Abstract
【解決手段】本発明の低トルクタッピンネジは、軸に螺旋状に設けられた各ネジ山が三つの非対称の切削面で構成され、且つそのうちの任意の二つの隣り合う切削面間に切削エッジが設けられ、各該切削面に複数の鋸歯が開設されている。ゆえに、これら切削面が非対称で且つ複数の鋸歯を具備する設計により、これらネジ山でネジ立てと締結を行う時、物品との間に発生する摩擦を減らし、切削効率をアップするほか、大量の切り屑が溜まる現象を形成せず、締めつけトルクを減らして締結速度をアップし、物品に亀裂が発生するのを防止する。
【選択図】図3
Description
1.ネジ締め過程中に、該物品2の切り屑が有効に完全に切断されず、該物品2の繊維が該軸11に絡まり、このためこれらネジ山13がいずれも該物品2と緊密な接触状態を呈し、切削速度が遅くなるほか、該ネジ1の切削抵抗を増し、締めつけ過程で比較的大きなトルクが必要となり、使用の不便を増す。
2.前述したことを受け、該ネジ1の締結後に、一旦外在因子(たとえば地震)の振動の影響を受けると、該ネジ1の自動後退を極めて形成しやすく、このため、これらのネジ山13を該物品2に緊密に締めるだけでは十分な締結力が得られず、改善が待たれている。
3.さらに、これらネジ山13は円形に該軸11に環状に設けられ、このため切削時に発生する切り屑は、容易にこれらネジ山13間に溜まり、相互押圧と外向きの圧迫を発生し、このために切削速度が遅くなり、物品2が過大なトルクに耐えきれず亀裂を発生しやすくなり、ゆえにスピーディーな切削が達成できないのみならず、該ネジ1の締結に影響が生じる。
