Description
本發明是有關於一種循序性擊發扳機裝置，特別是指一種氣動工具的循序性擊發扳機裝置。 The present invention relates to a sequential firing trigger device, and more particularly to a sequential firing trigger device for a pneumatic tool.
參閱圖1與圖2，一種現有的氣動工具1主要包含一個機殼11、設置在該機殼11且用來控制氣流完成擊釘動作的一個閥桿12、受迫於一個壓力沿著該機殼11位移的一個保險件13、該機殼11樞接且能夠相對該閥桿12旋擺的一個扳機14，及與該扳機14樞接的一個操作件15。 Referring to FIG. 1 and FIG. 2, a conventional pneumatic tool 1 mainly comprises a casing 11, a valve stem 12 disposed on the casing 11 and used to control the airflow to complete the nailing action, and is forced to a pressure along the machine. A safety member 13 of the housing 11 is displaced, a trigger 14 pivotally coupled to the valve housing 12, and an operating member 15 pivotally coupled to the trigger 14.
當該保險件13受到一個壓力沿著該機殼11位移，且迫抵該操作件15一端部穩定於一個固定位置後，只需按壓該扳機14相對該閥桿12旋擺，就可以帶動該操作件15另一端部迫壓該閥桿12控制氣流完成擊釘動作。同時，該機殼11會因為擊釘時產生的反作用力而彈跳，使該操作件15在該保險件13彈跳瞬間往復位移的過程中，與該保險件13形成錯位關係，藉此，在該操作件15可自由旋動的情形下，即使按壓該扳機14也不會進行再次的擊發動 作。 When the safety member 13 is displaced along the casing 11 by a pressure, and the one end portion of the operating member 15 is stabilized at a fixed position, the trigger 14 can be rotated only by pressing the trigger 14 with respect to the valve stem 12. The other end of the operating member 15 urges the valve stem 12 to control the air flow to complete the nailing action. At the same time, the casing 11 bounces due to the reaction force generated during the nailing, so that the operating member 15 forms a misalignment relationship with the safety member 13 during the reciprocating displacement of the safety member 13 during the bounce. In the case where the operating member 15 is freely rotatable, even if the trigger 14 is pressed, no further firing is performed. Work.
惟，當前述反作用力較小而導玫彈跳幅度較小時，該操作件15很有可能無法脫離與該保險件13，而維持與該保險件13的迫抵關係，此時，若使用者釋放該扳機14，該閥桿12就會完成一次氣體循環，因此，當使用者不慎觸壓該扳機14，就會在沒有預期的狀況下，再次進行擊釘動作，不但容易釘壞工件，且會形成安全上的疑慮。 However, when the reaction force is small and the spring bounce is small, the operating member 15 may not be able to disengage from the safety member 13 and maintain the forced relationship with the safety member 13. At this time, if the user When the trigger 14 is released, the valve stem 12 completes a gas circulation. Therefore, when the user accidentally touches the trigger 14, the nailing operation is performed again under the unintended condition, and the workpiece is not easily nailed. And will form a security concern.
一種可連續序擊發的氣動工具，如美國專利第7322426號案(或如美國專利第7143918號案)，與本發明及前述先前技術之循序性擊發(單擊發)不同，參閱第7322426號案的圖3~圖8(以下加註前述專利案申請當時的標號)，主要是在一個觸發件32內側樞設有可以透過彈簧72提供一個偏壓力而相對一個操作件50位移的一個模式選擇件48與一個致動件46。藉此，以該操作件50、該觸發件32***作的先後順序，就可以如圖8、圖9所示，自動進入連續擊發狀態，或在圖4~圖7的單擊發狀態時，以該致動件46卡抵該操作件50(如圖7)，限制在一次擊發動作後，該操作件50復歸原位置前，該觸發件32都不能夠再相對一個致動器28旋擺。 A pneumatic tool capable of sequential firing, such as in U.S. Patent No. 7,322,426 (or U.S. Patent No. 7,433,918), which is different from the present invention and the prior art sequential firing (clicking), see No. 7322426 FIG. 3 to FIG. 8 (hereinafter referred to as the label of the aforementioned patent application) are mainly provided with a mode selection member which is disposed inside a trigger member 32 and is capable of providing a biasing force through the spring 72 and displacement relative to the operating member 50. 48 and an actuating member 46. Thereby, in the order in which the operating member 50 and the triggering member 32 are operated, as shown in FIG. 8 and FIG. 9 , the continuous firing state can be automatically entered, or in the click-on state of FIGS. 4 to 7 . When the actuating member 46 is engaged with the operating member 50 (as shown in FIG. 7), the trigger member 32 can no longer be pivoted relative to the actuator 28 before the operating member 50 is returned to the original position after one firing operation. .
惟，第7322426號案為了配合連續擊發/單擊發等模式，該操作件50需額外加工一個凹部51，該模式選擇件48需額外加工一個開口70，且該致動件46需額外加工一個凸部54，不但構 造設計上相當複雜，也提升加工的困難度，且重要的是，該模式選擇件48與該致動件46可移動的設計，會有磨損的問題。 However, in the case of the No. 7322426 case, in order to cooperate with the continuous firing/clicking mode, the operating member 50 requires an additional processing of a recess 51, the mode selecting member 48 requires an additional processing of an opening 70, and the actuating member 46 requires an additional processing. Convex 54, not only The design is quite complicated, and the difficulty of processing is also improved. What is important is that the design of the mode selection member 48 and the movable member 46 can be worn.
因此，本發明之目的，即在提供一種能夠提升操控性與使用安全性的氣動工具的循序性擊發扳機裝置。 Accordingly, it is an object of the present invention to provide a sequential firing trigger device that can improve the handling and safety of a pneumatic tool.
於是，該氣動工具包含一個機殼、可移動地設置在該機殼且用於控制氣流完成擊釘動作的一個閥桿，及可移動地設置於該機殼的一個保險件，該保險件可***作由遠離該閥桿的一個保險位置位移至鄰近該閥桿的一個解除保險位置，該循序性擊發扳機裝置包含：一個扳機、一個操作件，及一個頂抵件。 Thus, the pneumatic tool comprises a casing, a valve stem movably disposed in the casing and configured to control the airflow to complete the nailing action, and a safety member movably disposed on the casing, the safety component The operation is displaced from a secured position away from the valve stem to a disarmed position adjacent the valve stem, the sequential firing trigger device comprising: a trigger, an operating member, and an abutment member.
該扳機與該機殼樞接，且能夠相對該機殼在一個非觸發位置與一個觸發位置間旋擺。 The trigger is pivotally coupled to the housing and is rotatable relative to the housing between a non-trigger position and a trigger position.
該操作件與該扳機樞接，並包括一個觸壓部。 The operating member is pivotally connected to the trigger and includes a contact portion.
該頂抵件與該扳機樞接，並在該保險件位於該保險位置且該扳機位於該非擊發位置時，是與該操作件位於該保險件往該解除保險位置的一個移動路徑上。 The abutting member is pivotally connected to the trigger, and when the safety member is in the secured position and the trigger is in the non-fired position, the operating member is located on a moving path of the safety member to the unsecured position.
其中，在該扳機位於該觸發位置，且接著該保險件由該保險位置位移至該解除保險位置時，該操作件、該頂抵件與該保險件錯位，使得該操作件無法壓迫該閥桿位移，而無法完成擊釘動 作。 Wherein, when the trigger is in the trigger position, and then the safety member is displaced from the safety position to the release position, the operating member, the abutting member and the safety member are misaligned, so that the operating member cannot press the valve stem Displacement, unable to complete the nailing Work.
在該保險件位於該解除保險位置，且接著該扳機由該非觸發位置往該觸發位置旋擺時，該操作件的觸壓部會被該扳機帶動而壓迫該閥桿位移，以完成擊釘動作，且該頂抵件會在該扳機欲脫離該觸發位置時，頂抵該保險件，使得該扳機無法朝該觸發位置旋擺。 When the safety member is in the disengaged position, and then the trigger is swung from the non-trigger position to the trigger position, the touch portion of the operating member is driven by the trigger to press the valve stem to displace the nail to complete the nailing action. And the abutting member abuts the safety member when the trigger is to be disengaged from the trigger position, so that the trigger cannot swing toward the trigger position.
本發明之功效在於：利用該頂抵件與該操作件的位置變化，達到循序性擊發的目的，確保在一次擊釘動作後且該保險件釋放該操作件前，該扳機都不能夠再相對該閥桿擺動，而不會有誤觸該扳機再次進行擊釘動作的情形，進而提升操控性與使用安全性。 The effect of the invention is that the positional change of the abutting member and the operating member is used to achieve the purpose of sequential firing, and the trigger can not be opposite after a nailing action and before the safety member releases the operating member. The valve stem swings without accidentally touching the trigger to perform the nailing action again, thereby improving handling and safety.

It can be used to pivot against a top abutment 52 of the safety member 23 for centering. The abutting portion 52 has an adjacent abutting surface 521 and a blocking surface 522.
該樞軸6穿樞該扳機3、該操作件4的軸樞部41，及該頂抵件5的樞軸部51。 The pivot shaft 6 pivots the trigger 3, the pivot portion 41 of the operating member 4, and the pivot portion 51 of the abutting member 5.
該第一彈性元件7在本實施例中為一扭力彈簧，且設置在該扳機3與該機殼21間，並產生恆使該扳機3朝朝該非觸發位置旋擺的一個偏壓力。較佳的，該第一彈性元件7與該扳機3的第一樞部31同軸設置。 The first elastic member 7 is a torsion spring in the present embodiment and is disposed between the trigger 3 and the casing 21 and generates a biasing force that constantly causes the trigger 3 to swing toward the non-trigger position. Preferably, the first elastic member 7 is disposed coaxially with the first pivot portion 31 of the trigger 3.
該第二彈性元件8在本實施例中為一彈片，且設置在該扳機3與該操作件4間，並產生恆使該操作件4的觸壓部43朝遠離該閥桿22方向旋擺的一個偏壓力。 The second elastic member 8 is a spring piece in the embodiment, and is disposed between the trigger 3 and the operating member 4, and is configured to constantly rotate the contact portion 43 of the operating member 4 away from the valve stem 22.

較佳的，該第二彈性元件8與該第三彈性元件9與該扳機3的第二樞部32同軸設置。 Preferably, the second elastic member 8 and the third elastic member 9 are coaxially disposed with the second pivot portion 32 of the trigger 3.
本發明的循序性擊發扳機裝置在常態時，如圖3所示，該保險件23位於該保險位置而遠離該閥桿22，且該扳機3位於該非觸發位置時，該操作件4的觸壓部43與該頂抵件5的頂抵部52同樣遠離該閥桿22。此時，該操作件4的迫抵部42與該頂抵件5之頂抵部52的抵靠面521位於該保險件23往該解除保險位置的一個移動路徑上，而鄰近該保險件22的側面231。 When the sequential firing trigger device of the present invention is in a normal state, as shown in FIG. 3, the safety member 23 is located at the securing position away from the valve stem 22, and the trigger 3 is in the non-trigger position, the operating member 4 is pressed. The portion 43 is also remote from the valve stem 22 from the abutment portion 52 of the abutment member 5. At this time, the abutting portion 521 of the abutting portion 42 of the operating member 4 and the abutting portion 52 of the abutting member 5 is located on a moving path of the securing member 23 to the unsecured position, adjacent to the securing member 22 Side 231.
參閱圖3、圖6，當使用者先觸壓該扳機3由該非觸發位置依圖6中箭頭A所示的方向旋擺至該觸發位置，且接著該保險件23受迫於一工件(圖未示)由該保險位置依圖中箭頭B所示的方向位移至該解除保險位置時，因為該扳機3在先移動至該觸發位置之後，亦會同時連動該操作件4的迫抵部42、該頂抵件5的頂抵部52偏離該保險件23的移動路徑，因此在該保險件23移動至該解除保 險位置後，該操作件4的迫抵部42與該頂抵件5之頂抵部52的抵靠面521與該保險件23錯位。此時，由於該操作件4的迫抵部42與該觸發部43能夠以該軸樞部41為中心旋擺，因此，在該觸發部43接觸該閥桿22時，會被該閥桿22推頂，而朝遠離該閥桿22的方向擺動，並不會迫壓該閥桿22位移，所以無法進行擊釘動作。 Referring to FIG. 3 and FIG. 6, when the user first touches the trigger 3, the non-trigger position is swung to the trigger position in the direction indicated by the arrow A in FIG. 6, and then the safety member 23 is forced to a workpiece (Fig. When the safety position is displaced to the release position according to the direction indicated by the arrow B in the figure, since the trigger 3 is moved to the trigger position, the abutting portion 42 of the operating member 4 is also linked at the same time. The top abutting portion 52 of the abutting member 5 is offset from the moving path of the securing member 23, so that the safety member 23 is moved to the release After the dangerous position, the abutting portion 42 of the operating member 4 and the abutting surface 521 of the abutting portion 52 of the abutting member 5 are misaligned with the securing member 23. At this time, since the abutting portion 42 of the operating member 4 and the trigger portion 43 can be swung around the pivot portion 41, when the trigger portion 43 contacts the valve stem 22, the valve stem 22 is used. When the ejector is pushed and moved away from the valve stem 22, the valve stem 22 is not forced to be displaced, so that the nailing operation cannot be performed.
參閱圖7、圖8，當該保險件23先受迫於該工件而依圖7中箭頭A所示的方向位移至該解除保險位置，且接著該扳機3依圖8中箭頭B所示的方向由該非觸發位置旋擺至該觸發位置時，由於在該保險件23往該解除保險位置移動時，該操作件4的迫抵部42與該頂抵件5之頂抵部52的抵靠面521會被該保險件23的側面231推頂而旋擺，並靠近該閥桿22，因此接著在該扳機3往該擊發位置移動的過程中，該操作件4的觸壓部43會隨該扳機3擺動而依圖8中箭頭C所示的方向壓迫該閥桿22(往相反於該箭頭B的方向位移)，以完成擊釘動作。同時，該頂抵件5之頂抵部52的抵靠面521，會因為該扳機3的位置變化，且由於該軸樞部51至該頂抵部52的長度短於該操作件4之軸樞部41至該迫抵部42的長度，而脫離該保險件23的側面231，此時，該頂抵件5是以相反於該操作件4的旋擺方向以相反於該操作件4的旋擺方向，旋擺至脫離該保險件23，而與該保險件23錯位(如圖8)。 Referring to FIG. 7 and FIG. 8, when the safety member 23 is first forced to the workpiece, it is displaced to the release position in the direction indicated by the arrow A in FIG. 7, and then the trigger 3 is shown by the arrow B in FIG. When the direction is swung from the non-trigger position to the trigger position, the abutting portion 42 of the operating member 4 abuts against the abutting portion 52 of the abutting member 5 when the securing member 23 moves to the releasing position. The face 521 is pushed up by the side 231 of the securing member 23 and is swung up and close to the valve stem 22, so that the touch portion 43 of the operating member 4 will follow during the movement of the trigger 3 to the firing position. The trigger 3 is swung to press the valve stem 22 in the direction indicated by the arrow C in Fig. 8 (displaced in the opposite direction to the arrow B) to complete the nailing action. At the same time, the abutment surface 521 of the abutting portion 52 of the abutting member 5 may change due to the position of the trigger 3, and the length of the pivot portion 51 to the abutting portion 52 is shorter than the axis of the operating member 4. The length of the arm portion 41 to the urging portion 42 is separated from the side surface 231 of the securing member 23, and at this time, the abutting member 5 is opposite to the swinging direction of the operating member 4 to be opposite to the operating member 4. In the direction of the swing, it is swung out of the safety member 23 and is displaced from the safety member 23 (Fig. 8).
參閱圖9，此時，該頂抵件5之頂抵部52的卡阻面522 會相對應於該保險件23的側面232，且隨著該扳機3欲脫離該觸發位置，而抵靠該保險件23的側面232，使得該扳機3維持在該觸發位置。藉此，若要進行下次的擊釘動作，必須要反向於工件方向提起該氣動工具2，先釋放該保險件23復位至保險件位置，才能夠釋放該扳機3復位至該非觸發位置，而再次循序進行擊釘動作。 Referring to FIG. 9, at this time, the blocking surface 522 of the abutting portion 52 of the abutting member 5 is 522. Corresponding to the side 232 of the securing member 23, and as the trigger 3 is intended to disengage from the triggering position, against the side 232 of the securing member 23, the trigger 3 is maintained in the triggered position. Therefore, if the next nailing operation is to be performed, the pneumatic tool 2 must be lifted in the direction opposite to the workpiece, and the safety member 23 is released to be reset to the position of the safety member before the trigger 3 can be released to the non-trigger position. And the nailing action is performed sequentially.
經由以上的說明，可將前述實施例的優點歸納如下： Through the above description, the advantages of the foregoing embodiments can be summarized as follows:
1、本發明能夠利用該頂抵件5與該操作件4的位置變化，限制使用者一定要依循先迫壓該保險件23、再按壓該扳機3、釋放該保險件23、釋放該扳機3的順序，才能完成一個擊釘程序，及進行下一次的擊釘動作。藉此，達到循序性擊發的目的，確保在一次擊釘動作後且該保險件23釋放該操作件4前，該扳機3都不能夠再相對該閥桿22擺動，而不會有誤觸該扳機3再次進行擊釘動作的情形，進而提升操控性與使用安全性。 1. The present invention can utilize the positional change of the abutting member 5 and the operating member 4, restricting the user from having to press the safety member 23 first, then pressing the trigger 3, releasing the safety member 23, and releasing the trigger 3 In order to complete a nailing procedure and the next nailing action. Thereby, the purpose of the sequential firing is achieved, and it is ensured that the trigger 3 can no longer swing relative to the valve stem 22 after a nailing operation and before the safety member 23 releases the operating member 4, without accidentally touching the valve. The trigger 3 performs the nailing operation again, thereby improving the handling and safety of use.
2、且本發明的操作件4、頂抵件5皆為板片式設計，不但構造簡單、加工容易，且同軸在固定位置旋擺的方式，能夠降低磨損的程度，延長使用壽命。 2. The operating member 4 and the abutting member 5 of the present invention are all of a plate type design, which is not only simple in structure, easy to process, but also coaxially rotated at a fixed position, which can reduce the degree of wear and prolong the service life.
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
