In this article, the manuscript of Codex Madrid I, Leonardo da Vinci's workshop drawings collection, is reviewed and the main mechanisms that appear in the aforesaid codex are analysed. It begins with a short reference to Leonardo da Vinci works and, subsequently, Leonardo's manuscripts and Codex Madrid I, in particular, are placed in their historical context. After analysing the historical scope of Codex Madrid I, a compilation of the 100 main drawings of the manuscript is made, composing nine Mechanisms Drawings Boxes. Each Mechanisms Drawings Box is a collage made up of 10 to 14 drawings of mechanical elements that appear in Codex Madrid I, with a brief description of each drawing. This compilation illustrates the wide range of mechanical elements and simple mechanisms of Codex Madrid I, forming, as a whole, a complete treatise on mechanisms, understanding mechanisms as basic elements of machines.

本文回顾了列奥纳多·达·芬奇 (Leonardo da Vinci) 工作室图纸集 Codex Madrid I 的手稿，并对上述手抄本中出现的主要机制进行了分析。它以对达芬奇作品的简短引用开始，随后将达芬奇的手稿和马德里手抄本 I 置于其历史背景中。在分析了 Codex Madrid I 的历史范围后，对手稿的 100 幅主要图纸进行了汇编，组成了九个机械图纸箱。每个 Mechanisms Drawings Box 都是一幅拼贴画，由 10 到 14 张出现在 Codex Madrid I 中的机械元素图纸组成，并附有对每张图纸的简要说明。本汇编说明了马德里法典 I 的广泛机械元素和简单机制，作为一个整体，
