Description

活動管接頭Flexible pipe joint

本創作係有關於一種組裝快速、降低成本及不易分離之活動管接頭構造。This creation is about a movable pipe joint structure that is quick to assemble, reduce cost, and difficult to separate.

目前一般所使用之活動管接頭，係為專供兩管體間連接使用之一種接頭，又為了配合不同的工作環境及作業特性，其係使兩端連接的管體或噴頭得以活動相對旋轉，藉以避免兩管體間相互牽動，以致造成扭曲、捲繞之情事發生，可確保管體內部之通暢者。The movable pipe joint generally used at present is a joint specially used for the connection between two pipe bodies. In order to match different working environments and operating characteristics, it is to make the pipe bodies or nozzles connected at both ends move and rotate relative to each other. In order to avoid the mutual influence between the two tubes, which may cause twisting and winding, it can ensure the smoothness of the inside of the tube.

習知活動管接頭之構造，如第七圖所示，係由一固定頭A及一插接頭B所組成，其中固定頭A上設有一裝填孔A1，該裝填孔A1連通至內壁環設一容珠槽A2，藉由該裝填孔A1填入複數的鋼珠C，藉以該容珠槽A2內佈滿該等鋼珠C，然後再以一直徑較大的另一封閉鋼珠C1予以迫緊塞入該裝填孔A1內，使該等鋼珠C不會掉出，利用該等鋼珠C設置於該固定頭A及該插接頭B之間，使得該固定頭A及該插接頭B可以相對旋轉。The structure of the conventional movable pipe joint, as shown in Figure 7, is composed of a fixed head A and a plug-in joint B. The fixed head A is provided with a filling hole A1 which is connected to the inner wall ring. A ball-holding groove A2, through the filling hole A1, is filled with a plurality of steel balls C, so that the ball-holding groove A2 is filled with the steel balls C, and then a closed steel ball C1 with a larger diameter is used to tighten it Insert into the filling hole A1 so that the steel balls C will not fall out. The steel balls C are arranged between the fixed head A and the plug connector B so that the fixed head A and the plug connector B can rotate relatively.

惟由於該等鋼珠C係一顆一顆的由該裝填孔A1填入至該容珠槽A2，因此相當耗費作業時間，以及增加鋼珠製造成本，而且該等鋼珠C與該固定頭A及該插接頭B之間的接觸面積小，因此卡掣力不足，造成該固定頭A及該插接頭B之間容易鬆脫，而且一旦該固定頭A及該插接頭B之間的流體壓力過大時，也會造成該封閉鋼珠C1被彈出，使得該等鋼珠C掉出，同樣會使得該固定頭A及該插接頭B鬆脫，而失去作用。However, because the steel balls C are filled one by one from the filling hole A1 to the ball receiving groove A2, it takes a lot of time and increases the manufacturing cost of the steel balls. Moreover, the steel balls C and the fixed head A and the The contact area between the plug connector B is small, so the clamping force is insufficient, causing the fixed head A and the plug connector B to easily loosen, and once the fluid pressure between the fixed head A and the plug connector B is too large , It will also cause the closed steel ball C1 to be ejected, causing the steel balls C to fall out, and also cause the fixed head A and the plug connector B to loosen and lose their function.

因此有中華民國94年3月11日所公告之新型第M259101號「活動轉頭之構造」專利案，其係揭露：一固定頭及一插接頭所組成，其中固定頭內部穿設有一出水孔及一穿套孔，穿套孔前端孔口處鑽設出一錐形套口，並於後端設有與之相通之裝填孔及注油孔，該裝填孔及注油孔間係相隔180度間角穿設，以分別供裝填、退出鋼珠或注入黃油對鋼珠施以潤滑、防銹之用。再插接頭係自穿套孔後端之孔口穿入，其前緣削設形成一圓錐狀之貼靠面，該貼靠面適可貼於穿套孔前端錐形套口之內面，使之得循穿套孔中心活動旋轉。Therefore, there is a new patent case No. M259101 "Structure of movable head" announced by the Republic of China on March 11, 1994, which discloses: a fixed head and a plug connector, in which a water outlet hole is penetrated inside the fixed head And a piercing hole. A tapered socket is drilled at the front end of the piercing hole, and a filling hole and an oil injection hole communicating with it are provided at the rear end. The filling hole and the oil injection hole are separated by 180 degrees. The corners are provided for filling, ejecting the steel balls or injecting butter to lubricate the steel balls and prevent rust. The plug-in connector is inserted from the hole at the rear end of the threaded hole, and its front edge is cut to form a conical contact surface, which is suitable for sticking to the inner surface of the tapered socket at the front end of the threaded hole. Make it move around the center of the piercing hole.

該專利前案係於該裝填孔內設入有一埋頭帽塞，藉以取代習知封閉鋼珠的封閉作用，以避免造成該等鋼珠掉出。惟如此構造，同樣會有裝填鋼珠C耗費作業時間、增加鋼珠製造成本，以及接觸面積小，容易造成固定頭及插接頭鬆脫之缺點存在。The previous patent application is to install a countersunk cap in the filling hole to replace the sealing effect of the conventional closed steel balls to prevent the steel balls from falling out. However, with such a structure, there are also disadvantages such as time-consuming operation of filling the steel ball C, increased manufacturing cost of the steel ball, and small contact area, which easily causes the fixed head and the plug connector to loosen.

又有中華民國98年9月1日所公告之新型第M364153號「活動管接頭」專利案，其係揭露：包括有一套管、一第一接頭及一第二接頭，其係於第二接頭之內環垣設置一環凹槽，而環凹槽內再置入複數圓珠，並於第二接頭外部設有一凸垣，凸垣具有一第一壁面，以第一壁面貼抵於環凹槽之複數圓珠，使第二接頭得以相對套筒而旋轉；藉之，結合後之第二接頭可360度旋轉，使組接於第一接頭及第二接頭之管體不會相互牽動，而致造成扭曲、捲繞之情事發生，以確保管體內部之通暢。There is also a new type M364153 "movable pipe joint" patent case announced by the Republic of China on September 1, 1998, which discloses: including a sleeve, a first joint and a second joint, which are attached to the second joint The inner ring wall is provided with a ring groove, and a plurality of balls are placed in the ring groove, and a protrusion is provided outside the second joint. The protrusion has a first wall surface, and the first wall surface abuts against the ring groove The plurality of balls enables the second joint to rotate relative to the sleeve; through this, the combined second joint can rotate 360 degrees, so that the pipes connected to the first joint and the second joint will not affect each other, and Causes the occurrence of distortion and winding to ensure the smoothness of the inside of the tube.

該專利前案需係先將複數圓珠整齊環列佈置於環凹槽內，再將結合後之第一接頭及第二接頭，以第一接頭之外螺紋螺合於套管之內螺紋，藉以結合套管、第一接頭及第二接頭。惟其雖然可以避免發生套管、第一接頭及第二接頭脫離的缺點，但同樣會有排列鋼珠耗費作業時間及增加製造鋼珠成本之缺點存在，因此在使用上仍不盡理想。The previous patent application requires that a plurality of balls are arranged neatly in the ring groove, and then the first joint and the second joint after the combination are screwed to the inner thread of the casing with the outer thread of the first joint. In order to combine the sleeve, the first joint and the second joint. However, although the shortcomings of detachment of the casing, the first joint and the second joint can be avoided, there are also the shortcomings of arranging the steel balls to consume time and increase the cost of manufacturing the steel balls, so the use is still not ideal.

本創作係為解決習知的活動管接頭構造具有上述缺點。故本創作提供一種活動管接頭，係設有一第一接頭，其一端係凹設有一接合孔，該接合孔的內壁係設有一第一環凹槽；一第二接頭，係與該第一接頭互相結合，該第二接頭的一端係設有一接合端，該接合端上設有一第二環凹槽，該第二環凹槽上套設有一C型扣，該C型扣係彈性卡抵於該第一環凹槽及該第二環凹槽之間，使該第一接頭及該第二接頭不會脫離，而能保持相對旋轉。This creation is to solve the above-mentioned shortcomings of the conventional movable pipe joint structure.
