Description
本創作係與氣嘴接頭有關,更詳而言之係指一種短頭型美法氣嘴通用接頭。 This creation is related to the gas nozzle joint, and more specifically refers to a short-headed US-style gas nozzle universal joint.
按,自行車之輪胎氣嘴型式眾多,主要分為美式氣嘴與法式氣嘴二種。 According to the bicycle tires, there are many types of air nozzles, which are mainly divided into American air nozzles and French air nozzles.
針對不同型式之氣嘴,習知之充氣接頭無法通用,因此在使用時必須進行更換,而有更換上之不便。目前已有眾多業者研發出可通用美式氣嘴與法式氣嘴之充氣接頭,其主要係在內部設計可活動之頂針,以在頂針被內推時能對法式氣嘴進行充氣,而在頂針被外推時則能對美式氣嘴進行充氣。 For different types of nozzles, the conventional inflation joints cannot be used universally, so they must be replaced when used, and there is inconvenience in replacement. At present, many manufacturers have developed inflatable joints for universal American and French air nozzles. The main purpose is to design a movable ejector inside to inflate the French air nozzle when the ejector pin is pushed in, while the ejector pin is When extrapolated, the American nozzle can be inflated.
然,如我國專利公告第423612號所揭,其主要係在一頭部內設置一凸輪座、一頂掣體及一與該頂掣體連結之頂針,該凸輪座具有一長外徑及一短外徑,當轉動該凸輪座,而由該長外徑抵住該頂掣體時,會將該頂針往外推,以對美式氣嘴進行充氣,或轉動該凸輪座,而由該短外徑抵住該頂掣體時,該頂針能往內縮,而能對法式氣嘴進行充氣。但此種設計由於該頂掣體與該頂針皆在該凸輪座之外活動(即該頂掣體與該頂針係位在凸輪座之旋轉軸心外),因此頭部在設計上便必須具備足夠之長度,以容納該頂掣體與該頂針本身之長度再加上活動之距離,導致頭部會有過長之問題,進而使得在攜帶上及使用上皆相當之不便。 However, as disclosed in Chinese Patent Publication No. 423612, it is mainly provided with a cam seat, a top body and a thimble coupled to the top body in a head portion, the cam seat having a long outer diameter and a a short outer diameter, when the cam seat is rotated, and the long outer diameter is pressed against the top body, the thimble is pushed outward to inflate the American air nozzle, or rotate the cam seat, and the short When the diameter is against the top body, the thimble can be retracted and the French nozzle can be inflated. However, in this design, since the top body and the ejector are movable outside the cam seat (ie, the top body and the thimble are positioned outside the rotation axis of the cam seat), the head must be designed. Sufficient length to accommodate the length of the top body and the thimble itself plus the distance of the movement, resulting in a problem of excessive length of the head, which makes it relatively inconvenient to carry and use.
有鑑於此,為改善先前技術中,習知美法氣嘴通用之接頭有著頭部過長、導致攜帶上及使用上之不便等問題;緣此,本創作乃提供一種短頭型美法氣嘴通用接頭,其主要包含有:一頭部,該頭部一端往內延伸有一容室,該頭部一側往內延伸有一與該容室連通之穿孔;一轉柱,該轉柱係置於該頭部之容室內,可受外力作用進行原地軸轉,該轉柱之內部具有一中空腔室,該轉柱之外周面上徑向開設凹陷有一開口,該開口連通該中空腔室,轉柱於鄰近該開口一端上具有一壓抵部,該轉柱一端具有一導氣孔,該導氣孔連通該中空腔室,該轉柱可受外力作用於一無作用位置至一作用位置間轉動;一壓注件,係自該頭部之穿孔穿入位於該轉柱之中空腔室內,該壓注件一端往內延伸有一容置孔,該壓注件外側具有一連通該容置孔之作用孔;一壓迫環,具彈性,係置於該頭部之穿孔內;一頂針單元,係置於該壓注件之容置孔內,可受外力作用於一美式位置至一法式位置間進行往復之位移;藉以達到有效縮減體積,以增進攜帶上及使用上之方便性。 In view of this, in order to improve the prior art, the conventional joint of the US-style gas nozzle has a problem that the head is too long, causing inconvenience in carrying and use; therefore, the creation provides a short-headed American-style nozzle. The universal joint comprises: a head having a chamber extending inwardly from one end of the head; a side of the head extending inwardly with a perforation communicating with the chamber; a rotating column, the rotating column is placed The inside of the head chamber can be rotated by the external force, and the inside of the rotating column has a hollow chamber. The outer surface of the rotating column is radially opened with an opening, and the opening communicates with the hollow chamber. The column has a pressing portion at one end adjacent to the opening, the rotating column has an air guiding hole at one end thereof, and the air guiding hole communicates with the hollow chamber, and the rotating column can be rotated by an external force to an inactive position to an active position; An injection part is inserted into the cavity of the rotating column from the perforation of the head, and a receiving hole extends from one end of the pressing piece, and the outside of the pressing part has a function of connecting the receiving hole. Hole; an compression ring, elastic, In the perforation of the head; a thimble unit is placed in the receiving hole of the pressure injection member, and can be displaced by an external force between an American position and a French position; thereby achieving effective reduction of the volume, Improve the convenience of carrying and using.

是以,上述即為本創作第一較佳實施例所提供之一種短頭型 美法氣嘴通用接頭100之各部構件及其組裝方式的介紹,接著再將其使用特點說明如下:當欲由本創作對一美式氣嘴91進行充氣時,請參閱第三圖至第六圖,首先,藉由轉動該充氣筒60之筒體61而將該轉柱20旋轉至無作用位置,使該頂針51受到該頂針彈簧52之彈力所推移而被外推至美式位置處(如第四圖所示),再將該美式氣嘴91自該頭部10之穿孔112穿入,並穿經該壓迫環40而與該頂針51抵接(如第四圖所示)。接著,再藉由轉動該充氣筒60之筒體61而將該轉柱20旋轉至作用位置,使該轉柱20在由無作用位置往作用位置轉動時(如第五圖所示),該轉柱20之壓抵部231之擋邊231會穿入於該壓注件30之作用孔32內,並擋抵在該頂針51之端緣上(如第六圖所示),以防止該頂針21內縮(即限制該頂針位於美式位置),再由該壓邊231對該壓注件30產生推移,使該壓注件30連動該壓迫環40,而使該壓迫環40變形束緊於該美式氣嘴91上,以利對該美式氣嘴91進行充氣。 Therefore, the above is a short head type provided by the first preferred embodiment of the present invention. The introduction of the various components of the US-style gas nozzle universal joint 100 and the assembly method thereof, and then the characteristics of its use are described as follows: When inflating an American air nozzle 91 by the present creation, please refer to the third to sixth figures, First, the rotating column 20 is rotated to the inactive position by rotating the cylinder 61 of the inflating cylinder 60, so that the ejector pin 51 is pushed by the elastic force of the ejector pin 52 to be pushed to the American position (such as the fourth As shown, the American air nozzle 91 is inserted through the through hole 112 of the head 10 and passes through the compression ring 40 to abut the thimble 51 (as shown in the fourth figure). Then, the rotating column 20 is rotated to the active position by rotating the cylinder 61 of the inflatable cylinder 60, so that the rotating column 20 is rotated from the inactive position to the active position (as shown in FIG. 5). The rib 231 of the pressing portion 231 of the rotating column 20 penetrates into the working hole 32 of the pressing member 30 and is blocked against the end edge of the ejector pin 51 (as shown in FIG. 6) to prevent the The thimble 21 is retracted (ie, the thimble is restricted to be in the U.S. position), and the nip 231 is displaced by the hem 231, so that the nip 30 interlocks the compression ring 40, and the compression ring 40 is deformed and tightened. The American air nozzle 91 is inflated on the American air nozzle 91.
當欲由本創作對一法式氣嘴92進行充氣時,請參閱第七圖至第九圖,首先,藉由轉動該充氣筒60之筒體61而將該轉柱20旋轉至無作用位置,再將該法式氣嘴91自該頭部10之穿孔112穿入,並穿經該壓迫環40而將該頂針51內推至法式位置(如第七圖所示)。接著,再藉由轉動該充氣筒60之筒體61而將該轉柱20旋轉至作用位置,使該轉柱20在由無作用位置往作用位置轉動時(如第八圖所示),該轉柱20之擋邊231會穿入於該壓注件30之作用孔32內,而使該法式氣嘴92位於該二擋邊231之間(如第九圖所示),再由該壓邊23 1對該壓注件30產生推移,使該壓注件30連動該壓迫環40,而使該壓迫環40變形束緊於該法式氣嘴91上,以利對該法式氣嘴91進行充氣。 When the French air nozzle 92 is to be inflated by the present invention, please refer to the seventh to ninth drawings. First, the rotating column 20 is rotated to the inactive position by rotating the cylinder 61 of the inflatable cylinder 60, and then The French air nozzle 91 is inserted through the through hole 112 of the head 10 and passes through the compression ring 40 to push the ejector pin 51 to the French position (as shown in the seventh figure). Then, by rotating the cylinder 61 of the inflatable cylinder 60, the rotating column 20 is rotated to the active position, so that the rotating column 20 is rotated from the inactive position to the active position (as shown in FIG. 8). The rib 231 of the rotating column 20 penetrates into the working hole 32 of the pressure injecting member 30, so that the French air nozzle 92 is located between the two ribs 231 (as shown in FIG. 9), and then the pressure Side 23 1 The pressing member 30 is displaced, and the pressing member 30 is interlocked with the pressing ring 40, so that the pressing ring 40 is deformed and tightened to the French air nozzle 91 to inflate the French air nozzle 91.
是以,由於本創作之頂針可在活動至該轉柱之中空腔室內,因此可大幅減縮該頭部供該頂針活動之長度,進而有效地減少整體之體積,以利攜帶及使用上之方便性。 Therefore, since the thimble of the present creation can be moved into the cavity of the rotating column, the length of the thimble can be greatly reduced, thereby effectively reducing the overall volume, so as to facilitate carrying and use. Sex.
