[0018] The utility model will be further explained according to the drawings.

[0019] As Figures 1 to 5 shown, one side of the door plate 1 is connected with the door frame 2 through the hinge 3, the hinge 3 includes upper hinge 3-1, middle hinge 3-2 and lower hinge 3-3 from top to bottom, the other side of the door plate 1 is respectively provided with the lock body 4, the lock body 4 includes upper lock point 4-1, middle lock point 4-2 and lower lock point 4-3 from top to bottom, the upper lock point 4-1, the middle lock point 4-2 and the lower lock point 4-3 are connected through the linkage rod 4-4, the connecting place of the door plate 1 and the door frame 2 is provided with the expansion adhesive tape 5 and fireproof sealing strip 6.

[0020] In the embodiment, the distance between the upper hinge 3-1 and the lower hinge 3-3 and the edge of the door plate 1 is 200mm, and the distance between the middle hinge 3-2 and the upper hinge 3-1 is 500mm. The upper lock point 4-1 is located on the same horizontal line with the upper hinge 3-1, and the lower lock point 4-3 is located on the same horizontal line with the lower hinge 3-3.

[0021] One end of the expansion adhesive tape 5 abuts against the door plate 1, and the other end of the expansion adhesive tape 5 abuts against the door frame 2. The number of the expansion adhesive tape 5 is two, and the two expansion adhesive tapes 5 are oppositely arranged. As Figures 4 to 5 shown, one expansion adhesive tape is close to the inside of the door, and the other expansion adhesive tape is close to the outside of the door. The expansion adhesive tape mainly plays the role of realizing the weatherproof and airtight functions, and the double expansion adhesive tapes are better than the general ship door adhesive tape to realize the weatherproof and airtight functions.

[0022] The fireproof sealing strip 6 fills the gap between the two expansion adhesive tapes 5. The fireproof sealing strip is used to fill the gap between the double expansion adhesive tapes 5, and the fireproof sealing strip 6 is more heat-resistant and fire-resistant, which can better guarantee the fireproof integrity.

[0023] The hollow structure of the expansion rubber strip 5 can increase the softness of the rubber strip, better prevent rainwater from entering the door, and make the rubber strip expand and become larger when heated, fill the internal space of the door frame and the door panel, prevent smoke gas from passing through, and play a gas-tight function.

[0024] The door panel 1 is provided with a cavity, and the cavity is filled with fireproof rock wool 7, so that the whole door has a fireproof function. The lock tongue at the upper locking point 4-1, the middle locking point 4-2 and the lower locking point 4-3 of the lock body 4 is hidden in the door panel 1, so that the outside looks flat and not protruding, increasing the aesthetic appearance.

[0025] The door frame 2 and the peripheral wall 8 are provided with a compression rubber 9, and a bolt 10 passes through the door frame 2, the compression rubber 9 and the peripheral wall 8 in sequence to connect the door frame 2 and the peripheral wall 8, and is fastened by a nut 11. The compression rubber can play a gas-tight and waterproof role.

[0026] When the door is closed, the upper hinge 3-1, the middle hinge 3-2 and the lower hinge 3-3 are three fixed points and stress points of the hinge edge. The lock body 4 includes the upper locking point 4-1, the middle locking point 4-2, the lower locking point 4-3 and the linkage rod 4-4, and the single locking point is evenly embedded in the door panel 1, and is linked through the linkage rod 4-4. The three locking points are another three stress points of the door edge. When the door is closed, six fixed points are formed, and when the room is suddenly exploded and burned, because the ordinary fireproof door has two to three fixed points more on both sides, the impact force is evenly distributed upward, downward, left and right, and the pressure resistance is stronger, so that the probability of the door being blown open by the impact of the gas is greatly reduced. The conventional fireproof door generally has only one fixed point at the door lock, which is easily opened by the impact of the explosion pressure at the door lock point. At the same time, the door panel of the present application is thickened to 4MM, and the lock body and the hinge together form and strengthen the explosion-proof pressure resistance function. In the case of dealing with explosion or fire source leakage, the flame gas pressure can be easily controlled in a certain area, and the door panel will not be damaged due to the leakage of the fire source. Compared with the general fireproof door panel with a thickness of 1.2-1.5MM, the strength is not enough to deal with the impact of the explosion, and the door panel will be bent and opened by the impact wave.

[0027] As shown in Figure 6 , the lock body 4 is a CT-Z lock, which has multiple fixed lock tongue points, and the outside can be locked, and the inside can be quickly escaped by pushing the pressure rod when escaping. As shown in Figure 4As shown, each locking point is provided with a locking tongue 4-5, and a recessed lock catch 4-6 is provided at the door frame corresponding to the locking tongue 4-5, and locking is achieved by cooperation of the locking tongue 4-5 and the lock catch 4-6. In the present application, the multi-locking point fixing points of the CT-Z lock are cooperated with the hinge to meet the explosion-proof requirements.
