以下僅以實施例說明本創作可能之實施態樣，然並非用以限制本創作所欲保護之範疇，合先敘明。The following only uses examples to illustrate the possible implementation of this creation, but it is not intended to limit the scope of this creation to be protected, which will be described first.

請參考圖1至圖8，其顯示本創作之一實施例，本創作之扭力轉接套筒包括一套筒單元1及一驅動單元4。Please refer to FIGS. 1 to 8, which show an embodiment of the creation. The torque adapter sleeve of the creation includes a sleeve unit 1 and a drive unit 4.

該套筒單元1包含有一本體2及一蓋體3，該本體2包含有一組接端21、一工作端22及一容室23，該組接端21設有一組接部211，該容室23貫通該工作端22，該蓋體3螺設於該工作端22，該蓋體3於背向該容室23之一外端面31凹設有至少二凹部33，該至少二凹部33供一手工具7插接，藉此組裝人員可透過該手工具7將該蓋體3組裝於該本體2，不僅操控便利且可避免組裝人員之手部髒汙、受傷。The sleeve unit 1 includes a body 2 and a cover 3. The body 2 includes a set of terminals 21, a working end 22 and a containing chamber 23. The set of connecting ends 21 is provided with a set of connecting portions 211. 23 passes through the working end 22, the cover 3 is screwed on the working end 22, the cover 3 is concavely provided with at least two concave portions 33 on an outer end surface 31 facing away from the chamber 23, and the at least two concave portions 33 are provided for one hand The tool 7 is inserted, so that the assembler can assemble the cover 3 to the body 2 through the hand tool 7, which not only facilitates manipulation but also prevents the hands of the assembler from being dirty and injured.

該驅動單元4包含有一驅動頭41及一扭力跳脫機構42，該扭力跳脫機構42容設於該容室23且抵靠於該蓋體3，該蓋體3之深度位置變化可以控制該扭力跳脫機構42之預壓扭力值，該驅動頭41連接該扭力跳脫機構42且穿設凸伸出該蓋體3，以便於帶動緊固件旋動。The driving unit 4 includes a driving head 41 and a torque tripping mechanism 42. The torque tripping mechanism 42 is accommodated in the chamber 23 and abuts against the cover 3. The change of the depth position of the cover 3 can control the The preload torque value of the torque tripping mechanism 42, the driving head 41 is connected to the torque tripping mechanism 42 and is protruded to protrude from the cover 3, so as to drive the fastener to rotate.

於本實施例中，透過該手工具7旋動該蓋體3時，不僅有上述優點外，輔助組裝人員更可以透過該手工具7之位置得知該蓋體3轉動圈數，進而確實地將該蓋體3組設至預定深度位置，使得所生產的該扭力轉接套筒具有較精密之裝配。舉例但不限於，該手工具7帶動該蓋體3轉動5圈之位置，即代表此次該扭力轉接套筒出廠時所對應的預壓扭力值，組裝人員僅需牢記轉動圈數即可，有助於簡化組裝過程及快速教學。In this embodiment, when the cover 3 is rotated through the hand tool 7, in addition to the above advantages, the auxiliary assembler can also know the number of rotations of the cover 3 through the position of the hand tool 7, and then reliably The cover body 3 is set to a predetermined depth position, so that the torque adapter sleeve produced has a more precise assembly. For example, but not limited to, the position where the hand tool 7 drives the cover body 3 to rotate 5 times, which represents the corresponding pre-compression torque value of the torque adapter sleeve at the factory, the assembler only needs to remember the number of rotations , Help to simplify the assembly process and fast teaching.

較佳地，該至少二凹部33係以該驅動頭41為中心地呈等間隔角度分布於該外端面31，使得該手工具7能對稱地插接至少二該凹部33，以穩定地帶動該蓋體3轉動。於本實施例中，該至少二凹部33之數量為四。Preferably, the at least two recesses 33 are distributed on the outer end surface 31 at an equal angle with the driving head 41 as the center, so that the hand tool 7 can be symmetrically inserted into the at least two recesses 33 to stably drive the The cover 3 rotates. In this embodiment, the number of the at least two concave portions 33 is four.

另一較佳地，該套筒單元1另包含有至少一定位機構5，該定位機構5包含有一貫孔51及一定位件52，該貫孔51徑向地貫通該本體2之工作端22，該定位件52穿設過該貫孔51以抵接定位住該蓋體3，如此一來，出廠後的該扭力轉接套筒之安全扭力跳脫之扭力值、內部結構配置不會被使用者非預期更改，以確保出產品質、減少售後糾紛。於本實施例中，該至少一定位機構5之數量為二，且係以該驅動頭41為軸而呈對稱配置，以均勻地提供定位作用力予該蓋體3。Preferably, the sleeve unit 1 further includes at least one positioning mechanism 5. The positioning mechanism 5 includes a through hole 51 and a positioning member 52. The through hole 51 radially penetrates the working end 22 of the body 2 , The positioning member 52 is penetrated through the through hole 51 to abut the positioning of the cover body 3, so that the torsion value and internal structure configuration of the safe torsion tripping of the torsion adapter sleeve after delivery will not be affected Unexpected changes by users to ensure product quality and reduce after-sales disputes. In this embodiment, the number of the at least one positioning mechanism 5 is two, and the driving head 41 is used as the axis in a symmetrical configuration to provide a positioning force to the cover 3 uniformly.

具體來說，該扭力跳脫機構42包含有一彈性組件43、一第一卡掣件44及一第二卡掣件45，該第一卡掣件44定位於該容室23且包含有一第一卡齒部441，該第二卡掣件45可選擇性相對該第一卡掣件44轉動地容設於該容室23，該第二卡掣件45包含有一第二卡齒部451且連接該驅動頭41而成同轉動關係，該彈性組件43彈抵於該蓋體3與該第二卡掣件45之間，該彈性組件43迫使該第二卡齒部451常態地嚙合於該第一卡齒部441。於本實施例中，該驅動頭41與該第二卡掣件45係一體成型，以減少元件數量、簡化組裝過程。Specifically, the torque tripping mechanism 42 includes an elastic element 43, a first latching member 44 and a second latching member 45, the first latching member 44 is positioned in the chamber 23 and includes a first The latching portion 441, the second latching member 45 can be selectively accommodated in the chamber 23 relative to the first latching member 44, and the second latching member 45 includes a second latching portion 451 and connected The driving head 41 is in the same rotational relationship. The elastic element 43 springs between the cover 3 and the second latch 45. The elastic element 43 forces the second latch portion 451 to normally mesh with the first latch一卡齿部441. In this embodiment, the driving head 41 and the second catch 45 are integrally formed to reduce the number of components and simplify the assembly process.

更具體來說，當該驅動頭41旋緊緊固件所產生的扭力矩數值未達到該彈性組件43所提供之彈力前，該第一卡齒部441與該第二卡齒部451皆會保持嚙合狀態；反之，當產生的扭力值大於彈力時，該第一卡齒部441與該第二卡齒部451會產生跳齒現象，使得該第二卡掣件45會相對該第一卡掣件44轉動，以確保緊固件之結構健全。More specifically, when the torque value generated by the driving head 41 tightening the fastener does not reach the elastic force provided by the elastic element 43, both the first clamping tooth portion 441 and the second clamping tooth portion 451 will remain Meshing state; conversely, when the generated torque value is greater than the elastic force, the first latching portion 441 and the second latching portion 451 will produce a tooth jump phenomenon, so that the second latch 45 will be relative to the first latch The piece 44 rotates to ensure the sound structure of the fastener.

可以理解的是，緊固件之結構會受損大都係發生在使用者過度旋緊，換言之，於旋鬆緊固件過程中較不會有毀損問題。因此，於本實施例中，該第一卡齒部441與該第二卡齒部451分別係為單向齒結構，亦即該第一卡掣件44與該第二卡掣件45僅能沿單一方向(旋緊)可選擇性地跳齒而相對轉動，而反向旋動時(旋鬆)該第一卡掣件44與該第二卡掣件45則係保持同轉動關係。It can be understood that most of the damage to the structure of the fastener occurs when the user tightens excessively. In other words, there is less damage during the loosening of the fastener. Therefore, in this embodiment, the first latching portion 441 and the second latching portion 451 are respectively one-way tooth structure, that is, the first latching member 44 and the second latching member 45 can only In a single direction (tightening), the teeth can be selectively jumped to rotate relatively, while in the reverse rotation (unscrewing), the first locking member 44 and the second locking member 45 maintain the same rotation relationship.

值得一提的是，該彈性組件43包含有複數個相連接之盤型彈簧431，該複數盤型彈簧431套接於該驅動頭41；其中，一該盤型彈簧431抵靠於該第二卡掣件45，另一該盤型彈簧431抵靠於該蓋體3。該彈性組件43選用該盤型彈簧431可以大幅縮減壓縮行程並提升整個負荷能力，進而讓該扭力轉接套筒具有體積縮小化、重量輕量化、安全性提升之優點。並且，透過正反裝配可以快速改變該彈性組件43之彈簧係數，有利於生產者快速變更設定。舉例來說，當該複數盤型彈簧431係採用反向堆疊之配置時，其壓縮行程與該複數盤型彈簧431之數量成倍數正比，利於設計者規劃尺寸、計算相關數據。It is worth mentioning that the elastic component 43 includes a plurality of disc springs 431 connected to each other, and the plurality of disc springs 431 are sleeved on the driving head 41; wherein, one disc spring 431 abuts against the second The locking member 45 and the other disc spring 431 abut against the cover 3. The use of the disc spring 431 for the elastic component 43 can greatly reduce the compression stroke and increase the entire load capacity, thereby allowing the torque adapter sleeve to have the advantages of reduced volume, light weight, and improved safety. Moreover, the spring coefficient of the elastic component 43 can be quickly changed through the front and back assembly, which is helpful for the manufacturer to quickly change the setting. For example, when the plural disc springs 431 are in a reverse stack configuration, the compression stroke is proportional to the number of the plural disc springs 431, which is beneficial for the designer to plan the dimensions and calculate related data.

要特別說明的是，由於該複數盤型彈簧431具有上述所提壓縮行程短之特性，故其壓縮行程無需過長即可滿足日常生活、一般工廠使用。具體地說，該彈性組件43(該複數盤型彈簧431)係彈抵於該蓋體3之一內端面32與該第二卡掣件45之一彈抵面452之間；於該本體2之軸向24上，該內端面32與該彈抵面452之距離定義為一第一尺寸61，該第一卡掣件44與該第二卡掣件45相互嚙合之整體厚度定義為一第二尺寸62，該第二尺寸62係大於該第一尺寸61。It should be particularly noted that, since the plural disc springs 431 have the above-mentioned short compression stroke characteristics, the compression stroke need not be too long to satisfy daily life and general factory use. Specifically, the elastic component 43 (the plurality of disc springs 431) is resiliently pressed between an inner end surface 32 of the cover 3 and a resiliently facing surface 452 of the second latch 45; at the body 2 In the axial direction 24, the distance between the inner end surface 32 and the resilient contact surface 452 is defined as a first dimension 61, and the overall thickness of the first engaging member 44 and the second engaging member 45 engaged with each other is defined as a first Two sizes 62, the second size 62 is larger than the first size 61.

於本實施例中，該複數盤型彈簧431之數量為四且採用反向堆疊，該第一尺寸61與該第二尺寸62之比值介於0.6至0.8之間。並且，於該本體2之軸向24上，該本體2之長度定義為一第三尺寸63，該第一尺寸61與該第三尺寸63之比值介於0.15至0.4之間。此外，各該盤型彈簧431之一內環面432至該驅動頭41之一外環面411之間界定有一間隙46，該間隙46之距離係介於0.4mm至0.8mm之間，以提供足夠變形裕度予各該盤型彈簧431。In the present embodiment, the number of the plurality of disc springs 431 is four and the reverse stacking is adopted. The ratio of the first size 61 to the second size 62 is between 0.6 and 0.8. Moreover, in the axial direction 24 of the body 2, the length of the body 2 is defined as a third dimension 63, and the ratio of the first dimension 61 to the third dimension 63 is between 0.15 and 0.4. In addition, a gap 46 is defined between an inner ring surface 432 of each disc spring 431 and an outer ring surface 411 of the driving head 41, and the distance of the gap 46 is between 0.4 mm and 0.8 mm to provide A sufficient deformation margin is given to each of the coil springs 431.

綜上，本創作之扭力轉接套筒，蓋體凹設有至少二凹部，可供手工具插接旋動，進而能有效簡化組裝難度、易於教導組裝人員、提升組裝精度等優點；並且，透過盤型彈簧的設計可以大幅縮減體積、重量輕量化等優點。In summary, the torque adapter sleeve of this creation has at least two recesses in the cover body, which can be inserted and rotated by hand tools, which can effectively simplify the difficulty of assembly, easy to teach assembly personnel, and improve assembly accuracy; and, Through the design of the disc spring, the advantages of volume reduction and light weight can be greatly reduced.
