In the process of continuously closing the door cover 4, the user applies downward pressure to the door cover 4 all the time, so that the door cover 4 starts to be closed gently by overcoming the elastic force of the pressure spring 32 and the friction force of the limiting damping block 111 on the sliding part 11 until the guide shaft 6 moves to the bottom of the arc section and is limited by the limiting damping block 111 at the position, at this time, the gravity of the door cover 4 is balanced with the elastic component force of the pressure spring 32 in the vertical direction and the static friction force of the limiting damping block 111, and the door cover 4 is in a static closed state.
Obviously, in the opening and closing process of the door cover 4, due to the double buffering and supporting functions of the limiting damping block 111 and the pressure spring 32, the door cover 4 can be opened and closed stably and safely, and the structural stability of the whole centrifuge is ensured.
