Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rod body constituting a fishing rod used for fishing.
[0002]
[Prior art]
In order to reduce the strength and weight in recent years, a cylindrical rod constituting the fishing rod is made of a sheet or tape-like fiber reinforced resin (prepreg) in which a synthetic resin is impregnated with carbon fiber or glass fiber. This casing is manufactured by applying a release material or the like to the peripheral surface of a cylindrical core material with a tapered taper, winding an arbitrary number of prepregs while applying pressure thereto, and firing the prepreg in a furnace. Is done.
[0003]
By the way, a plug member called a butt plug is detachably fitted in the end side end portion of the main rod located on the most base side in the conventional case. For example, when disassembling a swing type fishing rod into individual rods, the tail plug is removed from the main rod, and the rod on the tip side is inserted into and removed from the rod side. Many conventional fishing rods are of a type in which a female screw member having a thread on the inner peripheral surface is separately manufactured and then fitted and fixed to the base end portion of the main rod, and the end plug is detachably screwed here. There were many things. However, such a fishing rod that fixes a separately produced female screw member increases the number of manufactured parts and the manufacturing process. Therefore, in recent years, a type in which a thread groove is directly cut on the inner peripheral surface of the heel side of the mortar and a bottom plug is screwed therein has appeared on the market.
[0004]
[Problems to be solved by the invention]
As described above, when a thread is directly cut and formed on the inner peripheral surface of the base side end portion of the base rod, there is a possibility that the fibers of the fiber reinforced resin constituting the casing may be peeled off. That is, in general, many cases are formed by firing the prepreg as described above. Therefore, when the inner peripheral surface of such a case is shaved to form a thread groove, a part of the reinforcing fiber is formed from the shaved part. There is a risk that the reinforcing fiber is cut at the exposed or shaved portion and the reinforcing fiber is peeled off. Such peeling of the reinforcing fibers hinders the smooth desorption of the bottom plug.
[0005]
In addition, the problem of screw loosening cannot be excluded with a screw-type bottom plug. Even if the bottom plug system is set or a rubber ring for locking is placed at the end of the main shaft together with the bottom plug, it cannot be said that it is sufficient to prevent the locking, and a device for further locking is required. It is done.
An object of the present invention is to provide a fishing rod having a bottom plug that is less likely to loosen and can be easily attached and detached.
[0006]
[Means for Solving the Problems]
The fishing rod of the invention 1 is a fishing rod used for fishing, and has a trumpet-shaped portion in which the outer diameter and the inner diameter are partially enlarged in the axial range on the rod side, and the diameter of the rod is increased. a rod body which is formed of fiber reinforced resin and having a directly machined dug screw groove on Saomoto end inner peripheral surface that is an epoxy-based paint applied to the screw groove, removably to said screw groove And a butt plug having a male thread portion that is screwed onto the butt.
[0007]
In this fishing rod, the bottom plug is detachably attached to the rod body by screwing the male screw portion into the thread groove on the inner peripheral surface of the rod side end portion of the rod body. The thread groove of the housing is directly cut in the peripheral surface of the housing, and the thread groove can be formed relatively easily. An epoxy-based paint is applied to the thread groove, and the reinforcing fiber is prevented from peeling from the groove formed by cutting the inner peripheral surface of the casing. In addition, the thread groove is carved in the inner peripheral surface of the housing, and the degree of adhesion of the epoxy resin to the inner peripheral surface of the housing can be improved without performing a roughening process on the inner peripheral surface, and the coating process is also performed. It is relatively easy.
[0008]
The fishing rod of the invention 2 is the fishing rod of the invention 1, and the epoxy paint is an epoxy resin diluted with a clearing agent to 200 to 500%.
By applying the diluted epoxy paint diluted to such a predetermined range, it is possible to smoothly apply the epoxy paint to the screw portion. Moreover, when it becomes a rare paint exceeding 500%, it will become difficult to acquire sufficient effect for peeling prevention.
[0009]
The fishing rod of the invention 3 is the fishing rod of the invention 1 or 2, wherein a rubber-based paint is further applied to the surface to which the epoxy-based paint is applied.
In this fishing rod, the rubber-based paint further applied to the surface of the epoxy-based paint serves as a cushion, and unnecessary rotation of the bottom plug screwed here is suppressed to prevent loosening.
[0010]
