[0026] The technical solution includes a closed door body 3, a door groove 4, a horizontal rib 5, a vertical rib 6, a spring 13, a buffer plate 14, a buffer seat 15, a pressure sensor 16 and a display screen 17, which can greatly improve the use intensity of the closed door body 3. The pressure sensor 16 transmits the pressure data on the buffer seat 15 to the display screen 17, so that the personnel on one side of the closed door can timely understand the pressure on the other side of the closed door.

[0027] Embodiment 2:

[0028] On the basis of embodiment 1, the utility model is as follows Figures 1-3 As shown, it is disclosed that the top and bottom of both sides of the door frame 1 are fixedly connected with mounting plates 18, the surface of the mounting plates 18 is provided with mounting holes, and the edge of the surface of the closed door body 3 is fixedly connected with a sealing strip 19, the material of the sealing strip 19 is polyurethane, and the front and back of the closed door body 3 are fixedly connected with door handles, and the surface of the door handles is provided with an anti-rust coating.

[0029] Adopting the above technical solution, the main purpose is to install and fix the door frame 1 in the wall installation groove and increase the sealing performance between the surface of the airtight door body 3 and the inner cavity of the door frame 1. The installation bolts penetrate through the installation holes on the surface of the installation plate 18, and one end of the bolt is further screwed into the wall to complete the installation of the door frame 1. The sealing strip 19 is located at the edge of the surface of the airtight door body 3. After closing the airtight door body 3, the sealing strip 19 is clamped between the airtight door body 3 and the door frame 1, which can greatly improve the sealing performance between the airtight door body 3 and the door frame 1.

[0030] Embodiment 3:

[0031] Based on Embodiment 2, the present utility model is as shown in Figure 1 、 Figure 2 and Figure 5 It is disclosed that limiting rods are fixedly connected to both the top and bottom of the back surface of the buffer seat 15.
