Description

Technical Field

[0001] The present application relates to the technical field of fishing gear, and in particular to a back plug for a fishing rod. Background Art

[0002] When fishing, a safety line is often used. It serves two functions: preventing the rod from falling into the water and preventing a large fish from biting. It also increases the range of the fish's maneuvering, thus reducing its energy. The safety line has two quick hooks at each end: one for attaching to a fishing box or platform, and the other for attaching to the back stop at the end of the rod handle.

[0003] The existing back plug has the following disadvantages: the hand ring of the existing back plug mostly adopts a hanging design, and the hand ring is hung on the back plug, which has low strength and is easy to break; the hand ring is easy to hurt the hand during actual use, and even scratch the hand; the hand ring is located at the bottom of the fishing rod, which is not convenient for storage and is easily damaged during transportation, making it inconvenient for practical use.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this 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.

[0029] Example

[0030] like Figures 1 to 3 As shown, a back plug for a fishing rod is provided with a connecting rod 1, the outer end of the connecting rod 1 is provided with a wire binding hole 11, and an adjustment mechanism 2 is provided. The adjustment mechanism 2 includes a guide sleeve 21 and a sliding sleeve 22. The sliding sleeve 22 is movably arranged in the guide sleeve 21. The outer side surface of the sliding sleeve 22 is provided with a positioning protrusion 221, and the inner side surface of the guide sleeve 21 is provided with a limiting groove 211 of different depths. The positioning protrusion 221 is arranged in the limiting groove 211. The connecting rod 1 and the sliding sleeve 22 are linked together. In this embodiment, the connecting rod 1 and the sliding sleeve 22 are fixedly connected by bolts.

[0031] The back stopper is installed at the tail of the fishing rod, and the connecting rod 1 is extended outward through the adjusting mechanism 2 until the binding hole 11 extends out from the bottom of the back stopper, and the safety rope is tied in the binding hole 11. When encountering a big fish, the fishing rod is loosened to unload the force, which can avoid the rod from exploding. After the force of the big fish weakens, the fishing rod can be pulled back through the safety rope; when the fishing rod is stored, the connecting rod 1 is pushed into the back stopper through the adjusting mechanism 2 to protect the connecting rod 1.

[0032] The limiting groove 211 includes a first limiting groove 2111 and a second limiting groove 2112. The depth of the first limiting groove 2111 is greater than the depth of the second limiting groove 2112. There are multiple first limiting grooves 2111 and the same second limiting grooves 2112. The first limiting grooves 2111 and the second limiting grooves 2112 are staggered along the circumference of the guide sleeve 21. In this embodiment, there are four first limiting grooves 2111 and four second limiting grooves 2112. This allows the positioning protrusion 221 to slide smoothly within the limiting groove 211, while taking into account the difficulty of manufacturing the guide sleeve 21 and the sliding sleeve 22.

[0033] The sliding sleeve 22 rotates in the guide sleeve 21, the positioning protrusion 221 enters the first limiting groove 2111 and slides to the bottom of the first limiting groove 2111, and the connecting rod 1 linked with the sliding sleeve 22 extends outward and is blocked after the wire binding hole 11 extends out, which can conveniently connect the hand rope; the sliding sleeve 22 rotates in the guide sleeve 21, the positioning protrusion 221 enters the second limiting groove 2112, and the connecting rod 1 linked with the sliding sleeve 22 retracts inward and can be conveniently stored.

[0034] The first limiting groove 2111 and the second limiting groove 2112 have the same width, which can simplify the structure within the guide sleeve 21. There are also multiple positioning protrusions 221, the number of which is the same as the number of the first limiting grooves 2111, and the positioning protrusions 221 are evenly distributed along the circumference of the sliding sleeve 22. In this embodiment, there are also four positioning protrusions 221, each of which is located in a corresponding limiting groove 211. The positioning protrusions 221 and the positioning grooves 211 cooperate with each other to jointly control the movement direction of the sliding sleeve 22 within the guide sleeve 21, thereby improving the reliability of the adjustment mechanism 2.

[0035] The first limiting groove 2111 and the second limiting groove 2112 are both provided with an inclined transition surface 2113 at the groove openings, and the inner end of the positioning protrusion 221 is provided with a transition tooth 2211, and the tooth surface shape of the transition tooth 2211 is adapted to the transition surface 2113; when the positioning protrusion 221 needs to switch between the first limiting groove 2111 and the second limiting groove 2112, the transition tooth 2211 and the transition surface 2113 cooperate with each other, so that the positioning protrusion 221 can smoothly enter the required limiting groove 211.

[0036] The adjustment mechanism 2 is further provided with a compression spring 23 , which is arranged in the guide sleeve 21 ; the inner end of the compression spring 2323 abuts against the sliding sleeve 22 and presses the sliding sleeve 22 toward the bottom of the limiting groove 211 .

[0037] In the absence of external force, the compression spring 23 presses the sliding sleeve 22 toward the bottom of the limiting groove 211, so that the positioning protrusion 221 is pressed against the bottom of the limiting groove 211, preventing the sliding sleeve 22 from rocking back and forth along the axial direction of the guide sleeve 21.

[0038] The adjusting mechanism 2 is further provided with a pressure seat 24 . The pressure seat 24 is provided at the outer end of the guide sleeve 21 , and the outer end of the compression spring 23 rests on the pressure seat 24 .

[0039] The outer end of the positioning protrusion 221 is provided with a guide portion 2212, and the inner end of the pressure seat 24 is provided with a pushing block 241, which faces the guide portion 2212; the guide portion 2212 is provided with a guide surface inclined to one side, and the pushing block 241 is provided with a pushing surface adapted to the guide surface.

[0040] like Figures 4 and 5 As shown, a support tube 3 is also provided, and a guide sleeve 21 is arranged in the support tube 3; an end cover 31 is provided at the bottom end of the support tube 3, and a connecting through hole 311 is provided on the end cover 31, and a connecting rod 1 passes through the connecting through hole 311 and is movably arranged in the connecting through hole 311.

[0041] The support tube 3 is provided with a threaded portion 32 on the outside, and the threaded portion 32 is provided with an external thread, which can be conveniently connected to the fishing rod.

[0042] like Figure 5 and Figure 6 As shown, pressing the connecting rod 1 inward pushes the sleeve 22 to move inward along the guide sleeve 21 until the guide portion 2212 abuts against the pushing block 241. The pushing surface and the guide surface cooperate with each other to control the direction of the circumferential rotation of the sleeve 22, so that the positioning protrusion 221 can smoothly switch between the first limiting groove 2111 and the second limiting groove 2112, thereby realizing the rapid conversion of the connecting rod 1 between the extended and retracted states.

[0043] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
