Description

Technical Field

[0001] The utility model relates to a fishing rod connector, in particular to a fishing rod connector used for connecting rod sections in a fishing rod, and a butt-jointed fishing rod using the fishing rod connector. Background Art

[0002] A multi-section fishing rod includes a short rod section, a handle rod section, and multiple intermediate rod sections. Each rod section needs to be connected together to form a fishing rod when in use. In the prior art, multi-section fishing rods mainly include two types: telescopic fishing rods and continuous fishing rods. Telescopic fishing rods use an antenna-pullout design and consist of tapered rod sections. Their advantages are: the short rod section and the intermediate rod section can be completely retracted into the handle section, making them easy to carry and not easily pulled out, making them suitable for fishing large fish. Their disadvantages are: the force point is forward, the small rod sections have a large degree of curvature, and the force transmission is non-linear. A continuous fishing rod consists of multiple non-tapered rod sections. When in use, the small rod sections are sequentially inserted into the large rod section. This is also known as an insert rod. Its advantages are: the rod sections fit tightly together and provide excellent waist strength. Its disadvantages are: the center of gravity is forward, the holding feel is slightly heavy, and it is suitable for fishing small fish. In both telescopic fishing rods and continuous fishing rods, the adjacent rod sections are connected using a nested connection structure, where the thinner rod section is inserted into the thicker rod section, and the thicker rod section is nested outside the thinner rod section. This nested connection structure has the following disadvantages: First, due to the influence of the rod section wall thickness, the diameter of the rear rod section must be at least 2-6 mm larger than the diameter of the front rod section. When there are many rod sections, the diameter of the handle section is very large and even difficult to grasp. Second, the connection between adjacent rod sections forms a circular step, and the diameter of the fishing rod changes in a stepped manner. When the fishing rod is subjected to force, the fishing rod deforms and the force is uneven. Third, each rod section is a hollow tube. During the assembly or disassembly of the fishing rod, water and sand can easily enter the rod section. During the insertion and removal of the rod section, sand particles can scratch the rod section connection, forming a structural weakness. Especially for carbon fiber fishing rods, this damage is fatal and will shorten the service life of the fishing rod. Fourth, it is difficult to adjust the length of the fishing rod during use. The number of rod sections cannot be increased or decreased for a telescopic fishing rod, and although the number of rod sections can be increased or decreased for a continuous fishing rod, since the tail end of each intermediate rod section cannot be equipped with a tail plug and a safety line, it is also difficult to adjust the length of the fishing rod by increasing or decreasing the number of rod sections. It is necessary to equip fishing rods of various specifications to adapt to different fishing environments. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a fishing rod connector which can connect adjacent rod sections of the fishing rod in a docking manner, overcoming the shortcomings of the stacking connection structure, and having the advantages of simple structure, easy use, and not easy to become disconnected.

[0004] The technical solution adopted to solve the technical problem: a fishing rod connector, including a connecting sleeve fixed in the connecting end cylinder of adjacent rod sections, and a connecting rod connecting two adjacent connecting sleeves, an internal thread is provided on the inner wall of the connecting sleeve, and an external thread matching the internal thread of the connecting sleeve is provided on the rod body of the connecting rod.

[0005] As a further improvement of the present invention: the outer wall of the connecting sleeve has a conical surface or a cylindrical surface that fits with the inner wall of the corresponding rod section connecting end cylinder.

[0006] As a further improvement of the present invention: the connecting sleeve is glued and fixed to the rod joint cylinder, and a glue injection groove is provided on the outer wall of the connecting sleeve so that glue can enter from the outside of the rod joint into the space between the outer wall of the connecting sleeve and the inner wall of the rod joint cylinder.

[0007] As a further improvement of the present invention: the connecting sleeve is a barrel-shaped connecting sleeve with a sealed bottom.

[0008] As a further improvement of the present invention, a limit stopper protruding from the cylindrical surface of the rod body is provided in the middle of the connecting rod.

[0009] As a further improvement of the present invention: the limit baffle is a frustum-shaped baffle, and the diameters of the circular end faces on both sides of the frustum are respectively equal to the outer diameters of the connecting end faces of the corresponding side rod section cylinders.

[0010] Another technical problem to be solved by the utility model is to provide a butt-jointed fishing rod using a fishing rod connector, which can overcome the shortcomings of the stepped diameter changes of the rod sections in the telescopic fishing rod and the continuous fishing rod. When in use, the force and deformation of the fishing rod become more uniform, and the overall toughness of the fishing rod is better.

[0011] The technical solution adopted to solve the technical problem: a docking fishing rod, including a tip rod section, a handle rod section and multiple middle rod sections, the tip rod section and the middle rod section, the middle rod section and the middle rod section, and the middle rod section and the handle rod section are connected by fishing rod connectors.

[0012] As a further improvement of the present invention: the middle rod section is a conical rod section with a front end diameter smaller than a rear end diameter, and the internal thread of the connecting sleeve in the front end cylinder of the middle rod section and the external thread of the connecting rod are fixed by gluing.

[0013] As a further improvement of the present invention: the fishing rod also includes a plurality of tail plugs corresponding to the number of intermediate rod sections and the diameter of the tail end, each tail plug can be installed to the tail end of the corresponding intermediate rod section, the tail plug includes a plug and a plug rod, and the plug rod is provided with an external thread that cooperates with the connecting sleeve in the corresponding intermediate rod section tail end cylinder.

[0014] As a further improvement of the present invention, all the rod sections are connected end to end in sequence to form a conical fishing rod with a smooth surface.

[0015] Beneficial effect: The fishing rod connector of the present invention comprises a connecting sleeve fixed in the connecting end cylinder of adjacent rod sections, and a connecting rod connecting two adjacent connecting sleeves, an internal thread is provided on the inner wall of the connecting sleeve, and an external thread matching the internal thread of the connecting sleeve is provided on the rod body of the connecting rod. The technical features overcome the disadvantages of not being able to turn threads on the rod sections of carbon fiber fishing rods and not being able to use threaded connections by fixing the connecting sleeve with threads in the rod sections. The connecting rod is used to tighten and connect adjacent rod sections, thereby realizing the connection of adjacent rod sections in a docking manner. The connecting parts of adjacent rod sections do not have an overlapping connection structure, thereby overcoming the shortcomings of the overlapping connection structure used in the prior art. The fishing rod connector has a simple structure, low production cost, and is easy to use. Since a threaded connection is used, sliding and disconnection between rod sections during use can be effectively avoided, making the connection more secure. Due to the technical feature that the outer wall of the connecting sleeve has a conical surface that fits with the inner wall of the corresponding rod joint connecting end cylinder, the integrity of the connecting sleeve and the rod joint is better, and the connecting sleeve can support the cylinder at the end of the rod joint from the inside, so the strength of the rod joint is better. Since the connecting sleeve and the rod joint cylinder are glued and fixed, a technical feature is provided on the outer wall of the connecting sleeve, which allows glue to enter from the outside of the rod joint into the outer wall of the connecting sleeve and the inner wall of the rod joint cylinder. The connecting sleeve and the rod joint cylinder are glued and fixed without damaging the structure of the rod joint. The glue injection groove can allow the glue to fully enter between the connecting sleeve and the rod joint cylinder, resulting in better bonding effect. When the rod joint is frustum-shaped, during the production process, the connecting sleeve at the small diameter end can be installed from the large diameter end of the rod joint without gluing, and pushed to the other end. After the connecting sleeve is tightly fitted to the inner wall of the small diameter end rod joint cylinder, the glue injection groove is used to inject glue to bond and fix the connecting sleeve to the inner wall of the small diameter end rod joint cylinder, thereby avoiding the connection sleeve being difficult to move inside the rod joint cylinder when glue is first applied and then installed into the rod joint, or the glue will be rubbed onto the inner wall of the cylinder during movement. Due to the technical feature that the connecting sleeve is a barrel-shaped connecting sleeve with a sealed bottom, the connecting sleeve is used to seal the end of the rod joint, so that water and sand will not enter the rod joint, and the interior of the rod joint will not be penetrated after the rod joint is connected, the fishing rod feels better when used and has a longer service life. Due to the technical feature that a limit block protruding from the cylindrical surface of the rod body is provided in the middle of the connecting rod, the necessary contact length between the connecting rod and the connecting sleeves on both sides is ensured, avoiding the situation where the contact length with the connecting sleeve on one side is large and the contact length with the connecting sleeve on the other side is small. At the same time, it can also effectively avoid direct compression and friction between the ends of the two rod joints during the assembly of the rod joint, resulting in damage to the end faces. Due to the technical feature that the limit block is a frustum-shaped block, the diameter of the circular end faces on both sides of the frustum is equal to the outer diameter of the connecting end face of the corresponding rod joint cylinder, the outer wall transition of the adjacent rod joint connection is smoother, and no annular step is formed at the connection.The present invention adopts a docking type fishing rod using a fishing rod connector. Due to the technical feature that the docking type fishing rod using the fishing rod connector includes a short rod section, a handle rod section and multiple intermediate rod sections, and the short rod section and the intermediate rod section, the intermediate rod section and the intermediate rod section, and the intermediate rod section and the handle rod section are connected by the fishing rod connector, the docking type fishing rod overcomes the restriction of the diameter difference of adjacent rod sections by the stacked connection structure of the vibrating fishing rod and the continuous fishing rod, so that the diameter difference of adjacent rod sections can be smaller, the overall diameter change of the fishing rod can be more gradual, the force applied to the fishing rod during use is more uniform, the arc formed when bending is smoother, and the overall strength of the fishing rod is better. Due to the adoption of the technical solution that the intermediate rod section is a cone-shaped rod section with a front end diameter smaller than the rear end diameter, the internal thread of the connecting sleeve in the front end cylinder of the intermediate rod section and the external thread of the connecting rod are fixed by gluing, and the connecting rod is fixed to the front end of the intermediate rod section. During the assembly process, it is only necessary to screw the connecting rod to the connecting sleeve at the rear end of the front rod section, which is faster to assemble and easier to operate. Since the fishing rod using the fishing rod connector also includes a plurality of tail plugs corresponding to the number of intermediate rod sections and the diameter of the tail end, each tail plug can be installed to the tail end of the corresponding intermediate rod section, and the tail plug includes a plug and a plug rod, and the plug rod is provided with a technical feature of an external thread that cooperates with the connecting sleeve in the barrel of the corresponding intermediate rod section tail end. When in use, the number of rod sections can be reasonably selected according to needs, and the corresponding tail plug is installed at the tail end of the last rod section, and fishing rods with different numbers of sections and lengths can be assembled to meet the use requirements of different environments. Due to the technical feature of forming a smooth-surfaced conical fishing rod after all the rod sections are connected in sequence, the assembled fishing rod has a more beautiful appearance, more uniform force, better feel in use, and higher overall strength.

[0021] like Figure 1 、 Figure 3As shown, the fishing rod connector of the present invention includes two connecting sleeves 5 fixed in the connecting end cylinders of adjacent rod sections, and a connecting rod 6 connecting the two adjacent connecting sleeves. An internal thread is provided on the inner wall of the connecting sleeve, and an external thread 61 that matches the internal thread of the connecting sleeve is provided on the rod body of the connecting rod.

[0022] The outer wall of the connecting sleeve has a conical surface 52 or a cylindrical surface that fits with the inner wall of the corresponding rod joint connecting end cylinder. The connecting sleeve is glued and fixed to the rod joint cylinder. A glue injection groove 51 is provided on the outer wall of the connecting sleeve to allow glue to enter from the outside of the rod joint into the space between the outer wall of the connecting sleeve and the inner wall of the rod joint cylinder. Figure 1 The glue injection grooves in the embodiment are double-helical, but other shapes can also be used in actual production. During the production process, after the connecting sleeve is pushed into the position where it needs to be fixed in the rod tube, glue is injected into the gap between the connecting sleeve and the rod tube through the glue injection grooves, thereby fixing the connecting sleeve to the rod tube.

[0023] Preferably, the connecting sleeve is a barrel-shaped connecting sleeve with a bottom seal 53. When the barrel-shaped connecting sleeve with a bottom seal is installed at both ends of a rod section, the cylinder of the rod section will be sealed from both ends, thereby preventing water and sand from entering the cylinder of the rod section.

[0024] Preferably, a limit block 62 protruding from the cylindrical surface of the rod body is provided in the middle of the connecting rod. The limit block is a cone-shaped block, and the diameters of the circular end surfaces on both sides of the cone are equal to the outer diameters of the corresponding side rod section cylindrical connection end surfaces 211 and 221, respectively. In this way, the transition between adjacent rod sections after connection is smoother, and no annular steps will be formed at the connection part of the rod sections.

The tip rod section and the intermediate rod section, the intermediate rod section and the intermediate rod section, and the intermediate rod section and the handle rod section are connected using the fishing rod connector. Figure 2 While only two intermediate rod sections are shown in the embodiment, this does not necessarily mean that there are only two intermediate rod sections. In actual production, the number of intermediate rod sections typically ranges from 1 to 10. The short rod section and all the intermediate rod sections are connected end to end to form a smooth, tapered rod body. The number of fishing rod connectors is determined by the total number of fishing rod sections. The diameters of the connecting sleeve and connecting rod in the fishing rod connector are reasonably determined by the diameters of the two rod sections it connects, i.e., the diameters of the connecting sleeve and connecting rod gradually increase in thickness from the short rod section to the handle section.

[0026] Preferably, the middle rod section is a conical rod section with a front end diameter smaller than a rear end diameter, and the internal thread of the connecting sleeve in the front end cylinder of the middle rod section and the external thread of the connecting rod are fixed by gluing.

[0027] like Figure 4As shown, the fishing rod also includes a plurality of tail plugs 4 corresponding to the number of intermediate rod sections and the diameter of the tail end. Each tail plug can be installed to the tail end of the corresponding intermediate rod section. The tail plug includes a plug 41 and a plug rod 42. The plug rod is provided with an external thread 43 that cooperates with the connecting sleeve in the corresponding intermediate rod section tail end cylinder, and the plug is provided with a connecting ring for connecting a safety rope.

[0028] During use, the number of rod sections combined into a fishing rod can be reasonably determined according to the use environment, a short rod section and several intermediate rod sections can be assembled together, and a corresponding tail plug can be installed at the tail end of the last intermediate rod section. The last intermediate rod section can be used as a handle section to achieve the purpose of adjusting the length of the fishing rod.

[0029] The fishing rod connector of the present invention can be made of metals such as aluminum, copper, aluminum alloy, copper alloy, or engineering plastics such as nylon and polyphenylene sulfide, and the rod joint can be made of carbon fiber, glass fiber and epoxy resin.
