具低阻力、快速鑽鎖之緊固件Fastener with low resistance and fast drilling lock

本新型是有關於一種緊固件之設計，特別是指一種具低阻力、快速鑽鎖之緊固件。The present invention relates to the design of a fastener, and more particularly to a fastener with low resistance and fast drilling lock.

參閱圖1、圖2，習知緊固件1包含有一螺頭11，一由該螺頭11向外延伸之桿體12，一相反該螺頭11且設於該桿體12另一端之鎖合部13，以及複數環設於該桿體12上之螺牙14；是以，進行施工時，該螺頭11得以在一工具(圖中未示)的帶動下，鑽鎖進入一物件2中，同時該等螺牙14即在該鎖合部13受到該工具的旋轉帶動下，逐漸一併螺入該物件2內，如此即達到鎖合定位的效果。Referring to FIG. 1 and FIG. 2, the conventional fastener 1 includes a screw head 11, a rod body 12 extending outward from the screw head 11, and a screw body 11 opposite to the screw head 11 and disposed at the other end of the rod body 12. a portion 13 and a plurality of threads 14 disposed on the rod body 12; that is, when the construction is performed, the screw head 11 is driven by a tool (not shown) to enter the object 2 At the same time, the thread 14 is screwed into the object 2 under the rotation of the tool 13 , so that the locking positioning effect is achieved.

惟，使用後發現，鑒於習知該緊固件1之該螺牙14係呈圓形態樣且環設於該桿體12上，導致該緊固件1於鑽切過程中，該螺牙14之整個周緣會與該物件2之內壁面形成緊密接觸，不但會使該螺牙14與該物件2間之摩擦力增加外，同時於鑽鎖過程中所形成之切屑易積存於內而無法有效向外排出，此時將會造成該緊固件1之鎖合阻力增加與鎖合扭大幅提升外，相對地在該緊固件1後續的旋鎖作業上，則必需再施以較大之旋轉扭力，方得以帶動該緊固件1的持續螺鎖進入，如此不但會造成鎖合速率降低外，同時亦因鎖合速率變慢而導致過多之切屑囤積於該物件2內，且更會造成囤積於內之切屑相互擠壓而形成往外擴散，進而導致該物件2具有裂材之情事產生，故不但無法有效達道到快速鑽鎖效果外，同時更會影響該緊固件的鎖合定位，實有待改善。However, it has been found that, in view of the conventional use, the thread 14 of the fastener 1 has a circular shape and is looped on the shaft 12, resulting in the entire fastener 14 during the cutting process. The peripheral edge will form close contact with the inner wall surface of the object 2, which not only increases the friction between the thread 14 and the object 2, but also the chips formed during the drilling and locking process are easily accumulated and cannot be effectively outward. Exhaust, at this time, the locking resistance of the fastener 1 is increased and the locking twist is greatly increased. In addition, in the subsequent twisting operation of the fastener 1, it is necessary to apply a large rotating torque. The continuous threading of the fastener 1 can be driven, which not only causes the locking rate to decrease, but also causes excessive swarf to accumulate in the object 2 due to the slow locking rate, and further causes hoarding therein. The chips are squeezed to each other to form an outward diffusion, which in turn causes the object 2 to have a cracked material. Therefore, not only can the effect of the fast drilling and locking effect be effectively achieved, but also the locking position of the fastener is affected, which needs to be improved.

因此，本新型之目的，是在提供一種具低阻力、快速鑽鎖之緊固件，其可提升鎖合速率、降低鎖合阻力，以確實避免鎖合時發生裂材情事。Therefore, the purpose of the present invention is to provide a fastener with low resistance and fast drilling lock, which can improve the locking rate and reduce the locking resistance, so as to avoid the occurrence of cracking during the locking.

於是，本新型具低阻力、快速鑽鎖之緊固件利用螺牙至少由二不對稱之弧切面組成，並且該任二弧切面相接處形成有一切刃，以及該每一弧切面上開設有鋸齒，同時再搭配由該鎖合部之鑽尖往該螺頭方向延伸設置至少有二切肋，故鎖合初期，該等切肋得以漸進旋切方式，以輔助該鎖合部鎖入時可達避免裂材情事外，同時鑽鎖中再藉由該每一螺牙具有二不對稱之切面與鋸齒的配合設置，如此不但可以減少該等螺牙鎖入時與鎖合物間產生相互摩擦外，且更能增加切削效果，有效加強防止裂材功效，以及具有大幅降低鎖合阻力，進而提升加速鎖合效率功效。Therefore, the fastener with low resistance and fast drilling lock of the present invention is composed of at least two asymmetric arc cutting faces, and all the cutting edges are formed at the intersection of the two arc cutting faces, and each arc cutting surface is opened. The serrations are combined with the drill tip of the locking portion to extend at least two ribs in the direction of the screw head. Therefore, in the initial stage of the locking, the ribs are gradually rotated and cut to assist the locking portion when locked. In addition to avoiding the cracking of the material, the drilling lock has a combination of two asymmetric cutting surfaces and serrations, so that not only can the mutual locking of the thread and the lock compound be generated. In addition to friction, it can increase the cutting effect, effectively strengthen the effect of preventing cracking, and greatly reduce the locking resistance, thereby improving the efficiency of the acceleration locking.

有關本新型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 above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

參閱圖3，本新型第一較佳實施例，包含有一桿體31，一設於該桿體31一端之螺頭32，一相反該螺頭32且設於該桿體31另一端之鎖合部33，複數螺旋環設於該桿體31上且延伸至該鎖合部33之螺牙34，以及至少二形成於該鎖合部33上之切肋35；其中，該每一螺牙34至少由二不對稱之弧切面341組成，而該任二弧切面341相接處形成有一切刃342，以及該每一弧切面341上開設有複數鋸齒343，而前述鑒於該等弧切面341係成不對稱之設置，因此該每一螺牙34則會呈現出非一正圓態樣之設置，同時在該每一螺牙34上之該等弧切面341於設計上，則可依實際需求設計呈具有三個以上之該弧切面341，在本實施例中係以具有三個該弧切面341且呈不對稱之設置為例說明；另，該每一切肋35係由近該鎖合部33之鑽尖331處往該螺頭32方向延伸之設置，當然該等切肋35的設置可如圖5所示，係由該鑽尖331處往該螺頭32方向延伸，同時設於該鎖合部33上之該切肋35亦可呈具三個以上之設置，即如圖3中係以同時具該三個切肋35、該三個弧切面341的為例加以說明。Referring to FIG. 3, a first preferred embodiment of the present invention includes a rod body 31, a screw head 32 disposed at one end of the rod body 31, and a screw body 32 opposite to the screw head 32 and disposed at the other end of the rod body 31. a portion 33, a plurality of helical rings are disposed on the rod body 31 and extend to the threading portion 34 of the locking portion 33, and at least two cutting ribs 35 formed on the locking portion 33; wherein each thread 34 At least two asymmetric arc cut faces 341 are formed, and the intersection of the two arc cut faces 341 is formed with all the blades 342, and each of the arc cut faces 341 is provided with a plurality of serrations 343, and the aforementioned arc cut face 341 is The asymmetry is set, so that each of the screws 34 will be arranged in a non-circular shape, and the arc cuts 341 on each of the screws 34 are designed to meet actual needs. The design has three or more of the arc cut surfaces 341. In the embodiment, the three arc cut surfaces 341 are arranged in an asymmetrical manner as an example. In addition, each of the ribs 35 is adjacent to the lock portion. 33 drill point 331 extends toward the direction of the screw head 32, of course, the arrangement of the ribs 35 can be as shown in FIG. The tip 331 extends toward the screw head 32, and the cutting rib 35 provided on the latching portion 33 can also have three or more arrangements, that is, the three ribs 35 are simultaneously provided in FIG. The three arc cut surfaces 341 are described as an example.

參閱圖3、圖4，鎖合時，因鑒於該等切肋35係由近該鑽尖331往該螺頭32處方向延伸，故當該鎖合部33頂抵於一鎖合物4上後，即於該螺頭32上施予一旋轉扭力，先由該鑽尖331與該鎖合物4接觸，同時在該鑽尖331鑽鎖過程中即會產生切屑與纖維，這時便可利用分設於該鑽尖331處之該等切肋35之配合設置，配合在旋轉扭力的帶動下得以呈旋切漸進之方式，以輔助該鎖合部33斬切鑽鎖時產生之纖維，故可使得該鎖合部於鎖入可避免受到過多纖維纏繞而發生裂材，且更可使該等螺牙34受到該鎖合部33的帶動在逐一螺合進入該鎖合物4內的過程中，得以利用該每一切刃342在接觸該鎖合物4之際即同步進行切削，這時利用不對稱該等弧切面341上之複數該鋸齒343的特殊設置，以快速有效斬切部份纏繞於該弧切面341上之切屑，不但可以減少該等螺牙34鎖入與鎖合之該鎖合物4之間產生相互磨擦外，更能有效避免堆積過多之切屑所會產生之擠壓而造成裂材，使得鎖合阻力得以降低，大幅提升、加速鎖合效率功效。Referring to FIG. 3 and FIG. 4, when the locking ribs 35 extend from the drill point 331 toward the screw head 32, the locking portion 33 abuts against a lock compound 4. Then, a rotating torque is applied to the screw head 32, and the drill tip 331 is first contacted with the lock compound 4, and chips and fibers are generated during the drilling and locking process of the drill tip 331. The matching arrangement of the cutting ribs 35 disposed at the drill point 331 is matched with the rotation torsion force to be rotated and progressively extended to assist the locking portion 33 to cut the fiber generated when the drill is locked. The locking portion can be prevented from being entangled by excessive fiber entanglement to cause cracking, and the thread 34 can be screwed into the lock compound 4 one by one by the locking portion 33. In this case, each of the blades 342 can be synchronously cut while contacting the lock compound 4, and the special setting of the plurality of serrations 343 on the arc-shaped cut surfaces 341 is utilized to quickly and effectively cut the partial winding. The chips on the arc cut surface 341 can not only reduce the lock between the lock teeth 34 and the lock compound 4 In addition to mutual friction, it is more effective to avoid the crushing of the squeezing caused by the excessive accumulation of chips, so that the locking resistance can be reduced, and the efficiency of the locking efficiency can be greatly improved and accelerated.

接續前述，再者，更鑒於該等螺牙34具有不對稱之該弧切面341之設計，可使該等螺牙34間能有較多之容屑空間可供切屑排放與容置，有效加強防止裂材外，更可使該緊固件3與該鎖合物4間形成較佳之鎖合緊固力，俾使該緊固件3在完全鑽鎖進入該鎖合物4後，不會受外力因素影響而有自動旋退之缺失產生；因此，先藉由該切肋35以輔助該鎖合部33於初期鑽鎖時得以避免發生裂材外，同時再利用不對稱該等弧切面341上具有該等鋸齒343的配合設計，藉以有效提升該緊固件3之切削能力，同時亦能降低鎖合摩擦力、阻力與扭力，以加速鎖合速率，更能避免受到外在因素影響而產生自動旋退之缺失，進而提升加速鎖合效率與定位效果。In addition, in view of the fact that the screw teeth 34 have asymmetrical design of the arc cutting surface 341, the screw teeth 34 can have more space for chip discharge and storage, effectively strengthening In addition to preventing cracking, the fastener 3 and the lock compound 4 can be formed into a better locking fastening force, so that the fastener 3 is not subjected to external force after fully drilling into the lock compound 4. The factor is affected and there is a lack of automatic retreat; therefore, the rib 35 is first used to assist the locking portion 33 in the initial drilling lock to avoid cracking, and at the same time, the asymmetric arc surface 341 is reused. The matching design with the serrations 343 can effectively improve the cutting ability of the fastener 3, and at the same time reduce the frictional force, the resistance and the torsion force, thereby speeding up the locking rate and avoiding the influence of external factors. The lack of retreat, thereby improving the efficiency of acceleration and locking and positioning.

參閱圖6、圖7，本新型第二較佳實施例，其與第一實施例所述相同，該緊固件3仍包含有桿體31、螺頭32、鎖合部33、螺牙34及切肋35等構件；特別是，在本實施例中該每一弧切面341之鋸齒343間至少開設有一深至該螺牙34之牙底的割溝344，同時該每一弧切面341上可開設有二或三個該割溝344之設置(圖中未示)，藉以增進該緊固件3鑽鎖時的排屑空間；是以，進行鑽鎖時，除利用該等切肋35輔助該鎖合部33達到快速鑽鎖進入該鎖合物4，不但可有效避免鑽鎖初期之裂材產生外，同時更能藉由該每一螺牙34上之該切刃342帶動該等鋸齒343斬切纏繞於該等弧切面341上之切屑，同時更能利用開設於該等鋸齒343間之該割溝344配合，來有效協助該切刃342斬切所形成之切屑向外排出外，更可供部份切屑容置於其中，如此更能大大降低鎖合扭力、阻力以及有效增進鎖合速率等功效。Referring to FIG. 6 and FIG. 7 , the second preferred embodiment of the present invention is the same as that of the first embodiment. The fastener 3 still includes a rod body 31 , a screw head 32 , a locking portion 33 , a thread 34 and The ribs 35 and the like; in particular, in the embodiment, at least one slit 344 is formed between the serrations 343 of each of the arc-cut faces 341 and deep to the root of the screw 34, and the arc-cut surface 341 is The arrangement of two or three of the cutting grooves 344 (not shown) is opened to improve the chip evacuation space when the fastener 3 is drilled; that is, when the drilling is performed, the cutting ribs 35 are used to assist the The locking portion 33 reaches the fast drilling lock and enters the locking compound 4, which not only can effectively prevent the cracking material from being generated in the initial stage of the drilling lock, but also can drive the saw teeth 343 by the cutting edge 342 on each thread 34. Cutting the chips wound on the arc-shaped cut surfaces 341, and at the same time, the cutting grooves 344 formed between the serrations 343 can be used to cooperate to effectively assist the cutting edges of the cutting edges 342 to be outwardly discharged. Part of the chip can be placed in it, which can greatly reduce the locking torque, resistance and effective increase of the locking rate.

參閱圖8，本新型之第三較佳實施例，本實施例與前第一實施例差別在於：於該等螺牙34間另環設有一鉸切螺牙36，而該每一鉸切螺牙36係由不對稱且至少具有二切削面361所設置組成，同時該任二切削面361相接處形成有一刀刃362，且該每一切削面361上形成複數鋸齒363，而該鉸切螺牙36之外徑A2係小於該螺牙34之外徑A1，而前述環設於該等螺牙34間之該鉸切螺牙36亦可適時運用在該第二實施例上，即如圖9之第四較佳實施例所示，利用該等螺牙34與該等鉸切螺牙36於該桿體31上所構成之高低牙交錯的特殊設置，可使該緊固件3在鑽鎖過程中，更具有加速切屑、排屑效果，以減少切屑堆積，使得鎖合更具順暢性，以提升該緊固件3穩固鎖合定位效果。Referring to FIG. 8, in a third preferred embodiment of the present invention, the difference between the embodiment and the first embodiment is that a hinged screw 36 is further disposed between the threads 34, and each of the hinged screws The teeth 36 are composed of asymmetrical and at least two cutting faces 361, and a cutting edge 362 is formed at the intersection of the two cutting faces 361, and a plurality of serrations 363 are formed on each cutting surface 361, and the reaming snail is formed on the cutting surface 361. The outer diameter A2 of the tooth 36 is smaller than the outer diameter A1 of the screw 34, and the reaming screw 36 disposed between the threads 34 can be used in the second embodiment as appropriate. According to the fourth preferred embodiment of the present invention, the fasteners 3 can be drilled by the special arrangement of the threaded teeth 34 and the high and low teeth of the hinged threads 36 on the rod body 31. In the process, it has the effect of accelerating chip and chip removal to reduce chip accumulation, which makes the lock more smooth, so as to improve the stable locking and positioning effect of the fastener 3.

歸納前述，本新型具低阻力、快速鑽鎖之緊固件利用該鎖合部之鑽尖處具有至少二個之切肋的設計，得以在鎖合初期時輔助該鎖合部鎖入時避免發生裂材，再利用該等螺牙具有複數鋸齒且呈不對稱之弧切面的配合特殊設計，不但可以減少該等螺牙鎖入時與鎖合物間產生相互摩擦外，且更能增加切削效果，使得鎖合阻力可有效降低，以提升加速鎖合效率等功效，故確實能達到本新型之目的。In summary, the novel fastener with low resistance and fast drilling lock has a design with at least two ribs at the drill tip of the locking portion, so as to avoid the occurrence of locking when the locking portion is locked in the initial stage of locking. The cracked material, and the special design of the screw having a plurality of serrations and an asymmetrical arc cut surface can not only reduce the mutual friction between the plug and the lock compound, but also increase the cutting effect. Therefore, the locking resistance can be effectively reduced to improve the efficiency of the acceleration locking, so that the purpose of the novel can be achieved.
