[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, when the staff installs the movable plate, one end of several limit plates close to the fixed plate is respectively inserted into the limit grooves located on the side surfaces of several connecting plates on the inner wall of the protective shell. When in use, the limit grooves can play a better guiding role in the movement of the movable plate through the limit plates, so that the movable plate is more stable when in use, and the magnetic field detectors on the several limit plates can detect the magnetic field strength at different positions inside the two protective shells. When the staff rotates the movable plate and the limit plate so that the limit plate drives several shielding cloths to protect the circuit board and shield the magnetic field, the several limit plates can support and limit the shielding cloth wrapped around the circuit board to prevent the shielding cloth from being wrapped around the surface of the circuit board.

[0018] 2. In the present invention, when several shielding cloths have completed the protection of the circuit board and the mounting plate, and the magnetic field detector can still detect a strong magnetic field around the circuit board protected by the shielding cloth, the staff can rotate the movable plate again, so that the limit plate and the connecting plate drive the several shielding cloths to wrap the circuit board and the mounting plate in multiple layers until the magnetic field detector detects that the magnetic field around the circuit board drops to the specified magnetic field strength and then stops rotating the movable plate. The staff can perform different degrees of magnetic field shielding and isolation on the circuit board according to the different magnetic field strengths detected in real time inside the protective shell, so that the circuit board can better receive, process and monitor information when in use.

[0019] 3. In the present invention, the outer wall of the mounting shaft is connected to the wrapped shielding cloth through a clockwork spring. When the limit plate pulls the connecting plate to move, the clockwork spring can cooperate with the limit plate to pull the two ends of the shielding cloth respectively, so that the position of the shielding cloth inside the protective shell is always in a taut state, preventing the surface of the shielding cloth from contacting the surface of the circuit board due to the excessive looseness of the position of the shielding cloth inside the protective shell during use.

[0020] 4. In the present invention, after the staff has adjusted the position of the movable plate, the staff can connect and fix the ends of the two protective shells away from the fixed plate to the movable plate by adjusting the bolts, and at the same time make the shielding cloth more stable when shielding the circuit board with the magnetic field. When the movable plate moves, the support block will be inserted into the bottom of the rotating plate and the protective plate in turn. When in use, the several exhaust holes on the end of the rotating plate away from the support rod can be located above the protective shell, and the outside air enters the inside of the protective shell through the fan blades and the air inlet holes, and can be discharged to the outside again through the grooves and the exhaust holes after the heat is dissipated on the surface of the circuit board, which can have a good heat dissipation effect on the circuit board when in use. At the same time, when the staff needs to inspect the circuit board or take the installation shaft and the shielding cloth thereon, they can directly rotate the two protective shells after disassembling the movable plate, so as to inspect the circuit boards on the two installation plates or disassemble and replace the shielding cloth.

[0036] As a technical optimization scheme of the present invention, a protective plate 14 is installed on the side of the rotating plate 7 close to the placement hole 13, and the protective plate 14 is located inside the placement hole 13.

[0038] As a technical optimization scheme of the present invention, a plurality of support blocks 26 matching the fixed groove 6 are installed on the side of the movable plate 3 close to the protective shell 2, and a guide angle 27 is provided at the corner position of the end of the support block 26 away from the movable plate 3, and the plurality of support blocks 26 are respectively located on both sides of the limit ring 21; when the staff installs the movable plate 3, the support block 26 can be inserted into the support chamfer 18 on the rotating plate 7 through the guide angle 27, and the rotating plate 7 is pushed to rotate as the movable plate 3 and the support block 26 move.

[0039] As a technical optimization scheme of the present invention, the two protective shells 2 are provided with a first screw hole 5 at the corner position away from the opposite surface at one end close to the movable plate 3, and the side of the movable plate 3 is provided with a fixing hole 28 matching the first screw hole 5 near the corner, and an adjusting bolt 4 is installed inside the fixing hole 28, and one end of the adjusting bolt 4 is threadedly installed in the first screw hole 5; when in use, after the limiting plate 19 is inserted into the limiting groove 12, the staff can rotate the movable plate 3 according to the usage situation, and after the position of the movable plate 3 and the connecting plate 8 is adjusted, the movable plate 3 and the two protective shells 2 can be connected by the adjusting bolt 4, so that the two protective shells 2 are more stable when in use.

[0040] As a technical optimization scheme of the present invention, an electric shaft 22 is rotatably installed on one side of the movable plate 3 close to the protective shell 2, a mounting sleeve 23 is installed on the outer wall of the electric shaft 22, and a plurality of fan blades 25 are installed on the outer wall of the mounting sleeve 23. The electric shaft 22, the mounting sleeve 23 and the fan blades 25 are all located inside the limiting ring 21; when in use, the electric shaft 22 can drive the plurality of fan blades 25 to rotate, so that the fan blades 25 can dissipate heat and circulate air to the inside of the protective shell 2 when they rotate.

[0041] As a technical optimization solution of the present invention, a plurality of air inlet holes 24 are opened on the side of the movable plate 3, and the end of the air inlet holes 24 close to the protective shell 2 is located inside the limiting ring 21, and the air inlet holes 24 are interconnected with the interiors of the two protective shells 2 through the limiting ring 21; when the fan blades 25 rotate, the outside air can enter the interior of the protective shell 2 through the air inlet holes 24, and carry the heat inside the protective shell 2 to the outside through the exhaust holes 17.

[0042] As a technical optimization scheme of the present invention, two mounting plates 29 are installed on one side of the fixing plate 1 close to the protective shell 2. The two mounting plates 29 are respectively located inside the two protective shells 2. Circuit boards 32 are installed on the opposite surfaces of the two mounting plates 29. Second screw holes 30 are opened on the sides of the circuit boards 32 and the mounting plates 29 near the corners. The internal threads of the second screw holes 30 are installed with fixing bolts 31. The mounting plates 29 are connected to the circuit boards 32 through the fixing bolts 31. When in use, the staff can install the circuit boards 32 on the opposite surfaces of the two mounting plates 29. Space is left between the two circuit boards 32 to facilitate air circulation inside the protective shell 2. At the same time, the four shielding cloths 15 can wrap the two circuit boards 32 to different degrees and provide magnetic field shielding protection.

[0043] When the present invention is in use, the staff can install circuit boards 32 on the opposite sides of the two mounting plates 29 on the side of the fixing plate 1, and the circuit boards 32 are connected to the fixing plate 1, and the external power information communication equipment is electrically connected to the circuit boards 32 through the fixing plate 1. The staff connects and fixes the circuit boards 32 and the mounting plates 29 with each other through the fixing bolts 31, and when in use, a space for air circulation is left between the two circuit boards 32, so as to facilitate heat dissipation of the circuit boards 32 when in use.

[0044] When the staff has finished installing the circuit board 32, the staff can rotate the protective shells 2 at both ends of the side of the fixed plate 1 so that the opposite surfaces of the two protective shells 2 abut against each other. When in use, the two protective shells 2 cooperate with each other to provide better protection for the two circuit boards 32. The staff installs the mobile plate 3 at one end of the two protective shells 2 away from the fixed plate 1, and when installing the mobile plate 3, the staff inserts several limiting plates 19 on the side limiting rings 21 of the mobile plate 3 close to the fixed plate 1 into the interior of the two protective shells 2, and inserts one end of the several limiting plates 19 close to the fixed plate 1 into the limiting grooves 12 on the sides of several connecting plates 8 on the inner wall of the protective shell 2. When in use, the limiting grooves 12 can guide the movement of the mobile plate 3 through the limiting plates 19, making the mobile plate 3 more stable when in use.

[0045] The staff pushes the movable plate 3 to move the end and the middle end of the limit plate 19 close to the fixed plate 1 to the inside of the limit groove 12. When in use, a magnetic field detector 20 is installed on the side of one end of several limit plates 19 close to the fixed plate 1. When the limit plates 19 are moved to the inside of the two protective shells 2, several magnetic field detectors 20 can detect the magnetic field strength at different positions inside the two protective shells 2 in real time. When in use, the magnetic field detector 20 is electrically connected to an external display, so that the magnetic field strength data detected by the magnetic field detector 20 at different positions are displayed on the display, which is convenient for the staff to understand the magnetic field strength inside the two protective shells 2 in real time.

[0046] When several magnetic field detectors 20 detect the magnetic field strength inside the two protective shells 2, the staff can rotate the movable plate 3 so that the movable plate 3 drives several limit plates 19 to rotate inside the two protective shells 2 through the limit ring 21. Because the limit plates 19 are slidably installed inside the limit grooves 12 on the connecting plates 8, when the several limit plates 19 rotate near the inner wall inside the two protective shells 2, they can drive several connecting plates 8 to slide inside the two protective shells 2 along the direction of the inner wall.

[0047] When the connecting plate 8 slides on the inner wall of the protective shell 2, the connecting plate 8 can pull the shielding cloth 15 on one side thereof, so that the shielding cloth 15 on the mounting shaft 10 inside the mounting hole 9 gradually moves through the connecting hole 11 to the inside of the protective shell 2, and moves with the connecting plate 8. When in use, a spring is provided on the outer wall of the mounting shaft 10, and is connected to the shielding cloth 15 wound and installed through the spring. When the limit plate 19 is disconnected from the connecting plate 8 during use, the shielding cloth 15 inside the protective shell 2 can be automatically retracted and wound on the outer wall of the mounting shaft 10 through the spring's own elasticity. When the limit plate 19 pulls the connecting plate 8 to move, the spring can cooperate with the limit plate 19 to pull the two ends of the shielding cloth 15 respectively, so that the position of the shielding cloth 15 inside the protective shell 2 is always in a tight state, so as to prevent the surface of the shielding cloth 15 from contacting the surface of the circuit board 32 due to the excessive looseness of the position of the shielding cloth 15 inside the protective shell 2 during use.

[0048] When the plurality of limit plates 19 drive the plurality of shielding cloths 15 to move to the inside of the protective shell 2 through the connecting plate 8 and slide along the inner wall of the protective shell 2, the plurality of shielding cloths 15 located inside the protective shell 2 can protect the two circuit boards 32 and the surrounding of the mounting plate 29. When the shielding cloths 15 protect the circuit boards 32 and the mounting plate 29, the limit plates 19 and the magnetic field detectors 20 thereon will also move along the inner wall direction of the protective shell 2, and the staff can understand the magnetic field strength at different positions inside the two protective shells 2 through the external display and the plurality of magnetic field detectors 20.

[0049] When several shielding cloths 15 have completed the protection of the circuit board 32 and the mounting plate 29, and the magnetic field detector 20 can still detect a strong magnetic field around the circuit board 32 under the protection of the shielding cloth 15, the staff can rotate the movable plate 3 again, so that the limit plate 19 and the connecting plate 8 drive several shielding cloths 15 to wrap the circuit board 32 and the mounting plate 29 in multiple layers, until the magnetic field detector 20 detects that the magnetic field around the circuit board 32 drops to the specified magnetic field strength and then stops rotating the movable plate 3. When in use, the staff can perform different degrees of magnetic field shielding and isolation on the circuit board 32 according to the different magnetic field strengths detected in real time inside the protective shell 2, so that the circuit board 32 can better receive, process and monitor information when in use.

[0050] After the shielding cloth 15 shields the circuit board 32 from the magnetic field, the staff can push the movable plate 3 again to move the limiting ring 21 on the side of the movable plate 3 to the inside of the two protective shells 2, so that the limiting ring 21 abuts against one end of the several connecting plates 8 close to the movable plate 3, which can play a certain limiting role on the several connecting plates 8 when in use, and the limiting ring 21 can seal the two protective shells 2 and the movable plate 3 to a certain extent. After the staff has adjusted the position of the movable plate 3, the staff can connect and fix the ends of the two protective shells 2 away from the fixed plate 1 to the movable plate 3 by adjusting the bolts 4, and the protective shell 2 also fixes the position of the limiting plate 19 and the shielding cloth 15 through the movable plate 3, so that the shielding cloth 15 is more stable when shielding the circuit board 32 from the magnetic field.

[0051] When the staff drives the limiting ring 21 to move to the inside of the protective shell 2 through the moving plate 3, one end of the support block 26 located on the side of the moving plate 3 will be inserted into the fixed groove 6 on the protective shell 2, and the end of the support block 26 close to the guide angle 27 will be inserted into the bottom of the end of the rotating plate 7 away from the support rod 33. With the movement of the moving plate 3, the end of the support block 26 close to the guide angle 27 will first be inserted into the support chamfer 18 at the bottom of the rotating plate 7. After that, the support block 26 can support the end of the rotating plate 7 away from the support rod 33, so that the rotating plate 7 rotates around the support rod 33. At the same time, the end of the protective plate 14 close to the support block 26 will also move out of the placement hole 13, and with the movement of the support block 26, the end of the support block 26 away from the moving plate 3 moves to the bottom of the end of the protective plate 14 close to the support rod 33. When in use, the plurality of exhaust holes 17 on the end of the rotating plate 7 away from the support rod 33 can be located above the protective shell 2.

[0052] When in use, the electric shaft 22 drives the plurality of fan blades 25 to rotate through the mounting sleeve 23, and when the fan blades 25 rotate, the outside air enters the inside of the two protective shells 2 through the plurality of air inlet holes 24, and the fan blades 25 can blow the air toward the surface of the circuit board 32, and make the air flow inside the two protective shells 2, and when in use, the flowing air can dissipate heat from the surface of the circuit board 32 inside the protective shell 2. When the air entering the inside of the protective shell 2 gradually increases, the air pressure inside the protective shell 2 will increase, so that the air after dissipating heat from the surface of the circuit board 32 enters the groove 16 on the protective plate 14, and is discharged to the outside through the plurality of exhaust holes 17 on both sides of the inner wall of the groove 16, and can play a good heat dissipation role for the circuit board 32 inside the two protective shells 2 when in use.

[0053] When the staff needs to inspect the circuit board 32 or take the mounting shaft 10 and the shielding cloth 15 thereon, they can directly rotate the two protective shells 2 after disassembling the movable plate 3, so as to inspect the circuit board 32 on the two mounting plates 29 or disassemble and replace the shielding cloth 15, which is more convenient when inspecting the circuit board 32.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
