Abstract

The invention relates to a plastic dustbin with heat-resisting and fireproofing functions. The plastic dustbin comprises a cylindrical plastic bin body with an upper opening and a plastic cover, wherein the plastic cover comprises a top wall and a cylindrical sleeve type side wall; at least one window is formed in the side wall; a groove is formed in the outer wall of the plastic bin body, a clamp ring is arranged in the groove, and a bulged part is formed in the side wall of the plastic cover and supported on the clamp ring, so that the plastic cover is kept in the use position; and when the temperature inside the plastic bin reaches to a set value, the clamp ring retracts and / or melts, so that the plastic cover slides downwards along the outer wall of the plastic bin body under the gravity action of the plastic cover, and a channel from the window to the upper opening of the plastic bin body is closed. According to the plastic dustbin, oxygen required by burning is prevented from entering the plastic bin body or remarkably reduced, so that spreading of naked light or smouldering fire is prevented, and the fireproofing safety of the dustbin is improved greatly.
