Description
本發明係關於一種緊固件設計，特別是指一種具有抗拉力且防鬆退之緊固件。 The present invention relates to a fastener design, and more particularly to a fastener having tensile strength and anti-retraction.
參閱圖1至圖3，習知美國公開第20050186048號專利申請案螺絲1包含有一桿體11，一設於該桿體11上之螺頭12，一相反該螺頭12且設於該桿體11另一端之鎖合部13，以及複數環設於該桿體11上之螺牙14；其中，該等螺牙14上開設有複數相連之切口141，且於該每一螺牙14分別具有一由該桿體11向下延伸之上牙面142，與一由該桿體11向上延伸之下牙面143，以及一由該上、下牙面142、143交匯形成之牙峰夾角144，同時該牙峰夾角144所形成之頂點係交合出一頂角145，且該每一切口141形成一具切口夾角146的設置；是以，當該螺絲1進行鎖合作業時，便可利用該等切口141之旋削功能，以增加該等螺絲1斬切鎖合物件(圖中未示)作用，進而達到快速鎖合地功效。 Referring to FIG. 1 to FIG. 3, the screw 1 of the US Patent Publication No. 20050186048 includes a rod body 11, a screw head 12 disposed on the rod body 11, and a screw head 12 opposite thereto and disposed on the rod body. a latching portion 13 at the other end, and a thread 14 of the plurality of loops disposed on the rod body 11; wherein the threaded teeth 14 are provided with a plurality of connected slits 141, and each of the threaded teeth 14 has A shank 142 extending downward from the shank 11 and a lower surface 143 extending upward from the shank 11 and a peak angle 144 formed by the intersection of the upper and lower flank 142, 143. At the same time, the apex formed by the peak angle 144 intersects with a corner 145, and each of the slits 141 forms a setting of the slit angle 146. Therefore, when the screw 1 is engaged in locking cooperation, the screw can be utilized. The turning function of the slit 141 is used to increase the function of the screws 1 (not shown), thereby achieving the effect of quick-locking.
惟，實際使用後發現，當該等螺牙14旋切進入該鎖合物件內的過程中，雖可藉由該等切口141的設置來達到較 佳的切削效果，然而鑒於該等切口141之切口夾角146的角度大小與該等螺牙14之牙鋒夾角144大小，以及該桿體11等設計之因素，容易影響該螺絲1之實際鎖合效果，茲詳如下： However, after actual use, it is found that when the thread 14 is cut into the lock member, the setting of the slit 141 can be used to achieve A good cutting effect, however, in view of the angle between the angle of the notch angle 146 of the slits 141 and the angle 144 of the teeth of the screws 14, and the design factors of the rod 11 and the like, the actual locking of the screw 1 is easily affected. The effect is as follows:
1.易產生崩牙之缺失： 1. Easy to produce missing teeth:
鑒於該等螺牙14之切削能力係藉由該等切口夾角146之設置角度大小而產生不同之影響效果，亦即當該等切口夾角146之角度設置過小，以使該等螺牙14切削過程中在執行快速鎖合進入鎖合物件之作動時，該鎖合物件之纖維囚所具有之彈性回復力之特色，而無法有效進入該等切口141之中，導致該等切口141無法有效來輔助該等螺牙14旋削鎖合物件之功能，使得該等切口141所能供之切削功能有限，甚至無效果，且更無法導引該螺絲1得以確實攻入該鎖合物件內；反之，若該等切口角度146開設過大，則該等螺牙14之尺寸有可能會相對減小，反而更會因該切口角度146過大之因素而造成該等切口141之旋削能力不如該切口141較小之旋削能力，同時此尺寸相對較小之該螺牙14因其結構方面所呈較薄之原故，進而導致無法有效承受鎖合之扭力，進而容易有崩牙之情事產生，實有待改善。 In view of the fact that the cutting ability of the threads 14 is different by the angle of the angles of the incision angles 146, that is, when the angles of the incision angles 146 are set too small, the cutting process of the screws 14 is performed. When performing the quick-locking operation into the lock member, the fiber-retaining member of the lock member has the characteristic of elastic restoring force, and cannot effectively enter the slits 141, so that the slits 141 cannot be effectively assisted. The function of the screw 14 to rotate the lock member makes the cutting function 141 provide limited cutting function, even no effect, and it is impossible to guide the screw 1 to be surely tapped into the lock member; If the angles of the slits 146 are too large, the size of the threaded teeth 14 may be relatively reduced. On the contrary, the cutting ability of the slits 141 may be less than that of the slits 141 due to the excessive angle of the cutting angles 146. The turning ability, and the relatively small size of the screw 14 is thin due to its structure, thereby causing the torque to be unable to withstand the locking force, and thus the occurrence of a broken tooth is easy. needs to be improved.
2.無法降低鎖合扭力： 2. Can not reduce the locking torque:
由於為有效使該螺牙14順利成型出，因此皆是採用以牙板(圖中未示)於該桿體11上快速輾壓成型，是以在該螺牙14同步成型於該桿體11上的同時，即會同步導致該桿體11 上形成有凹凸不平狀，且因該等不平狀形成於該桿體11上，即會造成該螺絲1於鎖合過程中會有彎曲度與扭力不佳的情事產生，進而降低鎖合緊固力，且鎖合過程中更會造成該桿體11上之該等凹凸不平處無法持承受鎖合應力而呈過度扭轉、甚至有斷裂等缺失；且更因該螺絲1的鎖合效果受限於該等螺牙11之牙峰夾角設計之角度144大小影響，而有不同效果產生，亦即若該等螺牙14之牙峰夾角144過小，雖可使該等螺牙14具有較佳的切削能力，但如遇較堅硬之鎖合物件時，極易造成該等螺牙無法承受較大之旋入之扭力，而有損壞與鎖設不完成等缺失，反之，致使該等螺牙14之牙峰夾角144較大時，雖可使該等螺牙14具有較佳之承受扭力，但切削效果雖不如牙峰夾角144角度較小之該螺牙14，仍然會有鎖設不完全等情事產生，故造成使用上是有限制的，實需改進。 In order to effectively form the screw 14 smoothly, the squeegee (not shown) is rapidly formed on the rod body 11 so that the thread 14 is synchronously formed on the rod body 11 . At the same time, it will synchronously cause the rod body 11 The unevenness is formed on the rod, and the unevenness is formed on the rod body 11, which causes the screw 1 to have a degree of curvature and poor torque during the locking process, thereby reducing the locking and fastening. During the locking process, the unevenness on the rod body 11 may not be subjected to the locking stress and may be excessively twisted or even broken, etc.; and the locking effect of the screw 1 is limited. The effect of the angle 144 of the peak angle design of the thread 11 is different, and different effects are generated, that is, if the angle 144 of the tooth 14 of the thread 14 is too small, the thread 14 can be better. Cutting ability, but in the case of harder lock components, it is easy to cause the screw to not withstand the large screwing torque, but the damage and the lock are not completed, etc., and vice versa, causing the thread 14 When the angle 144 of the peak is large, the thread 14 can be better to withstand the torsion, but the thread 14 is not as good as the angle 14 of the angle 144, and the locking is still incomplete. It is produced, so there is a limit to the use, and it needs improvement.
因此，本發明之目的，是在提供一種緊固件，其具抗鎖合拉力與提升切削能力，更具有鎖合後防止鬆退等作用，進而達到快速鎖合定位之功效。 Therefore, the object of the present invention is to provide a fastener which has anti-locking tension and lifting cutting ability, and has the functions of preventing loosening after locking, thereby achieving the effect of quick locking positioning.

The requirements of the tip end, the drill tail, and the like (not shown) are not described in detail; in this embodiment, the diameter r1 of the first screw 34 is equal to the diameter r2 of the second screw 35, Of course, the diameter r1 of the first screw 34 can be set to be smaller than the diameter r2 of the second screw 35, as shown in FIG. 11 of the third preferred embodiment; Assisting the threads 34, 35 by cutting the slot 354 on the second thread 35 And the provision of the chip, so that the diameter r1 of the first screw 34 is equal to the diameter r2 of the second screw 35 or the diameter of the first screw 34 during the drilling and locking process. R1 is smaller than the diameter of the second screw 35, and the first screw 34 can be effectively utilized to assist in strengthening the drilling lock stress of the second screw 35, and the retaining rib 311 is inclined on the rod body 311. The taper is arranged to increase the torsion and tensile force during the drilling and locking process, so that the fastener 3 can have better stress tolerance and greatly increase the strength of the drill lock, and can still be used in the first The slots 354 on the upper and lower teeth 351, 352 are used for the cutting and cutting of the chips so that there is no excessive accumulation of chips to generate the locking resistance, so as to have a better locking fastening force and positioning effect.
歸納前述，本發明之緊固件，係於該桿體上同時具有該第一、第二螺牙之設置，同時另於該桿體之周緣於該任二第二螺牙間向外凸設有一止擋肋配合合設計，可於鎖合時，不但得以利用該第二螺牙上之開槽得以輔助該第一螺牙斬切物件及提供切削容置，以及該第一螺牙強化該第二螺牙之鑽鎖應力，同時再配合該止擋肋於該桿體上呈錐狀設置，以增加鑽鎖過程中之抗扭力與抗拉力，以達致鑽鎖後之防鬆退作用，以大幅提升鎖合定位與緊固力效果，故確實能達到本發明之目的。 In summary, the fastener of the present invention has the first and second threaded teeth disposed on the rod body, and a convex portion is disposed between the two second threaded teeth at the periphery of the rod body. The locking ribs are designed to cooperate to not only utilize the slots on the second thread to assist the first thread cutting object and provide cutting accommodation, and the first thread strengthens the first The drilling stress of the two threaded teeth is combined with the retaining rib on the rod body to increase the torsion and tensile force during the drilling and locking process, so as to achieve the anti-retraction effect after the drill lock In order to greatly improve the effect of the locking positioning and the fastening force, the object of the present invention can be achieved.
