Description
本創作為提供一種輪椅之鍊條迫緊結構，尤其是指一種快速調整且不易鬆脫的輪椅之鍊條迫緊結構。The present invention provides a chain tensioning structure for a wheelchair, and particularly refers to a chain tensioning structure of a wheelchair that is quickly adjusted and is not easy to loose.
按，請參閱第六圖所示，係為習用之輪椅惰輪結構，當使用者於使用時，係透過踏板之踩踏動作，由鍊條帶動輪具組，使輪椅得以前進，並透過習用之惰輪組400來調整鍊條之鬆緊度，藉此使用者可依據自身喜好或情況調整惰輪組，使輪椅使用上有更好的表現。Press, please refer to the figure 6 for the wheelchair idler structure. When the user is using it, the pedals are driven by the chain to drive the wheel set to advance the wheelchair and use the inertia. The wheel set 400 adjusts the tightness of the chain, so that the user can adjust the idler set according to his or her preference or situation, so that the wheelchair can be used better.
然上述習用之惰輪組400於使用時，為確實存在下列問題與缺失尚待改進：However, when the above-mentioned idler wheel set 400 is used, the following problems and defects are indeed to be improved:
一、透過一形成有溝槽之惰輪與鍊條接觸，於使用時會導致惰輪與鍊條相互摩擦，長期使用會有相互磨損之問題。1. The idler wheel formed by the groove is in contact with the chain, which causes the idler and the chain to rub against each other during use, and the long-term use may cause mutual wear.
二、習用惰輪係透過螺栓及螺帽夾持於一形成有孔洞之金屬片上，藉由放鬆螺栓及螺帽，使惰輪滑設於該孔洞內，並調整該惰輪高度以達成調整鍊條之鬆緊度，但長期使用下，螺栓與螺帽常因震動導致鬆脫，以至須常常調整惰輪高度及迫緊螺栓及螺帽。2. The conventional idler is clamped on a metal piece formed with a hole by bolts and nuts, and the idler wheel is slid into the hole by loosening the bolt and the nut, and the height of the idler is adjusted to achieve the adjustment of the chain. Tightness, but for long-term use, bolts and nuts are often loosened due to vibration, so the idler height must be adjusted and the bolts and nuts must be tightened.
是以，要如何解決上述習用之問題與缺 失，即為本創作之創作人與從事此行業之相關廠商所亟欲研究改善之方向所在者。Therefore, how to solve the above problems and problems Loss, which is the creator of the creation and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.
