Description

Technical Field

[0001] The present invention relates to the technical field of shelters, and more particularly to an assembled sealed aperture frame for a large-plate shelter. Background Art

[0002] Large-panel shelters typically feature movable openings in the decking to facilitate equipment installation and maintenance, as well as personnel entry and exit. These openings are constructed from specially shaped aluminum profiles with grooves for sealing strips. Existing large-panel shelter openings are formed by welding aluminum profiles in sections. This limited cross-section makes full welds difficult to achieve, leading to welding defects. Furthermore, aluminum profiles are significantly affected by welding heat, and full welds can easily deform the opening profile. The strength of aluminum profile welds is often lower than that of the parent material, and corners are susceptible to concentrated stress, which can lead to weld cracking. Summary of the Invention

[0003] In order to solve the problems of the existing segmented welding method of the cabin porthole profile being difficult to achieve sealing at the corners, large welding deformation, low porthole forming strength, and easy cracking of welds at the corners, the present invention innovatively provides a large-plate cabin assembled sealed porthole frame, which solves the problems of the large-plate cabin porthole being difficult to seal and processing deformation, and no longer uses the segmented welding method, without the influence of welding stress, thereby improving the overall frame strength, especially improving the strength of the porthole frame corners.

[0007] Furthermore, it also includes a sealing gasket, which is sleeved on the plug-in connector and clamped between two adjacent profiles.

[0008] Furthermore, the sealing gasket is a copper alloy sealing gasket.

[0009] Furthermore, the shape of the sealing gasket is the same as the longitudinal cross-sectional shape of the corner profile and the extension profile.

[0010] Furthermore, the longitudinal cross-sectional shapes of the positioning block and the connector are the same as the inner cavity shapes of the corner profile and the extension profile.

[0024] The assembled sealed port frame for a large-plate square cabin provided by the present invention will be explained and illustrated in detail below with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, the present embodiment specifically discloses a large-plate square cabin assembled sealed aperture skeleton (hereinafter referred to as "aperture skeleton"), including a corner profile 1, an extension profile 2, a positioning block 3 and a connector 4. The corner profile 1 and the extension profile 2 are connected to form a rectangular skeleton. The extension profile 2 is used to extend the horizontal and / or vertical length of the rectangular skeleton, that is, whether to install the extension profile 2 to extend the length can be selected according to the specific square cabin aperture size. If the length of the two corner profiles 1 can match the square cabin aperture size, the extension profile 2 does not need to be installed. If the sum of the lengths of the two corner profiles 1 is less than the square cabin aperture size, the extension profile 2 is installed between the corner profiles 1 to increase the length, and the number of installed extension profiles is set according to actual needs. The extension profile 2 is a linear structure.

[0026] The positioning block 3 and the connector 4 are used to connect two adjacent profiles (in the present invention, corner profiles and extended profiles are collectively referred to as profiles); for example, the connection between corner profiles 1 and corner profiles 1, the connection between corner profiles 1 and extended profiles 2, or the connection between extended profiles 2 and extended profiles 2, the positioning block 3 and the connector 4 make the connection between the two adjacent profiles detachable.

[0027] like Figure 2-4 As shown, both corner profile 1 and extension profile 2 are hollow structures. A positioning block 3 is inserted into the inner cavity of one of the two adjacent profiles. The positioning block 3 is detachably connected to the profile it is in. A connector 4 has two ends inserted into the inner cavities of the two adjacent profiles. The connector 4 is coaxially connected to the positioning block 3, and the end of the connector 4 away from the positioning block 3 is detachably connected to the profile it is in. The two ends of the connector are inserted into the inner cavities of the two adjacent profiles, aligning the two profiles coaxially. The positioning block and connector are coaxially connected, and the connection between the positioning block and connector seals the two profiles, minimizing the gap between the two profiles.

[0028] The corner profile 1 and the extended profile 2 are both integrally formed, using machining technology, which facilitates mass production and achieves high precision after forming. This avoids segmented welding, eliminates welding stress, and improves overall strength, especially at the corners.

[0029] The corner profile 1 and the expansion profile 2 are both hollow aluminum alloy profiles. The positioning block 3 and the connector 4 are both located inside the profiles, making the outside of the aperture frame smooth and facilitating alignment and sealing between adjacent profiles.

[0030] like Figure 2-4As shown, the assembled sealed port frame of the large panel cabin in this embodiment further includes a sealing gasket 5, which is sleeved on the plug-in connector 4 and clamped between two adjacent profiles. The sealing gasket 5 further ensures the sealing effect between the profiles and enhances the watertightness of the port frame.

[0031] In this embodiment, the sealing gasket 5 is a copper alloy sealing gasket. The copper alloy sealing gasket is relatively soft and easily deforms when squeezed, thereby ensuring excellent sealing performance. In addition, copper has excellent electrical conductivity and can effectively reduce electromagnetic leakage when used in electromagnetic shielding cabins.

[0032] like Figure 2 As shown, the shape of the sealing gasket 5 is the same as the longitudinal cross-section of the corner profile 1 and the expansion profile 2. The sealing gasket 5 is in full contact with the cross-section of the two adjacent profiles to avoid gaps and ensure good sealing.

[0033] The longitudinal cross-sections of the positioning block 3 and connector 4 mirror the inner cavities of the corner profile 1 and expansion profile 2. Their dimensions match those of the profile cavities, preventing radial movement within the profiles. They also serve as a positioning and connection mechanism, preventing misalignment between the connected profiles and ensuring the tightness of the shelter's aperture framework.

[0034] like Figure 2 As shown, the inner cavities of the corner profile 1 and the extension profile 2 are both L-shaped, and the corresponding positioning blocks 3 and connectors 4 are L-shaped. The plate structure of the inner cavity formed by the corner profile 1 and the extension profile 2 is L-shaped, including the outermost horizontal part of the rectangular skeleton and the vertical part inside. The corner profile 1 and the extension profile 2 also include a first groove and a second groove machined out. The notch directions of the first groove and the second groove are both toward the extension direction of the horizontal part. The first groove is located on the side of the vertical part away from the horizontal part, and the second groove is arranged on the vertical part. The groove depth of the first groove is the same as the horizontal length of the vertical part. The shapes of the corner profile 1 and the extension profile 2 meet the requirements of the aperture door body and door frame. As shown Figure 7 As shown, the shape of the sealing gasket 5 is exactly the same as the longitudinal cross-sectional shape of the corner profile 1 and the expansion profile 2, ensuring that both are in full contact with the two adjacent profiles.

[0035] The positioning block 3 and connector 4 are both detachably connected to the profile via set screws 6. The corner profile 1 and the extension profile 2 are provided with first threaded holes 7 that match the set screws 6. The set screws 6 securely connect the positioning block 3 to the profile in which it rests, and the end of the connector 4 not connected to the positioning block 3 is also securely connected to the profile in which it rests, also via set screws 6.

[0036] The positioning block 3 and the connector 4 are coaxially connected by a tensioning bolt 8. Figure 5 As shown, the positioning block 3 is provided with a stepped hole 9 along the axial direction. Figure 6As shown, the connector 4 is provided with a second threaded hole 10 coaxial with the stepped hole 9. The tensioning bolt 8 passes through the stepped hole 9 and is threadedly connected to the second threaded hole 10. Tensioning bolt mounting holes are provided on both sides of the corner profile 1. The tensioning bolts 8 securely connect the positioning block 3 and the connector 4. Turning the tensioning bolts 8 gradually shortens the distance between the two adjacent profiles until they abut against each other. The sealing gasket 5 is squeezed between the two profiles, sealing the joint between them and ensuring the tightness of the aperture frame.

[0037] Bolts are used to assemble the profiles without the influence of welding stress, which makes the overall strength of the orifice frame high and easy to disassemble and assemble.

[0038] In this embodiment, the rectangular aperture skeleton is formed by connecting four corner profiles 1 and two extension profiles 2. The two extension profiles 2 are respectively connected to the two horizontal sides of the rectangular aperture skeleton, and the extension profile 2 on each horizontal side is connected between the two corner profiles 1. In other embodiments, the number and setting position of the extension profiles 2 are selected according to the specific size of the cabin aperture. The number of tensioning bolts 8 is 2, which are respectively connected to the two sides of the L-shaped positioning block 3, making the fixation more stable. The number of first threaded holes 7 on each profile can also be multiple, and multiple set screws 6 are used for fixing, making the structure more stable.

[0039] The assembly method of the large-plate square cabin assembled sealed aperture frame of the present invention is as follows:

[0040] a) Determine the processing size and quantity of the extended profile 2 based on the size of the cabin opening and corner profile 1.

[0041] b) Fix the positioning block 3 and the connector 4 to the two profiles to be connected respectively with set screws 6.

[0042] c) The end of the connector 4 that is not connected to the profile is a free end, and the sealing gasket 5 is put on the free end of the connector 4.

[0043] d) Connect the two profiles and install the tensioning bolt 8 from the tensioning bolt assembly hole of the corner profile. By rotating the tensioning bolt 8, the distance between the positioning block and the connector is reduced, so that the two profiles are closer to each other, and finally the two profiles are in close contact with the sealing gasket 5. The sealing gasket 5 is squeezed between the two profiles to achieve a sealed connection between the two adjacent profiles.

[0044] e) Complete the docking of the remaining joints according to the above method, that is, complete the assembly of the assembled sealed opening frame of the large-plate square cabin.
