ところが、上記従来技術で前記コア体が前記胴体部と別体で形成された管継手は、管材を接続するために、前記コア体を前記管材の先端部に挿着する挿着作業の後、前記コア体が挿着された前記管材の先端部を前記胴体部に挿入する挿入作業を行う必要がある。
一方、前記コア体が前記胴体部と一体で形成された管継手は、管材を接続するために、前記管材の先端部を前記胴体部に挿入する挿入作業の後、袋ナットを締め付ける等して前記管材を前記胴体部に固定する固定作業を行う必要がある。
即ち、上記従来の管継手は、前記管材の接続に２つの作業を要するものであるから、該接続が煩雑であるという問題があった。
本考案は、このような従来技術に存在する問題点に着目してなされたものである。その目的とするところは、管材の接続に係る作業が簡易な管継手を提供することにある。 However, the pipe joint in which the core body is formed separately from the body portion in the above-described prior art, after the insertion work of inserting the core body into the distal end portion of the pipe material in order to connect the pipe material, It is necessary to perform an insertion operation of inserting the distal end portion of the tube material, to which the core body is inserted, into the body portion.
On the other hand, a pipe joint in which the core body is formed integrally with the body portion is formed by, for example, tightening a cap nut after an insertion operation of inserting the distal end portion of the tube material into the body portion in order to connect the pipe material. It is necessary to perform a fixing operation for fixing the tube material to the body portion.
That is, since the conventional pipe joint requires two operations for connecting the pipe members, there is a problem that the connection is complicated.
The present invention has been made paying attention to such problems existing in the prior art. The purpose of the invention is to provide a pipe joint that can be easily used for connecting pipe materials.

上記の目的を達成するために、請求項１に記載の管継手の考案は、管材の端部が挿入される通孔が内部に設けられた胴体部と、前記胴体部と別体で形成されて前記管材の端部に内挿されるコア体とを有しているとともに、前記コア体の基端部に接合部が設けられ、前記胴体部の前記通孔の内奥に被接合部が設けられており、前記接合部が前記被接合部に対して螺着、係着、接着又は溶着されていることを要旨とする。
請求項２に記載の考案は、請求項１に記載の管継手の考案において、前記接合部には雄ネジが螺刻され、前記被接合部には雌ネジが螺刻されており、前記接合部が前記被接合部に対して螺着されていることを要旨とする。

As shown in FIG. 1, a pipe joint 10 according to an embodiment is for connecting pipe materials 11 such as polyethylene pipes, polyvinyl chloride pipes, cross-linked polyethylene pipes, and polybutene pipes used for water pipes. A portion 12, a cap body 13, and a core body 14 are included.

図２に示すように、前記胴体部１２は、両端が開口された直線形の略長筒状に形成されており、該胴体部１２の内部には、前記管材１１の端部が挿入される通孔２１が設けられている。
前記胴体部１２の両端の開口のうち先端のものは、前記管材１１を前記通孔２１へ挿入する挿入口２２とされている。前記胴体部１２の両端のうち基端部の外周面には、該胴体部１２を他の機器（図示せず）等に取着可能にするための取着用雄ネジ２３が形成されている。
前記胴体部１２の前記挿入口２２直近の内周面には、前記キャップ体１３を装着するための装着用雌ネジ２４が形成されている。前記通孔２１の略中央の内周面には周溝２５が凹設されており、該周溝２５にＯリング２６が装着されるように構成されている。
そして、前記胴体部１２の前記通孔２１において、前記周溝２５よりも更に内奥には、雌ネジが螺刻されることによって被接合部２７が設けられている。 As shown in FIG. 2, the body portion 12 is formed in a substantially long cylindrical shape with both ends opened, and the end portion of the tube material 11 is inserted into the body portion 12. A through hole 21 is provided.
Of the openings at both ends of the body portion 12, the one at the tip is an insertion port 22 for inserting the tube material 11 into the through hole 21. On the outer peripheral surface of the base end portion of both ends of the body portion 12, a mounting male screw 23 is formed for enabling the body portion 12 to be attached to another device (not shown).
A mounting female screw 24 for mounting the cap body 13 is formed on the inner peripheral surface of the body portion 12 in the immediate vicinity of the insertion port 22. A circumferential groove 25 is formed in a substantially central inner circumferential surface of the through-hole 21, and an O-ring 26 is attached to the circumferential groove 25.
In the through hole 21 of the body portion 12, a joined portion 27 is provided by screwing a female screw further inside the circumferential groove 25.

図１に示すように、前記キャップ体１３は、両端が開口された略短筒状に形成されている。前記キャップ体１３の基端部の外周面には、前記胴体部１２に装着するべく前記装着用雌ネジ２４と螺合可能な装着用雄ネジ３１が形成されている。
前記キャップ体１３の内側には、基端から略中央の範囲で内周面を基端へ向かうにつれて広がるテーパー状とすることにより、テーパー穴３２が設けられている。
前記キャップ体１３の前記テーパー穴３２内には、前記胴体部１２内からの前記管材１１の端部の抜け出しを規制する抜け止め手段として、弾性リング３３が装着されている。該弾性リング３３は、外周面が前記テーパー穴３２に応じた形状のテーパー状とされているとともに、内周面に複数の環形突条３３Ａが列設されている。前記弾性リング３３は、前記胴体部１２に対して前記キャップ体１３を締め付ける際、該キャップ体１３の前記テーパー穴３２の内周面が前記弾性リング３３の外周面に摺接されることで径が縮み、環形突条３３Ａを前記管材１１の周壁に食い込ませることで、前記管材１１の端部の抜け出しを規制するように構成されている。
また、前記弾性リング３３は、前記キャップ体１３の基端部にリング形の座板３４が装着されることによって、該キャップ体１３からの脱落を防止されている。 As shown in FIG. 1, the cap body 13 is formed in a substantially short cylindrical shape having both ends opened. On the outer peripheral surface of the base end portion of the cap body 13, a mounting male screw 31 that can be screwed with the mounting female screw 24 to be mounted on the body portion 12 is formed.
A tapered hole 32 is provided on the inner side of the cap body 13 by forming a tapered shape in which the inner peripheral surface extends from the base end toward the base end in a substantially central range.
An elastic ring 33 is mounted in the tapered hole 32 of the cap body 13 as a retaining means for restricting the end of the tube 11 from slipping out of the body 12. The elastic ring 33 has a tapered outer peripheral surface corresponding to the tapered hole 32, and a plurality of annular protrusions 33A are arranged on the inner peripheral surface. When the cap body 13 is tightened with respect to the body portion 12, the elastic ring 33 has a diameter such that the inner peripheral surface of the tapered hole 32 of the cap body 13 is in sliding contact with the outer peripheral surface of the elastic ring 33. And the ring-shaped protrusion 33 </ b> A bites into the peripheral wall of the tube material 11, thereby restricting the end of the tube material 11 from being pulled out.
The elastic ring 33 is prevented from falling off the cap body 13 by mounting a ring-shaped seat plate 34 on the base end portion of the cap body 13.

図３に示すように、前記コア体１４は、両端が開口された略短筒状に形成されている。前記コア体１４は、外周面が先端へ向かうにつれて縮むテーパー状とされることにより、前記管材１１内へ挿入しやすくなるように構成されている。前記コア体１４の基端部には、外周面に鍔部４１が突設されている。前記鍔部４１は、前記コア体１４の前記管材１１内への挿入の際、該管材１１の端面に当接することにより、これ以上の前記コア体１４の前記管材１１内への挿入を規制する。
前記コア体１４において、該コア体１４の基端から前記鍔部４１までの範囲にわたる基端部は、接合部４２とされており、該接合部４２の外周面には雄ネジが螺刻されている。 As shown in FIG. 3, the core body 14 is formed in a substantially short cylindrical shape having both ends opened. The core body 14 is configured to be easily inserted into the tube material 11 by being tapered such that the outer peripheral surface is contracted toward the tip. At the base end portion of the core body 14, a flange portion 41 projects from the outer peripheral surface. When the core body 14 is inserted into the tube material 11, the flange 41 abuts against the end surface of the tube material 11, thereby restricting further insertion of the core body 14 into the tube material 11. .
In the core body 14, a base end portion ranging from the base end of the core body 14 to the flange portion 41 is a joint portion 42, and a male screw is threaded on the outer peripheral surface of the joint portion 42. ing.
