Description

  The present invention relates to a fishing rod, and more particularly to a fishing rod having a rod unit that can be connected regardless of the order. According to another aspect of the present invention, the present invention relates to a fishing rod provided with a rod unit in which gas is injected into a sealed internal space to increase elasticity.

  A conventional fishing rod has a structure in which a plurality of rod units can be detachably connected by an assembly structure (hereinafter referred to as an “assembled type fishing rod”), and each rod unit is connected to adjacent rod units like a telescope. It is roughly classified into a fishing rod having a structure that can be inserted into the inner diameter of the storage and stored and deployed when used (hereinafter referred to as “expandable fishing rod”).

  The assembly type fishing rod is assembled by sequentially inserting one end portion of a rod unit having a small diameter into one end portion of the rod unit having a large diameter so as to be detachable. In addition, each heel unit has a tapered shape in which the diameter at one end decreases in the longitudinal direction. That is, in the assembly type fishing rod, the order of assembling each rod unit is determined. Therefore, the assembly type fishing rod cannot change the length of the fishing rod determined at the time of manufacture, and it is necessary to prepare a plurality of fishing rods in case the length of the fishing rod needs to be changed depending on the fishing place. . In addition, if the attachment of the connecting part of the heel unit is loosened during use, the connecting part may be removed.

  Since the length of the unfolding type fishing rod is also determined at the time of manufacture, a plurality of fishing rods must be prepared for the case where it is necessary to change the length of the fishing rod depending on the fishing place, There was a drawback that the outer diameter of the heel unit provided with the handle was increased and the weight was increased.

  In addition, the inner diameter of the rod unit increases in the order of attachment to the rod unit provided with the handle in both the assembly type and the unfolded type fishing rod, and the length of the rod unit is shortened for easy portability. In this case, the outer diameter of the heel unit provided with the handle becomes too large, resulting in a drawback that the weight becomes heavy. Also, the inside of the hollow formed rod unit communicates, and when the fishing rod is immersed in water, the water penetrates into the inside, the weight of the fishing rod becomes heavy, and the elasticity decreases, If the fishing rod is missed or part of the fishing rod is removed, there is a drawback that it sinks into the water.

  The present invention has been made in view of the above problems, and according to one aspect of the present invention, a plurality of rod units can be connected regardless of the order, and can be assembled and used at a desired length depending on where to fish. The purpose is to provide fishing rods. The said heel unit is equipped with the means for attaching to both ends so that removal is possible, and it can prevent that the heel unit assembled when using is removed.

  Moreover, both ends of the dredging unit are sealed, so that it is possible to prevent water from penetrating inside, and it is possible to improve elasticity when gas is injected.

  In addition, the present invention provides a fishing rod having a rod unit in which both ends are sealed so that water does not penetrate into the fishing rod and does not sink even when immersed in water, and gas is injected therein. The other purpose is to provide. In particular, when a gas lighter than air such as helium is injected, the other object is to provide a fishing rod that can adjust the elasticity of the fishing rod by reducing the weight of the fishing rod by buoyancy and adjusting the pressure of the injected gas. .

  In order to achieve the above object, a fishing rod having a rod unit that can be detachably connected regardless of the order according to one aspect of the present invention includes a plurality of rods that have one end inserted into adjacent rod units and are detachably connected in order. In the fishing rod provided with the hollow cylindrical rod unit, at least one rod unit among the plurality of rod units is fixed by inserting a basic tube having a constant inner diameter and one side into one end of the basic tube. The other side is detachably inserted in the adjacent heel unit and includes a connecting pipe having a constant outer diameter. The scissor unit includes a locking tool (or a coupling tool) inserted into the inner surface of the basic pipe so as not to be removed when assembled and used, and a coupling tool (or a fixing tool fixed to the end of the connection pipe). And a locking tool).

  When fixing the locking tool to the inner peripheral surface of the basic pipe and fixing the coupling tool to the end of the connecting pipe, the locking tool has a hollow cylindrical shape and extends from the end in the longitudinal direction of the fishing rod. A guide channel and a constraining channel extending in the circumferential direction from the guide channel are provided on the inner peripheral surface, and the coupling tool has a shape that can be inserted into the hollow of the locking tool, and extends in the radial direction of the fishing rod. A restraining protrusion is formed that protrudes to have a height between the inner diameter and the outer diameter of the locking tool. When the coupler is fixed to the inner peripheral surface of the basic pipe and the locking tool is fixed to the end of the connecting pipe, the coupler has a hollow cylindrical shape, and radially extends toward the center of the fishing rod on the inner peripheral surface. A restraining projection protruding at a predetermined height is formed, and the locking tool is a cylindrical shape that can be inserted into the hollow of the coupling tool, and extends from the end in the longitudinal direction of the fishing rod; A constraining channel extending in the circumferential direction from the guide channel is provided on the outer peripheral surface, and the guide channel and the constraining channel have a depth deeper than the height of the constraining protrusion.

Assembling is possible regardless of the assembly order. Further, the fishing rod of the present invention is detachably attached to the adjacent rod unit by means of a locking member and a coupling member fixed to both ends of the rod unit, and is not removed when used.

  In addition, a fishing rod having a rod unit that can be removably connected regardless of the order according to the present invention connects the outer diameter of the basic tube from the side where the connecting tube is not attached in order to reinforce the strength of the rod unit. You may make it reduce, so that it goes to the side in which the pipe | tube was attached.
