescopic section of one rod section, it passes through the anti-wear ring and enters the telescopic section of another rod section.

[0009] In one possible implementation, the guide ring structure includes:

[0010] An inner nested ring is embedded at the end of the connecting segment, and the inner wall of the inner nested ring is provided with an internal thread;

[0011] A fixing ring is screwed to the inner nested ring, and a mounting hole is provided at the center of the fixing ring, and the anti-wear ring is embedded in the mounting hole.

[0012] In one possible implementation, the anti-wear ring and the second outlet hole are concentrically arranged.

[0013] In one possible implementation, the inner wall of the telescopic section is spirally wound with anti-wear lines.

[0014] This utility model's technical solution constructs a complete internal line guiding and support structure by setting anti-abrasion lines within the telescopic section of the fishing rod section and setting anti-abrasion rings at the ends of the connecting sections. This effectively guides the fishing line along a preset path, preventing tangling or jamming between the telescopic sections and improving the stability and smoothness of the line path. Since the fishing line is easily damaged by contact with sharp angles or hard edges when passing through the connecting ends between the fishing rod sections, this application sets an anti-abrasion ring at the connecting part. The anti-abrasion ring is made of wear-resistant material, and its surface is set perpendicular to the rod body axis, forming a flexible guide surface. This avoids direct friction between the fishing line and the end face of the rod section, effectively reducing the risk of wear and breakage and extending the service life of the fishing line.

[0023] 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.

[0024] In response to the problems in the background art, and in conjunction with reference Figures 1 to 4 As shown, this utility model proposes an internally guided fishing rod to prevent fishing line wear, comprising a rod body 10, wherein a line channel 11 is provided inside the rod body 10, and a line reeling mechanism 12 is inserted at the tail of the rod body 10 for driving the fishing line to be reeled in and out along the line channel 11. A guide structure 13 is connected to the front end of the line reeling mechanism 12, and a first line outlet hole 131 and a second line outlet hole 132 are respectively provided at both ends of the guide structure 13. The first line outlet hole 131 and the second line outlet hole 132 are offset in the circumferential direction. The rod body 10 includes a plurality of fishing rod sections 14 that are sequentially connected. Each fishing rod section 14 can be extended and retracted relative to each other to realize the extension and retraction of the rod body 10. A guide ring structure 141 is embedded in the end of each fishing rod section 14 that is connected to another fishing rod section 14. An anti-wear ring 1413 is embedded in the center of the guide ring structure 141 for supporting the fishing line passing through the connection point of the two fishing rod sections 14.

[0025] This embodiment provides an internally guided fishing rod to prevent fishing line wear. It includes a rod body 10 formed by sequentially connecting multiple rod sections 14. An axially connected line channel 11 is formed inside the rod body 10. The tail of the rod body 10 is provided with a line-reeling / releasing mechanism 12 for driving the fishing line along the line channel 11. The line-reeling / releasing mechanism 12 is inserted into a cavity at the tail end of the rod body 10 and fixedly connected to it. The front end of the line-reeling / releasing mechanism 12 is connected to a guide structure 13 for limiting the direction of line entry. The guide structure 13 has a first line outlet hole 131 and a second line outlet hole 132 at its opposite ends. The two line outlet holes are circumferentially offset in a cross-section perpendicular to the axis of the rod body 10, meaning that the centers of the two holes do not coincide in azimuth angle and are not located in the same radial direction. This allows the fishing line led out from the front end of the line retrieval mechanism 12 to first enter the guide structure 13 through the first line outlet hole 131, and then be led out through the second line outlet hole 132 and guided in the axial direction of the rod body 10, thus smoothly entering the line channel 11 and avoiding concentrated contact and scraping of the fishing line at a single hole edge at the tail. To reduce friction and wear, the edges of the first line outlet hole 131 and / or the second line outlet hole 132 can be rounded or chamfered, or small ceramic or hard alloy parts can be embedded in the edges; the above forms are optional and do not constitute a limitation on the scope of the claims.

[0026] Each rod section 14 is connected by a cylindrical sleeve and can extend and retract relative to each other along the axis of the rod body 10 to achieve the extension and retraction of the rod body 10. A guide ring structure 141 is embedded inside the end of each rod section 14, and an anti-wear ring 1413 is embedded in the center of the guide ring structure 141. The anti-wear ring 1413 is preferably made of ceramic, hard alloy or other low-friction wear-resistant material, and its inner hole is coaxial with the axis of the rod body 10. It is used to provide low-friction support for the fishing line passing through at the connection transition between two adjacent rod sections 14, so that the fishing line crosses the intersection step and is isolated from the base edge, thereby providing smooth support at each connection and preventing the fishing line from rubbing against the cylindrical wall step and rough edges of the two rod sections 14. The anti-wear ring 1413 can be fixed in the guide ring structure 141 by means of interference fit, adhesive bonding, retaining ring limit or hot riveting. The guide ring structure 141 and the inner wall of the fishing rod section 14 can be reliably assembled by means of interference fit, adhesive bonding or local boss positioning. The above fixing methods are all equivalent implementations.

[0027] During operation, the line reeling and releasing mechanism 12 drives the fishing line along a predetermined path: the fishing line passes sequentially through the first line outlet 131, the guide area, and the second line outlet 132 of the guide structure 13 into the line channel 11, then passes along the axial direction of the rod body 10 through the anti-wear rings 1413 at the joints of each rod section 14 and finally reaches the rod tip; the reeling process is carried out in reverse. Due to the circumferential offset of the first line outlet 131 and the second line outlet 132, the path of the fishing line gradually transitions from lateral to near-axial within the guide structure 13, the contact points are dispersed and the contact angle is reduced, thereby reducing the local contact stress and wear at the end opening; the anti-wear rings 1413 provided at each joint along the way provide a coaxial, smooth, low-friction continuous support interface, preventing the fishing line from directly contacting the cylinder wall steps or burrs, further suppressing wear caused by the extension, bending, and vibration of the rod body 10. Through the synergistic effect of the tail guide structure 13 and the anti-wear rings 1413 of each section, a low-friction line channel 11 is formed that runs from end to end, which effectively improves the service life of the fishing line while ensuring smooth and stable retrieval and release of the fishing line.

[0028] Combined with reference Figure 1 and Figure 2 As shown, in one possible implementation, each fishing rod section 14 includes a connecting section 14a and a telescopic section 14b. When the rod body 10 is in the extended state, the connecting sections 14a of adjacent fishing rod sections 14 are interference-fitted. When the rod body 10 is in the retracted state, adjacent fishing rod sections 14 are retracted into the telescopic section 14b. The guide ring structure 141 is embedded in the end of the connecting section 14a. After the fishing line passes through the telescopic section 14b of one fishing rod section 14, it passes through the anti-wear ring 1413 and enters the telescopic section 14b of another fishing rod section 14.

[0029] In this embodiment, each rod section 14 preferably consists of a connecting section 14a located near the adjacent rod section 14 and a telescopic section 14b connected thereto for accommodating the adjacent rod section 14. When the rod body 10 is in the extended state, the connecting section 14a on the side with the smaller outer diameter and the telescopic section 14b on the side with the larger inner diameter form a finite-length overlapping fit area in the axial direction. The overlapping area adopts an interference fit to obtain coaxial positioning and axial pull-out resistance, thereby maintaining inter-section stability and overall straightness when the rod body 10 is subjected to bending force. When the rod body 10 is in the retracted state, the rod section 14 with the smaller outer diameter retracts axially into the telescopic section 14b of the adjacent rod section with the larger inner diameter, realizing a short-retracted structure in which multiple sections are sequentially inserted. To prevent the fishing line from rubbing against the joints or rough edges, a guide ring structure 141 is embedded at the end of the connecting section 14a of each rod section 14, with an anti-abrasion ring 1413 at its center. The fishing line travels axially from inside the telescopic section 14b of the following rod section 14, passes through the anti-abrasion ring 1413 at the end of the connecting section 14a, and then enters the telescopic section 14b of the preceding rod section 14. This ensures continuous coaxial, low-friction support and guidance at each section transition point via the anti-abrasion ring 1413. This arrangement guarantees mechanical stability in the extended state and compactness and smoothness in the retracted state, while limiting the fishing line path to a repetitive link of telescopic section 14b—anti-abrasion ring 1413—telescopic section 14b, systematically reducing wear.

[0030] Combined with reference Figure 4 As shown, in one possible implementation, the guide ring structure 141 includes:

[0031] Inner nested ring 1411, the inner nested ring 1411 is embedded in the end of the connecting segment 14a, and the inner wall of the inner nested ring 1411 is provided with internal thread;

[0032] A fixing ring 1412 is screwed to the inner nested ring 1411. The fixing ring 1412 has a mounting hole 1412a at its center, and the anti-wear ring 1413 is embedded in the mounting hole 1412a.

[0033] In this embodiment, the inner nested ring 1411 is an annular seat, whose outer circle is interference-fitted or glued to the inner wall of the end of the connecting section 14a. The inner wall of the inner nested ring 1411 is machined with internal threads for a detachable threaded connection with the fixing ring 1412. The fixing ring 1412 is an annular cap with a central opening, and its center is provided with a mounting hole 1412a to accommodate the anti-wear ring 1413. The anti-wear ring 1413 is preferably a ring made of ceramic or hard alloy, and can be fixed in the mounting hole 1412a by interference fit, slot limiting, or adhesive bonding. During assembly, first press the inner nested ring 1411 into the end of the connecting section 14a and position it. Then, insert the anti-wear ring 1413 into the mounting hole 1412a of the fixing ring 1412, ensuring that the inner edge of the hole is rounded. Subsequently, screw the fixing ring 1412 into the inner nested ring 1411 with threads, so that the end face of the fixing ring 1412 reliably clamps the anti-wear ring 1413 at the end of the connecting section 14a. The advantages of this structure are: first, it is easy to replace the anti-wear ring 1413 to adapt to different wire diameters or materials; second, controllable axial clamping force and reliable coaxial positioning can be obtained through thread pre-tightening; and third, the split parts are easy to process and cost-effective, and maintenance does not require damage to the fishing rod section 14 body.

[0034] Combined with reference Figure 1 As shown, in one possible implementation, the anti-wear ring 1413 and the second outlet hole 132 are concentrically arranged.

[0035] In this embodiment, to reduce the angle of incidence of the fishing line between the tail guide and the first guide ring, the anti-abrasion ring 1413 and the second line outlet hole 132 in the guide structure 13 are preferably concentrically arranged, that is, their centers coincide in a cross-section perpendicular to the axis of the rod body 10, and their axes are collinear in the axial direction. Through this geometric relationship, the fishing line, after being led out from the second line outlet hole 132, can enter the inner hole of the anti-abrasion ring 1413 at the end of the connecting section 14a of the adjacent rod section 14 with almost no additional turning required. The angle of incidence is close to zero, significantly reducing the contact stress at the hole edge and the wear per unit length, while improving the smoothness and quietness of line retrieval and release.

[0036] Combined with reference Figure 2 As shown, in one possible implementation, the inner wall of the telescopic section 14b is spirally wound with anti-wear lines 15.

[0037] In this embodiment, to further suppress occasional wall-scratching and multi-point abrasion on the inner wall of the telescopic section 14b, an anti-abrasion line 15 can be spirally wound around the inner wall of the telescopic section 14b in a circumferential direction. The anti-abrasion line 15 can be abrasion-resistant metal wire or a polymer fiber filament coated with a low-friction coating, which is attached or embedded in the inner wall of the telescopic section 14b with a certain pitch to form a continuous spiral support rib. When the fishing line moves within the telescopic section 14b, it only makes intermittent contact with the anti-abrasion line 15 in a line-to-line or point-to-line manner, avoiding large-area wall-to-wall friction; at the same time, the spiral geometry can produce a slight centering effect on the fishing line when the rod body 10 is slightly bent and vibrates, causing it to tend to run closer to the axis, thereby reducing random collisions with the inner wall. The anti-abrasion line 15 can be fixed by prefabricated shallow groove embedding, dot-like adhesive bonding, or local hot pressing, and the pitch and wire diameter can be selected according to the target wire diameter and the desired support stiffness. This arrangement neither significantly reduces the effective channel diameter nor alters the main component structure, yet achieves considerable wear reduction and noise reduction.

[0038] It should be noted that the anti-abrasion line 15 is arranged on the inner wall of the telescopic section 14b of the outer fishing rod section 14, and is preferably embedded in a prefabricated shallow groove so that the outer surface of the anti-abrasion line 15 is basically flush with or slightly lower than the reference surface of the inner wall. In this case, the nominal inner diameter of the telescopic mating surface does not increase, the axial sliding between sections still proceeds along the original cylindrical surface, the equivalent clearance remains unchanged, and there is no risk of interference. For scenarios where slight protrusion is permissible, the maximum radial protrusion of the anti-abrasion line 15 should be less than the nominal radial clearance between adjacent fishing rod sections 14 and a safety margin for manufacturing, tolerance, and thermal expansion should be reserved, that is, a remaining radial clearance should still be maintained under all assembly and use conditions; the protrusion of the anti-abrasion line 15 can be controlled to a small proportion of the nominal clearance (e.g., not exceeding one-third of it), and stable sliding can be ensured by sampling and checking the roundness and straightness of the mating section. Furthermore, to prevent end snagging, the start and end positions of the anti-abrasion line 15 are provided with an axial clearance distance from the end face of the telescopic section 14b. The end transition is a smooth slope or sinks back into the groove, and the adhesive does not overflow onto the inner wall reference surface, thus preventing the formation of steps or sharp corners when sections enter / exit the overlapping mating area. Therefore, the spiral anti-abrasion line 15 only provides intermittent support and central guidance for the fishing line, does not participate in the metal-to-metal contact between the rod sections 14, does not change the force and kinematic relationship of the telescopic fit, and therefore does not affect the smooth extension, retraction, and storage of the rod sections 14.
