The study travel inherits and develops the education concept and the humanistic spirit of the traditional tourism of reading ten thousand books and moving ten thousand miles in China, and becomes a new content and a new mode of quality education.
In the study and travel process of children, most of the children need to live and study in the base. Elevators are important devices in bases and play an irreplaceable role in the research and travel of children. However, the danger coefficient of a child taking an elevator is far larger than that of an adult, on one hand, because the self-protection consciousness of the child is weak, when an elevator accident happens, the child does not understand how to take emergency measures. On the other hand, children are curious about all fresh things, and people often like to jump when taking the elevator, or press a button in the elevator at will, so that the accident probability of the elevator is increased. Therefore, china with publication number CN106219353B discloses "a child safety elevator", which includes a car and a safety seat disposed inside the car, wherein the safety seat is in a shell shape, an opening is disposed on a side surface of the safety seat, the safety seat is disposed on a floor of the car, an elastic member is disposed between the safety seat and the floor of the car, and the safety seat can rotate 360 degrees.
