Description
本創作係有關於一種螺絲，尤指一種具有不同螺距之螺牙段，及於螺牙段上設有斷牙區段，而可更順利進行鎖固之木螺絲結構改良。This creation relates to a kind of screw, especially a screw segment with different pitches, and a broken tooth segment on the screw segment, which can improve the structural improvement of the locking screw.
按，螺絲的種類繁多，一般用於塑膠、木材等非金屬物件鎖固時，大多是採用木螺絲，如第一圖所示，為一種習知木螺絲結構，該習知木螺絲10包含：一螺頭101及一桿體102，該螺頭101係用以與鎖固工具相接，該桿體102係由該螺頭101延伸出，該桿體102遠離該螺頭101之一端設置一尖錐部103，該桿體102周緣設有由該尖錐部103往該螺頭101方向螺旋環繞之螺牙104，使用時，利用該尖錐部103鑽設物件，配合該螺牙104進行切削旋鎖，而達到鎖固物件的效果。然而，該種習知木螺絲10的螺牙104係單一螺距，並為顧及鎖固速度其螺距需具有一定距離，故當該木螺絲10以其尖錐部103剛開始鑽設物件時，螺牙104無法快速咬入物件內，以致定位不易而容易有鎖固點移位的問題，以及容易發生空轉的現象，令使用者得費更多的力氣和時間方能將木螺絲10與物件作鎖固，殊不理想。Press, a variety of screws, generally used for plastic, wood and other non-metallic objects when locking, mostly using wood screws, as shown in the first figure, is a conventional wood screw structure, the conventional wood screw 10 contains: a screw head 101 and a rod body 102 for connecting with a locking tool, the rod body 102 is extended by the screw head 101, and the rod body 102 is disposed away from one end of the screw head 101. The tapered portion 103 is provided with a thread 104 spirally surrounding the screw head 101 by the tapered portion 103. In use, the object is drilled by the tapered portion 103, and the screw 104 is engaged with the screw 104. Cutting the twist lock to achieve the effect of locking the object. However, the thread 104 of the conventional wood screw 10 is a single pitch, and the pitch needs to have a certain distance in consideration of the locking speed, so when the wood screw 10 starts to drill the object with the taper portion 103, the screw The tooth 104 cannot be quickly bitten into the object, so that the positioning is not easy and the problem of the displacement of the locking point is easy, and the phenomenon of idling is easy to occur, so that the user can spend more effort and time to make the wood screw 10 and the object. Locking is not ideal.
如公告第M407970號「木螺絲」新型專利，為另一種習知木螺絲結構，包含：一螺頭及一桿體，該桿體上設有第一螺紋、第二螺紋及第三螺紋，該第一螺紋、第二螺紋及第三螺紋各具有不同之功能，而得以使木螺絲快速省力 與物件作鎖固。然而，因其第二螺紋的螺旋方向係與第三螺紋的螺旋方向相反，且該第一、第二及第三螺紋彼此間互不相連，故鎖固物件時，易因排屑不良而阻塞，造成擠壓作用及摩擦阻力，進而致使木螺絲鎖入過程不順暢甚至導致崩牙或物件裂開之情形。For example, the new patent of "wood screw" in the publication No. M407970 is another conventional wood screw structure, comprising: a screw head and a rod body, wherein the rod body is provided with a first thread, a second thread and a third thread, The first thread, the second thread and the third thread each have different functions, so that the wood screw can be quickly and labor-saving Lock with the object. However, since the spiral direction of the second thread is opposite to the spiral direction of the third thread, and the first, second, and third threads are not connected to each other, the object is easily blocked due to poor chip removal when the object is locked. , causing the squeezing action and frictional resistance, which in turn causes the wood screw to lock into the process is not smooth or even cause the broken teeth or the object to crack.
如公告第M373415號「攻牙螺絲」新型專利，為又一種習知木螺絲結構，其主要係由一螺絲桿體之兩端各形成一施力部與一鑽頭部，該鑽頭部末端形成一尖端，該鑽頭部以及螺絲桿部形成一自該尖端向該施力部方向螺旋延伸之螺牙，以及自該鑽頭部末端向施力部方向延伸設有至少一導屑槽，而得以保持鑽頭部之剛性使攻入時更加穩固，以及增加攻入時之咬合力以增加切削效率，並使排屑過程更加順暢。然而，其需於螺牙成型後，另外再進行該導屑槽之銑削加工，如此不僅會多增加一道銑削加工程序，且在夾持加工時亦會有螺紋受損變形的情形發生，故製造成本高，不符合經濟效益。For example, the new patent of "Tapping Screw" in the announcement No. M373415 is another conventional wood screw structure, which mainly comprises a force applying portion and a drill portion at both ends of a screw rod body, and the end portion of the drill portion forms a a tip end, the drill portion and the screw shaft portion form a thread extending spirally from the tip end toward the urging portion, and at least one guide groove extending from the end of the drill portion toward the urging portion to maintain the drill portion The rigidity makes the penetration more stable, and increases the bite force during the attack to increase the cutting efficiency and make the chip removal process smoother. However, after the screw is formed, the milling of the chip guide groove is performed, so that not only a milling process is added, but also a thread deformation and deformation occurs during the clamping process, so that manufacturing is performed. High cost and not economical.
