Abstract
本發明包含一種螺旋緊固裝置，其由一旋轉座及一衝擊件以一螺線段螺接組成，前述旋轉座對應位於旋轉軸心，且旋轉座限制衝擊件在螺線段上旋動，而衝擊件具有的重量與動能會提供一個環繞旋轉軸心的單向切線衝擊力。藉此，本發明可提供在旋鬆時增加一額外切線衝擊力，而在最小佔用空間的條件下達成提供瞬間旋鬆扭力的便利效果。 The invention comprises a screw fastening device, which is composed of a rotating seat and an impact member which are screwed by a spiral segment. The rotating seat is correspondingly located at the rotating axis, and the rotating seat limits the impacting member to rotate on the spiral segment, and the impact The weight and kinetic energy of the piece provides a one-way tangential impact force around the axis of rotation. Thereby, the present invention can provide an additional tangential impact force when unscrewing, and a convenient effect of providing an instantaneous unscrewing torque under the condition of minimum occupied space.
Description
本發明是有關於一種緊固裝置及其應用方法，且特別是有關於一種應用在旋轉緊固作業時提供瞬間旋鬆扭力的螺旋緊固裝置及其應用方法。 The present invention relates to a fastening device and a method of applying the same, and more particularly to a screw fastening device for applying an instantaneous unscrewing torque during a rotary fastening operation and a method of applying the same.
近年來手工具產品逐漸朝向輕便化發展，因此各種旋轉緊固工具也需對應市場需求輕量化及小型化。然而對於旋轉鬆脫作業來說，無論是旋轉螺絲、螺帽或其他緊定元件的鬆脫時，旋轉鬆脫需要較大的瞬間扭力對抗長期緊固的鏽蝕或變形咬死，方能確保正確鬆脫拆除。習知的緊固裝置如電動扳手配合套筒進行緊固時，受限於電動扳手本身的馬達具有固定的扭力上限，所以現有市場上的電動扳手難以同時在滿足小型化時，又達成保持較佳鬆脫效果的需求。 In recent years, hand tool products have gradually developed toward lighter weight, so various rotary fastening tools are also required to be lighter and smaller in size in response to market demands. However, for the loose release operation, whether the rotating screw, the nut or other tightening elements are loose, the loose rotation requires a large momentary torque to resist the long-term tightening of the rust or deformation, so as to ensure the correct Loose and removed. When a conventional fastening device such as an electric wrench is used for fastening with a sleeve, the motor of the electric wrench itself is limited to have a fixed upper limit of the torque, so that the electric wrench on the existing market is difficult to meet the miniaturization at the same time. Jiasong off the demand for the effect.
另一方面，雖然氣動扳手可以產生較高扭力來達成較高鬆脫力量的需求，但是習用氣動扳手需要配合氣泵及各自的管線，加上氣動扳手本身都具有較大的氣缸，故氣動扳手體積難以縮小。前述問題也令習用的氣動扳手無法符合輕量化及小型化的發展趨勢。 On the other hand, although the pneumatic wrench can generate higher torque to achieve higher release force, the conventional pneumatic wrench needs to match the air pump and the respective pipeline, and the pneumatic wrench itself has a large cylinder, so the air wrench volume It is difficult to shrink. The aforementioned problems also make the conventional pneumatic wrench unable to meet the trend of light weight and miniaturization.
對此，市面上已有開發出類似TWI520817的一種動力工具之扭力控制機構與扭力控制方法，其大體上包含馬達、變速齒輪組、傳動軸、打擊組(如出力軸、擊座)、控制系統等構件，變速齒輪組係連接於馬達一端，用以改變馬達輸出之旋轉動力，傳動軸係連接變速齒輪組，出力軸係以可旋轉之方式同軸接設於傳動軸一端，可供連接螺絲起子、套筒等工作接頭，擊座係套設於傳動軸上，而可沿傳動軸之軸向於一打擊及釋放位置間往復位移，出力軸之一端與擊座一端分別對應突設有擊塊，用以當擊座移動至打擊位置時，各擊塊可對應抵接、打擊，使出力軸可受擊打而旋轉產生較大的瞬時扭力，用以進行鬆脫螺絲或螺帽等動作。 In this regard, a torque control mechanism and a torque control method for developing a power tool similar to TWI520817 have been developed, which generally include a motor, a shifting gear set, a drive shaft, a strike group (such as a power output shaft, a seat block), and a control system. The transmission gear set is connected to one end of the motor for changing the rotational power of the motor output, the transmission shaft is coupled to the shift gear set, and the output shaft is coaxially connected to one end of the drive shaft in a rotatable manner for connecting the screwdriver The working joint of the sleeve and the sleeve is sleeved on the transmission shaft, and can be reciprocally displaced along a direction of the transmission shaft at a striking and releasing position, and one end of the output shaft and one end of the striking shaft respectively have a striking block. When the seat is moved to the striking position, each striking block can be correspondingly abutted and struck, so that the output shaft can be rotated and struck to generate a large instantaneous torque for loosening the screw or the nut.
前述習用專利技術雖然可以達成加大緊固扭力的需求，然而其結構複雜且配套機構繁多，不僅無法配合各種類加工機具的操作，且仍然不符合市場需求的輕量化及小型化特性。 Although the above-mentioned conventional patent technology can achieve the demand for increasing the tightening torque, the structure is complicated and the supporting mechanism is numerous, and it is not only unable to cooperate with the operation of various types of processing tools, but still does not meet the market demand for light weight and miniaturization characteristics.
另有美國專利公開號US20120255749A1案，提出一種一體成形的套筒，在此套筒上一體成形出環狀的重力環件。此種設計雖然結構已簡化，但是仍然沒有快速拆卸重力構件的功能；此外，此習用套筒上一體成形之重力環件不但製造困難，且前述習用在緊固作業時會因瞬間力量過度而破壞加工物件，其一體式的設計也會浪費較多的驅動能源。 In addition, in U.S. Patent Publication No. US20120255749A1, an integrally formed sleeve is proposed in which an annular gravitational ring member is integrally formed. Although the design of the design has been simplified, there is still no function of quickly disassembling the gravity member; in addition, the gravity ring member integrally formed on the conventional sleeve is not only difficult to manufacture, but also the above-mentioned conventional use may cause damage due to excessive moment force during fastening work. The integrated design of the processed object also wastes more driving energy.
依據上述內容，如何能將旋轉緊固裝置的輕量化、小型化及緊固效果進行良好整合，係為現今手工具開發者及工具機廠商皆十分期待解決的一項重要課題。 According to the above, how to integrate the lightweight, miniaturization and fastening effects of the rotary fastening device is an important issue that is expected to be solved by today's hand tool developers and machine tool manufacturers.
因此，本發明提供一種可以提供瞬間旋鬆扭力的螺旋緊固裝置及其應用方式，利用衝擊件在旋轉座上的螺旋轉動及卡掣的運動，能夠使衝擊件產生環繞旋轉軸心的一單向切線衝擊力，單向切線衝擊力瞬間讓衝擊件連動旋轉座一瞬間旋鬆扭力，藉此增加此瞬間旋鬆扭力帶動一待旋動件進行鬆脫作業。 Therefore, the present invention provides a screw fastening device capable of providing an instantaneous unscrewing torque and an application thereof. The spiral rotation of the impact member on the rotary seat and the movement of the clicker enable the impact member to generate a single rotation around the axis of rotation. The tangential impact force, the one-way tangential impact force instantaneously causes the impact member to rotate the rotating seat for a moment to loosen the torsion force, thereby increasing the instantaneous unscrewing torque to drive the rotating member to be loosened.
依據本發明結構態樣提供一種螺旋緊固裝置，其螺旋緊固裝置銜接在一衝擊驅動工具與一待旋動件之間。螺旋緊固裝置包含有一旋轉座及一衝擊件。旋轉座沿一旋轉軸心旋轉，且旋轉座具有一驅動端及一緊固端，驅動端可拆卸地連接衝擊驅動工具，而緊固端則可拆卸地連結帶動待旋動件，旋轉座上具有一螺線段，螺線段具有一末端。衝擊件可樞轉地螺設在螺線段上，而旋轉座於一第一旋轉方向被待旋動件限制而未旋轉時，衝擊件被衝擊驅動工具之一衝擊力帶動，令衝擊件被衝擊驅動工具帶動而旋動至螺線段的末端，使衝擊件卡掣末端增加環繞旋轉軸心的一單向切線衝擊力。另一方面使用者也可以先讓衝擊件旋動至螺線段的末端上緊，再直接令衝擊件被衝擊驅動工具增加一瞬間旋鬆扭力。 According to a structural aspect of the present invention, a screw fastening device is provided, the screw fastening device being coupled between an impact driving tool and a to-be-swivel member. The screw fastening device comprises a rotating seat and an impact member. The rotating seat rotates along a rotating shaft, and the rotating base has a driving end and a fastening end, the driving end is detachably connected to the impact driving tool, and the fastening end is detachably coupled to drive the rotating member, the rotating seat There is a spiral segment, and the spiral segment has an end. The impact member is pivotally screwed on the spiral segment, and when the rotary seat is restricted by the to-be-rotated member in a first rotational direction without being rotated, the impact member is driven by an impact force of the impact driving tool, so that the impact member is impacted. The driving tool is driven to rotate to the end of the spiral segment, so that the end of the impact member is increased by a one-way tangential impact force around the rotation axis. On the other hand, the user can also first rotate the impact member to the end of the spiral segment, and then directly increase the impact of the impact member by the impact driving tool.
藉由本發明結構可以在旋脫待旋動件時，增加瞬間旋鬆扭力令待旋動件被順利旋轉脫出，也不再困擾於螺 絲、螺帽或螺桿長期緊固的鏽蝕或變形咬死。此外，本發明結構簡單、不佔空間又可以依需求拆卸。因此，本發明藉此實施方式不但可以增加瞬間旋鬆扭力，且同步達成小型化、輕量化及增加配搭變化的產業需求。 According to the structure of the present invention, when the screw to be rotated is rotated, the momentary loosening torque is increased, so that the to-be-rotated member is smoothly rotated and released, and the screw is no longer troubled. The wire, nut or screw is rusted or deformed by long-term fastening. In addition, the invention has a simple structure, does not occupy space, and can be disassembled according to requirements. Therefore, the embodiment of the present invention can not only increase the instantaneous unscrewing torque, but also achieve the industrial demand for miniaturization, weight reduction, and increase of the matching change.
前述實施態樣的其他實施例如後；前述螺線段可以為右旋螺線(而待旋動件則為向左旋鬆)或左旋螺線(而待旋動件則為向右旋鬆)，且前述第一旋轉方向為向左旋鬆方向或向右旋鬆方向。前述螺線段上可設有一防旋脫裝置。而前述防旋脫裝置為埋設於旋轉座表面的一復位簧件。前述衝擊件外形可以為圓環狀、三角狀、放射狀、凸出桿狀或凸出塊狀。而前述螺線段與驅動端的距離可以小於螺線段與緊固端的距離，方能有效傳導扭力。另可以在旋轉座上設有一扭力偵測單元，以利偵測有效扭力值。 Other implementations of the foregoing embodiments may be followed by the following; the aforementioned spiral segment may be a right-handed spiral (and the left-handed screw is rotated to the left) or a left-handed spiral (and the right-to-spin is to be rotated). The aforementioned first direction of rotation is a leftward unscrewing direction or a rightward unscrewing direction. An anti-rotation device may be disposed on the spiral segment. The anti-rotation device is a return spring embedded in the surface of the rotating base. The shape of the impact member may be an annular shape, a triangular shape, a radial shape, a convex rod shape or a convex block shape. The distance between the spiral segment and the driving end may be smaller than the distance between the spiral segment and the fastening end to effectively transmit the torque. In addition, a torque detecting unit can be arranged on the rotating base to detect the effective torque value.
依據本發明方法態樣提供一種螺旋緊固裝置的應用方法，其應用於前述螺旋緊固裝置，螺旋緊固裝置的應用方法包含一旋鬆前步驟及一旋鬆帶動步驟。旋鬆前步驟中以旋轉座接收衝擊驅動工具之衝擊力，但旋轉座於第一旋轉方向(為旋鬆方向)被待旋動件限制而未旋轉。旋鬆帶動步驟中，衝擊件接收衝擊驅動工具之衝擊力，令衝擊件被衝擊驅動工具帶動而旋動至螺線段的末端，使衝擊件卡掣末端產生環繞旋轉軸心的一單向切線衝擊力，單向切線衝擊力瞬間讓衝擊件連動旋轉座增加一瞬間旋鬆扭力，藉此帶動待旋動件。藉此，本發明方法可以在旋脫時產生瞬間旋鬆扭力令待旋動件被順利旋轉脫出。另一方面使用者也可以先讓衝擊件 旋動至螺線段的末端上緊，再直接令衝擊件被衝擊驅動工具增加一瞬間旋鬆扭力。 According to the method aspect of the present invention, a method for applying a screw fastening device is provided, which is applied to the aforementioned screw fastening device, and the application method of the screw fastening device comprises a pre-spinning step and a unscrewing step. In the pre-screwing step, the impact force of the impact driving tool is received by the rotating seat, but the rotating seat is restricted by the to-be-rotated member without being rotated in the first rotating direction (in the unscrewing direction). In the unscrewing step, the impact member receives the impact force of the impact driving tool, so that the impact member is driven by the impact driving tool and is rotated to the end of the spiral segment, so that the end of the impacting member has a one-way tangential impact around the rotating axis. The force, the one-way tangential impact force instantly causes the impact member to interlock with the rotating seat to increase the moment of unscrewing torque, thereby driving the to-be-swiveled member. Thereby, the method of the invention can generate an instantaneous unwinding torque when the screw is released, so that the to-be-rotated member is smoothly rotated and disengaged. On the other hand, the user can also let the impact piece first Rotate to the end of the spiral segment and tighten the impact member directly by the impact drive tool for a moment to loosen the torque.
藉此方法可以另包含一旋緊帶動步驟及一衝擊件不連動步驟；旋緊帶動步驟中，旋轉座被衝擊驅動工具帶動於第二旋轉方向旋轉(為旋緊方向)，且旋轉座於第二旋轉方向帶動待旋動件旋緊。衝擊件不連動步驟中，旋轉座於第二旋轉方向帶動待旋動件旋轉時，衝擊件同時接收衝擊驅動工具之衝擊力而朝第二旋轉方向旋動，且令衝擊件遠離螺線段的末端，致使衝擊件保持不連動旋轉座。藉此，本發明方法可以避免旋緊時產生瞬間加大扭力令待旋動件過度鎖緊。The method may further include a tightening driving step and an impact member non-coupling step; in the tightening driving step, the rotating base is driven by the impact driving tool to rotate in the second rotating direction (in the tightening direction), and the rotating seat is in the The two directions of rotation drive the screw to be screwed. In the step of non-coupling of the impacting member, when the rotating seat drives the rotating member to rotate in the second rotating direction, the impacting member simultaneously receives the impact force of the impact driving tool and rotates in the second rotating direction, and the impacting member is away from the end of the spiral segment. , causing the impact member to remain uncoupled to the rotating seat. Thereby, the method of the invention can avoid the momentary increase of the torsion force when the screwing is tightened, so that the to-be-rotated member is excessively locked.

According to the structural aspect of the present invention, a screw fastening device 100 is provided which is disposed between an impact driving tool 200 and a to-be-swivel member 300. The screw fastening device 100 includes a rotating base 110, an impact member 120 and an anti-rotation device 130.
旋轉座110呈一圓桿狀，在旋轉座110二端分別成形出一緊固端111及一驅動端112。前述緊固端111為內六角孔用以可拆卸地連結帶動待旋動件300(例如：螺絲、螺帽及螺桿等元件)。前述驅動端112為具有一鋼珠1121定位功能的內方孔，藉由驅動端112可供衝擊驅動工具200(例如：電動扳手、氣動扳手)。旋轉座110沿一旋轉軸心X旋轉。旋轉座110上具有一螺線段113，螺線段113為右旋螺線，另在螺線段113的靠近驅動端112的最外端具有一末端1131。而前述螺線段113與驅動端112的距離小於螺線段113與緊固端111的距離，藉以有效傳導扭力。另可以在旋轉座110內埋設有一扭力偵測單元(未圖示)，以利偵測有效扭力值。 The rotating base 110 has a round rod shape, and a fastening end 111 and a driving end 112 are respectively formed at two ends of the rotating base 110. The fastening end 111 is a hexagonal hole for detachably connecting the component to be rotated 300 (for example, an element such as a screw, a nut and a screw). The driving end 112 is an inner hole having a positioning function of the steel ball 1121, and the driving end 112 can be used to drive the tool 200 (for example, an electric wrench or an air wrench). The rotary base 110 rotates along a rotational axis X. The rotating base 110 has a spiral segment 113, the spiral segment 113 is a right-handed spiral, and the outer end of the spiral segment 113 near the driving end 112 has an end 1131. The distance between the spiral segment 113 and the driving end 112 is smaller than the distance between the spiral segment 113 and the fastening end 111, thereby effectively transmitting the torque. A torque detecting unit (not shown) may be embedded in the rotating base 110 to detect an effective torque value.
衝擊件120為一環形體，且衝擊件120外側形狀一體製作有三個箭頭形凸出桿121，利用凸出桿121的重量旋轉位移時形成慣性動能。在衝擊件120中央具有一樞穿孔122，且於樞穿孔122內側完整環繞製作內螺紋1221，樞穿孔122的內螺紋1221相對應螺設在前述旋轉座110的螺線段113上。前述內螺紋1221與螺線段113的螺旋旋轉動作受到末端1131限制卡掣。且螺線段113的螺牙數多於內螺紋1221的螺牙數。 The impact member 120 is an annular body, and the outer shape of the impact member 120 is integrally formed with three arrow-shaped protruding rods 121, and the inertia kinetic energy is formed by the rotational displacement of the weight of the protruding rod 121. A pivot hole 122 is formed in the center of the impact member 120, and the inner thread 1221 is completely formed on the inner side of the pivot hole 122. The internal thread 1221 of the pivot hole 122 is correspondingly screwed on the spiral segment 113 of the rotary base 110. The spiral rotation of the aforementioned internal thread 1221 and the spiral segment 113 is restricted by the end 1131. Moreover, the number of threads of the spiral segment 113 is larger than the number of threads of the internal thread 1221.
防旋脫裝置130為一凸出卡簧，且被埋設在前述螺線段113上。而前述防旋脫裝置130埋設於末端1131的相對一端(衝擊件120安裝螺設的進入端)，此防旋脫裝置130具有可以昇降復位的凸出部131，此凸出部131初步抵擋內螺紋1221在運作過程之中鬆脫，且可昇降復位的凸出部131讓衝擊件120順暢螺設進入螺線段113。 The anti-rotation device 130 is a protruding circlip and is embedded on the aforementioned spiral segment 113. The anti-rotation device 130 is embedded in the opposite end of the end 1131 (the entrance end of the impact member 120 is screwed), and the anti-rotation device 130 has a protrusion 131 that can be lifted and lowered, and the protrusion 131 is initially resisted. The thread 1221 is loosened during operation, and the protrusion 131 that can be lifted and lowered allows the impact member 120 to be smoothly screwed into the spiral segment 113.
再請參閱第5A圖、第3圖、第4圖及第6圖，第5A圖是本發明鬆脫操作示意圖，而第6圖則繪示方法步驟流程圖。本發明方法態樣提供一種螺旋緊固裝置的應用方法400，其應用於前述螺旋緊固裝置100，螺旋緊固裝置100的應用方法400包含一旋鬆前步驟410及一旋鬆帶動步驟420。 Referring to FIG. 5A, FIG. 3, FIG. 4 and FIG. 6 , FIG. 5A is a schematic diagram of the loosening operation of the present invention, and FIG. 6 is a flow chart of the method steps. The method of the present invention provides a method 400 for applying a screw fastening device to the aforementioned screw fastening device 100. The method 400 for applying the screw fastening device 100 includes a pre-spinning step 410 and a unscrewing step 420.
旋鬆前步驟410中以旋轉座110接收衝擊驅動 工具200之衝擊力，此衝擊力為衝擊驅動工具200內一擊錘(習知一般技術且未圖示)的瞬時打擊，衝擊驅動工具200的出力軸藉由擊錘間歇擊打而產生向左旋轉扭力。雖然前述緊固端111可連結帶動待旋動件300，但當待旋動件300被長期緊固的鏽蝕或變形咬死，則但旋轉座110於第一旋轉方向(為旋鬆方向)會被待旋動件300限制卡掣而未能旋轉帶動。 In the pre-screwing step 410, the rotating seat 110 receives the impact drive The impact force of the tool 200 is a momentary impact of a hammer (not known in the prior art and not shown) in the impact driving tool 200. The output shaft of the impact driving tool 200 is rotated to the left by intermittently hitting the hammer. Turn torque. Although the aforementioned fastening end 111 can be coupled to drive the to-be-swimmed member 300, when the to-be-swildered member 300 is sewn by rust or deformation of long-term fastening, the rotating base 110 will be in the first rotational direction (in the unscrewing direction). The card to be rotated 300 is restricted from being jammed and cannot be rotated.
旋鬆帶動步驟420中，雖然旋轉座110未能旋轉，然而衝擊件120仍可間接接收衝擊驅動工具200之間歇衝擊力，令衝擊件120被衝擊驅動工具200帶動而快速向左旋動，隨著箭頭形凸出桿121旋甩的加速慣性，衝擊件120會以內螺紋1221在右旋螺線段113上沿旋轉軸心X位移，直到衝擊件120卡掣末端1131產生環繞旋轉軸心X的一單向切線衝擊力F，同時衝擊件120的單向切線衝擊力F瞬間連動旋轉座110產生一瞬間旋鬆扭力Y(即為慣性)，藉此瞬間旋鬆扭力Y帶動待旋動件300鬆脫。藉此，本發明方法可以在旋脫時產生瞬間旋鬆扭力Y令待旋動件300被順利旋轉脫出。 In the unscrewing step 420, although the rotating base 110 fails to rotate, the impacting member 120 can indirectly receive the intermittent impact force of the impact driving tool 200, so that the impacting member 120 is driven by the impact driving tool 200 to quickly rotate to the left. The acceleration inertia of the arrow-shaped protruding rod 121 is rotated, and the impact member 120 is displaced along the rotation axis X by the internal thread 1221 on the right-handed spiral segment 113 until the impact member 120 is engaged with the end 1131 to generate a single rotation around the rotation axis X. The tangential impact force F, and the one-way tangential impact force F of the impact member 120 instantaneously rotates the rotary seat 110 to generate an instantaneous unscrewing torque Y (ie, inertia), thereby instantaneously loosening the torque Y to drive the to-be-swivel member 300 to be loose. . Thereby, the method of the present invention can generate an instantaneous unscrewing torque Y when the screw is released, so that the to-be-rotated member 300 is smoothly rotated and disengaged.
請參閱第5B圖，第5B圖是繪示本發明鎖緊操作示意圖。本發明方法可以另包含一旋緊帶動步驟及一衝擊件120不連動步驟。在旋緊帶動步驟中，旋轉座110被衝擊驅動工具200帶動於第二旋轉方向旋轉(為旋緊方向)，且旋轉座110於第二旋轉方向帶動待旋動件300向右旋緊。而衝擊件120不連動步驟中，旋轉座110於第二旋轉方向帶動待旋動件300向右旋轉時，衝擊件120同時接收衝擊驅動工具 200之間歇衝擊力而朝第二旋轉方向旋動(向右)，且令衝擊件120隨著箭頭形凸出桿121向右旋甩的加速慣性快速旋轉，此時衝擊件120右旋速度高於旋轉座110右旋速度，因此衝擊件120會間歇遠離螺線段113的末端1131，致使衝擊件120保持不連動旋轉座110的狀態。藉此，本發明方法可以避免旋緊時產生瞬間加大扭力，也有效避免待旋動件300過度鎖緊的狀況。 Please refer to FIG. 5B, and FIG. 5B is a schematic view showing the locking operation of the present invention. The method of the present invention may further comprise a step of driving and a step of non-coupling of the impact member 120. In the step of tightening the driving, the rotating base 110 is rotated by the impact driving tool 200 in the second rotating direction (in the tightening direction), and the rotating base 110 drives the rotating member 300 to be screwed to the right in the second rotating direction. In the non-coupling step of the impacting member 120, when the rotating base 110 drives the rotating member 300 to rotate to the right in the second rotating direction, the impacting member 120 simultaneously receives the impact driving tool. The intermittent impact force of 200 is rotated in the second rotation direction (to the right), and the impact member 120 is rapidly rotated with the acceleration inertia of the arrow-shaped protruding rod 121 rotating to the right, and the impact member 120 has a high right-hand rotation speed. The rotary seat 110 rotates rightward, so that the impact member 120 intermittently moves away from the end 1131 of the spiral segment 113, so that the impact member 120 remains in a state of not interlocking with the rotary base 110. Thereby, the method of the invention can avoid the momentary increase of the torsion force when tightening, and also effectively avoid the situation that the rotary member 300 is excessively locked.
值得一提的是，前述的螺線段也可以為左旋，而待旋動件則為一反向螺紋螺件，且前述第一旋轉方向為向右旋鬆方向，故本發明同樣適用於反向螺紋螺件的操作。 It is worth mentioning that the aforementioned spiral segment can also be left-handed, and the to-be-swivel member is a reverse threaded screw member, and the first rotation direction is a rightward rotation direction, so the invention is equally applicable to the reverse direction. The operation of the threaded screw.
最後，請參閱第7圖，第7圖是繪示本發明的另一實施例之平面剖視圖，此實施例與前述實施方式相同之處不多作贅述。此實施例的防旋脫裝置130A包含二鋼珠131A及二復位彈簧132A，且復位彈簧132A及鋼珠131A依序被埋設在前述旋轉座110的螺線段113上。而前述防旋脫裝置130A的鋼珠131A可退縮地凸起於末端1131的相對端(未編號)旁，以此防旋脫裝置130A可以昇降復位的鋼珠131A初步抵擋衝擊件120的內螺紋1221，以避免衝擊件120在運作過程之中鬆脫，且可昇降復位的鋼珠131A容許衝擊件120順暢螺設進入螺線段113。 Finally, please refer to FIG. 7. FIG. 7 is a plan sectional view showing another embodiment of the present invention, and the embodiment is not described in detail in the same manner as the foregoing embodiment. The anti-rotation device 130A of this embodiment includes two steel balls 131A and two return springs 132A, and the return springs 132A and the steel balls 131A are sequentially embedded on the spiral segments 113 of the rotary base 110. The steel ball 131A of the anti-rotation device 130A is retractably protruded beside the opposite end (not numbered) of the end 1131, so that the anti-screwing device 130A can vertically lift the reset steel ball 131A to initially resist the internal thread 1221 of the impact member 120, In order to prevent the impact member 120 from being loosened during operation, the liftable and retractable steel ball 131A allows the impact member 120 to be smoothly screwed into the spiral segment 113.
藉由前述實施方式及實施例可得知，本發明所提出之螺旋緊固裝置及其應用方式，可以整合鬆脫增加扭力與旋緊不加扭力之雙重目的。藉由本發明結構可以在旋脫時產生瞬間旋鬆扭力令待旋動件被順利旋轉脫出，也不再困擾於螺絲、螺帽或螺桿長期緊固的鏽蝕或變形咬死。同時又不會在上緊待旋動件產生過度旋緊。此外，本發明結構簡單、不佔空間又可以依需求拆卸。因此，本發明藉此實施方式不但可以產生瞬間旋鬆扭力，且同步達成小型化、輕量化及增加配搭變化的產業需求。 It can be seen from the foregoing embodiments and examples that the screw fastening device and the application method thereof according to the present invention can integrate the two purposes of loosening and increasing the torque and tightening without adding torque. By the structure of the invention, an instantaneous unwinding torque can be generated during the rotation to make the rotating member to be smoothly rotated and released, and it is no longer troubled by the long-term fastening of the screw, the nut or the screw to rust or deform. At the same time, it does not cause excessive tightening on the rotating member. In addition, the invention has a simple structure, does not occupy space, and can be disassembled according to requirements. Therefore, the embodiment of the present invention can not only generate an instantaneous unwinding torque, but also achieve the industrial demand for miniaturization, weight reduction, and increase of the matching change.
雖然本發明已以實施方式揭露如上，然其並非用以限定本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
