Description
本發明涉及一種工具的扭矩調整技術。 The present invention relates to a torque adjustment technique for a tool.
已知的工具,如扭矩扳手、扭矩起子。某些工具的扭矩值,通常被一扭矩調節裝置控制。選擇適當的扭矩值,可在一定的範圍,以工具帶動一緊固件(如螺栓或螺帽等)同向轉動,執行旋鬆或鎖緊作業。倘若超出預設範圍,扭矩調節裝置會跳脫,以致工具無法驅使緊固件繼續轉動,避免造成崩牙的毀損後果,導致拆卸無效等問題。 Known tools such as torque wrenches, torque drivers. The torque value of some tools is usually controlled by a torque adjustment device. Selecting the appropriate torque value can be used to drive a fastener (such as a bolt or a nut) in the same direction to perform a loosening or locking operation. If it exceeds the preset range, the torque adjustment device will trip, so that the tool can not drive the fastener to continue to rotate, to avoid the damage caused by the collapse of the tooth, resulting in invalid disassembly.
傳統的扭矩調節裝置,種類繁多。某個扭矩調節裝置由一旋鈕與一控制環組成,旋鈕外壁環列一圈齒條,控制環內壁也有一圈齒條,這些齒條長度方向與控制環軸心大致平行,彼此嚙合且限制旋鈕不得轉動。當旋鈕受力外拉,脫離齒條的嚙合範圍後,才能轉動地調整工具的扭矩值大小。旋鈕再度壓入控制環,使扭矩值不得任意改變。 There are many types of conventional torque adjustment devices. A torque adjusting device is composed of a knob and a control ring. The outer wall of the knob is arranged in a ring of racks, and the inner wall of the control ring also has a ring of racks. The length direction of the racks is substantially parallel with the axis of the control ring, and meshes with each other and limits. The knob must not be rotated. When the knob is pulled out and pulled out of the meshing range of the rack, the torque value of the tool can be adjusted rotationally. The knob is pressed into the control ring again so that the torque value cannot be changed arbitrarily.
旋鈕安裝一珠體,珠體被一彈性作用力往旋鈕外頂。在旋鈕壓入期間,控制環壓制珠體,對旋鈕形成一定的阻力。在旋鈕外拉期間,珠體失去控制環的限制,容易彈出旋鈕外,甚至於消失不見,對扭矩的調節影響甚鉅。 The knob is mounted with a bead body, and the bead body is elastically biased to the top of the knob. During the press-in of the knob, the control ring presses the beads and forms a certain resistance to the knob. During the pull-out of the knob, the bead loses the limitation of the control loop, and it is easy to pop out of the knob, and even disappears, which has a great influence on the adjustment of the torque.
為了解決這個問題,本案發明人申請取得臺灣第M371616號「扳手扭力值調節機構改良」專利權,在案可稽。 In order to solve this problem, the inventor of this case applied for the patent right of Taiwan's M371616 "Improvement of Wrench Torque Value Adjustment Mechanism", which is well documented.
但是,本案發明人不因此自滿,秉持精益求精的精神,戮力 於工具相關構造的持續研發,終於發明出一種新的扭矩調節裝置。 However, the inventor of this case is not complacent and upholds the spirit of excellence. In the continuous development of tool-related construction, a new torque adjustment device was finally invented.
本發明主要目的在於:提供一種卡掣結構,以新的模式取代舊的扭矩調節裝置,改變拉出及壓入的使用習慣,讓扭矩調整作業更為輕鬆且便利。 The main object of the present invention is to provide a cassette structure, replace the old torque adjustment device with a new mode, and change the habit of pulling out and pressing in, making the torque adjustment operation easier and more convenient.
緣於上述目的之達成,本發明提供的扭矩調節裝置,包括一套筒、一主體、一操作桿與一卡掣單元。其中,該套筒有多個內齒,這些內齒環列套筒內壁上。該主體局部置入套筒,主體有一凸部和至少一凹部,凹部陷入主體面對內齒處,凸部外露於套筒,其中央形成一直孔,直孔與凹部相通。該操作桿局部置入凸部的直孔,操作桿樞接凸部,並在面對凹部處形成一容納部。 For the above purposes, the torque adjustment device provided by the present invention comprises a sleeve, a main body, an operating rod and a cassette unit. Wherein, the sleeve has a plurality of internal teeth which are arranged on the inner wall of the sleeve. The main body is partially inserted into the sleeve, and the main body has a convex portion and at least one concave portion. The concave portion is recessed into the main body facing the inner tooth, and the convex portion is exposed to the sleeve, and a center is formed with a straight hole, and the straight hole communicates with the concave portion. The operating rod is partially inserted into the straight hole of the convex portion, and the operating rod pivotally connects the convex portion and forms a receiving portion at the facing concave portion.
所述的卡掣單元,其包括至少一卡掣塊、至少一殼及一彈性件。該卡掣塊置入主體的凹部,卡掣塊樞接主體,並在面對套筒的內齒處形成至少一外齒。該殼可進出於操作桿的容納部,用以罩住彈性件一端。該彈性件另端置入操作桿的容納部,以彈性件推動殼觸及卡掣塊相應的部位。 The cassette unit includes at least one cassette block, at least one shell and an elastic member. The latching block is placed in a recess of the body, the latching block pivoting the body and forming at least one external tooth at the internal teeth facing the sleeve. The housing can be inserted into the receiving portion of the operating lever to cover one end of the elastic member. The elastic member is inserted into the receiving portion of the operating rod at the other end, and the elastic member pushes the shell to touch the corresponding portion of the latching block.
當操作桿相對主體移到一限制位置時,卡掣塊被殼推動,使外齒嚙合套筒相應的內齒,以致主體不得相對套筒旋轉。當操作桿相對主體移到一自由位置時,卡掣塊被殼推動,使外齒遠離套筒的內齒,主體相對套筒自由轉動。 When the operating lever is moved relative to the main body to a restricted position, the latching block is pushed by the housing such that the external teeth engage the corresponding internal teeth of the sleeve so that the body does not rotate relative to the sleeve. When the operating lever is moved relative to the main body to a free position, the latching block is pushed by the housing so that the external teeth are away from the internal teeth of the sleeve, and the main body is free to rotate relative to the sleeve.
一種工具,其包括一操作頭、一握把、一扭矩結構與所述的扭矩調節裝置。該扭矩結構包括:一柄、一臂、一傳動桿、一從動件、一壓縮彈簧及一輪座。其中,該柄與握把相連,其內部中空,供傳動桿安裝於柄內而可自轉運動。該臂與操作頭設計成為一體,其***柄且二者維持 樞接關係。該從動件置入柄內,其螺接於傳動桿而可相對柄往復運動。壓縮彈簧置入柄內,其一端與從動件相抵,另端頂住輪座,支持輪座觸及臂深入柄的部位。 A tool includes an operating head, a grip, a torque structure and the torque adjustment device. The torque structure comprises: a handle, an arm, a transmission rod, a follower, a compression spring and a wheel seat. Wherein, the handle is connected with the grip, and the inside is hollow, and the transmission rod is installed in the handle and can rotate and rotate. The arm is integrated with the operating head, which is inserted into the handle and both are maintained Pivot relationship. The follower is inserted into the handle and is screwed to the transmission rod to reciprocate relative to the handle. The compression spring is placed in the handle, one end of which is opposite to the driven member, and the other end is placed against the wheel base to support the position where the wheel seat contacts the arm and penetrates the handle.
前述扭矩調節裝置中,套筒置入握把而與柄結合在一起,以主體連接傳動桿且能同向旋轉。 In the above torque adjusting device, the sleeve is placed in the grip and coupled with the handle to connect the transmission rod with the main body and to rotate in the same direction.
當操作桿相對主體移到限制位置時,握把連同柄與套筒保持不動狀態,在卡掣塊嚙合套筒的條件下,主體限制傳動桿不得驅使從動件位移。 When the operating rod is moved relative to the main body to the restricted position, the grip is held in contact with the sleeve and the sleeve, and the main body restraining transmission rod is not allowed to displace the driven member under the condition that the clamping block engages the sleeve.
當操作桿相對主體移到自由位置時,卡掣塊不再受阻於套筒,以致從動件被主體驅動而相對柄往復位移。 When the operating lever is moved relative to the main body to the free position, the latching block is no longer blocked by the sleeve, so that the driven member is driven by the main body to be reciprocally displaced relative to the shank.
如此,在操作桿聯結一按鈕,按鈕宛如蹺蹺板般偏擺,控制操作桿來回擺動,取得扭矩的調整功能。或者,操作桿連接一推鈕,推鈕來回滑動,同樣能夠決定操作桿調節扭矩值。無論是擺動或滑動的模式,皆可取代舊的拉出、壓入等使用習慣,讓扭矩調整變得更為輕鬆及便利。 In this way, when the operating lever is coupled with a button, the button is swayed like a seesaw, and the operating lever is controlled to swing back and forth to obtain a torque adjustment function. Alternatively, the operating lever is connected to a push button, and the push button is slid back and forth, and the operating lever can also be adjusted to adjust the torque value. Whether it is a swing or slide mode, it can replace the old use of pull-out, press-in, etc., making torque adjustment easier and more convenient.
接著,基於圖式詳述相關的實施例,說明採用之技術、手段及功效,相信本發明上述目的、構造及特徵,當可由之得一深入而具體的瞭解。 The above-mentioned objects, structures, and functions of the present invention will be described with reference to the detailed description of the embodiments.

請參閱第1、2圖,闡明工具一較佳實施例。在本實施例,工具是扳手100,包括一操作頭10、一握把40、一扭矩調節裝置101和一扭矩結構102。在某些實施例,工具是指扭矩式螺絲起子。 Please refer to Figures 1 and 2 for a preferred embodiment of the tool. In the present embodiment, the tool is a wrench 100 including an operating head 10, a grip 40, a torque adjustment device 101 and a torque structure 102. In some embodiments, the tool refers to a torque screwdriver.
在操作頭10下方有一套接部11,以直接或間接方式結合緊固件,如螺栓或螺帽。 Below the operating head 10 there is a set of joints 11 for directly or indirectly joining fasteners such as bolts or nuts.
該握把40有二窗口42、49,每個窗口42、49鑲嵌一形狀大致相符的鏡片21、29,用以透視鏡片21、29下面的物品。其中之一鏡片21規劃兩種不同單位的刻度,配合鏡片21下面一移動的刻度指標件28,利於扭矩值的判讀。此處所稱的刻度單位,如英制單位lb-ft(磅-呎)與公制單位N-m(牛頓-米)。當然,kg-m(公斤-米)單位制度,亦在允許的範圍內。 The grip 40 has two windows 42, 49, each of which is inlaid with a generally compliant lens 21, 29 for seeing the underside of the lenses 21, 29. One of the lenses 21 plans a scale of two different units, and cooperates with a moving scale indicator 28 below the lens 21 to facilitate the interpretation of the torque value. The units of scale referred to here are, for example, the British unit lb-ft (pound-呎) and the metric unit N-m (Newton-meter). Of course, the kg-m (kg-meter) unit system is also within the allowable range.
扳手100的作用力,通過扭矩結構102傳遞至操作頭10的套接部11。其中,扭矩結構102由一柄20、一臂30、一傳動桿34、一從動件35、一壓縮彈簧36及一輪座32組成,茲就各元件概述如下: The force of the wrench 100 is transmitted to the socket portion 11 of the operating head 10 through the torque structure 102. The torque structure 102 is composed of a handle 20, an arm 30, a transmission rod 34, a follower 35, a compression spring 36 and a wheel base 32. The components are summarized as follows:
該柄20與握把40相連,其內部中空且固定有一軸承38,供傳動桿34通過軸承38安裝於柄20內而可自轉運動。該臂30與操作頭10設計成為一體,以從動件35***柄20,二者維持樞接關係。該從動件35置入柄20內,從動件35不僅螺接於傳動桿34,還與前述的刻度指標件28相連,在不受柄20 限制的條件下,從動件35相對柄20往復運動,連帶刻度指標件28同步作動。該壓縮彈簧36置入柄20內,其一端與從動件35相抵,另端頂住輪座32,支持輪座32觸及臂30深入柄20的部位。 The handle 20 is connected to the grip 40, and a bearing 38 is hollowed inside and fixed for the drive rod 34 to be mounted in the handle 20 through the bearing 38 for self-rotation. The arm 30 is integrally formed with the operating head 10, and the follower 35 is inserted into the handle 20, and the two maintain a pivotal relationship. The follower 35 is inserted into the handle 20, and the follower 35 is not only screwed to the transmission rod 34, but also connected to the aforementioned scale indicator member 28, without being stalked 20 Under the limited condition, the follower 35 reciprocates relative to the shank 20, and the scale indicator member 28 is actuated in synchronization. The compression spring 36 is placed in the shank 20, and one end thereof abuts against the follower 35, and the other end bears against the wheel base 32, and the support wheel base 32 touches the portion where the arm 30 penetrates the shank 20.
關於臂30、輪座32與壓縮彈簧36的具體構造,甚至於,彼此間的聯結關係及效能,與臺灣第I300740號、美國第7,182,006號等專利案大致相同。這些專利案與本案屬於同一發明人,故不予贅述。 Regarding the specific configuration of the arm 30, the wheel base 32 and the compression spring 36, even the coupling relationship and the efficiency of each other are substantially the same as those of the patents of Taiwan No. I300740 and U.S. Patent No. 7,182,006. These patents belong to the same inventor as this case and are not described here.
所述的扭矩調節裝置101安裝於握把40內,其位於扭矩結構102後方而與一旋鈕70相連,可以調整扳手100的扭矩值。在第3、4圖中,扭矩調節裝置101由一套筒44、一主體50、一操作桿60及一卡掣單元組成,各元件的細部構造及聯結關係,詳述於后。 The torque adjustment device 101 is mounted in the grip 40 and is located behind the torque structure 102 to be coupled to a knob 70 to adjust the torque value of the wrench 100. In Figures 3 and 4, the torque adjusting device 101 is composed of a sleeve 44, a main body 50, an operating lever 60 and a latching unit, and the detailed structure and coupling relationship of each component are described in detail later.
首先看到第5圖,套筒44中央是一內孔41,內孔41依直徑區分大、小二直徑段43、45。一螺孔47貫穿大直徑段43的壁,並在小直徑段43的壁形成一透孔48。另外,在套筒44內孔41的壁面環列多個內齒46,這些內齒46與套筒44的開口毗鄰。 First, as seen in Fig. 5, the center of the sleeve 44 is an inner hole 41 which divides the large and small diameter sections 43, 45 by diameter. A screw hole 47 penetrates the wall of the large diameter section 43 and forms a through hole 48 in the wall of the small diameter section 43. In addition, a plurality of internal teeth 46 are looped in the wall surface of the bore 41 in the sleeve 44, and these internal teeth 46 are adjacent to the opening of the sleeve 44.
如第6、7圖所示,該主體50一端形成一凹槽51,另端延深一凸部52。在主體50周圍陷入二凹部53,這些凹部53開口相反,緊鄰一***於主體50的凸緣54同一側。在某些實施例,主體50周圍只有一凹部53,亦在允許的範圍內。 As shown in FIGS. 6 and 7, the main body 50 has a groove 51 formed at one end and a convex portion 52 at the other end. Around the body 50 are recessed into two recesses 53, which are oppositely open, immediately adjacent one side of the flange 54 of the body 50. In some embodiments, there is only one recess 53 around the body 50, which is also within the allowable range.
另外,主體50在二凹部53之間有一通孔55,其與一貫穿凸部52中央的直孔58相連,以致通孔55位於凹部53與直孔58的連接處,形成三通的管路。主體50還有一螺孔56和多個結合槽57,螺孔56沿半徑方向形成於凹槽51的壁,這些結合槽57分佈在凸緣54另一側且環繞在凸部52周圍。 In addition, the main body 50 has a through hole 55 between the two recesses 53 and is connected with a straight hole 58 extending through the center of the convex portion 52, so that the through hole 55 is located at the junction of the concave portion 53 and the straight hole 58, forming a three-way pipe. . The main body 50 further has a screw hole 56 and a plurality of coupling grooves 57 which are formed in the radial direction on the wall of the groove 51. The coupling grooves 57 are distributed on the other side of the flange 54 and surround the convex portion 52.
回頭看到第3、4圖,所述的操作桿60有一樞孔61與一容納部62。在本實施例中,容納部62是指貫穿於操作桿60的孔(如第11、13圖)。 在某些實施例,容納部62是陷入操作桿60的槽,亦在允許的範圍內。 Referring back to Figures 3 and 4, the operating lever 60 has a pivot hole 61 and a receiving portion 62. In the present embodiment, the accommodating portion 62 refers to a hole penetrating through the operating lever 60 (as shown in Figs. 11, 13). In some embodiments, the receiving portion 62 is a groove that sinks into the operating rod 60, also within the allowable range.
所述的卡掣單元包括二卡掣塊65、二殼63及一彈性件64,每個殼63宛如中空的彈殼形狀,而彈性件64是壓縮彈簧。這些卡掣塊65的形狀大致相同,每個卡掣塊65外表形成一個或以上的外齒66。 The latch unit includes a second latching block 65, a second housing 63 and an elastic member 64. Each of the housings 63 is shaped like a hollow cartridge, and the resilient member 64 is a compression spring. These latching blocks 65 are substantially identical in shape, with each of the latching blocks 65 forming one or more external teeth 66.
接著看到第8圖,所述的旋鈕70一端陷入一外槽71,另端形成一內艙75。在旋鈕70中間部位形成一中心孔78與多個分佈在中心孔78周圍的結合孔73,允許外槽71與內艙75透過這些孔73、78彼此相通。旋鈕70還有一排內齒76,這些內齒76連續地環列在內艙75的壁面。 Next, as seen in Fig. 8, the knob 70 is inserted into an outer slot 71 at one end and an inner compartment 75 at the other end. A central hole 78 and a plurality of coupling holes 73 distributed around the center hole 78 are formed in the middle portion of the knob 70, allowing the outer groove 71 and the inner casing 75 to communicate with each other through the holes 73, 78. The knob 70 also has an array of internal teeth 76 that are continuously looped around the wall of the inner compartment 75.
從第3~9圖來看扭矩調節裝置101的組裝構造,可知主體50局部置入套筒44,以凸緣54限制主體50***套筒44的深度,以致凸部52露出套筒44外。操作桿60局部置入凸部52的直孔58,用一根樞軸67通過二形成於凸部52的樞孔59,使操作桿60樞接凸部52,以致容納部62位於通孔55且正對著凹部53。 The assembled structure of the torque adjusting device 101 is seen from the third to ninth views. It is understood that the main body 50 is partially inserted into the sleeve 44, and the flange 54 limits the depth at which the main body 50 is inserted into the sleeve 44, so that the convex portion 52 is exposed outside the sleeve 44. The operating rod 60 is partially inserted into the straight hole 58 of the convex portion 52, and the pivoting hole 59 formed in the convex portion 52 is passed through a pivot 67 to pivot the operating rod 60 to the convex portion 52 so that the receiving portion 62 is located in the through hole 55. And facing the recess 53.
將二卡掣塊65置入主體50相應的凹部53。其中,每個卡掣塊65併排於凸緣54側面,二者被一根樞桿68穿過。卡掣塊65與主體50維持樞接關係,使外齒66面對套筒44的內齒46。二殼63罩住彈性件64兩端,以彈性件64被壓縮的模式置入操作桿60的容納部62,在彈性件64推動下,每個殼63局部露出操作桿60的容納部62,從而接觸卡掣塊65相應的部位。 The two latching blocks 65 are placed in the corresponding recesses 53 of the main body 50. Therein, each of the latching blocks 65 is juxtaposed on the side of the flange 54 and is passed by a pivot 68. The latch block 65 maintains a pivotal relationship with the body 50 such that the outer teeth 66 face the inner teeth 46 of the sleeve 44. The two shells 63 cover the two ends of the elastic member 64, and are inserted into the receiving portion 62 of the operating rod 60 in a compressed state of the elastic member 64. Under the pushing of the elastic member 64, each of the shells 63 partially exposes the receiving portion 62 of the operating rod 60. Thereby, the corresponding portion of the latch block 65 is contacted.
旋鈕70的內艙75容納凸緣54,允許凸部52同時通過旋鈕70的中心孔78。旋鈕70的的結合孔73對齊主體50的結合槽57,被緊固件結合在一起,如螺絲74。一按鈕72置入旋鈕70的外槽71,並與操作桿60露出凸部52處鎖固即可。 The inner compartment 75 of the knob 70 receives the flange 54 allowing the projection 52 to simultaneously pass through the central aperture 78 of the knob 70. The coupling holes 73 of the knob 70 are aligned with the coupling grooves 57 of the main body 50 and are joined together by fasteners such as screws 74. A button 72 is inserted into the outer groove 71 of the knob 70 and locked with the operating lever 60 to expose the convex portion 52.
所述的扭矩調節裝置101中,以套筒44置入握把40,遮住柄20與傳動桿34,傳動桿34超出軸承38的部位***主體50的凹槽51中。多個諸 如埋頭螺絲的緊固件之一,通過套筒44的螺孔47而與柄20鎖在一起,另個緊固件穿過套筒44的透孔48且鎖入主體50的螺孔56,迫緊傳動桿34進入凹槽51的部位,以致主體50連接傳動桿34並能同向旋轉。 In the torque adjusting device 101, the sleeve 44 is inserted into the grip 40 to cover the handle 20 and the transmission rod 34, and the transmission rod 34 is inserted into the recess 51 of the main body 50 beyond the bearing 38. Multiple One of the fasteners, such as a countersunk screw, is locked with the shank 20 through the threaded bore 47 of the sleeve 44. The other fastener passes through the through hole 48 of the sleeve 44 and locks into the threaded hole 56 of the body 50. The drive rod 34 enters the portion of the recess 51 such that the body 50 is coupled to the drive rod 34 and is rotatable in the same direction.
此刻,旋鈕70的內齒76環繞在一微調刻度環22外圍。該微調刻度環22外圓周面有多個數字24與若干外齒26(如第9圖),這些外齒26與數字24不在微調刻度環22的同一側,允許外齒26嚙合旋鈕70的內齒76。因為旋鈕70藉由主體50聯結傳動桿34,傳動桿34受阻於軸承38無法外移,所以旋鈕70不得外拉。加上主體50的凸緣54被軸承38擋住,以致旋鈕70不得內壓,只能帶動微調刻度環22沿著順、逆時鐘方向旋轉。 At this point, the internal teeth 76 of the knob 70 surround a periphery of a fine adjustment scale ring 22. The outer circumference of the fine adjustment ring 22 has a plurality of numbers 24 and a plurality of external teeth 26 (as shown in FIG. 9). These external teeth 26 and the number 24 are not on the same side of the fine adjustment ring 22, allowing the external teeth 26 to engage the inside of the knob 70. Teeth 76. Because the knob 70 is coupled to the transmission rod 34 by the main body 50, the transmission rod 34 is blocked from being unable to move outwardly of the bearing 38, so the knob 70 must not be pulled out. In addition, the flange 54 of the main body 50 is blocked by the bearing 38, so that the knob 70 must not be internally pressed, and only the fine adjustment scale ring 22 can be rotated in the forward and reverse clock directions.
使用時,按鈕72上端靠近凸緣54,驅使操作桿60像第10圖虛線般往套筒44下方偏擺,稱為一限制位置。當操作桿60相對主體50移到限制位置時,卡掣塊65被殼63推動,使外齒66嚙合套筒44相應的內齒46,以致主體50不得相對套筒44旋轉,如第11圖。此刻,旋鈕不得轉動。 In use, the upper end of the button 72 is adjacent to the flange 54 to urge the operating lever 60 to yaw downwardly below the sleeve 44 like the dashed line of FIG. 10, referred to as a restricted position. When the operating lever 60 is moved relative to the main body 50 to the restricted position, the latching block 65 is pushed by the housing 63 such that the external teeth 66 engage the corresponding internal teeth 46 of the sleeve 44 such that the body 50 must not rotate relative to the sleeve 44, as shown in FIG. . At this point, the knob must not be rotated.
按鈕72下端靠近凸緣54,驅使操作桿60像第12圖虛線般往套筒44上方偏擺,稱為一自由位置。當操作桿60相對主體50移到自由位置時,卡掣塊65被殼63推動,使外齒66遠離套筒44的內齒46,主體50相對套筒44自由轉動,如第13圖。 The lower end of the button 72 is adjacent to the flange 54 to urge the operating lever 60 to yaw above the sleeve 44 like the dashed line of Fig. 12, referred to as a free position. When the operating lever 60 is moved relative to the main body 50 to the free position, the latching block 65 is pushed by the housing 63 such that the outer teeth 66 are away from the inner teeth 46 of the sleeve 44, and the body 50 is free to rotate relative to the sleeve 44, as shown in FIG.
接著,就調節扭力做進一步說明。如第2~4圖所示,旋鈕70經由主體50帶動傳動桿34旋轉,驅使從動件35對壓縮彈簧36進行擠壓或釋放,從而改變輪座32經由臂30傳遞至操作頭10的作用力,相對影響套接部11施予扭矩的大小,並由刻度指示件28判讀扭矩的改變值。同時,微調刻度環22隨著旋鈕70同步作動,充當扭矩值判讀的輔助數據。 Next, adjust the torque to further explain. As shown in FIGS. 2 to 4, the knob 70 rotates the transmission rod 34 via the main body 50 to drive the follower 35 to press or release the compression spring 36, thereby changing the function of the wheel base 32 to the operation head 10 via the arm 30. The force relatively affects the magnitude of the torque applied by the socket portion 11, and the value of the change in the torque is interpreted by the scale indicator 28. At the same time, the fine adjustment scale ring 22 acts synchronously with the knob 70 to act as auxiliary data for the torque value interpretation.
最後看到第14~16圖,表現扭矩調節裝置的第二實施例,其與第一實施例大致相同,差異處在於:主體50的直孔58是多邊形,其容積大 於操作桿60對應部位的體積。而且,凸部52壁面形成二狹長孔90,每個狹長孔90取代原來的樞孔,容納一***於操作桿60周圍的突柱92。突柱92為多邊形設計,其體積小於狹長孔90容積。 Finally, a second embodiment of the torque adjusting device is shown, which is substantially the same as the first embodiment, except that the straight hole 58 of the main body 50 is polygonal and has a large volume. The volume of the corresponding portion of the operating lever 60. Moreover, the wall portion of the convex portion 52 forms two elongated holes 90, each of which replaces the original pivot hole and accommodates a stud 92 which is raised around the operating rod 60. The stud 92 is a polygonal design having a volume smaller than the volume of the elongated hole 90.
其次,一推鈕80取代原來的按鈕,充當扭矩調節裝置的開關。推鈕80面對扭矩調節裝置處形成一容納槽82,用以連接操作桿60超出主體50的凸部52的部位。因此,推鈕80安裝於旋鈕70的外槽71,帶動操作桿60上、下滑動。 Secondly, a push button 80 replaces the original button and acts as a switch for the torque adjustment device. The push button 80 forms a receiving groove 82 facing the torque adjusting device for connecting the portion of the operating lever 60 beyond the convex portion 52 of the main body 50. Therefore, the push button 80 is mounted on the outer groove 71 of the knob 70 to drive the operating lever 60 to slide up and down.
推鈕80下滑到限制位置,連帶操作桿60相對套筒44移至第14圖虛線處。推鈕80上移到自由位置,使操作桿60移至第15圖虛線處。 The push button 80 slides down to the limit position, and the associated operating lever 60 is moved relative to the sleeve 44 to the dotted line of Fig. 14. The push button 80 is moved up to the free position, and the operating lever 60 is moved to the dotted line of Fig. 15.
綜上所述,僅為本發明之較佳實施例而已,當不能以之限定本發明實施之範圍,故舉凡數值之變更或等效元件之置換,或依本發明申請專利範圍所作之均等變化與修飾,皆應仍屬本發明專利涵蓋之範疇。 In the above, it is only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the numerical values are changed or the equivalent elements are replaced, or the equivalent range of the patent application scope of the present invention is changed. And modifications should still fall within the scope of the invention patent.
