[0049] The working principle of a warehouse safety fire door based on Example 1 is:

[0050] The door frame 1 is fixed to the installation and fixing place provided on the wall, and then the door leaf 2 to be installed is moved to the installation opening 3 on the inner side of the door frame 1. At the same time, the right-angle plate 9 is pulled downward by hand to drive the clamping column 6 to move downward to the inner side of the rotating rod 5. At the same time, the return spring 10 is squeezed by force, and the conical notch 7 at the lower end of the rotating rod 5 is synchronously connected with the conical clamping block 22, so that the upper half of the conical clamping block 22 is located at the opening of the conical notch 7;

[0051] As the door leaf 2 is lowered, the rotating rod 5 is driven downward by the weight of the door leaf 2, and at the same time, the outer inclined surface of the conical clamping block 22 causes it to move relatively to the inner side of the conical notch 7.

[0052] At this time, the rotating rod 5 is in a vertical position, and then the right-angle plate 9 is loosened. The reset spring 10 rebounds without force and pushes the clamping column 6 to move upward, so that the clamping column 6 is stuck in the inner side of the reserved opening 4, and the door leaf 2 can be quickly installed and used. When it needs to be quickly disassembled, just pull the right-angle plate 9 again, and the clamping column 6 will be disengaged from the inner side of the reserved opening 4, so that the door leaf 2 can be quickly removed. There is no need to disassemble the entire fire door, and replacement can be easier and simpler.

[0053] The utility model provides a fire door for warehouse safety through improvement. When the fire door is worn out after long-term use and needs to be replaced, the door leaf 2 can be quickly disassembled and replaced by pulling the right-angle plate 9 to drive the clamping column 6 to disengage and insert it into the inner side of the reserved opening 4. During installation, the conical notch 7 and the conical clamping block 22 can be aligned, and the conical clamping block 22 can be driven to move to the inner side of the conical notch 7 by the gravity of the door leaf 2 itself, and the right-angle plate 9 can be loosened to allow the clamping column 6 to be re-inserted into the inner side of the reserved opening 4, so that quick installation and use can be achieved, and replacement can be more convenient and simple without the need for additional operation.
