Description

用於扭矩調節的警示裝置Warning device for torque adjustment

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 torque wrench 10. The torque wrench 10 has a driving structure 11 at one end and an adjusting mechanism 18 at the other end, and the two are connected by a support 12. The supporting member 12 is hollow, and a torque mechanism 15 is assembled therein. A grip 16 fixes the support 12 adjacent to the adjustment mechanism 18 outside.

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 driving structure 11 has a head 14, the head 14 extends an arm 13, the arm 13 is inserted into the support 12, and the two maintain a pivotal relationship. The torque mechanism 15 includes a rattle 19 and a compression spring 21, and the rattle 19 and the arm 13 penetrate into the end of the support 12 to pivotally connect a connecting rod 17. The adjusting mechanism 18 includes a transmission rod 43, one end of the transmission rod 43 is combined with a knob 40 to rotate in the same direction, and the other end is formed with a thread 47 on the outer side, which is screwed to a thread 48 on the inner side of the tube body 46. The tube 46 resists the compression spring 21, and a force of the compression spring 21 pushes the rattle 19 to move toward the arm 13, and the arm 13 supports the head 14 to expose the outside of the support 12 and does not swing easily.

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 grip 16 and operates the driving structure 11 to apply a torque to a workpiece (not shown in the figure) to perform a locking or unscrewing operation. At the same time, a reaction force of the workpiece is transmitted to the arm 13 through the head 14, and the force of the rattle 19 is outputted by the compression spring 21 against the balance. When the reaction force is less than the acting force, the head 14 continues to lock or loosen the workpiece. When the reaction force is greater than the acting force, the arm 13 pushes away the rattle 19, interrupting the torque transmitted by the head 14 to the workpiece.

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 compression spring 21, the stronger the torque transmitted by the head 14 to the workpiece. Therefore, the force of the compression spring 21 is proportional to the torque of the head 14.

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 transmission rod 43 is installed in a supporting structure 44, and can only rotate in the supporting member 12, but cannot move along the axis direction. In addition, the tube body 46 cannot rotate inside the support 12, but can move back and forth along the axial direction. Therefore, the tube body 46 converts the rotational kinetic energy of the transmission rod 43 into the potential energy of linear motion, thereby changing the force of the compression spring. , Small, determine the strength or weakness of the torque transmitted by the head.

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 transmission rod 43, an external gear 52 of the knob 40 forms a spur gear 37 facing the outside of a front section 45 of the handle 16. In addition, a cover 42 seals the end surface of the knob 40 to prevent dust or dirt from entering the interior of the knob 40.

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 scale ring 32 and an adjustment button 33. Wherein, the adjusting button 33 is sleeved on the outside of the knob 40 and extends a rear section 38 in the direction of the handle 16. An internal gear 50 inside the adjusting button 33 extends to the rear section 38, and the internal gear 50 locks the spur gear 37 and the external gear. 52 is considered a locked position.

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 spur gear 37 has a blocking function, which prohibits the adjustment button 33 from driving the knob 40 to rotate relative to the support 12 (or the grip 16). Moreover, a set of straight teeth 54 is formed on the outer side of the rear section 38, which engages a set of straight teeth 56 on the inner side of the scale ring 32, so that the scale ring 32 cooperates with the adjusting button 33 to remain stationary.

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 circumferential surface 41 of the knob 40 exposes the adjusting knob 33. At the same time, the scale ring 32 is close to each other between the handle 16 and the knob 40, and a color ring 36 of the rear section 38 is covered by the scale ring 32.

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 circumferential surface 41 is selected from dark colors, such as green, blue or gray, to show the state that the torque is not adjustable, and to remind the user to use the torque wrench with confidence. The color of the color circle 36 is selected from the eye-catching color system, such as red, yellow or white, to show the state of adjustable torque, and it is advisable to warn the user not to use a torque wrench.

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 circumferential surface 41 is derived from the color of the knob 40 itself. In some embodiments, the color of the circumferential surface 41 comes from a layer of sticker, film or other attachments on the outer surface of the knob 40.

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 color ring 36 is a belt, and the belt is sleeved in a groove 39 of the adjusting button 33 (see Fig. 4). In some embodiments, the color wheel 36 is paint, and the paint is sprayed on the outer surface of the adjusting knob 33.

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 member 35 is arranged between the root of the front section 45 and the outer surface of the grip 16, and a transparent cover 34 is fixed in conjunction with the grip 16 so that the transparent cover 34 can cover the scale ring 32.

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 grip 16 showing an enlarged view is provided with a torque display 20 and an arrow portion 30. Wherein, the torque display 20 is designed with a transparent straight bar 22, and a set of scales 24 on one side of the straight bar 22 is compared with a colored segment 28 to be able to interpret the torque value of the torque wrench 10 in metric units. A set of scales 26 on the other side of the bar 22 represents the torque value in English units. The torque value is an integer before the decimal point. With the arrow 30 pointing to one of a set of scales (not labeled) and a set of numbers 31 outside the scale ring 32, the value after the decimal point can be obtained to accurately understand the torque wrench 10 The actual torque value.

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 colored section 28 referred to here generally refers to the user who visually observes a layer of paint attached to the surface of the tube body 46 (see Figure 3) through the torque display 20.

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 spur gear 37 is released, and the internal gear 50 bites the external gear 52 as an unlocked position. In the unlocked position, the adjusting button 33 covers the circumferential surface 41 of the knob 40, and the two rotate in the same direction relative to the grip 16. Through the engagement relationship of the threads 47 and 48, the transmission rod 43 drives the tube 46 relative to the support 12 (Or grip 16) linear displacement to change the torque value of the torque wrench. The transparent cover 34 prevents the scale ring 32 from linearly shifting with the rear section 38, but does not interfere with the adjustment knob 33 driving the scale ring 32 to rotate in the same direction, so that the color ring 36 appears on one side of the scale ring 32. Therefore, the color ring 36 appears between the divided scale ring 32 and the adjustment knob 33.

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 color ring 36 appears between the separate scale ring 32 and the grip 16 when in the unlocked position. Under the condition that the normal operation of the spur gear is not affected, the color ring 36 is arranged outside the front section 45 of the grip 16.

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 member 35 connects the transparent cover 34 to the adjusting button 33 to cover the scale ring 32. The direction of the transparent cover 34 is opposite, which neither interferes with the adjustment button 33 driving the scale ring 32 to rotate in the same direction, but also limits the linear displacement of the scale ring 32 with the adjustment button 33.
