Description
本創作與棘輪扳手有關，尤指一種改良換向結構之棘輪扳手。This creation is related to a ratchet wrench, especially a ratchet wrench with a modified reversing structure.
習用之具有換向結構的棘輪扳手如第８、９圖所示，其於一扳手本體５中具有一個軸向槽５１以供容設一棘輪５２，且有一控制槽５３連通於該軸向槽５１，該控制槽５３中容設有一嚙合於該棘輪５２之棘動件５４；而一撥動件６設於一樞槽５５中，且能夠帶動一個銷６１擺動，而銷６１利用彈簧６２頂推而接觸在棘動件５４上，俾供使用者藉由切換撥動件６的方向來達到撥動棘動件５４的功能，並獲得切換棘輪５２轉動方向的效果，方便於進行旋緊或旋鬆的工作。而其中銷６１的作用除了用來撥動棘動件５４以切換棘輪５２之轉動方向外，尚具有受該控制槽５３槽壁的擋止而固定其位置，連帶令該撥動件６固定於該樞槽５５中，防止這些零件從扳手本體５中脫落。A ratchet wrench having a reversing structure as shown in FIGS. 8 and 9 has an axial groove 51 in a wrench body 5 for receiving a ratchet 52, and a control groove 53 communicates with the axial groove. 51, the control slot 53 is provided with a ratchet member 54 that is engaged with the ratchet 52; and a dial member 6 is disposed in a pivot slot 55, and can drive a pin 61 to swing, and the pin 61 is spring-loaded with a spring 62 Pushing and contacting on the ratchet member 54, the user can achieve the function of dialing the ratchet member 54 by switching the direction of the dial member 6, and obtain the effect of switching the rotation direction of the ratchet 52, which is convenient for tightening or Unscrew the work. Wherein, in addition to the action of the pin 61 for dialing the ratchet member 54 to switch the direction of rotation of the ratchet 52, the pin 61 is fixed by the stop of the slot wall of the control slot 53, and the strap is fixed to the dial member 6 In the pivot groove 55, these parts are prevented from coming off the wrench body 5.
惟由於銷６１須兼顧固定各零件位置的功能，令其在撥動棘動件５４的功能上，僅能頂推在該棘動件５４的頂端，如此之結構配置將會造成銷６１在撥動棘動件５４的功能上，因為頂抵於棘動件５４的頂端而形成力量集中於此處，容易導致棘動件５４的底端與棘輪５２間的嚙合不確實而有滑脫的現象發生，影響棘輪扳手的正常使用，尤其如應用於較大尺寸之扳手，滑脫現象更易發生。However, since the pin 61 has to take into account the function of fixing the position of each part, it can only push the top end of the ratchet member 54 in the function of the dialing pawl 54. Such a configuration will cause the pin 61 to be dialed. The function of the movable ratchet member 54 is that the force is concentrated on the top end of the ratchet member 54 to cause the force to concentrate there, which may cause the meshing between the bottom end of the ratchet member 54 and the ratchet 52 to be unsatisfactory and slippery. Occurs, affecting the normal use of the ratchet wrench, especially if applied to a larger size wrench, the slippage phenomenon is more likely to occur.
另外，仍是由於銷６１具有撥動棘動件５４與固定各零件位置的雙重功能，以致於在組裝棘輪扳手時必須一次地將棘輪、棘動件及撥動件安裝於對應的位置上，其組裝工序的選擇自由度僅此一個，而無因應實際作業情況的彈性調整空間。In addition, the pin 61 has the dual function of dialing the ratchet member 54 and fixing the position of each component, so that the ratchet wheel, the ratchet member and the dial member must be installed at corresponding positions once when assembling the ratchet wrench. The selection freedom of the assembly process is only one, and there is no flexibility adjustment space in response to actual work conditions.
有鑑於此，故如何解決上述問題即為本創作所欲解決之首要課題，因此本案創作人經過不斷的苦思與試作後才終於有本創作之產生。In view of this, how to solve the above problems is the primary problem that the creative office wants to solve. Therefore, the creators of this case finally have the creation of this creation after continuous hard work and trials.

One end of the wrench body 1 is provided with a through axial groove 11 for receiving the ratchet wheel 2 therein. In the embodiment, as shown in FIG. 3, one end opening of the axial groove 11 is formed to be flat toward the opening. The tapered opening 111 is configured to limit the position of the ratchet 2 in the axial slot 11, and the other end of the axial slot 11 is provided with a stepped slot 112 and is provided with a stepped ring 113. The ratchet 2 is confined in the axial groove 11 (see Fig. 2).
如第２圖搭配第５圖所示，該軸向槽１１一側開設有一與該軸向槽１１相連通的控制槽１２，而該棘動件３設於該控制槽１２中。該棘動件３一側設有多數棘齒３１，且可擺動地設於該控制槽１２中並以其棘齒３１與該棘輪２嚙合，其中該棘動件３乃可選擇地以其棘齒３１的左半部或右半部分別嚙合於該棘輪２，而切換該棘輪２的轉動方向。又該扳手本體１更設有一樞槽１３連通於該控制槽１２，該撥動件４可樞擺地設於該樞槽１３中，其中該撥動件４設有伸出該樞槽１３外之撥動部４１，且該撥動件４具有一第一容置孔４２，該第一容置孔４２中依序填入一第一彈性件４２１及一第一頂推件４２２，該第一頂推件４２２受該第一彈性件４２１之頂推而伸出該第一容置孔４２，而該棘動件３面向該樞槽１３之一側設有一抵接部３２，其中該抵接部３２為一凹穴，俾供該第一頂推件４２２頂抵於該抵接部３２，而可藉由撥動該撥動部４１以樞轉該撥動件４，帶動該第一頂推件４２２朝左或朝右樞擺，藉以撥動該棘動件３朝左或朝右樞擺，而可選擇性地控制棘動件３與棘輪２的嚙合以切換棘輪２的轉動方向。As shown in FIG. 2 and FIG. 5 , a control slot 12 communicating with the axial slot 11 is defined in a side of the axial slot 11 , and the ratchet member 3 is disposed in the control slot 12 . A plurality of ratchet teeth 31 are disposed on one side of the ratchet member 3, and are swingably disposed in the control slot 12 and mesh with the ratchet wheel 2 with its ratchet teeth 31, wherein the ratchet member 3 is optionally a spine thereof The left or right half of the tooth 31 is engaged with the ratchet 2, respectively, and the direction of rotation of the ratchet 2 is switched. Further, the wrench body 1 is further provided with a pivot slot 13 communicating with the control slot 12, and the dial member 4 is pivotally disposed in the pivot slot 13, wherein the dial member 4 is disposed outside the pivot slot 13 The first accommodating hole 42 is sequentially inserted into a first elastic member 421 and a first urging member 422, and the first accommodating hole 42 is sequentially inserted into the first accommodating hole 42. A pushing member 422 is pushed by the first elastic member 421 and protrudes from the first receiving hole 42. The side of the rocking member 3 facing the pivoting groove 13 is provided with an abutting portion 32. The connecting portion 32 is a recess for the first pushing member 422 to abut against the abutting portion 32, and the first pushing member 41 is used to pivot the dialing member 4 to drive the first portion. The pushing member 422 pivots to the left or to the right, thereby pivoting the ratchet member 3 to the left or to the right, and selectively controls the engagement of the ratchet member 3 with the ratchet 2 to switch the rotation direction of the ratchet 2 .
而於本創作中，該撥動件４是以卡掣於該樞槽１３中的卡掣結構之方式以定位於該樞槽１３中。細言之，該撥動件４朝外伸設有一卡掣部，而該樞槽１３之周壁上環設有一環槽１３１，且該環槽１３１靠近該樞槽１３開口處形成有一階面１３２，俾供該撥動件４設於該樞槽１３同時以其卡掣部卡掣於該環槽１３１中，並受該階面１３２擋止其沿軸向脫出該樞槽１３，而令該撥動件４定位於該樞槽１３中。其中該撥動件４之正視圖如第４圖所示，其具有一柱狀本體４３，並於底部之兩側分別朝上伸出一翼部４４，該二翼部４４之末端再朝外形成逆止部４４１，其中該二翼部４４具有彈性而可稍微朝該柱狀本體４３靠近變形，此翼部結構可藉由在該柱狀本體４３兩側各嵌設一彈片構成，而於本實施例中，該二翼部４４為自該柱狀本體４３朝兩側一體延伸而出所形成。此翼部結構俾供如第５圖所示者，將該撥動件４朝下裝入該樞槽１３時，該翼部４４受擠壓而通過該樞槽１３之開口後，遇到該環槽１３１即張開而以其逆止部４４１卡掣於其中，並受該階面１３２擋止而無法退出該樞槽１３，藉此將該撥動件４定位於該樞槽１３中。In the present invention, the dial member 4 is positioned in the pivot slot 13 in a manner of a latch structure that is snapped into the pivot slot 13. In detail, the dialing member 4 has a latching portion extending outwardly, and a ring groove 131 is formed in the ring wall of the pivoting slot 13 , and a ring surface 132 is formed near the opening of the pivot slot 13 . The dialing member 4 is disposed on the pivoting slot 13 and is latched in the ring groove 131 by the latching portion thereof, and is blocked by the stepped surface 132 to axially disengage the pivoting slot 13 The dial 4 is positioned in the pivot slot 13. The front view of the dial member 4 is as shown in FIG. 4, and has a columnar body 43 with a wing portion 44 extending upwardly on both sides of the bottom portion, and the ends of the two wing portions 44 are formed outward again. The backrest portion 441, wherein the two wing portions 44 have elasticity and can be slightly deformed toward the columnar body 43. The wing structure can be formed by embedding a spring piece on each side of the columnar body 43. In the embodiment, the two wing portions 44 are formed integrally extending from the columnar body 43 toward both sides. The wing structure is provided as shown in FIG. 5, and when the dial member 4 is mounted downwardly into the pivot slot 13, the wing portion 44 is pressed and passes through the opening of the pivot slot 13, and is encountered. The ring groove 131 is opened and the backrest portion 441 is locked therein, and is blocked by the step surface 132 so as not to be withdrawn from the pivot groove 13, whereby the dial member 4 is positioned in the pivot groove 13.
藉由以上結構，本創作之優點在於利用該撥動件４之卡掣部卡掣於樞槽１３中，達到定位扳手中各零件的功效。換言之，即是將習用結構中的銷同時兼具頂推棘動件及定位零件的雙重功效分開，令本創作中的第一頂推件４２２單一地發揮頂推棘動件３的作用，藉此可使該第一頂推件４２２的位置不受限制，而可選擇頂推於該棘動件３上的較適當之高度位置，例如中點，使該棘動件３所受到的頂推力量較為平均，避免力量過於集中於棘動件３一端使其翹起，而讓棘動件３與棘輪２之嚙合不確實。With the above structure, the advantage of the present invention is that the latch portion of the dial member 4 is clamped in the pivot slot 13 to achieve the function of each component in the positioning wrench. In other words, the pin in the conventional structure has the dual functions of pushing the ratchet and the positioning component at the same time, so that the first pushing member 422 in the present creation acts as a single pusher 3, Therefore, the position of the first pushing member 422 can be unrestricted, and a suitable height position, such as a midpoint, pushed on the ratchet member 3 can be selected to push the ratchet member 3 The force is relatively average, and the force is prevented from being too concentrated on one end of the ratchet member 3 to make it lift, and the engagement of the ratchet member 3 with the ratchet 2 is not true.
此外，本創作之另一個優點在於利用該撥動件４以其卡掣部卡掣於樞槽１３中之定位方式，而可令整個棘輪扳手的各部零件組裝工序具有多種選擇的自由度。細言之，除了可如同習用結構一般，一次性地將棘輪２、棘動件３及撥動件４安裝於扳手中對應的位置上，亦可分段地先將撥動件４組裝於樞槽１３中，並藉卡掣部卡掣於樞槽１３中的環槽１３１而定位，接著在下一個工序中再將棘輪２及棘動件３組裝於軸向槽１１及控制槽１２中。如此形成不同的組裝流程，而可具有依實際組裝作業情況的彈性調整空間。In addition, another advantage of the present invention is that the dialing member 4 can be positioned in the pivoting slot 13 by the latching portion thereof, so that the various parts assembling processes of the entire ratchet wrench can have various degrees of freedom of choice. In short, in addition to the conventional structure, the ratchet 2, the ratchet member 3 and the dial member 4 can be mounted at a corresponding position in the wrench at a time, and the dial member 4 can be assembled to the pivot first. The groove 13 is positioned by the ring groove 131 in the pivot groove 13 and then the ratchet 2 and the ratchet 3 are assembled in the axial groove 11 and the control groove 12 in the next process. This forms a different assembly process, and can have an elastic adjustment space depending on the actual assembly work.
而第６圖所示者為本創作之第二實施例，本實施例與上述第一實施例之差異在於該撥動件４之卡掣部的實施態樣不同。於本實施例中，該撥動件４之卡掣部包括有一第二頂推件４５２及一第二彈性件４５１，其中該撥動件４於該第一容置孔４２之上方設有一第二容置孔４５，並依序填入該第二彈性件４５１及該第二頂推件４５２，俾供該第二頂推件４５２受該第二彈性件４５１之頂推而伸出該第二容置孔４５。據此，該撥動件４裝入該樞槽１３中後，該第二頂推件４５２伸入該樞槽１３之環槽１３１而卡掣於其中，並受該階面１３２擋止而令該第二頂推件４５２無法沿該樞槽１３之軸向脫出該樞槽１３，連帶令該撥動件４定位於該樞槽１３中。本實施例乃藉由此卡掣部之實施態樣，亦同樣可達到將該撥動件４定位於樞槽１３中的功效，而使該第一頂推件４２２可僅單一地肩負頂推棘動件３的任務，令其可選擇頂推於該棘動件３上的較適當位置，例如中點，使該棘動件３所受到的頂推力量較為平均，避免發生槓桿作用使棘動件３之一端翹起而讓棘動件３與棘輪２之嚙合不確實。The figure shown in FIG. 6 is the second embodiment of the creation. The difference between the embodiment and the first embodiment is that the implementation of the latch portion of the dial member 4 is different. In the embodiment, the latching portion of the dialing member 4 includes a second pushing member 452 and a second elastic member 451. The dialing member 4 is disposed above the first receiving hole 42. The second hole 451 is inserted into the second elastic member 451 and the second pushing member 452, and the second pushing member 452 is pushed by the second elastic member 451 to extend the first hole. Two holes 45 are accommodated. Accordingly, after the dialing member 4 is inserted into the pivoting slot 13, the second pushing member 452 extends into the annular groove 131 of the pivoting slot 13 and is locked therein, and is blocked by the step 132. The second pushing member 452 cannot be disengaged from the pivot slot 13 along the axial direction of the pivot slot 13, and the strap is positioned to position the dial member 4 in the pivot slot 13. In this embodiment, the effect of positioning the dial member 4 in the pivot slot 13 can also be achieved by the embodiment of the latching portion, so that the first pushing member 422 can only push the single thruster. The task of the ratchet member 3 is such that it can be selectively pushed to a suitable position on the ratchet member 3, such as a midpoint, so that the thrusting force received by the ratchet member 3 is relatively average, and the leverage is prevented from being caused by the ratchet. One end of the movable member 3 is tilted to make the engagement of the ratchet member 3 and the ratchet 2 inaccurate.
再者，本創作之第三實施例是在該撥動件之撥動部形成與上述兩實施例之細微差異。於本實施例中，該樞槽乃貫穿該扳手本體，而於該扳手本體兩側分別具有一開口，而該撥動件可以上述兩實施例其中之一的實施態樣卡掣於該樞槽中，並自該二開口分別伸出一撥動部。細言之，如第７圖所示，本實施例以上述第二實施例之實施態樣，亦即透過兩個頂推件４２２、４５２分別肩負卡掣於該樞槽１３之環槽１３１及頂推棘動件３之任務，而該撥動件４之兩端分別自該樞槽１３之兩端開口１３３、１３４伸出一撥動部４１Ａ、４１Ｂ，此二撥動部４１Ａ、４１Ｂ分別位於該扳手本體１的兩側，可便於使用者撥動。Furthermore, the third embodiment of the present invention forms a slight difference from the above two embodiments in the toggle portion of the dial member. In the embodiment, the pivoting groove extends through the wrench body, and has an opening on each side of the wrench body, and the dialing member can be engaged in the pivoting slot in an embodiment of the two embodiments. And extending a dialing portion from the two openings. In detail, as shown in FIG. 7 , in the embodiment of the second embodiment, the two thrusting members 422 and 452 are respectively engaged with the ring groove 131 of the pivot slot 13 and The action of pushing the ratchet member 3, and the two ends of the dialing member 4 respectively protrude from the two end openings 133, 134 of the pivoting slot 13 by a dialing portion 41A, 41B, and the two dialing portions 41A, 41B respectively Located on both sides of the wrench body 1, it is convenient for the user to move.
惟，以上所述實施例之揭示乃用以說明本創作，並非用以限制本創作，故等效元件之置換仍應隸屬本創作之範疇。However, the above description of the embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of the present invention.
綜上所述，本創作已具有相當的進步性及實用性，且經以上詳細說明後，可使熟知本項技藝者明瞭本創作的確可達成前述目的，實已符合專利法之規定，故本案創作人爰依法提出申請。In summary, this creation has been quite progressive and practical, and after detailed description above, it can be made clear to the skilled person that the creation can achieve the above objectives, and it has already met the requirements of the Patent Law.
