Description

木螺絲
　　本創作有關於一種螺絲，尤指一種應用於鎖固木材之木螺絲。
　　按，螺絲具有快速鎖接固定的優點，因此已廣泛被應用於結合各種材料的工件上，例如木材、塑膠、金屬或水泥等，一般木螺絲作工時是將螺絲尖端鑽入表面，並利用螺牙切削工件以形成螺紋孔，再進一步螺入工件的內部，達到螺固的目的。
　　然，螺絲在螺入工件時，會產生一旋轉扭力，當扭力過大便會導致螺絲產生滑牙或螺紋孔破裂等情形，而螺絲的設計影響著旋轉扭力的大小，影響扭力的因素非常多，像螺絲的直徑與螺距越大其扭力需要越大，相對的得花費更多的力氣和時間方能使螺絲與工件鎖固，但使用者卻常常忽略了螺絲的設計需求，而造成一些使用上的缺憾。
　　為避免上述之情形發生，本創作人潛心研究，並結合從事相關事業的多年經驗，提出一種木螺絲，以達到良好的螺固效果。
　　本創作之目的在於，提供一種木螺絲，其設計之尺寸規格係經由本創作人重複驗證後，成為可降低旋轉扭力及提升鎖固強度之螺絲。
　　本創作提供一種木螺絲，該木螺絲包含一螺頭及一桿體，該螺頭頂部設有供螺絲起子旋扭之旋動槽；該桿體為一圓形桿體並由該螺頭底端向下延伸，該桿體環設有螺牙部，該螺牙部設為等角螺牙，該等角螺牙之對稱角和為40度，其對稱角和的容許範圍可增加5度或減少5度，該螺牙部之牙尖至該桿體端面所形成的牙高為0.5~3.5公厘，該等角螺牙之外徑為6~14公厘，該外徑與該螺牙部之螺距比值為1~2.5。
　　綜上所述，本創作人係依據設計理論，並實際的使用測試，計算出螺絲最適當的尺寸規格，使螺絲作工時可有效降低旋轉扭力並增加鎖固強度，進而減少螺絲與工件產生崩壞之情形發生，俾利提高工作效率與使用效益。
　　以下藉由具體實施例配合所附的圖式詳加說明，當更容易瞭解本創作之目的、技術內容、特點及其所達成之功效。
　　首先，請參閱第1及2圖所示，為本創作之第一實施例，本創作一種木螺絲，該木螺絲1包含一螺頭2及一桿體3，其中:
　　該螺頭2頂部設有供螺絲起子旋扭之旋動槽21；該桿體3為一圓形桿體並由該螺頭2底端向下延伸，其末端形成尖錐部31，該桿體3環設有螺牙部32，該螺牙部32設為等角螺牙，等角螺牙是指該螺牙部32在牙尖321處的第一切削面322及第二切削面323與該牙尖321延伸之水平面形成二對稱角θ，該對稱角θ理想角度為20度，二對稱角θ和為40度，該對稱角θ和的容許範圍可增加5度或減少5度，該牙尖321至該桿體3端面所形成的牙高H為0.5~3.5公厘，該等角螺牙之外徑D為6~14公厘，該外徑D與該螺牙部32之螺距P比值為1~2.5，藉此規格設計，使木螺絲1可有效降低作工時之旋轉扭力，進而增加鎖固強度。
　　該比值之關係式：1≦外徑D／螺距P≦2.5。
　　請同時參閱第3及4圖所示，為本創作之第二實施例，本創作木螺絲1a之桿體3a底端一側更成型有一割尾槽33a，其供容納並排出切削工件所產生之切屑。
　　再參閱第5及6圖所示，為本創作之第三實施例，本創作木螺絲1b之桿體3b底部設置有一切削螺牙部34b，該切削螺牙部34b具有三個螺旋牙鋒341b，該螺旋牙鋒341b係由該尖錐部31b底端往上與該螺牙部32b之螺旋方向呈同向螺旋設置，該螺旋牙鋒341b之螺旋角度相較於該螺牙部32b之螺旋角度為陡，使木螺絲1b可於螺入工件時，提升對工件物料的斬削效果；且該螺牙部32b自該尖錐部31b起取適當長度於外周緣設有鋸齒切刃324b，得以有效降低木螺絲1b旋動時的摩擦力；請同時參閱第7及8圖，為本創作之第四實施例，本實施例係與第二實施例作結合，該木螺絲1c更可同時增設該割尾槽33c，以達到極佳的工作效率與使用效益。
　　再參閱第9及10圖所示，為本創作之第五實施例，本創作木螺絲1d之桿體3d之末端可設成一鑽頭部31d，而該螺牙部32d自該鑽頭部31d起取適當長度於外周緣設有鋸齒切刃324d。
　　再參閱第11及12圖所示，為本創作之第六實施例，本創作木螺絲1e之桿體3e之末端可設成一釘頭部31e，而該螺牙部32e自該釘頭部31e起取適當長度於外周緣設有鋸齒切刃324e。
　　綜上所述，僅為本創作之較佳實施例而已，在不離本創作精神之範圍，熟習此項技藝者憑之而作之各種變化、修飾與應用，皆應涵蓋於本創作中，因此本創作的保護範圍當視後附的申請專利範圍所界定者為準。
