Description
本創作係關於一種換向式兩用氣嘴接頭，尤指一種可適用於對美、法兩種氣嘴形式的車輛輪胎以進行充氣的氣嘴接頭。 The present invention relates to a reversing dual-purpose nozzle joint, and more particularly to a nozzle joint suitable for inflating vehicle tires in the form of two nozzles of the United States and France.
以自行車產業為例，光是針對不同的輪胎形式就有多種氣嘴規格，常見包括法式氣嘴(Presta valve)、美式氣嘴(Schrader valve)、及英式氣嘴(Dunlop valve)等。然而，由於多種氣嘴形式常常會造成使用者困擾，因為必須針對不同的氣嘴形式更換接頭。 Take the bicycle industry as an example. There are a variety of nozzle specifications for different tire types, including the French valve, the Schrader valve, and the Dunlop valve. However, due to the variety of nozzle forms, the user is often troubled because the joints must be replaced for different nozzle forms.
目前市面上已有多種氣嘴接頭，其可通用於美式和法式氣嘴，例如一種雙頭接頭，其一端可連接美式氣嘴，另一端可連接法式氣嘴。不過，因為此一氣嘴接頭與充氣管採同軸連接，可參考美國專利第US8960214(B2)號，即當欲連接於美式氣嘴時，雙頭接頭之另一端(用於連接法式氣嘴之端部)則必須同軸地連接到充氣管路，故操作上有相當多的限制，有可能會因為輪幅的形式或大小導致無法連接，也容易造成氣嘴或閥桿彎曲變形。此外，此一氣嘴接頭也不符合人體工學，使用者在操作上相當不便。 There are a variety of air nozzle joints available on the market, which can be used for both American and French air nozzles, such as a double-headed joint, one end of which can be connected to the American air nozzle, and the other end can be connected to the French air nozzle. However, since the gas nozzle joint is coaxially connected with the gas tube, reference is made to US Pat. No. 8,906,214 (B2), that is, when the mouthpiece is to be connected to the US air nozzle, the other end of the double-head joint (for connecting the end of the French nozzle) The part must be coaxially connected to the inflation line, so there are considerable restrictions on the operation. It may be impossible to connect due to the form or size of the spoke, and it is easy to cause the nozzle or the stem to bend and deform. In addition, the one nozzle joint is also ergonomic and the user is quite inconvenient to operate.
由此可知，一種操作方便、且符合人體工學，又可適用於至少兩種以上氣嘴規格之氣嘴接頭，實為產業界及一般消費者之迫切需求。 It can be seen that an air nozzle joint which is convenient in operation, ergonomically applicable, and applicable to at least two types of nozzle specifications is an urgent need of the industry and general consumers.

另外，如圖4B中所呈現者係當本實施例之換向式兩用氣嘴連接到美式氣嘴S時之狀態，即以雙向接頭2之美式接頭端21的第一內螺紋211螺接到美式氣嘴S之外螺紋Ss。此時，如圖中所示，美式氣嘴S之美式閥Sv已被內頂件213頂開。亦即，雙向接頭2之美式接頭端21連接到美式氣嘴S後，美式閥Sv即被打開，充氣氣流同樣可自氣壓源流經輸氣道43、中央通氣道31以及貫穿通道23而進入美式氣嘴S；此外，因美式閥Sv隨時處於被開啟之狀態，故美式氣嘴S的氣壓亦可被調節、洩壓，詳如後段所述。 In addition, as shown in FIG. 4B, when the reversing air nozzle of the present embodiment is connected to the American air nozzle S, the first internal thread 211 of the female joint end 21 of the bidirectional joint 2 is screwed. Thread Ss outside the American nozzle S. At this time, as shown in the figure, the American valve Sv of the American air nozzle S has been opened by the inner top member 213. That is, after the American joint end 21 of the two-way joint 2 is connected to the American air nozzle S, the American valve Sv is opened, and the inflated air flow can also flow from the air pressure source through the air passage 43, the central air passage 31 and the through passage 23 to enter the American gas. The mouth S; in addition, because the American valve Sv is in the state of being opened at any time, the air pressure of the American nozzle S can also be adjusted and released, as described in the following paragraph.
請一併參閱圖2和圖5，圖5係本創作一較佳實施例之洩壓機構之剖面圖。本實施例之連接座4更包括一洩壓機構44，其係用於排出輸氣道43內的氣體。進一步說明之，本實施例之洩壓機構44包括一按鈕441、一帽蓋442、一彈簧443及一O型環444，而連接座4開設有一貫穿孔45，該貫穿孔45係與輸氣道43構成連通。另外，帽蓋442組設於貫穿孔45之一端，按鈕441組設於貫穿孔45之另一端並局部地自貫穿孔45凸伸出，彈簧443係位於帽蓋442與按鈕441之間，O型環444則套設於按鈕441上並位於按鈕441與貫穿孔45之內壁間。 Please refer to FIG. 2 and FIG. 5 together. FIG. 5 is a cross-sectional view of the pressure relief mechanism of a preferred embodiment of the present invention. The connector 4 of the present embodiment further includes a pressure relief mechanism 44 for discharging the gas in the air passage 43. Further, the pressure relief mechanism 44 of the present embodiment includes a button 441, a cap 442, a spring 443 and an O-ring 444, and the connecting seat 4 is provided with a consistent through hole 45, which is connected to the gas. The track 43 constitutes a communication. In addition, the cap 442 is disposed at one end of the through hole 45, and the button 441 is disposed at the other end of the through hole 45 and partially protrudes from the through hole 45, and the spring 443 is located between the cap 442 and the button 441, The ring 444 is sleeved on the button 441 and located between the button 441 and the inner wall of the through hole 45.
據此，當按壓按鈕441時，按鈕441與貫穿孔45之內壁間形成空隙，而輸氣道43內的氣體得以自該空隙散逸，故可進行洩壓。更具體的說，當雙向接頭2之美式接頭端21連接到美式氣嘴S時，因美式閥Sv已被內頂件213頂開，故持續處於被開啟之狀態，此時若按壓按鈕441時，美式氣嘴S內的氣體將透過按鈕441與貫穿孔45之內壁間所形成形成空隙流出，即可對美式氣嘴S進行洩壓。 Accordingly, when the button 441 is pressed, a gap is formed between the button 441 and the inner wall of the through hole 45, and the gas in the air passage 43 is dissipated from the gap, so that the pressure can be released. More specifically, when the American joint end 21 of the two-way joint 2 is connected to the American air nozzle S, since the American valve Sv has been opened by the inner top member 213, it is continuously opened, and when the button 441 is pressed The gas in the American nozzle S will flow out through the gap formed between the button 441 and the inner wall of the through hole 45, so that the American nozzle S can be released.
另一方面，本創作之洩壓機構44除了當連接至美式氣嘴S而可進行洩壓外，當連接至法式氣嘴P時，亦可避免法式氣嘴P的氣嘴閥芯(valve cores)Vc鬆脫。進一步說明，請一併參閱圖4A，市面上有些法式氣嘴P的氣嘴閥芯Vc是採用螺轉固定的，在氣嘴內的氣壓未卸除的情況下，因為氣嘴內部係處高壓狀態，而密封件(即O型環)24將受壓迫而緊密連接氣嘴閥芯Vc，故若要使接頭與氣嘴脫離而轉動旋轉軸套3或雙向接頭2時，有可能會連帶氣嘴閥芯Vc一同被旋轉，而致使氣嘴閥芯Vc鬆脫。然而，此時如果按壓按鈕441，可卸除氣嘴(氣管、打氣筒)內的壓力，密封件24則不在受高氣壓之壓迫，當轉動旋轉軸套3或雙向接頭2時，氣嘴閥芯Vc不會隨之旋轉，故可避免氣嘴閥芯Vc鬆脫。 On the other hand, the pressure relief mechanism 44 of the present invention can prevent the valve core of the French air nozzle P when connected to the French air nozzle P, except that it can be depressurized when connected to the American air nozzle S. ) Vc is loose. For further explanation, please refer to FIG. 4A together, the valve core Vc of some French air nozzles P is fixed by screw rotation, and the air pressure in the air nozzle is not removed, because the internal pressure of the air nozzle is high. State, and the seal (ie, O-ring) 24 will be pressed and tightly connected to the nozzle spool Vc. Therefore, if the joint is to be disengaged from the nozzle and the rotary sleeve 3 or the two-way joint 2 is rotated, there may be a gas. The nozzle spool Vc is rotated together to cause the nozzle spool Vc to be released. However, if the button 441 is pressed at this time, the pressure in the air nozzle (air pipe, air pump) can be removed, and the sealing member 24 is not pressed by the high air pressure. When the rotating sleeve 3 or the two-way joint 2 is rotated, the valve is rotated. The core Vc does not rotate with it, so that the nozzle core Vc can be prevented from coming loose.
