[0019] like Figure 1-3As shown, a fire door that is easy to install includes a fire door 1 and a connecting shaft 2. The fire door 1 can be rotatably arranged on the outer side wall of the connecting shaft 2. The connecting shaft 2 passes through one side of the fire door 1 and extends to both ends of the fire door 1. It also includes an inner frame 3 and an outer frame 4. The inner frame 3 is connected to both ends of the connecting shaft 2. The inner frame 3 is arranged in a C shape. The connecting shaft 2 is close to the opening side of the inner frame 3 and is used for supporting and opening and closing the fire door 1. The outer frame 4 is clamped on the outer side of the inner frame 3. The outer frame 4 is arranged in a reverse C shape. The outer frame 4 and the inner frame 3 are arranged to be buckled in opposite directions.
[0020] like Figure 4 and Figure 5 As shown, in order to make the fire door 1 quickly connected, a slot 5 is opened on the inner wall of the outer frame 4 away from the opening, and a cylinder 6 is installed on the upper and lower sides of the outer frame 4 close to the slot 5. The telescopic end of the cylinder 6 penetrates the outer frame 4 and is slidably arranged in the slot 5. A limiting hole 7 is opened on the bottom wall of the slot 5. The limiting hole 7 is coaxially arranged with the telescopic end of the cylinder 6. A clamping plate 8 is fixedly connected to the upper and lower end surfaces of the inner frame 3 close to the opening. A through hole 9 is opened in the clamping plate 8. The clamping plate 8 is rotatably clamped in the slot 5. The cylinder 6 The telescopic end passes through the through hole 9 and is inserted into the limiting hole 7. The side of the inner frame 3 connected to the card plate 8 is rotated and inserted into the card slot 5, so that the card plate 8 overlaps with the card slot 5, and one side of the inner frame 3 is fixed. The telescopic end of the cylinder 6 is driven to extend, so that the telescopic end of the cylinder 6 passes through the through hole 9 and is inserted into the limiting hole 7 to fix one side of the inner frame 3. A positioning hole 12 is opened on the side of the inner frame 3 close to the mounting plate 10, and the other side of the inner frame 3 is bolted and fixed to increase the stability of the connection of the inner frame 3.
[0021] A mounting plate 10 is provided on the upper part of the outer frame 4 away from the cylinder 6, and fixing holes 11 are opened at the corners of the mounting plate 10 for fixing the outer frame 4. An observation window 13 is installed on the side of the fire door 1 close to the positioning hole 12 to improve the observation ability of the fire door 1.
[0022] During specific use, the operator rotates one end of the inner frame 3 connected to the card plate 8 and engages it in the card slot 5, so that the card plate 8 overlaps with the card slot 5, drives the telescopic ends of the cylinders 6 on the upper and lower sides to extend, and makes the telescopic ends of the cylinders 6 pass through the through holes 9 and insert into the limit holes 7, thereby fixing one side of the inner frame 3. At the same time, the other side of the inner frame 3 is fixed to the wall by inserting bolts into the positioning holes 12, thereby increasing the stability of the fixation of the inner frame 3 on both sides.
