捌、創作說明： 一、 創作所屬之技術領域： 本創作係有關於一種可撓管之隨動止漏結構，特別是 指利用一設於外套管内之可動擋環，配合止漏膠圈，使管 線能容許伸縮及旋轉之偏位動作，有效減少可撓管漏水之 情況發生，且能增加内套管更大的旋轉偏擺角度。 二、 先前技術： 目前市面上各種流體輸送裝置，為避免輸送管因地震 等因素而損壞，故會使用可撓管來吸收震動，並使輸送管 的裝設路線有更大的彈性。而有時單一輸送管無法直接到 達所需之位置，此時則需使用一專用接頭來連接兩輸送 管，達到延長之目的；該專用接頭除了連接之功用外，還 需有防止、;戈漏之功用。 如圖5所示，習用之可撓管包括：一外套管，其 兩端開口内設有擋環91;及兩内套管92，穿設於外套管9〇 兩端之開口中；及兩膠圈槽93，設於外套管9〇兩端；及 兩止漏膠圈94，設於膠圈槽93内。其中内套管92係用以 與兩端相鄰之管線銜接。 如圖6〜7所示，當兩端相鄰之管線受外力作用時， 内套官92會產生伸縮或旋轉之動作；此時，外套管卯上 之擋環91為不制限内套管92之動作，必須將擋環μ長 度縮短，使可撓管能發揮預期之功能。 曰 ^ 如圖7所示，因擋環91的長度縮短，當内套管犯往 外套管90内移動時，會帶動止漏膠圈94變形與位移，降 低止漏膠圈94的功用，使可撓管發生洩漏。 綜上所述，習用之可撓管因外套管上之撞環犯的 長度縮短，而降低了止漏膠圈94之密封功能，造成流體 茂漏；有鑑於此，本創作人乃針對習用可撓管之止漏膠圈， 苦思細索，積極研究，再加上不斷的實驗改良，終於發展 出本創作。 三、 創作内容： 本創作之目的在提供—種不會_套管的伸縮及旋轉 而使膠圈產生位移與變形之可撓管之隨動止漏結構。其構 造上係設有-外套管’至少具—開σ，於開口處設有賴 槽與導槽；及内套管’套設在外套管之開σ巾；及膠圈， 設於膠圈槽中；其中外套管之導槽内設有—可動擋環；當 内套管旋轉獅時，可域環可於導槽崎内套管之動作 而滑動’ _賴卵之動作，仙外套管套合處完全密 合而具有止漏效果。 本創作之另一目的在提供一種内套管可容許更大之旋 ，偏擺角度之可撓管之隨動止漏結構。其構造上係於外套 &上。又#槽’使该導槽内設一可動撞環；該可動撞環能 依内套管的動作在中滑動，仙套管有更大之旋轉偏擺角 度。 本創作為達成上述及其他目的，所採用之技術手段、 元件及功效，茲取一較佳實施例，詳細說明如下。 四、 實施方式： 本創作係提供-種可撓管之隨動止漏結構，其中包括： M241560 -外套管1G ’設有至少—個之開σ，錄開口處 槽11與導槽12;及内套管20，穿設於外套管1〇之開口内 及踢圈30 ’設於外套管1〇之膠圈槽^内 導 槽内設-可動擔環21，該可動擔環&可隨内寺套徵管= 2二導槽12内滑動’使膠圈3〇不會因變形而失去防 漏的功能。以下將詳予說明。 防 如圖1所示’本創作包括·一外套管，至一 =穿設有_抑與導槽12;及内套管别， ^ g ι〇之開口中，另一端可連接其它管線. 膠圈槽11中，·其特徵在於··外套管10之 2m動擔環21，該可動擋環21可於導㈣内 ㈣^之動作而滑動，限制膠圈30之動作，可有效 避免膠圈30因内套替 移位之現象。 的伽及旋轉偏擺喊生變形與 如圖2〜4所示，合允太总〇Λ 作用時，内套管20會產田之管線受到外力 動擋環21可以配合内套管m轉偏擺的動作，此時可 12中_，㈣_套20的動作’在外套管11之導槽 會因内套^〇的二3〇限制在膠圈槽11内，使勝圈30不 會因，套官2G的作用而發生變形與位移。 二 1敝=，〗用可動擋環21限制了賴30的 有效減少可撓管域之情形_^2G陳轉躺或伸縮’ 的旋轉偏㈣導槽環21可配合内套管 動作，可增加内套管2_㈣度不會限制内套官20的 M241560 以上為本案所舉實施例，僅為便於說明而設，當不能 以此限制本案之意義，即申請專利範圍所列之各種變換設 計，均應包含在本案之專利範圍中，敬請鈞局暨貴審查 委員能早日賜予本案專利，實感德便。 五、圖式簡單說明： 圖1係本創作之剖面示意圖。 圖2係本創作受外力時之剖面示意圖。 圖3係本創作取圖2之a處之簡略剖面示意圖。 圖4係本創作取圖2之b處之簡略剖面示意圖。 圖5係習用可撓管之剖面示意圖。 圖6係習用可撓管受外力時之剖面示意圖。 圖7係習用可撓管取圖6之c處，止漏膠圈變形時之 簡略剖面示意圖。 圖號說明： 10…·· ....外套管 11…·, .....膠圈槽 12…·. ....導槽 20…·, .....内套管 21…·· ....可動擋環 30…·, .....膠圈 90…·. ....外套管 91…· .....擋環 92…·, 内套管 93…· .....膠圈槽 94…·. .....止漏膠圈创作, creation instructions: 1. The technical field of creation: This creation is about a follow-up leak-proof structure of a flexible tube, especially a movable stop ring provided in the outer sleeve, and a leak-proof rubber ring, so that The pipeline can allow the deflection action of telescoping and rotation, effectively reduce the occurrence of water leakage in the flexible pipe, and can increase the larger rotation deflection angle of the inner casing. 2. Prior technology: At present, various fluid conveying devices on the market, in order to avoid the damage of the conveying pipe due to factors such as earthquakes, will use flexible pipes to absorb vibration and make the installation route of the conveying pipe more flexible. And sometimes a single conveying pipe cannot reach the required position directly. At this time, a special joint needs to be used to connect the two conveying pipes to achieve the purpose of extension. In addition to the connection function, the special joint needs to be prevented and leaked. Function. As shown in FIG. 5, the conventional flexible tube includes: an outer tube, which is provided with a retaining ring 91 in the opening at both ends; and two inner sleeves 92 which are passed through the openings at the two ends of the outer tube 90; and two The apron groove 93 is provided at both ends of the outer sleeve 90; and two leak-proof apron 94 are provided in the apron groove 93. The inner sleeve 92 is used for connecting with the adjacent pipelines at both ends. As shown in Figs. 6-7, when the adjacent pipelines at both ends are subjected to external force, the inner sleeve 92 will produce a telescoping or rotating action; at this time, the retaining ring 91 on the outer sleeve 为 is an unlimited inner sleeve 92 During the operation, the length of the retaining ring μ must be shortened so that the flexible tube can perform the expected function. As shown in FIG. 7, because the length of the retaining ring 91 is shortened, when the inner sleeve moves into the outer sleeve 90, it will drive the deformation and displacement of the leak-proof rubber ring 94, reducing the function of the leak-proof rubber ring 94, so that Leak in flexible tube. In summary, the flexible tube used has shortened the length of the collision ring on the outer tube, which reduced the sealing function of the leak-proof rubber ring 94, causing fluid leakage. In view of this, the author is The leak-proof rubber ring of the flexible tube, carefully studied, and actively researched, combined with continuous experimental improvement, finally developed this creation. Third, the content of the creation: The purpose of this creation is to provide a kind of follow-up leak-proof structure of the flexible tube that will not cause the expansion and rotation of the casing and cause the rubber ring to move and deform. The structure is provided with-an outer sleeve 'at least with-opening σ, and a grooving groove and a guide groove are provided at the opening; and an inner sleeve' open σ towel is sleeved on the outer sleeve; and a rubber ring is provided in the rubber ring groove. In the guide groove of the outer sleeve, a movable retaining ring is provided. When the inner sleeve rotates the lion, the field ring can slide in the movement of the inner sleeve of the guide groove. The joint is completely tight and has a leak-proof effect. Another purpose of this creation is to provide a follow-up leak-proof structure of a flexible tube with an inner sleeve that allows greater rotation and a deflection angle. It is structurally tied to the jacket &. Moreover, the #groove 'is provided with a movable striker ring in the guide groove; the movable striker ring can slide in the middle according to the action of the inner sleeve, and the fairy sleeve has a larger rotation deflection angle. In order to achieve the above and other objectives, the technical means, components and effects used in this creation are a preferred embodiment, which is described in detail below. Fourth, the implementation mode: This creative system provides-a flexible tube with a follow-up leak-proof structure, including: M241560-outer tube 1G 'with at least one opening σ, record the opening slot 11 and guide slot 12; and The inner sleeve 20 is passed through the opening of the outer sleeve 10 and the kick ring 30 'The rubber ring groove provided on the outer sleeve 10 is provided inside the inner guide groove-a movable stretcher ring 21, which Inner temple sleeve collection tube = 2 Sliding in the second guide groove 12 so that the rubber ring 30 will not lose its leak-proof function due to deformation. This will be explained in detail below. Prevent as shown in Figure 1 'This creation includes a jacket tube, to one = wear _ 抑 and guide groove 12; and the inner sleeve, ^ g ι〇 opening, the other end can be connected to other pipelines. Glue The ring groove 11 is characterized by a 2m movable stretch ring 21 of the outer sleeve 10, which can slide in the movement of the guide ring ^, restrict the movement of the aprons 30, and effectively avoid the aprons. 30 due to the phenomenon of inner sleeve displacement. As shown in Figures 2 to 4, when the Gyro rotation and deflection swings, as shown in Fig. 2 ~ 4, the inner casing 20 will produce the pipeline under the action of the external force. The retaining ring 21 can cooperate with the inner casing m to deviate. At this time, the action of the swing can be 12 in the _, __ set of 20 'in the guide groove of the outer sleeve 11 will be limited to the aprons groove 11 due to the inner sleeve ^ 2 30, so that the winning circle 30 will not be caused by Deformation and displacement occur due to the role of arrogant 2G. Two 1 敝 =,〗 The use of the movable retaining ring 21 limits the effective situation of Lai 30 to reduce the flexible pipe area _ ^ 2G Chen Zhuan lie or extend the 'rotating partial guide groove ring 21 can cooperate with the inner sleeve action, can increase The inner sleeve 2_㈣ will not restrict the M241560 of the inner sleeve officer 20 and above. This is an example for the purpose of this case. It is provided for ease of illustration. When the meaning of this case cannot be limited, that is, the various transformation designs listed in the scope of the patent application, all It should be included in the scope of patents in this case, and I would like to ask the Bureau of Examination and Your Examination Committee to grant the patent in this case at an early date.
