Description

本発明は、雌型連結部材に関する。 The present invention relates to a female connecting member.

従来、部材相互を連結する連結具として、図７，図８に示すように、雌型連結部材１０１と雄型連結部材２０１で構成され、雌型連結部材１０１を回転することなく、雄型連結部材２０１と締結できるものが知られている。 Conventionally, as a connecting tool for connecting members to each other, as shown in FIGS. 7 and 8, a female connecting member 101 and a male connecting member 201 are configured, and the female connecting member 101 is connected to the male without rotating. Those that can be fastened to the member 201 are known.

この雌型連結部材１０１は、内部に、その軸方向の両端が開口するテーパ穴１０２を形成するとともに、そのテーパ穴１０２の内面に軸方向に沿った摺動案内突条を周方向に分割して複数形成したケーシング１０３と、外面をテーパ穴１０２に沿うテーパ面に形成するとともに内面に雌ねじ１０４を形成した雌型係止部材（楔ナット）１０５と、この楔ナット１０５を押圧する圧縮バネ１０６と、止め部材１０７を有する。 The female connecting member 101 internally forms a tapered hole 102 in which both ends in the axial direction open, and a sliding guide ridge along the axial direction is divided in the circumferential direction on the inner surface of the tapered hole 102. A plurality of casings 103 formed therein, a female locking member (wedge nut) 105 having an outer surface formed on a tapered surface along the tapered hole 102 and a female screw 104 formed on the inner surface, and a compression spring 106 for pressing the wedge nut 105. And has a stop member 107.

そして、この連結具における連結に際しては、雌型連結部材１０１に雄型連結部材２０１を、相互に回転することなく挿通することにより、分割された楔ナット１０５の雌ねじ１０４が雄型連結部材２０１の雄ねじ１１０に係合してその楔ナット１０５が圧縮バネ１０６に抗して大径側へ押され、楔ナット１０５で形成される雌ねじ穴の内径が拡径して雄型連結部材２０１を雌型連結部材１０１の所定位置まで挿通でき、その挿通が終ると、圧縮バネ１０６の付勢力によって楔ナット１０５の雌ねじ１０４が雄型連結部材２０１の雄ねじ２０２に噛合し、雌型連結部材１０１と雄型連結部材２０１の連結が行われるようになっている（例えば、特許文献１参照）。 Then, at the time of connection in this connecting tool, the male connecting member 201 is inserted into the female connecting member 101 without rotating with each other, so that the female screw 104 of the divided wedge nut 105 is inserted into the male connecting member 201. Engaging with the male screw 110, the wedge nut 105 is pushed toward the large diameter side against the compression spring 106, and the inner diameter of the female screw hole formed by the wedge nut 105 is expanded to form the male connecting member 201. The connecting member 101 can be inserted to a predetermined position, and when the insertion is completed, the female screw 104 of the wedge nut 105 meshes with the male screw 202 of the male connecting member 201 by the urging force of the compression spring 106, and the female connecting member 101 and the male type are inserted. The connecting member 201 is connected (see, for example, Patent Document 1).

発明を実施するための形態を図に示す実施例に基づいて説明する。 A mode for carrying out the invention will be described with reference to the examples shown in the figure.

［実施例１］
図１乃至図３は、本発明の実施例１を示す。 [Example 1]
1 to 3 show Example 1 of the present invention.

図１は、本実施例１の雌型連結部材１の半面を断面とした部分断面図を示し、図２は、その正面図を示すものである。 FIG. 1 shows a partial cross-sectional view of the female connecting member 1 of the first embodiment as a cross section, and FIG. 2 shows a front view thereof.

雌型連結部材１は、ケーシング３を有し、このケーシング３の縦断面の外形は、図２に示すように、ナット状の六角形に形成され、その内部には、軸芯Ｘ−Ｘ方向の両端が開口する収納室４が形成されている。なお、ケーシング３の外径は六角形状以外にも、円筒状や多角形状など任意の形状に形成することができる。 The female connecting member 1 has a casing 3, and the outer shape of the vertical cross section of the casing 3 is formed in a nut-shaped hexagon as shown in FIG. A storage chamber 4 is formed in which both ends of the container are open. The outer diameter of the casing 3 can be formed into any shape such as a cylindrical shape or a polygonal shape in addition to the hexagonal shape.

収納室４の先部の内周面は、雌型連結部材１と連結する雄型連結部材２の挿入側（一方側）４ａ側から奥部側（他方側）４ｂにかけて内径が徐々に拡大するテーパ面にしてなる円錐状のテーパ穴５に形成され、収納室４の後部は円筒状に形成されている。ケーシング３の後端部には、中央部に挿通穴８ａが形成された止め部材８がカシメ等により固設されている。止め部材８は、板状部材で鍔状に形成されている。 The inner peripheral surface of the front portion of the storage chamber 4 gradually expands in inner diameter from the insertion side (one side) 4a side to the back side (other side) 4b of the male connecting member 2 connected to the female connecting member 1. It is formed in a conical tapered hole 5 having a tapered surface, and the rear portion of the storage chamber 4 is formed in a cylindrical shape. At the rear end of the casing 3, a stopper 8 having an insertion hole 8a formed in the center thereof is fixedly fixed by caulking or the like. The stop member 8 is a plate-shaped member and is formed in a brim shape.

収納室４の挿入側部には円筒状の挿入部９が形成され、挿入部９の挿入側４ａは開口している。 A cylindrical insertion portion 9 is formed on the insertion side portion of the storage chamber 4, and the insertion side 4a of the insertion portion 9 is open.

テーパ穴５内には、ケーシング３の軸芯Ｘ−Ｘ方向に沿った摺動案内突条（図示せず）が、周方向に複数形成されている。また、テーパ穴５内には、周方向に複数に分割してなる楔状の雌型係止部材１２が、摺動案内突条の相互間においてケーシング３の軸芯Ｘ−Ｘ方向に摺動可能に配設されている。雌型係止部材１２の数を、本実施例においては、図２に示すように３個としたが、その数は、１個でも複数でも良く任意に設定することができる。また、雌型係止部材１２を円筒状に形成し、挿入側４ａ端から奥部４ｂ側への切れ込みと、奥部４ｂ側端から挿入側４ａ側への切れ込みを、周方向に向かって交互に複数形成することにより、一体に形成された雌型係止部材１２の後述する雌ねじ穴１２ｃが、拡径したり、縮径したりできるようにしてもよい。なお、以下において、雌型係止部材１２を楔ナット１２ともいう。 A plurality of sliding guide ridges (not shown) along the axis XX direction of the casing 3 are formed in the tapered hole 5 in the circumferential direction. Further, in the tapered hole 5, a wedge-shaped female locking member 12 divided into a plurality of parts in the circumferential direction can slide between the sliding guide ridges in the axial core XX direction of the casing 3. It is arranged in. In this embodiment, the number of female locking members 12 is set to 3 as shown in FIG. 2, but the number may be one or a plurality, and can be arbitrarily set. Further, the female locking member 12 is formed in a cylindrical shape, and the notch from the insertion side 4a end to the back portion 4b side and the notch from the back portion 4b side end to the insertion side 4a side are alternately alternated in the circumferential direction. The female screw holes 12c, which will be described later, of the female locking member 12 integrally formed may be enlarged or reduced in diameter by forming a plurality of the female screw holes 12c. In the following, the female locking member 12 is also referred to as a wedge nut 12.

更に、楔状の雌型係止部材１２の外面は、前記テーパ穴５のテーパ面に沿った、すなわち、挿入側４ａ側から奥部４ｂにかけて外径が徐々に拡大するテーパ面１２ａに形成されている。更に、各雌型係止部材１２の内周面には、螺旋状の係止山及び係止溝からなる係止部（雌ねじ）１２ｂが、ケーシング３の軸芯Ｘ−Ｘを中心とする円弧でかつ軸芯Ｘ−Ｘに沿った方向に刻設されている。この螺旋状の係止部１２ｂは、螺旋状に形成されていれば、その断面形状としては任意の形状のねじ山を用いることができ、その軸方向断面が、二等辺三角形状、直角三角形状、不等辺三角形状等の任意の形状に形成することができる。また、係止山間の間隔（ピッチ）の寸法は、任意に設定することができる。 Further, the outer surface of the wedge-shaped female locking member 12 is formed along the tapered surface of the tapered hole 5, that is, on the tapered surface 12a whose outer diameter gradually increases from the insertion side 4a side to the inner portion 4b. There is. Further, on the inner peripheral surface of each female locking member 12, a locking portion (female screw) 12b composed of a spiral locking mountain and a locking groove is formed by an arc centered on the axis XX of the casing 3. And it is engraved in the direction along the axis XX. As long as the spiral locking portion 12b is formed in a spiral shape, a screw thread having an arbitrary shape can be used as its cross-sectional shape, and its axial cross section has an isosceles right triangle shape or a right-angled triangular shape. , It can be formed into any shape such as an isosceles right triangle. Further, the dimension of the spacing (pitch) between the locking ridges can be arbitrarily set.

上記により、複数個の楔ナット１２により、図１〜３に示すように、係止穴（雌ねじ穴）１２ｃが形成され、各楔ナット１２がテーパ穴５に沿って奥部４ｂ側へ後退することにより、その雌ねじ穴１２ｃが拡径され、挿入４ａ側へ移動することにより、その雌ねじ穴１２ｃが縮径するようになっている。 As described above, as shown in FIGS. 1 to 3, the plurality of wedge nuts 12 form a locking hole (female screw hole) 12c, and each wedge nut 12 retracts toward the inner portion 4b along the tapered hole 5. As a result, the female screw hole 12c is expanded in diameter, and by moving to the insertion 4a side, the female screw hole 12c is reduced in diameter.

なお、摺動案内突条は、任意に形成することができ、例えば、螺旋状に形成し、雌型係止部材１２が奥部４ｂに移動するほど、雌型係止部材１２の雌ねじ１２ｂと雄側連結部材２に形成した後述する雄ねじ２ａとの締結が緩むようにしてもよい。また、摺動案内突条を設けなくてもよいが、摺動案内突条を設けた場合には、雌型連結部材１と雄型連結部材２の連結状態において、雄型連結部材２を雌型連結部材１に対して回動させやすく、連結状態を解除し易くなる。 The sliding guide ridge can be formed arbitrarily. For example, the sliding guide ridge is formed in a spiral shape, and the more the female locking member 12 moves to the inner portion 4b, the more the female screw 12b of the female locking member 12 is formed. The fastening with the male screw 2a, which will be described later, formed on the male side connecting member 2 may be loosened. Further, although it is not necessary to provide the sliding guide ridge, when the sliding guide ridge is provided, the male connecting member 2 is female in the connected state between the female connecting member 1 and the male connecting member 2. It is easy to rotate with respect to the mold connecting member 1, and it is easy to release the connected state.

楔ナット１２の奥側の収納室４内には、移動部材１４が軸芯Ｘ−Ｘ方向に移動可能に設けられている。移動部材１４は、各楔ナット１２に共通して係合するとともに、中央部に貫通穴１４ａが形成された鍔部１４ｂと、鍔部１４ｂの内周端から奥部側に固設された円筒状の案内部１４ｃで構成されている。案内部１４ｃの奥側端は、図１に示すように、雌型連結部材１と雄型連結部材２が非連結状態において、止め部材８よりも挿入側４ａに位置するように形成されている。 A moving member 14 is provided in the storage chamber 4 on the back side of the wedge nut 12 so as to be movable in the axis XX direction. The moving member 14 is commonly engaged with each wedge nut 12, and has a flange portion 14b having a through hole 14a formed in the central portion thereof and a cylinder fixedly installed from the inner peripheral end to the inner peripheral side of the flange portion 14b. It is composed of a shape guide portion 14c. As shown in FIG. 1, the back end of the guide portion 14c is formed so that the female connecting member 1 and the male connecting member 2 are located closer to the insertion side 4a than the stop member 8 in the non-connected state. ..

貫通穴１４ａと案内部１４ｃの内径は、雄型連結部材２の外径よりも大きく設定されている。また、案内部１４ｃの外径は、止め部材８の挿通穴８ａの内径よりも小さく設定されている。 The inner diameters of the through hole 14a and the guide portion 14c are set to be larger than the outer diameter of the male connecting member 2. Further, the outer diameter of the guide portion 14c is set to be smaller than the inner diameter of the insertion hole 8a of the stop member 8.

なお、案内部１４ｃは、本実施例においては、軸芯Ｘ−Ｘ方向全体において略同じ内径で形成された円筒状に構成したが、挿入側４ａほど縮径するように形成してもよいし、挿入側４ａに至る程拡径するように形成してもよい。なお、このように案内部１４ｃを形成した場合、その最外径は、止め部材８の挿通穴８ａの内径よりも小さく設定されている。 In this embodiment, the guide portion 14c is formed in a cylindrical shape having substantially the same inner diameter in the entire axis XX direction, but may be formed so as to reduce the diameter by about 4a on the insertion side. , It may be formed so as to expand the diameter as far as the insertion side 4a. When the guide portion 14c is formed in this way, its outermost diameter is set to be smaller than the inner diameter of the insertion hole 8a of the stop member 8.

収納室４内における鍔部１４ｂと止め部材８の間には付勢部材１５が介在されている。付勢部材１５は、コイルバネ、ゴム、樹脂、ウレタンなどの弾性部材で形成される。本実施例１ではコイルバネを使用して圧縮状態で収納されている。この付勢部材１５の付勢力により各楔ナット１２と移動部材１４は、挿入側４ａ方向へ常時付勢されている。 An urging member 15 is interposed between the flange portion 14b and the stopping member 8 in the storage chamber 4. The urging member 15 is formed of an elastic member such as a coil spring, rubber, resin, or urethane. In the first embodiment, a coil spring is used and the mixture is stored in a compressed state. The wedge nut 12 and the moving member 14 are constantly urged in the insertion side 4a direction by the urging force of the urging member 15.

雄型連結部材２は、図３に示すように、棒状に形成され、その外周面には、軸芯Ｘ−Ｘを中心とする螺旋状の係止山及び係止溝からなる係止部（雄ねじ）２ａが、ケーシング３の軸芯Ｘ−Ｘに沿った方向に刻設されている。この螺旋状の係止部２ａは、螺旋状に形成され、各雌型係止部材１２の係止部１２ｂと係合できれば、その断面形状としては任意の形状のねじ山を用いることができ、その軸方向断面が、二等辺三角形状、直角三角形状、不等辺三角形状等の任意の形状に形成することができる。 As shown in FIG. 3, the male connecting member 2 is formed in a rod shape, and on the outer peripheral surface thereof, a locking portion (a locking portion composed of a spiral locking crest and a locking groove centered on the axis XX). The male screw) 2a is engraved in the direction along the axis XX of the casing 3. The spiral locking portion 2a is formed in a spiral shape, and if it can be engaged with the locking portion 12b of each female locking member 12, a thread having an arbitrary shape can be used as its cross-sectional shape. The axial cross section can be formed in any shape such as an isosceles triangle, a right-angled triangle, and an unequal triangle.

雌型連結部材１と雄型連結部材２で連結具２０が構成されている。 The connecting tool 20 is composed of the female connecting member 1 and the male connecting member 2.

次に、雌型連結部材１と雄型連結部材２の連結方法について説明する。 Next, a method of connecting the female connecting member 1 and the male connecting member 2 will be described.

雄型連結部材２を、雌型連結部材１の挿入側４ａから収納室４内へ、相互に回転することなく挿入する。この雄型連結部材２の挿入により、各楔ナット１２が奥部４ｂ側へ押され、楔ナット１２と移動部材１４が付勢部材１５の付勢力に抗して後退する。雄型連結部材２は、各楔ナット１２で形成されるねじ穴１２ｃを拡径させ、各楔ナット１２の係止部１２ｂの係止山を乗り越えつつ、収納室４内へ挿入される。 The male connecting member 2 is inserted into the storage chamber 4 from the insertion side 4a of the female connecting member 1 without rotating with each other. By inserting the male connecting member 2, each wedge nut 12 is pushed toward the inner portion 4b, and the wedge nut 12 and the moving member 14 retract against the urging force of the urging member 15. The male connecting member 2 is inserted into the storage chamber 4 while expanding the diameter of the screw hole 12c formed by each wedge nut 12 and overcoming the locking ridge of the locking portion 12b of each wedge nut 12.

そして、雌型連結部材１と雄型連結部材２の連結時において、図３に示すように、雌型連結部材１の軸芯Ｘ−Ｘに対して、雄型連結部材２の軸芯Ｙ−Ｙが所定以上傾いた状態であると、図３に示すように、雄型連結部材２の係止部２ａが、移動部材１４の案内部１４ｃの内周面に当接し、雌型連結部材１の軸芯Ｘ−Ｘ側に案内され、雄型連結部材２の係止部２ａが、止め部材８に係合することが抑制され、雄型連結部材２が所定の位置まで挿入される。この際、案内部１４ｃの奥側端が、止め部材８から外側に突出していてもよい。 Then, when the female connecting member 1 and the male connecting member 2 are connected, as shown in FIG. 3, the shaft core Y-of the male connecting member 2 is relative to the shaft core XX of the female connecting member 1. When Y is tilted by a predetermined value or more, as shown in FIG. 3, the locking portion 2a of the male connecting member 2 comes into contact with the inner peripheral surface of the guide portion 14c of the moving member 14, and the female connecting member 1 Guided to the axis XX side of the above, the locking portion 2a of the male connecting member 2 is suppressed from engaging with the stopping member 8, and the male connecting member 2 is inserted to a predetermined position. At this time, the rear end of the guide portion 14c may protrude outward from the stop member 8.

その後、各楔ナット１２と移動部材１４は、付勢部材１５の付勢力によって挿入部４ａ側へ押し戻され、テーパ穴５によって各楔ナット１２で形成されるねじ穴１２ｃの径が縮径し、各楔ナット１２の係止部１２ｂが雄型連結部材２の係止部２ａに噛合し、雌型連結部材１と雄型連結部材２は連結される。 After that, each wedge nut 12 and the moving member 14 are pushed back to the insertion portion 4a side by the urging force of the urging member 15, and the diameter of the screw hole 12c formed by each wedge nut 12 is reduced by the tapered hole 5. The locking portion 12b of each wedge nut 12 meshes with the locking portion 2a of the male connecting member 2, and the female connecting member 1 and the male connecting member 2 are connected.

上記のように、移動部材１４の案内部１４ｃにより、雄型連結部材２の係止部２ａが、止め部材８の挿通穴８ａに係合することを抑制して、雄型連結部材２を、雌型連結部材１に対して所定の位置まで挿入することができるため、雌型連結部材１と雄型連結部材２を確実に連結し、所定の締結力を確保することができる。 As described above, the guide portion 14c of the moving member 14 suppresses the locking portion 2a of the male connecting member 2 from engaging with the insertion hole 8a of the stopping member 8 to prevent the male connecting member 2 from engaging. Since it can be inserted into the female connecting member 1 to a predetermined position, the female connecting member 1 and the male connecting member 2 can be reliably connected to each other, and a predetermined fastening force can be secured.
