Abstract
Description
本發明係與套筒有關,更詳而言之係指一種具彈性結合定位之套筒。The present invention relates to a sleeve, and more specifically, it refers to a sleeve with elastic binding positioning.
按,如第一圖所示,套筒1主要係用以作為套筒扳手與欲扳轉物體(如六角螺絲等)間之扳轉連結介面,其外廓橫斷面呈六角形。惟,為使套筒1與套筒扳手9間能進行暫時性地結合定位,早期之套筒1會在其外周面之端角處開設若干之缺槽2,並在套筒扳手9之套孔內周壁設置一C形扣環8,使當該套筒1與該套筒扳手9結合時,如第二、三圖所示,可由該套筒扳手9上之C形扣環8與該套筒1上之缺槽2進行暫時性地嵌接結合定位,以防止套筒1自行自該套筒扳手9上脫離。然而,此種設計,除必須在套筒1上開設缺槽2外,更僅能與專用之套筒扳手9(設有C形扣環8之套筒扳手9)搭配使用,不僅須額外支出購買專用套筒扳手9之費用,更導致在使用上容易受到限制。
另外,目前亦有一種套筒3,如第四、五圖所示,係在其外周面上開設有徑向環狀之卡槽4,以供一C形扣環5卡置,以讓此種套筒3可與現有之套筒扳手6搭配,而無須購買專用之套筒扳手。然而,此種套筒6由於必須卡入C形扣環5,因此卡槽4之槽深較深,導致套筒6原本所具備之厚度D,在卡槽4位置處之厚度d便變薄了,導致強度降低,而有容易損壞及使用壽命縮短之問題。As shown in the first figure, the sleeve 1 is mainly used as a turning connection interface between a socket wrench and an object to be turned (such as a hexagonal screw, etc.), and its outer cross section is hexagonal. However, in order to enable temporary joint positioning between the socket 1 and the socket wrench 9, the early socket 1 will open a number of notches 2 at the end corners of its outer peripheral surface, and set the socket 1 on the socket wrench 9 A C-shaped retaining ring 8 is provided on the inner peripheral wall of the hole, so that when the socket 1 is combined with the socket wrench 9, as shown in the second and third figures, the C-shaped retaining ring 8 on the socket wrench 9 and the socket The notch 2 on the sleeve 1 is temporarily engaged and positioned to prevent the sleeve 1 from detaching from the sleeve wrench 9 by itself. However, this design, in addition to having a slot 2 on the sleeve 1, can only be used with a special socket wrench 9 (a socket wrench 9 with a C-shaped retaining ring 8), which not only requires additional expenses The cost of purchasing a special socket wrench 9 also makes it easy to be restricted in use.
In addition, there is also a sleeve 3, as shown in Figures 4 and 5, which is provided with a radially annular locking groove 4 on its outer peripheral surface for a C-shaped retaining ring 5 to be locked. This kind of socket 3 can be matched with the existing socket wrench 6 without purchasing a special socket wrench. However, since this sleeve 6 must be snapped into the C-shaped retaining ring 5, the groove depth of the slot 4 is deeper, which causes the thickness D of the sleeve 6 originally, and the thickness d at the position of the slot 4 becomes thinner. As a result, the strength is reduced, and there are problems of easy damage and shortened service life.
有鑑於此,為改善先前技術中,習知套筒有著必須與專用套筒扳手搭配才具有暫時性結合定位功效,而有使用上受到限制及必須額外支出購買專用套筒扳手之費用問題,及在套筒上設置C形扣環會導致整體強度降低,而有容易損壞及使用壽命縮短之問題;緣此,本發明乃提供一種具彈性結合定位之套筒,其主要包含有一套筒本體及一彈性定位體;該套筒本體具有一驅動部及一與該驅動部同軸一體連接之扳轉部,該驅動部之外周面具有一環槽,該彈性定位體呈C形薄片狀,具有一頂端、一位於該頂端相對端位置之底端及一連接於該頂端與該底端間之徑向變形部,該徑向變形部可受外力作用進行徑向之彈性變形,該彈性定位體之頂端與該底端係卡接於該套筒本體之環槽中,該徑向變形部則凸出於該環槽外;藉以不僅能達到與現有之套筒扳手進行暫時性結合定位之功效,更能因而減少環槽所需之開設深度,以維整體之強度,進而增進使用壽命等功效。In view of this, in order to improve the prior art, the conventional sleeve has to be matched with a special socket wrench to have a temporary combined positioning effect, and there are problems with the use of the socket and the cost of purchasing a special socket wrench, and Providing a C-shaped buckle on the sleeve will cause the overall strength to decrease, and there are problems of easy damage and shortened service life; therefore, the present invention provides a sleeve with elastic binding positioning, which mainly includes a sleeve body and An elastic positioning body; the sleeve body has a driving portion and a turning portion which is coaxially and integrally connected with the driving portion; a ring groove is formed on the outer periphery of the driving portion; the elastic positioning body is in a C-shaped sheet shape and has a top end A bottom end located at the opposite end position of the top end and a radial deformation part connected between the top end and the bottom end, the radial deformation part can be elastically deformed radially by an external force, and the top end of the elastic positioning body It is engaged with the bottom end in the ring groove of the sleeve body, and the radial deformation part protrudes out of the ring groove; thus, it can not only achieve temporary binding with the existing socket wrench. Orientation of efficacy, thus reducing more open annular groove of the desired depth, dimensions of the overall intensity, and other effects further enhance the service life.

為使貴 審查委員能對本發明之特徵與其特點有更進一步之了解與認同,茲列舉以下較佳之實施例並配合圖式說明如下:
請參閱第六圖至第九圖,係本發明一較佳實施例所提供之一種具彈性結合定位之套筒100,其主要包含有一套筒本體10及一彈性定位體20,其中:
請參閱第六圖至第九圖,該套筒本體10,具有一驅動部11及一與該驅動部11同軸一體連接之扳轉部12,該驅動部11之外廓橫斷面呈六角形,該驅動部11之自由端具有一往內延伸之驅動孔111,於本實施例中該驅動孔111為四角孔,該驅動部11之外周面上具有一環槽112,該扳轉部12之自由端具有一往內延伸之扳轉孔121,該扳轉孔121與該驅動孔111連通,且該扳轉孔121之孔徑大於該驅動孔111之孔徑,於本實施例中該扳轉孔121為六角孔。
請參閱第六圖至第九圖,該彈性定位體20,由金屬製成,呈C形薄片狀,其可界定出一頂端21、一位於該頂端相對端位置之底端22及一連接於該頂端21與該底端22間之徑向變形部23,該徑向變形部23可受外力作用進行徑向之彈性變形;該彈性定位體20之頂端21與該底端22係卡接於該套筒本體10之環槽112中,該徑向變形部23則凸出於該環槽112外。
是以,上述即為本發明一較佳實施例所提供之一種具彈性結合定位之套筒100之各部構件及其組裝方式的介紹,接著再將其使用特點說明如下:
當本發明具彈性結合定位之套筒100之驅動部11與一套筒扳手90套接時(如第八及第九圖所示),其原本外凸於該環槽112外之徑向變形部23,會受到該套筒扳手90之套孔內壁91所抵壓而向內產生徑向變形,即由該徑向變形部23之外側面231往內側面232方向進行內縮位移,使此時之徑向變形部23便積蓄一股朝該外側面231(即朝套孔內壁91)方向推出之彈性預力,使能由該徑向變形部23與該套筒扳手90之套孔內壁91產生暫時性地結合定位效果,以使本發明具彈性結合定位之套筒100與套筒扳手90間不會發生自行脫離之情事。
另外,由於本發明中彈性定位體20之徑向變形部23具有徑向變形之能力,因此設於該套筒本體10上之環槽112深度僅需極淺便可,如第九圖所示,使位於環槽112位置之套筒本體10厚度d與套筒本體10其他位置之厚度D相差無幾,而能確保整體之強度,以達到增進使用壽命之功效。
再者,雖然上述實施例中該徑向變形部23之外側面231為外凸圓弧面,而該徑向變形部23之內側面232為內凹圓弧面。但,實際上,如第十圖所示,該徑向變形部23之外側面233亦可為外凸錐面,而該徑向變形部23之內側面234則為內凹錐面。或,如第十一圖所示,該彈性定位體20除該頂端21、底端22與徑向變形部23外,更具有一連接於該頂端21與該徑向變形部23間之頂端平直段24及一連接於該底端22與該徑向變形部23間之底端平直段25;其皆可達到相同之功效。
其次,本發明中該彈性定位體20之徑向變形部23於進行徑向之位移變形時,該頂端21與該底端22間之距離亦會隨之改變。
以上所揭,僅為本發明所提供之較佳實施例而已,並非用以限制本發明之實施範圍,凡本技術領域內之相關技藝者根據本發明所為之均等變化,皆應屬本發明所涵蓋之範圍。In order to enable your reviewers to further understand and agree with the features and characteristics of the present invention, the following preferred embodiments are listed and illustrated with the drawings as follows:
Please refer to FIG. 6 to FIG. 9, which show a sleeve 100 with elastic coupling and positioning provided by a preferred embodiment of the present invention, which mainly includes a sleeve body 10 and an elastic positioning body 20, wherein:
Please refer to the sixth to ninth figures. The sleeve body 10 has a driving portion 11 and a turning portion 12 which is coaxially and integrally connected with the driving portion 11. The cross section of the outer portion of the driving portion 11 is hexagonal. The free end of the driving portion 11 has a driving hole 111 extending inward. In this embodiment, the driving hole 111 is a square hole. The driving portion 11 has a ring groove 112 on the outer peripheral surface. The free end has a turning hole 121 extending inward, the turning hole 121 is in communication with the driving hole 111, and the diameter of the turning hole 121 is larger than the driving hole 111. In this embodiment, the turning hole 121 is a hexagonal hole.
Please refer to the sixth to ninth figures. The elastic positioning body 20 is made of metal and has a C-shaped sheet shape, which can define a top end 21, a bottom end 22 located at the opposite end position of the top end, and a connection to A radial deformation part 23 between the top end 21 and the bottom end 22, the radial deformation part 23 can be elastically deformed in the radial direction by an external force; the top end 21 of the elastic positioning body 20 and the bottom end 22 are engaged with each other. In the ring groove 112 of the sleeve body 10, the radial deformation portion 23 protrudes out of the ring groove 112.
Therefore, the above is an introduction to the components and assembly methods of a sleeve 100 with elastic binding positioning provided by a preferred embodiment of the present invention, and then its use characteristics are described as follows:
When the driving part 11 of the sleeve 100 with elastic binding and positioning according to the present invention is sleeved with a sleeve wrench 90 (as shown in the eighth and ninth figures), the radial deformation that originally protrudes outside the ring groove 112 The part 23 is radially deformed inward by the inner wall 91 of the sleeve hole of the socket wrench 90, that is, the radially deformed part 23 is contracted and displaced toward the inner side 232 from the outer side 231, so that At this time, the radial deformation portion 23 accumulates an elastic pre-force that is pushed out in the direction of the outer surface 231 (that is, toward the inner wall of the sleeve hole 91), so that the sleeve formed by the radial deformation portion 23 and the socket wrench 90 can be set. The inner wall 91 of the hole produces a temporary combined positioning effect, so that the sleeve 100 and the sleeve wrench 90 of the present invention with the elastic combined positioning will not detach themselves.
In addition, since the radial deformation portion 23 of the elastic positioning body 20 in the present invention has the capability of radial deformation, the depth of the ring groove 112 provided on the sleeve body 10 only needs to be extremely shallow, as shown in the ninth figure The thickness d of the sleeve body 10 at the position of the ring groove 112 and the thickness D of other positions of the sleeve body 10 are almost the same, and the overall strength can be ensured to achieve the effect of improving the service life.
Furthermore, although the outer side surface 231 of the radial deformation portion 23 is a convex arc surface in the above embodiment, the inner side surface 232 of the radial deformation portion 23 is a concave arc surface. However, in fact, as shown in the tenth figure, the outer side surface 233 of the radial deformation portion 23 may be a convex convex cone surface, and the inner side surface 234 of the radial deformation portion 23 is a concave concave cone surface. Or, as shown in the eleventh figure, in addition to the top 21, the bottom 22, and the radial deformation portion 23, the elastic positioning body 20 further has a top end connected between the top 21 and the radial deformation 23. The straight section 24 and a straight section 25 at the bottom end connected between the bottom end 22 and the radial deformation portion 23 can achieve the same effect.
Secondly, in the present invention, when the radial deformation portion 23 of the elastic positioning body 20 undergoes radial displacement deformation, the distance between the top end 21 and the bottom end 22 will also change accordingly.
The above disclosure is only the preferred embodiments provided by the present invention, and is not intended to limit the scope of implementation of the present invention. Any equivalent changes made by those skilled in the art in accordance with the present invention should belong to the present invention. Coverage.
