[0035] As shown in the appendix Figure 10As shown, on the side of the first fence 3 away from the first guide rail 4, a first connection block 36 is welded and fixed. The first connection block 36 is provided with a first air hole, and the first end of the first air hole is connected to a second air hole opened on the first fence 3. A first air nozzle is fixedly installed on the first inflatable sealing strip 25, and the first air nozzle is fixedly installed at one end of the second air hole away from the first air hole by screwing or interference fit, etc.

[0036] A first air charging pipe 7 is fixedly installed on the first connection block 36, and the first air charging pipe 7 is communicated with the first air hole. In this embodiment, the installation method of the first air charging pipe 7 can adopt methods such as screwing, interference fit, welding, etc.

[0037] As atta Figure 1 ched figure shows, the first air charging pipe 7 is installed with a first air discharging pipe 8 through a first air charging and discharging valve 6, and the first air charging pipe 7 is connected to an air charging source. The first air charging and discharging valve 6 is a manual three-way valve.

[0038] As atta Figure 1 ched figure shows, on the side of the outer door 5 away from the cylinder body 2, a pressure gauge 9, a first pressure balance valve 10 and a first handle 11 are also fixedly installed. Among them, the pressure gauge 9 is used to display the pressure inside the cylinder body 2, the first pressure balance valve 10 is used to adjust the pressure balance inside and outside the cylinder body 2, and the first handle 11 is used to pull the outer door 5.

[0039] As atta Figure 1 ched figure shows, a safety interlock 12 is also installed on the first fence 3, and the safety interlock 12 is used to lock the outer door 5 to prevent the outer door 5 from being opened when the cylinder body 2 is under pressure.

[0040] In this embodiment, the safety interlock 12 is a cylinder, and the cylinder is installed on the side of the first fence 3 away from the first guide rail 4 by bolts. The outer door 5 is provided with a limit hole or a limit groove. When the piston of the cylinder extends, it can be inserted into the limit hole or the limit groove to realize the locking of the outer door 5.

[0041] Of course, the cylinder can also be replaced with a structure such as an electromagnet that can achieve the same function.

[0042] The second end of the cylinder body 2 is located inside the oxygen chamber body 1, and an inner door 20 is installed. The installation method of the inner door 20 is the same as that of the outer door 5, and only a brief description is given below.

[0043] As atta Figure 2 ched and atta Figure 4 ched figures show, the second end of the cylinder body 2 is installed with a second fence 13 through a third bolt, and a second gasket 28 is installed between the second fence 13 and the cylinder body 2.

[0044] The side of the second fence 13 away from the cylinder body 2 is installed with a second guide rail 14 through a fourth bolt.

[0045] In this embodiment, the second fence 13 has the same structure as the first fence 3, and the second guide rail 14 has the same structure as the first guide rail 4.

[0046] That is, a U-shaped second chute 23 is provided on the side of the second guide rail 14 facing the second fence 13, and second buffer members 24 are fixedly installed at the ends of the second chute 23; second rollers are installed at the top and bottom of the inner door 20, and the second rollers are located in the second chute 23 and are in rolling cooperation with the second chute 23.

[0047] In this embodiment, the second buffer member 24 is installed at the end of the second chute 23 and can be a rubber pad or the like, which is used to prevent the inner door 20 from directly colliding with the end of the second guide rail 14.

[0048] A second pressure balance valve 21 and a second handle 22 are installed on the side of the inner door 20 away from the cylinder body 2.

[0049] A second through hole corresponding to the second end of the cylinder body 2 is provided on the second fence 13; a second annular groove 33 is provided on the second fence 13, and the second annular groove 33 surrounds the second through hole.

[0050] A second inflatable seal strip 27 is detachably installed in the second annular groove 33. When the inner door 20 is closed, the second inflatable seal strip 27 is inflated, and the second inflatable seal strip 27 expands and presses the inner door 20 to achieve sealing.

[0051] In this embodiment, the structure and installation method of the second inflatable seal strip 27 are the same as those of the first inflatable seal strip 25.

[0052] As shown in the appended Figure 2 and the appended Figure 9 As shown, a second connecting block 34 is fixedly installed on the side of the second fence 13 away from the second guide rail 14. A third air hole is provided on the second connecting block 34. The first end of the third air hole communicates with a fourth air hole opened on the second fence 13. A second air nozzle is fixedly installed on the second inflatable seal strip 27, and the second air nozzle is fixedly installed at one end of the fourth air hole away from the third air hole by screwing or interference fit or other means.

[0053] A second inflatable tube 15 fixedly connected to the third air hole is fixedly installed on the second connecting block 34. The end of the second inflatable tube 15 away from the second connecting block 34 is fixedly connected to the first end of a second inflation and deflation valve 16. The second end of the second inflation and deflation valve 16 is fixedly connected to the first end of a transition tube 18; the second end of the transition tube 18 is fixedly connected to the first end of a through-hull fitting 17, and the second end of the through-hull fitting 17 penetrates to the outside of the oxygen chamber hull 1 and is connected to an inflation gas source through a gas source tube.

[0054] The third end of the second inflation and deflation valve 16 is fixedly connected to a second exhaust tube 19.

[0055] The second charging and deflating valve 16 is also a manual three-way valve.

[0056] In this embodiment, the second pressure balance valve 21 and the first pressure balance valve 10 have the same structure. Taking the first pressure balance valve 10 as an example, its structure is as shown in the appendix Figure 11 and includes a connection hole opened on the outer door 5. The connection hole is threadedly connected to the first end of the connecting pipe 37 through an internal thread. The second end of the connecting pipe 37 is threadedly connected to the first end of the housing 39, and the first end of the housing 39 is communicated with the connecting pipe 37.

[0057] A through hole is provided at the second end of the housing 39. The axis of the through hole coincides with the axes of the housing 39, the connecting pipe 37, and the connection hole.

[0058] A valve stem 40 is slidably installed in the through hole. The first end of the valve stem 40 is located inside the housing 39 and is fixedly installed with a plug 45. The plug 45 can be inserted into the connecting pipe 37 and block the connecting pipe 37.

[0059] The plug 45 is in clearance fit with the housing 39.

[0060] A spring 44 is sleeved on the valve stem 40. The first end of the spring 44 abuts against the plug 45, and the second end of the spring 44 abuts against the inner wall of the second end of the housing 39.

[0061] The second end of the valve stem 40 is located outside the housing 39 and is hinged with a handle 43.

[0062] Specifically, two side plates 41 are fixedly installed at the first end of the handle 43. There is a gap between the two side plates 41, and the second end of the valve stem 40 is located between the two side plates 41; the limit bolt 42 passes through the middle parts of the two side plates 41 and the valve stem 40 and then installs a nut to realize the hinge connection between the handle 43 and the valve stem 40.

[0063] A plurality of ventilation holes 38 are opened on the side wall of the housing 39.

[0064] When it is necessary to adjust the air pressure in the cylinder body 2 to be the same as the atmospheric pressure, the handle 43 can be rotated so that the end of the side plate 41 abuts against the housing 39, and then continue to rotate until the axis of the handle 43 coincides with the axis of the valve stem 40. At this time, the plug 45 is pulled out from the connecting pipe 37 to realize the pressure relief of the cylinder body 2. Observe the pressure gauge 9 until the pressure in the cylinder body 2 is equal to the outside. Then restore the handle 43 to its original position.

[0065] Of course, the spring 44 in this embodiment can also be omitted. In this case, the operation for relieving the pressure of the cylinder body 2 is the same as that with the spring 44. However, when closing the first pressure balance valve 10, since there is no spring 44 pressing the plug 45 against the connecting pipe 37, it is necessary to press the valve stem 40 forcefully to tightly plug the plug 45 against the connecting pipe 37.

[0066] When adjusting the air pressure of the cylinder body 2 to be consistent with the pressure inside the oxygen chamber body 1, just adjust the second pressure balance valve 21.

[0067] The specific steps for transferring items from inside the chamber to outside the chamber are as follows: Step 1: The operator should check the state of the delivery outer door 5; at this time, the outer door 5 is in the normal open state, and the piston of the air cylinder should retract. Step 2: The personnel outside the chamber close the outer door 5 and close the first pressure balance valve 10. Step 3: The personnel outside the chamber adjust the first charging and discharging valve 6 on the outer side of the chamber and inflate the first inflatable sealing strip 25 through the inflation air source. Step 4: The operator inside the chamber opens the second pressure balance valve 21 on the inner door 20 to balance the pressure of the cylinder body 2 with the internal pressure of the oxygen chamber body 1. When the airflow sound of the second pressure balance valve 21 disappears, or when the pressure gauge 9 on the outer door 5 is consistent with the internal pressure of the chamber, it indicates that the pressure inside the cylinder body 2 has been balanced with the pressure inside the oxygen chamber body 1. Step 5: Open the second charging and discharging valve 16 on the inner side of the chamber to deflate the second inflatable sealing strip 27, and then the inner door 20 can be opened. Step 6: Place the items to be delivered out, close the inner door 20, and close the second pressure balance valve 21 properly. Adjust the second charging and discharging valve 16 to inflate the second inflatable sealing strip 27. Step 7: Notify the operator outside the chamber that the item-taking operation can be performed. Step 8: After receiving the report from inside the chamber, the operator outside the chamber first opens the first pressure balance valve 10 to balance the pressure inside the cylinder body 2 with the external environment pressure. When the pointer of the pressure gauge 9 returns to zero, or the airflow sound of the first pressure balance valve 10 has disappeared, or the latch of the safety interlock 12 has retracted, then the operator is permitted to adjust the first charging and discharging valve 6 to deflate the first inflatable sealing strip 25. Only after the deflation is completed can the outer door 5 be opened to take out the items.

[0068] The specific steps for transferring items from outside the chamber to inside the chamber are as follows: Step 1: The operator should check the state of the outer door 5. At this time, the outer door 5 is in the normal open state, and the piston of the air cylinder should retract. Step 2: Place the items to be delivered in. Step 3: Close the outer door 5 properly, close the first pressure balance valve 10, and adjust the first charging and discharging valve 6 to inflate the first inflatable sealing strip 25.

[0069] Step Four: The operator inside the cabin can perform the operation of taking the object. Step Five: After the operator inside the cabin receives the report from outside the cabin, perform the operation of taking the object. The operator inside the cabin opens the second pressure balance valve 21 on the inner door 20 to balance the pressure inside the cylinder body 2 with the pressure inside the oxygen cabin body 1. When the airflow sound of the second pressure balance valve 21 disappears, or when the pressure gauge 9 on the outer door 5 of the cylinder body is consistent with the internal pressure of the oxygen cabin body 1, it indicates that the pressure inside the cylinder body 2 has been balanced with the pressure inside the oxygen cabin body 1. Step Six: Adjust the second charging and discharging valve 16 to deflate the second inflatable sealing strip 27, and then the inner door 20 can be opened. Step Seven: After taking out the object, the inner door 20 and the second pressure balance valve 21 should be closed in time. Adjust the second charging and discharging valve 16 to inflate the second inflatable sealing strip 27. After inflation is completed, report to the personnel outside the cabin that the object delivery is completed. Step Eight: After the operator outside the cabin receives the report from inside the cabin, first open the first pressure balance valve 10 to balance the pressure of the cylinder body 2 with the external environment pressure. When the pointer of the pressure gauge 9 returns to zero, or the airflow sound of the first pressure balance valve 10 has disappeared, or the latch of the safety interlock 12 has retracted, it is only allowed to adjust the first charging and discharging valve 6 to deflate the first inflatable sealing strip 25. After deflation is completed, open the outer door 5 and keep the outer door 5 in an open state.

[0070] The above-mentioned inflation gas source, cylinder, etc. are all connected to the controller.

[0071] Obviously, the above-mentioned embodiments are only examples for clear illustration, rather than limitations on the implementation manners. For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
