Description
本考案は、ラチェットスパナ構造に関するものであり、さらに詳しくは、構造が簡素化され、強度が強化され、安定的に操作できる回転方向の方向転換可能なラチェットスパナに関するものである。 The present invention relates to a ratchet spanner structure, and more particularly, to a ratchet spanner capable of changing the direction of rotation that can be stably operated with a simplified structure and enhanced strength.
従来のラチェットスパナ構造は、図９のように、スパナ５０の一端に、回転部材６０が組み立てられ、上記回転部材６０が、スパナ５０端部において回転し、ナット及びボルトを締結し又は弛緩することができるように構成されたものである。また、上記回転部材６０の外縁に、歯状リング６１が形成され、上記歯状リング６１の一側において、対応して、ラチェット部材７０が噛合し、上記ラチェット部材７０が、スパナ５０の内部に設けてある第一槽室５１において可動状態になる。そして、上記ラチェット部材７０において、回転部材６０とに噛合する端面の他端面に、円弧面７１が形成される。上記スパナ５０には、第一槽室５１に連通する第二槽室５２を設けてある。上記第二槽室５２に、制御ブロック８０が実装される。上記制御ブロック８０に、挿入孔８１が形成され、また、挿入孔８１に、バネ８２が実装される。バネ８２の頂端に、当接ヘッド８３が嵌設され、当接ヘッド８３が、バネ８２の附勢により、ラチェット部材７０の円弧面７１に当接し、制御ブロック８０で、当接ヘッド８３を制御することにより、ラチェット部材７０が、第一槽室５１の異なる側面に当接する事が選択され、そのため、一方向に駆動する回転効果が得られる。 In the conventional ratchet spanner structure, as shown in FIG. 9, a rotating member 60 is assembled at one end of a spanner 50, and the rotating member 60 rotates at the end of the spanner 50 to fasten or loosen a nut and a bolt. It is configured to be able to. Further, a tooth-shaped ring 61 is formed on the outer edge of the rotating member 60. On one side of the tooth-shaped ring 61, the ratchet member 70 is correspondingly engaged, and the ratchet member 70 is placed inside the spanner 50. The first tank chamber 51 provided is movable. In the ratchet member 70, an arcuate surface 71 is formed on the other end surface of the end surface that meshes with the rotating member 60. The spanner 50 is provided with a second tank chamber 52 that communicates with the first tank chamber 51. A control block 80 is mounted in the second tank chamber 52. An insertion hole 81 is formed in the control block 80, and a spring 82 is mounted in the insertion hole 81. A contact head 83 is fitted on the top end of the spring 82, and the contact head 83 contacts the arcuate surface 71 of the ratchet member 70 by the bias of the spring 82, and the control block 80 controls the contact head 83. By doing so, it is selected that the ratchet member 70 contacts the different side surface of the 1st tank chamber 51, Therefore The rotation effect driven in one direction is acquired.
上記のように、従来構造は、
１．上記ラチェット部材７０と制御ブロック８０との間に、バネ８２と当接ヘッド８３とが設置されて、上記当接ヘッド８３の一端が、バネ８２によって附勢され、当接ヘッド８３の他端が、摺動的にラチェット部材７０の円弧面７１に当接するため、ラチェット部材７０は、スパナ５０を回転させることにより、振動した場合、或いは、制御ブロック８０で切り替える場合、上記当接ヘッド８３の一端が、ラチェット部材７０の円弧面７１を摺動すると、他端が、側方向に、制御ブロック８０の挿入孔８１を摩擦することから、当接ヘッド８３とバネ８２とが、容易に挿入孔８１から、弾み出し、或いは、変形する。そのため、抵抗が形成されて、操作安定性が低下する。また、明らかに、構造の強度不足の問題がある。
As mentioned above, the conventional structure is
1. A spring 82 and a contact head 83 are installed between the ratchet member 70 and the control block 80, one end of the contact head 83 is urged by the spring 82, and the other end of the contact head 83 is When the ratchet member 70 vibrates by rotating the spanner 50 or is switched by the control block 80 in order to abut against the arc surface 71 of the ratchet member 70 slidably, one end of the contact head 83 is used. However, when the arcuate surface 71 of the ratchet member 70 is slid, the other end rubs the insertion hole 81 of the control block 80 in the lateral direction, so that the contact head 83 and the spring 82 can be easily inserted into the insertion hole 81. From, it will spring out or deform. Therefore, resistance is formed and operation stability is lowered. Obviously, there is a problem of insufficient structural strength.
２．上記スパナ５０の組み立てステップは、まず、制御ブロック８０を第二槽室５２に実装し、制御ブロック８０を係合して固定することにより、制御ブロック８０が、回転操作だけできることに制限される。また、第一槽室５１端部からバネ８２を挿入孔８１に設置して、バネ８２の頂端に、上記当接ヘッド８３が嵌設される。第一槽室５１の開口が、回転部材６０へ向かうため、バネ８２を実装することが、容易ではなく、そして、上記バネ８２と当接ヘッド８３の体積が比較的に小さいため、組み立てる過程において、紛失及び落下が容易に発生する。そのため、組み立て工程の難しさがより高くなり、簡単に組み立てることができず、また、部材が多すぎる問題がある。 2. The assembly step of the spanner 50 is limited to the fact that the control block 80 can only be rotated by mounting the control block 80 in the second tank chamber 52 and engaging and fixing the control block 80 first. A spring 82 is installed in the insertion hole 81 from the end of the first tank chamber 51, and the contact head 83 is fitted on the top end of the spring 82. Since the opening of the first tank chamber 51 is directed to the rotating member 60, it is not easy to mount the spring 82, and the volume of the spring 82 and the contact head 83 is relatively small. Loss and fall easily occur. Therefore, the difficulty of an assembly process becomes higher, it cannot assemble easily, and there is a problem that there are too many members.
３．上記ラチェット部材７０と制御ブロック８０との間に、バネ８２と当接ヘッド８３とが設置され、上記当接ヘッド８３の一端が、バネ８２により附勢され、当接ヘッド８３の他端が、摺動的にラチェット部材７０の円弧面７１に当接し、ラチェット部材７０が作動する時、上記当接ヘッド８３が、バネ８２を押さえて伸縮させ、ラチェット部材７０と制御ブロック８０との間に、ラチェット部材７０の可動空間が維持されるため、当接ヘッド８３とバネ８２とが、過度に、挿入孔８１の外へ突出して、当接ヘッド８３とバネ８２との位置付け効果が低減するという問題がある。 3. Between the ratchet member 70 and the control block 80, a spring 82 and a contact head 83 are installed, one end of the contact head 83 is urged by the spring 82, and the other end of the contact head 83 is When the ratchet member 70 is slidably contacted with the arcuate surface 71 of the ratchet member 70 and the ratchet member 70 is operated, the contact head 83 presses and extends the spring 82, and between the ratchet member 70 and the control block 80, Since the movable space of the ratchet member 70 is maintained, the contact head 83 and the spring 82 project excessively outside the insertion hole 81, and the positioning effect of the contact head 83 and the spring 82 is reduced. There is.
かかる背景技術の状況下において、実用新案登録第３１１４１０９号公報（以下、「特許文献１」という。）には、ラチェットレンチのレンチ本体中に溝孔とスプリングが嵌め込まれた改良構造が記載されている。しかし、特許文献１には、スパナについては記載がなく、特に回転方向転換可能な構造のスパナについては十分開示がなく、操作の安定性についても改良の余地がある。
本考案の主な課題は、上記ラチェット部材において、位置制限部に、円柱が固定され、円柱で、バネの一端に当接し、これにより、ラチェット部材と制御部材とが、連動され、また、上記バネの両側において、完全に当接可能なように、Ｕ形部が形成され、制御部材で、切り替えを行う時、上記バネが、側方向の力による変形や弾み出すことなく、安定な操作や構造強度の強化が得られ、耐用性能が向上する方向転換可能なラチェットスパナを提供することにある。 A main problem of the present invention is that in the ratchet member, a cylinder is fixed to the position limiting portion, and the cylinder is in contact with one end of the spring, whereby the ratchet member and the control member are interlocked. A U-shaped part is formed on both sides of the spring so that it can be completely abutted, and when the control member is used for switching, the spring can be operated stably without being deformed or bulged by a lateral force. An object of the present invention is to provide a ratchet wrench capable of changing the direction in which structural strength is enhanced and durability is improved.
本考案の他の課題は、上記制御部材が、直接に、定位孔に、バネが挿設され、バネの両側に設けてあるＵ形部によって制限され、即ち、直接に、制御部材のブロック端部を、スパナ本体の円形孔に設置でき、また、作動口端から、ラチェット部材をラチェット槽内に設置でき、ラチェット部材の位置制限部を制御部材の位置制限欠部に挿設されて、円柱で、バネの他端に当接でき、そのため、容易に、スパナ本体の組み立てステップが完了し、これにより、簡素化の構造や急速に組み立ての実用効果が実現される方向転換可能なラチェットスパナを提供することにある。 Another problem of the present invention is that the control member is directly limited by the U-shaped portions provided on both sides of the spring, with the spring inserted in the stereotaxic hole, that is, directly on the block end of the control member. Can be installed in the circular hole of the spanner body, the ratchet member can be installed in the ratchet tank from the end of the operating port, and the position restricting portion of the ratchet member is inserted into the position restricting notch portion of the control member. Therefore, the assembly step of the spanner body can be easily completed by this, so that the reversible ratchet spanner that can realize the simplified structure and the practical effect of assembly rapidly can be obtained. It is to provide.
本考案の更に他の課題は、上記Ｕ形部において、バネの両側の外縁に、ともに、円弧面が形成され、上記ラチェット部材において、円柱の近くに、円弧空間が形成され、円弧空間で、円弧面に合わせて、ラチェット部材とＵ形部とが、干渉なく退避でき、即ち、ラチェット部材と制御部材との間の距離が短縮され、Ｕ形部が、円柱の両側に囲むように、ラチェット部材の定位効果が向上する方向転換可能なラチェットスパナを提供することにある。 Still another problem of the present invention is that, in the U-shaped portion, an arc surface is formed on both outer edges of the spring, and in the ratchet member, an arc space is formed near the cylinder, The ratchet member and the U-shaped part can be retracted without interference in accordance with the arc surface, that is, the distance between the ratchet member and the control member is shortened, and the ratchet is surrounded by both sides of the cylinder. An object of the present invention is to provide a ratchet spanner capable of changing the direction in which the localization effect of the member is improved.
そこで、本考案者は、上記の本考案の課題を解決するため鋭意検討を重ねた結果、後述のように、制御部材とラチェット部材を備え、制御部材の切換え制御により回転部材の回転方向を転換可能とすることにより、上記課題を解決できることに着目し、本考案に想到するに至った。 Therefore, as a result of intensive studies to solve the above-described problems of the present invention, the present inventor has a control member and a ratchet member as described later, and changes the rotation direction of the rotation member by switching control of the control member. Focusing on making it possible to solve the above problems, the present inventors have come up with the present invention.

本考案によれば、図２と図３、図５及び図６のように、上記制御部材２０は、Ｕ形部２４に装填してあるバネ２５で、斜めにラチェット部材３０の円柱３３に当接し、ラチェット部材３０が、ラチェット槽１４の一側に位置し、また、ラチェット部材３０の円弧状歯部３１が、回転部材４０の歯状リング４３に噛合する。この状態で、上記バネ２５の両端が、それぞれ、定位孔２４１と円柱３３によって固定される。また、上記バネ２５の両側が、完全に閉鎖されるように、Ｕ形部２４が設けられるため、制御部材２０で切り替える時、上記バネ２５が、側方向の力による変形や弾みだされることなく、より安定的な操作効果が得られる。また、制御部材２０が、摘部２２によって、時計回りに切り替えられて当接する時、時計回りにスパナ本体１０を回転すると、回転部材４０が、反作用力を発生し、上記回転部材４０の歯状リング４３が、逆時計回りに、ラチェット部材３０の円弧状歯部３１を駆動し、ラチェット部材３０が、ラチェット槽１４の一側に当接し、これにより、ナットやボルトを締めることができる。 According to the present invention, as shown in FIGS. 2, 3, 5, and 6, the control member 20 is slanted against the cylinder 33 of the ratchet member 30 with the spring 25 loaded in the U-shaped portion 24. The ratchet member 30 is positioned on one side of the ratchet tank 14, and the arcuate tooth portion 31 of the ratchet member 30 meshes with the toothed ring 43 of the rotating member 40. In this state, both ends of the spring 25 are fixed by the localization hole 241 and the cylinder 33, respectively. Further, since the U-shaped portion 24 is provided so that both sides of the spring 25 are completely closed, the spring 25 is deformed or bounced by a lateral force when switched by the control member 20. And a more stable operation effect can be obtained. Further, when the control member 20 is switched clockwise by the knob 22 and abuts, if the spanner body 10 is rotated clockwise, the rotating member 40 generates a reaction force, and the tooth shape of the rotating member 40 is increased. The ring 43 drives the arcuate tooth portion 31 of the ratchet member 30 in the counterclockwise direction, and the ratchet member 30 comes into contact with one side of the ratchet tank 14, whereby the nut and the bolt can be tightened.
更に、逆時計回りにスパナ本体１０を回転させる場合、上記回転部材４０が、反作用力を発生し、回転部材４０の歯状リング４３が、時計周りにラチェット部材３０の円弧状歯部３１を駆動し、バネ２５の弾性と、ラチェット槽１４のもう一側が中空になることとにより、ラチェット部材３０が、斜めに制御部材２０端部へ向かって変位して、ラチェット部材３０の円柱３３を、Ｕ形部２４内へ変位させる。その結果、回転部材４０とラチェット部材３０とが、分離する。また、上記ラチェット部材３０が、バネ２５によって押し出されて、往復に振動させるため、スパナ本体１０のアイドルの操作効果が得られる。即ち、一方向に、ナットやボルトを締める効果が得られる。 Further, when the spanner body 10 is rotated counterclockwise, the rotating member 40 generates a reaction force, and the toothed ring 43 of the rotating member 40 drives the arcuate tooth portion 31 of the ratchet member 30 clockwise. Then, due to the elasticity of the spring 25 and the other side of the ratchet tank 14 becoming hollow, the ratchet member 30 is displaced obliquely toward the end of the control member 20, and the column 33 of the ratchet member 30 is moved to the U Displace into shape 24. As a result, the rotating member 40 and the ratchet member 30 are separated. Further, since the ratchet member 30 is pushed out by the spring 25 and reciprocally vibrates, an idling operation effect of the spanner body 10 can be obtained. That is, the effect of tightening the nut or bolt in one direction can be obtained.
逆に、制御部材２０の摘部２２が、逆時針周りに切り替えられて当接する時、図７と図８のように、逆時針周りにスパナ本体１０を回転させると、回転部材４０が、反作用力を発生し、上記回転部材４０の歯状リング４３が、時針周りにラチェット部材３０の円弧状歯部３１を駆動し、同じように、ラチェット部材３０が、ラチェット槽１４の一側に当接でき、これにより、ナットやボルトを緩める効果が実現される。また、上記の時針周りにスパナ本体１０を回転する時、回転部材４０の歯状リング４３が、逆時針周りにラチェット部材３０の円弧状歯部３１を駆動し、バネ２５の弾性と、ラチェット槽１４のもう一側が中空になることとにより、ラチェット部材３０が、斜めに制御部材２０端へ向かって変位し、一方向に、ナットやボルトを回転させる効果が実現される。
上記実施形態の構造によれば、次のような利点が得られる。
On the contrary, when the knob 22 of the control member 20 is switched around the reverse hour hand and is brought into contact, as shown in FIGS. 7 and 8, when the spanner body 10 is rotated around the reverse hour hand, the rotating member 40 is reacted. The tooth-shaped ring 43 of the rotating member 40 drives the arc-shaped tooth portion 31 of the ratchet member 30 around the hour hand, and the ratchet member 30 abuts on one side of the ratchet tank 14 in the same manner. This can achieve the effect of loosening the nuts and bolts. Further, when the spanner body 10 is rotated around the hour hand, the toothed ring 43 of the rotating member 40 drives the arcuate tooth portion 31 of the ratchet member 30 around the reverse hour hand, and the elasticity of the spring 25 and the ratchet tank By making the other side of 14 hollow, the ratchet member 30 is displaced obliquely toward the end of the control member 20, and an effect of rotating a nut or a bolt in one direction is realized.
According to the structure of the above embodiment, the following advantages can be obtained.
１．上記ラチェット部材３０は、位置制限部３２に、円柱３３が固定され、円柱３３で、バネ２５の一端に当接し、これにより、ラチェット部材３０と制御部材２０とが、連動し、また、上記バネ２５の両側に、更に、完全に、Ｕ形部２４によって囲まれ、制御部材２０で切り替えを行う時、上記バネ２５が、側方向からの力により、変形することや弾みだされることを防止でき、そのため、安定的に操作することや構造強度の強化が実現され、耐用性能を向上させることができる。 1. The ratchet member 30 has a column 33 fixed to the position restricting portion 32 and is in contact with one end of the spring 25 by the column 33, whereby the ratchet member 30 and the control member 20 are interlocked, and the spring Further, the spring 25 is completely surrounded by the U-shaped portion 24 on both sides of the 25, and when the control member 20 performs switching, the spring 25 is prevented from being deformed or pushed out by a force from the side. Therefore, stable operation and strengthening of structural strength can be realized, and durability can be improved.
２．上記制御部材２０は、定位孔４１に、バネ２５が直接に挿設され、また、Ｕ形部２４が、バネ２５の両側を囲むため、直接に、制御部材２０のブロック２３端部を、スパナ本体１０の円形孔１３に設置でき、また、作動口１２端から、ラチェット部材３０をラチェット槽１４内に設置し、ラチェット部材３０の位置制限部３２が、制御部材２０の位置制限欠部２６に挿設され、円柱３３が、バネ２５の他端に当接するため、簡単に、スパナ本体１０の組み立てステップを終了でき、構造の簡素化や快速的に組み立ての効果が得られる。 2. In the control member 20, the spring 25 is directly inserted into the stereotaxic hole 41, and the U-shaped portion 24 surrounds both sides of the spring 25. Therefore, the end of the block 23 of the control member 20 is directly connected to the spanner. The ratchet member 30 can be installed in the ratchet tank 14 from the end of the operation port 12, and the position restricting portion 32 of the ratchet member 30 is connected to the position restricting notch portion 26 of the control member 20. Since the cylinder 33 is inserted into contact with the other end of the spring 25, the assembly step of the spanner body 10 can be easily completed, and the structure can be simplified and the assembly effect can be obtained quickly.
３．上記Ｕ形部２４は、バネ２５の両側の外縁に、ともに、円弧面２４２が形成され、上記ラチェット部材３０は、円柱３３の近くに、円弧空間３２１が形成され、円弧空間３２１で、円弧面２４２に合わせて、ラチェット部材３０とＵ形部２４とが、互いに退避できる効果が得られる。即ち、ラチェット部材３０と制御部材２０との距離が短縮され、Ｕ形部２４が、円柱３３の両側に当接でき、ラチェット部材３０の定位効果が向上する。 3. The U-shaped portion 24 is formed with an arc surface 242 on both outer edges of the spring 25, and the ratchet member 30 is formed with an arc space 321 near the cylinder 33. According to 242, the effect that the ratchet member 30 and the U-shaped portion 24 can be retracted from each other is obtained. That is, the distance between the ratchet member 30 and the control member 20 is shortened, and the U-shaped portion 24 can abut on both sides of the cylinder 33, so that the localization effect of the ratchet member 30 is improved.
