Description

  The present invention relates to a joining processing tool used for abutting and joining (joining) a male member and a female member, which are joining means attached so as to be able to face a predetermined object to be processed. The present invention relates to a bonding processing tool suitable for application to a winding tool (object to be processed) wound around a long object (object to be wound) such as an electric wire.

  A bird harm prevention tool which is an example of a conventional wrapping tool is described in Patent Document 1. This bird damage prevention tool is used to prevent bird dropping damage to a long object such as an electric wire, and is a flat plate member made of rubber or soft synthetic resin having a horizontally long rectangular shape. And a plurality of needle-like bodies protruding in a dense state from the surface side of the flat plate-like member.

  Such a bird damage prevention device is curved so as to wrap the electric wire in a state where the back surface side of the flat plate member is along the electric wire, and subsequently, the opposite edge portions are joined to each other via the joining means. Attached to the wire.

  By attaching the bird damage prevention device to the electric wire, the electric wire is protected by a large number of needles that the bird dislikes over the entire circumference, and reliably prevents the bird from stopping on the electric wire. Can do.

  The joining means includes a first bracket as a male member protruding from one edge of the flat plate member, and a female member protruding from the other edge so as to correspond to the first bracket. The second bracket (not described as a bracket in the cited document 1 is used here for the sake of clarity). The first bracket is provided with a protrusion on the surface facing the second bracket, while the second bracket is provided with a fitting hole for fitting the protrusion at a position corresponding to the protrusion. Yes.

  The protrusion is formed in a bifurcated shape with the tip split into two in the axial direction, and each tip is provided with a return portion that protrudes in the opposite direction.

  The fitting hole is set to be slightly larger than the outer dimension between the forked portions of the protrusion and smaller than the outer dimension between the pair of return portions. Therefore, when the protrusion is pushed into the fitting hole, the pair of return portions interfere with the edges of the fitting hole, respectively, whereby the bifurcated portions are once elastically deformed in a direction approaching each other. And since a pair of return part will return to an original separation state by elastic force, if the edge part of a fitting hole passes, each return part will be locked to the edge part of a fitting hole. Therefore, the above-mentioned bird damage prevention device can be coupled to each other in a detachment preventing state by press-fitting the forked portion of the protrusion into the fitting hole of the second bracket.

JP-A-8-173006

  By the way, conventionally, the operation of inserting the projections as described above into the fitting holes and joining the first and second brackets has been performed manually with a finger after wearing thick insulating gloves. It is common to use a commercially available tool such as a pliers or a flat-blade screwdriver.

  However, manual work with thick gloves not only does not move the fingertips as expected, but manual work puts a large force on the fingertips, and it can not work for a long time due to hand fatigue, so workability Has the problem of being extremely inferior.

  On the other hand, when a tool such as a commercially available pliers or a flat-blade screwdriver is used, a large force as in the case of using only fingers is not required, and workability is improved correspondingly. However, since the commercially available tool has a structure in which the object is simply sandwiched by the bifurcated operation portion, the protrusion provided on the flexible first bracket made of rubber or soft synthetic resin, It is difficult to stably perform a complex work such as inserting into a fitting hole drilled in the second bracket made of the same material and locking it at the return portion with the tool, resulting in poor workability. Has the problem.

  The present invention has been made in order to solve the conventional problems, and is used for easily joining a female member and a male member attached to a predetermined object to be processed. An object of the present invention is to provide a joining processing tool capable of improving workability.

  The invention according to claim 1 includes a pair of gripping portions for gripping and a pair of operation portions extending from the tip of each gripping portion, and a boundary position between the gripping portion and the operation portion is connected. A male member that is pivotally connected to each other around the axis and has a locking projection protruding from a predetermined object to be processed, and a fitting hole into which the locking projection is fitted in a locked state. In the joining processing tool configured to be able to be pressed and clamped by the one and the other operation portions, respectively, the one operation portion has a surface facing the other operation portion. A male member pressing plate is provided, and the other operating portion is provided with a female member pressing plate on a surface facing the one operating portion, and the male member pressing plate projects to press the male member. One first pressing portion is provided, and the female member pressing plate includes the female portion. Two second pressing portions projecting to press are provided, and the male and female members are prevented from coming off by a three-point pressing process by the one first pressing portion and the two second pressing portions. It is comprised so that it may be performed.

  According to such a configuration, when the male and female members are prevented from being separated from each other by using the joining processing tool, first, the first and female members of the pair of operation portions are arranged in a state where the opposing surfaces of the male and female members are brought close to each other. The male and female members are sandwiched between the pressing plates. At this time, the male member pressing plate is applied to the male member, and the female member pressing plate is applied to the female member. By firmly grasping the pair of gripping parts gripped in this state, the first and female member pressing plates are rotated in the direction approaching each other around the connecting shaft, whereby the male and female members are brought into contact with each other. Touched and pressed.

  The male and female members have one first pressing portion with which a portion corresponding to the locking protrusion of the male member abuts, and two second with which a portion corresponding to the fitting hole of the female member abuts. Since three points are pressed by the pressing portion, the locking projection and each point are reliably brought into contact with the male and female members, thereby realizing a stable pressing process.

  In particular, since the first pressing portion is in contact with the portion of the male member corresponding to the locking protrusion, the pressing force generated by operating the grip portion can be reliably transmitted to the locking protrusion.

  In addition, since the state of the fitting hole is stabilized by bringing the two second pressing parts into contact with the female member in a state of straddling the fitting hole, the locking protrusion is adjusted by operating the gripping part. It can be easily fitted into the fitting hole.

  According to a second aspect of the present invention, in the state where the first pressing portion is made to correspond to the locking projection of the male member, the two second pressing portions are substantially left and right with reference to the fitting hole of the female member. The installation positions of the first and second pressing portions are set so as to face the target position, and the locking protrusions of the male member are inserted into the female member by pressing and holding the first pressing portion and the second pressing portion. It is configured to be fitted into the fitting hole.

  According to such a configuration, even when the male and female members are flexible, such as rubber or soft synthetic resin, the two second pressing portions straddle the fitting hole so that the fitting is performed. Since the shape retaining property of the hole is ensured, the locking projection can be securely fitted into the fitting hole.

  According to a third aspect of the present invention, in the second aspect of the invention, the first pressing portion presses a male member formed in a forked shape by a pair of one-side split projections from the base end side of the one-side split projection, The second pressing portion presses a female member provided with a retaining piece having a free end as a free end so as to be fitted between the pair of one-side split protrusions across the fitting hole from the retaining piece side. It is comprised so that it may carry out.

  According to such a configuration, when the pair of one-side split projections that are locking projections of the male member are being penetrated through the fitting holes of the female member, the pair of return portions at the tips of the one-side split projections are within the fitting holes. By interfering with the peripheral surface, each piece cracking protrusion is elastically deformed in a direction approaching each other.

  When the pair of return portions protrudes outward from the fitting hole, the pair of elastically deformed one-side split protrusions are restored to the original state, and thereby the pair of return portions are locked to the hole edges of the fitting hole. For this reason, the one-sided protrusion is prevented from coming off from the fitting hole.

  At this time, the retaining piece provided on the female member is pushed between the pair of return portions, so that the pair of return portions are elastically deformed in a direction approaching each other so as to come out of the fitting hole. The occurrence of inconvenience is reliably prevented.

  A fourth aspect of the present invention is the invention according to any one of the first to third aspects, wherein the first pressing portion protrudes from the male member pressing plate corresponding to the locking protrusion. It is characterized by being.

  According to this structure, the part corresponding to the latching protrusion of the male member pressing plate of the male member can be intensively pressed by the protruding piece.

  The invention according to claim 5 is the invention according to any one of claims 1 to 3, wherein the first pressing portion has an opposing surface of the male member pressing plate to the female member pressing plate bulged in an arc shape. It is characterized by being formed by the top of the arc-shaped portion.

  According to such a configuration, the male member pressing plate has an arc that bulges toward the female member pressing plate as a whole so that the surface facing the female member pressing plate can press the retaining piece between the pair of one-side split protrusions. Since the male member and the female member are deformed into a circular arc shape, particularly when the male part is formed in a bifurcated shape by a pair of one-sided split projections, the distance between the tip side of the pair of one-sided split projections is widened. can do.

  According to the joining processing tool of the present invention, one first pressing portion with which a portion corresponding to the locking protrusion of the male member is brought into contact with a portion corresponding to the fitting hole of the female member is brought into contact. Since the two second pressing portions are pressed at three points, the male and female members can be pressed in a stable state by the first and second pressing portions, so that the male and female members can be reliably prevented from coming off. Can be applied.

  Then, by connecting the male and female members to each other using the joining processing tool as described above, it is performed by hand as in the prior art, or by using a pliers, a wrench, or the like that is simply held, not supported by three points. Compared to the case, the male and female members of the object to be processed can be easily combined, and this can contribute to the reduction of fatigue during work and the improvement of work efficiency.

A groove 771 is formed. The relief groove 771 is provided when the male member pressing plate 76 and the female member pressing plate 77 hold the joining means 40 so as to penetrate the fitting hole 62 and the rear side of the female bracket 61 (in FIG. 3). This is because the return portion 522 of the one-sided cracking protrusion 521 that has slipped out (upward) is released.

  Then, on both sides of the female member pressing plate 77 with the relief groove 771 sandwiched, the fitting hole 62 is sandwiched and contacts the surface of the female bracket 61 (the upper surface in FIG. 3) without interfering with the fitting hole 62. A pair of pressing strips 772 for contacting and pressing are provided.

  Therefore, in a state where the male and female members 60, 50 of the joining means 40 are pressed and clamped by the male and female pressing plates 77, 76 of the joining processing tool 70, both side portions of the fitting hole 62 in the female side bracket 61 are paired. The portion corresponding to the locking cylinder 52 in the male side bracket 51 is pressed by the pushing protrusion 761 while being pressed by the stripe 772, and by the three-point support by these two pressing stripes 772 and one pushing protrusion 761. Since the male and female brackets 61 and 51 are pressed, even if the joining means 40 is made of rubber or soft synthetic resin, the fitting process of fitting the locking cylinder 52 into the fitting hole 62 is performed. It can be done easily in a short time.

  FIG. 4 is an explanatory diagram for explaining the operation of the welding processing tool 70 according to the first embodiment, and is a schematic cross-sectional view taken along line III-III in FIG. 4A shows a state immediately before the male member 50 and the female member 60 are pressed by the male member pressing plate 76 and the female member pressing plate 77, and FIG. 4B shows the male member 50 and the female member 60. 4C is a state where the locking cylinder 52 is being fitted into the fitting hole 62 by being pressed and clamped by the male member pressing plate 76 and the female member pressing plate 77, FIG. 52 shows a state in which the male member 50 and the female member 60 are prevented from being separated from each other by the engagement of the return portion 522 through the fitting hole 62.

  When the male and female members 60, 50 of the joining means 40 are joined together, first, the grip rod 72 (FIG. 3) of the tool body 71 is operated around the connecting shaft 74, and FIG. 4 (A) and FIG. As shown in A), the male and female pressing plates 77 and 76 are separated from each other, and the male and female members 60 and 50 of the joining means 40 are positioned between the male and female pressing plates 77 and 76 in this state.

  At this time, the pushing protrusion 761 of the male member pressing plate 76 is made to correspond to the locking cylinder 52 of the male member 50, and the pair of pressing strips 772 of the female member pressing plate 77 are connected to the female side on both sides of the fitting hole 62. It is made to correspond to the bracket 61.

  By clamping the pair of gripping rods 72 (FIG. 3) gripped in this state, the male and female pressing plates 77 and 76 are rotated around the connecting shaft 74 (FIG. 3) toward each other. . Accordingly, the pushing protrusion 761 of the male member pressing plate 76 is on the lower surface side in FIG. 4 of the male bracket 51 and presses a position corresponding to the pair of one-side split protrusions 521 and a pair of pressings of the female member pressing plate 77. The strip 772 presses the left and right positions outside the fitting hole 62 in the female side bracket 61.

  Then, by continuing these pressing and clamping states, as shown in FIG. 4B, the pair of return portions 522 interfere with the hole wall of the fitting hole 62, thereby causing the pair of one-side split projections 521 to approach each other. The locking cylinder 52 is press-fitted into the fitting hole 622 while elastically deforming in the direction.

  Then, by pressing the male and female members 60, 50 to the end by the male and female pressing plates 77, 76, the one-sided protrusion 521 of the locking cylinder 52 is inserted into the fitting hole 62 as shown in FIG. The pair of return portions 522 that have penetrated and are elastically deformed thereby are restored to the original in the escape groove 771 of the female member pressing plate 77. By this restoration, the return portion 522 is locked to the hole edge of the fitting hole 62, whereby the male side bracket 51 and the female side bracket 61 are prevented from being detached from each other.

  At this time, the tip side (the upper side in FIG. 4) of the pair of one-side split protrusions 521 once presses the retaining piece 63 of the female bracket 61 upward, as shown in FIG. 4, the retaining pieces 63 are elastically deformed upward in FIG. 4. However, when the pair of return portions 522 are pulled upward from the fitting holes 62, the respective return portions 522 are restored to their original shapes, thereby a pair of one-side cracks. A gap is generated between the protrusions 521.

  Therefore, as shown in FIG. 4C, since the retaining piece 63 is fitted between the pair of one-sided protrusions 521, the paired one-sided protrusions 521 are prevented from being elastically deformed toward each other. Therefore, even when an external force is applied to the wrapping tool 10 in a state where the wrapping tool 10 is attached to the electric wire L, it is possible to reliably cause a problem that the male and female members 60 and 50 of the joining means 40 are separated. Can be prevented.

  FIG. 5 is a perspective view showing a joining processing tool 70 ′ according to the second embodiment. The joining processing tool 70 ′ of the second embodiment employs a pressing plate 75 ′ made of bamboo instead of the previous pressing plate 75 made of wood in the tool main body 71.

  The reason why the pressing plate 75 'made of bamboo is used is as follows. That is, the cut piece obtained by cutting the bamboo material vertically and horizontally is formed in an arc shape when viewed from the direction orthogonal to the direction in which the bamboo fiber extends, and the arc surface on the surface side of the cut piece is used. Can provide the same function as the push-in protrusion 761 of the male member pressing plate 76 of the first embodiment, and the relief of the female member pressing plate 77 of the first embodiment can be achieved by utilizing the arc surface on the back surface side. This is because a function similar to that of the groove 771 can be expected.

  In the joining processing tool 70 ′ of the second embodiment, the bamboo male member pressing plate 76 ′ cuts the bamboo material along the bamboo fiber so that the central angle of curvature is 45 ° to 90 °. In addition, it is formed by cutting to a predetermined length dimension perpendicular to the fiber direction.

  Further, the female member pressing plate 77 ′ made of bamboo is set to have a slightly larger central angle of curvature than that of the male member pressing plate 76 ′, and the length dimension is the same as that of the male member pressing plate 76 ′. Even setting.

  In particular, in the female member pressing plate 77 ′, an escape groove 771 similar to that of the first embodiment is provided for the sake of safety so that the return portion 522 passing through the fitting hole 62 can be surely escaped. Yes.

  Among such pressing plates 76 ′ and 77 ′, the male member pressing plate 76 ′ has the back side of the cut piece of bamboo material attached to the upper surface side of one (the lower side in the example shown in FIG. 5) operation portion 73. And thereby convex upward.

  The female member pressing plate 77 ′ is formed by attaching the surface side of the bamboo cut piece to the lower surface side of the other operation portion 73 (upper side in the example shown in FIG. 5), and thereby convex upward (that is, lower) Is concave). The female member pressing plate 77 ′ has an upwardly convex arc shape in FIG. 5 in an end view, and a pressing strip 772 ′ is formed by each edge portion on both sides thereof. The female bracket 61 of the female member 60 is pressed by the pair of pressing strips 772 '. Other configurations of the joining processing tool 70 ′ of the second embodiment are the same as those of the joining processing tool 70 of the first embodiment.

    According to the joining processing tool 70 ′ of the second embodiment, the male male member pressing plate 76 and the female member pressing plate 77 of the first embodiment are respectively made of the bamboo male member pressing plate 76 ′ and the female member pressing plate. Only the plate 77 'is changed, and the same effect as the joining processing tool 70 of the first embodiment can be obtained.

  By employing the joining processing tools 70, 70 ′ of the first and second embodiments as described above, the joining operation of the male member 50 and the female member 60 performed when the winding tool 10 is attached to the electric wire L, Compared with the case where a conventional fingertip or a conventional tool such as pliers is used, the operation can be performed in a much shorter time. As a result, the work of attaching the winding tool 10 to the electric wire L can be performed. Can greatly improve the performance.

  As described above in detail, the joining processing tools 70, 70 ′ according to the first and second embodiments are extended from a pair of rod-shaped gripping rods 72 for gripping and the tips of the gripping rods 72. A pair of operation portions 73 is provided, and a boundary position between the gripper rod 72 and the operation portion 73 is connected to be rotatable around the connection shaft 74, and a predetermined object to be processed (in the present embodiment, the wrapping tool 10). ) And the female member 60 in which the fitting hole 62 into which the locking columnar body 52 is inserted in the locked state is formed. , 73 can be pressed and clamped respectively.

  The one operation unit 73 is provided with male member pressing plates 76 and 76 ′ on the surface facing the other operation unit 73, and the other operation unit 73 is connected to the one operation unit 73. Female member pressing plates 77 and 77 'are provided on the opposing surfaces.

  Further, the male member pressing plates 76, 76 'are provided with one pushing projection 761 projecting to press the male member 50 (in the second embodiment, the top of the arc-shaped male member pressing plate 76' itself is the first portion). The push-in protrusion 761 of the embodiment is substituted).

  The female member pressing plates 77 and 77 ′ are provided with two pressing strips 772 and 772 ′ provided so as to press the female member 60, and the male and female members 60 and 50 are connected to one pressing projection 761. The two pressing strips 772, 772 'are joined to each other by a three-point pressing process.

  According to such a configuration, when the male and female members 60 and 50 are prevented from being separated from each other by using the joining processing tool, first, the pair of operation parts are set in a state where the opposing surfaces of the male and female members 60 and 50 are brought close to each other. The male and female members 60 and 50 are sandwiched between the 73 male member pressing plates 76 and 76 'and the female member pressing plates 77 and 77'.

  At this time, the male member pressing plates 76 and 76 ′ are applied to the male member 50, and the female member pressing plates 77 and 77 ′ are applied to the female member 60. By firmly squeezing the pair of gripping rods 72 gripped in this state, the male member pressing plates 76 and 76 ′ and the female member pressing plates 77 and 77 ′ are rotated in the direction of approaching each other around the connecting shaft 74. The male and female members 60 and 50 are thereby brought into contact with each other and pressed and held therebetween.

  The male and female members 60, 50 have one pushing protrusion 761 with which the portion corresponding to the locking cylinder 52 of the male member 50 abuts and the portion corresponding to the fitting hole 62 of the female member 60. Three points are pressed by the two pressing strips 772 and 772 'that are in contact with each other, so that the locking cylinder 52 and each point are reliably brought into contact with the male and female members 60 and 50 without waste. Thus, the pressing process can be performed in a stable state.

  In particular, since the pushing protrusion 761 is in contact with the portion of the male member 50 corresponding to the locking cylinder 52, the pressing force generated by operating the grip rod 72 is reliably transmitted to the locking cylinder 52. be able to.

  Further, since the state of the fitting hole 62 is stabilized by bringing the two pressing strips 772 and 772 ′ into contact with the female member 60 across the fitting hole 62, the gripper 72 is operated. The locking cylinder 52 can be easily fitted into the fitting hole 62.

  In this embodiment, the two pressing strips 772 and 772 ′ are based on the fitting hole 62 of the female member 60 in a state where the pushing protrusion 761 is made to correspond to the locking cylinder 52 of the male member 50. The installation positions of the pushing protrusions 761 and the pressing strips 772 and 772 ′ are set so as to substantially face the left and right target positions. Further, the locking cylindrical body 52 of the male member 50 is fitted into the fitting hole 62 of the female member 60 by pressing and clamping between the pressing protrusion 761 and the pressing strips 772 and 772 ′.

  According to such a configuration, even if the male and female members 60 and 50 are flexible with rubber or soft synthetic resin, the two pressing strips 772 and 772 ′ have the fitting holes 62. Since the shape retaining property of the fitting hole 62 is ensured by straddling, the locking cylinder 52 can be securely fitted into the fitting hole 62.

  Further, in the present embodiment, the male member 50 is formed in a bifurcated shape by a pair of one-side split protrusions 521 each having a return portion 522 that faces each other and protrudes in the opposite direction at the tip. .

  The fitting hole 62 is dimensioned so that each return part 522 is locked to the hole edge so that the return part 522 can be prevented from coming off when the pair of one-side split protrusions 521 are inserted through, and the female member 60 is connected to each return part 522. Is provided with a retaining piece 63 that can be pushed between the pair of one-sided protrusions 521 while being engaged with the hole edge of the fitting hole 62.

  According to such a configuration, when the pair of one-side split projections 521 that are the locking cylinders 52 of the male member 50 are being passed through the fitting holes 62 of the female member 60, the pair of barbs at the tip of each one-side split projection 521 is returned. The part 522 interferes with the inner peripheral surface of the fitting hole 62, whereby the one-side crack projections 521 are elastically deformed toward the directions approaching each other.

  When the pair of return portions 522 protrudes from the fitting hole 62 to the outside, the pair of elastically deformed one-side split projections 521 is restored to the original state, and thereby the pair of return portions 522 are holes of the fitting hole 62. Since it is locked to the edge, the one-sided protrusion 521 is prevented from coming off from the fitting hole 62.

  At this time, the retaining piece 63 provided on the female member 60 is pushed between the pair of return portions 522, so that the pair of return portions 522 are elastically deformed in the direction in which the pair of return portions 522 approach each other. It is possible to reliably prevent the occurrence of an inconvenience that would cause the user to escape.

  In the joining processing tool 70 according to the first embodiment, the pushing protrusion 761 protrudes from the male member pressing plate 76 so as to correspond to the locking cylinder 52, and thus the male member 50 is pushed by the pushing protrusion 761. The portion corresponding to the locking cylinder 52 of the male member pressing plate 76 can be intensively pressed.

  Further, according to the detachment prevention processing tool 70 ′ of the second embodiment, the push-in protrusion 761 is an arc-shaped portion in which the opposing surface of the male member pressing plate 76 ′ to the female member pressing plate 77 ′ is bulged in an arc shape. Since it is formed by the top, the male bracket 51 and the female bracket 61 are deformed in an arc shape, and the distance between the distal ends of the pair of one-side split projections 521 is widened. It is easy to get in between.

  Then, by connecting the male and female members 60, 50 to each other by using the joining processing tools 70, 70 'in this way, pliers that are held by hand as in the prior art or that are simply clamped instead of being supported by three points. Compared to the case of using a wrench or the like, the male and female members 60, 50 of the flat plate-like member 20 can be easily combined, which can contribute to the reduction of fatigue during work and the improvement of work efficiency.
