Description

防鬆螺絲Locking screw

本新型是有關於一種螺絲結構，特別是一種有效提升鎖合穩固性及鎖合效果的防鬆螺絲。The utility model relates to a screw structure, in particular to a locking screw which effectively improves the locking stability and the locking effect.

參閱圖1所示，習知自攻螺絲1包含有一桿體11，一設於該桿體11一端之螺頭12，一相反於該螺頭12之鎖合部13，以及複數呈間隔設置於該桿體11之螺牙14，且該等螺牙14成型深度較深，亦即該等螺牙14之頂點與該桿體11間的距離較大，以使該等螺牙14具有足夠強度旋切物件並容納所產生的切屑；故進行鎖合作業時，藉由該鎖合部13抵壓於一物件之表面上（圖中未示），並於該螺頭12施予一旋轉扭力，使得該鎖合部13受該旋轉扭力帶動而鑽攻該物件，待該鎖合部13旋入該物件後，該等螺牙14接續該鎖合部13切削該物件，藉以連動該桿體11隨著該鎖合部13的鑽切及該等螺牙14的切削而逐漸進入該物件內，因此，該自攻螺絲1藉由該等螺牙14的設計，即可自行於該物件內鑽攻螺紋，故不需於該物件進行預先穿孔作業，進而減少鎖合作業所耗費的時間。Referring to FIG. 1 , the conventional self-tapping screw 1 includes a rod body 11 , a screw head 12 disposed at one end of the rod body 11 , a locking portion 13 opposite to the screw head 12 , and a plurality of spacers disposed at intervals The thread of the rod 11 is 14 and the threads 14 are deeper in depth, that is, the distance between the apex of the thread 14 and the rod 11 is large, so that the thread 14 has sufficient strength. Rotating the object and accommodating the generated chips; when engaging in the lock cooperation, the locking portion 13 is pressed against the surface of an object (not shown), and a rotating torque is applied to the screw 12 The locking portion 13 is driven by the rotating torsion to drill the object. After the locking portion 13 is screwed into the object, the threaded teeth 14 are connected to the locking portion 13 to cut the object, thereby interlocking the rod. 11 as the locking portion 13 is drilled and the cutting of the thread 14 gradually enters the object, so the self-tapping screw 1 can be self-contained in the object by the design of the screw 14 Drilling and tapping the thread, it is not necessary to perform pre-punching work on the object, thereby reducing the time spent on the lock cooperation industry.

然，實際使用後發現，該自攻螺絲1主要係利用該等螺牙14間呈間隔設置，亦即該等螺牙14非密集設於該桿體11上，藉以減少鎖合時與該物件的接觸面積，以使該自攻螺絲1於旋鎖入該物件時，不致與該物件間產生過大的鎖合阻力，亦或造成鎖合速度降低等情事產生，惟，該等螺牙14的設置數量過少，致使該等螺牙14與該物件的咬合面積過小，當該自攻螺絲1受外力拉扯或震動時，極容易造成該自攻螺絲1產生鬆動、搖晃或脫落的情況，進而導致該自攻螺絲1鎖合效果不彰，更甚者，當該自攻螺絲1用於鎖合厚度較小之物件時，其僅能仰賴更少數的螺牙14與該物件鎖接咬合，導致該等螺牙14與該物件間的咬合面積更加減少，更容易導致該自攻螺絲1鬆動、搖晃，甚至是脫落等情事產生，進而造成使用安全性不佳。However, it has been found that the self-tapping screws 1 are mainly disposed at intervals between the 14 screws, that is, the screws 14 are not densely disposed on the rod body 11 to reduce the locking and the object. The contact area is such that when the self-tapping screw 1 is screwed into the object, excessive locking resistance between the object is not caused, or the locking speed is lowered, etc., but the thread 14 is If the number of the screws is too small, the occlusal area of the screw 14 and the object is too small. When the self-tapping screw 1 is pulled or vibrated by external force, the self-tapping screw 1 may easily become loose, shake or fall off, thereby causing the self-tapping screw 1 to be loosened or detached. The self-tapping screw 1 has a poor locking effect. What is more, when the self-tapping screw 1 is used to lock a small-thickness object, it can only rely on a smaller number of threaded teeth 14 to engage with the object, resulting in The occlusal area between the thread 14 and the object is further reduced, which is more likely to cause the self-tapping screw 1 to loosen, shake, or even fall off, thereby causing poor safety in use.

再者，該等螺牙14因成型深度較深且呈間距設置，而無法與一般螺帽配合鎖接，若該自攻螺絲1因鎖合不佳而產生鬆動，亦或於鎖合過程中受外力影響而產生歪斜，導致該自攻螺絲1未鎖固於正確位置，其無法透過與螺帽鎖接而提升鎖合穩固性，若是為了配合該等螺牙14而特製鎖接用的螺帽，更可能造成生產成本提高，不符經濟效益，實有待改善。Furthermore, the threaded teeth 14 are deep and spaced apart from each other, and cannot be locked with the general nut. If the self-tapping screw 1 is loose due to poor locking, or during the locking process, The self-tapping screw 1 is not locked in the correct position due to the influence of the external force, and the bolt cannot be locked with the nut to improve the locking stability. If the screw is used for the screw 14 The cap is more likely to cause an increase in production costs, which is inconsistent with economic benefits and needs to be improved.

因此，本新型之目的，是在提供一種防鬆螺絲，其可針對厚度較小物件進行鎖合，同時與螺帽鎖接配合，進而有效提升鎖合穩固性及鎖合效果。Therefore, the purpose of the present invention is to provide a anti-loosening screw which can be locked for a small-thickness object and simultaneously engaged with the nut to effectively improve the locking stability and the locking effect.
