With two elbow type tube joints (1, 1'), tube metal fittings (C, C) of the tube joints (1, 1') on the tube side (B), the sides of the removed tube metal fittings (C, C) are provided oppositely, and portions where the tube metal fittings (C, C) are removed are connected to each other with a swivel metal fitting 3.SELECTED DRAWING: Figure 1

Description

この発明は、自在継手に関するものである。   The present invention relates to a universal joint.

従来、自在継手とは、圧力のある流体や大気圧以下の流体を輸送するに当たり、その配管を回転させたり、上下・左右・前後の任意の方向に移動させる必要がある時に使用するものである。   Conventionally, a universal joint is used when it is necessary to rotate the pipe or move it up / down / left / right / front / rear in order to transport fluid under pressure or fluid below atmospheric pressure. .

また、各種のチューブ継手が市販されている。これらのチューブ継手は、ストレート形、エルボ形、チーズ形のものが市販されており、そのうち、ストレート形は、1ケ所が管用ネジで他方はチューブの外径にワンタッチで接続できる(ワンタッチフィッティング)よう構成されている。   Various tube joints are commercially available. These tube joints are commercially available in straight, elbow, and cheese types. Of these, the straight type can be connected to the tube's outer diameter with one touch at one place (one touch fitting). It is configured.

また、エルボ形(L形ワンタッチ継手)は、1ケ所が管用ネジで他方はチューブの外径にワンタッチで接続できるものと、両側ともワンタッチで接続するものがある。   In addition, there are elbow type (L-shaped one-touch joint) that can be connected to the outer diameter of the tube at one place with one screw and one that can be connected to both sides with one touch.

さらに、チーズ形(T形ワンタッチ継手)は、T字のタテ軸下部1ケ所が管用ネジで他の2方はチューブの外径にワンタッチで接続することができるものと、3方ともワンタッチで接続できるものがある。   In addition, the cheese type (T-type one-touch joint) has a T-shaped vertical shaft lower part at one place, and the other two can be connected to the outer diameter of the tube with one-touch, and all three can be connected with one-touch. There is something you can do.

そしてこれらのチューブ継手(ストレート、エルボ、チーズ)は、ネジ接合によって固定されることを前提に製作されており、ネジ部を持たない両側チューブのエルボや3方チューブのチーズには、固定用の孔が設けられている。   And these tube joints (straight, elbow, cheese) are manufactured on the premise that they are fixed by screw joints. A hole is provided.

ネジ付きのエルボ形やチーズ形は、ネジ部に設けられた6角のスパナ掛かりによって締めこまれるため、ネジ部と継手本体とは適度な抵抗で回転させることができるよう構成されている。尚、スイベル接合されたネジ部はオネジでもメネジでもよい。   Since the threaded elbow or cheese shape is tightened by a hexagonal spanner hook provided on the threaded portion, the threaded portion and the joint body can be rotated with an appropriate resistance. Incidentally, the screw part joined with the swivel may be a male screw or a female screw.

しかしながら、上記のチューブ継手以外の形状をした自在継手は、製造されていない。   However, universal joints having shapes other than the above-described tube joint have not been manufactured.

そこで、この発明の課題は、上記事項に鑑みてなされたものであり、従来のチューブ継手に改良を加えることにより、新たな形状の自在継手を設けることであり、自由に姿勢維持のできるコの字形、あるいはZ字形の自在継手を開発・提供することにある。   Therefore, an object of the present invention has been made in view of the above matters, and is to provide a universal joint of a new shape by adding improvements to the conventional tube joint, so that the posture can be freely maintained. The purpose is to develop and provide character-shaped or Z-shaped universal joints.

この発明の自在継手は、
ネジ部側とチューブ側とを有する,エルボ型チューブ継手を2個用い、
これらチューブ継手のそれぞれチューブ側のチューブ金具を取り外し、
取り外したチューブ金具側が相対するように設け、
これらのチューブ金具を取り外した部分に、それぞれスイベル金具で連結する
ことを特徴とする。
The universal joint of the present invention is
Use two elbow-type tube fittings with thread side and tube side,
Remove the tube fitting on each tube side of these tube fittings,
Install so that the removed tube bracket side is opposite,
Each of these tube fittings is connected to the portion from which the tube fittings have been removed by a swivel fitting.

また、前記の両自在継手のネジ部側には、それぞれオネジとメネジを、またはオネジどうし、あるいはメネジどうしを設けた
ことを特徴とする。
Further, a male screw and a female screw, or a male screw, or a female screw are provided on the screw side of each of the universal joints.

この発明によると、一のエルボ型チューブ継手のチューブ側と他のエルボ型チューブ継手のチューブ側を一体のスイベル金具で連結することにより一体化したコの字形となることにより、あるいは、それを変形させてZの字形とすることにより、片側のネジを配管に連結することによって、反対側のネジ部を自由な方向に向けて固定することができるという効果を奏する。   According to the present invention, the tube side of one elbow-type tube joint and the tube side of another elbow-type tube joint are connected by an integral swivel fitting to form an integrated U-shape, or it can be deformed. By forming the Z shape by connecting the screw on one side to the pipe, there is an effect that the screw portion on the opposite side can be fixed in a free direction.

また、この発明によると、壁面、柱、塀、ラティス等の垂直面、あるいは水平面の上部例えば、梁、屋上、水平面の下面、たとえば軒下、さらには屋根等の傾斜面に、自由に設置することにより、ミスト噴霧用ノズルを直接、あるいは継手を介して取り付けるとミストの噴霧角度を自由に設定することができ、効率的である等の効果を有する。   In addition, according to the present invention, it can be freely installed on a vertical surface such as a wall surface, a pillar, a fence or a lattice, or on an upper surface of a horizontal surface such as a beam, a roof, a lower surface of a horizontal surface such as an eaves, or an inclined surface such as a roof Therefore, if the nozzle for mist spraying is attached directly or via a joint, the spray angle of mist can be freely set, and there are effects such as efficiency.

さらに、この発明のコの字形あるいはZ字形の自在継手を製造するにあたり、主要部品は市販品を用いるため安価で、しかも汎用性も高い等の効果も奏する。   Furthermore, in manufacturing the U-shaped or Z-shaped universal joint of the present invention, the main parts are commercially available, so that they are inexpensive and highly versatile.

以下、この発明について詳細に説明する。尚、この発明においては、以下の記述に限定されるものではなく、この発明の要旨を逸脱しない範囲においては適宜変更可能である。   The present invention will be described in detail below. The present invention is not limited to the following description, and can be appropriately changed without departing from the gist of the present invention.

先ず、この発明の一実施例を図面に基づいて詳述すると、ネジ部側(A)とチューブ側(B)とを有する,エルボ形のチューブ継手(1,1′)を2個用い、これらチューブ継手(1,1′)のそれぞれチューブ(2,2′)側を向かい合わせて設け、これらチューブ側(B)にスイベル金具(3)を接合して一体化し、コ字状、あるいはZ字状にしたことを特徴とする自在継手から構成される。   First, an embodiment of the present invention will be described in detail with reference to the drawings. Two elbow-shaped tube joints (1, 1 ') having a threaded portion side (A) and a tube side (B) are used. The tube joints (1, 1 ') are provided with the tubes (2, 2') facing each other, and the swivel fitting (3) is joined and integrated to these tube sides (B). It is composed of a universal joint characterized by the shape.

そして、前記の両チューブ継手(1,1′)のネジ部側(A)には、オネジ(4)、あるいはメネジ(5)を設けるものであり、使用によって選択するものである。   Then, the male thread (4) or the female thread (5) is provided on the threaded portion side (A) of both the tube joints (1, 1 '), and is selected according to use.

また、チューブ継手(1,1′)は樹脂製であり、一例としてはポリブチレンテレフタレートであり、スイベル金具(3)は、金属製であり、内部を流れる液体の性質によりステンレス製であったり、Oリング(6)の素材の一例としては、フッ素ゴムである。   The tube joint (1, 1 ') is made of resin, for example, polybutylene terephthalate, and the swivel fitting (3) is made of metal and made of stainless steel due to the nature of the liquid flowing inside, An example of the material of the O-ring (6) is fluororubber.

さらに、エルボ型のチューブ継手(1,1′)のネジ部側(A)には、配管用のブロック(7)を設けてもよい。   Further, a pipe block (7) may be provided on the threaded portion side (A) of the elbow type tube joint (1, 1 ').

これにより、片側のネジを配管によって固定することによって、反対側のネジ部を自由な方向に向けて固定することができる。   Thereby, by fixing the screw on one side with the pipe, the screw portion on the opposite side can be fixed in a free direction.

この発明は、要するに、図5に示すように、従来のエルボ形のチューブ継手(1,1′)の本体とスイベルねじ部を便宜的に利用したものであり、2重旋回の一方はエルボ形のチューブ継手のスイベルねじ部で、同継手のチューブ接続金具(C)を取り外して代わりにスイベル金具(3)を取り付けたものである。   In short, as shown in FIG. 5, the present invention uses the main body and swivel thread portion of a conventional elbow-shaped tube joint (1, 1 ') for convenience, and one of the double swivels is an elbow-type. The tube joint fitting (C) of the joint is removed and the swivel fitting (3) is attached instead.

この発明の自在継手の技術を確立し、実施することにより、産業上利用できるものである。   By establishing and implementing the technology of the universal joint of the present invention, it can be used industrially.
