[0002] In the prior art, there are many experiments or production processes in laboratories or production workshops that need to be operated in an anhydrous and oxygen-free environment. For example, some hydrides are very easy to oxidize and burn when encountering oxygen. Therefore, they are usually unpacked and loaded in a glove box in an anhydrous and oxygen-free environment before entering the next process, such as sending to a tubular furnace for sintering. At the same time, the sintering furnace also needs to be filled with a certain pressure (for example, 0.22MPa) of gas (or mixed gas, such as argon and hydrogen) during the sintering process. This requires a device that can be loaded from the glove box, sent to the next production process (tubular sintering furnace) with air pressure through a transfer cabin, and perform a partition operation. Due to the large size of the transfer cabin, a through section with a diameter of about 300mm is required. If a ball valve is used, its size is large and not very practical.

[0037] The atmospheric pressure cabin 1 and the pressure cabin 7 are adjacent to each other and separated by a bulkhead 5, and the two together constitute a transfer cabin.
[0038] The cross-sections of the atmospheric pressure cabin 1 and the pressure cabin 7 are rectangular (thin-walled cylindrical). The inlet end of the atmospheric pressure cabin 1 (i.e., the left end, see Figure 2 The pressure chamber 7 is rectangular (its periphery is a connecting flange), and the outlet end of the pressure chamber 7 is provided with a circular outlet (and is equipped with a circular flange with a sealing ring groove, see Figure 3 shown).
[0039] The pressure balance mechanism is composed of an air pipe 4 and a pressure balance valve 6. One end of the air pipe 4 is connected to the normal pressure cabin 1, and the other end is connected to the pressure balance valve 6. The pressure balance valve 6 is arranged on the upper part of the outer shell of the pressure cabin 7 and communicates with the inner cavity of the pressure cabin 7. Before the transfer operation, the pressure balance valve 6 can keep the internal pressures of the normal pressure cabin 1 and the pressure cabin 7 the same or close.
[0040] A barometer 8 is also installed on the upper part of the outer shell of the pressure cabin 7 . The interior of the barometer 8 is connected to the inner cavity of the pressure cabin 7 and is used to detect and display the inner cavity pressure of the pressure cabin 7 .
[0041] The bulkhead plate 5 is disposed between the atmospheric cabin 1 and the pressure cabin 7, and is provided with a door opening. The shape of the door opening may be rectangular, circular, or other shapes. In this embodiment, a shape with one side being rectangular and the other side being semicircular is adopted. A sealing ring groove for filling a sealing ring 18 is also provided around the door opening on the side of the bulkhead plate 5 facing the pressure cabin 7 (the sealing ring groove may also be provided on the side of the partition door 11 facing the atmospheric cabin 1).
[0042] The shape of the partition door 11 can be similar to the shape of the door opening, but slightly larger in size, so that its periphery can press the sealing ring on the bulkhead plate 5 to achieve a sealed separation of the two cabins. It can also be rectangular, but it is required that its periphery can press the sealing ring 18 on the bulkhead plate 5.
[0043] The hinge mechanism is composed of a fixed hinge seat 20, a movable hinge seat 27, a hinge seat connecting plate 23, a fixed hinge seat pin shaft 22, a movable hinge seat pin shaft 24 and a hinge limiting mechanism.
[0044] The fixed hinge seat 20, the movable hinge seat 27 and the hinge seat connecting plate 23 are in the shape of long plates, one end of the fixed hinge seat 20 and the movable hinge seat 27 are semicircular, and the other end is rectangular, and circular holes for inserting the fixed hinge seat pin 22 and the movable hinge seat pin 24 are respectively opened in the center of the semicircle; both ends of the hinge seat connecting plate 23 are semicircular, and circular holes for inserting the fixed hinge seat pin 22 and the movable hinge seat pin 24 are respectively opened in the center of the two semicircles.
[0045] The rectangular end of the fixed hinge seat 20 is arranged on the side of the bulkhead plate 5 on one side of the pressure cabin 7 (it can also be arranged on the rear side wall of the inner cavity of the pressure cabin 7), and the other end (i.e., the semicircular end) is hinged to one end of the hinge seat connecting plate 23 by the fixed hinge seat pin shaft 22; the rectangular end of the movable hinge seat 27 is arranged on the side of the partition door 11 facing the pressure cabin 7, and the other end (i.e., the semicircular end) is hinged to the other end of the hinge seat connecting plate 23 by the movable hinge seat pin shaft 24.
[0046] The hinge limiting mechanism is composed of a hinge limiting plate 26 , a fixed hinge seat tension spring hanging column 19 , a hinge limiting plate tension spring hanging column 25 and a tension spring 21 .
[0047] The fixed hinge seat tension spring hanging column 19 is arranged on the outer side of the fixed hinge seat 20 (ie, facing the rear side of the pressure chamber 7, see Fig.10 The hinge limiting plate 26 is in the shape of an elongated strip, which is arranged on the outer side of the hinge seat connecting plate 23, and its right end extends a small part, and the hinge limiting plate tension spring hanging column 25 is arranged on the extended part of the right end of the outer side of the hinge limiting plate 26; the two ends of the tension spring 21 are respectively hung on the fixed hinge seat tension spring hanging column 19 and the hinge limiting plate tension spring hanging column 25. The function of the hinge limiting mechanism is to ensure the order of the actions of each hinge seat during use, such as when opening the door, the movable hinge seat 27 acts first, and the fixed hinge seat 20 acts later; and when closing the door, the fixed hinge seat 20 acts first, and the movable hinge seat 27 acts later, so as to ensure that the partition door 11 and the bulkhead 5 are completely fitted (that is, to ensure complete sealing).
[0048] The door opening and closing power mechanism is composed of the door opening and closing power 3, the coupling 10 and the door opening and closing shaft 9. The door opening and closing power 3 (which can be a swing cylinder, a stepping motor or a reduction motor controlled by a photoelectric switch) is arranged on the upper part of the outer shell of the atmospheric pressure cabin 1, and its power output end is connected to the coupling 10 after passing through the inner cavity of the atmospheric pressure cabin 1. The upper end of the door opening and closing shaft 9 is connected to the coupling 10, and the lower end is connected to the sliding seat mechanism. A door opening and closing power sealing gasket 2 is arranged between the lower part of the door opening and closing power 3 and the upper part of the outer shell of the atmospheric pressure cabin 1 to ensure the sealing of the power output end of the door opening and closing power 3 when passing through the inner cavity of the atmospheric pressure cabin 1.
[0049] The slide mechanism is composed of a slide groove 14, a slide 13, a slide hinge pin 12, a swing arm 15, a swing arm seat 17 and a swing arm pin 16.
[0050] The chute 14 is in the shape of an elongated strip, with baffles disposed at both ends. The cross section of the cavity in the chute is in the shape of a "convex" character. The chute 14 is horizontally disposed in the middle of the side of the partition door 11 facing the atmospheric pressure cabin 1.
[0051] The cross section of the slide 13 is T-shaped, and its bottom (i.e., the "one" part of the "T" shape, that is, the "T" of the slide 13 is invertedly embedded in the "convex" cavity of the slide groove 14) is slidably embedded in the groove pit of the slide groove 14.
[0052] The swing arm 15 is in the shape of a long rod, with vertical holes at both ends thereof, which are respectively used to pass through the slide hinge pin 12 and the swing arm pin 16; the end used for forking the slide 13 is in the shape of a fork, which is used to fork the lower end of the "I" of the "T" shape of the slide 13 (that is, the upper end of the slide 13), and is swingably hinged on the upper end of the slide 13 by the slide hinge pin 12.
[0053] One end of the swing arm seat 17 is flat-bottomed, and the other end is forked, which is used to fork the non-forked end of the swing arm 15; the flat-bottomed end of the swing arm seat 17 is arranged on the inner cavity side wall of the atmospheric pressure cabin 1 (i.e., the rear side of the atmospheric pressure cabin 1, see Figure 2 or Figure 5 shown).
[0054] The other end of the swing arm 15 is swingably hinged on the protruding end (ie, fork end) of the swing arm seat 17 by the lower end of the switch door shaft 9, and the swing arm pin 16 penetrates the swing arm 15 and the switch door shaft 9 and connects the two into one.
[0055] Before use, the two ends of the transfer chamber (ie, the atmospheric pressure chamber 1 and the pressure chamber 7) are respectively connected to the glove box and the production process (ie, the tubular sintering furnace or other equipment).
[0056] When in use (at this time, the partition door 11 is in a closed state, see Figure 5 As shown), first load the items to be transferred in the glove box, then adjust the pressure in the atmospheric pressure cabin 1 and the pressure cabin 7 to the same or close state through the pressure balance valve 6 and the air pipe 4, then start the door opening and closing power 3, the power output end of the door opening and closing power 3 transmits the power to the coupling 10, and then to the door opening and closing shaft 9, then the door opening and closing shaft 9 brings the swing arm 15 to swing in the counterclockwise direction, and brings the slide 13 to move upward in the groove pit of the slide groove 14 (i.e.: the rear side direction of the atmospheric pressure cabin 1 and the pressure cabin 7), and then pushes the partition door 11 to swing in the counterclockwise direction around the fixed hinge pin 22 and the movable hinge pin 24. This swing, due to the restriction of the hinge limiting mechanism, makes the partition door 11 swing around the movable hinge pin 24 first, and then swing around the fixed hinge pin 22 when it swings to a certain position, and finally forms a state in which the swing arm 15 and the partition door 11 are parallel to the rear side of the atmospheric pressure cabin 1 and the pressure cabin 7 (see Figure 6As shown), the door opening and closing power 3 stops immediately, and the partition door 11 is fully opened, and the object transfer operation can be carried out. After the object transfer is completed, the door opening and closing power 3 is started to act in the opposite direction, which is opposite to the above-mentioned door opening action. When the door closing action is completed, the partition door 11 is completely attached to the bulkhead plate 5 and compresses the sealing ring 18 filled thereon, so that the sealing between the atmospheric pressure cabin 1 and the pressure cabin 7 can be ensured. At this point, the pressure cabin 7 can be pressurized again and subsequent operations can be carried out.
[0057] The transfer cabin partition door assembly of the present invention is suitable for transferring articles in spaces with different air pressures or different gas environments in laboratory equipment or special production workshops.
