按吾人先前所知,習用之扭力扳手結構,亦為吾人所受讓之專利案,如美國專利案號:US8863624B2,臺灣專利案申請號:103215530,證書號:M492808,專利名稱:具鎖固裝置之扭力扳手,該專利案結構係在於:一種具鎖固裝置之扭力扳手,其包括:一中空之主桿體10;一工具件20;一扭力調整彈性件40;一離合組件50;以及一鎖固裝置60,係設置於該主桿體10之第二端12之外周緣,並於一鎖固位置及一非鎖固位置之間沿著該主桿體10產生相對軸向移動,其中,該鎖固裝置60包括:一金屬製之鎖固環61、一壓縮彈簧62,一金屬製之C型扣63以及至少一金屬製之定位珠65。 According to my previous knowledge, the conventional torque wrench structure is also a patent case that I have been assigned, such as US patent case number: US8863624B2, Taiwan patent case application number: 103215530, certificate number: M492808, patent name: with locking device The torque wrench structure of this patent is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool member 20; a torque adjusting elastic member 40; a clutch assembly 50; and a The locking device 60 is disposed on the outer periphery of the second end 12 of the main rod body 10 and generates relative axial movement along the main rod body 10 between a locked position and an unlocked position, wherein The locking device 60 includes a metal locking ring 61, a compression spring 62, a metal C-shaped buckle 63, and at least one metal positioning bead 65.
但此習用扭力扳手結構之缺失係在於: However, the lack of the conventional torque wrench structure lies in:
1、請輔以美國公報之第6圖至第8圖所示,當欲調整扭力值時,移動該鎖固環61往該調整握把30之方向推撥,使該鎖固裝置60滑移至非鎖固位置上,該壓縮彈簧62因該鎖固環61移位而被壓縮,使該C型扣63卡合於該環槽 614而將鎖固環61定位於非鎖固位置上,但旋動時,該扭力扳手結構係往被旋動件處位移,而該扭力扳手結構位移時,該鎖固環61係易踫撞至其它物體,該鎖固環61受踫撞時,踫撞之力量係為該鎖固環61往該調整握把30之方向,亦即該鎖固環61受踫撞時係會使該鎖固環61自動移位至非鎖固位置處,該扭力扳手結構之該調整握把30即可具有調整扭力之功能而不具有安全性。 1. Please supplement Figures 6 to 8 of the U.S. Gazette. When you want to adjust the torque value, move the locking ring 61 in the direction of the adjusting handle 30 to make the locking device 60 slide. In the non-locking position, the compression spring 62 is compressed due to the displacement of the locking ring 61, so that the C-shaped buckle 63 is engaged with the ring groove. 614, the locking ring 61 is positioned in a non-locking position, but the torque wrench structure is displaced to the part being rotated when rotating, and the locking ring 61 is easy to knock when the torque wrench structure is displaced. To other objects, when the lock ring 61 is bumped, the force of the bump is the direction of the lock ring 61 toward the adjustment handle 30, that is, when the lock ring 61 is bumped, the lock will make the lock The fixing ring 61 is automatically shifted to the non-locking position, and the adjusting grip 30 of the torque wrench structure can have a function of adjusting torque without safety.
2、該定位珠65係不受該抵推面612頂推而相對應於該斜面616,使該定位珠65可活動於該容置槽611與該定位槽13間,該調整握把30即可相對該主桿體10旋動,但當該調整握把30相對該主桿體10旋動以調整扭力值時,該調整握把30旋轉時係無設有任何可發出旋轉時之提示聲,以供了解該扭力扳手目前之扭力值狀態,操控上係不具便利性。 2. The positioning bead 65 is not pushed by the abutting surface 612 and corresponds to the inclined surface 616, so that the positioning bead 65 can move between the receiving groove 611 and the positioning groove 13, and the adjusting grip 30 is Can be rotated relative to the main lever body 10, but when the adjustment grip 30 is rotated relative to the main lever body 10 to adjust the torque value, the adjustment grip 30 is not provided with any prompt sound when rotating To understand the current state of the torque value of the torque wrench, it is not convenient to control the system.
3、該定位槽13係隱於該調整握把30內,該調整握把30旋轉時,該定位珠65可能還未對正其一定位槽13時,位移該鎖固環61即無法使該定位珠65容設於該定位槽13內,該鎖固環61亦無法回位至鎖固位置,操作時即會不便利。 3. The positioning groove 13 is hidden in the adjusting handle 30. When the adjusting handle 30 rotates, the positioning bead 65 may not be aligned with one of the positioning grooves 13. Displacement of the locking ring 61 cannot make the The positioning beads 65 are accommodated in the positioning groove 13, and the locking ring 61 cannot be returned to the locked position, which is inconvenient during operation.
有鑑於上述習用結構之缺失,本發明人藉多年從事相關行業之製造、生產及設計經驗,終於有一能解決習用弊端之扭力扳手結構之產品問世。 In view of the lack of the conventional structure mentioned above, the inventor has, through years of experience in manufacturing, production, and design in related industries, finally came up with a product that can solve the disadvantages of the conventional torque wrench structure.
發明所欲解決之問題:習用扭力扳手結構中,該扭力扳手結構位移時,該鎖固環係易踫撞至其它物體,踫撞之力量係為該鎖固環往該 調整握把之方向而自動移位至非鎖固位置處,不具有安全性。本發明之扭力扳手結構之該扭力扳手結構在操作時,該控制套環受踫撞時,該控制套環係受往該驅動部反方向之力,該驅動部反方向之力係無法使該控制套環移動到非鎖固位置,該控制套環係往該驅動部方向推移之動作係較具有安全性。 The problem to be solved by the invention: In the conventional torque wrench structure, when the torque wrench structure is displaced, the locking ring is easy to bump into other objects, and the force of the collision is the locking ring to the Adjusting the direction of the grip and automatically shifting it to the non-locking position is not safe. In the torque wrench structure of the present invention, when the torque wrench structure is in operation, when the control collar is bumped, the control collar is subjected to a force in the opposite direction to the driving part, and the force in the opposite direction to the driving part cannot make the The control collar moves to the non-locking position, and the movement of the control collar toward the driving part is more secure.
解決問題之技術手段:本發明係關於一種扭力扳手結構,其係包括:一第一本體係設有一容置槽、一第一穿槽及一第一環槽;一第二本體係設有一驅動部及複數定位槽;一控制套環係依序設有該第一周面、該第一錐形槽、該第二周面及第二錐形槽;一第一環體係套設於該第一本體之該第一環槽處,該第一環體係隱於該控制套環內,該第一環體係略具外張彈性;一定位件係容設於該第一穿槽處,該定位件係隱於該控制套環內。 Technical means for solving the problem: The present invention relates to a torque wrench structure, which includes: a first system is provided with a receiving groove, a first through groove and a first ring groove; a second system is provided with a drive And a plurality of positioning grooves; a control collar is sequentially provided with the first peripheral surface, the first tapered groove, the second peripheral surface, and the second tapered groove; a first ring system is sleeved on the first At the first ring groove of a body, the first ring system is hidden inside the control collar, and the first ring system is slightly outwardly elastic; a positioning member is accommodated at the first through groove, and the positioning The pieces are hidden inside the control collar.
對照先前技術之功效:該控制套環係於該第一本體上往該驅動部之方向移動至非鎖固位置,亦即該控制套環係往該驅動部方向推移,該扭力扳手結構在操作時,該扭力扳手結構係使該驅動部往工件方向移位,在移位時有時會使該控制套環踫撞至其它物,該控制套環受踫撞時,該控制套環係受往驅動部反方向之力,該驅動部反方向之力係無法使該控制套環移動到非鎖固位置,該控制套環係往該驅動部方向推移係較具有安全性。該控制套環於該第一本體上往該驅動部之方向移動至非鎖固位置時,該彈性元件係受該第一抵緣壓抵而呈壓縮狀,該第一環體係外張而頂抵於該第二錐形槽處,使該控制套環即定位於非鎖固位置上,該手即不需一直推抵該控制套環。該第一環體外張而頂抵該第二錐形槽處時,該第一 環體外張會具有聲音,亦可依其該第一環體已發聲而確定控制套環係於非鎖固位置。 Contrast the effect of the prior art: the control collar is moved to the unlocking position on the first body toward the driving part, that is, the control collar is moved toward the driving part, and the torque wrench structure is operating At this time, the torque wrench structure shifts the driving part toward the workpiece, and sometimes causes the control collar to bump into other objects during the shift. When the control collar is bumped, the control collar is subject to The force in the opposite direction to the driving part cannot force the control collar to move to the unlocked position, and it is safer to move the control collar toward the driving part. When the control collar is moved to the non-locking position on the first body toward the driving portion, the elastic element is compressed by the first abutment edge, and the first ring system is stretched outward and top.
