Description

本考案は、特にエアコンプレッサとエア工具とを安全に結合させて空気通路を作るための、容易に着脱することができるクイック継ぎ手に関するものである。   The present invention particularly relates to an easily attachable and detachable quick joint for safely connecting an air compressor and an air tool to create an air passage.

従来のクイック継ぎ手は、エア工具に応用されるものであり、そのエア工具は、エアコンプレッサからの高圧気体に駆動され、空気注入端に雄コネクタが設置されている。また、該クイック継ぎ手には、エアコンプレッサに連結されたパイプが設置され、エア工具の雄コネクタと連結することにより空気通路が形成されている。   The conventional quick joint is applied to an air tool, and the air tool is driven by high-pressure gas from an air compressor, and a male connector is installed at an air injection end. The quick joint is provided with a pipe connected to an air compressor, and an air passage is formed by connecting with a male connector of an air tool.

従来のクイック継ぎ手は、雄コネクタと連結する前に、内部の空気通路が内部に設置された制御弁に封鎖され、空気の通過を阻止するものであり、雄コネクタと連結すると、雄コネクタの前端が制御弁を押圧して空気通路を開け、空気の通過を可能とする。   In the conventional quick joint, before the connection with the male connector, the internal air passage is blocked by a control valve installed inside to prevent the passage of air. Presses the control valve to open the air passage and allow the passage of air.

さらに、従来のクイック継ぎ手と雄コネクタは、互いに安定に連結させるため、クイック継ぎ手内周面に複数のボールが設置されると共に、該ボールと対応する、雄コネクタ外周面に環状の係合凹部が凹設され、これにより、従来のクイック継ぎ手の内部に挿入する時に、係合凹部がボールに対応すると共に、互いに係合するように、クイック継ぎ手と安定に連結することができる。   Further, in order to stably connect the conventional quick joint and the male connector, a plurality of balls are installed on the inner peripheral surface of the quick joint, and an annular engagement recess is formed on the outer peripheral surface of the male connector corresponding to the ball. The concave portion is provided so that when inserted into the conventional quick joint, the engaging concave portion corresponds to the ball and can be stably connected to the quick joint so as to engage with each other.

しかしながら、従来のエア工具を使用する時は、エアコンプレッサが高圧気体を提供し続けるため、雄コネクタがクイック継ぎ手と連結する前に、クイック継ぎ手の制御弁が雄コネクタの前端に押圧されて通路となり、高圧気体が噴出して雄コネクタを押し出してしまうと、装着し直さなければならないので、使用上、非常に不便であった。また、力が足りない人の場合、装着できないこともあった。   However, when using a conventional air tool, the air compressor will continue to provide high pressure gas, so the control valve of the quick joint is pressed against the front end of the male connector before the male connector connects with the quick joint to become a passage. When the high pressure gas is ejected and the male connector is pushed out, it must be remounted, which is very inconvenient in use. In addition, in the case of a person with insufficient power, it may not be able to be worn.

さらに、雄コネクタをクイック継ぎ手から外す時には、クイック継ぎ手のボールを径方向の外側へ移動させれば、雄コネクタをクイック継ぎ手から引き出すことができるが、雄コネクタがクイック継ぎ手から外れる時には、クイック継ぎ手の制御弁が元の箇所に復位する間も、高圧気体が噴出し続けることから、雄コネクタを飛び出させてしまうので、手でパイプをしっかり持たなければ、高圧気体の強い力でパイプが振られ、危険な状態が発生する恐れがある。   Furthermore, when the male connector is disconnected from the quick joint, the male connector can be pulled out of the quick joint by moving the quick joint ball radially outward, but when the male connector is disconnected from the quick joint, Since the high-pressure gas continues to blow out while the control valve is restored to the original position, the male connector will pop out, so if you do not hold the pipe firmly by hand, the pipe will be shaken by the strong pressure of the high-pressure gas, Dangerous situations may occur.

特許文献1乃至特許文献3に示すように、従来の「安全クイック継ぎ手」は、本考案と同一の創作者が考案したことによって、雄コネクタがスムーズにクイック継ぎ手から外れることができるが、スムーズに安全な連結が未だ期待されている。   As shown in Patent Document 1 to Patent Document 3, the conventional “safety quick joint” was devised by the same creator as the present invention, so that the male connector can be smoothly detached from the quick joint. Safe connection is still expected.

従来のクイック継ぎ手は、雄コネクタと連結する時に、エアコンプレッサからの高圧気体が雄コネクタを押し出すことから、装着し直さなければならない問題があり、使用上、
非常に不便であった。さらに、雄コネクタがクイック継ぎ手から外れる時に、雄コネクタが高圧気体によって飛び出すので、危険な状態が発生する恐れがあった。
The conventional quick joint has a problem that the high-pressure gas from the air compressor pushes out the male connector when it is connected to the male connector.
It was very inconvenient. Further, when the male connector is detached from the quick joint, the male connector pops out by the high-pressure gas, which may cause a dangerous state.

図5及び図6に示すように、本考案に係る安全クイック継ぎ手を使用する時は、前端外
周面に凹設される係合凹部(71)を備える雄コネクタ(70)と連結されると共に、該雄コネクタ(70)を介してエア工具と連結される。このように、前記雄コネクタ(70)との連結には、以下に示すように二つの段階がある。
As shown in FIGS. 5 and 6, when the safety quick joint according to the present invention is used, it is connected to a male connector (70) having an engaging recess (71) recessed in the outer peripheral surface of the front end, It is connected to the air tool through the male connector (70). Thus, the connection with the male connector (70) has two stages as shown below.

図5に示すように、雄コネクタ(70)の前端は、第二位置決め部品(40)に挿入することによって、内押圧リング(53)と円柱管(54)を押圧して、当接スプリング(31)を圧縮させる。そして、外押圧リング(51)は、押圧スプリング(52)に押圧されて第二位置決め部品(40)の外フランジ(42)に向かって移動する。また、雄コネクタ(70)の前端は、係合凹部(71)が複数の第二ボール(45)に当接するまで第二位置決め部品(40)の内部を移動し、複数の第二ボール(45)が外押圧リング(51)内周面に押圧されて係合凹部(71)に係合することにより、第一段階の連結が完成する。
尚、この時、制御弁(30)は移動せず、第一位置決め部品(20)の密閉環体(21)と気密的に当接されている状態であり、エアコンプレッサ(符号なし)からの高圧気体による衝撃を受けないので、雄コネクタ(70)が外れることはない。
As shown in FIG. 5, the front end of the male connector (70) is inserted into the second positioning component (40) to press the inner pressing ring (53) and the cylindrical tube (54), and a contact spring ( 31) is compressed. The outer pressing ring (51) is pressed by the pressing spring (52) and moves toward the outer flange (42) of the second positioning component (40). Further, the front end of the male connector (70) moves inside the second positioning component (40) until the engaging recess (71) contacts the plurality of second balls (45), and the plurality of second balls (45) ) Is pressed by the inner peripheral surface of the outer pressing ring (51) and engaged with the engaging recess (71), thereby completing the first-stage connection.
At this time, the control valve (30) does not move and is in a state of being in airtight contact with the sealed annular body (21) of the first positioning component (20), and from the air compressor (not indicated). The male connector (70) does not come off because it is not impacted by the high pressure gas.

図6を示すように、雄コネクタ(70)の前端は、本体(10)に向かって移動することにより、係合凹部(71)に係合された複数の第二ボール(45)を介して第二位置決め部品(40)を本体(10)に向かって移動させる。これにより、制御弁(30)は、当接スプリング(31)が空気室(121)及び空気注入管(11)と連通するまで第二位置決め部品(40)に押圧され、本体(10)と連通状態となる。また、制御弁(30)が第一位置決め部品(20)と本体(10)の内部に押し込まれる時に、第一位置決め部品(20)の複数の第一ボール(25)が、前カバー体(61)の傾斜面部(613)に押圧されて制御弁(30)の位置決め凹部(35)に係合し、安定に第一位置決め部品(20)と係合することにより、第二段階の連結が完成する。   As shown in FIG. 6, the front end of the male connector (70) moves toward the main body (10) and thereby passes through the plurality of second balls (45) engaged with the engagement recesses (71). The second positioning component (40) is moved toward the main body (10). Thereby, the control valve (30) is pressed by the second positioning component (40) until the contact spring (31) communicates with the air chamber (121) and the air injection pipe (11), and communicates with the main body (10). It becomes a state. Further, when the control valve (30) is pushed into the first positioning component (20) and the main body (10), the plurality of first balls (25) of the first positioning component (20) are moved to the front cover body (61). ) Is engaged with the positioning recess (35) of the control valve (30) and is stably engaged with the first positioning component (20), thereby completing the second-stage connection. To do.

このように、本考案に係る安全クイック継ぎ手は、2段階式で雄コネクタ(70)と連結し、第一段階では、雄コネクタ(70)を第二位置決め部品(40)に挿入させて複数の第二ボール(45)に係合させ、制御弁(30)を押圧しないので、エアコンプレッサ(符号なし)からの高圧気体による衝撃を受けずに容易に雄コネクタ(70)を連結するこができる。一方、第二段階は、雄コネクタ(70)を本体(10)に向かって移動させて制御弁(30)を押圧し、制御弁(30)を第一位置決め部品(20)と本体(10)の内部に押し込む時に、複数の第一ボール(25)に係合させることにより、制御弁(30)を安定に第一位置決め部品(20)と連結させると共に、制御弁(30)を空気室(121)及び空気注入管(11)と連通させる。   As described above, the safety quick joint according to the present invention is connected to the male connector (70) in a two-stage manner, and in the first stage, the male connector (70) is inserted into the second positioning component (40), and a plurality of the quick connectors are connected. Since the control valve (30) is not pressed by engaging with the second ball (45), the male connector (70) can be easily connected without being shocked by the high pressure gas from the air compressor (not shown). . On the other hand, in the second stage, the male connector (70) is moved toward the main body (10) to press the control valve (30), and the control valve (30) is moved to the first positioning component (20) and the main body (10). By engaging the first balls (25), the control valve (30) is stably connected to the first positioning component (20) and the control valve (30) is connected to the air chamber ( 121) and the air injection pipe (11).

更に、本考案に係る安全クイック継ぎ手は、雄コネクタ(70)を外す時に、第二位置決め部品(40)に向かって雄コネクタ(70)を引いて、制御弁(30)の前端の詰まりリング(32)を第一位置決め部品(20)の密閉環体(21)と当接する気密な状態に戻し、そして、第二位置決め部品(40)から外すように雄コネクタ(70)を引き出す。この時、エアコンプレッサ(符号なし)からの高圧気体の流れは停止しているので、雄コネクタ(70)が高圧気体に押し出されることを防ぎ、安全クイック継ぎ手からスムーズに取り外すことができる。   Furthermore, the safety quick joint according to the present invention is configured such that when the male connector (70) is removed, the male connector (70) is pulled toward the second positioning component (40), and the clogging ring ( 32) is returned to an airtight state in contact with the sealing ring (21) of the first positioning component (20), and the male connector (70) is pulled out so as to be disconnected from the second positioning component (40). At this time, since the flow of the high-pressure gas from the air compressor (not indicated) is stopped, the male connector (70) can be prevented from being pushed out by the high-pressure gas, and can be smoothly removed from the safety quick joint.

本考案は上記の構成を有するので、雄コネクタの着脱をスムーズに行うことができる。   Since the present invention has the above-described configuration, the male connector can be smoothly attached and detached.
