Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door. Background technique [0002] For example, the hinge on the door frame described in Publication No. CN207879199U is connected with a fire door body. A fireproof sandbox is provided. The fireproof sandbox is provided with an opening on the bottom surface, and a blocked split ram is provided on the bottom of the fireproof sandbox. At the end of the telescopic rod, the hydraulic push rod is fixedly arranged on the outer walls of both sides of the top box through the connecting plate; the shortcoming of this invention is that the door cannot be opened and closed with the foot when the door is overheated. Contents of the invention [0003] The object of the present invention is to provide a fire door which can be opened and closed with a foot when the door is overheated. [0004] The purpose of the present invention is achieved through the following technical solut...
