Abstract

Abstract. The use of locks has a history of thousands of years. Barbed-spring padlocks are the typical locks used in ancient China and can be divided into three main types, namely open-keyhole, hidden-keyhole, and blocked-keyhole padlocks. Since the mechanical structures of padlocks differ in terms of the opening process, they are reconfigurable mechanisms. With the combinations and changes of springs, keys, and keyholes, the padlocks have a variety of different unlocking methods which provide higher security. This work uses variable chains to analyze the structures of the blocked-keyhole padlocks. The representations of joints and chains are presented first. The structures and characteristics of representative barbed-spring padlocks are introduced. Six examples are provided to demonstrate the opening processes of blocked-keyhole padlocks. The result shows that it is a useful tool to realize the structural difference in the padlocks during operation.

中国传统锁孔锁的结构分析

摘要锁的使用已有数千年的历史。叉形弹簧锁是中国古代使用的典型锁，主要分为三种类型，即开锁孔锁、隐锁孔锁和锁孔锁。由于挂锁的机械结构在开启过程中有所不同，因此它们是可重构的机构。随着弹簧、钥匙和钥匙孔的组合和变化，挂锁有多种不同的解锁方法，提供了更高的安全性。本工作使用可变链来分析锁孔挂锁的结构。首先给出了关节和链的表示。介绍了具有代表性的倒钩弹簧挂锁的结构和特点。提供了六个例子来演示锁孔挂锁的打开过程。结果表明，它是一种在操作过程中实现挂锁结构差异的有用工具。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
