Description of the invention (1) [Technical field to which the invention belongs] (Please read the precautions on the back before filling out this page) The present invention is used to fit and fix two fishing rod bodies connected in the form of extraction. Mosaic structure. [Known technology] In the conventional fishing rod, a plurality of cylindrical fishing rod bodies can be sequentially inserted into the fishing rod body from the fishing rod body on the front side. When fishing, each fishing rod body is sequentially drawn out to the front side to be fitted and fixed to form a fishing rod body for use. On the other hand, when it is to be accommodated, the fishing rod body on the front side is sequentially accommodated in the fishing rod body on the root side, and the size is reduced. In the traditional draw-out fishing rod, the main rod and the main rod are adjusted. There is a certain way to change the overall length of the rod to fish. The main rod of the fishing rod treated in this manner has a first fitting portion on the inner peripheral surface of the front side end portion that can be fitted to the outer peripheral surface of the root side end portion of the main upper rod having a diameter slightly smaller than that of other portions, and There is also a second fitting part that can be fitted to the outer peripheral surface of the root-side end of the main upper pole with a smaller diameter than the other part. In a state where the main upper rod connected to the front side of the main rod is pulled out to the front side (hereinafter referred to as the “extended state”), the first fitting portion of the main rod is fitted to the outer peripheral surface of the root side end portion of the main upper rod. , And in a state where the main upper pole is inserted into the main pole (hereinafter referred to as a "receiving state"), the second fitting portion of the main pole and the root side end of the main upper pole inserted into the second fitting portion The outer peripheral surface of the part is fitted together. In this way, the main pole and the main pole can be fitted and fixed to each other regardless of whether they are in the "extended state" or "contained state". The paper size can be changed according to the conditions. The Chinese National Standard (CNS) A4 specification (210X297 mm) is applicable. ) -4-524663 A7 B7 V. Description of the invention (2) The whole length is used for fishing. (Please read the precautions on the back before filling out this page.) [Problems to be solved by the invention] In this type of fishing rod, the position where the main rod is fitted in the "extended state" and "contained state" is different, and the main rod There is only one place on the pole (the outer peripheral surface of the root end). Therefore, if it is used repeatedly for a long time, the abrasion of the root end portion as the fitting surface of the main upper rod side will be significant, especially the peripheral end of the root end portion will be severely damaged. Wear caused by prolonged use will also result in reduced mating force. The object of the present invention is to provide a fitting structure of a fishing rod body that can maintain sufficient fitting force even after a long period of time with a simple structure. [Means for solving the problem] Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The fitting structure of the first invention is a fitting structure of a cylindrical fishing rod body connected in a pull-out form, and includes a large-diameter fishing rod body having a cylindrical fitting member in a root-side end portion, and It is connected to the front side of the large-diameter fishing rod body in the form of extraction and has a certain range in the axial direction from the end of the root side. The diameter of the outer peripheral surface is made small and can be inserted into the fitting member. The small diameter fishing rod body. In this structure, in the extended state where the small-diameter fishing rod body is drawn out to the front side of the large-diameter fishing rod body, it is like a normal drawn-out fishing rod. The inner side of the front side of the diameter fishing rod body. At this time, the small-diameter paper size of the small-end end of the small-diameter fishing rod body applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -5-524663 A7 __B7 V. Description of the invention (3) (Please read first Note on the back, please fill in this page again.) The connection part has no relationship with the external diameter of the small diameter fishing rod body and the large diameter fishing rod body. In addition, the peripheral edge portion of the root-side end of the small-diameter fishing rod body does not directly contact the inner periphery of the front-side end of the large-diameter fishing rod body. On the other hand, in the storage state where the small-diameter fishing rod body is inserted into the large-diameter fishing rod body, the small-diameter engaging portion on the outer periphery of the root-side end of the small-diameter fishing rod body is inserted and fitted into the fitting member. At this time, the portion other than the small-diameter joint at the root-side end of the small-diameter fishing rod body is not inserted into the fitting member, and has nothing to do with the small-diameter fishing rod body and the large-diameter fishing rod body being fitted. After the fishing rod body is manufactured, a part of the outer peripheral surface of the root-side end portion of the small-diameter joint portion can be easily processed, and manufacturing is also easy. The fitting structure of the second invention printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is a fitting structure of a cylindrical fishing rod body connected in a pull-out form. The fitting structure includes a cylindrical shape at the end of the root side. The large-diameter fishing rod body of the fitting member is connected to the front side of the large-diameter fishing rod body in a withdrawn form, and has an inverse taper rod treatment on its outer peripheral surface in a certain range from the root end to the axial direction. As the diameter decreases toward the root side, it can be fitted into an inverse tapered rod portion in a fitting member or a small-diameter fishing rod body with a straight rod portion that has no change in outer diameter. This structure also has the same effect as the first invention described above. That is, in the extended state where the small diameter fishing rod body is drawn out to the front side of the large diameter fishing rod body, the reverse tapered rod portion or straight rod portion of the root side end portion of the small diameter fishing rod body is related to the small outer diameter. The diameter fishing rod body is not related to the installation of the large diameter fishing rod body. The peripheral edge of the root end of the small-diameter fishing rod body will not apply to the Chinese national standard (CNS) A4 (210X297 mm). -6-524663 A7 B7 ________ 5.

On the other hand, when the small-diameter fishing rod body is inserted into the large-diameter fishing rod body, only the inverse tapered or straight rod portion on the outer periphery of the root-side end of the small-diameter fishing rod body is inserted and fitted into the insert.合 组合 内。 Inside the component. In addition, after the fishing rod body is manufactured, a part of the outer peripheral surface of the root-side end portion can be easily cut and the manufacturing can be easily performed. The fitting structure of the third invention is the invention of claims 1 or 2, wherein the fitting member of the large-diameter fishing rod body is integrally formed with the large-diameter fishing rod body as part of its structure. In this structure, the fitting member is formed as a part of the large-diameter fishing rod body 'without the need for another fitting member, and the structure does not fall off from the large-diameter fishing rod body. [Inventive embodiment] The first embodiment of the present invention will be described below with reference to the drawings. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints a fishing line that can be inserted into a fishing rod using the first embodiment of the present invention. As shown in FIG. 1, the fishing rod has a main rod 1 and a main rod connected to the front side of the main rod 1. The upper pole 2, the first middle pole 3, the second middle pole 4, connected to the front side of the main upper pole 2, and the front thin rod 5, which is connected to the front side of the second middle pole 4. These main rods 1 to 5 are thin cylindrical members formed by immersing a synthetic resin in a prepreg material such as carbon fiber or glass fiber (see Fig. 2 and the like). In addition, the main upper rod 2 to the front thin rod 5 can be inserted in and out from the front side in order to be sequentially inserted into the rod body side, and are connected in a so-called pull-out form. The number of fishing rod bodies is based on the entire length of the fishing rod according to the requirements. The national paper standard (CNS) A4 specification (210X297 mm) TTZ '524663 A7 __B7 _ V. Description of the invention (5) When The setting is not limited to five, and any number can be used. The main rod 1 is provided with a reel that can be detachably installed on the outer peripheral surface (please read the precautions on the back before filling this page). The reel holder 8 of the reel 7 is equipped with a removable tail at the end of the root. Suppository 1 0. The main upper rod 2 is formed with a fishing line introduction port 9 formed on the front outer peripheral surface for introducing the fishing line L from the reel 7 into the inside of the pole body, and is fixedly arranged to cover the fishing line introduction port. 9 fishing line guide G. A top guide 6 is installed at the front end of the front slim rod 5. The fishing line L from the reel 7 is guided to the fishing line passage through the fishing line guide G and the fishing line introduction port 9, and from the front side The top guide base 6 is guided to the outside. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, as shown in Figure 2. The main pole 1 is a cylindrical body with a slightly tapered front end. The inner side of the root is inserted and fixed. The short cylindrical fitting member 20. A threaded portion is formed on the inner peripheral surface of the root end portion of the fitting member 20, and a tail bolt portion 10 is detachably attached here. The front end portion of the fitting member 20 may be subjected to processing such as chamfering. On the other hand, as shown in Fig. 5, the fitting member 20 may be provided with grooves 20a in the long axis direction at intervals on the inner peripheral surface in the outer peripheral direction. By forming a plurality of such grooves 20a, the main upper pole 2 can be prevented from being sucked out and sucked out when it is fitted into the main upper pole 2 described later. On the other hand, the main upper pole 2 is also a cylindrical body that has been tapered with a thinner tip. The outer peripheral surface of the end of the root side is within a certain range (about 70 to 80 mm from the side of the root. Range) is formed with a fitting surface 2 a having a slightly larger diameter than the other portions. In addition, from the end of the root side of this fitting surface 2a, a certain range in the axial direction (a range of about 10 to 15 mm) is formed, and a small-diameter joint 30 having a small diameter is formed. This paper size applies to Chinese National Standard (CNS) A4 specification (210 × 297 mm) 524663 A7 B7 V. Description of the invention (6) (Please read the precautions on the back before filling this page) Outer diameter of the mating surface 2 a It is larger than the inner diameter of the fitting member 20, and the outer diameter of the small-diameter joint portion 30 is set to approximately match the inner diameter of the fitting member 20. This design is made by making the diameter of the root-side end portion of the main upper rod 2 slightly larger, and then honing and cutting the outer peripheral surface of the root-side end portion thereof. The fishing line with this structure can be inserted into a fishing rod. When fishing, the fishing rod bodies are sequentially pulled out toward the front side, and the fishing rod bodies are sequentially inserted in the form of extraction to use as a fishing rod. On the other hand, when the fishing rod body is to be accommodated, the fitted state of the fishing rod bodies is released, and the fishing rod body on the front side is sequentially stored in the fishing rod body on the root side to be miniaturized. In addition, the main pole 1 and the main upper pole 2 are not only in a state where the main upper pole 2 is pulled out from the main pole 1 (extended state). They can also be fitted together in the storage state, and the length of the entire fishing rod can be adjusted. fishing. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In other words, in the extended state where the main upper pole 2 is pulled out to the front side of the main pole 1, like the usual fishing rod, the outer circumference of the main pole side of the main upper pole 2 The mating surface 2 a is fitted and fixed to the front inner peripheral surface of the main rod 1. At this time, the small-diameter joint 30 of the root-side end of the main upper pole 2 has nothing to do with the fitting. In addition, the periphery of the root-side end of the main upper pole 2 does not touch the inner periphery of the front-side end of the main pole 1. On the other hand, as shown in FIG. 3, in the storage state in which the main upper pole 2 is inserted into the main pole 1, the small-diameter joint portion 30 of the root-side end of the main upper pole 2 is inserted and fitted into The fitting member 20 is inside. At this time, the portion other than the small-diameter joint portion 30 of the root-side end of the main upper pole 2 is not inserted into the fitting member 20, and the main upper pole 2 and the main pole 1 are not fitted. -9-This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 524663 A7 B7 V. Description of the invention (7) [Second embodiment] The following describes the second embodiment of the present invention with reference to the drawings state. As shown in FIG. 4, the main upper rod 52 of the fishing rod adopting the second embodiment of the present invention is also a cylindrical body that has been treated with a tapered rod with a thinner tip. The outer peripheral surface of the root side end is the same as the first In the same embodiment, a fitting surface 5 2 a having a diameter slightly larger than that of the other parts is formed in a certain range (a range of about 70 to 80 mm from the root of the stem). On the other hand, the root-side portion of this mating surface 5. 2 a is, in detail, 'a certain range from the root-side end toward the axial direction (for example, a range of about 10 to 30 mm). It is the reverse taper rod process that the diameter becomes smaller toward the root side, and becomes the reverse taper rod part 60. The outer diameter of this fitting surface 5 2 a is larger than the inner diameter of the fitting member 20, and the outer diameter of the inverse tapered rod portion 60 is set to be insertable into the fitting member 20. This design is made by making the diameter of the root-side end of the main upper rod 2 slightly larger, and then honing and cutting the outer peripheral surface of the root-side end of the rod. In the case where such a fitting structure is adopted, it is preferable that the female side portion fitted in the inverse tapered rod portion 60 is formed to have an inner diameter that is tapered to fit the inverse tapered rod portion. The fishing line having this structure can be inserted into a fishing rod, and the same effect as that of the first embodiment can be achieved. In other words, in the extended state where the main upper pole 5 2 is drawn out to the front side of the main pole 1, like the usual fishing rod, the fitting surface 5 2 a is the outer peripheral surface of the root side of the main upper pole 5 2. The fitting is fixed to the front inner peripheral surface of the main rod 1 (see FIG. 4). At this time, the reverse tapered rod portion 60 of the root-side end of the main upper rod 2 has nothing to do with the fitting. And the peripheral edge of the root end of the main upper pole 5 2 will not touch the inner periphery of the front side of the main pole 1.

Description of Invention (8) On the other hand, when the main upper pole 5 2 is inserted into the main pole 1, the inverse tapered stem portion 60 of the root-side end of the main upper pole 2 is inserted and fitted into the fitting member 20. . At this time, the portion other than the reverse tapered rod portion 60 at the root-side end of the main upper pole 2 is not inserted into the fitting member 20, and is not related to the fitting of the main upper pole 2 and the main pole 1. [Other Implementation Modes] (a) FIG. 6 is a diagram showing the relationship between the main pole 1 and the main upper pole 72. The relationship between the taper changes of the two fishing rod bodies can be distinguished even if the root-side portion of the fitting surface 7 2 a on the outer periphery of the root-side end of the main upper rod 72 is made into a straight rod portion 80 having no change in taper. In the extended state and the stored state, the main pole 7 2 is embedded in the main pole 1 and can also achieve the same effect as the above embodiment. (b) In each of the above-mentioned embodiments, although the fitting member 20 is formed separately from the main rod 1 to be fixed by embedding it, the inner diameter of the root-side end of the main rod 1 may be reduced in a certain range. To use a part of the inner peripheral surface of the main rod 1 as the fitting member 20. [Effects of the Invention] With the fitting structure of the present invention, a sufficient fitting force can be maintained over a long period of time. [Illustration of the drawing] Fig. 1 is a fishing line that can be inserted through the fishing line according to the first embodiment of the present invention.
