従来より配管工事などでパイプにエルボやカップリングなどの管接手を接続す るときや既設の配管系を解体するときパイプレンチが多用されているが、その際 、パイプレンチのナット輪を回してレンチの挾持受歯と挾持係合歯間の挾持間隔 を所望の間隔に調節しているが、この作業はパイプ径や管接手の種類によりその 都度挾持間隔を調整しなければならないので手間のかかる厄介な作業であった。 本考案は上記の欠点を解決し迅速容易に挾持受歯と挾持係合歯間の挾持間隔を 所望の挾持間隔に調整できるパイプレンチを提供するものである。 Conventionally, pipe wrenches are often used when connecting pipe joints such as elbows and couplings to pipes during pipe work, or when disassembling existing pipe systems.At that time, turn the nut ring of the pipe wrench. The holding distance between the holding tooth and the holding engaging tooth of the wrench is adjusted to the desired distance, but this work is troublesome because the holding distance must be adjusted each time depending on the pipe diameter and the type of pipe joint. It was a difficult task. SUMMARY OF THE INVENTION The present invention provides a pipe wrench that solves the above-mentioned drawbacks and can quickly and easily adjust the holding interval between the holding teeth and the holding engagement teeth to a desired holding distance.

When tightened, the female thread notch 10 of the nut ring 9 fits into the upper and lower male threads 8 of the wrench rod 4, so that the grip portion 13 connected to the rear end of the wrench rod 4 is gripped and the wrench rod 4 is slid backward. The gripping engagement teeth 7 are brought into contact with the outer diameter of the pipe wrench a on the opposite side of the gripping receiving teeth 3, and the nut wheel 9 is rotated in the tightening direction by the switching handle rod 12 to move the gripping receiving teeth 3 and the gripping teeth 3. Hold the pipe a with the holding engagement teeth 7 and tap the wrench rod 4 above the holding engagement teeth 7 to bite the tips of the holding engagement teeth 7 and the holding teeth 3 into the outer diameter of the pipe a. No, turn the other end of the grip handle 1 and screw in the pipe a.
【０００６】 螺子込み作業が終わったら、切り換えハンドル杆12を弛み方向に回動させて切 り換えハンドル杆12をストッパー片11の後端部11'に当接させると、ナット輪９ の螺子作用によりレンチ杆４が前進して挾持受歯３と挾持係合歯７によるパイプ ａの挾持が解除されると共に雌螺子部９'とレンチ杆４の雄螺子８との螺合が解 消されるので、握り部13によりレンチ杆４をスライドさせて挾持受歯３と挾持係 合歯７との挾持間隔を開きパイプａよりパイプレンチを外す。After the screwing operation is completed, the switching handle rod 12 is rotated in the slack direction to bring the switching handle rod 12 into contact with the rear end portion 11 ′ of the stopper piece 11, so that the screw action of the nut ring 9 is performed. As a result, the wrench rod 4 moves forward and the holding of the pipe a by the holding teeth 3 and the holding engagement teeth 7 is released, and the screw engagement between the female screw portion 9'and the male screw 8 of the wrench rod 4 is released. The gripping portion 13 slides the wrench rod 4 to open the holding interval between the holding tooth 3 and the holding engaging tooth 7, and remove the pipe wrench from the pipe a.

本考案は上記のように構成したので、切り換えハンドル杆を弛み方向に回動さ せて切り換えハンドル杆をストッパー片に当接させると、ナット輪の雌螺子除去 部がレンチ杆の雄螺子部に位置するので握り部によりレンチ杆をスライドさせて 挾持係合歯と挾持受歯の間の挾持間隔を迅速に所望の間隔に調節でき、また切り 換えハンドルの回動によりワンタッチで挾持歯のパイプへの締め込み・締め戻し が可能となるので、従来のようにナット輪をぐるぐる回動して挾持間隔を調節固 定する手間が著しく短縮され、且つスライドにより指を挾むことの危険の少ない 実用的で作業効率の良い秀れたパイプレンチとなる。 Since the present invention is configured as described above, when the switching handle rod is rotated in the slacking direction to bring the switching handle rod into contact with the stopper piece, the female thread removal portion of the nut ring becomes the male thread portion of the wrench rod. Since it is located, you can quickly adjust the holding interval between the holding engagement teeth and the holding teeth by sliding the wrench rod with the grip, and by turning the switching handle to the holding teeth pipe with one touch. Since it is possible to tighten and unfasten the nut, it is possible to significantly reduce the time and effort to adjust the gripping interval by rotating around the nut ring as in the past, and to reduce the risk of pinching the fingers by sliding. It is an excellent pipe wrench with good working efficiency.
