BACKGROUND OF THE INVENTION
The present invention relates to a fixed holding structure positioning component, more particularly to those capable of removing the positioning component for fixing and holding the stud bolts easily.
[0002]
[Prior art]
Conventionally, in order to position and fix a component at a designed position, a stud bolt is installed at the mounting position, and a fixing holder fixed to the positioning component is engaged and fixed to a screw portion of the stud bolt. Thus, generally, the positioning component is held and fixed at the mounting position.
[0003]
For holding and fixing this type of positioning component, for example, as shown in FIG. 7, a linear body such as a vehicle wire harness is bound by the band portion 2 of the binding band 1 and is integrally formed with the binding band 1. A fixing holder structure configured to engage and fix the head portion 3 being engaged with the stud bolt 7 shown in FIG. 8 is conceivable.
[0004]
In this fixed holder structure, as shown in FIG. 8A, when the wire harness 9 bound by the binding band 1 is attached to a design position such as the vehicle panel 8 on which the stud bolt 7 is installed, the binding band 1 A stud bolt 7 is inserted into the head portion 3 to be housed and fixed. At this time, as shown in FIG. 8 (b), the head portion 3 has the elastic protrusion 4b of the elastic deformation portion 4 formed by cutting out the outer peripheral portion of the interior hole, while the engaging protrusion 4b at the tip thereof is a stud. The wire harness 9 can be fixedly held at the mounting position of the vehicle panel 8 by engaging the threaded portion (groove) of the bolt 7 and locking the movement in the return direction and fixing the bolt 7 so that it cannot be pulled out.
[0005]
[Problems to be solved by the invention]
However, in such a conventional fixing and holding, since the head portion 3 cannot be pulled out from the stud bolt 7 once the head portion 3 of the binding band 1 is fixed to the stud bolt 7, the wire harness In order to remove 9 from the vehicle panel 8, the band part 2 of the binding band 1 must be cut using a tool or the like, or the head part 3 must be destroyed. For this reason, it is impossible to temporarily fix the wire harness 9 and perform a wiring state test or the like, and it is also impossible to recycle the wire harness 9 while being bound by the binding band 1. Further, the binding band 1 obtained by cutting the band portion 2 remains on the vehicle panel 8 side, and there is a problem that the burden of removing it is heavy.
[0006]
Further, in the case of the vehicle panel 8 in which the wire harness 9 is routed, for example, there are many places with extremely poor workability such as the driver's seat feet and the engine room and the like, and both the fixing and holding work and the releasing work are simple and easy. There is a demand for a reliable structure.
[0007]
Therefore, the present invention can easily fix and hold the positioning component at the position where the stud bolt is installed, and can easily release the fixing and holding to realize fixing and recycling again. an object of the present invention is to provide a holding structure.
[0008]

A holding member that fixes and holds the component in the mounting position, and the fixing member is formed in a tool mounting shape on the opposite side of the interior portion that houses the stud bolt, and is between the interior portion and the tool mounting portion. While the holding member has a groove-shaped portion extending in the circumferential direction, the groove-shaped portion of the fixing member is positioned in the opening, and the holding member is faced to both the interior portion and the tool mounting portion. It has a plate-shaped part that holds it rotatably, and the plate-shaped part has a structure that can be divided and separated from each other. It is configured to be openable to Than it is.
In the present invention, the fixing member can be rotated in the circumferential direction with respect to the threaded portion of the stud bolt without changing the posture of the positioning component and the holding member while being connected to the holding member fixed to the positioning component. The threaded portion can be sent in the pulling direction to be detached from the stud bolt. Therefore, the positioning component can be easily removed from the mounting position without destroying the fixing member or the holding member.
Further, after positioning the groove-shaped portion between the interior portion of the fixing member and the tool mounting portion in the opening portion in a state where the plate-shaped portion is divided and opened to the outside, the opening portion is closed, The plate-shaped portion faces the interior portion and the tool mounting portion, and can be connected to a fixing member that is fixed to the stud bolt while allowing relative rotation.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. Figures 1-5 illustrates the basic structure of a fixed holding structure of position-decided Me component. In this basic structure , the same components as those in the prior art described with reference to FIGS.
[0015]
First, the configuration will be described.
[0016]
In FIG. 1, reference numeral 10 denotes a band clip (fixed holding tool). The band clip 10 is wound around a wire harness (positioning part) 9 attached to a design position of the vehicle panel 8 and is engaged and locked to the locking portion 13. The band portion (holding member) 2 that binds (fixes) the wire harness 9 and the stud bolt 7 shown in FIG. The head portion (fixing member) 23 to be fixed is formed separately from a resin material that expresses a certain elastic force, and the band portion 2 of this basic structure is formed in the circumferential direction of the screw portion of the stud bolt 7. By connecting the head part 23 to the locking part 13 side in a rotatable manner, the wire harness 9 that is bound is fixedly held on the stud bolt 7 to which the head part 23 is fixed. The band portion 2 may be engaged and locked with the locking portion 13 by a general method. For example, the engaging claw is engaged with a continuous groove (not shown) of the band portion 2 inserted through the locking hole 13a. The movement in the returning direction is locked and the wire harness 9 is bound and held and fixed.
[0017]
The head portion 23 is locked to move in the returning direction when the engaging protrusion 4b at the tip of the elastic portion 4a of the elastic deformation portion 4 expanded and returned by the inserted stud bolt 7 is engaged with the screw portion. An inner portion 24 that is fixed so that it cannot be pulled out, a groove-shaped portion 25 that has a smaller diameter than the inner portion 24 and extends in the circumferential direction, and a hexagonal nut shape that is larger in diameter than the groove-shaped portion 25. And a tool mounting portion 26 located on the tip end side of the stud bolt 7.
[0018]
On the other hand, the band portion 2 is formed with a plate-shaped portion 32 extending in a plate shape with a thickness of about the groove width of the groove-shaped portion 25 of the head portion 23 on the side away from the locking portion 13. The plate-shaped portion 32 is continuous with an opening 34 having a smaller diameter than the interior portion 24 and the tool mounting portion 26 of the head portion 23 and a larger diameter than the groove-shaped portion 25, and the same width as the opening diameter of the opening 34. Thus, an open space portion 33 that opens (communicates) the opening 34 to the outside is formed, and a protrusion 35 that narrows the communication width is formed at the opposing portion that defines the open space portion 33. .
[0019]
Therefore, the head 23 is pressed against the inclined surface of the protrusion 35 by positioning the groove-shaped portion 25 in the open space 33 of the plate-shaped portion 32 of the band portion 2 and pushing it in the direction of the opening 34. Accordingly, the groove-shaped portion 25 can be positioned in the opening 34 by elastically deforming so as to widen the gap between both sides of the open space 33 of the plate-shaped portion 32, and the vertical wall of the projection 35 of the plate-shaped portion 32 that has been elastically restored. Thus, it is possible to connect the opening 34 so as not to be detached. In this state, the head portion 23 and the band portion 2 are connected to each other so that the plate-shaped portion 32 positioned in the groove-shaped portion 25 faces both the interior portion 24 and the tool mounting portion 26 so as to be relatively rotatable. Can be maintained.
[0020]
The plate-shaped portion 32 is reinforced by forming a rib 32a between the plate-shaped portion 32 and the locking portion 13 and forming a frame portion 32b.

[0022]
First, the band part 2 and the head part 23 are prepared. The band part 2 is wound around a predetermined position of the wire harness 9 and engaged and locked by the locking part 13, while the head part 23 is a wire. The stud bolt 7 installed at the mounting position of the vehicle panel 8 located on the wiring path of the harness 9 is inserted into the interior portion 24 and engaged and locked with the threaded portion, so that it cannot be pulled out.
[0023]
Next, while routing the wire harness 9 on the vehicle panel 8, the groove-shaped portion 25 of the head portion 23 is pushed into the opening 34 of the plate-shaped portion 32 of the band portion 2 to project the interior portion 24 and the tool mounting portion 26. 35 and is connected so as not to be disengaged.
[0024]
Therefore, the wire harness 9 can be fixed and held at the mounting position (routing position) on the vehicle panel 8 by the same easy work as in the prior art without screwing.
[0025]
When removing the wire harness 9 that is fixed and held for dismantling the vehicle, or when removing the wire harness 9 that is temporarily fixed for a wiring state test or the like, FIG. 4 and FIG. As described above, the tool mounting portion 26 of the head portion 23 is mounted in a hexagonal hole 61 of a general hexagon wrench (tool) 50 while being rotatably connected to the plate-shaped portion 32 of the band portion 2. By engaging and rotating in a direction away from the threaded portion of the stud bolt 7, the engaging projection 4b of the head portion 23 that engages with the threaded portion is guided in the pulling direction to release the engagement, and the stud bolt 7 to release the wire harness 9 from the vehicle panel 8.
[0026]
Therefore, the band clip 10 can be removed from the stud bolt 7 and the wire harness 9 can be removed from the vehicle panel 8 without cutting or destroying the band part 2 or the head part 23 or leaving the head part 23. it can.
[0027]
