Abstract
Description
本發明係與螺栓有關，詳而言之，係指一種防鬆脫之螺栓。 The invention relates to bolts and, in particular, to a bolt that is resistant to loosening.
按，螺接結構係由螺絲與螺帽組成，將螺絲穿設待固定物後，復與螺帽螺接，以便將待固定物固定。當螺接結構係承受變動負荷或經常處於震動情況時，常會使螺絲與螺帽在不可預知的情況下鬆脫，造成不必要的困擾與損失，尤其是運用於高速運行之交通工具或機械設備，可能造成嚴重威脅著人類生命的安全，因此如何解決螺絲與螺帽間的鬆動脫落問題，已成為一個重要課題。 Pressing, the screwing structure is composed of a screw and a nut. After the screw is inserted into the object to be fixed, it is screwed with the nut to fix the object to be fixed. When the screw-on structure is subjected to a variable load or is often in a vibration condition, the screw and the nut are often loosened under unpredictable conditions, causing unnecessary troubles and losses, especially for vehicles or mechanical equipment that are used for high-speed operation. It may pose a serious threat to the safety of human life, so how to solve the problem of loosening between the screw and the nut has become an important issue.
為防止螺帽與螺絲發生鬆脫，習知一種方式防止鬆動之方式係將彈性墊圈設於螺帽與螺絲之間，當螺絲與螺帽螺接後，該螺帽擠壓迫緊彈性墊圈，使得彈性墊圈利用彈性撐抵於螺帽與待固定物之間，可防止螺帽與螺絲鬆脫。習知另一種方式則是將一彈性物件設於螺帽之螺孔中，並彈性頂持於螺絲之螺紋，以防止螺絲與螺帽鬆動。 In order to prevent the nut and the screw from loosening, a method for preventing the loosening is to place the elastic washer between the nut and the screw. When the screw is screwed to the nut, the nut is pressed to press the elastic washer. The elastic washer is elastically supported between the nut and the object to be fixed to prevent the nut and the screw from coming loose. Another conventional method is to place an elastic member in the screw hole of the nut and elastically hold the screw thread to prevent the screw and the nut from loosening.
習知螺帽與螺絲鬆脫之結構，係將彈性物體設於螺絲與螺帽之間，，並未見針對螺絲/螺栓本身之防鬆脫設計，基 於此一目的，發明人乃研發出本發明。 The structure of the nut and the loose screw is that the elastic body is disposed between the screw and the nut, and the anti-loose design for the screw/bolt itself is not seen.
