Put the rubber sleeve 32 on the outer layer of the frame 1, weld the back plate 5 inside the frame 1, then fix the two second partitions 16 on both sides of the frame 1 respectively through the cooperation of the cross bar 7 and the first hexagonal nut 8, fix the top plate 2 and the bottom plate 3 on the top and bottom of the frame 1 respectively through the cooperation of the vertical bar 9 and the second hexagonal nut 10, and complete the installation of the second partition 16, the first partition 14 and the frame 1 through the second U-shaped buckle 17 and the first U-shaped buckle 15 respectively with the buckle of the vertical bar 9 and the cross bar 7, finally slide the rain shield 30 on the top of the top plate 2, rotate the door plate 24 to one side of the frame 1, and connect the top plate 2, the bottom plate 3, the side plate 4, the back plate 5 and the door plate 24 to the frame 1 through the first contact piece 11, the wire 12 and the second contact piece 13 respectively, to complete the installation of the whole device; S2. Since the top plate 2, the bottom plate 3, the side plate 4, the back plate 5 and the door plate 24 are all connected to the frame 1 through the wire 12, the top plate 2, the bottom plate 3, the side plate 4, the back plate 5, the door plate 24 and the frame 1 form excellent conductivity, which is equivalent to a Faraday cage, greatly enhancing the anti-electromagnetic interference function, and the frame 1 is grounded through the guide rod 39, pouring the magnetic field gathered on the frame 1 into the ground; in addition, the top plate 2, the bottom plate 3, the side plate 4, the back plate 5 and the door plate 24 are all low magnetic permeability materials, and the first partition 14, the second partition 16 and the third partition 18 are high magnetic permeability materials, forming a double-layer shielding, the first layer of shielding formed by the low magnetic permeability first reduces the magnetic field to an appropriate intensity, and the second layer of shielding formed by the high magnetic permeability material is not easy to be saturated, thereby further enhancing the anti-electromagnetic interference function; S3. When in use, a heat insulation cavity 21 is formed between the second partition plate 16 and the side plate 4, the first partition plate 14 and the top plate 2 and the bottom plate 3, and the third partition plate 18 and the back plate 5. The heat insulation cavity 21 can form a heat insulation effect on the inside of the frame 1, and the first heat dissipation hole 20 and the first ventilation hole 19 can cooperate to discharge the heat in the frame 1 to the outside; S4. When inspecting the interior of the frame 1 in the rainy season, the door panel 24 is opened. The door panel 24 pulls the rain shield 30 outward through the cooperation of the sliding pin 28 and the slide groove 31. The rain shield 30 can block rainwater to prevent rainwater from splashing into the interior of the frame 1. When the rain shield 30 moves, the magnetic attraction of the magnet 36 and the U-shaped baffle 34 drives the U-shaped baffle 34 to move. The U-shaped baffle 34 just blocks the heat dissipation pipe 33 to prevent rainwater from penetrating into the heat insulation cavity 21 through the heat dissipation pipe 33. When the frame 1 is opened on a sunny day, the sliding pin 28 is pulled downward to release the cooperation between the sliding pin 28 and the slide groove 31. Therefore, after the door panel 24 is opened, the rain shield 30 remains stationary to prevent the rain shield 30 from moving to block the sunlight and affect the sight of the staff. S5. In addition, the hot air between the back plate 5 and the third partition plate 18 can be discharged to between the top plate 2 and the rain shield 30 through the heat dissipation pipe 33. In addition, the cross-sectional area between the rain shield 30 and the top plate 2 is small, so the cold air from the outside is accelerated to flow in the rain shield 30, quickly blowing away the hot air discharged from the heat dissipation pipe 33, thereby accelerating the heat dissipation function of the frame 1.
