Abstract

A torque wrench structure includes a tube body, a drive member, a torque adjustment member adjusting the torque outputted by the drive member driving the workpiece, and a block member. The drive member has a shaft extending from one end of the tube body in the cavity thereof, with one end of the shaft adjacent to the drive member and pivotally combined with the tube body through a pivot member. The shaft includes a through hole, and the block member is fixed in the tube body passing through the through hole. The gap of the block member passing therethough is smaller than the gap between the shaft with respect to the inner wall in the cavity. Thus, when the shaft pivots in the cavity to be bent, two ends of the through hole abut against the block member, preventing the shaft from contacting the inner wall.

Description

扭力扳手結構Torque Wrench Structure

本發明係關於一種扭力扳手結構，尤指一種可調整扭力以驅動工件之扭力扳手結構。The present invention relates to a torque wrench structure, especially a torque wrench structure that can adjust the torque to drive a workpiece.

習知扭力扳手結構，主要包括管體、驅動件及扭力調整件，驅動件有一長柄樞接於管體且伸設於其中，扭力調整件則於管體的一端置於管體內且推抵在長柄的一端，藉由扭力調整件調整所述推抵的力量以決定驅動頭可對工件驅動之最大扭力，待所述最大扭力達到時，長柄隨驅動頭受力大於扭力調整件推抵之力量而於管體內樞擺，此時長柄的端部在其樞擺瞬間會敲擊管體內壁，操作者便會感到長柄樞擺時錯位的手感來警示扭力已達，讓操作者得知可停止對工件之驅動。The conventional torque wrench structure mainly includes a tube body, a driving member and a torque adjusting member. The driving member has a long handle pivotally connected to the tube body and extending therein. At one end of the long handle, the pushing force is adjusted by the torsion adjustment piece to determine the maximum torque that the drive head can drive the workpiece. When the maximum torque is reached, the force of the long handle along with the driving head is greater than the pushing force of the torque adjustment piece. When the tube is pivoted, the end of the long handle will hit the inner wall of the tube at the moment of its pivoting, and the operator will feel the dislocation of the long handle when it is pivoted to warn that the torque has reached and let the operator know that it can stop. Drive the workpiece.

然而，習知扭力扳手結構在扭力已達而發出警示時，長柄的端部在其樞擺瞬間對管體內壁之敲擊，必然會對管體內壁造成損傷，例如管體內壁係經電鍍或染黑等防鏽處理，管體內壁受敲擊之部位久而久之將受破壞而開始鏽蝕，最後將導致扭力扳手結構無法再使用而報銷。因此，如何解決上述之問題，即為本發明之主要重點所在。However, when the conventional torque wrench structure issues a warning when the torque has reached, the end of the long handle strikes the inner wall of the tube at the moment of its pivoting, which will inevitably cause damage to the inner wall of the tube. For example, the inner wall of the tube is electroplated or With anti-rust treatment such as blackening, the parts of the inner wall of the tube that are knocked will be damaged and begin to rust over time, and eventually the torque wrench structure will be unusable and will be reimbursed. Therefore, how to solve the above problems is the main focus of the present invention.

為解決上述課題，本發明提供一種扭力扳手結構，其可於設定之扭力已達時發出警示，且能避免管體在發出警示時受敲擊而損壞。In order to solve the above problems, the present invention provides a torque wrench structure, which can issue a warning when the set torque has reached, and can prevent the pipe body from being knocked and damaged when the warning is issued.

上述實施例之扭力扳手結構於實際操作時，係以驅動件20套接有驅動用之套筒A(於此係以內六角套筒為例)，並將套筒A套設在一工件B(於此係以外六角螺栓為例)，藉由操作者手持管體10之一端往旋緊方向旋動(如圖3所示)，直至達到扭力調整件30所調整驅動件20對工件驅動時輸出之扭力，以致長柄21在腔室11中依第一軸向X樞擺(如圖4所示)而產生歪斜，滑動塊33此時則隨第一溝部24和第二溝部311錯位而滑移，直至穿孔23之兩端緣232卡止於阻擋軸件40(如圖5所示)，第二端212因此受限制而不觸及管體10之內壁12，此時操作者便會感到長柄21樞擺時錯位的手感，藉此，操作者便可獲得扭力已達之警示以停止對工件之驅動，甚或在穿孔23之兩端緣232卡止於阻擋軸件40所發出之聲響，以輔助操作者獲知扭力已達之警示效果。In the actual operation of the torque wrench structure of the above-mentioned embodiment, the driving member 20 is sleeved with a driving sleeve A (here, an inner hexagonal sleeve is used as an example), and the sleeve A is sleeved on a workpiece B ( Take the outer hexagon bolt as an example), the operator holds one end of the pipe body 10 and rotates it in the tightening direction (as shown in FIG. 3 ), until the output when the driving element 20 adjusted by the torque adjusting element 30 drives the workpiece is reached Therefore, the long handle 21 pivots in the chamber 11 according to the first axis X (as shown in FIG. 4 ) to produce skew, and the sliding block 33 slides along with the dislocation of the first groove portion 24 and the second groove portion 311 at this time. , until the two end edges 232 of the through hole 23 are locked on the blocking shaft member 40 (as shown in FIG. 5 ), the second end 212 is thus restricted and does not touch the inner wall 12 of the tube body 10 , and the operator will feel the long handle 21 has a dislocated feel when pivoting, whereby the operator can get a warning that the torque has reached to stop driving the workpiece, or even the sound emitted by the blocking shaft 40 when the two end edges 232 of the through hole 23 are locked to prevent Assist the operator to know the warning effect that the torque has reached.

由上述之說明不難發現本發明之特點在於，當以驅動件20對工件B驅動時，當扭力調整件30所設定之扭力已達，長柄21便在腔室11中樞擺至歪斜，以產生錯位的手感來警示扭力已達，此時是以穿孔23之兩端緣232卡止於阻擋軸件40，意即長柄21之第二端212在觸及管體10之內壁12前即已停止，藉此讓長柄21之第二端212不觸及管體10之內壁12，管體10之內壁12便不會有受長柄21之第二端212不斷敲擊而導致管體10之內壁12有受損的情況，相較於習知扭力扳手結構發出警示之方式，本發明可避免扭力扳手結構因管體10之內壁12受損而無法使用之問題發生，以達成扭力扳手結構之使用壽命相對長之功效。From the above description, it is not difficult to find that the present invention is characterized in that, when the workpiece B is driven by the driving member 20, when the torque set by the torque adjusting member 30 has reached, the long handle 21 pivots in the center of the chamber 11 to skew, so as to generate The misaligned hand feels to warn that the torque has reached. At this time, the two end edges 232 of the through hole 23 are locked to the blocking shaft member 40, which means that the second end 212 of the long handle 21 stops before touching the inner wall 12 of the tube body 10. , so that the second end 212 of the long handle 21 does not touch the inner wall 12 of the pipe body 10 , and the inner wall 12 of the pipe body 10 will not be continuously knocked by the second end 212 of the long handle 21 and cause the inner wall of the pipe body 10 When the wall 12 is damaged, compared with the conventional torque wrench structure to issue a warning, the present invention can avoid the problem that the torque wrench structure cannot be used due to damage to the inner wall 12 of the tube body 10, so as to achieve the torque wrench structure The effect of relatively long service life.
