Figure 3As shown, the device body 1 includes four snap-in grooves 106, which are respectively opened on the inner walls of the top and bottom of the two ends of the fixed shell 101, and the top and bottom of the outer walls of the two ends of the sealing plate 103 are fixedly installed with plug-in boards 107. The outer wall of the plug-in board 107 is movably connected to the adjacent snap-in grooves 106. The connection between the snap-in grooves 106 and the plug-in boards 107 makes the connection between the sealing plate 103 and the fixed shell 101 tighter and more firmly.
[0027] In order to keep the heat insulation mechanism 2 stable inside the device body 1 so that it can stably play a heat insulation role, such as Figure 3-4 As shown, the vertical cross-sectional area of the inner wall of the fixed shell 101 is the same as the vertical cross-sectional area of the sealing plate 103, the vertical cross-sectional area of the insulation mechanism 2 is the same as the vertical cross-sectional area of the sealing plate 103, the cross-section of the reinforcing plate 204 is set to a wavy structure, the width of the reinforcing plate 204 is the same as the distance between the insulation plate 202 and the inner wall of the fixed shell 101, and the reinforcing plate 204 can fill and support the gaps between the insulation plate 202 and the fixed shell 101 and between the insulation plate 202 and the sealing plate 103, so that the insulation mechanism 2 can remain stable inside the device body 1.

Figure 2-4 As shown, the diameter size of the fixing hole 102 is the same as the diameter size of the connecting hole 104, the diameter size of the fixing hole 102 is the same as the diameter size of the mounting hole 203, the fixing hole 102, the connecting hole 104 and the mounting hole 203 are all arranged at equal intervals, the outer wall of the screw head of the connecting pin 105 and the outer wall surface of the fixed shell 101 are on the same plane, the diameter size of the screw part of the connecting pin 105 is the same as the diameter size of the fixing hole 102, and the connecting pin 105 penetrates the fixing hole 102 and the mounting hole 203 and is connected to the connected connecting hole 104, so that the device body 1 and the insulation mechanism 2 can be tightly connected.
[0029] The specific implementation method is as follows: when producing the fire door, one of the reinforcing plates 204 is fixed to the inner wall of the fixed shell 101, and then the insulation board 202 is fixed to the inside of the fixed shell 101, so that the two fixing seats 201 can be located at the two ends inside the fixed shell 101, and one of the reinforcing plates 204 can be located in the gap between the insulation board 202 and the fixed shell 101. At the same time, the mounting hole 203 can be aligned with the fixing hole 102, and then another reinforcing plate 204 is placed on the outer wall of the side of the heat insulation plate 202 away from the fixed shell 101, and then the sealing plate 103 is fixed to the open side of the fixed shell 101, so that the connecting hole 104 can be aligned with the adjacent mounting hole 203, so that the connecting pin 105 is used to penetrate the fixing hole 102 and the mounting hole 203, and connect with the adjacent connecting hole 104, so that the device body 1 and the heat insulation mechanism 2 can be assembled together, so that the fire door can be assembled.
