Description

Technical Field

[0001] The present invention relates to the field of magnetic shielding technology, and in particular to a magnetic shielding material panel installation node structure and an installation method. Background Art

[0002] With the rapid development of shielding technology, people are more and more urgent to explore extremely weak magnetic fields. The research on weak magnetic fields under magnetic shielding has broken through the original limit, and the requirements for the measurement environment close to "zero magnetism" are getting higher and higher. Miniaturized extremely weak magnetic fields can achieve a certain extremely weak magnetic space through the stacking of general magnetic shielding layers and active magnetic compensation technology. However, for the research on weak magnetic fields in large spaces, due to the limitations of materials, structures and installation processes, there is no mature and reliable installation design solution to ensure the overall high-index magnetic shielding performance.

[0003] For example, publication number "CN219060624U" discloses "a connection structure for an adjustable angle roof curtain wall", including a support, a connecting member and a keel, wherein the connecting member includes a connecting plate and a bearing member, which is detachably connected to the support through the connecting plate and rotatably connected to the keel through the bearing member. The bearing member can also slide in the keel, and a limiting body for limiting the movement of the keel is provided in the keel.

[0004] However, in actual applications, in the construction of large shell-type magnetic shielding spaces, this type of structure has poor shielding effect in extremely weak magnetic fields, and there will be magnetic leakage at the joints, which cannot achieve a high magnetic shielding effect. Summary of the invention

[0005] In view of the problems of poor magnetic shielding effect and magnetic leakage in the prior art mentioned in the background technology, the present invention provides a magnetic shielding material panel installation node structure, which can improve the quality of splicing and reduce magnetic leakage at the joints in the construction of large shell-type magnetic shielding spaces, thereby achieving a higher magnetic shielding effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions.

[0007] A magnetic shielding material panel installation node structure includes a base frame, a plurality of magnetic shielding components are arranged on the base frame, an installation gap is left between adjacent magnetic shielding components, a conductive layer cover plate and a magnetic shielding cover plate are connected between adjacent magnetic shielding components, and the conductive layer cover plate and the magnetic shielding cover plate cover the installation gap. The conductive layer cover plate and the magnetic shielding cover plate are respectively connected to the magnetic shielding components, and are bent according to the relative angles of the magnetic shielding components on the adjacent two sides, so that the conductive layer cover plate and the magnetic shielding cover plate can cover the gap between the two magnetic shielding components, thereby minimizing the influence of the external magnetic field on the interior, and the conductive layer cover plate is connected to the conductive layer panel, so that each magnetic shielding component can be turned on, and the magnetic shielding cover plate can ensure the integrity of the magnetic shielding effect and reduce the influence of leakage magnetic flux.

[0008] Preferably, the magnetic shielding assembly includes a rotating unit, the rotating unit is connected to the base frame, and the magnetic shielding assembly can rotate relative to the base frame. The rotating unit enables the magnetic shielding assembly to rotate around the base frame, thereby improving the flexibility and adaptability of the magnetic shielding assembly during installation, and the angle of the magnetic shielding assembly can be flexibly adjusted according to the construction conditions on site.

[0009] Preferably, the rotating unit includes a fixing portion connected to the base frame, the fixing portion is provided with an adjustment hole, the base frame is connected with a fixing piece, and the fixing piece passes through the adjustment hole to connect to the fixing portion. Through the connection between the adjustment hole and the fixing piece, the rotating unit can be displaced and adjusted relative to the base frame, so that the upper and lower positions of the magnetic shielding assembly can be changed. The flexible adjustability of the magnetic shielding assembly during installation is improved.

[0010] Preferably, the base frame and the fixing part are connected by a tooth meshing connection, so that the connection between the base frame and the fixing part is more secure, the vertical support capacity of the base frame to the fixing part can be improved, and the displacement tendency of the fixing cloth in the vertical direction of the base frame can be reduced.

[0011] Preferably, the magnetic shielding cover plate is arranged above the conductive layer cover plate, and the bending degree of the magnetic shielding cover plate and the conductive layer cover plate is the same as the relative angle of the adjacent connected magnetic shielding components. By setting the bending degree of the magnetic shielding cover plate and the conductive layer cover plate to be the same as the angle of the magnetic shielding component, it is possible to ensure that the magnetic shielding cover plate and the conductive layer cover plate are completely fitted with the magnetic screen wall component, thereby improving the docking during the installation process. This reduces magnetic leakage and improves the conductivity efficiency.

[0012] Preferably, the base frame is detachably connected with an adjustment vertical plate, and the adjustment vertical plate is movably connected with a lifting plate on one side close to the conductive layer cover plate, and the lifting plate can abut the bending line of the conductive layer cover plate at one end close to the conductive layer cover plate. By setting the adjustment vertical plate, it is possible to flexibly choose whether to install the adjustment vertical plate to adjust the angle of the conductive layer cover plate during the installation process. The flexibility of installation is improved. During use, the adjustment vertical plate is adjusted to a suitable height or an adjustment vertical plate of a suitable height is selected. The end of the adjustment vertical plate coincides with the bending line of the conductive layer cover plate at the ideal position. Thereby, the bending degree of the conductive layer cover plate can be corrected. After the correction is completed, the adjustment vertical plate can be removed to avoid increasing the overall load. The height of the adjustment vertical plate can be adjusted by the lifting plate, so as to adapt to magnetic shielding components at different angles. The connection relationship between the adjustment vertical plate and the base frame includes but is not limited to sliding connection, snap connection, bolt connection, and plug-in.

[0013] Preferably, the lifting plate is hinged with a plurality of movable positioning pages at one end close to the conductive layer cover plate, and each of the movable positioning pages can move independently, and the movable positioning page can rotate around the end of the lifting plate to abut the magnetic shielding component. The lifting plate is provided with movable positioning pages, and the movable positioning pages are provided in a plurality and are not integral, so each movable positioning page can move independently. Thereby, it is possible to fit with the magnetic shielding components on both sides in a dispersed manner. Whether the end height of the lifting plate is in an ideal position can be judged by whether the degree of combination is complete. If the height of the lifting plate is in an ideal state, the movable positioning page can completely fit the magnetic shielding component, otherwise further adjustment is required. This structure can improve the efficiency and accuracy in the process of calibrating the conductive layer cover plate.

[0014] The invention also discloses an installation method, comprising the following steps: S1. Assemble the magnetic shielding assembly and connect it to the base frame; S2. Adjust the relative positions and angles of adjacent magnetic shielding components on the base frame; S3, connecting the conductive layer cover plate to the adjacent magnetic shielding assembly; S4. Connect the magnetic shielding cover plate to the adjacent magnetic shielding assembly.

[0015] Preferably, in step S3, when the bending degree of the conductive layer cover plate does not match the angle of the adjacent magnetic shielding component, an adjustment vertical plate is connected to the base frame, and after the lifting plate is adjusted to a suitable position, the bending part of the conductive layer cover plate is abutted against the end of the lifting plate, and the conductive layer cover plate is pressed to both sides until it fits with the adjacent magnetic shielding component. When the angle of the conductive layer cover plate does not match, it is necessary to adjust the angle of the conductive layer cover plate, and since the bending line of the conductive layer cover plate is in a gap position, it is impossible to find a suitable fulcrum for angle adjustment. This method connects a detachable adjustment vertical plate to the base frame, thereby providing a standard fulcrum for the adjustment of the conductive layer cover plate, that is, the bending line of the conductive layer cover plate needs to abut against the end of the adjustment vertical plate. Both sides of the conductive layer cover plate need to completely fit the magnetic shielding component. The adjustment vertical plate can also provide a limit for the process of correcting the conductive layer cover plate to avoid excessive adjustment.

[0016] Preferably, the movable positioning page is abutted against the magnetic shielding components on both sides, and the adjustment vertical plate is installed, the lifting plate is adjusted until the movable positioning page fits the magnetic shielding components on both sides, the conductive layer cover plate is pressed to adjust to a given angle, the adjustment vertical plate is taken out, and the conductive layer cover plate is installed. Since the movable positioning page needs to abut against the magnetic shielding components on both sides, the width of the movable positioning page is greater than the gap between the magnetic shielding components on both sides. During the installation of the adjustment vertical plate, the movable positioning page needs to be placed on the magnetic shielding component at the same time. Whether the height of the adjustment vertical plate at this time is appropriate can be reversely deduced by whether the movable positioning page is completely in contact with the magnetic shielding component, so that the subsequent adjustment of the conductive layer cover plate can be facilitated. In the process of adjusting the conductive layer cover plate, the conductive layer cover plate fits the upper surface of the movable positioning page, and since the upper surface and the lower surface of the movable positioning page are parallel, the lower surface of the movable positioning page fits the magnetic shielding component. If the conductive layer cover plate is in contact with the upper surface of the movable positioning page, it means that the conductive layer cover plate can completely fit the magnetic shielding component.

[0017] The beneficial effects of the present invention are as follows: (1) It can improve the quality of joints and reduce magnetic leakage at joints in the construction of large shell-like magnetic shielding spaces, thus achieving a higher magnetic shielding effect; (2) It can improve the flexibility and adaptability of the magnetic shielding assembly during the installation process and improve the installation efficiency; (3) It can provide a standard correction fulcrum for the conductive layer cover plate with angle deviation, and provide a limit for the adjustment of the conductive layer cover plate to avoid excessive adjustment; (4) The accuracy of the conductive layer cover plate during adjustment can be improved, the adjustment effect of the conductive layer cover plate is more significant, and the judgment of the staff is improved.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment 1: like Figure 1As shown, a magnetic shielding material panel installation node structure includes a base frame 1, a plurality of magnetic shielding components 2 are arranged on the base frame 1, an installation gap is left between adjacent magnetic shielding components 2, a conductive layer cover plate 3 and a magnetic shielding cover plate 4 are connected between adjacent magnetic shielding components 2, and the conductive layer cover plate 3 and the magnetic shielding cover plate 4 cover the installation gap. The conductive layer cover plate 3 and the magnetic shielding cover plate 4 are respectively connected to the magnetic shielding components 2, and are bent according to the relative angles of the magnetic shielding components 2 on the adjacent two sides, so that the conductive layer cover plate 3 and the magnetic shielding cover plate 4 can cover the gap between the two magnetic shielding components 2, thereby minimizing the influence of the external magnetic field on the interior, and the conductive layer cover plate 3 is connected to the conductive layer panel 25, so that each magnetic shielding component 2 can be turned on, and the magnetic shielding cover plate 4 can ensure the integrity of the magnetic shielding effect and reduce the influence of leakage magnetic flux.

[0028] like Figure 2 , 3 As shown, the magnetic shielding assembly 2 includes a rotating unit 7, which is connected to the base frame 1, and the magnetic shielding assembly 2 can rotate relative to the base frame 1. The rotating unit 7 includes a fixing portion 71 connected to the base frame 1, and an adjustment hole 72 is provided on the fixing portion 71. The base frame 1 is connected to a fixing member 121, and the fixing member 121 passes through the adjustment hole 72 and is connected to the fixing portion 71. The base frame 1 and the fixing portion 71 are connected by a tooth meshing connection.

[0029] The magnetic shielding assembly 2 can be rotated around the base frame 1 by the rotating unit 7, so that the flexibility and adaptability of the magnetic shielding assembly 2 during the installation process can be improved, and the angle of the magnetic shielding assembly 2 can be flexibly adjusted according to the construction conditions on site. Through the connection between the adjustment hole 72 and the fixing part 121, the rotating unit 7 can be displaced and adjusted relative to the base frame 1, so that the upper and lower positions of the magnetic shielding assembly 2 can be changed. The flexibility and adjustability of the magnetic shielding assembly 2 during the installation process are improved. Through the tooth meshing connection between the two, the connection relationship between the base frame 1 and the fixing part 71 is made firmer, which can improve the vertical support capacity of the base frame 1 to the fixing part 71 and reduce the displacement tendency of the fixing cloth in the vertical direction of the base frame 1.

[0030] like Figure 1 , 2 As shown in Figure 3, the magnetic shielding cover plate 4 is arranged above the conductive layer cover plate 3, and the bending degree of the magnetic shielding cover plate 4 and the conductive layer cover plate 3 is the same as the relative angle of the adjacent connected magnetic shielding assembly 2. By setting the bending degree of the magnetic shielding cover plate 4 and the conductive layer cover plate 3 to be the same as the angle of the magnetic shielding assembly 2, it is possible to ensure that the magnetic shielding cover plate 4 and the conductive layer cover plate 3 are completely fitted with the magnetic screen wall assembly, and improve the docking during the installation process. This reduces magnetic leakage and improves the conductive efficiency.

[0031] like Figure 1 , 2 , 3, and 4, the assembly and working process of the magnetic shielding material panel installation node structure in this embodiment is as follows: In this embodiment, the base frame 1 includes an I-beam 11 and a support frame 12, wherein the support frame 12 in this embodiment is a "U"-shaped frame structure, the support frame 12 is installed above the I-beam 11, and the support frame 12 is connected to the magnetic shielding component 2. Further, in this embodiment, a track groove 111 is provided on the I-beam 11, wherein the groove shape inside the track groove 111 is a "convex" shape, and when connecting the I-beam 11 and the support frame 12 When installing, place the support frame 12 above the track groove 111, and place bolts inside the track groove 111. Due to the "convex" shape, the bolts placed inside the track groove 111 will not fall out. Pass the bolts through the support frame 12 and fix them with nuts to ensure the effective connection between the support frame 12 and the I-beam 11. Since the structure of the support frame 12 is a "U"-shaped structure, the left and right sides of the support frame 12 can be connected to the magnetic shielding assembly 2, thereby forming a continuous panel structure during the installation process.

[0032] Furthermore, in the present embodiment, a rotating unit 7 is provided on the magnetic shielding assembly 2. The rotating unit 7 in the present embodiment is a movable hinge. The two connecting pieces hinged by the movable hinge are respectively connected to the magnetic shielding assembly 2 and the support frame 12, so that the relative rotation between the magnetic shielding assembly 2 and the mounting frame can be realized, and the angle adjustment of the magnetic shielding assembly 2 is convenient; further, in the present embodiment, the movable hinge includes a fixing portion 71 connected to the support frame 12, wherein the fixing portion 71 is provided with an adjustment hole 72, and the adjustment hole 72 is a waist-shaped hole structure in the present embodiment. At the same time, a fixing member 121 is connected to the support frame 12, and the fixing member 121 is a bolt structure in the present embodiment. The fixing member 121 can pass through the adjustment hole 72 to connect and fix the rotating unit 7 (movable hinge) to the support frame 12. Further, during use, the relative position between the magnetic shielding assembly 2 and the support frame 12 can be adaptively adjusted, so as to adjust according to different construction requirements. Furthermore, in the present embodiment, teeth that can mesh with each other are provided on the support frame 12 and the fixing portion 71, so that the fixing portion 71 can mesh with the teeth when abutting against the support frame 12, thereby achieving a stable connection between the two, and can provide a reliable support effect for the magnetic shielding assembly 2 in the vertical direction; at the same time, in the present embodiment, a waist-shaped hole is provided on the support frame 12, and the setting direction of the waist-shaped hole is horizontal, which is perpendicular to the extension direction of the support member, so that the lateral position of the support frame 12 can be adjusted, thereby improving the adjustment flexibility of the support frame 12.

[0033] In this embodiment, the magnetic shielding assembly 2 includes a magnetic shielding panel 21, a frame 22, a damping layer 23, an insulating pad 24, a conductive layer panel 25, a non-magnetic transverse strip 26 and bolts for connection; wherein the frame 22 is spliced ​​by profile rods and angle codes, and insulating pads 24 are affixed to the upper and lower surfaces, and the magnetic shielding panel 21 is glued to the upper surface of the frame 22 by structural adhesive; the bolts pass through the non-magnetic transverse strip 26 to fix the magnetic shielding panel 21 on the rib in the middle of the frame 22, further stabilizing the magnetic shielding panel 21; the movable leaf on one side of the rotating unit 7 is installed on the lower surface of the frame 22 by screws, and the segmented damping layer 23 is filled between the magnetic shielding panel 21 and the conductive layer panel 25 to provide support and enhance rigidity.

[0034] Therefore, each component forms an independent magnetic shielding component 2, which can be assembled in a modular manner, thereby improving the efficiency of on-site construction. When two magnetic shielding components 2 are connected to the support frame 12, a gap will be formed in the middle area of ​​the support frame 12. Therefore, in this embodiment, the conductive layer cover plate 3 and the magnetic shielding cover plate 4 are respectively connected to the magnetic shielding component 2, and are bent according to the relative angles of the magnetic shielding components 2 on the adjacent two sides, so that the conductive layer cover plate 3 and the magnetic shielding cover plate 4 can cover the gap between the two magnetic shielding components 2, thereby minimizing the influence of the external magnetic field on the interior. Specifically, the magnetic shielding cover plate 4 is arranged above the magnetic shielding component 2, and the conductive layer cover plate 3 is arranged below the magnetic shielding component 2, and the conductive layer cover plate 3 is connected to the conductive layer panel 25, so that each magnetic shielding component 2 can be turned on, and the upper magnetic shielding cover plate 4 can ensure the integrity of the magnetic shielding effect and reduce the influence of leakage magnetic flux.

[0035] Furthermore, a non-magnetic pressure plate 6 is connected to the magnetic shielding cover plate 4, and the magnetic shielding cover plate 4 and the non-magnetic pressure plate 6 are connected by bolts passing through the magnetic shielding assembly 2, so that the edge of the magnetic shielding cover plate 4 can be fixed and constrained to prevent the magnetic shielding panel 21 and the magnetic shielding pressure cover from warping during force, transportation or installation; at the same time, the pressure on the panel after installation can be controlled more stably, which is more advantageous for some stress-sensitive magnetic shielding materials.

[0036] During use, the magnetic shielding component 2 is first assembled into an independent unit, and then the magnetic shielding component 2 is connected and assembled with the connected I-beam 11 and the support frame 12, and the magnetic shielding component 2, the support frame 12 and the connection relationship between the two are adjusted according to the required angle, and then after the magnetic shielding component 2 is fixed, the conductive layer cover plate 3 is connected to the conductive layer panel 25 of the magnetic shielding component 2 and fixed by bolts, and then a magnetic shielding cover plate 4 with a suitable bending angle is selected to be connected to the magnetic shielding component 2 and fixed by bolts; wherein the conductive layer cover plate 3 is made of copper, aluminum or a combination of copper and aluminum, and the material of the magnetic shielding cover plate 4 is selected from a magnetic shielding material with good shielding effect, and at the same time, the magnetic shielding cover plate 4 is set to a multi-layer structure, and the thickness of each layer is controlled to be thin, so as to achieve a good shielding effect, and the magnetic shielding cover plate 4 is set to be smaller on the side close to the conductive layer cover plate 3, and is set in a decreasing manner from top to bottom, so as to achieve a good magnetic shielding effect.

[0037] Embodiment 2: like Figure 5 As shown, unlike Example 1, in this embodiment, an adjustment vertical plate 5 is detachably connected to the base frame 1. By providing the adjustment vertical plate 5, it is possible to flexibly choose whether to install the adjustment vertical plate 5 to adjust the angle of the conductive layer cover plate 3 during the installation process. The flexibility of installation is improved. During use, the adjustment vertical plate 5 is adjusted to a suitable height or an adjustment vertical plate 5 of a suitable height is selected. The end of the adjustment vertical plate 5 is made to coincide with the bending line of the conductive layer cover plate 3 in the ideal position. Thereby, the bending degree of the conductive layer cover plate 3 can be corrected. After the correction is completed, the adjustment vertical plate 5 can be removed to avoid increasing the overall load.

[0038] The assembly and working process of the magnetic shielding material panel installation node structure in this embodiment are as follows: In this embodiment, an adjustment vertical plate 5 is connected to the base frame 1, and the adjustment vertical plate 5 is installed on the support frame 12. The support frame 12 is provided with a slide groove 13, and the slide groove 13 is integrally formed with the support frame 12 or fixed by bolt connection, welding, etc., so as to be connected with the adjustment vertical plate 5 for sliding and disassembly. The bottom shape of the adjustment vertical plate 5 matches the slide groove 13 so that it can be installed and disassembled as needed. The height of the adjustment vertical plate 5 is the same as the distance between the bending line of the conductive layer cover plate 3 and the slide groove 13 of the support frame 12 in an ideal state, thereby ensuring that under standard conditions, the bending line of the conductive layer cover plate 3 contacts the cone top 53 of the adjustment vertical plate 5, and at the same time, the conductive layer cover plates 3 on both sides can fit tightly with the magnetic shielding assembly 2.

[0039] During the installation process of this embodiment, the magnetic shielding assembly 2 is first assembled into an independent unit, and then combined with the connected I-beam 11 and support frame 12. According to the required angle, the magnetic shielding assembly 2, the support frame 12 and their connection relationship are adjusted. After the magnetic shielding assembly 2 is fixed, the conductive layer cover plate 3 is connected to the conductive layer panel 25 of the magnetic shielding assembly 2 and fixed with bolts. In this process, if there is a deviation between the bending angle of the conductive layer cover plate 3 and the actual required bending angle, the adjustment vertical plate 5 is slidably connected in the slide slot 13. At this time, the position of the cone top 53 of the adjustment vertical plate 5 is the bending line position of the magnetic shielding cover plate 4 in the ideal state. If the angle opening of the conductive layer cover plate 3 is too large, the bending line of the conductive layer cover plate 3 is abutted against the cone top 53, and then the conductive layer cover plates 3 on both sides are pressed to both sides until the magnetic shielding component 2 fits; and if the angle opening of the conductor layer cover plate is too small, the two sides of the conductive layer cover plate 3 are placed on the magnetic shielding component 2, and the middle position of the conductive layer cover plate 3 is pressed until the bending line abuts against the cone top 53, so that the conductive layer cover plate 3 and the magnetic shielding component 2 can be fitted. Next, select the magnetic shielding cover plate 4 with a suitable bending angle to connect to the magnetic shielding component 2 and fix it with bolts. The conductive layer cover plate 3 can be made of copper, aluminum or a combination of copper and aluminum, while the magnetic shielding cover plate 4 should be made of a material with good shielding effect. The magnetic shielding cover plate 4 is designed as a multi-layer structure, each layer is thin, so as to achieve a good shielding effect. In addition, the side of the magnetic shielding cover plate 4 close to the conductive layer cover plate 3 is smaller in size, and gradually decreases from top to bottom, thereby further improving the magnetic shielding effect.

[0040] Embodiment 3: like Figure 6 As shown, different from the embodiment 2, in this embodiment, the side of the adjusting riser 5 close to the conductive layer cover plate 3 is movably connected with a lifting plate 51, and the end of the lifting plate 51 close to the conductive layer cover plate 3 can abut against the bending line of the conductive layer cover plate 3. The height of the adjusting riser 5 can be adjusted by the lifting plate 51, so as to adapt to the magnetic shielding assembly 2 at different angles. The connection relationship between the adjusting riser 5 and the base frame 1 includes but is not limited to sliding connection, snap connection, bolt connection, and plug connection.

[0041] The assembly and working process of the magnetic shielding material panel installation node structure in this embodiment are as follows: In this embodiment, the base frame 1 is connected with an adjustment vertical plate 5, and the adjustment vertical plate 5 is installed on the support frame 12. The support frame 12 is provided with a slide groove 13, and the slide groove 13 is integrally formed with the support frame 12 or fixed by bolt connection, welding, etc., so as to be connected with the adjustment vertical plate 5 by sliding and disassembly. The bottom shape of the adjustment vertical plate 5 matches the slide groove 13, so that it can be installed and disassembled as needed. Among them, the adjustment vertical plate 5 includes a lifting plate 51, and the cone top 53 in this embodiment is set on the lifting plate 51. The height of the lifting plate 51 is the same as the distance between the bending line of the conductive layer cover plate 3 and the slide groove 13 of the support frame 12 in an ideal state, so as to ensure that under standard conditions, the bending line of the conductive layer cover plate 3 contacts the cone top 53 of the lifting plate 51, and at the same time, the conductive layer cover plates 3 on both sides can fit tightly with the magnetic shielding assembly 2.

[0042] Furthermore, in the present embodiment, the lifting plate 51 includes an adjusting block 512 with a lifting rod 511, and the lifting rod 511 is slidably connected to the adjusting vertical plate 5, and its bottom is in contact with the adjusting block 512. The contact surface between the adjusting block 512 and the lifting rod 511 is an inclined surface, and a connecting bearing is installed on the adjusting block 512, and the connecting bearing is connected to the adjusting bolt 513. By rotating the adjusting bolt 513, the adjusting block 512 can be driven to move, thereby lifting the lifting rod 511 and changing the position of the cone top 53. In this way, the position of the cone top 53 can be adjusted according to the angle of the magnetic shielding component 2 during installation to ensure that it matches the height of the bending line of the conductive layer cover plate 3, thereby ensuring that the conductive layer cover plate 3 is tightly fitted with the magnetic shielding component 2 after being adjusted into place.

[0043] During the installation process of this embodiment, the magnetic shielding assembly 2 is first assembled into an independent unit, and then combined with the connected I-beam 11 and support frame 12. According to the required angle, the magnetic shielding assembly 2, the support frame 12 and their connection relationship are adjusted. After the magnetic shielding assembly 2 is fixed, the conductive layer cover plate 3 is connected to the conductive layer panel 25 of the magnetic shielding assembly 2 and fixed with bolts. In this process, if there is a deviation between the bending angle of the conductive layer cover plate 3 and the actual required bending angle, the adjustment vertical plate 5 is slidably connected in the slide groove 13, and the position of the cone top 53 is adjusted according to the relative angle of the magnetic shielding cover plates 4 on the left and right sides, so that the position of the cone top 53 is at the intersection of the connecting line of the conductive layer panels 25 of the two magnetic shielding cover plates 4. If the angle opening of the conductive layer cover plate 3 is too large, the bending line of the conductive layer cover plate 3 is abutted against the cone top 53, and then the conductive layer cover plates 3 on both sides are pressed to both sides until the magnetic shielding component 2 fits; if the angle opening of the conductor layer cover plate is too small, the two sides of the conductive layer cover plate 3 are placed on the magnetic shielding component 2, and the middle position of the conductive layer cover plate 3 is pressed until the bending line abuts against the cone top 53, so that the conductive layer cover plate 3 and the magnetic shielding component 2 can be fitted. Next, select the magnetic shielding cover plate 4 with a suitable bending angle to connect to the magnetic shielding component 2 and fix it with bolts. The conductive layer cover plate 3 can be made of copper, aluminum or a combination of copper and aluminum, while the magnetic shielding cover plate 4 should be made of a material with good shielding effect. The magnetic shielding cover plate 4 is designed as a multi-layer structure, each layer is thin, so as to achieve a good shielding effect. In addition, the side of the magnetic shielding cover plate 4 close to the conductive layer cover plate 3 is smaller in size, and gradually decreases from top to bottom, thereby further improving the magnetic shielding effect.

[0044] Embodiment 4: like Figure 7 As shown, unlike Example 2, in this embodiment, a plurality of movable positioning pages 52 are hingedly connected to one end of the lifting plate 51 close to the conductive layer cover plate 3, and each movable positioning page 52 can move independently, and the movable positioning page 52 can rotate around the end of the lifting plate 51 to abut the magnetic shielding component 2. The lifting plate 51 is provided with movable positioning pages 52, and the movable positioning pages 52 are provided in a plurality and are not integral, so each movable positioning page 52 can move independently. Thus, it is possible to fit with the magnetic shielding components on both sides in a dispersed manner. Whether the end height of the lifting plate 51 is in an ideal position is determined by whether the degree of combination is complete. If the height of the lifting plate 51 is in an ideal state, the movable positioning page 52 can completely fit the magnetic shielding component 2, otherwise further adjustment is required. This structure can improve the efficiency and accuracy in the process of correcting the conductive layer cover plate 3.

[0045] The assembly and working process of the magnetic shielding material panel installation node structure in this embodiment are as follows: In this embodiment, the base frame 1 is connected with an adjustment vertical plate 5, and the adjustment vertical plate 5 is installed on the support frame 12. The support frame 12 is provided with a slide groove 13, and the slide groove 13 is integrally formed with the support frame 12 or fixed by bolt connection, welding, etc., so as to be connected with the adjustment vertical plate 5 by sliding and disassembly. The bottom shape of the adjustment vertical plate 5 matches the slide groove 13, so that it can be installed and disassembled as needed. Among them, the adjustment vertical plate 5 includes a lifting plate 51, and the cone top 53 in this embodiment is set on the lifting plate 51. The height of the lifting plate 51 is the same as the distance between the bending line of the conductive layer cover plate 3 and the slide groove 13 of the support frame 12 in an ideal state, thereby ensuring that under standard conditions, the bending line of the conductive layer cover plate 3 contacts the cone top 53 of the lifting plate 51, and at the same time, the conductive layer cover plates 3 on both sides can fit tightly with the magnetic shielding assembly 2.

[0046] Furthermore, in this embodiment, the lifting plate 51 includes a lifting rod 511 and an adjusting block 512. The lifting rod 511 is slidably connected to the adjusting vertical plate 5, and its bottom is in contact with the adjusting block 512. The contact surface between the adjusting block 512 and the lifting rod 511 is an inclined surface, and the adjusting block 512 is in contact with the adjusting bolt 513. By rotating the adjusting bolt 513, the adjusting block 512 can be driven to move, thereby lifting the lifting rod 511 and changing the position of the cone top 53; when the adjusting bolt 513 is reset, the lifting rod 511 presses down the adjusting block 512 by gravity, keeps the adjusting block 512 in contact with the adjusting bolt 513, and the lifting rod 511 descends. In this way, during installation, the position of the cone top 53 can be adjusted according to the angle of the magnetic shielding component 2 to ensure that it matches the height of the bending line of the conductive layer cover plate 3, thereby ensuring that the conductive layer cover plate 3 is tightly fitted with the magnetic shielding component 2 after being adjusted into place.

[0047] Furthermore, in the present embodiment, a movable positioning sheet 52 is provided at the position of the cone top 53, wherein the movable positioning sheet 52 is hinged on the cone top 53, and the movable positioning sheet 52 can rotate around the cone top 53, wherein a plurality of movable positioning sheets 52 are provided in the present embodiment, and each movable positioning sheet 52 can rotate independently, so that each movable positioning sheet 52 can be staggered and flipped to the conductive layer panels 25 of the magnetic shielding assembly 2 on the left and right sides as needed, so that the movable positioning sheet 52 can be staggered and flipped to the conductive layer panels 25 of the magnetic shielding assembly 2 on the left and right sides according to the needs, so that the magnetic shielding assembly 2 on the left and right sides can be staggered and flipped according to the needs of the movable positioning sheet 52. The degree of fit when the components 2 are butted together is used to judge whether the height of the cone top 53 is appropriate. According to different fitting states, the position of the cone top 53 is further adjusted so that the cone top 53 can be at a suitable height. At this time, the angle formed between the cone top 53 and the movable positioning pages 52 on the left and right sides is the same as the angle between the magnetic shielding components 2 on both sides. The conductive layer cover plate 3 can be adjusted by the cone top 53 and the movable pages to obtain a conductive layer cover plate 3 that meets the standards. Subsequently, the conductive layer cover plate 3 is installed after the adjustment vertical plate 5 is disassembled.

[0048] During the installation process of this embodiment, the magnetic shielding assembly 2 is first assembled into an independent unit, and then combined with the connected I-beam 11 and support frame 12. According to the required angle, the magnetic shielding assembly 2, the support frame 12 and their connection relationship are adjusted. After the magnetic shielding assembly 2 is fixed, the conductive layer cover plate 3 is connected to the conductive layer panel 25 of the magnetic shielding assembly 2 and fixed with bolts. In this process, if there is a deviation between the bending angle of the conductive layer cover plate 3 and the actual required bending angle, the adjustment vertical plate 5 is slidably connected in the slide groove 13, and the movable positioning leaf 52 is abutted against the magnetic shielding assembly 2 on the left and right sides during the sliding adjustment vertical plate 5 into the slide groove 13. When the adjustment vertical plate 5 is fully connected and enters the slide groove 13, the position of the cone top 53 is adjusted according to the relative angle of the magnetic shielding cover plates 4 on the left and right sides, so that the movable positioning leaf 52 can be completely fitted with the magnetic shielding assembly 2 on the left and right sides. When the movable positioning page 52 is fitted, the angle between the movable positioning page 52 on both sides is the same as the angle of the magnetic shielding components 2 on the left and right sides. At this time, the conductive layer cover plate 3 can be angle-corrected on the cone top 53 and the movable positioning page 52. After the conductive layer cover plate 3 is completely fitted with the movable positioning page 52, it means that the angle of the conductive layer cover plate 3 is the same as the angle of the magnetic shielding component 2. If the angle opening of the conductive layer cover plate 3 is too large, the bending line of the conductive layer cover plate 3 is abutted against the cone top 53, and then the conductive layer cover plates 3 on both sides are pressed to both sides until they are fitted with the magnetic shielding component 2; if the angle opening of the conductor layer cover plate is too small, the two sides of the conductive layer cover plate 3 are placed on the magnetic shielding component 2, and the middle position of the conductive layer cover plate 3 is pressed until the bending line abuts against the cone top 53, so as to achieve the fitting effect of the conductive layer cover plate 3 and the magnetic shielding component 2. Then remove the adjustment vertical plate 5 from the base frame 1, and install the conductive layer cover plate 3 on the magnetic shielding assembly 2. Next, select the magnetic shielding cover plate 4 with a suitable bending angle to connect to the magnetic shielding assembly 2 and fix it with bolts. The material of the conductive layer cover plate 3 can be selected from copper, aluminum or a combination of copper and aluminum, while the material of the magnetic shielding cover plate 4 should be selected from a material with good shielding effect. The magnetic shielding cover plate 4 is designed to be a multi-layer structure with a thin thickness of each layer to achieve a good shielding effect. In addition, the size of the magnetic shielding cover plate 4 is smaller on the side close to the conductive layer cover plate 3, and gradually decreases from top to bottom, thereby further improving the magnetic shielding effect.
