Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Referring to Figures 1-7, a fire escape door includes an outer door 1 and an inner door 2, the outer door 1 is provided with a first installation hole in the shape of a truncated pyramid, the inner door 2 is in the shape of a truncated pyramid, and the inner door 2 is a truncated pyramid. The door 2 is located in the first mounting hole on the outer door 1. The inner door 2 includes a first panel and a second panel. The junction of the first panel and the second panel is S-shaped. The small end of the inner door 2 A rotating shaft 7 is fixed on the board, and a turntable 3 is sleeved on the rotating shaft 7. The rotating shaft 7 and the turntable 3 are arranged eccentrically. 8 includes a paraffin block 81, a second spring 82 and a second pin 83, the paraffin block 81 is fixed in the second mounting hole, the inside of the paraffin block 81 is sleeved with a second spring 82 and a second pin 83, and the second pin 83 is Cylindrical, the second pin 83 is fixedly connected with the second spring 82, and the end of the second pin 83 away from the paraffin block 81 is inserted into the small end plate of the inner door 2, and the edge of the end face of the turntable 3 is fixed with a circular array of the first Two rings 9, the second ring 9 is connected with a rope 4, and the end of the rope 4 away from the second ring 9 is equipped with a positioning device 5, and the positioning device 5 is arranged on the four corners of the inner door 2 and the second on the inner door 2. Between the first panel and the second panel, the positioning device 5 includes a first spring 51, a baffle plate 52, a first ring 53, a stopper 54 and a first latch 55, and the side of the inner door 2 is plugged with a first A latch 55, the first latch 55 is fixedly sleeved with a baffle plate 52, the first latch 55 is sleeved with a first spring 51, the side of the first latch 55 is fixed with a first ring 53, and the side of the inner door 2 A U-shaped stopper 54 is fixed on the side, and the end of the rope 4 away from the second ring 9 is fixedly connected to the first ring 53.
