Carton with good heat preservation effect

The carton with the good heat preservation effect comprises a carton body and a foam heat preservation box, the foam heat preservation box is located in the center of an inner cavity of the carton body, two first penetrating holes are formed in the position, close to the center, of the bottom of the carton body, and threaded strip rods penetrate through inner cavities of the two first penetrating holes. The bottom ends of the two threaded strip rods are fixedly connected with supporting legs correspondingly, through the mutual matching relation of all the components, the foam heat preservation box is clamped through the adjacent clamping plates, and when equipment shakes, damping can be achieved, the situation that the foam heat preservation box shakes and collides with the side wall of an inner cavity of the carton body is prevented, and the service life of the equipment is prolonged. And the adjacent threaded strip rods are driven to rotate in the inner cavities of the first threaded holes and the second th
