Description
Technical field
The present invention relates to be provided with the extraction pole of auxiliary section; This auxiliary section can be accommodated between the state that the inner state of big footpath side rod body and path side rod body extract out from the side rod body of big footpath at the path side rod body switches; And it can make this pole keep extracting out elongation state.
Background technology
The structure of above-mentioned auxiliary section is following: the inclined-plane that has formed mutual crimping at the outer peripheral face and the inner peripheral surface of the pole anterior end of big footpath side rod body of the pole tail side end of path side rod body.Keep the elongation state of path side rod body through the extruding between this inclined-plane.
Adopting this structure and when this extruding contact condition keeps the elongation state of path side rod body down,, so-called set state will occur on compressive plane if existence such as moisture is arranged.That is to say,,, just get it right that it applies common strength, also can not remove this elongation state because two inclined-planes at extruding position are in powerful then state even want the path side rod body is changed to contraction state from elongation state.
Therefore, owing to can not pack up the fishing gear in this case, can cause trouble at last.
Consider this point; Disclose in the patent documentation 1 (pass the imperial examinations No. 2569413 (paragraph (0009) (0012), Fig. 1) in fact) on the outer peripheral face as the rear end of the path pole pipe of path side rod body and be provided with kick, this kick can be crimped on the inner surface as the big footpath pole pipe front end of big footpath side rod body and play the effect of not allowing the drainage that has moisture between surfaces externally and internally.
If there is moisture in the auxiliary section, though can impel the generation of set phenomenon really, not thus much one of the reason that the set phenomenon produces.That is to say that as stated, the inclination inner peripheral surface of big footpath, auxiliary section side rod body pole front end and the inclination outer peripheral face of path side rod body pole tail side are in squeezed state and form.When two inclined-planes were in crimped status, big neck side rod body pole front opening received the power that makes its opening dimension, the power that path side rod body pole tail side end is shunk, and two inclined-planes are in the elastic deformation crimped status.Therefore, owing to be in the elastic deformation crimped status,, turn back to original state and can compare difficulty if crimping strength is bigger.
This squeezed state forms through kick is crimped on the opposite side inclined plane, and prior art is no exception.Because compounding practice can be with the powerful fastening of kick and opposite side inclined plane through the short time short stroke; Though thus with do not form comparing of kick; More difficult generation set phenomenon, but can not remove the moment crimped status when carrying out compounding practice, need improve the auxiliary section this.
Summary of the invention
The object of the present invention is to provide a kind of body of fishing rod, this pole body can be eliminated above-mentioned defective on the one hand, alleviates the burden in the manufacturing, can avoid the generation of set phenomenon on the other hand.
The architectural feature that technical scheme 1 of the present invention relates to is following: be formed with the auxiliary section that can make the big relatively footpath of path side rod body side rod body keep elongation state; Simultaneously, the formation of this auxiliary section comprises that straight-tube shape portion is with prominent facial, wherein; Straight-tube shape portion forms in the side of path side rod body with big footpath side rod body; And contact-making surface is certain diameter, prominent facial forms in path side rod body other sides with big footpath side rod body, contacts with the contact-making surface of above-mentioned straight-tube shape portion.Be made up of the preforming material that has soaked into resin among the reinforcing fiber crowd who disposes at the axis direction along the pole body with the contacted superficial layer of above-mentioned straight-tube shape portion of above-mentioned prominent face, its action effect is following.
Through form a straight-tube shape portion in the auxiliary section; Even carry out fierce stretched operation, face and this straight-tube shape portion state of contact because appearance is dashed forward, mitigation so operating physical force can become because of the operation resistance that dash forward face and straight-tube shape portion produce; Simultaneously because the existence of straight-tube shape portion; Keep certain operation resistance, this state can let the fishing people recognize that the situation that precepitates into the set state is less.
And, because the prominent face that conduct and straight-tube shape portion contacted opposite side have adopted preforming material to make, and compare, more abrasion resisting etc. with the kick of formations such as resin.
But, and not only constitute prominently facial,, therefore arrange by circumferencial direction and compare flexural deformation easily with reinforcing fiber because the orientation of reinforcing fiber is along the direction setting of rod axis with the preforming material that contains reinforcing fiber.Such as, when the section of pole is deformed under the elliptoid situation, when reinforcing fiber was pressed the circumferencial direction configuration, reinforcing fiber will be brought into play its resistance and stop distortion, makes section be difficult to deform.Relative therewith, along the reinforcing fiber of rod axis direction configuration, under the situation of ellipticity distortion, deformation drag is big when pressing the circumferencial direction configuration unlike reinforcing fiber at section.This means prominent face portion easily in radial direction generation deflection, therefore, prominent facial contact with straight-tube shape portion and when moving, prominent facial what deflection can take place, therefore can avoid strong contact the between prominent face and straight-tube shape portion.Thus, when the path side rod body is pulled out from the side rod body of big footpath, pull out resistance and become more stable.
Therefore; Through to the formation of straight-tube shape portion, will make prominent facial shape into the contacted side of straight-tube shape portion, form prominent facial each side with preforming material and transform; Can prevent the set phenomenon in possible trouble, the operation sense in the time of also compounding practice being improved simultaneously.
The architectural feature that technical scheme 2 of the present invention relates to is following: the circumferencial direction along the pole body forms the aforementioned prominent face in number place, and its action effect is following.
Identical with the action effect of technical scheme 1 of the present invention.In addition, because prominent face is not along the full week setting of circumferencial direction, so when the path side rod body pulled out from the side rod body of big footpath, resistance can be not excessive, and prominent face portion is easily to the radial direction deflection.
Therefore, even some changes directly take place in the inner surface of straight-tube shape portion, prominent facial also can how many changes to the deflection that should directly change generation, so just can keep certain resistance of pulling out.
The architectural feature that technical scheme 3 of the present invention relates to is following: on the inner surface of big footpath side rod body, be formed with conical inclination continuing surface; This inclination continuing surface forms with the mode of the pole front end of the aforementioned straight-tube shape of adjacency portion; And; The conical inclination bearing surface of formation and aforementioned inclination continuing surface butt on the outer peripheral face of aforementioned path side rod body, its action effect is following.
At the terminal of prominent face with the contact condition of straight-tube shape portion, the inclination bearing surface is connected on the inclination continuing surface.That is to say, prominent facial when being in contact condition with straight-tube shape portion, can feel certain enhanced stretch resistance slightly.In the acting process of this certain resistance, when the inclination bearing surface contacted with the inclination continuing surface, resistance will increase suddenly, the fishing people can feel this changes big resistance, thereby learn the terminal location that has arrived stretching.
In view of the above, can prevent stretching transition, stop the set phenomenon to occur.
The architectural feature that technical scheme 4 of the present invention relates to is following: at aforementioned path side rod body outer surface when the pole tail side of aforementioned inclination bearing surface is formed with pole body tail end; Uprightly at the pole tail end place of aforementioned pole body tail end be provided with prominent facially, the external diameter of pole body tail end is arranged to than the external diameter of the pole tail end of inclination bearing surface and the little external diameter of external diameter of aforementioned prominent face.Its action effect is following.
That is to say that the diameter of pole body tail end outer peripheral face is littler than the external diameter or the prominent facial external diameter of the pole tail end of inclination bearing surface, therefore can not contact with straight-tube shape portion and inclination continuing surface.Like this; Under the state that the path side rod body is extracted out from the side rod body of big footpath, till connecting to inclination bearing surface and inclination continuing surface during because the prominent face that only forms at the pole tail end place of pole body tail end contacts with straight-tube shape portion; Even therefore draw direction and rod axis some inclination relatively; Since only through prominent facial distortion just can adjust its when the heeling condition with the situation that contacts of straight-tube shape portion, thus, the operability in the time of can improving draw out operation.
And; The pole body tail end that prominent face is bearing in pole tail end position is a minor diameter, so section coefficient can diminish the reaction force that produces with prominent facial contacted straight-tube shape portion; Make pole body tail end with the splice locations of inclination bearing surface as base end part; Prominent face to be in the pole tail end-side becomes leading section, as cantilever beam, bends, and is prone to make this prominent facial direction generation displacement along the footpath.Therefore, even the diameter dimension change of straight-tube shape portion also can be kept the contact condition of predetermined surface pressure through prominent facial displacement.
The architectural feature that technical scheme 5 of the present invention relates to is following: aforementioned inclination bearing surface and superficial layer between aforementioned pole body tail end are that the preforming material by the reinforcing fiber crowd with edge circumferencial direction configuration vertical with rod axis constitutes, and its action effect is following.
One of the effect that relates to like technical scheme 1 had been explained, the power that receives radial direction at pole made its section under the situation that ellipse changes, and can bring into play resistance along the reinforcing fiber of circumferencial direction configuration and stop distortion, makes the section deformation.
That is to say when the path side rod body is pulled out, to have only prominent face to contact with straight-tube shape portion from the side rod body of big footpath, support that the diameter of this dash forward facial pole body tail end and inclination bearing surface is littler than prominent face, it can be by the inner surface support of big footpath side rod body.
So; Though the structure of pole body tail end bends easily; But inclination bearing surface and pole body tail end have adopted the configuration structure of the reinforcing fiber of very difficult generation deformation; Can suppress to support the reduction significantly of prominent facial function, such structure is to being effective when the path side rod body is pulled out from the side rod body of big footpath.
The architectural feature that technical scheme 6 of the present invention relates to is following: the intermediate layer of inclination bearing surface and pole body tail end is overlapping following two kinds of preforming materials and constituting; Promptly; Contain reinforcing fiber crowd's the preforming material of the direction aligned configuration at relative rod axis regulation inclination angle, and contain the preforming material that aforementioned rod axis is the reinforcing fiber crowd of symmetry status configuration with the reinforcing fiber faciation of aforementioned preforming material.Its action effect is following.
Of technical scheme 6; Pole tail end at pole body tail end is provided with prominent facial; From supporting this prominent facial necessity, be difficult for taking place deformation in order to make inclination bearing surface and pole body tail end, use the preforming material that disposes reinforcing fiber along circumferencial direction at its superficial layer.On the other hand; Owing to the intermediate layer of inclination bearing surface and pole body tail end is by overlapping reinforcing fiber crowd wherein to be formed along the preforming material of heeling condition configuration each other; Even the shear strength on acting on inclination bearing surface or pole body tail end; Because its tension force of reinforcement feature on the layer that mediates performance, can stop the propagation of bigger plastic deformation etc., and can stop peeling off between outside layer and la m.
