Background

Earthquake is a natural disaster seriously harming life and property of people, China is one of the most serious countries in the world suffering from earthquake disasters, and particularly Wenchuan and Yushu in the last few years cause huge losses to life and property of people. Earthquake rescue experts point out that 72 hours after an earthquake occurs is internationally accepted as gold rescue time. Therefore, the first important after the earthquake occurs is to rescue the lives of people trapped by the earthquake. However, people cannot escape or avoid safely in a short time when an earthquake occurs because of the absence of a safe and effective refuge and life-saving device. Therefore, people are often buried by collapsed buildings when an earthquake occurs, so that life loss or injury is caused, especially in schools. Because the number of people in schools is too many, the trample event can be caused by emergency escape, and therefore, an adjustable earthquake safety desk needs to be designed to protect students, and loss is reduced.
