Description
本發明係有關於釘槍結構，尤指一種裝設有循序式扳機結構的釘槍。The present invention relates to a nail gun structure, and more particularly to a nail gun equipped with a sequential trigger structure.
按，為了改善早期釘槍扣壓扳機便可擊發釘子所導致的使用安全性低落之問題，目前已有業者發展出一種具循序式擊發扳機結構的釘槍，藉以提高釘槍的使用安全性。In order to improve the safety of the use of nails caused by the early nail gun crimping trigger, the manufacturer has developed a nail gun with a sequential firing trigger structure to improve the safety of the nail gun.
如中華民國公告第M250776號之『打釘槍之全循序單擊發裝置』新型專利，其係釘槍的扳機內部彈性樞設有一壓制片，該壓制片可隨扳機連動，並適時受保險臂一端作動樞轉，用以推抵氣閥開關進行擊發動作，其中，壓制片上與氣閥開關相對接觸推抵之處，形成有一預定高度的突起部位，該突起部位是由壓制片一體沖壓突設而成，以令釘槍擊發後，而撞針活塞停留在行程中途，使補風口被其阻擋封閉，同時保險臂一端亦已離開壓制片，使壓制片往前樞轉復位時，仍能藉由該壓制片預定高度之突起部位與氣閥開關保持於基本壓抵狀態，讓高壓氣體仍能持續進入缸體中推動撞針活塞，以排除補風口被阻擋封閉之情形，而能順利完成全部擊釘程序。For example, in the Republic of China Announcement No. M250776, the new patent for the "single-clicking and firing device for nailing guns" is provided with a pressing piece for the internal elastic of the trigger of the nail gun, which can be linked with the trigger and timely secured by the trigger arm. One end is pivoted to push the gas valve switch to perform a firing operation, wherein the pressing piece is pressed against the gas valve switch to form a protruding portion of a predetermined height, and the protruding portion is integrally stamped by the pressing piece. In order to make the nail gun fire, the striker piston stays in the middle of the stroke, so that the air inlet is blocked by the air, and the end of the safety arm has also left the pressing piece, so that the pressing piece can still be pivoted forward and still can be used by The protruding portion of the pressing piece is kept at a predetermined pressure and the gas valve switch in a substantially pressed state, so that the high pressure gas can continue to enter the cylinder body to push the striker piston, so as to eliminate the situation that the air filling port is blocked and closed, and all the nailing can be successfully completed. program.
值得注意的是，在前述專利釘槍結構的扣壓擊發過程中，該壓制片的突起部位必須能精准地和氣閥開關接觸推抵才能完成釘子的擊發，因而提高壓制片一體沖壓形成突起部位的加工精準度，有製造費時且製作成本提高之問題，此外，由於突起部位是由片狀的壓制片沖壓形成，本身結構強度低而容易在扣壓擊發過程中因衝擊動作造成壓制片結構被破壞，在實際應用時，容易有突起部位與氣閥開關接觸推抵精準度不佳之問題。It is worth noting that in the process of the crimping and firing of the patented nail gun structure, the protruding portion of the pressing sheet must be accurately contacted with the gas valve switch to complete the firing of the nail, thereby improving the processing of forming the protruding portion by pressing the stamping piece integrally. Accuracy, there is a problem that manufacturing is time consuming and the manufacturing cost is increased. In addition, since the protruding portion is formed by stamping a sheet-shaped pressed sheet, the structural strength of the sheet itself is low, and the pressed sheet structure is easily broken due to the impact action during the crimping and firing process. In practical applications, it is easy to have a problem that the protruding portion is in contact with the gas valve switch to push the precision.
為改善習知釘槍的循序性扳機擊發結構之問題，另有中華民國公告號第M334002號提供一種『釘槍循序板機』新型專利，其係指釘槍之保險板機擊發機構，該保險板機擊發機構係設有一保險件、一板機裝置、一循序裝置及一擊發裝置，該保險件係設於板機裝置，且板機裝置另端係設有擊發裝置，循序裝置設於板機裝置及擊發裝置之間，該保險件係抵壓於加工物件後通過循序裝置之彈跳件抵壓擊發裝置完成擊發。值得注意的是，該專利前案的板機需設有一樞接部及滑動部供循序裝置設置，且循序裝置是由一樞軸件、一彈復件、一撥動件、一滑動件、一彈性件、一頂持件及該彈跳件組成者，其連動結構明顯有結構複雜而容易有擊發不順，且增加組裝製造成本之問題。In order to improve the problem of the sequential trigger firing structure of the conventional nail gun, the Republic of China Announcement No. M334002 provides a new patent for the "nail gun sequential board machine", which refers to the insurance board machine firing mechanism of the nail gun. The trigger mechanism of the trigger machine is provided with a safety component, a trigger device, a sequential device and a firing device. The safety device is disposed on the trigger device, and the trigger device is disposed at the other end of the trigger device, and the sequential device is disposed on the plate. Between the machine device and the firing device, the safety member is pressed against the workpiece, and the firing device is pressed against the firing device to complete the firing. It is worth noting that the plate machine of the prior patent requires a pivoting portion and a sliding portion for the sequential device, and the sequential device is composed of a pivoting member, a resilient member, a dialing member and a sliding member. An elastic member, a top holding member and the member of the bouncing member have a complicated structure and are easy to have a bad firing, and increase the assembly and manufacturing cost.

The recess 20 of the member 20 is substantially perpendicular to the traction member 30 to form a safety release state of the nail gun A to be fired.
第6圖係第5圖釘槍A扣壓扳機件20擊發瞬間的結構。通過第5圖的扣壓空間R2以及相抵的牽引件30與擊發開關A3壓柱A32，釘槍A經扣壓扳機件20後，以牽引件30壓制擊發開關A3完成擊發釘設動作。該保險件10於擊發時退離釘設面S而受壓縮彈簧13牽引彈性復位前伸，形成與牽引件30分離之瞬間狀態，由於保險件10前伸使樞轉空間R1擴大，該牽引件30在完成擊發後，將受凹槽21內壓縮彈簧23頂推凸伸出凹槽21，回復如第4圖之保險鎖住狀態。Fig. 6 is a structure in which the nail of the fifth figure nail gun A is pressed at the moment of firing. Through the pressing space R2 of FIG. 5 and the abutting traction member 30 and the firing switch A3 pressing the column A32, after the nail gun A presses the trigger member 20, the firing member 30 is pressed by the pulling member 30 to complete the firing and nailing operation. The safety member 10 is retracted from the nailing surface S at the time of firing and is elastically retracted by the compression spring 13 to form a state of separation from the traction member 30. Since the safety member 10 is extended to extend the pivoting space R1, the traction member is extended. After the completion of the firing, the compression spring 23 in the groove 21 is pushed up and projected out of the groove 21 to return to the safety lock state as shown in FIG.
綜上所述，本發明透過上述釘槍之循序式扳機結構，利用設 有斜面31及滑槽32的牽引件30與保險件10、扳機件20及壓縮彈簧的配合即可完成釘槍A的循序式扳機操作，相較於習知循序式扳機結構，確實具有構件精簡而降低組裝生產成品之功效，且由於本發明以壓縮彈簧套置在構件外部提供彈性復位功能，具有較佳的結構強度且可避免彈性元件形變影響擊發順暢度之問題。值得說明的是，由於本發明釘槍A在保險鎖住狀態時，扳機件20係與擊發開關A3錯位，同時也通過牽引件30連動使扳機件20抵壓於握柄A2上而不具有扣壓空間R2，而得以確保釘槍A在保險鎖住狀態下無法擊發，具明顯提升使用安全性之功效。In summary, the present invention utilizes the sequential trigger structure of the nail gun described above. The traction member 30 having the inclined surface 31 and the sliding groove 32 cooperates with the safety member 10, the trigger member 20 and the compression spring to complete the sequential trigger operation of the nail gun A. Compared with the conventional sequential trigger structure, the component has a simplified structure. The utility model has the advantages of reducing the assembly and production of the finished product, and the invention provides the elastic reset function by the compression spring sleeve on the outside of the component, has better structural strength and can avoid the problem that the deformation of the elastic component affects the smoothness of the firing. It should be noted that, because the nail gun A of the present invention is in the lock state, the trigger member 20 is misaligned with the firing switch A3, and the trigger member 30 is also interlocked by the pulling member 30 to press the trigger member 20 against the handle A2 without being buckled. The space R2 ensures that the nail gun A cannot be fired under the safety lock state, and the utility model has the effect of obviously improving the safety of use.
