參閱圖1、圖2,習知螺絲1包含有一螺頭11,一由該螺頭11向外延伸之桿體12,且該桿體12相反於螺頭11一端形成有一鑽鎖部13,以及複數環設於該桿體12上之螺牙14;其中,該每一螺牙14上具有三個切角141,以及該任二切角141連結間具有一銜接面142,而前述該切角141實際上製造後係呈一圓弧設計,亦即取該每一切角141為例,且該每一切角141係以該桿體12之中心a向外分別延伸有二條假想之邊界線a1,且該二邊界線a1間之夾角a2介於50度以上,此時該切角141之所形成的弧度,其至少係以該螺牙14半徑的三分之一以上,即如該螺牙14半徑為3公釐(mm),則該切角141之圓周為3/3=1R以上;故鎖合時,將該鑽鎖部13緊抵於物件(圖中未示)上,藉由鎖合工具(圖中未示出)連動該螺頭11,進而帶動該等螺牙14之切角141切削該物件,以達該螺絲1旋鎖進入該物件中。1 and 2, the
惟,實際使用後發現,習知該螺絲1在鎖合過程中,鑒於該切角141係呈弧度型態設計,俾使連接於該任二切角141間之銜接面142亦同樣呈圓弧之設置,易導致該等切角141鑽鎖過程無法有效進行切削,同時亦使該銜接面142於切削過程中與該物件產生相互摩擦,且該等切角141與銜接面142間更無多餘空間可供切屑容置,除增加該螺絲1鎖合阻力導致切削速度變慢,易使該物件無法承受過大之扭力而產生裂材現象,故不但無法有效達到快速鎖合,進而影響該螺絲1之鎖合定位,仍有待改進。However, after actual use, it was found that during the locking process of the
因此,本發明之目的是在提供一種具快速鎖設之緊固件,其鎖合過程中具有降低鎖合阻力與扭力及增加鎖合速度等功效。Therefore, the object of the present invention is to provide a fast-locking fastener which has the functions of reducing the locking resistance and torsion force and increasing the locking speed during the locking process.
於是,本發明具快速鎖設之緊固件包含有一螺頭,一由該螺頭向外延伸之桿體,且該桿體相反該螺頭之一端形成有一鑽鎖部,以及複數螺旋環設於該桿體上之螺牙;其中,該緊固件係以一旋鎖方向以鑽鎖入一物件中,該桿體具有至少三個桿體面,以形成為非圓形型湃設置,同時該桿體具有一由該鑽鎖部延伸至該螺頭之中心處的縱軸;另,該每一螺牙具有至少三個牙面,任二相鄰牙面間形成有一弧接面,該每一弧接面之二端與位於該弧接面相鄰二側之該等牙面的相接處形成有兩個接點,且該每一弧接面之該二接點間形成有一弧切部,而前述該等螺牙在相同位置之弧切部依序由該螺頭往該鑽鎖部方向排列相互串聯形成有一第一軸線,且該第一軸線可相對該縱軸呈平行延伸設置,當然該第一軸線更可相對該縱軸呈繞旋的延伸設置,同時以該縱軸為基準並通過該弧切部延伸有一假想線,且以該縱軸為基準通過該二接點延伸有二邊界線,該每一邊界線與該假想線間形成有一介於20度至25度間之夾角,以便該二邊界線之間所形成之夾角不超過50度,使位於該二接點間之該弧切部所形成之弧度係以不超過該最大螺牙半徑之四分之一設置,有利於鎖合時,該緊固件得以呈銳利且快速方式進行切削,大大減少該等牙面鎖合過程中與鎖合之物件產生摩擦,以降低鎖合扭力,有效提昇該緊固件之切削能力與增加鎖合速度,使該螺牙具有多餘空間可供切屑容置,亦可免除切屑堆積而形成裂材之情事發生。Therefore, the fastener with quick locking of the present invention includes a screw head, a rod body extending outward from the screw head, and a drill lock portion is formed at one end of the screw head opposite to the rod body, and a plurality of spiral rings are arranged at The screw thread on the rod; wherein the fastener is drilled and locked into an object in a twist-locking direction, the rod has at least three rod faces to be formed as a non-circular type wa, and the rod The body has a longitudinal axis extending from the drill lock portion to the center of the screw head; in addition, each thread has at least three tooth surfaces, and an arc joint surface is formed between any two adjacent tooth surfaces. Two contact points are formed between the two ends of the arc joint surface and the tooth surfaces located on two adjacent sides of the arc joint surface, and an arc cut part is formed between the two joint points of each arc joint surface , And the arc cut parts of the aforementioned threads at the same position are arranged in series from the screw head toward the drill lock part to form a first axis, and the first axis can extend parallel to the longitudinal axis, Of course, the first axis can be extended in a spiral with respect to the longitudinal axis. At the same time, an imaginary line extends through the arc cut portion based on the longitudinal axis, and extends through the two joints based on the longitudinal axis. Two boundary lines, each boundary line and the imaginary line form an angle between 20 degrees and 25 degrees, so that the angle formed between the two boundary lines does not exceed 50 degrees, so that it is located between the two points of contact The arc formed by the arc cut part is set not to exceed one-fourth of the radius of the maximum thread, which is conducive to the cutting of the fastener in a sharp and fast manner during the locking, which greatly reduces the locking of the tooth surfaces During the process, friction is generated with the object to be locked to reduce the locking torque, effectively improve the cutting ability of the fastener and increase the locking speed, so that the thread has extra space for chip accommodation, and it can also avoid the accumulation of chips.

有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之較佳實施例的詳細說明中,將可清楚的明白。The foregoing and other technical content, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.
參閱圖3、圖4,本發明之一較佳實例,包含有一螺頭31,一由該螺頭31向外延伸之桿體32,一呈複數螺旋環設於該桿體32上之螺牙33,以及一相反於該螺頭31且形成於該桿體32另一端之鑽鎖部34;其中,該緊固件3係以旋鎖方向以鑽鎖入一物件(圖中未示)中,同時該桿體32具有一由該鑽鎖部34延伸至該螺頭31之中心處的縱軸α1。Referring to Figures 3 and 4, a preferred example of the present invention includes a
仍續前述,該螺牙33呈複數個設於該桿體32上,而該每一螺牙33具有至少三個牙面331,任二相鄰該牙面331間形成有一弧接面332,且該每一弧接面332之二端與位於該弧接面332相鄰二側之該等牙面331的相接處形成有兩個接點333,且該每一弧接面332之該二接點333間形成有一弧切部334,以該縱軸α1為中心點至該弧切部334之距離定義為一最大螺牙半徑r2,而前述該等螺牙34在相同位置之弧切部334依序由該螺頭31往該鑽鎖部34方向排列相互串聯形成有一第一軸線α2,同時以該縱軸α1為基準並通過該弧切部334延伸有一假想線B,且以該縱軸α1為基準通過該二接點333延伸有二邊界線B1,該每一邊界線B1與該假想線B間形成有一介於20度至25度間之第一夾角θ1 ,以便該二邊界線B1之間所形成之第二夾角θ2不超過50度的設計,使該位於該二接點333間之該弧切部334所形成的弧度,其係以不超過該最大螺牙半徑r2的四分之一,即如該最大螺牙半徑r2為3公釐(mm),則該弧切部334之圓周為3/4=0.75R以下,由前可知,當位於該二接點333間之該弧接面332上之該弧切部334所形成之弧度值會影響旋時之切削圓弧的角度,其弧度越大即切削圓弧的角度也越大,反觀,當該弧切部所形成之弧度越小即切削圓弧的角度也越小,故該弧接面332整體為呈一尖銳角型態之設置,同時該第一軸線α2相對該縱軸α1呈平行延伸設置,即如圖3所示,當然亦可如圖6所示,該第一軸線α2相對該縱軸α1呈繞旋延伸的設置,以下說明仍以圖3及圖4所示為例。As mentioned above, the
再者,該桿體32具有至少三個桿體面321,以形成為非圓型態設置,特別的是,在本實施例中該桿體32為多角型態設置,即為呈三角形型態的設置,同時該桿體32還具有至少三個端角面322,且該每一端角面322係延伸於任二相鄰之該桿體面321之間,而該等桿體面321、端角面322之形狀分別與該等牙面331、弧接面332之型狀符合,以便該桿體32之整體外型對應於該螺牙33之外型,同時該端角面322具有一端角點323,該桿體32以該縱軸α1為中心點至該端角點323之距離為一最大桿體半徑r1,同時位於該每一端角面322之該端角點323所形成之弧度,其係以不超過該最大桿體半徑r1的四分之一,當然形成於該桿體32另一端之該鑽鎖部34亦同樣形成三角形態樣的尖尾設置,即如圖5之端視圖所示,另,該每一螺牙33之牙面331可為三個設置,即為與該桿體32同樣呈三角形型態的設置。Furthermore, the
參閱圖3、圖4鎖合時,利用該鑽鎖部34先抵頂於物件(圖中未示)上,並施予該螺頭31一旋轉扭力,進而連動該鑽鎖部34於該物件上進行鑽鎖,同時帶動該等螺牙33隨該鑽鎖部34螺入該物件內時同時產生切削,此時,藉由該每一弧接面332皆呈尖銳角形態的設置,得以有利在旋動過程以快速方式使該弧切部334接觸到該物件上,並且對該物件產生銳利切削,同時更可藉由該等弧接面332所形成之尖銳的特殊螺牙設計,進而使該螺牙33與該物件呈穩固的囓合,以達防鬆動,且再加上任二該弧接面332間所連接之該牙面331小於該螺牙33外徑配合,與位於該二接點333間之該弧切部334所形成的弧度,其係以不超過該最大螺牙半徑r2的四分之一的設置,以使該等牙面331隨該等弧切部334在切削過程中不會過度與該物件產生相互摩擦,同時更可使該等螺牙33間具有較多餘空間供切屑容置,以降低鎖合扭力,且亦可免除切屑堆積而形成裂材之情事發生,當然,將圖6所示之該第一軸線α2相對該縱軸α1呈繞旋延伸的設置,藉此可使該等螺牙33以漸進接續方式擠壓鑽鎖切削該物件,藉此亦能有效降低鎖合扭力、阻力與增進鎖合效率等功效;是以,在鎖合過程中,除能提升該緊固件3之切削能力外,更能增加鎖合速度,且避免於鎖合受力時產生裂材之情事,進而達到降低鎖合阻力、扭力及有效增進鎖合效率等功效。3 and 4 when locking, the
參閱圖7、圖8,本發明之第二較佳實施例,其仍包含有螺頭31、桿體32、螺牙33及鑽鎖部34等要件;特別的是,在本實施例中該桿體32為具有四個桿體面321,以使該桿體32為四角形之多角型態設置,同時位於該每一端角面322上至該端角點323所形成之弧度,其係為不超過該最大桿體半徑r1之四分之一,至於,該每一螺牙33的牙面331相對該桿體面321呈相等數量設置,即為該等螺牙33亦對應該桿體32同樣呈四角形型態設置,以使該桿體32與該等螺牙33因為呈四角形型態而具有特殊多面向的設置,同時該鑽鎖部34亦隨該桿體32的四角形態樣而呈菱形態樣的尖尾設置(請參圖9所示),特別的是,前述該鑽鎖部34的成型可以透過一牙板的加工方式直接輾壓成型出(圖中未示)。Referring to Figures 7 and 8, the second preferred embodiment of the present invention still includes the
是以,鎖合時,同樣施予一扭力以連動該鑽鎖部34對該物件(圖中未示)進行鑽鎖作業,且同步帶動該等螺牙33鎖入該物件內,此時鑒由該桿體32延伸至該鑽鎖部34呈四角態樣設計,藉此得以使該先行達到鎖合的定位效果,而後再由該桿體32對應該螺牙33之弧切部334具有相同形態之該端角點323的配合設置,除利用該等螺牙33於第一時間達到快速、省力旋鎖進入該物件內外,同時利用該桿體32之桿體面321、螺牙33之牙面331所形成之特殊多面向的設計,以使該桿體32、螺牙33與該物件間因而形成有較多之容屑空間可供切屑容置甚至向外排出,所以該切屑不會因無法順暢排出而受到擠壓,而有鎖合扭力增加的情事產生,藉以有效避免因切屑堆疊與擠壓而產生裂材之缺失。Therefore, when locking, a torsion force is also applied to link the drill and
參閱圖10及圖11,本發明第三較佳實施例,其仍包含有與第一實施例所述相同之構件,其差異在於:該等螺牙33係連續相接以呈密集狀繞設於該桿體32上並延伸至該鑽鎖部34處,以使該桿體32呈不顯露態樣設置,同時該每一螺牙33繞設於該桿體32上的繞設係採正斜方式設置,當然亦該等螺牙33亦可採逆斜方式繞設於該桿體32上,即如圖12所示;是以,當該緊固件3進行鎖設時,利用該等螺牙33與該桿體32的多邊形設置,俾利藉由該緊固件3螺入時來導引該等弧切部334對鎖合之物件產生穩固的囓合,同時透過該等螺牙33所呈的密集式的連續相接設計,同時亦同樣能增加鎖合速度,以有效增進鎖合穩固等功效。10 and 11, the third preferred embodiment of the present invention still includes the same components as those described in the first embodiment, the difference is that the
參閱圖13,本發明第四較佳實施例,其仍包含有螺頭31、桿體32、鑽鎖部34及複數螺牙33等要件,特別的是,該桿體32在相同位置之端角點323相互串聯形成有一第二軸線α3,且該第二軸線α3相對該縱軸α1呈繞旋延伸的設置,而該第一軸線α2之繞旋模式與該二軸線α3之繞旋模式呈不同設置;是以,進行鎖設時可先透過該等弧切部334及端角點323排列相互串聯所形成之第一軸線α2與第二軸線α3之不同繞旋設置,俾利用以漸進接續方式擠壓鑽鎖切削該物件,藉此能有效先降低鎖合初期的扭力、阻力,而再利用該桿體32所呈繞旋設置有效增進切削速度及切屑向外排出速度,如此藉由該鎖固件3之該桿體32與該螺牙33同時皆為雙繞旋所構成之具有特殊形態的整體設置,使該桿體32無論與相對之該等弧切部334串聯所形成之旋繞模式為何,皆得以於鎖設切削之過程中達到切屑向外排出的不同排屑速率,同時亦與該物件產生不同的嵌合鎖設定位效果,致使該緊固件3沉入該物件中後,得以形成有效的穩固定位等功效。Referring to FIG. 13, the fourth preferred embodiment of the present invention still includes a

參閱圖15、圖16,本發明第六較佳實施例,其仍包含有螺頭31、桿體32、鑽鎖部34及複數螺牙33等要件,特別的是,該桿體32可區分為一第一桿區F1,以及一位於該第一桿區F1相與該螺頭31間之第二桿區F2,其中,位於該第一桿區F1中之該桿體32的每一端角面322另具有一向外凸伸之切割刃324,且該切割刃324係由至少二切割面325相接而成,且該二切割面325向外延伸交匯形成有一介於20~60度間之銳角型態的第三夾角θ3設置,且該第三夾角θ3不超過60度,而位於該第一桿體區F1中之該桿體32在相同位置之該等切割刃324相互串聯所形成有一第三軸線α4,該第三軸線α4相對該縱軸α1呈繞旋延伸設置,同時該切割刃324以該縱軸α1為基準向該二切割面325相接處延伸有一假想線H,以使該切割刃324之假想線H與該螺牙33之假想線B間因該第三軸線α4的繞旋關係而形成有一不超過45度的第四夾角θ4設置,且該第三軸線α4的繞旋方向與該緊固件3之旋鎖方向相同,而位於該第二桿區F2中之該桿體32在相同位置之該等端角點323相互串聯所形有一之第四軸線α5,該第四軸線α5則與該第一軸線α2呈平行的設置,當然,亦可如圖17、圖18之第七實施例所示,該第三軸線α4之繞旋方向與該緊固件3之旋鎖方向呈相反,而該第四軸線α5則與該第一軸線α2呈平行的設置;故,鎖合時,藉由該鑽鎖部34處之等螺牙33先以漸進接續方式擠壓鑽鎖切削該物件,藉此能有效降低鎖合扭力、阻力,同時透過該第一桿區F1呈旋繞設置,利用向外凸設之該等切割刃324的設計,以輔助鎖合時之過多纏繞於該桿體32上的纖維予以切削,以發揮該螺牙33與部分該桿體32的相互配合有效多重切削效果,如此得以使初步鎖合時較為省力外且又可增加鎖合速度,而後再導引串聯排列與該第四軸線α5形成之平行設置的該等螺牙33,接續進行快速切削,透過該桿體32之多邊型態藉以達到可供大量切屑容置與排出,因此該緊固件3利用不同形態之該桿體32與該等螺牙33所構成之整體設置,有利在鎖設時得以與物件(圖中位示)達到不同緊貼嵌合的穩定定位功效,以避免鬆脫,因此不論鎖設的物件材質為何其仍具有穩固鎖合等功效。15 and 16, the sixth preferred embodiment of the present invention still includes a
參閱圖19,本發明第八較佳實施例,其仍包含有螺頭31、桿體32、螺牙33及鑽鎖部34等主要構件;特別的是,本實施例在於該桿體32上設有一無螺牙區326,以使該等螺牙33因該無螺牙區326的形成而被區隔分成為第一螺牙E1、第二螺牙E2設置;因此,進行鎖合時,即先由該鑽鎖部34預先穩固定位於該物件上,而後即由該第一螺牙E1以快速切削方式進入該物件,同時切削時產生的切屑便會順由該第一螺牙E1間進入該無螺牙區326處,此時透過該無螺牙區326的無阻隔作用以進一步加速切屑往該第二螺牙E2間向外排出,如此得以有效減少鎖合初期產生的切屑擠壓與囤積,進而降低鎖合時產生的扭力以加速鎖合速度,而後該第二螺牙E2便會接續該第一螺牙E1的導引進入該物件中,接續進行鎖合的切削,俾使該緊固件3直至沉入該物件中後,得以形成有效的穩固定位等功效。19, the eighth preferred embodiment of the present invention still includes the main components such as the
