Description
本發明係與一種棘輪扳手結構有關，特別是指一種可提升棘齒定位效果之棘輪扳手結構。 The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure capable of improving the ratchet positioning effect.
按，請參閱第1圖所示，其係為我國專利公告號第414120號新型專利案所揭露之棘輪扳手，該棘輪扳手係藉由棘齒塊1頂掣於容置槽4之內壁面上，而使棘齒塊1與棘齒環2間相互卡制嚙合，惟，由於該棘齒塊1僅於一側受到彈性體3抵頂，因此該棘齒塊1之背部係呈懸空狀而無任何支撐點，故當該棘齒塊1受力達一定值時，其懸空之背部不受抵制，故不會產生任何反作用力，該棘齒塊1便會以其一側之支撐點為支點作偏擺而使該棘齒塊1另端之棘齒略為脫離嚙合而產生翹翹板效應，此一翹翹板效應將造成該棘齒塊1僅由前少數棘齒嚙合受力，而致使該棘齒塊1之棘齒易致崩裂，導致該棘輪扳手極容易損壞。 According to FIG. 1 , it is a ratchet wrench disclosed in the new patent application No. 414120, which is mounted on the inner wall surface of the accommodating groove 4 by the ratchet block 1 . And the ratchet block 1 and the ratchet ring 2 are engaged with each other, but since the ratchet block 1 is only abutted on the one side by the elastic body 3, the back of the ratchet block 1 is suspended. There is no support point, so when the ratchet block 1 is subjected to a certain force, the suspended back is not resisted, so no reaction force is generated, and the ratchet block 1 has the support point on one side thereof. The fulcrum is yawed so that the ratchet of the other end of the ratchet block 1 is slightly disengaged to produce a seesaw effect, and the seesaw effect will cause the ratchet block 1 to be stressed by only a few ratchet teeth. The ratchet of the ratchet block 1 is liable to cause cracking, resulting in the ratchet wrench being extremely vulnerable to damage.
有鑑於此，坊間出現一種具雙剛性支點之棘輪扳手，請參閱第2圖所示，其係為我國專利公告號第I235696號發明專利案所揭露之棘輪扳手，該棘輪扳手之棘齒塊1係藉由彈性體3之彈力而使棘齒塊1一端之弧面頂制於容置槽4之內壁面上，且該棘齒塊1之另端係受頂掣件5頂掣於凹部6之頂面，俾使該棘齒塊1之兩端係皆分別受到剛性支點之頂掣，而使棘齒塊1之棘齒於扳動時乃密合於棘齒環2之棘齒，則受力自會平均的落在受力齒面上的每一齒，而不會如習知棘齒塊受力集中於少數棘齒，而是所有棘齒皆呈咬合狀態，亦即每一棘齒皆受力，藉此達到受力分散之目的，不僅使確實嚙合的棘齒數較習知棘齒塊的實際受力棘齒數多，且每一棘齒的咬合受力更穩固確實，俾使該棘輪扳手可承受更高之扭力值。 In view of this, there is a ratchet wrench with a double rigid fulcrum, as shown in Fig. 2, which is a ratchet wrench disclosed in the invention patent No. I235696, the ratchet wrench of the ratchet wrench 1 The arc surface of one end of the ratchet block 1 is topped on the inner wall surface of the accommodating groove 4 by the elastic force of the elastic body 3, and the other end of the ratchet block 1 is received by the top cymbal member 5 against the concave portion 6. The top surface of the ratchet block 1 is respectively subjected to the top of the rigid fulcrum, and the ratchet of the ratchet block 1 is tightly attached to the ratchet of the ratchet ring 2 when the ratchet block 1 is pulled. The force will gradually fall on each tooth on the surface of the force tooth, and it will not concentrate on a few ratchets as the conventional ratchet block, but all the ratchets will be in a occlusal state, that is, each spine The teeth are all stressed, thereby achieving the purpose of force dispersion, not only making the number of ratchets that are actually engaged more than the actual number of ratchets of the conventional ratchet block, and the bite force of each ratchet is more stable and firm. This ratchet wrench can withstand higher torque values.
然而，雖該棘輪扳手之棘齒塊1可藉該彈性體3之抵頂，而 使該棘齒塊1一端頂制於容置槽4之內壁面上，另端則恰可受該頂掣件5頂掣，俾形成該棘齒塊1左右兩端之剛性支點，惟，該彈性體3係僅抵頂於該棘齒塊1之上側，而有使該棘齒塊1上下受力不平均之虞，故當該棘齒塊1受力達一定值時，其未受頂掣而無任何支撐點之下側，係有脫離嚙合之虞，而難以確實與該棘齒環2嚙合，是具有與我國專利公告號第503803號新型專利案所揭露之棘輪扳手相同之缺點。 However, although the ratchet block 1 of the ratchet wrench can be abutted by the elastic body 3, One end of the ratchet block 1 is topped on the inner wall surface of the accommodating groove 4, and the other end is just received by the top cymbal member 5, and the fulcrum of the left and right ends of the ratchet block 1 is formed. The elastic body 3 only abuts against the upper side of the ratchet block 1 and has an unevenness of the upper and lower forces of the ratchet block 1. Therefore, when the ratchet block 1 is subjected to a certain force, it is not topped. The lower side of the support point without any support point is the same as the ratchet wrench disclosed in the new patent application No. 503803 of the Chinese Patent Publication No. 503803.
請參閱第3圖至第5圖所示，其係為我國專利公告號第 503803號新型專利案所揭露之棘輪扳手，該棘輪扳手係利用彈性體3頂推接觸棘齒塊1，使該棘齒塊1能夠藉以嚙合在棘齒環2外周圍，然而，由於該棘齒塊1僅於一側受到抵頂，因此該棘齒塊1之另側係呈懸空狀而無任何支撐點，故當該棘齒塊1受力達一定值時，其懸空該側係不受抵制，而不會產生任何反作用力，以致該棘齒塊1係以其一側之支撐點為支點作偏擺，使該棘齒塊1另端之棘齒略為脫離嚙合而產生翹翹板效應，此一翹翹板效應將造成該棘齒塊1之棘齒支撐受力不平均，致使該等棘齒嚙合受力時極易致崩裂，進而導致該棘輪扳手容易損壞且扭力不足。 Please refer to Figures 3 to 5, which is the China Patent Announcement No. The ratchet wrench disclosed in the new patent No. 503803, which uses the elastic body 3 to push the ratchet block 1 so that the ratchet block 1 can be engaged around the ratchet ring 2, however, due to the ratchet The block 1 is only abutted on one side, so that the other side of the ratchet block 1 is suspended without any support point, so when the ratchet block 1 is subjected to a certain force, the side is not suspended. Resist, without any reaction force, so that the ratchet block 1 is yawed with the support point on one side as a fulcrum, so that the ratchet of the other end of the ratchet block 1 is slightly disengaged to produce a see-saw effect. The seesaw effect will cause the ratchet support of the ratchet block 1 to be unevenly stressed, so that the ratchet teeth are easily broken when the meshing force is applied, thereby causing the ratchet wrench to be easily damaged and the torque is insufficient.
有鑑於此，坊間出現另一種棘輪扳手，請參閱第6圖所示， 其係為我國專利公告號第I350231號發明專利案所揭露之棘輪扳手，該棘輪扳手係於控制件7朝向棘齒塊1的一側開設有兩個限位槽8，並於該等限位槽8各容置有一彈性體3，且該等限位槽8係上下排列於該控制件7，俾使該等彈性體3可分別的頂推於棘齒塊1的上方位置與下方位置，藉此，可使棘齒塊1的上方與下方同時嚙合於棘齒環2，並於實際使用時，若是於棘齒塊1與棘齒環2之間有油污阻礙而影響其嚙合狀態，該等彈性體3可克服阻礙，使棘齒塊1的上方與下方同時嚙合於棘齒環2，避免產生翹翹板效應而造成局部嚙合的缺點。 In view of this, another ratchet wrench appears in the workshop, as shown in Figure 6. It is a ratchet wrench disclosed in the patent application No. I350231 of the invention. The ratchet wrench is provided with two limiting slots 8 on the side of the control member 7 facing the ratchet block 1 and is at the limit. Each of the slots 8 is provided with an elastic body 3, and the limiting slots 8 are arranged up and down on the control member 7 so that the elastic bodies 3 can be respectively pushed up and below the ratchet block 1 . Thereby, the upper and lower sides of the ratchet block 1 can be simultaneously engaged with the ratchet ring 2, and in actual use, if there is oil stain between the ratchet block 1 and the ratchet ring 2, the meshing state is affected. The elastic body 3 can overcome the obstruction, and simultaneously engage the upper and lower sides of the ratchet block 1 with the ratchet ring 2, thereby avoiding the disadvantage of causing the seepage effect and causing local meshing.
惟，該棘輪扳手所加工的各個孔、槽等空間，其彼此之間的 垂直度或平行度係難以控制在極精密的公差內，因此係將導致該棘輪扳手的精密加工造成成本過高，並嚴重影響生產速度，而致使產能大幅降低。 若該棘輪扳手所加工的各個孔、槽之間的垂直度或平行度在一般的公差範圍內時，則將產生棘齒塊1與棘齒環2嚙合度不佳或無法完全嚙合的情況，以致造成應力集中而出現崩齒的問題，有鑑於此，本案發明人在觀察到上述缺點後，認為習知棘輪扳手實有進一步再改良之必要，而遂有本發明之產生。 However, the space, the groove, and the like processed by the ratchet wrench are between each other The degree of verticality or parallelism is difficult to control within extremely tight tolerances, so the precision machining of the ratchet wrench will result in excessive cost and severely affect the production speed, resulting in a significant reduction in production capacity. If the verticality or parallelism between the holes and the grooves processed by the ratchet wrench is within a normal tolerance range, the ratchet block 1 and the ratchet ring 2 may be in poor meshing or incomplete meshing. In view of the above-mentioned shortcomings, the inventors of the present invention have found that the conventional ratchet wrench has been further improved, and the present invention has been produced.
本發明之目的係在提供一種可提升棘齒定位效果之棘輪扳手結構，其係可避免棘齒塊與棘齒環局部嚙合而導致崩齒，並克服習知棘輪扳手利用多個彈性定位元件頂推棘齒塊所產生之平行度或垂直度不佳的公差問題，從而提升棘齒定位效果與嚙合穩定性。 The object of the present invention is to provide a ratchet wrench structure capable of improving the ratcheting positioning effect, which can avoid the partial engagement of the ratchet block and the ratchet ring to cause the chipping, and overcome the conventional ratchet wrench using a plurality of elastic positioning elements.

為供進一步瞭解本發明構造特徵、運用技術手段及所預期達 成之功效，茲將本發明使用方式加以敘述，相信當可由此而對本發明有更深入且具體之瞭解，如下所述：請繼續參閱第12圖所示，並請配合參閱第8圖及第9圖所示，當使用者在進行旋緊工作物的作業時，該棘輪扳手係透過該抵頂銷45 縱向抵頂該棘齒塊30之抵接面32，使該棘齒塊30與該棘齒環20嚙合，並相對該扳手本體10轉動，而使該棘齒塊30之第一抵頂面341抵頂該第一抵制面151，此時由於該第一抵頂面341係與該第一抵制面151緊配貼合，故可形成一大面積之剛性支撐面，然再進一步透過該抵頂銷45縱向抵頂該棘齒塊30之抵接面32，俾使該抵頂銷45可大面積的施力抵頂該棘齒塊30，以令該抵頂銷45能夠同時頂推該棘齒塊30的上方位置、中間位置與下方位置，俾使該棘齒塊30於扳動時乃可完全緊密嚙合該棘齒環20，而讓受力平均落在受力齒面上的每一齒，並使每一齒的咬合受力平均更穩固確實，避免脫齒而造成棘齒受力不均之情形發生，而使該棘輪扳手不僅可提升棘齒定位效果與嚙合穩定性，且可承受更高之扭力值。 For further understanding of the structural features, technical means and expectations of the present invention </ RTI> </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; As shown in FIG. 9 , the ratchet wrench passes through the ejector pin 45 when the user performs the work of tightening the work object. The abutting surface 32 of the ratchet block 30 is longitudinally abutted, and the ratchet block 30 is engaged with the ratchet ring 20 and rotated relative to the wrench body 10 to make the first abutting surface 341 of the ratchet block 30 The first resisting surface 151 is abutted against the first resisting surface 151. At this time, since the first abutting surface 341 is tightly fitted to the first resisting surface 151, a rigid supporting surface of a large area can be formed, and then the topping is further transmitted. The pin 45 longitudinally abuts against the abutting surface 32 of the ratchet block 30, so that the urging pin 45 can apply a large area of force against the ratchet block 30, so that the ejector pin 45 can simultaneously push the thorn The upper position, the middle position and the lower position of the tooth block 30 enable the ratchet block 30 to completely mesh the ratchet ring 20 when the ratchet block 30 is pulled, and the force is equally dropped on each of the force tooth surfaces. The teeth, and the occlusal force of each tooth is more stable and reliable, avoiding the occurrence of ratcheting unevenness caused by the tooth removal, and the ratchet wrench can not only improve the ratchet positioning effect and the meshing stability, but also Withstand higher torque values.
此外，由於該抵頂銷45係能夠同時頂推該棘齒塊30的上方 位置、中間位置與下方位置，因此，於使用時該棘齒塊30與該棘齒環20之間若有油污，大面積縱向抵頂該棘齒塊30之抵頂銷45係能夠克服阻礙，使該棘齒塊30的上方、中間與下方同時嚙合於該棘齒環20，而不會造成局部嚙合的缺點，且還能使該棘齒塊30與該棘齒環20之間達到高速嚙合的功能，具有提高嚙合穩定性與降低崩齒的效果。 In addition, since the ejector pin 45 can simultaneously push the top of the ratchet block 30 The position, the intermediate position and the lower position, so that if there is oil between the ratchet block 30 and the ratchet ring 20 during use, the large-area longitudinally abutting the abutting pin 45 of the ratchet block 30 can overcome the obstacle. The upper, middle and lower sides of the ratchet block 30 are simultaneously engaged with the ratchet ring 20 without causing the disadvantage of local engagement, and the high speed engagement between the ratchet block 30 and the ratchet ring 20 is also achieved. The function has the effect of improving the meshing stability and reducing the chipping.
請繼續參閱第13圖及第14圖所示，當使用者反轉該扳手本 體10時，由於該棘齒環20推開該棘齒塊30的力量係大於該矩形彈簧44彈性推抵該抵頂銷45頂推該棘齒塊30的力量，故將致使該棘齒塊30產生了後退的動作，使工作物與該棘齒環20不會跟著該扳手本體10反轉。 Please continue to refer to Figures 13 and 14 when the user reverses the wrench. In the case of the body 10, since the ratchet ring 20 pushes the ratchet block 30 more than the rectangular spring 44 elastically pushes against the force of the ratchet pin 45 pushing the ratchet block 30, the ratchet block is caused. 30 produces a retreating action that prevents the workpiece and the ratchet ring 20 from reversing against the wrench body 10.
請繼續參閱第15圖所示，並請配合參閱第8圖所示，當使 用者欲換向操作該扳手本體10時，僅需撥動該切換件46，使該抵頂銷45由抵頂該棘齒塊30之第一抵接面321轉向抵頂該棘齒塊30之第二抵接面322，藉此，即可推抵該棘齒塊30於該第二抵制面152形成一剛性支撐面，而可供使用者換向操作該扳手本體10。 Please continue to refer to Figure 15, and please refer to Figure 8 when making When the user wants to change the operation of the wrench body 10, the switch member 46 only needs to be toggled, so that the top pin 45 is turned against the top abutting surface 321 of the ratchet block 30 to abut the ratchet block 30. The second abutting surface 322 can be used to push the ratchet block 30 to form a rigid supporting surface on the second resisting surface 152, and the user can operate the wrench body 10 in a reversing manner.
由於該棘齒塊30於該第一抵接面321與該第二抵接面322 之間係設有該凸緣33，故可使該抵頂銷45於抵頂該棘齒塊30時，形成限位之效果，使該抵頂銷45明確選擇抵頂該第一抵接面321或該第二抵接面322，從而提升該抵頂銷45推抵該棘齒塊30之效果，俾使該棘齒塊30與該棘齒環20之間獲得更佳的嚙合效果。 Because the ratchet block 30 is on the first abutting surface 321 and the second abutting surface 322 The flange 33 is disposed between the flanges 33, so that the ejector pin 45 can form a limit effect when the ratchet block 30 is abutted, so that the ejector pin 45 is explicitly selected to abut the first abutment surface. 321 or the second abutting surface 322, thereby enhancing the effect of the ejector pin 45 pushing against the ratchet block 30, so as to obtain a better meshing effect between the ratchet block 30 and the ratchet ring 20.
值得一提的是，該棘輪扳手僅透過單一抵頂銷45縱向抵頂 該棘齒塊30之抵接面32，使該棘齒塊30上下同時與該棘齒環20嚙合，故可藉此克服習知棘輪扳手利用多個彈性定位元件頂推棘齒塊所產生之平行度或垂直度不佳的公差問題，並進一步降低生產成本，提高生產速度與產能，俾達經濟效益之增進。 It is worth mentioning that the ratchet wrench only longitudinally abuts through a single abutment pin 45. The abutting surface 32 of the ratchet block 30 allows the ratchet block 30 to mesh with the ratchet ring 20 at the same time, thereby overcoming the conventional ratchet wrench by pushing a plurality of elastic positioning elements to push the ratchet block. Tolerance problems with poor parallelism or verticality, and further reduce production costs, increase production speed and capacity, and increase economic benefits.
茲，再將本發明之特徵及其可達成之預期功效陳述如下：本發明之可提升棘齒定位效果之棘輪扳手結構，透過該抵頂銷縱向抵頂該棘齒塊之抵接面，不僅可增大抵頂之受力面積，俾使該棘齒塊上下可同時嚙合於該棘齒環，避免局部嚙合而造成應力集中以致發生崩齒，並進一步克服棘齒塊與棘齒環間的油污阻礙，提升棘齒定位效果與嚙合穩定性，且還能克服習知棘輪扳手利用多個彈性定位元件頂推棘齒塊所產生之平行度或垂直度不佳的公差問題。 Further, the features of the present invention and the achievable expected effects thereof are as follows: the ratchet wrench structure of the present invention for improving the ratchet positioning effect, through which the abutting pin longitudinally abuts against the abutting surface of the ratchet block, not only The force-receiving area of the top can be increased, so that the ratchet block can be simultaneously engaged with the ratchet ring at the same time, avoiding local meshing and causing stress concentration to cause chipping, and further overcoming the oil stain between the ratchet block and the ratchet ring. The obstacle is improved, the ratchet positioning effect and the meshing stability are improved, and the tolerance problem of the parallelism or the poorness of the perpendicularity generated by the conventional ratchet wrench using the plurality of elastic positioning elements to push the ratchet block can be overcome.
