Abstract
Description
本發明涉及手工具的警示裝置,特別是指一種扭力扳手,關於扭矩調節關閉或開啟的提醒或警告裝置。The invention relates to a warning device for a hand tool, in particular to a torque wrench, a reminder or warning device for turning off or on the torque adjustment.
已知的扭力扳手有一個支持件,該支持件一端樞接一個頭,另端固定一個握把。所述的樞接構造包括:一個臂和一根軸,該臂自頭往外延伸一定長度,進而***中空的支持件。該軸通常是指鉚釘,該鉚釘穿過支持件與臂,支持臂深入支持件的端部接觸一個響輪的單邊。該響輪另側滾動接觸一個壓制塊,該壓制塊推動響輪觸及臂的動力源,來自一個埋設在支持件裡面的壓縮彈簧。The known torque wrench has a support member, one end of the support member is pivotally connected with a head, and the other end is fixed with a grip. The pivotal connection structure includes: an arm and a shaft, and the arm extends a certain length outward from the head, and then is inserted into the hollow support member. The shaft usually refers to a rivet that penetrates the support member and the arm, and the support arm penetrates into the end of the support member to contact a single side of a rattle. The other side of the rattle is in rolling contact with a pressing block, and the pressing block pushes the rattle to touch the arm. The power source comes from a compression spring embedded in the support.
在使用時,該頭直接的或間接的結合一個工件,譬如螺絲、螺栓或螺帽。該頭到握把的距離乘以使用者施予握把的一個作用力,得到扭力扳手驅使工件轉動的一個扭矩(或稱力矩)。該扭矩與工件的一個反作用力在響輪相遇,在扭矩大於或等於反作用力時,該工件繼續進行鎖緊或旋鬆作業。倘若扭矩小於反作用力,該臂脫離響輪,中斷扭矩至工件的傳遞,避免螺牙結構受到外力破壞。In use, the head directly or indirectly joins a workpiece, such as a screw, bolt or nut. The distance from the head to the grip is multiplied by a force applied by the user to the grip to obtain a torque (or torque) that the torque wrench drives the workpiece to rotate. The torque and a reaction force of the workpiece meet at the rattle. When the torque is greater than or equal to the reaction force, the workpiece continues to be locked or loosened. If the torque is less than the reaction force, the arm is separated from the rattle, interrupting the transmission of torque to the workpiece, and avoiding damage to the screw structure by external forces.
但是,先前技術不會告訴使用者一件事,就是扭矩調節功能是開啟的或關閉的。故扭力扳手的使用,存在危險性。However, the prior art does not tell the user one thing, that is, whether the torque adjustment function is on or off. Therefore, the use of torque wrenches is dangerous.
鑑於此,本案發明人提出一種警示裝置,主要目的在於:採用合併、分離顯現不同顏色的結構,警告或提醒使用者注意,扭矩的調節功能關閉或開啟,降低危險的發生率,相對提昇扭力扳手的使用安全性。In view of this, the inventor of the present case proposes a warning device, the main purpose of which is to use a structure that combines and separates showing different colors to warn or remind the user that the torque adjustment function is turned off or on, reducing the incidence of danger, and relatively improving the torque wrench The safety of use.
源於上述目的之達成,本發明包括:From the achievement of the above objectives, the present invention includes:
一個扭力扳手配置一個握把,該握把具備一個正齒輪;A torque wrench is equipped with a grip, and the grip has a spur gear;
一個旋鈕具備一個外齒輪,該旋鈕配置扭力扳手使外齒輪面對正齒輪;A knob is equipped with an external gear, the knob is equipped with a torque wrench so that the external gear faces the spur gear;
一個調節鈕有一個後段,該後段外側有一組直齒,該調節鈕內側的一個內齒輪延伸至後段,該內齒輪卡掣正齒輪和外齒輪視為一個鎖住位置,該旋鈕外側的圓周面露出調節鈕顯示扭矩不可調節的顏色;解除正齒輪的卡掣關係,界定內齒輪咬住外齒輪為一個解鎖位置,該調節鈕遮蔽旋鈕的圓周面,二者相對握把同向轉動;An adjusting button has a rear section, and the outer side of the rear section has a set of straight teeth. An internal gear on the inside of the adjusting button extends to the rear section. The internal gear engages the spur gear and the external gear as a locked position. The outer circumferential surface of the knob Expose the adjusting button to show the unadjustable color of the torque; release the blocking relationship of the spur gear, and define the internal gear biting the external gear as an unlocking position. The adjusting button covers the circumferential surface of the knob, and the two rotate in the same direction relative to the grip;
一個刻度環內側形成一組直齒,在鎖住位置時,該刻度環在握把與旋鈕之間彼此緊靠在一起,在解鎖位置時,該刻度環單側離開握把或旋鈕,該組直齒在鎖住與解鎖二位置皆與調節鈕的直齒保持嚙接關係;以及A set of straight teeth is formed on the inner side of a scale ring. When in the locked position, the scale ring is close to each other between the handle and the knob. When in the unlocked position, the scale ring leaves the handle or knob on one side, and the group is straight. The teeth maintain a meshing relationship with the straight teeth of the adjusting button in both the locked and unlocked positions; and
具備不同於旋鈕顏色的一條色環,在鎖住位置時,該色環被刻度環遮蔽;在解鎖位置時,該色環出現於刻度環單側。It has a color ring that is different from the color of the knob. In the locked position, the color ring is covered by the scale ring; in the unlocked position, the color ring appears on one side of the scale ring.
如此,本發明的調節鈕就像是開關一樣,採用合併狀態顯現鎖住位置的顏色(如紅色),或是以分離狀態表現解鎖位置的顏色(如綠色),警告或提醒使用者注意,扭矩的調節功能關閉或開啟,降低危險的發生率,相對提昇扭力扳手的使用安全性。In this way, the adjusting button of the present invention is like a switch. It adopts the color that shows the locked position in the combined state (such as red), or the color that shows the unlocked position in the separated state (such as green) to warn or remind the user. The adjustment function is turned off or on, which reduces the incidence of danger and relatively improves the safety of the use of torque wrenches.
為使本發明之目的、構造、特徵和優點,更加淺顯易懂,茲舉一個或以上的較佳實施例,配合所附的圖式詳細說明如下。In order to make the purpose, structure, features, and advantages of the present invention more simple and understandable, one or more preferred embodiments are described in detail below in conjunction with the accompanying drawings.
第1圖是平面圖,繪製扭力扳手10的第一實施例。該扭力扳手10一端是一個驅動結構11,另端配置一個調節機構18,二者被一個支持件12連在一起。該支持件12是中空的,其內部組裝一個扭矩機構15。一個握把16固定支持件12外部毗鄰調節機構18。Fig. 1 is a plan view showing the first embodiment of the
該驅動結構11有一個頭部14,該頭部14延伸一根臂13,該臂13***支持件12,二者維持樞接關係。該扭矩機構15包括一個響輪19與一個壓縮彈簧21,該響輪19和臂13深入支持件12的端部樞接一根連桿17。所述的調節機構18包括一根傳動桿43,該傳動桿43一端結合一個旋鈕40同向轉動,另端外側形成一段螺牙47,螺接一個管體46內側的一段螺牙48。該管體46抵住壓縮彈簧21,該壓縮彈簧21的一個作用力推動響輪19往臂13方向移動,該臂13支持頭部14露出支持件12外部不輕易擺動。The
一名使用者(圖未繪)握緊握把16,操作驅動結構11對一個工件(圖未繪)施予一個扭矩,執行鎖緊或旋鬆作業。同時,該工件的一個反作用力經由頭部14傳遞至臂13,抗衡壓縮彈簧21輸出響輪19的作用力。當反作用力小於作用力,該頭部14持續工件的鎖緊或旋鬆作業。當反作用力大於作用力,該臂13推開響輪19,中斷頭部14傳輸至工件的扭矩。A user (not shown in the figure) grips the
換句話說,該壓縮彈簧21的作用力愈大,該頭部14傳輸至工件的扭矩愈強。因此,該壓縮彈簧21的作用力與頭部14的扭矩成正比。In other words, the greater the force of the
接著看到第3圖,所述的傳動桿43安裝在一個支撐構造44,在支持件12裡面只能轉動,卻不能沿著軸心方向位移。另外,該管體46在支持件12內部無法轉動,卻能沿著軸心方向來回移動,故管體46將傳動桿43的旋轉動能轉換為直線運動的位能,改變壓縮彈簧作用力的大、小,決定頭部傳輸扭矩的強、弱。Then see Fig. 3, the
在傳動桿43支持下,該旋鈕40的一個外齒輪52,面對握把16的一個前段45外部所形成一個正齒輪37。另外,一個蓋子42封住旋鈕40的端面,避免灰塵或污物入侵旋鈕40的內部。Supported by the
所述的調節機構還有一個刻度環32與一個調節鈕33。其中,該調節鈕33套在旋鈕40外部,並往握把16方向延伸一個後段38,該調節鈕33內側的一個內齒輪50延伸至後段38,該內齒輪50卡掣正齒輪37和外齒輪52視為一個鎖住位置。The adjustment mechanism also has a
在鎖住位置時,該正齒輪37具備阻擋作用,禁止該調節鈕33帶動旋鈕40相對支持件12(或握把16)轉動。而且,該後段38外側形成一組直齒54,嚙接刻度環32內側的一組直齒56,致使刻度環32配合調節鈕33保持靜止不動狀態。When in the locked position, the
值得注意的是,該旋鈕40外側的圓周面41露出調節鈕33。同時,該刻度環32在握把16與旋鈕40之間彼此緊靠在一起,以刻度環32遮蔽後段38的一條色環36。It is worth noting that the outer
原則上,該圓周面41的顏色選擇暗色系,如綠色、藍色或灰色,顯示扭矩不可調節的狀態,提醒使用者放心使用扭力扳手。該色環36的顏色選擇醒目色系,如紅色、黃色或白色,展現扭矩可調節的狀態,警告使用者不要使用扭力扳手為宜。In principle, the color of the
在本實施例,該圓周面41的顏色,源自旋鈕40製作成分本身的色澤。某些實施例中,該圓周面41的顏色,來自旋鈕40外表的一層貼紙、薄膜或其他附著物。In this embodiment, the color of the
在本實施例,該色環36是束帶,該束帶套在調節鈕33的一個槽39(見第4圖)。某些實施例中,該色環36是塗料,該塗料噴塗在調節鈕33外表。In this embodiment, the
另外,一個聯結件35設在前段45根部到握把16外表間,將一個透明蓋34結合握把16固定不動,致使透明蓋34能夠罩住刻度環32。In addition, a connecting
第2圖是平面圖,表現放大的握把16外表具備一個扭矩顯示器20與一個箭頭部30。其中,該扭矩顯示器20規劃透明的一個直條22,該直條22單邊的一組刻度24對照一個有色段28,能夠判讀扭力扳手10關於公制單位的扭矩值。該直條22另側的一組刻度26,代表英制單位的扭矩值。所述的扭矩值是小數點前面的整數,配合箭頭部30指向刻度環32外側的一組刻度(未標號)與一組數字31之一,取得小數點後面的數值,能夠精確瞭解扭力扳手10實際的扭矩值。FIG. 2 is a plan view, and the outer surface of the
此處所稱的有色段28,泛指該名使用者通過扭矩顯示器20目視一層附著管體46(見第3圖)外表的塗料。The
如第4、5圖所示,解除正齒輪37的卡掣關係,界定該內齒輪50咬住外齒輪52為一個解鎖位置。在解鎖位置時,該調節鈕33遮蔽旋鈕40的圓周面41,二者相對握把16同向轉動,透過螺牙47、48的嚙接關係,該傳動桿43帶動管體46相對支持件12(或握把16)直線位移,改變扭力扳手的扭矩值。該透明蓋34阻止刻度環32隨著後段38直線位移,卻不干涉調節鈕33帶動刻度環32同向轉動,使色環36出現於刻度環32單側。因此,該色環36出現在分開的刻度環32與調節鈕33之間。As shown in Figures 4 and 5, the blocking relationship of the
第6圖表現警示裝置的第二實施例,其結構大致相同於第一實施例,差異處在於:在解鎖位置時,該色環36出現在分開的刻度環32和握把16之間。在不影響正齒輪正常運作的條件下,該色環36設在握把16的前段45外部。FIG. 6 shows the second embodiment of the warning device. Its structure is roughly the same as that of the first embodiment. The difference is that the
其次,該聯結件35使透明蓋34結合於調節鈕33,用以罩住刻度環32。該透明蓋34方向是相反的,既不干涉調節鈕33帶動刻度環32同向轉動,又能限制刻度環32隨著調節鈕33直線位移。Secondly, the connecting
