Figure 5 The door body 22 is provided with a groove 221 , the right side and the lower end of the groove 221 pass through the door body 22 , and the inner plate 21 is inserted into the groove 221 . Figure 3 In the embodiment, the door body 22 includes plates 222 located at the front and rear sides, the inner plate 21 is at least partially located between the two plates 222, and the thickness of the inner plate 21 is less than the distance between the two plates 222, so that the door body 22 can move and adjust its position in the front and rear directions. Figure 3 , Figure 5, the inner plate 21 is installed with a bushing 24, which is inserted into the inner plate 21, and the bushing 24 is axially arranged in the front-to-back direction. The plate body 222 is installed with a bushing 25, which is inserted into the plate body 222, and the bushing 25 is coaxially arranged with the bushing 24. The bushing 24 is installed with a plug rod 23, which passes through the bushing 24, and the axial ends of the plug rod 23 are inserted into the bushings 25 on both sides. The plug rod 23 and the bushing 24 have an interference fit, and the plug rod 23 and the bushing 25 have a clearance fit, so that the plate body 222 can move axially along the plug rod 23 to adjust the position. The axial ends of the bushing 1 24 and the bushing 2 25 do not extend out of the inner plate 21 and the plate body 222. When the door body main body 22 moves, it drives the door body main body 22 to move synchronously.

[0028] Combination Figure 2 , 3 6. The oxygen cabin door also includes two support frames 4, which are arranged opposite to each other. The support frames 4 are rectangular frame structures, and the cross-section of the support frames 4 is as follows: Figure 3 As shown, the door body 22 can be moved to the left and inserted between the two support frames 4. The support frame 4 is provided with a groove 41, and the groove 41 is arranged along the outer circumference of the support frame 4 to form an annular groove, and the groove 41 passes through the support frame 4 and faces the side of the support frame 4. A sealing ring 3 is clamped in the groove 41, and the cross-section of the sealing ring 3 is square. After the door body 22 moves to the left end, the sealing ring 3 is located on the side of the support frame 4 facing the door body 22. The sealing ring 3 is made of rubber, and the sealing ring 3 is arranged along the groove 41 to form a ring shape. The sealing ring 3 is provided with an inner cavity 31 and a connecting port 32. The connecting port 32 is connected to the inner cavity 31, and the inner cavity 31 is annular. The connecting port 32 is located on the left side of the sealing ring 3, as shown in FIG. Figure 2 , Figure 3 As shown, the connection port 1 32 is connected to a catheter 5, and the catheter 5 is externally connected to an air pump. The catheter 5 is provided with a connecting portion 51, and both ends of the connecting portion 51 are respectively connected to the connection ports 1 32 of the two sealing rings 3, so that the two connection ports 1 32 are interconnected, so that the inner cavities 31 of the sealing rings 3 on both sides are inflated at the same time.

[0029] At the same time, after the plate body 222 moves to the left end, the sealing ring 3 is arranged along the circumference of the plate body 222. After the sealing ring 3 on the front side is inflated, it closes the outlet channel 121 toward the door panel 12 side together with the plate body 222. Since the sealing ring 3 on the rear side is inflated at the same time, the two sealing rings 3 are inflated and press the plate body 222 against each other, so that the position of the door body 2 remains fixed. Since the door body 22 can move and adjust its position in the front and rear directions, the front and rear sides of the plate body 222 can automatically adjust their front and rear positions during the process of being gradually inflated and pressed by the sealing ring 3, preventing the door body 2 from derailing from the slide rail 14 when subjected to the front and rear forces, thereby ensuring the safety and stability of the door body 2. Since the inner cavities 31 of the sealing rings 3 on both sides are inflated at the same time, the distance that the plate body 222 moves in the front and rear directions is reduced, so as to prevent the plate body 222 from being squeezed back and forth with the inner plate 21 and causing derailment.

[0030] like Figure 3 , Figure 4 As shown, the door panel 12 is equipped with a control valve 6, and the right end of the sealing ring 3 close to the door panel 12 is provided with a second connection port 33, which is connected to the inner cavity 31, and the second connection port 33 is connected to the air inlet of the control valve 6 through the first conduit 61, and the control valve 6 is provided with an air outlet.

The plug rods 73 on both sides of the axial direction of the second channel 72 are located in the cabin 11 and outside the cabin 11, so as to cope with emergency situations, so that people inside and outside the cabin 11 can open the door body 2.

[0033] This embodiment also discloses a method for using an oxygen chamber door, including the oxygen chamber and the oxygen chamber door. The specific steps of use are as follows:

[0034] ① When the inner cavities 31 of the sealing rings 3 on both sides are in the pressure relief state, the door body 2 moves to the left end and is inserted between the support frames 4 on both sides, so that the plate body 222 is located between the sealing rings 3 on both sides.

[0035] ② The control valve 6 is in the closed state, and the air pump is used to pump air into the conduit 5 to inflate the inner cavity 31. After the two sealing rings 3 are inflated, they press the plate 222 against each other to keep the position of the door body 2 fixed, and close one side of the outlet channel 121 to complete the door closing operation. During the fixing process, the door body 2 can move forward and backward along the axial direction of the insertion rod 23 to fine-tune the position to prevent the door body 2 from derailing.

[0036] ③ By opening the control valve 6, the gas in the inner cavity 31 is discharged, so that the door body 2 can move freely to open the outlet channel 121. Alternatively, by manually opening the plug rod 73, the gas in the inner cavity 31 can also be discharged to complete the door opening operation.
