Description

本考案は、主配管を流れる流体を所望の数の分岐配管に流通させるのに用いる分岐継手に関する。 The present invention relates to a branch joint used for flowing a fluid flowing through a main pipe to a desired number of branch pipes.

従来、この種の分岐継手の構造としては、一端が開口した本管部の管壁に複数（例えば５個）の分岐孔を所定の間隔をあけて並列に設け、この分岐孔に本管部と直交する配管接続部を設けたものが知られている（例えば、特許文献１参照）。 Conventionally, this type of branch joint has a structure in which a plurality of (for example, five) branch holes are provided in parallel at predetermined intervals on the pipe wall of the main pipe part having one end opened, and the main pipe part is provided in the branch hole. There is known one provided with a pipe connection portion orthogonal to (for example, see Patent Document 1).

本管部の一端の開口に主配管を取り付け、各配管接続部に分岐配管を接続することにより、主配管を流れる流体は本管部から各配管接続部を介して各分岐配管に供給され、主配管から各分岐配管への分岐が行われるようになっている。 By attaching the main pipe to the opening at one end of the main pipe section and connecting the branch pipe to each pipe connection section, the fluid flowing through the main pipe is supplied from the main pipe section to each branch pipe via each pipe connection section. A branch from the main pipe to each branch pipe is performed.

しかしながら、上記したような分岐継手は、軽金属からなるダイカスト製品で作られている場合が多く、よって、本管部に対して設けられる配管接続部の数が予め決められている場合が多いために、接続される分岐配管の数に制約がある。すなわち、本管部に設けられた配管接続部の数よりも分岐配管の数が多いと、分岐継手を新たに別個に用意しなければならず、また、配管接続部の数よりも分岐配管の数が少なければ、使用しない配管接続部の分だけ余分なスペースをとってしまうため、省スペース化が図れないうえ、キャップ部材などによって不要な箇所の配管接続部を閉塞しなければならないため、面倒であるという問題がある。 However, branch joints as described above are often made of die-cast products made of light metal, and therefore the number of pipe connection portions provided for the main pipe portion is often determined in advance. The number of branch pipes to be connected is limited. In other words, if the number of branch pipes is larger than the number of pipe connection parts provided in the main pipe part, a new branch joint must be prepared separately, and the number of branch pipes is more than the number of pipe connection parts. If the number is small, extra space will be taken up by unused pipe connections, so space savings will not be achieved, and unnecessary pipe connections must be blocked by cap members. There is a problem that.

加えて、全ての配管接続部は、同じ方向を向くようにして本管部に設けられるのが一般的である。そのため、本管部に対して３６０度、あらゆる方向に向けて流体を分岐する必要がある場合などには、配管接続部に連結する分岐配管の配管に無理が生じたり、配管材料が多く必要になったりして、作業性が極めて悪くなるという問題もある。 In addition, it is general that all the pipe connection portions are provided in the main pipe portion so as to face the same direction. For this reason, when it is necessary to branch the fluid in all directions at 360 degrees with respect to the main pipe section, the branch pipe connected to the pipe connection section becomes unreasonable, or a large amount of piping material is required. There is also a problem that workability becomes extremely poor.

本考案は、上記した問題に着目してなされたもので、必要な方向に向けて必要な数の配管接続部を配設することが可能な分岐継手を提供することを目的とする。 The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a branch joint capable of arranging a necessary number of pipe connection portions in a necessary direction.

本考案の上記目的は、複数の継手を連結して構成される分岐継手であって、前記継手は、両端が開口し内部に流体が通過する第１の流体通路を有する筒状体と、内部に流体が通過する第２の流体通路を有しかつ一端部に配管が接続される配管接続部を備えるとともに他端部に前記筒状体を回動可能に嵌挿する開口部を備える継手本体とからなり、前記筒状体は、筒壁に径方向に貫通して前記第１の流体通路と前記第２の流体通路とを連通させる貫通孔が形成され、その一端部には連結雌部が形成されているとともに、前記開口部から突き出る他端部には隣接する前記継手の前記連結雌部と脱着可能な連結雄部が形成されており、前記連結雌部および前記連結雄部は、差し込むだけで両者の連結が可能なワンタッチ式連結構造により連結される分岐継手によって達成される。 The above-mentioned object of the present invention is a branch joint configured by connecting a plurality of joints, the joint having a cylindrical body having a first fluid passage that is open at both ends and through which fluid passes, and an internal A joint body having a second fluid passage through which a fluid passes and having a pipe connection part to which a pipe is connected at one end and an opening into which the cylindrical body is rotatably fitted at the other end. The cylindrical body is formed with a through hole that penetrates the cylindrical wall in the radial direction so as to communicate the first fluid passage and the second fluid passage, and a connecting female portion is formed at one end thereof. The other end protruding from the opening is formed with a connecting male part detachable from the connecting female part of the adjacent joint, and the connecting female part and the connecting male part are It is connected by a one-touch type connection structure that allows connection of both by simply inserting. It is achieved by 岐継 hand.

本考案の分岐継手によると、接続すべき分岐配管の数に応じた継手を用意し、これを順次連結していけば、それぞれの分岐配管に主配管からの流体を供給することができるので、余分なスペースを取ることがない。そのうえ、継手本体を筒状体に対して回動させるだけで、配管接続部の角度位置を、所望の角度位置に設定することができるので、連結する継手の数や配置角度位置の自由度が大きくなり、作業性が向上する。また、筒状体に設けられた連結雄部および連結雌部の連結構造にワンタッチ式連結構造を採用することで、筒状体相互の連結を簡便とすることができる。 According to the branch joint of the present invention, if a joint according to the number of branch pipes to be connected is prepared and connected sequentially, the fluid from the main pipe can be supplied to each branch pipe. There is no extra space. In addition, the angle position of the pipe connection portion can be set to a desired angle position simply by rotating the joint body with respect to the cylindrical body, so that the number of joints to be connected and the degree of freedom of the arrangement angle position can be increased. Increases workability. Further, by adopting a one-touch connection structure for the connection structure of the connection male part and the connection female part provided on the cylindrical body, the connection between the cylindrical bodies can be simplified.

以下、添付図面を参照しながら、本考案の実施形態について説明する。図１および図２は本考案の一実施形態である分岐継手１の外観を、図３はこの分岐継手１の縦断面図を、それぞれ示している。図示例の分岐継手１は、主配管（図示せず）を流れる流体（気体および液体）を所望の数の分岐配管（図示せず）に流通させるために用いるものである。この分岐継手１は、基本的には、分岐配管を接続可能な配管接続部５を備えた複数の継手２を横一列に連結し、主配管を接続可能なコネクタ部材７を一端の継手２に、キャップ部材８を他端の継手２に、それぞれ取り付けて構成されたものである。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 show the appearance of a branch joint 1 according to an embodiment of the present invention, and FIG. 3 shows a longitudinal sectional view of the branch joint 1. The branch joint 1 in the illustrated example is used for circulating fluid (gas and liquid) flowing through a main pipe (not shown) to a desired number of branch pipes (not shown). The branch joint 1 basically includes a plurality of joints 2 each having a pipe connection portion 5 to which a branch pipe can be connected, and a connector member 7 to which a main pipe can be connected to the joint 2 at one end. The cap member 8 is attached to the joint 2 at the other end, respectively.

各継手２は、両端に開口を有する円筒状の筒状体３と、一端部に配管接続部５を備える継手本体４とからなる。継手本体４は、図３〜図５に示すように、筒状の基部４０の周面に略円筒状の本体部４１の基端が一体に突設された構成のものであり、本体部４１の先端に前記配管接続部５が一体形成されている。 Each joint 2 includes a cylindrical tubular body 3 having openings at both ends, and a joint body 4 having a pipe connection portion 5 at one end. As shown in FIGS. 3 to 5, the joint main body 4 has a configuration in which a base end of a substantially cylindrical main body portion 41 is integrally projected on a peripheral surface of a cylindrical base portion 40. The pipe connection part 5 is integrally formed at the tip of the.

基部４０は、外形が略正方形状に形成されており、中央に筒状体３が回動自由に嵌挿される円形の開口部４２を有している。この開口部４２は、前面および後面に開口し、前記筒状体３の外形に沿うように形成されている。 The base 40 is formed in a substantially square shape, and has a circular opening 42 into which the cylindrical body 3 is rotatably inserted. The opening 42 opens to the front and rear surfaces and is formed along the outer shape of the cylindrical body 3.

本体部４１の内部は、流体の通路（以下、「第２の流体通路４３」という。）となっている。この第２の流体通路４３は、前記開口部４２に連通しているとともに、本体部４１の先端まで延在している。本体部４１先端の配管接続部５は、本実施形態では、分岐配管に取り付けられたプラグ（図示せず）を差し込むだけで両者の連結が可能な、いわゆる公知のワンタッチ式連結構造となっており、両端が開放された外筒５０と、外筒５０内に嵌挿された内筒５１と、外筒５０の外周面に嵌合するスリーブ５２と、外筒５０とスリーブ５２との間に設けられたコイルバネ５３と、外筒５０の筒壁に径方向に貫通するように形成された複数の貫通溝５４内に径方向に出没可能に設けられた複数のロックボール５５とで構成されている。 The inside of the main body 41 is a fluid passage (hereinafter referred to as “second fluid passage 43”). The second fluid passage 43 communicates with the opening 42 and extends to the tip of the main body 41. In this embodiment, the pipe connection part 5 at the tip of the main body part 41 has a so-called known one-touch type connection structure in which both can be connected by simply inserting a plug (not shown) attached to the branch pipe. The outer cylinder 50 having both ends opened, the inner cylinder 51 fitted and inserted into the outer cylinder 50, the sleeve 52 fitted to the outer peripheral surface of the outer cylinder 50, and the outer cylinder 50 and the sleeve 52 are provided between the outer cylinder 50 and the sleeve 52. And a plurality of lock balls 55 provided in a plurality of through grooves 54 formed so as to penetrate through the cylindrical wall of the outer cylinder 50 in a radial direction. .

外筒５０は、その下端が前記本体部４１に接合されており、外筒５０の下端内部（本体部４１の先端内部）に固着されたガイド５６に内筒５１が上下動自在に挿通支持されて、内筒５１はほぼ真っ直ぐに上下動するようになっている。内筒５１とガイド５６との間には、圧縮バネ５７が配備され、そのバネ力によって内筒５１を常時、上方へ付勢している。内筒５１の下端には、分岐配管のプラグの挿入時に、プラグが当接して内筒５１を下方に押圧する押圧面５１Ａが設けられている。 The lower end of the outer cylinder 50 is joined to the main body 41, and the inner cylinder 51 is inserted and supported by a guide 56 fixed inside the lower end of the outer cylinder 50 (inside the tip of the main body 41) so as to be movable up and down. Thus, the inner cylinder 51 moves up and down almost straight. A compression spring 57 is provided between the inner cylinder 51 and the guide 56, and the inner cylinder 51 is always urged upward by the spring force. At the lower end of the inner cylinder 51, there is provided a pressing surface 51A that abuts the plug and presses the inner cylinder 51 downward when the plug of the branch pipe is inserted.

スリーブ５２は、外筒５０上端の外周面に上下方向に摺動自在に取り付けられており、コイルバネ５３のバネ力によって常時、上方へと付勢されている。スリーブ５２の内周面は、外筒５０の外周面上を摺動して各ロックボール５５を内方へ向けて押し込む押込面５２Ａとなっており、その上部には各ロックボール５５が嵌り込むことが可能な凹部５２Ｂが全周にわたって形成されている。 The sleeve 52 is attached to the outer peripheral surface of the upper end of the outer cylinder 50 so as to be slidable in the vertical direction, and is always urged upward by the spring force of the coil spring 53. The inner peripheral surface of the sleeve 52 is a pressing surface 52A that slides on the outer peripheral surface of the outer cylinder 50 and pushes each lock ball 55 inward, and each lock ball 55 is fitted on the upper surface thereof. The recessed part 52B which can be formed is formed over the perimeter.

各ロックボール５５は、球状のものであり、分岐配管のプラグの未挿入時には、スリーブ５２の凹部５２Ｂに嵌まり込み、スリーブ５２の内周面と内筒５１の外周面との間で挟持されて、内方への移動が規制されている。 Each lock ball 55 is spherical and fits into the recess 52B of the sleeve 52 when the branch pipe plug is not inserted, and is sandwiched between the inner peripheral surface of the sleeve 52 and the outer peripheral surface of the inner cylinder 51. Inward movement is restricted.

分岐配管のプラグが配管接続部５の内筒５１内に挿入されると、プラグの先端が内筒５１の押圧部５１Ａと当接して、プラグにより内筒５１が圧縮バネ５７のバネ力に抗して下方に押される結果、スリーブ５２がコイルバネ５３のバネ力により押されて上方に移動し、その押圧面５２Ａにより各ロックボール５５を内方に押圧移動させる。これにより、各ロックボール５５が前記プラグの外周面に形成された施錠凹部（図示せず）に嵌入し、スリーブ５２の押圧面５２Ｂによって前記施錠凹部内に保持されることで、前記プラグは配管接続部５から抜け出るのが阻止されるようになっている。 When the plug of the branch pipe is inserted into the inner cylinder 51 of the pipe connection portion 5, the tip of the plug comes into contact with the pressing portion 51 </ b> A of the inner cylinder 51, and the inner cylinder 51 resists the spring force of the compression spring 57 by the plug. As a result, the sleeve 52 is pushed by the spring force of the coil spring 53 and moved upward, and the lock balls 55 are pushed and moved inward by the pushing surface 52A. As a result, each lock ball 55 is fitted into a locking recess (not shown) formed on the outer peripheral surface of the plug, and is held in the locking recess by the pressing surface 52B of the sleeve 52, whereby the plug is connected to the piping. The connection part 5 is prevented from coming out.

なお、図中、５８は、内筒５１の内周面に嵌め込まれたＯリングであり、このＯリング５８が、プラグの挿入時に、プラグの外周面と内筒５１の内周面との隙間を塞ぐことで、プラグと内筒５１との気密性（または液密性）を高めている。 In the figure, 58 is an O-ring fitted into the inner peripheral surface of the inner cylinder 51, and this O-ring 58 is a gap between the outer peripheral surface of the plug and the inner peripheral surface of the inner cylinder 51 when the plug is inserted. As a result, the air tightness (or liquid tightness) between the plug and the inner cylinder 51 is enhanced.

一方、この状態から、スリーブ５２をコイルバネ５３のバネ力に抗して下方に移動させると、各ロックボール５５は、外方に移動し、前記プラグの施錠凹部から抜け出してスリーブ５２の凹部５２Ｂに嵌まり込むようになるので、前記プラグは配管接続部５から引き抜きが可能な状態となる。 On the other hand, when the sleeve 52 is moved downward against the spring force of the coil spring 53 from this state, each lock ball 55 is moved outward and comes out of the locking recess of the plug and into the recess 52B of the sleeve 52. Since the plug is inserted, the plug can be pulled out from the pipe connection portion 5.

なお、配管接続部５の構造は、上記のワンタッチ式連結構造に限られるものではなく、例えば、図８および図９に示すように、本体部４１の端面から円筒状の筒部５９を突設させ、この筒部５９を分岐配管内に挿入して両者をクリップなどの止着手段で連結固定するといったものや、図１０および図１１に示すように、筒部６０を、先端側から基端側に向けて径が広がるテーパ状体６１を複数連続させた形状とし、このテーパ状体６１に形成された段状の係止部６２によって、連結する分岐配管の抜け止めをするようにしたものの他、図１２および図１３に示すように、筒部６３を内筒部６４および外筒部６５を有する二重筒構造に構成して、分岐配管を内筒部６４と外筒部６５との間に嵌め付け固定するといったものなど、種々の構造を採用することができる。 Note that the structure of the pipe connection portion 5 is not limited to the one-touch connection structure described above. For example, as shown in FIGS. 8 and 9, a cylindrical tube portion 59 projects from the end surface of the main body portion 41. The cylindrical portion 59 is inserted into the branch pipe and both are connected and fixed by a fastening means such as a clip. As shown in FIGS. 10 and 11, the cylindrical portion 60 is connected to the proximal end from the distal end side. A plurality of tapered bodies 61 whose diameters increase toward the side are formed in a continuous shape, and stepped locking portions 62 formed on the tapered bodies 61 are used to prevent the branch pipes to be connected from coming off. In addition, as shown in FIGS. 12 and 13, the cylindrical portion 63 is configured in a double cylindrical structure having an inner cylindrical portion 64 and an outer cylindrical portion 65, and a branch pipe is formed by the inner cylindrical portion 64 and the outer cylindrical portion 65. Various structures such as fitting and fixing in between are adopted. It can be.

さらに、このような配管接続部５の構造が異なる様々なタイプの継手本体４を複数種準備しておき、接続すべき複数の分岐配管それぞれの接続方法に応じた継手本体４を適宜選択して、これらを組み合わせるようにすることにより、使用状況に合致した分岐継手１を構成することが可能になる。 Further, a plurality of types of various types of joint main bodies 4 having different structures of the pipe connecting portions 5 are prepared, and the joint main bodies 4 corresponding to the connection methods of the plurality of branch pipes to be connected are appropriately selected. By combining these, it becomes possible to configure the branch joint 1 that matches the use situation.

筒状体３は、図３、図６および図７に示すように、両端が開放された中空の円筒体であり、継手本体４の開口部４２に回動可能に嵌挿される筒壁部３０と、筒壁部３０の一方の端部（前端部）側の外周面に形成されたフランジ部３１とを備えている。このフランジ部３１は、継手本体４の基部４０と略同一外径のものであり、フランジ部３１の一方の端面が、継手本体４の基部４０の一方の端面に回動自在に当接している。 As shown in FIGS. 3, 6, and 7, the cylindrical body 3 is a hollow cylindrical body that is open at both ends, and is a cylindrical wall portion 30 that is rotatably inserted into the opening 42 of the joint body 4.

An annular groove portion 33 is formed on the outer peripheral surface on the other end (rear end portion) side of the cylindrical wall portion 30, and the cylindrical wall portion 30 has a diameter at an equiangular position in the groove portion 33. A plurality of (two in the illustrated example) through holes 34 penetrating in the direction are provided.

この溝部３３および貫通孔３４は、第１の流体通路３２の一部をなすもので、筒壁部３０が継手本体４の開口部４２内に嵌挿されたときに、第１の流体通路３２は、この貫通孔３４および溝部３３を介して継手本体４の第２の流体通路４３と連通するようになっている。 The groove 33 and the through hole 34 form a part of the first fluid passage 32, and when the cylindrical wall portion 30 is fitted into the opening 42 of the joint body 4, the first fluid passage 32. Is communicated with the second fluid passage 43 of the joint body 4 through the through hole 34 and the groove 33.

なお、図中、７３は、コネクタ部材７の係合雌ネジ部７２と継手２の雄ネジ部３９との連結部からの流体の漏れを防止するために、雄ネジ部３９の基端部の外周面に装着されたＯリングである。 In the drawing, reference numeral 73 denotes a base end portion of the male screw portion 39 in order to prevent fluid leakage from a connecting portion between the engaging female screw portion 72 of the connector member 7 and the male screw portion 39 of the joint 2. An O-ring mounted on the outer peripheral surface.

コネクタ部材７の配管取付部７０の構造は、本実施形態では、両面が開放された筒状をなし、分岐配管内に挿入して両者をクリップなどの止着手段で固定することにより、分岐配管と連結される構造になっているが、このような構造に限られるものではない。例えば、上述した継手２の配管接続部５と同様、配管取付部７０を、内筒部および外筒部を有する二重筒構造に構成して分岐配管を内筒部と外筒部との間に嵌め付け固定するといったものや、先端側から基端側に向けて径が広がるテーパ状体を複数連続した形状とし、テーパ状体の段状の係止部により連結時における主配管の抜け止めをするようにしたもの、さらには、主配管に取り付けられたプラグ（図示せず）を差し込むだけで両者の連結が可能な、いわゆるワンタッチ式連結構造など、種々の構造を採用することができる。 In the present embodiment, the structure of the pipe mounting portion 70 of the connector member 7 is formed in a cylindrical shape in which both sides are opened, and is inserted into the branch pipe and fixed by a fastening means such as a clip. However, it is not limited to such a structure. For example, similarly to the pipe connection part 5 of the joint 2 described above, the pipe attachment part 70 is configured in a double cylinder structure having an inner cylinder part and an outer cylinder part, and the branch pipe is arranged between the inner cylinder part and the outer cylinder part. The main pipe is prevented from coming off at the time of connection by connecting a plurality of tapered bodies with diameters extending from the distal end side to the proximal end side and connecting them with a stepped locking portion of the tapered body. In addition, various structures such as a so-called one-touch connection structure that can be connected by simply inserting a plug (not shown) attached to the main pipe can be employed.

さらに、このような配管取付部７０の構造が異なる様々なタイプのコネクタ部材７を複数種準備しておき、接続すべき主配管との接続方法に応じたコネクタ部材７を継手２に取り付けるようにすることで、使用状況に合致した分岐継手１を構成することが可能になる。 Further, a plurality of various types of connector members 7 having different structures of the pipe mounting portion 70 are prepared, and the connector member 7 corresponding to the connection method with the main pipe to be connected is attached to the joint 2. By doing so, it becomes possible to constitute the branch joint 1 that matches the use situation.

キャップ部材８は、複数個連設された継手２の第１の流体通路３２を閉塞するためのものであり、図１〜図３に示すように、分岐継手１の他端の継手２の雌ネジ部３８に脱着可能に取り付けられている。このキャップ部材８は、平板部８０の一方の端面に前記雌ネジ部３８と螺合する係合雄ネジ部８１が一体に突設された構成のものであり、係合雄ネジ部８１を継手２の雌ネジ部３８に係合することにより、継手２に容易に連結されるようになっている。 The cap member 8 is for closing the first fluid passage 32 of the joint 2 provided in series. As shown in FIGS. 1 to 3, the female of the joint 2 at the other end of the branch joint 1 is used. The screw part 38 is detachably attached. The cap member 8 has a configuration in which an engaging male screw portion 81 that is screwed into the female screw portion 38 is integrally formed on one end surface of the flat plate portion 80, and the engaging male screw portion 81 is connected to the joint member 8. By engaging with the female thread portion 38 of the second, it is easily connected to the joint 2.

なお、図中、８２は、キャップ部材８の係合雄ネジ部８１と継手２の雌ネジ部３８との連結部からの流体の漏れを防止するために、係合雄ネジ部８１の基端部の外周面に装着されたＯリングである。 In the figure, reference numeral 82 denotes a base end of the engaging male screw portion 81 in order to prevent fluid leakage from a connecting portion between the engaging male screw portion 81 of the cap member 8 and the female screw portion 38 of the joint 2. It is an O-ring mounted on the outer peripheral surface of the part.

本考案に係る分岐継手１は、基本的には以上のように構成されるものであり、次にその作用並びに効果について説明する。まず、流体を流通させる分岐配管の数に応じて、継手２を必要な個数だけ連結する。すなわち、ある一つの継手２の筒状体３の雌ネジ部３８に、他の一つの継手２の雄ネジ部３９を順次係合させることで、分岐配管に対応する数の継手２を次々に連結する。これにより、複数の継手２の第１の流体通路３２が互いに同軸上に連結されて連通して複数の継手本体４が横並びに並設される。 The branch joint 1 according to the present invention is basically configured as described above. Next, its operation and effects will be described. First, a required number of joints 2 are connected in accordance with the number of branch pipes through which fluid flows. That is, by sequentially engaging the male threaded portion 39 of the other joint 2 with the female threaded portion 38 of the tubular body 3 of one joint 2, the number of joints 2 corresponding to the branch pipes is successively established. Link. Accordingly, the first fluid passages 32 of the plurality of joints 2 are coaxially connected to each other and communicate with each other so that the plurality of joint bodies 4 are arranged side by side.

このとき、各継手２の角度位置は、筒状体３に対して継手本体４を回動させることにより、任意に選択可能となっているので、配管接続部５を分岐配管に無理なく装着させることができる。所望の数の継手２を連結させると、一端の継手２の雄ネジ部３９に主配管を接続するためのコネクタ部材７を取り付けるとともに、他端の継手２の雌ネジ部３８にキャップ部材８を取り付けて、各継手２の第１の流体通路３２を閉塞する。そして、コネクタ部材７に主配管を、各継手２の配管接続部５に対応する分岐配管を、それぞれ接続することにより、各分岐配管に主配管を流れる流体を好適に供給することが可能となる。 At this time, the angular position of each joint 2 can be arbitrarily selected by rotating the joint body 4 with respect to the tubular body 3, so that the pipe connecting portion 5 can be easily attached to the branch pipe. be able to. When a desired number of joints 2 are coupled, the connector member 7 for connecting the main pipe is attached to the male threaded portion 39 of the joint 2 at one end, and the cap member 8 is attached to the female threaded portion 38 of the joint 2 at the other end. Attach and close the first fluid passage 32 of each joint 2. Then, by connecting the main pipe to the connector member 7 and the branch pipe corresponding to the pipe connecting portion 5 of each joint 2, it is possible to suitably supply the fluid flowing through the main pipe to each branch pipe. .

上記した構成の分岐継手１によると、接続すべき分岐配管の数に応じた継手２を用意し、これを順次連結していけば、それぞれの分岐配管に主配管からの流体を供給することができるので、余分なスペースを取ることなく、また、継手本体４を筒状体３に対して回動させるだけで、各継手２、つまり、配管接続部５の角度位置を、所望の角度位置に設定することができるので、連結する継手２の数や配置角度位置の自由度が大きくなり、作業性が向上する。 According to the branch joint 1 having the above-described configuration, if the joints 2 corresponding to the number of branch pipes to be connected are prepared and sequentially connected, the fluid from the main pipe can be supplied to each branch pipe. Therefore, the angular position of each joint 2, that is, the pipe connection portion 5, can be set to a desired angular position by simply rotating the joint body 4 with respect to the tubular body 3 without taking extra space. Since it can be set, the number of joints 2 to be connected and the degree of freedom of the arrangement angle position are increased, and workability is improved.

以上、本考案の一実施形態について説明したが、本考案の具体的な態様は、上記実施形態に限定されるものではない。例えば、本実施形態では、コネクタ部材７を分岐継手１の一端の継手２の雄ネジ部３９に、キャップ部材８を他端の継手２の雌ネジ部３８に、それぞれ取り付けているが、コネクタ部材７を他端の継手２の雌ネジ部３８に、キャップ部材８を一端の継手２の雄ネジ部３９に、それぞれ取り付けるように構成してもよい。 As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment. For example, in this embodiment, the connector member 7 is attached to the male threaded portion 39 of the joint 2 at one end of the branch joint 1, and the cap member 8 is attached to the female threaded portion 38 of the joint 2 at the other end. 7 may be attached to the female screw portion 38 of the joint 2 at the other end, and the cap member 8 may be attached to the male screw portion 39 of the joint 2 at the one end.

また、キャップ部材８に代わって、配管接続用のコネクタ部材７を他端の継手２の雌ネジ部３８にも取り付けるように構成することで、分岐継手１に連結する分岐配管の数を１つ増加させるようにしても構わない。 Further, instead of the cap member 8, the connector member 7 for pipe connection is also attached to the female screw portion 38 of the joint 2 at the other end, so that the number of branch pipes connected to the branch joint 1 is one. You may make it increase.
