Description
本新型係關於一種扳手,尤指一種換向扳手結構。 The present invention relates to a wrench, and more particularly to a reversing wrench structure.
按,習知之一種換向扳手結構,請配合參閱第9圖所示,該扳手50於一端係組裝有一旋轉件60,且該旋轉件60能於扳手50端進行旋轉,藉此扳動螺帽或螺栓進行鎖緊與旋鬆之作業,又該旋轉件60之外緣設置有一齒環61,且該齒環61一側對應齒合有一棘輪件70,而該棘輪件70能活動於扳手50內部之第一槽室51,又該棘輪件70於齒合旋轉件60之另一端面形成有一弧面71,另該扳手50於第一槽室51處相通有第二槽室52,由該第二槽室52裝設有一控制塊80,且該控制塊80開設有一插孔81,並於插孔81處裝設有一彈簧82,並於彈簧82頂端套設有一抵套83,使抵套83受彈簧82之頂推而抵觸於棘輪件70之弧面71處,藉由控制塊80控制抵套83選擇將棘輪件70頂設於第一槽室51之不同側,即能產生有單向驅動之扳動效果。 According to the conventional reversing wrench structure, as shown in FIG. 9, the wrench 50 is assembled with a rotating member 60 at one end, and the rotating member 60 can be rotated at the end of the wrench 50, thereby pulling the nut. Or the bolt is locked and unscrewed, and a toothed ring 61 is disposed on the outer edge of the rotating member 60, and a ratchet member 70 is coupled to the corresponding tooth on the side of the ring gear 61, and the ratchet member 70 can move on the wrench 50. The inner first chamber 51, the ratchet member 70 is formed with a curved surface 71 on the other end surface of the toothed rotating member 60, and the wrench 50 communicates with the second chamber 52 at the first chamber 51. The second slot chamber 52 is provided with a control block 80, and the control block 80 defines a jack 81, and a spring 82 is disposed at the jack 81, and a sleeve 83 is sleeved on the top end of the spring 82 to make the sleeve 83 is pushed by the spring 82 against the curved surface 71 of the ratchet member 70, and the control block 80 controls the abutment 83 to select the ratchet member 70 to be disposed on different sides of the first groove chamber 51, so that a single sheet can be produced. Pull the effect to the drive.
詳觀上述習知結構不難發覺其尚存有些許不足之處,主要原因係歸如下:一、該棘輪件70與控制塊80之間夾設有彈簧82與抵套83,且該抵套83一端受到彈簧82之頂推,而抵套83之另一端滑動抵壓於棘輪件70之弧面71,當棘輪件70於扳手50進行扳動而產生震動或於控制塊80進行切換時,該抵套83一端滑移於棘輪件70之弧面71,且另一端將側向磨擦於控制塊80 之插孔81,使抵套83與彈簧82容易由插孔81處彈出或產生變形,並會形成阻力而降低其操作穩定性,且明顯有結構強度不足之問題。 It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reasons are as follows: 1. The spring 82 and the abutment 83 are interposed between the ratchet member 70 and the control block 80, and the abutment is provided. One end of the 83 is pushed by the spring 82, and the other end of the sleeve 83 is slid against the curved surface 71 of the ratchet member 70. When the ratchet member 70 is pulled by the wrench 50 to generate vibration or is switched at the control block 80, One end of the abutting sleeve 83 slides on the curved surface 71 of the ratchet member 70, and the other end will be laterally rubbed on the control block 80. The jack 81 allows the abutment sleeve 83 and the spring 82 to be easily ejected or deformed by the insertion hole 81, and resistance is formed to lower the operational stability thereof, and there is a problem that the structural strength is insufficient.
二、該扳手50之組裝步驟係先將控制塊80裝設於第二槽室52處,並先進行控制塊80之扣合固定,限制控制塊80僅能進行旋轉操作,再進一步由第一槽室51端將彈簧82置入插孔81內,且於彈簧82頂端套設該抵套83,由於第一槽室51之開口朝向旋轉件60方向,將不易進行安裝彈簧82之動作,又該彈簧82與抵套83之體積較小,容易於組裝過程發生掉落或遺失之情況,更會進一步提高其組裝難度,使其有不易組裝與構件過多之缺失。 Second, the assembly step of the wrench 50 is to first install the control block 80 at the second slot chamber 52, and firstly perform the fastening and fixing of the control block 80, and the control block 80 can only perform the rotation operation, and further by the first The spring 82 is placed in the insertion hole 81 at the end of the groove chamber 51, and the abutment 83 is sleeved on the top end of the spring 82. Since the opening of the first groove chamber 51 faces the direction of the rotating member 60, the action of the mounting spring 82 is not easy to be performed. The spring 82 and the abutment 83 have a small volume, which is easy to fall or be lost during the assembly process, and further increases the difficulty of assembly, making it difficult to assemble and the lack of excess components.
三、該棘輪件70與控制塊80之間係夾設有彈簧82與抵套83,且該抵套83一端受到彈簧82之頂推,而抵套83之另一端滑動抵壓於棘輪件70之弧面71,於棘輪件70作動情況下,該抵套83能推壓彈簧82進行伸縮,因此於棘輪件70與控制塊80之間將保持有棘輪件70之活動空間,使得抵套83與彈簧82過度凸伸於插孔81外,會降低抵套83與彈簧82之定位效果。 3. The spring 82 and the abutment 83 are interposed between the ratchet member 70 and the control block 80, and one end of the abutment 83 is pushed by the spring 82, and the other end of the abutment sleeve 83 is slid against the ratchet member 70. The arc surface 71, when the ratchet member 70 is actuated, the abutment sleeve 83 can push the spring 82 to expand and contract, so that the movable space of the ratchet member 70 will be maintained between the ratchet member 70 and the control block 80, so that the sleeve 83 is provided. Excessive protrusion of the spring 82 outside the insertion hole 81 reduces the positioning effect of the abutment 83 and the spring 82.
有鑑於此,本新型人於多年從事相關產品之製造開發與設計經驗,針對上述之目標,詳加設計與審慎評估後,終得一確具實用性之本新型。 In view of this, the new model has been engaged in the manufacturing development and design experience of related products for many years.

其結構之組成,再請參閱第2、3、4圖所示,該扳手本體10係分別由該控制孔14、掣齒槽15以及裝設孔13安裝該控制件20、掣齒件30以及棘輪件40,其中,該控制件20係以軸柱22穿設於該控制孔14內,並將該柄部21限制於該限位槽141且穿出開口142外,該掣齒件30之內凹弧槽32係以一軸栓321連接一連動軸33,該連動軸33係套一彈性件34,再以該連動軸33面對控制孔14將掣齒件30通過裝設孔13置入該掣齒槽15內,同時將該連動軸33連帶該彈性件34穿設於該控制件20位於軸柱22之穿設孔23內,並透過彈性件34達到該連動軸33彈性伸縮,而該弧形齒部31則面對該裝設孔13,最後再將該棘輪件40組入該裝設孔13內,利用一C形扣件44卡掣於該限位滑槽43以及固定環槽131間,藉此將該棘輪件40限制於該裝設孔13內,俾以完成一種換向扳手結構。 The structure of the structure, as shown in FIGS. 2, 3 and 4, the wrench body 10 is respectively mounted with the control member 14, the tooth groove 15 and the mounting hole 13 for the control member 20, the tooth member 30, and The ratchet member 40, wherein the control member 20 is disposed in the control hole 14 by the shaft post 22, and the handle portion 21 is restricted to the limiting groove 141 and extends out of the opening 142. The inner concave arc groove 32 is connected to a linkage shaft 33 by a shaft bolt 321 . The linkage shaft 33 is sleeved with an elastic member 34 , and the linkage shaft 33 faces the control hole 14 to insert the tooth member 30 through the installation hole 13 . The interlocking shaft 33 is coupled to the elastic member 34 and the elastic member 34 is disposed in the through hole 23 of the shaft post 22, and the elastic shaft 34 is elastically expanded and contracted by the elastic member 34. The arc-shaped tooth portion 31 faces the mounting hole 13 , and finally the ratchet member 40 is assembled into the mounting hole 13 , and the C-shaped fastener 44 is fastened to the limiting slot 43 and the fixing ring. Between the slots 131, the ratchet member 40 is thereby restrained in the mounting hole 13 to complete a reversing wrench structure.
其結構實際使用之狀態,續請參閱第5、6圖所示,該扳手本體10係由棘輪件40之工具孔42接合螺鎖單元,並經由扳手本體10的扳轉作動達到螺鎖單元的鎖緊、鬆脫狀態,首先透過該控制件20切控該掣齒件30與該棘輪件40間之卡抵掣動方向,當掣齒件30經由該控制件20扳轉作動而抵靠於掣齒槽15之順時針方向時,同時透過該連動軸33以及彈性件34順時針方向推抵該掣齒件30,當扳手本體10順時針轉動時,由於該扳手本體10之作動方向與該彈性件34推抵方向相同,使該棘輪件40能沿著該彈性件34方向而將該掣齒件30推回,導致該掣齒件30之弧型齒部31無法有效咬合該棘輪件40之環齒部41,形成空轉狀態,反之,將該扳手本體10逆時針轉動時,請同時參閱第6圖所示,因該掣齒件30之連動軸33受彈性件34推抵方向與該扳手本體10之作動方向相反,使該掣齒件30無法被推回而將弧型齒部31確實咬合該棘輪件40之環齒部41,進而帶動該棘輪件40轉動並達到螺鎖單元的扭轉作動,藉此形成扳手本體10逆時針單向扭轉之驅動狀態。 The state in which the structure is actually used, as shown in FIGS. 5 and 6 , the wrench body 10 is engaged with the screw lock unit by the tool hole 42 of the ratchet member 40 and is actuated by the wrench body 10 to reach the screw lock unit. In the locked state, the locking member firstly controls the locking direction between the jaw member 30 and the ratchet member 40 through the control member 20, and the jaw member 30 is rotated by the control member 20 to act against When the cogging groove 15 is in the clockwise direction, the interlocking shaft 33 and the elastic member 34 are simultaneously pushed clockwise to the tooth member 30. When the wrench body 10 is rotated clockwise, the direction of movement of the wrench body 10 is The elastic member 34 is pushed in the same direction, so that the ratchet member 40 can push the tooth member 30 back along the direction of the elastic member 34, so that the arc-shaped tooth portion 31 of the tooth member 30 cannot effectively engage the ratchet member 40. The ring tooth portion 41 is formed in an idling state. Otherwise, when the wrench body 10 is rotated counterclockwise, please refer to FIG. 6 at the same time, because the interlocking shaft 33 of the tooth member 30 is pushed by the elastic member 34 and the direction The action of the wrench body 10 is reversed, so that the tooth member 30 cannot be pushed back and the arc is turned The toothed portion 31 does engage the ring tooth portion 41 of the ratchet member 40, thereby driving the ratchet member 40 to rotate and achieve the twisting action of the screw lock unit, thereby forming a driving state of the wrench body 10 counterclockwise one-way twisting.
其次,將該控制件20往另一方向扳動時,再請參閱第7、8圖所示,該掣齒件30則經由該控制件20扳轉作動而抵靠於掣齒槽15之逆時針方向,同時透過該連動軸33以及彈性件34逆時針方向推抵該掣齒件30,當扳手本體10逆時針轉動時,由於該扳手本體10之作動方向與彈性件34推抵方向相同,使該棘輪件40能沿著該彈性件34方向而將該掣齒件30推回,導致該掣齒件30之弧型齒部31無法有效咬合該棘輪件40之環齒部41,形成空轉狀態,反之,將該扳手本體10順時針轉動時,因該掣齒件30之連動軸33受彈性件34推抵方向與該扳手本體10之作動方向相反,使該掣齒件30無法被推回而將弧型齒部31確實咬合該棘輪件40之環齒部41,進而帶動該棘輪件40轉動並達到 螺鎖單元的扭轉作動,藉此形成扳手本體10順時針單向扭轉之驅動狀態。 Next, when the control member 20 is pulled in the other direction, as shown in FIGS. 7 and 8, the tooth member 30 is rotated by the control member 20 to abut against the inverse of the molar groove 15. When the wrench body 10 is rotated counterclockwise, the direction of the action of the wrench body 10 is the same as that of the elastic member 34 when the wrench body 10 is rotated counterclockwise. The ratchet member 40 can be pushed back along the direction of the elastic member 34, so that the arc-shaped tooth portion 31 of the tooth member 30 can not effectively engage the ring tooth portion 41 of the ratchet member 40, forming an idle rotation. In the state, on the other hand, when the wrench body 10 is rotated clockwise, the interlocking shaft 33 of the toothed member 30 is urged by the elastic member 34 in a direction opposite to the operating direction of the wrench body 10, so that the toothed member 30 cannot be pushed. The arc-shaped tooth portion 31 is surely engaged with the ring-toothed portion 41 of the ratchet member 40, thereby driving the ratchet member 40 to rotate and reach The twisting operation of the screw lock unit thereby forming a driving state of the wrench body 10 in a clockwise one-way twist.
藉上述具體實施例之結構,可得到下述之效益:(一)該掣齒件30係由內凹弧槽32透過一軸栓321連接一連動軸33,再以該連動軸33套設一彈性件34並組入該控制件20於軸柱22之穿設孔23內,令控制件20切換操作時,能確實透過連動軸33連動該掣齒件30,同時透過軸栓321形成一連動支點,提升掣齒件30位移作動之順暢度,更讓彈性件34能確實伸縮於該穿設孔23內,避免變形或彈出之故障情況,進而具有穩定操作與增加結構嚙合強度之功效,俾以提高其耐用性;(二)該掣齒件30係經由連動軸33穿套一彈性件34,組合時直接再由連動軸33將該彈性件34限制於該穿設孔23內,即可完成該掣齒件30以及控制件20之連結狀態,有效簡化該扳手本體10之組裝步驟,同時降低結構組裝時間及人力成本,有助於經濟效益的提升。 According to the structure of the above specific embodiment, the following benefits can be obtained: (1) the tooth member 30 is connected to the linkage shaft 33 by the concave arc groove 32 through a shaft bolt 321 , and the elastic shaft 33 is sleeved with an elastic force. The member 34 is incorporated into the through hole 23 of the shaft post 22, so that when the control member 20 is switched, the jaw member 30 can be surely coupled through the linkage shaft 33, and a linkage fulcrum is formed through the shaft bolt 321 The smoothness of the displacement of the tooth member 30 is improved, and the elastic member 34 can be surely stretched and retracted into the through hole 23 to avoid the deformation or ejection failure, thereby having the effect of stable operation and increased structural engagement strength. (2) The gear member 30 is sleeved with an elastic member 34 via the linkage shaft 33, and the elastic member 34 is directly restrained by the linkage shaft 33 in the insertion hole 23 when combined. The connection state of the tooth member 30 and the control member 20 effectively simplifies the assembly step of the wrench body 10, and at the same time reduces structural assembly time and labor cost, and contributes to economic benefit improvement.
