Description

快速接頭結構 Quick connector structure

本創作有關於一種快速接頭結構，特別是一種方便加工與安裝又具有高密封性及連接可靠性快速接頭結構。 This invention relates to a quick connector structure, especially a quick connector structure that is easy to process and install and has high sealing performance and connection reliability.

按，在目前氣態供氣系統或液體冷卻系統中，通常用管路及接頭連接各單元模組，管路內部有流動的氣或液體存在，各別模組單元在使用和維護時需要經常得進行分斷和接合操作，但在管路斷開操作較為繁瑣之情況下易發生洩漏影響環境及系統安全穩定性，故需要使用具有可快速斷開且單向密封功能的快速斷開連接器(Quick Disconnect Coupler)，俗稱QDC快速接頭。通常快速接頭母頭連接於固定模組，而公頭一端與軟管相連另一端與母頭插接端進行接駁操作，由此實現系統中的管路的導通或斷開。 According to the current gas supply system or liquid cooling system, pipelines and joints are usually used to connect each unit module. There is flowing gas or liquid inside the pipeline, and each module unit needs to be frequently used and maintained during use and maintenance. Carry out disconnecting and joining operations, but when the pipeline disconnection operation is more cumbersome, leakage may easily occur, affecting the environment and system safety and stability. Therefore, it is necessary to use a quick disconnect connector with a quick disconnect and one-way sealing function ( Quick Disconnect Coupler), commonly known as QDC quick connector. Usually the female end of the quick connector is connected to the fixed module, and one end of the male end is connected to the hose and the other end is connected to the plug end of the female end to connect or disconnect the pipelines in the system.

現有的公頭和母頭之連接結構，請參閱第4圖，其包括相插接的單向插頭4及單向插座5，該單向插頭4具有一插頭殼體41、活動閥件42、彈簧43，該插頭殼體41由一前段411及一後段412連接構成，且插頭殼體41一端為插接段413及另一端為公頭連接段414，並於插頭殼體41內設一插頭流體通道可容設該彈簧43，該活動閥芯件42係裝配於該插頭流體通道中對應該插接段413處的開口，並該活動閥件42周面上設有密封圈44。該單向插座5具有一插座殼體51、固定閥件52、彈簧53，該插座殼體51由一前段511及一後段512連接構成，且插座殼體51一端為卡接端513及另一端為公頭連接段514，並於插座殼體51內設有一插座流體通道可容設該彈簧53，該固定閥芯件52係裝配於該插座流體通道中用於可與活動閥件42軸向互抵，且該固定閥芯件52外表面與該插座殼體51內壁之間間隔形成一 環隙，該環隙中設置一可軸向移動的一活動密封體54，並於該固定閥件52外壁面上與插座殼體51內壁上分別設有一密封圈55和密封圈56，用於各自與該活動密封體54徑向密封配合。在該插座殼體51的卡接端513***該插頭殼體41的插接段413內時，利用該插座殼體51內壁的密封圈56與插頭殼體41外壁徑向密封配合，且該插頭殼體41的插接段413可軸向頂推該插座殼體51內的活動密封圈54朝後段512方向位移，並該活動閥件42被該固定閥件52抵頂並一起進入該插頭殼體41的插頭流體通道中，藉此使得插頭4、插座5的各自流體通道導通，實現單向閥的打開。然而，如上這種習知快速接頭組件存在以下問題：1、密封圈56固定在插座殼體51內壁上，因而必需先在插座殼體的管狀內壁上加工形成密封圈固定槽，但是基於管狀口徑大小有限，對於在管狀內壁上凹設固定槽的加工施作難度極大、不易測量固定槽直徑和寬度尺寸，易造成品質無法精準控制缺點，或產生歪斜之虞慮；2、因管狀口徑造成插座殼體51內壁的固定槽較淺，因此使得密封圈僅能淺淺地定位在固定槽內，或者活動密封體54位在固定閥件52與插座殼體51之間預設的該環隙中，故在插頭殼體進行***或拔出過程中，容易刮擦密封圈、密封體或使密封圈、密封體易受剪切力而發生翻轉現象，進而發生密封圈脫出或刮傷受損情況，由此造成失效洩漏的問題；3、現有技術為了減輕插頭殼體***過程帶來的上述問題隱患，通常將密封圈或密封體內徑設置變小，如此一來，係以減小其***頭殼體接合擠壓變形量，雖能減輕上述不良現象發生，但因其干涉變形量減少，其緊迫力也同步變小而使其耐氣液壓力變小，通常在管路內部壓力1.5Mpa以上帶壓操作時，快速接頭發生洩漏率將明顯增大。另一方面，前述減小密封圈的做法相對於固定槽加工時的直徑尺寸容差對應變更小，對於機械加工精度要求必定大幅提高。無疑將大幅降低製品良率提高生產成本。 Please refer to Figure 4 for the existing male and female connection structure, which includes a one-way plug 4 and a one-way socket 5 that are connected to each other. The one-way plug 4 has a plug housing 41, a movable valve 42, Spring 43. The plug housing 41 is composed of a front section 411 and a rear section 412. One end of the plug housing 41 is a plug-in section 413 and the other end is a male connecting section 414. A plug is provided in the plug housing 41. The fluid channel can accommodate the spring 43. The movable valve core member 42 is assembled in the opening corresponding to the plug-in section 413 in the plug fluid channel, and a sealing ring 44 is provided on the peripheral surface of the movable valve member 42. The one-way socket 5 has a socket shell 51, a fixed valve 52, and a spring 53. The socket shell 51 is composed of a front section 511 and a rear section 512, and one end of the socket shell 51 is a snap end 513 and the other end. It is a male connecting section 514, and a socket fluid channel is provided in the socket housing 51 to accommodate the spring 53. The fixed valve core component 52 is assembled in the socket fluid channel to be able to axially communicate with the movable valve component 42. offset each other, and a gap is formed between the outer surface of the fixed valve core member 52 and the inner wall of the socket housing 51 An annular gap is provided with an axially movable movable sealing body 54, and a sealing ring 55 and a sealing ring 56 are respectively provided on the outer wall surface of the fixed valve member 52 and the inner wall of the socket housing 51. Each of them is in radial sealing cooperation with the movable sealing body 54 . When the clamping end 513 of the socket housing 51 is inserted into the plug-in section 413 of the plug housing 41, the sealing ring 56 on the inner wall of the socket housing 51 is used to radially seal with the outer wall of the plug housing 41, and the The insertion section 413 of the plug housing 41 can axially push the movable sealing ring 54 in the socket housing 51 toward the rear section 512, and the movable valve member 42 is pushed against the fixed valve member 52 and enters the plug together. In the plug fluid channel of the housing 41, the respective fluid channels of the plug 4 and the socket 5 are connected, thereby realizing the opening of the one-way valve. However, the above conventional quick connector assembly has the following problems: 1. The sealing ring 56 is fixed on the inner wall of the socket housing 51. Therefore, a sealing ring fixing groove must be formed on the tubular inner wall of the socket housing first. However, based on The size of the tubular diameter is limited, and it is extremely difficult to process the fixing groove recessed on the inner wall of the tubular. It is not easy to measure the diameter and width of the fixing groove, which may easily lead to the disadvantage of inaccurate quality control or the risk of skew; 2. Due to the tubular shape The diameter causes the fixed groove on the inner wall of the socket housing 51 to be shallow, so that the sealing ring can only be positioned shallowly in the fixed groove, or the movable sealing body 54 is positioned between the fixed valve member 52 and the socket housing 51. In this annular gap, during the insertion or extraction process of the plug housing, the sealing ring and sealing body are easily scratched, or the sealing ring and sealing body are susceptible to shearing force and overturning, resulting in the sealing ring coming out or scratches and damage, resulting in failure and leakage problems; 3. In order to alleviate the above-mentioned problems caused by the insertion process of the plug shell in the existing technology, the sealing ring or the inner diameter of the seal is usually set smaller. In this way, the system Reducing the amount of extrusion and deformation caused by the plug shell engagement can alleviate the occurrence of the above-mentioned adverse phenomena. However, due to the reduction of interference deformation, the pressing force also becomes smaller simultaneously, making its resistance to gas and hydraulic pressure smaller, usually inside the pipeline. When operating under pressure above 1.5Mpa, the leakage rate of quick connectors will increase significantly. On the other hand, the aforementioned method of reducing the sealing ring corresponds to a smaller diameter tolerance when processing the fixed groove, and the requirements for machining accuracy must be greatly improved. It will undoubtedly significantly reduce product yield and increase production costs.

該連接管13的上、下兩端分別具有一受接端131及一插接端132並兩者相互貫通。該連接管13具有一第一區段13a及一第二區段13b，並兩者的外管徑並不相同，故在兩者相連接處形成有一第一階部136。 The upper and lower ends of the connecting pipe 13 have a receiving end 131 and a plug-in end 132 respectively, and the two ends penetrate each other. The connecting pipe 13 has a first section 13a and a second section 13b, and the outer diameters of the two sections are different, so a first step 136 is formed at the connection point between the two sections.

該連接管13的第一區段13a的外部管壁13aa設有至少一第一環槽133，該第一環槽133嵌設有一第二密封體134，而位在該連接管13下端的插接端132的末端處向該連接管13的中心方向向內漸縮形成一第一縮口部135並具有一第一貫通孔135a。 The outer wall 13aa of the first section 13a of the connecting pipe 13 is provided with at least a first annular groove 133. The first annular groove 133 is embedded with a second sealing body 134, and the insertion hole at the lower end of the connecting pipe 13 is The end of the connecting end 132 is tapered inward toward the center of the connecting pipe 13 to form a first constriction 135 and has a first through hole 135a.

When the male and female joints are assembled or removed, the shear force generated along the axial direction causes the The sealing ring was turned over or pulled out together, or the sealing ring was scratched or missing. Therefore, in this case, the space where the sealing body was originally installed was (Ring groove), which is conventionally provided on the inner wall surface of the screw hole or round pipe, is changed to be provided on the outer pipe wall at the relative sliding fitting position of the pipe body components. In this way, processing is performed on the outer wall surface of the pipe body, which is relatively smooth. Compared with the conventional method of processing in the hole of the pipe body, it is more convenient and simple, and the precision control is more precise. The sealing ring is set in the ring groove outside the pipe body, and the ring groove provides the sealing ring with Positioning and fixation, and when the male and female joint components are relatively plugged into each other and slide into each other, the sealing rings will not be turned over or pulled out of their original position due to shear force, thus improving the habit.
