重力自动开合防尘盖的设计及应用

Design and Application of Gravity Automatic Switching Dust Cover

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,使其具有防尘功能,又能解决盖子容易丢失的问题,是一种廉价而有效的简单自动开合装置,可在工业控制领域的一定范围内应用,具有显著的经济效益,市场前景广阔。

This paper used the basic principle of gravity direction is always vertical downward and leverage function to design a kind of gravity automatic switching device,which can not only realized dust cover with lid automatic switching dust-proof function,but also can solve the lid easy to lose problem,it is a cheap and effective simple automatic open and closed institution,which can be used in industrial control field of a certain range,and has remarkable economic benefits and wide prospect of market.
