Description

防脫轉接套筒Anti-falling adapter sleeve

本創作係與驅動工具之配件有關，更詳而言之係指一種防脫轉接套筒。This creation is related to the accessories of the drive tool, more specifically, it refers to an anti-dropping adapter sleeve.

按，在欲對一螺帽進行旋緊或旋鬆時，為使能更省力且精確地施力，一般會藉由一轉接套筒暫時性地對接在該螺帽與一驅動工具間，以將該驅動工具所產生之旋轉動力透過該轉接套筒而傳遞至該螺帽上，以達到旋緊螺帽或旋鬆螺帽之功效。惟，如第一圖及第二圖所示，為我國專利證書號數第I690392號所揭之一種套接工具1，該套接工具1係用於套接於一驅動工具90之驅動頭91，該驅動頭91之外周面上設有一扣環92（C形扣環），該套接工具1包括有一接合部2及一作用部3，該接合部2具有自頂面凹入而成之一容置槽4，該容置槽4之側面5為平行於軸向（軸心線）之平面，而該容置槽4之底面6則為錐面（即斜面），該容置槽4能容納該驅動頭91之扣環92，該接合部2上並具有一軸向貫穿該容置槽4之多邊形孔7，該多邊形孔7能容納該驅動頭91，該作用部3則具有一作用孔8，該作用孔8能套接於一螺帽上。藉此，在該驅動頭91與該套接工具1結合時，係先由該套接工具1之容置槽4供該驅動頭91之扣環92容置（如第一圖所示），以讓使用者僅需輕易旋轉該驅動頭91便能對正該多邊形孔7，當對正後，再將該驅動頭91連同該扣環92推入於該多邊形孔7內（如第二圖所示），藉以達到快速完成套接之功能。然，雖然上揭驅動頭91之扣環92係被迫緊在該套接工具1之多邊形孔7中，但該多邊形孔7的孔壁為平直之壁面，且該扣環92一般為稍具彈性變形能力之C形扣環，因此在該驅動頭91旋轉之過程中，若該扣環92被稍微地壓縮而變形時，便極有可能讓該扣環92連同該驅動頭91自該套接工具1之多邊形孔7中脫出（即套接工具1與驅動頭91脫離），其不僅會在使用過程中發生不順暢之情形，更嚴重者，會使該套接工具1被高速甩出，而對使用者造成傷害，進而有安全上之疑慮。再者，上述所揭之套接工具1中，其容置槽4之功能主要在供該驅動頭91上之扣環92的前端進行先行容置，以便後續之旋轉對位推入。但，該容置槽4的側面5為平行於軸向（軸心線）延伸之平面設計，反而會在製造時切削掉過多之材料，不僅造成材料上之浪費及降低剛性上之強度，亦會使得驅動頭91與套接工具1在同步轉動時容易產生晃動與鬆脫之疑慮。 Press, when you want to tighten or loosen a nut, in order to enable a more labor-saving and precise force application, an adapter sleeve is generally used to temporarily butt between the nut and a driving tool. The rotation power generated by the driving tool is transmitted to the nut through the adapter sleeve to achieve the effect of tightening or loosening the nut. However, as shown in the first and second figures, it is a socket tool 1 disclosed in China Patent Certificate No. I690392. The socket tool 1 is used to socket the driving head 91 of a driving tool 90. , The driving head 91 is provided with a buckle 92 (C-shaped buckle) on the outer peripheral surface. The socket tool 1 includes an engaging portion 2 and an acting portion 3. The engaging portion 2 is formed by recessing from the top surface. An accommodating groove 4, the side surface 5 of the accommodating groove 4 is a plane parallel to the axial direction (axis center line), and the bottom surface 6 of the accommodating groove 4 is a tapered surface (that is, an inclined surface), the accommodating groove 4 The buckle 92 of the driving head 91 can be accommodated, the engaging portion 2 has a polygonal hole 7 axially penetrating the accommodating groove 4, the polygonal hole 7 can accommodate the driving head 91, and the acting portion 3 has a The function hole 8 can be sleeved on a nut. Thereby, when the driving head 91 is combined with the socket tool 1, the accommodating groove 4 of the socket tool 1 is used to accommodate the buckle 92 of the driving head 91 (as shown in the first figure), So that the user only needs to easily rotate the driving head 91 to align the polygonal hole 7. After the alignment, the driving head 91 and the buckle 92 are pushed into the polygonal hole 7 (as shown in the second figure). Shown), in order to achieve the function of quickly completing the socket. Of course, although the buckle 92 of the lifting driving head 91 is forced to be tightly fitted in the polygonal hole 7 of the socket tool 1, the hole wall of the polygonal hole 7 is a straight wall, and the buckle 92 is generally slightly C-shaped buckle with elastic deformation ability. Therefore, if the buckle 92 is slightly compressed and deformed during the rotation of the driving head 91, it is very likely that the buckle 92 and the driving head 91 will be removed from the If the socket tool 1 comes out of the polygonal hole 7 (that is, the socket tool 1 is separated from the driving head 91), it will not only be unsmooth during use, but even more serious, it will cause the socket tool 1 to be high-speed Throw it out, and cause harm to the user, and then there are safety concerns. Furthermore, in the socket tool 1 disclosed above, the function of the accommodating groove 4 is mainly for accommodating the front end of the buckle 92 on the driving head 91 in advance for subsequent rotation and positioning. However, the side surface 5 of the accommodating groove 4 is a plane design extending parallel to the axial direction (axis center line), which will cut off too much material during manufacturing, which not only causes waste of materials and reduces the strength of rigidity, but also This will cause the driving head 91 and the socket tool 1 to be susceptible to shaking and loosening when they rotate synchronously.

為使貴審查委員能對本創作之特徵與其特點有更進一步之了解與認同，茲列舉以下之實施例並配合圖式說明如下：請參閱第三圖至第七圖，係本創作第一較佳實施例所提供之一種防脫轉接套筒100，為一體製造而成，主要包含有一位於一端之驅動部10及一與該驅動部10一體同軸連接而位於另一端之作用部20，其中：請參閱第三圖至第五圖，該驅動部10，自其端面（即自由端面）上往內軸向凹陷延伸有一驅動孔11，該驅動孔11為正四邊形孔（或稱四角孔），具有四個軸向延伸之孔壁111。該驅動部10於同一端面往內軸向凹陷延伸有一呈圓環狀傾斜之第一導引斜面12，該第一導引斜面12之頂端與該驅動部10之端面相接，該第一導引斜面12之外徑大於該驅動孔11之孔徑。該驅動孔11之各孔壁111頂端與該第一導引斜面12之底端間並分別形成有一呈傾斜之第二導引斜面13，且該第二導引斜面13係與該第一導引斜面12直接鄰接。該驅動孔11之每一孔壁111上皆分別具有一徑向凹陷之防脫槽14。請參閱第三圖至第五圖，該作用部20，係與該驅動部10一體地同軸連接，該作用部20之端面（即自由端面）上往內軸向凹陷延伸有一作用孔21，該作用孔21為六角孔。該作用部20之外徑與該驅動部10之外徑相同。該作用孔21與該驅動孔11相連通。是以，上述即為本創作第一較佳實施例所提供一種防脫轉接套筒100之各部構件及其組合方式之介紹，接著再將其使用特點介紹如下：首先，請參閱第六圖及第七圖，當本創作欲與一驅動工具90之驅動頭91連結時，由於該驅動頭91鄰近一端之周面上設有一扣環92，因此可先將該扣環92沿著該第一導引斜面12往內置入，並再通過該第一導引斜面12後，再接著置入於該第二導引斜面13中（如第六圖所示），再稍加旋轉本創作，使該驅動頭91與該驅動孔11對正。接著施力將該驅動頭91連同動扣環92推入於該驅動孔11內，並讓該扣環92卡入於該防脫槽14內（如第七圖所示），而使該驅動頭91被迫緊於該驅動孔11中。如此一來，便能由該作用部20之作用孔21與一螺帽、螺栓或螺母（圖中未示）進行套接，以透過本創作之防脫轉接套筒100將該驅動工具90之驅動頭91所產生的旋轉動力傳遞至該螺帽、螺栓或螺母上，以利進行旋鬆或旋緊之作業。當使用者欲將本創作與驅動頭91分離時，則由使用者稍加施力地拉動本創作，而使該扣環92先行內縮而脫離該防脫槽14，再直至脫出於該驅動孔11外。如此一來，由於本創作在該驅動孔11之每一孔壁111上皆分別具有一徑向凹陷之防脫槽14，因此在由本創作對螺帽、螺栓、螺母進行旋鬆或旋緊之作業過程中，該扣環92會被保持在該防脫槽14內，以阻止本創作與該驅動頭91自行產生脫離之情形。是以，由於本創作在該驅動孔11之每一孔壁111上皆分別具有一徑向凹陷之防脫槽14，使讓該扣環92卡抵在該防脫槽14內，以阻止本創作與該驅動頭91自行產生脫離，而能具備更為周全之安全性，以讓作業過程更加順暢。接著，由於本創作在驅動部10之端面至該驅動孔11之孔壁111間，依序設置有第一導引斜面12與相接之第二導引斜面13來方便供扣環92之置入，及驅動頭91之對位，而利用二組斜面之設計來減少所需削去之材料，不僅能減少材料之浪費亦能同時強化整體之剛性。也能減少本創作與驅動頭間之鬆動與晃動，來減少危險情事之發生。上述實施例中，如第五圖所示，該第一導引斜面12向外延伸之虛擬伸延線與該驅動部10端面間之角度θ1為15度至45度間。該第二導引斜面13向外延伸之虛擬伸延線與該驅動部10端面間之角度θ2為40度至80度間。上述第一導引斜面12與該第二導引斜面13傾斜角度範圍，為能同時具備導引、減少削去材料及減少與驅動頭間之鬆動等功效。另外，雖然上述實施例中，該作用孔為六角孔。但實際上，該作用孔亦可為四角孔、八角孔、十二角孔或六角星形孔中之任何一種。其次，雖然上述實施例中，該驅動部與該作用部之外徑相同，但實際上該驅動部之外徑亦可大於該作用部之外徑，或該驅動部之外徑小於該作用部之外徑，或該驅動孔與該作用孔不連通，其皆不影響本創作之功效。雖然上述實施例中，該驅動部之驅動孔在每一孔壁上皆設有一防脫槽。但實際上亦可僅在其中二個相對面之孔壁上具有防脫槽，便足以達到本創作之功效，並能讓本創作適用於其他不同型式之驅動頭，使本創作之適用範圍更加廣泛。請參閱第八圖及第九圖，係本創作第二較佳實施例所提供之一種防脫轉接套筒200，其與上述實施例相同包含有一驅動部30及一作用部40，其中：該驅動部30，自其端面（即自由端面）上往內軸向凹陷延伸有一驅動孔31，該驅動孔31為正四邊形孔，具有四個軸向延伸之孔壁311，每一孔壁311之頂部至該驅動部30之端面間，分別形成有一呈傾斜延伸並逐漸向外擴大之導引斜面35，該導引斜面35向外延伸之虛擬伸延線與該驅動部30端面間之角度θ3為40度至80度間。該驅動孔31至少二相對之孔壁311上分別具有一徑向凹陷之防脫槽34。請參閱第八圖至第九圖，該作用部40，係與該驅動部30一體同軸地連接，該作用部40之端面（即自由端面）上往內軸向凹陷延伸有一作用孔41，該作用孔41為六角孔。是以，雖然在本實施例中係以單一斜度之導引斜面呈現，與第一實施例所揭具有雙斜度之第一導引斜面及第二導引斜面的組合構造不同。但，其皆能達到相同之功效。以上所揭，僅為本創作所提供之較佳實施例而已，並非用以限制本創作之實施範圍，凡本技術領域內之相關技藝者根據本創作所為之均等變化，皆應屬本創作所涵蓋之範圍。 In order to enable your reviewer to have a better understanding and recognition of the features and characteristics of this creation, the following examples are listed below in conjunction with the schematic descriptions: Please refer to the third to seventh figures, which are the anti-dropping adapter sleeve 100 provided by the first preferred embodiment of the present creation. The driving part 10 is integrally and coaxially connected to the acting part 20 at the other end, wherein: Please refer to Figures 3 to 5, the drive portion 10 has a drive hole 11 extending inwardly from its end surface (that is, the free end surface), and the drive hole 11 is a regular quadrilateral hole (or called a quadrangular hole). There are four axially extending hole walls 111. The driving portion 10 extends inwardly on the same end surface with a first guiding slope 12 inclined in an annular shape. The top end of the first guiding slope 12 is connected to the end surface of the driving portion 10, and the first guiding The outer diameter of the inclined surface 12 is larger than the diameter of the driving hole 11. An inclined second guiding inclined surface 13 is formed between the top end of each hole wall 111 of the driving hole 11 and the bottom end of the first guiding inclined surface 12, and the second guiding inclined surface 13 is connected to the first guiding inclined surface 13 The lead slope 12 is directly adjacent to each other. Each hole wall 111 of the driving hole 11 is respectively provided with a radially recessed anti-drop groove 14. Please refer to Figures 3 to 5, the action portion 20 is integrally and coaxially connected with the drive portion 10, and an action hole 21 is axially recessed and extended inwardly on the end surface (that is, the free end surface) of the action portion 20, the The function hole 21 is a hexagonal hole. The outer diameter of the acting portion 20 is the same as the outer diameter of the driving portion 10. The function hole 21 communicates with the driving hole 11. Therefore, the above is the introduction of the various components of the anti-dropping adapter sleeve 100 and the combination method provided by the first preferred embodiment of this creation, and then the use characteristics are introduced as follows: First of all, please refer to the sixth and seventh figures. When this creation is to be connected to the driving head 91 of a driving tool 90, since a buckle 92 is provided on the peripheral surface of the driving head 91 adjacent to one end, the The buckle 92 is inserted along the first guiding inclined surface 12, and after passing through the first guiding inclined surface 12, it is then inserted into the second guiding inclined surface 13 (as shown in the sixth figure), Rotate the creation slightly to make the driving head 91 align with the driving hole 11. Then force the driving head 91 and the moving buckle 92 into the driving hole 11, and the buckle 92 is locked into the anti-drop groove 14 (as shown in the seventh figure), so that the driving The head 91 is forced into the driving hole 11. In this way, the action hole 21 of the action part 20 can be socketed with a nut, bolt or nut (not shown in the figure), so that the driving tool 90 can be moved through the anti-dropping adapter sleeve 100 of the present invention. The rotational power generated by the driving head 91 is transmitted to the nut, bolt or nut to facilitate the loosening or tightening operation. When the user wants to separate the creation from the driving head 91, the user pulls the creation with a little force, so that the buckle 92 is retracted first to escape from the anti-drop groove 14 until it exits the Drive hole 11 outside. In this way, since each hole wall 111 of the driving hole 11 has a radially recessed anti-drop groove 14 in this creation, the nuts, bolts, and nuts are loosened or tightened by this creation. During the operation, the buckle 92 will be held in the anti-drop groove 14 to prevent the original creation from detaching from the driving head 91 by itself. Therefore, since each hole wall 111 of the driving hole 11 has a radially recessed anti-drop groove 14 in the present invention, the buckle 92 is locked in the anti-drop groove 14 to prevent the The creation is separated from the driving head 91 on its own, and can have more comprehensive safety, so that the work process is smoother. Then, because of this creation, between the end surface of the driving part 10 and the hole wall 111 of the driving hole 11, a first guiding inclined surface 12 and a second guiding inclined surface 13 connected to each other are arranged in sequence to facilitate the placement of the buckle 92 It can not only reduce the waste of materials but also strengthen the rigidity of the whole by using the design of two sets of inclined planes to reduce the material that needs to be cut off. It can also reduce the looseness and shaking between the original creation and the driving head to reduce the occurrence of dangerous situations. In the above embodiment, as shown in FIG. 5, the angle θ1 between the virtual extension line extending outward of the first guiding inclined surface 12 and the end surface of the driving portion 10 is between 15 degrees and 45 degrees. The angle θ2 between the virtual extension line extending outward of the second guiding inclined surface 13 and the end surface of the driving portion 10 is between 40 degrees and 80 degrees. The inclination angle range of the first guiding inclined surface 12 and the second guiding inclined surface 13 is capable of guiding, reducing material removal, and reducing looseness between the driving head and the like at the same time. In addition, although in the above-mentioned embodiment, the function hole is a hexagonal hole. But in fact, the function hole can also be any one of four-corner hole, octagonal hole, twelve-corner hole or hexagonal star hole. Secondly, although in the above embodiment, the outer diameter of the driving part and the acting part are the same, in fact the outer diameter of the driving part can be larger than the outer diameter of the acting part, or the outer diameter of the driving part is smaller than the acting part. The outer diameter, or the drive hole and the action hole are not connected, neither affects the effect of this creation. Although in the above-mentioned embodiment, the driving hole of the driving part is provided with an anti-drop groove on each hole wall. But in fact, it is also possible to only have anti-drop grooves on the wall of the two opposite sides of the hole, which is enough to achieve the effect of this creation, and can make this creation suitable for other different types of driving heads, making the scope of application of this creation more widely. Please refer to the eighth and ninth figures, which are the anti-dropping adapter sleeve 200 provided by the second preferred embodiment of the present creation. The same as the above-mentioned embodiment, it includes a driving part 30 and an acting part 40, in which: The drive portion 30 has a drive hole 31 extending inwardly from its end surface (that is, the free end surface). The drive hole 31 is a regular quadrilateral hole and has four axially extending hole walls 311. Each hole wall 311 Between the top of the drive portion 30 and the end surface of the drive portion 30, a guiding inclined surface 35 which extends obliquely and gradually expands outward is respectively formed. The angle θ3 between the virtual extension line of the guiding inclined surface 35 and the end surface of the drive portion 30 It is between 40 degrees and 80 degrees. At least two opposite hole walls 311 of the driving hole 31 each have a radially recessed anti-drop groove 34. Please refer to Figures 8-9. The acting portion 40 is integrally and coaxially connected with the driving portion 30. The end surface (ie, the free end surface) of the acting portion 40 is axially recessed and extending inwardly with an acting hole 41, the The function hole 41 is a hexagonal hole. Therefore, although the present embodiment is presented with a single-slope guiding slope, it is different from the combined structure of the first guiding slope and the second guiding slope with double slopes disclosed in the first embodiment. However, they can all achieve the same effect. The above disclosures are only the preferred embodiments provided by this creation, and are not intended to limit the scope of implementation of this creation. All relevant artisans in the technical field should make equal changes based on this creation and should belong to this creation. The scope of coverage.
