[0035] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0036] like Figure 1-Figure 7As shown, a modular oxygen chamber of this embodiment includes a plurality of assembly plates 10 and a plurality of fasteners 20. The plurality of fasteners 20 are used to detachably connect adjacent assembly plates 10 to assemble into an oxygen chamber.

[0037] The assembly plate 10 includes a skin 15, a support frame 11 and a plurality of strips 12, wherein the strips 12 are fixed to the support frame 11 at the corner of the oxygen chamber, the skin 15 is used to close the support frame 11, the strips 12 have a plurality of first connection holes 12a, and the support frame 11 has a second connection hole 11a opposite to the first connection hole 12a. The support frame 11 is used to provide support to facilitate the connection of the fastener 20.

[0038] The fasteners 20 are fastened to the two assembly plates 10 at the corners of the oxygen chamber, and are fastened and matched with the corresponding first connection holes 12a and the second connection holes 11a, so as to realize the splicing of the assembly plates 10 at the corners of the oxygen chamber.

[0039] By fixing the strip 12 to the area of ​​the support frame 11 at the corner of the oxygen chamber, the support frame 11 is structurally reinforced. The first connection hole 12a of the strip 12 and the second connection hole 11a of the assembly plate 10 are fastened together with the fastener 20, increasing the total depth of the fastened holes. Therefore, under the relatively thin and light structure of the support frame 11, the connection strength requirements of the pressure environment can still be met, thereby achieving the purpose of reducing the weight of the assembly plate 10, while facilitating assembly and reducing material costs.

[0040] Among them, some of the assembled plate bodies 10 are arranged on the side walls of the oxygen chamber as side wall plates, some are arranged on the top of the oxygen chamber as top wall plates, and some are arranged on the bottom of the oxygen chamber as bottom wall plates. The corners of the oxygen chamber include the area where the side wall plate is connected to the top wall plate, the area where the side wall plate is connected to the bottom wall plate, and the area where two vertically arranged side wall plates are connected.

[0041] It is understandable that the fastener 20 can also be fastened to the two assembly plates 10 at the non-corner portions of the oxygen chamber, for example, Figure 5 Two or more assembly plates 10 are arranged in a row and then fastened by fasteners 20 to form a side wall of one side of the oxygen cabin.

[0042] There is no limit to the number of side wall plates, top wall plates, and bottom wall plates. In some embodiments, the number of top wall plates and bottom wall plates is one each, and the number of side wall plates is six.

[0043] Please refer to Figure 3-Figure 4In some embodiments, the plurality of first connection holes 12a on the strip 12 are arranged in two rows along its length direction, and the first connection holes 12a in each row are staggered in the width direction of the strip 12. Thus, each fastener 20 is also arranged in two rows, which increases the width of the connection and improves the sealing performance of the connection in a pressure environment.

[0044] In some embodiments, the strip 12 includes a connecting strip 121 and connecting pieces 122 connected at intervals on both sides of the connecting strip 121, the connecting pieces 122 on both sides are staggered in the width direction of the strip 12, and the first connecting holes 12a are arranged one by one on the connecting pieces 122. In this way, the weight of the strip 12 is further reduced, and after the strip 12 is fixed to the side wall plate, the weight of the side wall plate and the strip 12 as a whole can be reduced.

[0045] Please refer to Figure 2-Figure 4 In some embodiments, the assembled panel body 10 includes a main frame 13 and a rib plate 14, wherein the rib plate 14 is fixed inside the main frame 13 to form a support frame 11, and the skin 15 is wrapped around the outside of the support frame 11 and the strip 12, wherein the material density of the skin 15 is lower than the material density of the main frame 13.

[0046] It can be understood that the material density of the skin 15 is lower than the material density of the main frame 13, which further reduces the weight of the assembled panel 10, and the skin 15 is wrapped on the support frame 11 and thus supported by the support frame 11. Therefore, the above-mentioned low-density skin 15 can also meet the use requirements of pressure environment.

[0047] In some embodiments, the rib plate 14 includes a plurality of transverse plates 141 extending transversely and a vertical plate 142 extending vertically, the transverse plates 141, the vertical plates 142 and the main frame 13 form a plurality of hollow areas 14a, and the skin 15 is wrapped around the surface of the support frame 11 and closes the hollow areas 14a.

[0048] It is understandable that the hollow structure can reduce the weight of the rib plate 14 and the main frame 13, and then the hollow area 14a is closed by the lightweight skin 15, so as to reduce the overall weight.

[0049] The two ends of the vertical plate 142 are welded to the main frame 13 , one end of the horizontal plate 141 is welded to the vertical plate 142 , and the other end is welded to the vertical plate 142 or the main frame 13 .

[0050] In some embodiments, the skin 15 includes an outer skin layer and an inner skin layer that are connected to each other, the outer skin layer is a planar layer, and the inner skin layer is wrapped around the surface of the support frame 11 to form a groove 15a in the hollow area 14a.

[0051] The groove 15a facilitates the fastener 20 to achieve fastening connection. Specifically, when assembling two side wall panels, the fastener 20 is passed through the skin 15 and main frame 13 of one side wall panel, the skin 15 and main frame 13 of the other side wall panel from the position of the groove 15a, and then locked to achieve detachable assembly. The fastener 20 here can be a stud bolt and a nut. When assembling the side wall panel and the bottom wall panel, the fastener 20 is passed through the skin 15 and main frame 13 from the position of the groove 15a of the bottom wall panel, and then through the sticker 12 and the skin 15 and main frame 13 of the side wall panel. At this time, it is not necessary to penetrate the main frame 13 and skin 15 on the other side of the side wall panel.

[0052] It is understandable that the skin 15 is not limited. In some embodiments, the skin 15 includes a fiber part and a resin part. The fiber part has a gap inside, and the resin part is coated on the fiber part and filled in the gap. Specifically, the support frame 11 is wrapped with fiber (glass fiber, basalt fiber, chopped fiber, fiber felt cloth) resin and sealed by RTM (resin transfer membrane) and hand lay-up process, so that the surface has sealing performance.

[0053] In some embodiments, the main frame 13 is surrounded by a plurality of hollow tubes to reduce its weight.

[0054] In some embodiments, a plurality of the second connection holes 11a are arranged in two rows along the length direction of the tube body, and the second connection holes 11a in each row are staggered in the width direction of the tube body. By arranging the second connection holes 11a in two rows along the length direction of the tube body, and staggering the second connection holes 11a in each row in the width direction of the tube body, the connection sealing performance in a pressure environment is improved.

[0055] In some embodiments, a mounting hole is provided on part of the assembly plate body 10, and a flange is arranged in the mounting hole, which can be used as an internal and external connection step-up and step-down interface and can also be used as an entry and exit channel.

[0056] In some embodiments, the modular oxygen chamber includes a seal 30, and the seal 30 is disposed between adjacent assembly plates 10, so as to improve the sealing performance of the assembly plates 10 under pressure.

[0057] In some embodiments, the splicing process of the oxygen chamber is as follows: first, two assembling plates 10 are spliced ​​together to form the first side wall of the oxygen chamber, one assembling plate 10 is spliced ​​with the first side wall as the bottom wall of the oxygen chamber, two assembling plates 10 are assembled on opposite sides of the bottom wall as the second side wall and the third side wall, and the second side wall and the third side wall are spliced ​​with the first side wall. One assembling plate 10 is used as the top wall and spliced ​​with the three side walls. Then, the remaining two assembling side walls 10 are spliced ​​onto the above assembly in sequence to form the oxygen chamber.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
