由圖8及上述說明可知，該快拆連接管雖可達到快速拆裝的目的，但該插座的該第一彈簧係設置該套筒的該內套筒內，恰好位於流體流經的位置，形成該流體流程時的阻力，造成摩擦損失，如圖9所示，經測試後發現，該流體壓降最高超過80萬帕斯卡以上，確實減少該流體的速度或壓力，而有必要進一步改良之。 It can be seen from FIG. 8 and the above description that although the quick-release connecting pipe can achieve the purpose of quick disassembly and assembly, the first spring of the socket is arranged in the inner sleeve of the sleeve, just at the position where the fluid flows, The resistance during the formation of the fluid flow causes friction loss, as shown in Figure 9. After testing, it is found that the pressure drop of the fluid exceeds 800,000 Pascals at the highest, which does reduce the velocity or pressure of the fluid, and it is necessary to further improve it.

有鑑於上述快拆連接管於使用時有較大的摩擦損失，導致流體速度或壓力減少的缺點，本新型主要目的係提供一種低摩擦損失之快拆連接管及其插座。 In view of the disadvantages of the above-mentioned quick-release connecting pipe having large friction loss during use, resulting in a decrease in fluid velocity or pressure, the main purpose of the present invention is to provide a quick-release connecting pipe and its socket with low friction loss.

為達上述目的所使用的主要技術手段係令上述低摩擦損失之快拆連接管包含有：一插座，係包含有：一第一中空柱體，係包含一第一容置空間、一第一開口及一第二開口；其中該第一及第二開口係與該第一容置空間連通；一固定桿，係設置於該第一中空柱體之該第一容置空間內，且包含有一第一端及一第二端，該第一端係固定在該第一中空柱體的第一開口，該第二端係朝向該第一中空柱體的該第二開口；一套筒，係滑設於該第一中空柱體之該第一容置空間內，且包含有一孔口，該孔口係朝向該第一中空柱體的該第二開口，該套筒的一外筒面具有一固定環，以抵靠於該第一中空柱體的一內壁面，而該套筒的一內筒面係圍繞該固定桿，並與該固定桿選擇性地將該第一容置空間分隔為二；以及一第一彈簧，係同軸套設於該套筒的該外筒面，並以其一端抵靠於該套筒的該固定環，另一端抵靠於該第一中空柱體的該第一開口；以及一插接頭，係包含有：一第二中空柱體，係包含一第二容置空間、一第三開口及一第四開口，該第三開口及第四開口係與該第二容置空間連通，其中該二中空柱體係以該第三開口自該插座的該第一中空柱體的該第二開口***，以抵靠於該插座內的該套筒的該孔口，且該第三開口將該第二容置空間與該第一容置空間連通；以及一活動桿，係滑設於該第二中空柱體之該第二容置空間，並包含有一第三端及一第四端，該第三端係抵靠於該插座之該固定桿的該第二端，該第四端係透過一第二彈簧抵靠於該第二中空柱體的該第四開口，使該活動桿選擇性地關閉該第二中空柱體的該第三開口。 The main technical means used to achieve the above purpose is to make the above-mentioned low friction loss quick-release connecting pipe include: a socket, which includes: a first hollow cylinder, which includes a first accommodating space, a first an opening and a second opening; wherein the first and second openings communicate with the first accommodating space; a fixing rod is disposed in the first accommodating space of the first hollow cylinder, and includes a a first end and a second end, the first end is fixed on the first opening of the first hollow cylinder, the second end is facing the second opening of the first hollow cylinder; a sleeve is It is slidably arranged in the first accommodating space of the first hollow cylinder, and includes an orifice, the orifice is facing the second opening of the first hollow cylinder, and an outer cylindrical surface of the sleeve has a fixing ring to abut against an inner wall surface of the first hollow cylinder, and an inner cylindrical surface of the sleeve surrounds the fixing rod and selectively separates the first accommodating space from the fixing rod and a first spring, which is coaxially sleeved on the outer cylindrical surface of the sleeve, one end of which is abutted against the fixing ring of the sleeve, and the other end is abutted against the first hollow cylinder. The first opening; and a plug connector including: a second hollow cylinder including a second accommodating space, a third opening and a fourth opening, the third opening and the fourth opening are connected to The second accommodating space is communicated, wherein the two hollow cylinder systems are inserted from the second opening of the first hollow cylinder of the socket through the third opening to abut against the hole of the sleeve in the socket an opening, and the third opening communicates the second accommodating space with the first accommodating space; and A movable rod is slidably arranged in the second accommodating space of the second hollow cylinder, and includes a third end and a fourth end, the third end abuts against the fixed rod of the socket The second end, the fourth end is pressed against the fourth opening of the second hollow cylinder through a second spring, so that the movable rod selectively closes the third opening of the second hollow cylinder.

由上述說明可知，本新型低摩擦損失之快拆連接管於使用時按壓該插接頭，使該第二中空柱體推動該插座的該套筒，即可快速將該插座的該第一容置空間及該插接頭的該第二容置空間連通並供流體通過，本新型主要將該插座的該第一彈簧同軸套設於該套筒的該外筒面，使得該第一彈簧不再設置於供流體通過的該第一容置空間內；如此，當流體由該快拆連接管的該第一開口進入並通過該第一容置空間時，流體即可承受相對小的阻力，減少了該快拆連接管的內部結構對該流體造成的摩擦損失，不降低該流體的速度或壓力。 It can be seen from the above description that the quick-release connecting tube with low friction loss of the present invention presses the plug connector when in use, so that the second hollow cylinder pushes the sleeve of the socket, and the first housing of the socket can be quickly accommodated The space is communicated with the second accommodating space of the plug connector and allows fluid to pass through. The present invention mainly coaxially sleeves the first spring of the socket on the outer cylindrical surface of the sleeve, so that the first spring is no longer provided. in the first accommodating space for the fluid to pass through; in this way, when the fluid enters and passes through the first accommodating space through the first opening of the quick-release connecting pipe, the fluid can bear relatively small resistance, reducing the The friction loss of the fluid caused by the internal structure of the quick-release connecting pipe does not reduce the velocity or pressure of the fluid.

為達上述目的所使用的主要技術手段係令該插座為上述快拆連接管的插座，其可配合不同結構的插接頭使用。 The main technical means used to achieve the above-mentioned purpose is to make the socket a socket of the above-mentioned quick-release connecting pipe, which can be used with plug connectors of different structures.

由於本新型的插座係主要將該第一彈簧同軸套設於該套筒的該外筒面，令該第一彈簧不再設置於供流體通過的該第一容置空間內；如此，當流體流經該插座時，可減少第一彈簧所帶來的阻力。 Because the socket of the present invention mainly coaxially sleeves the first spring on the outer cylindrical surface of the sleeve, the first spring is no longer arranged in the first accommodating space for the fluid to pass through; When flowing through the socket, the resistance caused by the first spring can be reduced.
