Damping protection device of computer

The invention discloses a computer damping protection device which comprises a fixed box, two push plates which are symmetrical about the fixed box are slidably connected to an inner groove of the fixed box, an air bag is fixedly connected between the two push plates, an air outlet is fixedly connected to the air bag, a damping box is fixedly connected to the fixed box, and the damping box is fixedly connected to the fixed box. Four arc-shaped elastic supports distributed in a circumferential array mode are fixedly connected into the damping box, vent grooves are formed in the arc-shaped elastic supports, the arc-shaped elastic supports are elastically connected with the damping box through first springs, and a case is placed on the multiple arc-shaped elastic supports. In the process that the case is not vibrated in daily work, the first air cylinder is started to enable the two push plates to move relatively, then the push plates push out air in the air bags to cool the case, it is guaranteed that the case
