具快速鎖設之螺絲Fast-locking screw

本新型是有關於一種螺絲，特別是指一種具快速鎖設之螺絲。The present invention relates to a screw, and more particularly to a screw with a quick lock.

参閱圖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，以及複數螺旋環設於該桿體12上之螺牙段13；其中，該桿體12末端形成有一鑽尖122之尖錐面121；另，該螺牙段13末端連接該鑽尖122，且該螺牙段13具有複數環設於該尖錐面121、桿體12上之螺牙131；故鎖合時，利用該鑽尖122抵住一物件2上，於該螺頭11上施予以一下壓及旋轉扭力，以連動該等螺牙13切削物件2，以逐漸帶動該桿體12螺入該物件2內，進而達到鎖合定位之效果。Referring to FIG. 1 and FIG. 2, the conventional screw 1 includes a screw head 11, a rod body 12 extending outward from the screw head 11, and a threaded portion 13 of the plurality of spiral rings disposed on the rod body 12; The tip end of the rod body 12 is formed with a tapered surface 121 of the drill tip 122. Further, the end of the threaded portion 13 is connected to the drill point 122, and the threaded portion 13 has a plurality of rings disposed on the tapered surface 121 and the rod body. The screw 131 on the 12; when the lock is engaged, the drill tip 122 is used to abut against an object 2, and the screw head 11 is subjected to a pressing force and a rotating torque to interlock the thread teeth 13 to cut the object 2 to The rod body 12 is gradually driven into the object 2 to achieve the effect of the locking positioning.

然，實際使用後發現，由於該等螺牙段13連接該鑽尖122，因此，當該螺絲1初始旋入時，排屑效果不佳外，同時該每一螺牙131係呈圓形繞於該桿體12上，使得切削過程中，該等螺牙121皆與該物件2呈緊密接觸，除造成該等螺牙121與物件2之摩擦力增加外，同時切削所產生之切屑易積存且無法順利排出該於該物件2外，如此將使該螺絲1 鎖合阻力增加，造成鎖合扭力大幅上升，加上該螺牙段12末端之螺牙121連接至該鑽尖122上，將更增加該螺絲1初始旋入物件2之阻力，故必須施予更大之鎖合扭力方可進行鎖合，導致鎖合速度亦會受到影響而降低外，同時當切屑囤積到一定程度後，也易造成切屑相互擠壓而形成向外擴壓之狀況，進而導致該物件2裂材等情事發生，實有待改進。However, after actual use, it is found that since the screw segments 13 are connected to the drill tip 122, when the screw 1 is initially screwed in, the chip removal effect is not good, and the screw 131 is circularly wound. The shank 121 is in close contact with the object 2 during the cutting process, except that the friction between the screw 121 and the object 2 is increased, and the chip generated by the cutting is easy to accumulate. And can not be smoothly discharged outside the object 2, so that the screw 1 will be The locking resistance increases, causing the locking torque to rise sharply, and the screw 121 at the end of the screw segment 12 is connected to the drill tip 122, which increases the resistance of the screw 1 initially screwed into the object 2, so it must be applied. The larger the locking torque can be locked, so that the locking speed will be affected and reduced. At the same time, when the chips are accumulated to a certain extent, the chips will be squeezed to each other to form an outward pressure-expanding condition. The situation that caused the object 2 to crack material, etc., needs to be improved.

因此，本新型之目的，是在提供一種具快速鎖設之螺絲，鎖合時可達到快速切削旋入、降低鎖合中物件裂材之情事外，同時鎖合後，亦具有防止螺絲旋退之效果。Therefore, the purpose of the present invention is to provide a screw with quick locking, which can achieve rapid cutting and screwing in the locking and reduce the cracking of the object in the locking state, and at the same time, the screw can be prevented from retreating after the locking. The effect.

於是，本新型具快速鎖設之螺絲，其包含有一螺頭，一由該螺頭向外延伸之桿體，複數螺旋環設於該桿體上之螺牙段，以及複數環設於該桿體上且位於任二螺牙間之凸塊；其中，該螺牙段並未連接至該桿體之尖錐面的鑽尖上，該螺牙段之每一螺牙斷面則形成至少二呈相對設置之弦切弧，以及分別設於該弦切弧間之連接弧，而前述所形成之該等弦切弧之弧形的中心點不與該桿體的中心相同，以使該螺牙呈現出非正圓型之型態；是以，故於鎖合過程中，可有效降低該螺牙與物件之接觸面積，藉以減少該螺牙與物件之摩擦力外，並且該凸塊將可斬切纏繞於該桿體上之物件纖維，進而達到快速鑚鎖進入該物件之效果外；再者，於鎖合後，該弦切弧與該等凸塊緊密結合於該物件上，而達到防止該螺 絲旋退、鬆脫之效果。Therefore, the present invention has a quick-locking screw, which comprises a screw head, a rod body extending outward from the screw head, a plurality of spiral rings disposed on the threaded portion of the rod body, and a plurality of rings disposed on the rod a bump on the body and located between any two threads; wherein the thread segment is not connected to the tip of the tapered surface of the rod body, and each thread section of the thread segment forms at least two Correspondingly arranged chord arcs, and connecting arcs respectively disposed between the chord arcs, and the center points of the arcs formed by the aforementioned chord arcs are not the same as the center of the shank, so that the snails The tooth exhibits a non-circular shape; therefore, during the locking process, the contact area between the screw and the object can be effectively reduced, thereby reducing the friction between the screw and the object, and the bump will The object fiber wound on the rod body can be cut and cut, thereby achieving the effect of quick shackle entering the object; further, after the lock, the string cutting arc and the protrusions are tightly coupled to the object, and Reach the snail The effect of silk retreating and loosening.
