DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting rod, and more particularly, to a structure for attaching a former rod and a former rod in a connecting rod.

[0002]

2. Description of the Related Art Splicing rods used in conventional life issuance techniques employ a splicing technique such as parallel splicing or inro splicing. The former is a method of press-fitting the former rod into the former rod (see FIG. 5), and the latter is a method of press-fitting the former rod into the projecting reduced diameter portion of the former rod. (Using a joint fitting at the joint, insert the insertion fitting provided at the rear end of the rod with the guide ring into the receiving fitting provided at the tip of the original rod for setting the reel. And a structure that connects the rod.)

[0003]

When adopting the above-mentioned conventional splicing method, the most important point for the user is that the position of the reel attached to the original rod in the circumferential direction and the rod should be It must be inserted so that the circumferential position of the attached guide ring matches. However, even if they are carefully inserted along the mark so that the position of the former rod and the former rod does not shift, there are many cases where they do not match easily, and it is necessary to reinsert each time.

[0004] In particular, these plug-in type connecting rods are extremely precise because they must satisfy both contradictory functions that they are easy to insert and hard to pull out. In order to prevent the sliding surface from being damaged, it is an iron rule that the twist in the circumferential direction for fine adjustment of the position is never performed. Therefore, once the position is displaced, it must be reinserted without fail. .

[0005] In addition, these operations are not necessarily performed during the daytime when the vision is effective, but may be performed in the early morning or at sunset, or when the vision is almost ineffective as in night fishing. . Under such bad conditions, it is extremely difficult to match the lines of the reel and the guide ring in a groping state.

[0006] Further, in such a connecting rod of this kind, a poorly formed product, or if used for a long period of time, causes a joint to come off when used, so-called cut-out. Regarding this cut-out, if the joint is firmly inserted, the cut-out can certainly be prevented, but it is difficult to pull out smoothly when it is desired to pull out.

On the other hand, if the insertion is loosened to make it easy to pull out, the rod comes off accidentally during use as described above. Surprisingly, the plug-in type connecting rod has a structure that is difficult to handle, both for the user and from the standpoint of the manufacturer. As mentioned above,
Conventional plug-in type connecting rods have many problems in terms of handling and durability.

The present invention has been made to solve the above-mentioned problems in the conventional connecting rod.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings, including the operation thereof.
FIG. 1 shows an overall view of the connecting rod of the present invention, and FIG. 2 shows a state before the former rod is attached to the former rod (removal of the reel). FIG. 3 is an internal structural view showing a partially cut-out part of a joint nut between the former rod and the former rod. The connecting rod is composed of a former rod 1B and a former rod 1A. Former rod 1 is former rod grip part 1
2, a reel mounting part 10, and a fastening screw part 7. The front rod 1A includes a connecting nut 5, a connecting nut support 4 (see FIGS. 4 and 5), a reinforcing core 6, a front rod grip 3, and a rod 2 having a guide ring. Is provided.

The original rod 1B is composed of the original rod grip portion 12, the reel mounting portion 10, and the fastening screw portion 7 as described above, but the original rod grip portion 12 is not necessarily required. However, when attaching the former rod grip part 12,
It goes without saying that any shape and any length can be attached. The reel mounting unit 10
A reel fixing portion 11 is provided on the rear side, and the reel 1 is fixed as a pair with a set ring 9 provided in front.

The set ring 9 is loosely fitted in the vicinity of the base of the screwing portion 7 for tightening, and the upper end thereof is pressed by the tightening nut 8 for the reel toward the original rod grip portion 12. That is, as shown in the cross-sectional views of FIGS. 4 and 5, the back foot portion of the reel (not shown) is pushed into the reel fixing portion and is placed on the reel mounting portion 10, and then the tightening nut 8 for the reel is rotated to set the reel. The structure is such that the tip of the front foot portion 15 is pressed by the tapered portion 91 on the inner surface of the ring 9 and the set ring 9 is pressed and fixed.

In the same figure, the fastening screw 7
Is attached to the tip of the reel attachment portion 10 and the inside thereof is hollow to form a core fitting portion 72. The core 6 for reinforcing the former pole is inserted into the core fitting portion 72. As described above, the fastening screw portion 7 penetrates and holds the set ring 9 and the joining nut 5.

Next, the former pole 1 will be described with reference to FIGS. A joint nut support 4 is attached to the rear end of the front rod grip 3. The joint nut support portion 4 is formed with a hollow inside, and a fitting portion 44 of a fastening screw portion is formed. The fitting portion 44 is inserted while the fastening screw portion 7 is in contact therewith. Therefore, the diameter of the fitting portion 44 is set substantially equal to the outer diameter of the fastening screw portion 7. Joint nut support 4
Has a guide rail 45 in the rod axis direction on the inner peripheral surface thereof, and a joining nut locking claw 41 extending from the tip thereof is formed. The joining nut locking claw 41 has a tapered portion 42 at the upper end, and has a fitting groove 43 having a rectangular cross section immediately below the tapered portion 42.

The joint nut 5 is formed separately, and attached by being fitted to the joint nut support 4. Although the inside is a screw surface, a rotation guide groove 51 having a rectangular cross section is formed in the inner peripheral portion of the end portion, and a taper portion 52 to be fitted to the outside is formed at a wide angle continuously. The minimum inner diameter portion of the fitting taper portion 52 is formed smaller than the maximum outer diameter portion of the joining nut locking claw 41.

As described above, it is necessary for the fitting taper portion 52 having a small inner diameter to pass through the joint nut locking claw 41 having a large outer diameter. Therefore, the material of the joint nut support portion 4 is, for example, plastic. It is preferable to do so. Once the joint nut 5 is press-fitted to the joint nut locking claw 41, there is no possibility that the joint nut 5 will come off with normal external force. When the joining nut 5 is fitted to the joining nut locking pawl 41, the tapered portions of the two slide with each other to assist the fitting.

Further, the width of the rotation guide groove 51 of the joint nut 5 is made slightly larger than the length of the joint nut locking claw 41, and similarly, the width of the fitting groove 43 of the joint nut support 4 is reduced. The width is set slightly larger than the width of the tapered portion 52 to which the joining nut 5 is fitted. By setting a certain clearance in this way, the fitting nut 5 after fitting can be moved back and forth in the rod axis direction. By giving a degree of freedom to the movement of the joining nut in this way, the joining operation is facilitated as described later.

A reinforcing core 6 extends from the rear end of the front rod grip 3 through the axial center of the joint nut support 4. When the reinforcing core 6 is connected to the rod, the reinforcing core 6 is inserted into the core fitting portion 72 of the tightening screw portion 7, and serves to reinforce the connecting portion when used. Further, by using the reinforcing core 6, when the rods are joined, the alignment between the former rod 1B and the former rod 1A and the position in the circumferential direction can be easily performed.

An operation procedure for actually connecting the connecting rod having the above-described mounting structure will be described below. Now, for example, the original rod 1B is grasped with the left hand and the former rod grip part 3 of the former rod 1A is grasped with the right hand, and the reinforcing core 6 of the former rod 1A is screwed into the core fitting portion 7 of the screwing portion 7. 72, and until the end of the fastening screw portion 7 comes into contact with the inlet of the joint nut 5 (see FIG. 4). At this time, for the right hand, the middle finger, the ring finger and the little finger are used for the former pole grip 3
And hold the joint nut 5 between the thumb and the index finger. And the joint nut 5 butted against the fastening screw portion 7
The original rod 1B and the former rod 1A while rotating the thumb with the forefinger.
Press lightly with both hands in the direction of the rod axis to help the screwing progress with each other.

When it is considered that the tip of the fastening screw 7 has reached the tip of the guide rail 45 of the joint nut support 4, both hands are moved back and forth slightly in the rod axis direction. As described above, since the rotation guide groove 51 of the joint nut 5 is fitted to the joint nut locking claw 41 with an appropriate clearance in the axial direction thereof, Each time the front end portion and the front end portion of the guide rail 45 are moved back and forth, they squeeze, giving a sound and a certain touch.

Here, when the former rod 1B and the former rod 1A are pressed and rotated in the opposite directions, a feeling that the tip of the guide rail 45 coincides with the guide vertical groove 71 can be obtained. At this time, the leading end of the guide rail 45 can slightly enter the guide longitudinal groove 71 by the clearance described above. In this state, when the joining nut 5 is tightened, the fastening screw portion 7 is inserted while being in contact with the fitting portion 44, and the joining nut abuts the joining nut support portion to complete the joining operation ( (See FIG. 5). When the fastening screw portion 7 and the joining nut 5 are first butted together, the line between the reel 13 and the guide ring 21 should be screwed together as much as possible, if possible. Is more easily matched.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. The former rod grip portion 12 and the fastening screwing portion 7 of the former rod 1B may be formed integrally or may be formed separately and combined. This also applies to the relationship between the joint nut support portion 4 and the front rod grip portion 3.

The original rod grip portion 12 and the former rod grip portion 3 may have both of them or may have only one of them. Further, the cross-sectional shapes of the rotation guide groove 51 of the joint nut 5 and the fitting groove 43 of the joint nut support 4 do not necessarily have to be rectangular, but may be any as long as they fulfill their functions. Furthermore, the material used for the connecting rod is not limited to the material, and can be appropriately selected.

[0037]

The present invention is configured as described above and has the following effects. That is, the connecting rod of the present invention has a configuration in which the former rod and the former rod are screwed,
An extremely convenient and durable connecting rod was obtained, in which the connecting operation was ensured, and no knotting occurred during use.

When the main rod and the front rod are joined, a structure is adopted in which the guide vertical groove and the guide rail are fitted and joined, so that the positional relationship in the circumferential direction is fixed and secured, and the reel and the guide ring are aligned with each other. There is no need to make adjustments so that the joints are located in the same position, and the joining work is extremely easy.

Since the fastening screw portion of the original rod is used for both the reel fastening function and the splicing function, the structure of the splicing rod is simple and easy to handle.

By adopting a structure in which the reinforcing core is inserted into the fastening screw portion, sufficient strength can be ensured, and the joining operation becomes very easy as a guide for joining.

The connecting nut has a structure in which it is fitted to the connecting nut locking claw of the connecting nut support portion, so that when connecting, the original rod and the former rod are fixed, and the connecting nut is attached. It is extremely easy to handle only by rotating only the shaft.
