Description

本考案は釘打ちガンの構造に関するもので、更に詳しく言えば、釘が切れた状態に於いて撃発を防ぐことができる安全装置のある釘ガン構造を指したものである。   The present invention relates to the structure of a nail gun, and more particularly, to a nail gun structure having a safety device capable of preventing a fire when a nail is cut.

常用されている釘打ちガンはその釘打ちガン本体内の釘打ち装置の前端に射出部が設けられ、その射出部の下側に釘箱が連通して設けられ、その釘箱は釘の容納に供される。更にその釘打ち本体の握り柄部に引き金が設けられてあり、その引き金は釘打ちガン内の高圧空気の流れを制御することができ、それによって釘打ちガンの撃針の撃発を制御し、撃針の撃発力によって射出部内の釘を押し出して工作物内に打ち込む。   A commonly used nailing gun is provided with an ejection section at the front end of a nailing device in the nailing gun body, and a nail box is provided below the ejection section so as to communicate with the nail box. To be served. Further, a trigger is provided on the handle of the nailing body, and the trigger can control the flow of high pressure air in the nailing gun, thereby controlling the firing of the firing pin of the nailing gun, The nail in the injection part is pushed out and driven into the workpiece by the firing force of.

ところが、一般使用者が従来の釘打ちガンを使用して仕事をする場合、その多くは連続撃発であるが、使用者は現在釘箱内にある釘の数を知ることができない。そのために釘箱内の釘が使い切れた場合、使用者は釘切れの状態に於いて依然引き金を撃発し、甚だしくは数回撃発して箱内には確かに釘がないことを確かめ、それから新たに箱内に釘を装填する。ところが釘打ちガン自身の構造から言えば、撃針およびその他撃発装置が釘切れ状態で撃発された場合、それ自身の構造および使用寿命に対する影響は極めて大きく、甚だしくは損傷する可能もある。   However, when a general user works using a conventional nail gun, most of the operations are continuous attacks, but the user cannot know the number of nails currently in the nail box. Therefore, if the nails in the nail box are exhausted, the user still fires the nail in the broken condition, firing several times to make sure there are no nails in the box, and then Load nails in the box. However, in view of the structure of the nail gun itself, if the firing pin and other firing devices are fired in a nail-cut state, the structure and service life of the firing needle and the like are extremely large, and may be severely damaged.

本考案の目的は、釘打ちガンが釘切れ状態で撃発することを防止し、撃発装置および撃針等構造の空打ちにより損傷したり、または使用寿命が短縮したりすることを防ぐ釘打ちガンの空打ち防止構造を提供することである。   An object of the present invention is to prevent a nail gun from firing in the state of a broken nail, and to prevent the nail gun from being damaged by an empty shot of a firing device and a structure such as a firing pin or shortening the service life of the nail gun.

次に本実施例の作動原理について詳しく説明する。
図4に示すように、釘箱14内に釘がない場合、その回転棒20のばね当て片24はばね241の弾性押さえ力を受け、その制動片30を釘箱14内の方向へ押し込み、この場合、嵌め当て片231は引き金12の後側に当て付けている。これにより、釘箱14内に釘がない場合、嵌め当て片231は自動的に引き金12の後側に嵌め当たって回転棒20は安全モードにあり、使用者は引き金12を引くことができなく、釘打ちガンが釘切れ状態に於いての撃発を確実に防止することができ、かつ撃発装置および撃針等構造が空打ちしたために損傷したり、または使用寿命を短縮したりすることがないよう確保する。
Next, the operation principle of the present embodiment will be described in detail.
As shown in FIG. 4, when there is no nail in the nail box 14, the spring contact piece 24 of the rotating rod 20 receives the elastic pressing force of the spring 241, and pushes the braking piece 30 in the direction inside the nail box 14. In this case, the fitting piece 231 is applied to the rear side of the trigger 12. Thereby, when there is no nail in the nail box 14, the fitting piece 231 automatically fits on the rear side of the trigger 12, the rotating rod 20 is in the safety mode, and the user cannot pull the trigger 12. The nailing gun can reliably prevent firing when the nail is broken, and also prevent the firing device and the structure of the firing pin and the like from being hit without being damaged or shortening the service life. Secure.

釘箱14内に釘が装填されると、釘箱内の釘押し機構15は中に貯蔵されてある釘を持続的に射出部13内に送り込み、釘が釘箱14の頂端に押し込まれると図5に示すように釘は自動的に嵌めほぞ31を釘箱14から押し出し、かつ回転棒20を回すように動かし、その嵌め当て片231も自動的に引き金12の後側から脱出し、回転棒20は自動的に自由撃発モードに切り替え、使用者は自由に引き金を引くことができ、釘箱14内の釘を打ち出すことができる。   When the nail is loaded in the nail box 14, the nail pushing mechanism 15 in the nail box continuously feeds the nail stored therein into the injection unit 13, and when the nail is pushed into the top end of the nail box 14. As shown in FIG. 5, the nail automatically pushes the fitting tenon 31 out of the nail box 14 and moves the rotating rod 20 to rotate, and the fitting piece 231 also automatically escapes from the rear side of the trigger 12 and rotates. The bar 20 automatically switches to the free-fire mode, and the user can freely trigger and strike the nail in the nail box 14.

また、押しアーム25および押しボタン251の設置により、釘箱内の最後の釘が射出部13内に進入すると釘箱14内にはその嵌めほぞを押し動かす釘がないので、回転棒20はばね241の弾性押し付け力を受けて元の位置に復帰し、かつ嵌め当て片231を引き金12の後側に当て付けて安全モードに復帰し、そのために最後の釘は撃発不能になる。この場合、使用者は手動で回転棒20の押しボタン251を押して嵌め当て片231を脱出させ、手動に回転棒20を自由撃発モードに切り替え、引き金を引いて撃発する。また釘箱14内の釘が引っかかりまたは他の状況が発生した場合、使用者はその押しボタン251を利用して引き金を引くことができ、故障状態を排除することができる。   When the last nail in the nail box enters the injection section 13 due to the installation of the push arm 25 and the push button 251, there is no nail in the nail box 14 for pushing the mortise in the nail box 14. Under the elastic pressing force of 241, it returns to the original position, and the fitting piece 231 is applied to the rear side of the trigger 12 to return to the safety mode, so that the last nail cannot be fired. In this case, the user manually pushes the push button 251 of the rotating rod 20 to cause the fitting piece 231 to escape, manually switches the rotating rod 20 to the free firing mode, and triggers and fires. In addition, when a nail in the nail box 14 is caught or another situation occurs, the user can use the push button 251 to trigger and eliminate a failure state.

本実施例は回転棒20と制動片30との組み合わせを利用し、釘箱14内に釘がない場合、その回転棒20の嵌め当て片231は引き金12の後側に嵌め当てて引き金12の撃発を防止し、釘打ちガンが釘切れ状態での撃発を確実に防止することができ、撃発装置および撃針等構造が空打ちによって損害したり、または使用寿命が短縮したるすることがないよう確保する。かつその押しアーム25および押しボタン251の設置は手動で切り替えて引き金を引くことができ、それによって最後の釘を撃発しまたは故障状況を排除することができる。   This embodiment utilizes a combination of the rotating rod 20 and the braking piece 30, and when there is no nail in the nail box 14, the fitting piece 231 of the rotating rod 20 is fitted on the rear side of the trigger 12, and Prevents firing and ensures that nailing guns do not fire when nails are broken, so that structures such as the firing device and the firing pin are not damaged by idle driving or the service life is shortened. Secure. And the installation of its push arm 25 and push button 251 can be manually switched and triggered, thereby firing the last nail or eliminating a fault condition.
