DETAILED DESCRIPTION
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment discloses an oxygen chamber door, including a door panel 12 and a door body 2. The door panel 12 is provided with an exit passage 121 for users to enter and exit the oxygen chamber. The door body 2 includes an inner panel 21 and a door body 22. The bottom of the inner panel 21 is connected to a slide rail 14. The inner panel 21 can move left and right. The movement of the inner panel 21 is driven by an electric cylinder (not shown in the figure). 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 5The inner plate 21 is installed with a bushing 24, which is inserted into the inner plate 21 and 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 is coaxially arranged with the bushing 25. The bushing 24 is installed with an insert rod 23, which passes through the bushing 1 24, and the axial ends of the insert rod 23 are inserted into the bushings 25 on both sides. The insert rod 23 and the bushing 1 24 have an interference fit, and the insert rod 23 and the bushing 2 25 have a clearance fit, so that the plate body 222 can move axially along the insert rod 23 to adjust its position. Both 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 22 moves, it drives the door body 22 to move synchronously.
[0028] Combine 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 main 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 provided along the outer periphery of the support frame 4 to form an annular groove. 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 main body 22 moves to the left to the left end, the sealing ring 3 is located on the side of the support frame 4 facing the door body main body 22. The sealing ring 3 is made of rubber. The sealing ring 3 is provided along the groove 41 and forms 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 Figure 2 、 Figure 3 As shown, the connecting port 1 32 is connected to a conduit 5, which is externally connected to an air pump. The conduit 5 is provided with a connecting portion 51, and both ends of the connecting portion 51 are respectively connected to the connecting ports 1 32 of the two sealing rings 3, so that the two connecting 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 and the plate body 222 close the outlet channel 121 toward the door panel 12 side. Since the rear sealing ring 3 is inflated at the same time, the two sealing rings 3 press the plate body 222 against each other after inflation, 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 panel 21 and causing derailment.
[0030] like Figure 3 、 Figure 4 As shown, the door panel 12 is mounted with a control valve 6. A second connection port 33 is provided at the right end of the sealing ring 3, near the door panel 12. This connection port 33 communicates with the inner cavity 31 and is connected to the air inlet of the control valve 6 via a first conduit 61. The control valve 6 has an air outlet. Specifically, the door panel 12 is also mounted with a valve body 7, which is provided with a first channel 71. One end of this channel 71 communicates with the first conduit 61, and the other end of this channel 71 is connected to the air inlet of the control valve 6 via a second conduit 62. The door panel 12 is also mounted with a second valve body 8, which is provided with a third channel 81. One end of this channel 81 connects to the air outlet of the control valve 6 via a third connection conduit 63, and the other end of this channel 81 communicates with the outside world. By controlling the opening of the control valve 6, the gas within the inner cavity 31 is discharged, allowing the sealing ring 3 to release the plate 222, thereby allowing the door body 2 to move.
[0031] Valve body 1 7 also has a second channel 72, which communicates with channel 1 71. Both axial sides of channel 2 72 are sealed by plug rods 73, which are threadedly connected to channel 2 72. By pulling out plug rods 73, the gas in inner cavity 31 can be manually discharged, thereby allowing door body 2 to be opened in the event of an emergency such as an electrical system failure, preventing accidents.
[0032] This embodiment also discloses an oxygen chamber, comprising a chamber 1, equipped with the aforementioned oxygen chamber door. A chamber 11 is provided within the chamber 1, comprising a door panel 12 and a bottom panel 13. A slide rail 14 is mounted on the bottom panel 13, and a support frame 4 is mounted on the bottom panel 13. Plug rods 73 are located on either side of a second channel 72, one located inside the chamber 11 and the other outside. This allows personnel inside and outside the chamber 11 to open the door 2 in an emergency.
[0033] This embodiment also discloses a method for using an oxygen chamber door, including the above-mentioned oxygen chamber and 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 depressurized 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 With control valve 6 in the closed position, the air pump pumps air into conduit 5 to inflate inner cavity 31. After the two sealing rings 3 are inflated, they press against plate 222, securing door body 2 and sealing one side of outlet passage 121, completing the door closing operation. While the door body 2 is secured, it can be moved forward and backward along the axial direction of rod 23 to fine-tune its position and prevent derailment.
[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.
[0037] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
