[0002] A Faraday cage is a cage made of metal or a good conductor, with a metal shell to prevent electromagnetic fields from entering or escaping. In the existing technology, Faraday cages are generally made by welding round steel mesh, and the round steel meshes must meet the overlapping requirements. The decorative surface layer is then applied after the Faraday cage is constructed. However, the welding operation of round steel mesh is relatively complicated, which makes the production of Faraday cages time-consuming and labor-intensive. Utility Model Content

[0003] This invention provides a Faraday cage based on a perforated plate to solve the problem that the manufacturing of Faraday cages in the prior art is time-consuming and labor-intensive.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A Faraday cage based on perforated plates includes multiple splicable Faraday cage perforated plates; fastening shims one and two fastening shims are installed between two of the Faraday cage perforated plates for limiting the position of the Faraday cage perforated plates, and fastening shims one fastens to Faraday cage perforated plates on the same plane, while fastening shims two fasten to Faraday cage perforated plates on different planes; rivets are installed at both ends of the fastening shims one for cooperating with the Faraday cage perforated plates to fasten the fastening shims one, and the rivets are simultaneously installed at both ends of the fastening shims two.

[0006] Furthermore, the Faraday cage perforated plate has multiple cavities in the middle, and a base is installed at the bottom of the Faraday cage perforated plate.

[0007] Furthermore, the fastening washer includes a square block, with positioning holes for rivet insertion at both ends of the square block, connecting blocks installed at both ends of the square block, and a locking block installed on one side of the connecting block.

[0008] Furthermore, both sides of the square block are provided with a limiting groove for limiting the connecting block, and one side of the limiting groove is provided with a slot for limiting the locking block.

[0009] Furthermore, connecting pipes are installed at both ends of the square block near the limiting groove one. The outer wall of the connecting pipe is machined with arc-shaped sharp locking blocks for engaging with the inner wall of the cavity. Multiple vertical grooves are opened in the middle of the connecting pipe, and a connecting groove two is opened at one end of the vertical groove.

[0010] Furthermore, the rivet includes a limiting disc, one end of which is connected to a sleeve, one end of which is connected to a round head, and the middle of the sleeve is provided with multiple connecting grooves to facilitate sleeve deformation.

[0011] Furthermore, the second fastening pad includes a V-shaped block, with positioning holes two at both ends of the V-shaped block, and a sleeve inserted into positioning holes one and two. Connecting blocks two are installed at both ends of the V-shaped block, and a locking block two is installed on one side of the connecting blocks two.

[0012] Furthermore, the two ends of the V-shaped block are provided with limiting grooves for limiting the connecting block two, and one side of the limiting grooves is provided with a slot for limiting the locking block two.

[0013] This utility model has the following advantages:

[0014] This invention, through the setting of fastening shims one and two, allows for the rapid assembly of Faraday cage perforated plates into a Faraday cage. The operation is simple, eliminating the need for welding between multiple steel meshes. Furthermore, the connecting pipe design ensures that when the rivets are tightened, the deformed end of the sleeve presses against the inner wall of one side of the connecting pipe, causing the arc-shaped sharp locking block to clamp onto the inner wall of the cavity. This increases the stability between the square block and the Faraday cage perforated plate, making it less likely for the fastening shim one and the Faraday cage perforated plate to loosen during the transportation of the Faraday cage.

[0023] Please see Figures 1-5 This utility model provides a Faraday cage based on a perforated plate, including multiple splicable Faraday cage perforated plates 10, and multiple cavities 11 are opened in the middle of the Faraday cage perforated plate 10. A base 12 is installed at the bottom of the Faraday cage perforated plate 10, and the base 12 and the Faraday cage perforated plate 10 at the upper end of the base 12 are fixed by welding.

[0024] Two fastening shims 100 and 200 are installed between the two Faraday cage perforated plates 10 to limit the movement of the Faraday cage perforated plates 10. The fastening shim 100 is fastened to the Faraday cage perforated plates 10 on the same plane, and the fastening shim 200 is fastened to the Faraday cage perforated plates 10 on different planes, so that multiple Faraday cage perforated plates 10 can be spliced ​​into a frame.

[0025] Both ends of the first fastening washer 100 are fitted with rivets 20 for fastening the first fastening washer 100 in conjunction with the Faraday cage perforated plate 10. The rivets 20 are also installed at both ends of the second fastening washer 200. The rivet 20 includes a limiting disc 21, one end of which is fixedly connected to a sleeve 22. The sleeve 22 passes through the cavity 11, and one end of the sleeve 22 is fixedly connected to a round head 23. The middle of the sleeve 22 is provided with multiple connecting grooves 24 to facilitate the deformation of the sleeve 22. The rivet 20 is an existing structure and can be fixed to the first fastening washer 100 and the second fastening washer 200 by an electric rivet gun.

[0026] The fastening washer 100 includes a square block 110. Positioning holes 111 for inserting rivets 20 are provided at both ends of the square block 110. Connecting blocks 112 are fixedly installed at both ends of the square block 110. A locking block 113 is fixedly installed on one side of the connecting block 112. Limiting grooves 114 for limiting the connecting block 112 are provided on both sides of the square block 110. A locking groove 115 for limiting the locking block 113 is provided on one side of the limiting groove 114. After the connecting block 112 is inserted into the limiting groove 114 and the locking block 113 is inserted into the locking groove 115, the two fastening washers 100 that are close together are not easily separated, making the connection between the Faraday cage perforated plates 10 more secure and less prone to detachment.

[0027] A connecting pipe 120 is fixedly installed at both ends of the square block 110 near the limiting groove 114. The outer wall of the connecting pipe 120 is machined with an arc-shaped sharp locking block 123 for engaging with the inner wall of the cavity 11. Multiple vertical grooves 121 are opened in the middle of the connecting pipe 120. A connecting groove 122 is opened at one end of the vertical groove 121. The setting of the vertical groove 121 and the connecting groove 122 facilitates the deformation of the end of the connecting pipe 120 with the vertical groove 121.

[0028] When rivet 20 fixes the square block 110 onto the Faraday cage perforated plate 10, connecting pipe 120 is inserted into cavity 11, and sleeve 22 is inserted into the middle of connecting pipe 120. When the electric rivet gun controls the deformation of rivet 20, the round head 23 moves closer to the Faraday cage perforated plate 10, and after the sleeve 22 deforms, the sleeve 22, together with the limiting plate 21, clamps the square block 110 onto the Faraday cage perforated plate 10, and the sleeve... When the sleeve 22 deforms, the deformed end of the sleeve 22 will squeeze the inner wall of one side of the connecting pipe 120, so that the arc-shaped sharp locking block 123 is locked in the inner wall of the cavity 11, thereby increasing the stability between the square block 110 and the Faraday cage perforated plate 10, so that during the transportation of the Faraday cage, the fastening gasket 100 and the Faraday cage perforated plate 10 are not prone to loosening, and there will be no loosening between two adjacent Faraday cage perforated plates 10.

[0029] The fastening gasket 200 includes a V-shaped block 210, which comprises a horizontal plate and a vertical plate, with the included angle between the horizontal and vertical plates being 90 degrees. The V-shaped block 210 is installed on two perpendicular Faraday cage perforated plates 10 to fasten the two perpendicular Faraday cage perforated plates 10. Positioning holes 211 are provided at both ends of the V-shaped block 210, and sleeves 22 can be inserted into positioning holes 111 and 211. Connecting blocks 212 are fixedly installed at both ends of the V-shaped block 210. A locking block 213 is installed on one side of the connecting block 212. The size and structure of the second locking block 213 and the first connecting block 112 are the same. The two ends of the V-shaped block 210 are provided with multiple limiting grooves 214 for limiting the second connecting block 212. One side of the limiting groove 214 is provided with a locking slot 215 for limiting the second locking block 213. The size and structure of the limiting groove 214, the locking slot 215 and the first limiting groove 114, the locking slot 115 are the same, so that the first limiting groove 114 and the locking slot 115 can be locked into the second limiting groove 214 and the locking slot 215, thereby increasing the fastening between adjacent Faraday cage perforated plates 10.

[0030] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
