重力自动开合防尘盖的设计及应用

摘要

Using the vertical downward direction always gravity and leverage the basic principle, design a kind of gravity automatic switching device, can not only dust cover with lid automatic switching dust-proof function, and solved the problem easy to lose. The lid is a cheap and effective simple automatie open and closed agency, has certain practical value and wide prospect of market.%利用重力的方向总是竖直向下及杠杆作用的基本原理,设计了一种重力自动开合防尘盖装置,既能自动开合盖子具有防尘功能,又解决了盖子容易丢失的问题,是一种廉价而有效的简单自动张开和闭合机构,有一定的实用价值,市场前景广阔.
