Two expansion holes are formed inside a ball head of the rocker, and the narrow ends of the two expansion holes are connected to form a long hole in the center of the ball head. The spindle and the steel ball are arranged inside the joint, and the spindle pushes a part of the steel ball to expose the joint. The pin passes through the long hole of the rocker and the joint, so that the ball head is placed in a circular groove of the joint and can swing relative to each other. The pin is kept at a distance from one end of the long hole, allowing the rocker to move a stroke in a straight line, so that the spindle no longer drives the steel ball to be exposed outside the joint, thereby helping the connecting rod to quickly connect with a spark plug sleeve and be detachable.
Description
本發明關於手工具的領域,尤指一種接桿,適用一個火星塞安裝於一般的車輛,或從該車輛拆卸所述的火星塞。The present invention relates to the field of hand tools, and more particularly to a connecting rod suitable for installing a spark plug on a general vehicle, or removing the spark plug from the vehicle.
以燃料(如汽油、柴油或液化石油氣等)產生動能的車輛,通常具備一顆引擎。通過螺鎖方式,該引擎安裝一個以上的火星塞。一把手工具鎖緊或旋鬆所述的火星塞,故該手工具稱為火星塞套筒板手,抑或是套筒板手。A vehicle that generates kinetic energy using fuel (such as gasoline, diesel or liquefied petroleum gas, etc.) usually has an engine. The engine is equipped with one or more spark plugs by screwing. A hand tool is used to tighten or loosen the spark plug, so the hand tool is called a spark plug socket wrench, or a socket wrench.
中國公告第2618731Y號實用新型專利案,揭露所述火星塞套筒板手為一個T型的結構體,由一根橫手柄結合一根操作桿的一端,該操作桿的另端連到一個套筒,所述套筒專用單一規格的火星塞。不同尺寸的火星塞,必須更換合適的套筒。該套筒與所述操作桿成為一體,一名使用者往往需要準備二把以上的火星塞套筒板手,才能隨時更換合適的手工具,應付火星塞的安裝或拆卸。然而,多把火星塞套筒板手除了增加製作成本以外,還會增加負荷,不利攜帶。China's Utility Model Patent Case No. 2618731Y discloses that the spark plug socket wrench is a T-shaped structure consisting of a horizontal handle combined with one end of an operating rod, the other end of which is connected to a socket, and the socket is dedicated to a single specification of spark plugs. Spark plugs of different sizes must be replaced with appropriate sockets. The socket and the operating rod are integrated, and a user often needs to prepare more than two spark plug socket wrenches to replace the appropriate hand tools at any time to deal with the installation or removal of the spark plug. However, in addition to increasing the manufacturing cost, multiple spark plug socket wrenches will also increase the load and are not easy to carry.
中國授權公告第2707436Y號實用新型專利案,揭露所述的套筒扳手具備一根上樞支軸與一根下樞支軸,該下樞支軸將一個套筒和一個萬向連接桿連在一起,該上樞支軸把所述萬向連接桿及一根手柄連在一起。上、下二樞支軸選用鉚釘來實施,因為鉚釘不利於抽換,所以套筒、萬向連接桿與手柄相連不易更替,存在套筒專用單一規格火星塞的限制條件,仍須準備多把套筒扳手才能應付不同規格火星塞的安裝或拆卸,故製作成本依舊昂貴,而且荷重並未減輕,不利於攜帶。China's utility model patent case No. 2707436Y, published in the China Patent Publication, discloses that the socket wrench has an upper pivot and a lower pivot, the lower pivot connects a socket and a universal connecting rod, and the upper pivot connects the universal connecting rod and a handle. The upper and lower pivots are implemented with rivets, which are not easy to replace, so the socket, universal connecting rod and handle are not easy to replace. There is a limitation that the socket is dedicated to a single specification of spark plugs, and multiple socket wrenches must be prepared to cope with the installation or removal of spark plugs of different specifications. Therefore, the manufacturing cost is still expensive, and the load is not reduced, which is not convenient for carrying.
因此,如何減輕攜帶的負擔,改善製作成本昂貴等弊端,就成為本發明亟待解決的課題。Therefore, how to reduce the burden of carrying and improve the disadvantages of high manufacturing cost has become an urgent problem to be solved in the present invention.
基於火星塞的安裝或拆卸,本案發明人研究新的接桿,主要目的在於:採用組合式結構,除了搖桿連到接頭而能相互擺動以外,讓搖桿兼具快速拆卸的功能,幫助接頭結合所需的火星塞套筒,有效地解決習用技術存在已久的負荷較重、不利攜帶以及製作成本昂貴等弊端。Based on the installation or removal of the spark plug, the inventor of this case studied a new connecting rod, the main purpose of which is to adopt a modular structure. In addition to the rocker being connected to the connector and being able to swing relative to each other, the rocker also has the function of quick removal, helping the connector to combine with the required spark plug socket, effectively solving the long-standing drawbacks of the conventional technology, such as heavy load, inconvenience in carrying, and high manufacturing cost.
為了達成快拆目的,本發明的接桿,包括:一根搖桿、一個接頭、一根銷、一根芯軸與一顆鋼球。該搖桿的一個球頭內部形成二個擴張孔,二該擴張孔的窄端在所述球頭內部中央相向連成一個長孔。該芯軸與該鋼球配置所述接頭的內部,該芯軸推動所述鋼球的局部外露該接頭。該銷穿過所述搖桿的長孔與該接頭,使該球頭置入所述接頭的一個圓槽而能相互擺動。該銷至所述長孔的一端維持一個距離,允許該搖桿依直線運動一個行程,使該芯軸不再驅動所述鋼球露出該接頭外,幫助該接桿快速結合一個火星塞套筒而可拆卸。In order to achieve the purpose of quick release, the connecting rod of the present invention includes: a rocker, a joint, a pin, a spindle and a steel ball. Two expansion holes are formed inside a ball head of the rocker, and the narrow ends of the two expansion holes are connected to form a long hole in the center of the ball head. The spindle and the steel ball are arranged inside the joint, and the spindle pushes a part of the steel ball to expose the joint. The pin passes through the long hole of the rocker and the joint, so that the ball head is placed in a circular groove of the joint and can swing relative to each other. The pin is kept at a distance from one end of the long hole, allowing the rocker to move a stroke in a straight line, so that the spindle no longer drives the steel ball to be exposed outside the joint, thereby helping the connecting rod to quickly connect with a spark plug sleeve and be detachable.

如第1圖所示,本發明一根接桿20的第一實施例,其結合一把手工具10與一個火星塞套筒11。As shown in FIG. 1 , a first embodiment of a connecting
此處所述的手工具10,是指一把扳手。所述扳手的一端有一個頭部15,另端具備一個握持部16。該頭部15安裝一個驅動組件17,所述驅動組件17的一個棘輪(圖未示)能在該頭部15內單向空轉,反向作功。比方說,依順時鐘方向,該握持部16繞著所述的驅動組件17空轉。順著逆時鐘方向,該握持部16帶動所述的驅動組件17同向旋轉,傳遞該手工具10的一個扭矩。因此,該手工具10又稱棘輪扳手。The
至於,該驅動組件17的具體構造,非本發明的技術特徵,故不予贅述。As for the specific structure of the
其次,所述火星塞套筒11(見第2圖)的一端陷入一個方孔12,所述方孔12的四個平面各有一個珠穴13。所述火星塞套筒11的另端形成一個六角孔14,該六角孔14與所述的方孔12相通,能套住尺寸規格相符的火星塞(圖未示)。Secondly, one end of the spark plug sleeve 11 (see FIG. 2) is sunk into a
如第2〜4圖所示,本實施例的接桿20包括:一根搖桿21、一個接頭30、一根銷40、一片環片41、一個滾動件42、一根芯軸45、一個扣件47、一個壓縮彈簧48、一顆鋼球49與一個支撐件56。As shown in Figures 2 to 4, the connecting
其中,該搖桿21頂端具備另個方孔23而成為一個套接部22。所述搖桿21的底端有一顆球頭24,該球頭24與所述搖桿21之間形成一個頸部25。所述球頭24的內部形成二個擴張孔27,每個擴張孔27具備一個寬端63和一個窄端64。二該窄端64相向連成一個長孔29,該長孔29在所述球頭24的內部中央。二該寬端63位於所述球頭24外部的圓周面,多條斜邊65從所述球頭24的外表延伸至該長孔29。The top of the
其次,所述接頭30的一端突出一根方柱34,從該方柱34至所述接頭30的另端是相連的一個直孔33、一個主孔32與一個圓槽31。該圓槽31的直徑最大,一個肩部38在所述圓槽31的底部,並環繞所述主孔32的出口周圍。該直孔33的直徑最小,故該主孔32的一個底面37環繞所述直孔33的出口。另外,一個孔51(見第6圖)形成於所述方柱34的側邊而與該直孔33相交。Secondly, a
在本實施例,該銷40固定所述接頭30圍成該圓槽31的壁,並穿過所述球頭24的長孔29和擴張孔27。以銷40為中心,該球頭24置入所述的圓槽31而與該接頭30相互轉動。換句話說,該搖桿21連到所述接頭30而能相互擺動。該頸部25的直徑小於所述搖桿21的直徑,故該搖桿21與所述接頭30的擺動幅度相對擴大。In this embodiment, the
在擺動方位,該長孔29繞著該銷40圓周運動,故該搖桿21相對所述的接頭30來回擺動。所述擴張孔27的斜邊65至該銷40形成一個角度,允許該搖桿21沿著箭頭28方向往所述銷40的兩端來回擺動。In the swinging position, the
在本實施例,該支撐件56是一個圓錐彈簧,該圓錐彈簧置入所述的圓槽31,其二端分別接觸該球頭24外表與所述圓槽31的肩部38。因此,該支撐件56推動所述的球頭24和該接頭30分開。該銷40阻擋所述長孔29的最低點,使該搖桿21與所述的接頭30相互拉扯而維持一個張力。In this embodiment, the
某些實施例中,該支撐件56是多個堆疊的簧片、一個壓縮彈簧,或是其他的彈性元件。In some embodiments, the
另外,該環片41束緊所述接頭30的壁外部,阻止該銷40脫離所述的接頭30,預防該接桿20解體。In addition, the
再者,該扣件47鑲嵌所述芯軸45的一端。所述芯軸45的另端穿過該壓縮彈簧48,經由所述的主孔32進入該直孔33。該壓縮彈簧48二端分別接觸所述主孔32的底面37與該扣件47,能擠壓該壓縮彈簧48累積一個作用力53。因此,該作用力53與所述壓縮彈簧48的一個變形量成正比。Furthermore, the
其中,所述芯軸45的側邊形成一個位階部46,能推動該鋼球49進入所述方柱34的孔51(見第6圖)。該鋼球49的局部露出所述方柱34的外表,同時卡住該位階部46,使該芯軸45抗衡所述壓縮彈簧48的作用力53。The side of the
在本實施例,所述滾動件42是一顆剛性的球體,該球體滾動接觸所述芯軸45的端面。借助所述壓縮彈簧48的作用力53,該芯軸45推動該滾動件42朝向所述接頭30的圓槽31移動。一個直徑縮減端36形成於所述主孔32通過該圓槽31的出口,該直徑縮減端36的直徑小於所述滾動件42的直徑,故該滾動件42受阻於所述主孔32的直徑縮減端36,讓局部的滾動件42超越該肩部38而露出所述的圓槽31。同時,該滾動件42至所述球頭24的外表相隔一個距離67,短於該銷40至所述長孔29的最高點的距離66。In this embodiment, the rolling
從第5圖能夠理解,一個外力54施予該搖桿21,縮短該搖桿21與該接頭30彼此的距離。所述長孔29的最高點抵制該銷40,從該銷40至所述長孔29的最低點的一個行程69,相當該搖桿21沿直線運動的距離。該球頭24進入所述圓槽31的深處而靠近該肩部38,壓縮該支撐件56體積的同時,並與所述滾動件42的外表形成一個接觸點68。該滾動件42退入所述的主孔32,持續帶動該芯軸45相對所述接頭30同向位移。此刻,該扣件47靠近所述主孔32的底面37而擠壓該壓縮彈簧48,相對增加所述壓縮彈簧48的變形量。As can be understood from FIG. 5 , an
接著看到第6圖,該芯軸45伸出所述方柱34的端面,讓所述位階部46的低階部位面對該孔51。此刻,該鋼球49是自由的,可向著該芯軸45退入所述位階部46的低階部位,故所述方柱34的外表沒有鋼球49。Next, as shown in FIG. 6 , the
俟方柱34***方孔12後,以人力主動拉起該搖桿21。或者,藉助所述支撐件56回復原狀的力量,被動地推開該搖桿21與所述接頭30。同時,回復原狀的壓縮彈簧48會釋放作用力53(參閱第3圖),透過該扣件47間接推動所述的芯軸45,連帶所述滾動件42的局部超越該肩部38,而能露出所述的圓槽31。因為所述位階部46的高階部位正對該孔51(參閱第7圖),所以該鋼球49被所述的高階部位再次推出該方柱34外,卡掣相應的珠穴13,完成該接桿20結合所述火星塞套筒11的動作。After the
回頭看到第1、2圖,該頭部15下方是所述驅動組件17的超出部件,能***所述套接部22的方孔23。如此,該接桿20將所述手工具10的扭矩傳遞至該火星塞套筒11,鎖緊火星塞執行安裝作業,或是旋鬆的拆卸作業。Looking back at Figures 1 and 2, below the
第7圖繪製所述接桿20的第二實施例,其構造大致相同於第一實施例,差異處在於:首先,沒有滾動件和扣件。該芯軸45多了一個大直徑部70。該大直徑部70形成於所述芯軸45的端部,而具備一個凸曲面71與一個抵制面72。其中,該抵制面72是圍繞所述芯軸45的一個環形面,該環形面在所述主孔32的內部,其與該底面37分別接觸所述壓縮彈簧48的二端,改變所述壓縮彈簧48的變形量以及作用力53。第二實施例的大直徑部70取代第一實施例的扣件,無損所述接桿20的功效。FIG. 7 shows a second embodiment of the connecting
再者,該壓縮彈簧48的作用力53,推動所述大直徑部70的凸曲面71直接頂住該直徑縮減端36,連帶局部的凸曲面71超越該肩部38,從而露出所述的圓槽31中。Furthermore, the
如第8圖所示,該凸曲面71至所述球頭24外表的距離67,比該銷40到所述長孔29的最高點的距離66還要短。在第9圖中,該搖桿21接受外力54後,其與所述大直徑部70的凸曲面71產生接觸點68,二者依直線運動的距離,相當該銷40至所述長孔29的最低點的行程69。因此,第二實施例的大直徑部70取代第一實施例的滾動件,無損所述接桿20的功效。As shown in FIG. 8 , the
在不背離本案廣義的概念下,熟習此項技術者能理解,並對上開的實施例進行改變。因此,本案不限於說明書揭示的特定實施例,舉凡根據本案精神與技術範疇所為的修改,均應為申請專利範圍界定的文字內容所涵蓋和保護。Without departing from the broad concept of this case, those skilled in the art can understand and make changes to the above embodiments. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and all modifications made according to the spirit and technical scope of this case should be covered and protected by the text content defined in the scope of the patent application.
