Description
本創作係有關於一種棘輪扳手,特別係指一種換向式棘輪扳手。This creation is about a ratchet wrench, especially a reversing ratchet wrench.
如圖1所示,係為一種習知棘輪扳手之嚙合狀態示意圖,其主要包括一本體100,其具有一頭部101,頭部101具有一第一容置槽102及一第二容置槽103呈相通狀,一棘輪104轉動設置於第一容置槽102,二制齒105容置於第二容置槽103,制齒105一端樞設於第二容置槽103之內壁,二彈性體106一端係抵於第二容置槽103之側壁面上,另端係抵於制齒105上,以使制齒105嚙合於棘輪104,一控制桿107係樞設於第二容置槽103,控制桿107旋動時並推抵一制齒105,使其制齒105相對棘輪104脫開。As shown in FIG. 1 , it is a schematic view of a meshing state of a conventional ratchet wrench, which mainly includes a body 100 having a head 101 having a first receiving groove 102 and a second receiving groove. 103 is in the same state, a ratchet wheel 104 is rotatably disposed in the first accommodating groove 102, and the second toothing 105 is received in the second accommodating groove 103, and one end of the toothing 105 is pivotally disposed on the inner wall of the second accommodating groove 103, One end of the elastic body 106 is abutted against the side wall surface of the second accommodating groove 103, and the other end is fastened to the tooth forming 105 so that the toothing 105 is engaged with the ratchet wheel 104, and a control rod 107 is pivoted to the second accommodating portion. In the groove 103, when the lever 107 is rotated, it pushes against a tooth 105, so that the tooth 105 is disengaged from the ratchet 104.
前述棘輪扳手之二制齒105分別受二彈性體106抵頂,於控制桿107換向轉動時, 控制桿107推抵其一制齒105,使其偏壓其一彈性體106,而使該制齒105與棘輪104脫開,而另一制齒105僅受另一彈性體106之頂持,而使其與棘輪104嚙合,如此該制齒105無法達到有效嚙合於棘輪104之狀態,其嚙合程度不足,時常造成使用者必需要再調動控制桿107,才能夠使制齒105完全嚙合於棘輪104,以致使用上較為不便;再者,如果制齒105尚未完全嚙合於棘輪104時,操作者在施力操作上,容易發生齒與齒之間的打滑情形,而無法明確施力於扳動作業,於此長期下,制齒105與棘輪104則存在著崩壞之潛藏性風險,如果在施力過程中,制齒105或棘輪104之齒一旦崩壞,更易使得施力之瞬間失去頂掣支點,導致突然性的打滑,可能影響操作者之作業安全。The two teeth 105 of the ratchet wrench are respectively abutted by the two elastic bodies 106. When the control rod 107 is rotated in the reverse direction, the control rod 107 is pushed against one of the teeth 105 to bias the elastic body 106 thereof. The tooth 105 is disengaged from the ratchet 104, and the other tooth 105 is only held by the other elastic body 106 to engage the ratchet 104, so that the tooth 105 cannot be effectively engaged with the ratchet 104. Insufficient degree of meshing often causes the user to need to mobilize the lever 107 again to enable the toothing 105 to fully engage the ratchet 104, so that it is less inconvenient to use; further, if the toothing 105 is not fully engaged with the ratchet 104, the operation is performed. In the force-applying operation, the slippage between the teeth and the teeth is prone to occur, and the force application to the pulling operation cannot be clearly determined. In this long-term, the teeth 105 and the ratchet 104 have the potential to collapse, if During the force application process, once the teeth of the tooth 105 or the ratchet 104 collapse, it is easier to lose the top fulcrum at the moment of the force application, resulting in sudden slippage, which may affect the safety of the operator.
同時,習知棘輪扳手之結構尚為繁雜,組裝亦為不便,並且需使用兩類似壓縮彈簧型態之彈性體106,加上彈簧能力受到空間之限制,而造成使用壽命不長,影響換向與嚙合之效果,另外,兩彈性體106如無法有效固定於第二容置槽103之內壁,則可能影響棘輪扳手實質使用效果,嚴重者可能形成卡死狀,如此,習知棘輪扳手確實有相當大之改進空間。At the same time, the structure of the conventional ratchet wrench is still complicated, and the assembly is also inconvenient, and two elastic bodies 106 similar to the compression spring type are required, and the spring capacity is limited by the space, so that the service life is not long, and the reversal is affected. In addition, if the two elastic bodies 106 cannot be effectively fixed to the inner wall of the second accommodating groove 103, the effect of the ratchet wrench may be affected, and the serious result may be stuck. Thus, the conventional ratchet wrench does. There is considerable room for improvement.

The reversing member 40 is positioned, and a spring washer 90 is disposed between the card slot 17 and the cover 60 for the cover 60 to be fastened to the card slot 17 without being loosened.
請參閱圖5所示,係為本創作之換向件位於第一位置,顯示兩棘齒塊未嚙合於棘輪之示意圖。由於換向件40位於第一位置(即尚未偏轉之狀態),換向件40之抵靠邊面423之兩側恰抵持於兩棘齒塊30,並迫使彈性件50之第一頂推部53、第二頂推部54相對遠離,而使安裝部51形成外張狀態,俾使兩棘齒塊30呈現張開狀,其齒部31無法嚙合於棘輪20之棘齒21,如此,棘輪扳手相對頭部11為空轉,其中藉由第一邊面421、第二邊面422分別與抵靠邊面423之間為銳角狀,於抵持狀態時,可迫使兩棘齒塊30有效定位,而不易偏位。Referring to FIG. 5, the reversing member of the present invention is located at the first position, and the two ratchet blocks are not meshed with the ratchet. Since the reversing member 40 is in the first position (ie, the state has not been deflected), the two sides of the abutting side surface 423 of the reversing member 40 abut against the two ratchet blocks 30, and the first pushing portion of the elastic member 50 is forced. 53. The second pushing portion 54 is relatively far away, and the mounting portion 51 is formed in an outer tension state, so that the two ratchet blocks 30 are opened, and the tooth portion 31 cannot be engaged with the ratchet teeth 21 of the ratchet wheel 20, so that the ratchet wrench is opposite The head 11 is idling, wherein the first side surface 421 and the second side surface 422 are respectively acutely angled with the abutting side surface 423. When the state is resisted, the two ratchet blocks 30 can be forced to be effectively positioned, which is not easy. Offset.
繼續參閱圖6所示,係為本發明之換向件位於第二位置,顯示棘輪能相對頭部逆時針旋轉之示意圖。當以順時針方向撥轉換向件40至第二位置,於其撥轉過程中,換向件40之抵靠邊面423抵接圖式左側之棘齒塊30位置,恰由抵靠邊面423之側邊位置逐漸移動至中央位置,持續止擋棘齒塊30,以保持棘齒塊30相對棘輪20為脫開,同時,由於換向件40在撥轉中,圖式右側之棘齒塊30因不再受到抵靠邊面423之壓迫,此時安裝部51由外張狀態改逐漸變化成內縮狀態,而釋放出蓄存之彈力,使第二頂推部54藉彈力而頂推棘齒塊30,並使其朝左擺動,以使其棘齒塊30嚙合於棘輪20,並且由於換向件40之第二邊面422恰抵接於該棘齒塊30內側面,有助於棘齒塊30受第二頂推部54之抵頂,而使其齒部31有效嚙合於棘輪20之棘齒21,避免發生嚙合不確實之齒與齒的打滑情形,就此棘輪20僅能逆時針方向轉動,換言之,棘齒扳手能夠順時針驅動套筒。Continuing to refer to FIG. 6, the reversing member of the present invention is in the second position, and the ratchet can be rotated counterclockwise with respect to the head. When the shifting member 40 is turned to the second position in the clockwise direction, the abutting side surface 423 of the reversing member 40 abuts the position of the ratchet block 30 on the left side of the drawing, just as it abuts against the side surface 423. The side position gradually moves to the center position, and the ratchet block 30 is continuously stopped to keep the ratchet block 30 disengaged from the ratchet 20, and at the same time, since the reversing member 40 is in the dialing, the ratchet block 30 on the right side of the drawing Since the pressing portion 423 is no longer pressed against the side surface 423, the mounting portion 51 is gradually changed from the outer tension state to the retracted state, and the stored elastic force is released, so that the second pushing portion 54 pushes the ratchet by the elastic force. The block 30 is swayed to the left so that the ratchet block 30 is engaged with the ratchet 20, and since the second side surface 422 of the reversing member 40 abuts against the inner side of the ratchet block 30, the spine is facilitated. The tooth block 30 is abutted by the second pushing portion 54, and the tooth portion 31 is effectively engaged with the ratchet teeth 21 of the ratchet wheel 20, so as to avoid the occurrence of the slipping of the teeth and the teeth which are not engaged, so that the ratchet wheel 20 can only counterclockwise. The direction is rotated, in other words, the ratchet wrench can drive the sleeve clockwise.
再者,安裝部51之彈力釋放為扭力型態,在有限地空間下,相較於習知結構具有較佳之彈力釋放效果,有助於換向與齒嚙合,同時可提高使用之壽命,加上本創作僅採單一彈性件50即可達到換向之效果,不但簡化了結構、亦使組裝更為快速便利,同時彈性件50定位於換向件40,其定位明確,無需於第二容置槽14內設置其他任何定位構造,可免除習知結構彈簧定位不佳而有卡死棘輪之情形。Furthermore, the elastic force of the mounting portion 51 is released into a torsional type, and in a limited space, the elastic releasing effect is better than that of the conventional structure, which facilitates the commutation and tooth engagement, and at the same time improves the service life. In the present invention, only a single elastic member 50 can achieve the effect of reversing, which not only simplifies the structure, but also makes the assembly quicker and more convenient. At the same time, the elastic member 50 is positioned on the reversing member 40, and the positioning thereof is clear, and the second capacity is not needed. Any other positioning structure is provided in the slot 14 to avoid the situation that the conventional structure spring is not well positioned and the ratchet is stuck.
請參閱圖7所示,係為本發明之換向件位於第三位置,顯示棘輪能相對頭部順時針旋轉之示意圖。如前述,同理可證地,操作者可逆時針方向撥轉換向件40至第三位置,使換向件40之抵靠邊面423抵接於圖式右側之棘齒塊30,使棘齒塊30相對棘輪20為脫開,而第一頂推部53則藉彈力頂推棘齒塊30,以及棘齒塊30之內側面受到換向件40之第一邊面421抵接,使其齒部31有效嚙合於棘輪20之棘齒21,如此棘輪20僅能順時針方向轉動,換言之,棘齒扳手能夠逆時針驅動套筒。Please refer to FIG. 7 , which is a schematic diagram of the reversing member of the present invention in a third position, showing that the ratchet can rotate clockwise relative to the head. As described above, it is convincing that the operator can reverse the direction of the shifting member 40 to the third position, so that the abutting side surface 423 of the reversing member 40 abuts against the ratchet block 30 on the right side of the drawing, so that the ratchet block The relative ratchet 20 is disengaged, and the first pushing portion 53 pushes the ratchet block 30 by the elastic force, and the inner side surface of the ratchet block 30 is abutted by the first side surface 421 of the reversing member 40 to make the tooth The portion 31 is effectively engaged with the ratchet 21 of the ratchet 20 such that the ratchet 20 can only rotate in a clockwise direction, in other words, the ratchet wrench can drive the sleeve counterclockwise.
參閱圖8所示,係為本創作之另一較佳實施例,顯示棘齒塊、換向件與彈性件之放大示意圖。於本實施例中,兩棘齒塊30之側邊分別設有定位槽32,以利於第一頂推部53與第二頂推部54容置,藉以在換向動作中具有較佳之定位效果,而使第一頂推部53與第二頂推部54不易相對棘齒塊30側邊打滑。Referring to FIG. 8, which is another preferred embodiment of the present invention, an enlarged schematic view of the ratchet block, the reversing member and the elastic member is shown. In the embodiment, the side edges of the two ratchet blocks 30 are respectively provided with positioning slots 32 for facilitating the first pushing portion 53 and the second pushing portion 54 for better positioning effect in the reversing action. Therefore, the first pushing portion 53 and the second pushing portion 54 are less likely to slip against the side of the ratchet block 30.
綜合上述,本創作係利用單一彈性件,於換向中選擇性地頂推其一棘齒塊,使其棘齒塊嚙合於棘輪,具有結構簡單,組裝便利之功效。In summary, the present invention utilizes a single elastic member to selectively push a ratchet block in the reversing direction to engage the ratchet block with the ratchet wheel, and has the advantages of simple structure and convenient assembly.
而本創作之彈性件係為一扭力彈簧,其在有限地空間環境下,相較於習知棘輪扳手之彈簧,具有較佳之扭力釋放,如此可助於換向與齒嚙合之確實性,同時可延長使用壽命。The elastic member of the present invention is a torsion spring, which has a better torque release in a limited space environment than a spring of a conventional ratchet wrench, which can help the reversal and the tooth meshing accuracy, and at the same time Can extend the life.
