Description
本発明はジョイント構造に関し、特にピン部材を設けるピンジョイントに関する。 The present invention relates to a joint structure, and more particularly to a pin joint provided with a pin member.
図５に示すように、冷媒が冷媒配管を介して空気冷却機械に注入される場合、冷媒配管５の末端にジョイント６が設けられ、空気冷却機械の接続口７に螺接され、前記ジョイント６内にピン部材６１が設けられ、前記接続口７?に弁部材７１が設けられる。前記ジョイント６は前記接続口７をねじ込んで接合する時、前記ピン部材６１は弁部材７１を開くように押し付けることで、冷媒を高圧貯蔵槽（例え、ボンベ）から前記冷媒配管５を介して輸出させ、前記接続口７内に注入する。 As shown in FIG. 5, when the refrigerant is injected into the air cooling machine via the refrigerant pipe, a joint 6 is provided at the end of the refrigerant pipe 5 and screwed into the connection port 7 of the air cooling machine. A pin member 61 is provided therein, and a valve member 71 is provided at the connection port 7 ?. When the joint 6 is screwed in and joined to the connection port 7, the pin member 61 presses the valve member 71 so that the valve member 71 is opened, so that the refrigerant is exported from the high-pressure storage tank (for example, a cylinder) through the refrigerant pipe 5. And injected into the connection port 7.
冷媒を充填する作業が完了した後、作業員は空気冷却機械の接続口７から冷媒配管５のジョイント６を取り外す必要がある。通常、作業員は手持工具或いは素手で前記ジョイント６を回転して取り外し、冷媒配管５に残留の高圧冷媒が残存するため、この時、配管内部の冷媒は前記ジョイント６から勢いよく漏らし、手に噴射することにより怪我をする可能性が高い。一方、冷媒配管５が空気冷却機械から取り外された後、漏出した冷媒の量は全体の冷媒配管５の体積量であり、この量が多いため材料が無駄になる。 After the work of filling the refrigerant is completed, the worker needs to remove the joint 6 of the refrigerant pipe 5 from the connection port 7 of the air cooling machine. Usually, an operator rotates and removes the joint 6 with a hand-held tool or bare hands, and residual high-pressure refrigerant remains in the refrigerant pipe 5. At this time, the refrigerant inside the pipe leaks vigorously from the joint 6 to the hand. There is a high possibility of injury by spraying. On the other hand, after the refrigerant pipe 5 is removed from the air cooling machine, the amount of refrigerant leaked is the volume of the entire refrigerant pipe 5, and the material is wasted because this amount is large.

本発明は上述した構造によれば、各種の圧力流体を運送する配管に使用でき、例えば、空気、油或いは冷媒などが挙げられる。実際の使用状況が図２〜図４に示されている。空気冷却機械に冷媒を注入する場合、図２に示すように、まず、前記操作部３２を回転し、前記ピン部材３は、前記凸縁部３４によって前記段差部１３３に衝止される位置まで引き出され、回転し続けて前記第１通路１３を確実に遮断させる。一方、冷媒を供給する管路４１が前記第２連結部材２の分岐管２２に連接される。そして、前記第１連結部材１の連接溝１４が空気冷却機械の接続口４２に螺着する。前記連接溝１４が前記接続口４２をしっかり締め付ける前に、前記ピン部材３は、前記第３ねじ部３１１によって前記第１通路１３の第２ねじ部１３４に締め付けたため、摩擦抵抗が生じ、作業員は前記操作部３２を回転する操作で、前記押付棒３１によって前記第１連結部材１を同時に連動して回転でき、図３に示すように、前記連接溝１４を前記接続口４２に螺嵌する。この時、前記第１連結部材１が前記第２連結部材２のスリーブ２１に挿設されているため、前記第１連結部材１が任意に回転しても、前記第２連結部材２及びそれに連接される冷媒配管４１に影響を与えない。 According to the above-described structure, the present invention can be used for piping for carrying various types of pressure fluid, and examples thereof include air, oil, or a refrigerant. The actual use situation is shown in FIGS. When injecting the refrigerant into the air cooling machine, as shown in FIG. 2, first, the operation portion 32 is rotated, and the pin member 3 is moved to a position where it is stopped by the stepped portion 133 by the convex edge portion 34. The first passage 13 is reliably shut off by being pulled out and continuing to rotate. On the other hand, a pipe 41 for supplying the refrigerant is connected to the branch pipe 22 of the second connecting member 2. Then, the connecting groove 14 of the first connecting member 1 is screwed into the connecting port 42 of the air cooling machine. Before the connecting groove 14 firmly tightens the connection port 42, the pin member 3 is fastened to the second screw portion 134 of the first passage 13 by the third screw portion 311. Is an operation of rotating the operating portion 32, and the first connecting member 1 can be simultaneously rotated by the pressing rod 31, and the connecting groove 14 is screwed into the connecting port 42 as shown in FIG. . At this time, since the first connecting member 1 is inserted into the sleeve 21 of the second connecting member 2, even if the first connecting member 1 is arbitrarily rotated, the second connecting member 2 and the connection to the second connecting member 2 are connected. This does not affect the refrigerant pipe 41 to be used.
上述した方式によれば、前記連接溝１４と前記接続口４２とをしっかり締めた後、前記第１連結部材１が前記接続口４２に固定されることによって、回転はできなくなる。前記操作部３２を更に回転し続けると、前記第３ねじ部３１１と前記第２ねじ部１３４との間の摩擦抵抗が克服でき、前記ピン部材３がアンロックされ、図４に示すように、前記第１連結部材１に対して独立に回転できる。これによって、前記第２ねじ部１３４を外し出して位置を移動させ、前記ピン部材３の押付部３３が前記連接溝１４に挿入され、且つ前記接続口４２内にある弁部材４２１を押し付ける。この時、前記ピン部材３の凸縁部３４が前記段差部１３３から離れ、冷媒配管４１が前記第２通路２３及び前記貫通孔１５を通じて前記第１通路１３に連通され、冷媒を上述の経路を経て空気冷却機械に注入できる。一方、前記ピン部材３の押付部３３が移動して前記連接溝１４に挿入され、前記弁部材４２１を開くように押し付ける時、前記操作部３２は、前記凹溝３２２がちょうど移動して前記胴部１２の一端の外部に套設され、且つ前記間隔部材１７に押し付けるようになる。 According to the above-described method, after the connection groove 14 and the connection port 42 are firmly tightened, the first connecting member 1 is fixed to the connection port 42, so that the rotation cannot be performed. If the operation part 32 is further rotated, the frictional resistance between the third screw part 311 and the second screw part 134 can be overcome, and the pin member 3 is unlocked, as shown in FIG. The first connecting member 1 can be rotated independently. As a result, the second screw portion 134 is removed to move the position, and the pressing portion 33 of the pin member 3 is inserted into the connecting groove 14 and presses the valve member 421 in the connection port 42. At this time, the convex edge portion 34 of the pin member 3 is separated from the stepped portion 133, the refrigerant pipe 41 is communicated with the first passage 13 through the second passage 23 and the through hole 15, and the refrigerant is passed through the above-described route. After that, it can be injected into an air cooling machine. On the other hand, when the pressing portion 33 of the pin member 3 is moved and inserted into the connecting groove 14 and pressed so as to open the valve member 421, the operation portion 32 is moved by the concave groove 322 and the trunk portion is moved. It is provided outside the one end of the portion 12 and is pressed against the spacing member 17.
冷媒を充填する作業を完了した後、作業員は逆の手順に従って、本発明に係るピンジョイントを前記接続口から取り外す。具体的に、作業員は、図４に示している状態で、前記操作部３２を反対方向に回転し、前記第１連結部材１の連接溝１４と前記接続口４２のねじ山との間の摩擦抵抗が前記押付棒３１と前記小径部１３２のねじ山との間の摩擦抵抗より大きいため、前記ピン部材３は、前記第２ねじ部１３４に回転して挿入し、前記押付部３３が前記接続口４２にある弁部材４２１から離れ、図３に示した状態に戻る。上述した過程において、前記操作部３２が前記間隔部材１７を押し付け、且つ前記間隔部材１７が前記胴部１２に対して動かすことができ、２つ構成の間にある摩擦抵抗が小さくなり、この過程において前記操作部３２が大きい摩擦抵抗により連動し、前記第１連結部材１を回転させることを回避できる。 After completing the work of filling the refrigerant, the worker removes the pin joint according to the present invention from the connection port according to the reverse procedure. Specifically, in the state shown in FIG. 4, the worker rotates the operation unit 32 in the opposite direction, and between the connection groove 14 of the first connection member 1 and the thread of the connection port 42. Since the frictional resistance is larger than the frictional resistance between the pressing rod 31 and the thread of the small diameter portion 132, the pin member 3 is rotated and inserted into the second threaded portion 134, and the pressing portion 33 is It leaves | separates from the valve member 421 in the connection port 42, and returns to the state shown in FIG. In the above-described process, the operation unit 32 presses the spacing member 17 and the spacing member 17 can be moved with respect to the body portion 12, and the frictional resistance between the two configurations is reduced. In this case, it is possible to avoid the operation portion 32 being interlocked by a large frictional resistance and rotating the first connecting member 1.
前記操作部３２を更に回転し続け、前記ピン部材３の凸縁部３４が前記段差部１３３に押し付けられ、前記押付棒３１を前記第２ねじ部１３４にしっかり螺着する。この時、前記ピン部材３が前記第１連結部材１に対して回転できなくなり、前記第１連結部材１が連動して回転されて、前記接続口４２から離れ、図２に示した状態に戻る。これによって、前記連接溝１４を前記接続口４２から取り外す。 The operation portion 32 continues to rotate further, the convex edge portion 34 of the pin member 3 is pressed against the stepped portion 133, and the pressing rod 31 is firmly screwed to the second screw portion 134. At this time, the pin member 3 cannot rotate with respect to the first connecting member 1, and the first connecting member 1 is rotated in conjunction with the pin member 3 to leave the connection port 42 and return to the state shown in FIG. 2. . Thus, the connecting groove 14 is removed from the connection port 42.
上述した説明により、本発明に係るピンジョイントを取付け及び取り外す過程において、作業員は前記操作部３２のみを操作して、作業のすべてのステップを完成でき、素手或いは手持工具で前記頭部１１に対する取付け或いは取り外す必要がなく、取り外す時に配管内部に残留した高圧冷媒が突然に噴出による怪我を回避できる。更に、前記操作部３２と前記連接溝１４との間に一定な安全距離を有すれば、充填する作業における安全性を更に確保できる。 According to the above description, in the process of attaching and removing the pin joint according to the present invention, the operator can complete all the steps of the operation by operating only the operation unit 32, and with respect to the head 11 with bare hands or hand-held tools. There is no need to attach or detach, and injuries due to sudden ejection of the high-pressure refrigerant remaining inside the pipe during removal can be avoided. Furthermore, if there is a certain safety distance between the operation portion 32 and the connecting groove 14, safety in the filling operation can be further ensured.
また、本発明に係るピンジョイントは、冷媒を充填する作業が完了した後、取り外そうとする際、図３に示すように、前記接続口４２にある弁部材４２１がすでに閉じられ、且つ前記ピン部材３の凸縁部３４が前記段差部１３３に押し付けされて、前記第１通路１３を遮断するため、取り外された後、配管内に漏出される残留の冷媒は前記大径部１３１にある量しかなく、作業員の怪我のリスクを低減することに加え、漏出量を減少することができ、原料の無駄使いを減少できる。 In addition, when the pin joint according to the present invention is to be removed after the operation of filling the refrigerant is completed, the valve member 421 at the connection port 42 is already closed as shown in FIG. Since the convex edge portion 34 of the pin member 3 is pressed against the stepped portion 133 to block the first passage 13, the residual refrigerant leaked into the pipe after being removed is in the large diameter portion 131. In addition to reducing the risk of injury to workers, the amount of leakage can be reduced and wasteful use of raw materials can be reduced.
