Description
本創作係有關一種接頭之結構,尤指一種可防止膠環脫離本體之接頭結構。
This creation relates to the structure of a joint, especially a joint structure that prevents the rubber ring from coming off the body.
如第6圖所示,為習用接頭之結構,包括一本體91、一螺帽92、一膠環93及一內芯94,該螺帽92罩設在本體91之頭部911,膠環93設於該頭部911中,內芯94鎖設在該頭部911內。
此習用接頭之結構,設於冷媒量測器具,用於銜接冷媒管之接頭,藉此測量冷媒之高壓及低壓。其中,係以本體91與冷媒管之接頭抵接,並以螺帽92鎖緊於冷媒管之接頭,而使冷媒量測器具能測得冷媒管內之壓力。
然而,當壓力形成於該本體91之頭部911時,由於冷媒中含有油分,故冷媒會隨高壓而滲入該膠環93外周,而造成膠環93於頭部911內被潤滑而容易鬆脫。故實際使用時,原本鎖在冷媒管之接頭之接頭,常在拆離冷媒管之接頭時,膠環93即掉出該頭部911外,若操作人員未發現膠環93掉落而即時裝回,接頭在重新安裝新的膠環93前便無法再繼續使用。
因此,如何解決上述習用接頭之結構之問題者,即為本創作之主要重點所在。
As shown in FIG. 6, the structure of the conventional joint includes a body 91, a nut 92, a rubber ring 93 and an inner core 94. The nut 92 is disposed on the head 911 of the body 91, and the rubber ring 93 Provided in the head 911, the inner core 94 is locked in the head 911.
The structure of the conventional joint is provided in a refrigerant measuring device for connecting the joint of the refrigerant pipe, thereby measuring the high pressure and low pressure of the refrigerant. Wherein, the body 91 is abutted against the joint of the refrigerant tube, and the nut 92 is locked to the joint of the refrigerant tube, so that the refrigerant measuring instrument can measure the pressure in the refrigerant tube.
However, when the pressure is formed on the head 911 of the body 91, since the refrigerant contains oil, the refrigerant penetrates into the outer periphery of the rubber ring 93 with the high pressure, and the rubber ring 93 is lubricated in the head 911 to be easily released. . Therefore, in actual use, the joint originally locked in the joint of the refrigerant pipe, often when the joint of the refrigerant pipe is detached, the rubber ring 93 falls out of the head 911, and if the operator does not find the rubber ring 93 falling, it is installed immediately. Back, the connector can no longer be used until the new rubber ring 93 is reinstalled.
Therefore, how to solve the problem of the structure of the above-mentioned conventional joints is the main focus of the creation.
本創作之主要目的,在於解決上述的問題而提供一種接頭之結構,藉由內芯在本體之頭部中迫緊膠環於容室之底部,而使膠環能確實被固定在容室內,確保接頭能繼續使用。

請參閱第1圖至第5圖,圖中所示者為本創作所選用之實施例結構,此僅供說明之用,在專利申請上並不受此種結構之限制。
本實施例提供一種接頭之結構,其係如第1至2圖所示,包括一本體1、一螺帽2、一膠環3及一內芯4,其中:
如第2至3圖所示,該本體1一端具有一頭部11,此頭部11中具有一容室12,且頭部11於該容室12的底部具有一內螺紋部13。
如第2至3圖所示,該螺帽2罩設於該本體1之頭部11,螺帽2內具有一於所罩設之頭部11外之螺牙段21。
如第2至4圖所示,該膠環3具有可撓之彈性,係設置於該容室12中,且外周31抵接於該頭部11於容室12內之側壁111,具有一穿孔32。
如第2至4圖所示,該內芯4一端具有一外螺紋部41,以此外螺紋部41鎖設於該內螺紋部13,內芯4於外螺紋部41的另一端具有一頂推部42,於外螺紋部41與該頂推部42間具有一連接部43。
如第2至4圖所示,本實施例之穿孔32包含一開口朝該容室12外之大徑孔321,以及一開口朝該容室12內之小徑孔322,該膠環3於其穿孔32內由該大徑孔321與小徑孔322之徑差形成一第一擋緣33。
如第2至4圖所示,本實施例之連接部43包括一鄰近該外螺紋部41之小徑段431伸設於該小徑孔322中,及一鄰近該頂推部42之大徑段432伸設於該大徑孔321中,該連接部43之大徑段432與小徑段431之徑差形成一第二擋緣44,以此第二擋緣44在該外螺紋部41鎖入該內螺紋部13時,抵壓該第一擋緣33而迫緊該膠環3於該容室12之底部。
由上述之說明不難發現本創作之優點,在於當膠環3及內芯4皆設於本體1之頭部11內時,透過該內芯4之連接部43於大徑段432與小徑段431之徑差形成之第二擋緣44抵壓膠環3於其穿孔32內由該大徑孔321與小徑孔322之徑差形成之第一擋緣33,藉此將膠環3迫緊於該容室12之底部。因此在冷媒測量過程中,當壓力形成於該本體1之頭部11時,雖然冷媒中含有油分,惟膠環3被確實迫緊於容室12之底部,故冷媒隨高壓而滲入該膠環3外周的機率能相對降低,且即使冷媒隨高壓而滲入該膠環3外周,亦能藉由內芯4之連接部43的第二擋緣44抵壓於該第一擋緣33而阻擋膠環3於頭部11內被潤滑而鬆脫。
當然,本創作仍存在許多例子,其間僅細節上之變化。請參閱第5圖,其係本創作之第二實施例,其包含一本體1、一螺帽2、一膠環3A及一內芯4A,與第一實施例之主要差異,在於該膠環3A之穿孔32A中具有一斜錐孔321A,此斜錐孔321A之孔徑由朝該容室12外的一端向朝該容室12內的一端漸縮。該連接部43A具有一錐度對應該斜錐孔321A之斜錐部431A,以此斜錐部431A在該外螺紋部41A鎖入該內螺紋部13時抵壓該斜錐孔321A之內壁,同樣可達到與第一實施例迫緊該膠環3A於該容室12之底部之功效。
以上所述實施例之揭示係用以說明本創作,並非用以限制本創作,故舉凡數值之變更或等效元件之置換仍應隸屬本創作之範疇。
由以上詳細說明,可使熟知本項技藝者明瞭本創作的確可達成前述目的,實已符合專利法之規定,爰提出專利申請。
