Abstract
一種螺絲頭的改進,尤指針對先前專利案TWM436104的實用性與進步性的進行提昇,使螺絲頭在螺旋沉入工作物時更有效的產生切屑、容屑與內壓殘屑的作用以及有效避免螺絲頭貼平工作物表面時頭部周圍產生攏起的現象;該螺絲頭的改進是在螺絲頭錐狀頸部設置有一體成型至少一個向內凹入螺絲頭錐狀頸部的條狀凹槽,在凹槽的兩側邊具有至少一個向側邊延伸的刀片,該刀片係一體成型向外凸出在螺絲頭錐狀頸部的表面,且凹槽兩側邊的刀片與螺絲頭的軸心線間具有一垂直或非垂直夾角,藉至少一個凹槽的設置以及數段間續螺旋排列的刀片或數段間續非螺旋排列的刀片,達到具有更銳利的輕易裁切木材纖維的能力以及凹槽較充裕的容屑空間,確實使螺絲頭的沉入更省力,工作物表面平整不攏起。 An improvement of the screw head, especially the improvement of the practicability and progress of the previous patent TWM436104, so that the screw head can more effectively generate chips, contain chips and internal pressure residues and effectively To avoid the phenomenon of curling up around the head when the screw head is flattened on the surface of the work object; the improvement of the screw head is that the conical neck of the screw head is provided with at least one strip that is inwardly recessed into the conical neck of the screw head. The groove has at least one blade extending sideways on both sides of the groove. The blade is integrally formed and protrudes outward on the surface of the screw head conical neck, and the blades on both sides of the groove and the screw head There is a vertical or non-perpendicular angle between the axis lines, and by setting at least one groove and several sections of intermittent helical blades or several intervals of non-helical blades, it is possible to achieve a sharper and easier cutting of wood fibers. The ability and the ample chip space in the groove do make the sinking of the screw head more labor-saving, and the surface of the work object is flat and not piled up.
Description
一種螺絲頭的改進,尤指在螺絲頭錐狀頸部設置有一體成型至少一個向內凹入螺絲頭錐狀頸部的條狀凹槽,在凹槽的兩側邊具有至少一個向側邊延伸的刀片,該刀片係一體成型向外凸出在螺絲頭錐狀頸部的表面,且凹槽兩側邊的刀片與螺絲頭的軸心線間具有一垂直或非垂直夾角。 An improvement of a screw head, especially at least one strip-shaped groove that is inwardly recessed into the conical neck of the screw head is integrally formed on the conical neck of the screw head, and at least one sideward edge is provided on both sides of the groove The extended blade is integrally formed and protrudes outward on the surface of the conical neck of the screw head, and there is a vertical or non-perpendicular angle between the blades on both sides of the groove and the axis line of the screw head.
在螺絲的螺絲頭頸部設置至少一個以上旋轉360度以上的螺旋凸肋以及螺旋凸肋形成螺絲刀刃的技術,為本案創作人早期技術創作的專利核准案TWM436104的技術特徵,藉由該早期技術創作能達到預期的螺絲頭沉入工作物時的螺絲孔木材纖維毛邊殘屑的產生或突露,以取得工作物螺絲孔周邊的平整乾淨效果。 The technology of setting at least one helical rib that rotates more than 360 degrees on the neck of the screw head and the helical rib to form a screw blade is the technical feature of the patent approval TWM436104 created by the author of this case in the early technology. It can achieve the expected generation or exposure of the wood fiber burr debris in the screw hole when the screw head sinks into the work object, so as to obtain a smooth and clean effect around the screw hole of the work object.
但在實際使用效益上存在如下待改進的缺點: However, there are the following shortcomings to be improved in actual use benefits:
(1)已知的早期技術創作TWM436104螺絲頭頸部所具備的至少一個以上旋轉360度以上的螺旋凸肋,在螺絲頭沉入工作物時,因連續至少360度的螺旋刀刃對木材纖維的裁切易產生切割不徹底,所以對螺旋刀刃的切割效果造成影響。 (1) The known early technological creation TWM436104 screw head neck has at least one spiral convex rib that rotates more than 360 degrees. Cutting is easy to produce incomplete cutting, so it affects the cutting effect of the spiral blade.
(2)由於已知的早期技術創作TWM436104螺絲頭頸部較缺乏切割後殘屑及未切割徹底的殘屑容納空間,會產生螺絲刀刃切割效果不盡快速,而且 擁擠的殘屑亦造成螺絲頭沉入工作物的較大阻力。 (2) Due to the known early technological creation TWM436104 screw head neck lacks cutting debris and uncut debris accommodation space, the cutting effect of the screwdriver blade will not be fast enough, and Crowded debris also causes greater resistance for the screw head to sink into the work object.
(3)由於已知的早期技術創作TWM436104螺旋刀刃的切割效果有限以及缺乏切割後殘屑及未切割徹底的殘屑容納空間,所以螺絲頭沉入工作物時無法達到理想的輕巧省力。 (3) Due to the limited cutting effect of the known early technology creation TWM436104 helical blade and the lack of cutting debris and uncut debris accommodation space, the ideal lightness and labor saving cannot be achieved when the screw head sinks into the work object.
(4)由於螺絲頭頸部較缺乏切割後殘屑及未切割徹底的殘屑容納空間,致使過大的殘屑擠壓易產生螺絲頭貼平工作物表面時螺絲頭頭部周圍的工作物表面產生攏起的現象。 (4) Since the neck of the screw head lacks space for cutting debris and uncut debris, excessive debris extrusion is likely to cause the surface of the working object around the screw head to flatten the surface of the working object when the screw head is flattened. The phenomenon of gathering.
所以本案創作人早期的技術創作確實有再改進的必要,以有效提高專利技術創作的實際實用進步性與產業利用性。 Therefore, it is indeed necessary to improve the early technical creation of the creator of this case, so as to effectively improve the actual practical progress and industrial utilization of the patented technical creation.
本案創作「螺絲頭的改進」其創作目的在於: The purpose of the creation of "Screw Head Improvement" in this case is to:
(1)有效改進早期技術創作TWM436104在螺絲頭沉入工作物時,因連續至少360度的螺旋刀刃對木材纖維的裁切易產生切割不徹底的缺點。 (1) Effectively improve the early technical creation TWM436104, when the screw head sinks into the work object, the cutting of wood fibers by the continuous at least 360-degree spiral blade is prone to incomplete cutting.
(2)有效改進早期技術創作TWM436104由於螺絲頭頸部缺乏切割後殘屑及未切割徹底的殘屑容納空間所造成螺絲頭沉入工作物的較大阻力。 (2) Effectively improve the early technical creation TWM436104. Due to the lack of space for the debris after cutting and the debris that has not been cut thoroughly in the neck of the screw head, the screw head has a large resistance to sinking into the work object.
(3)有效改進早期技術創作TWM436104在螺絲頭沉入工作物時無法達到理想的輕巧省力的缺點。 (3) Effectively improve the shortcoming that the early technical creation TWM436104 cannot achieve the ideal lightness and labor saving when the screw head sinks into the work object.
(4)有效改進早期技術創作TWM436104由於螺絲頭頸部較缺乏切割後殘屑及未切割徹底的殘屑容納空間,致使過大的殘屑擠壓易產生螺絲頭貼平工作物表面時螺絲頭頭部周圍的工作物表面產生攏起的現象。 (4) Effectively improve the early technical creation TWM436104. Because the neck of the screw head lacks the space for the debris after cutting and the debris that has not been cut thoroughly, resulting in excessive debris extrusion, it is easy to produce the screw head when the screw head is flattened on the surface of the work. The surface of the surrounding work object is gathered up.
