自动防盗门开锁机构设计 摘要 随着社会物质则富的日益增长，安全防盗已成为社会热点问题自古以来锁就是把守门户的铁将军，是人们则富和安全的忠实守护神。现代社会，人们对防盗锁的要求越来越高，既要安全可靠，又要使用方便，这也是制锁者长期以来研制的主题。 随着电子、机电与信息技术的应用，防盗锁已进入电子时代，原有的弹子锁由于结构上的局限已难以满足当前社会管理和防盗要求，本设计在机械锁的基础上加以改进，用机械手控制机械锁，实现开锁的目的；机械手开锁机构锁保密好、使用方便，适用于多种用途，不仅增加了锁的种类，而且传统的制锁业能够应用电气、机电技术而获得新生。 关键词：机械手；开锁机构；机电技术 Design of automatic anti-theft door Unlocking mechanism Abstract With the growing social and material wealth, security has become as the hot social issues since accounted for since the lock is guarded portals of iron will The army is the people, rich and safe faithful patron saint. In modern society, people The anti-theft lock of the increasingly high demand, both safe and reliable, but also Easy to use, this is the lock have long development theme. With the Application of electronic, electrical and information technology, has entered the electricity anti-theft lock Age, the original lock because the structure of limitations has been difficult to full. The current social management and security requirements, this design based on mechanical lock. Improvement, manipulator control mechanical lock, to realize the unlocking purpose; the lock mechanism of manipulator lock good security, easy to use, suitable for a variety of purposes, not only increased the lock type, but the traditional The lock can be used electrical, mechanical and electrical technology was born.
