Description
Technical Field
[0001] The utility model relates to the technical field of shielding rooms, in particular to a sound-insulating and electromagnetic-wave-resistant shielding room. Background Art
[0002] The shielding room is made of magnetic materials. The parameter that measures the magnetic conductivity of the material is magnetic permeability. The higher the magnetic permeability, the better the shielding effect. The common ordinary high magnetic permeability material is cold-rolled steel plate, and the thickness of the shielding body plays a decisive role. The stronger the magnetic field strength, the thickness of the shielding material should also be increased accordingly. The principle of the shielding room is that the shielding system composed of shielded cables and shielded components will be the best choice. It has passed interference and eavesdropping experiments, divergence tests, bit error rate tests, and anti-interference experiments.
[0003] For example, a Chinese patent (publication number: CN215529771 U) discloses a shielding room that is resistant to electromagnetic wave interference, including a shielding room body, a room door is installed at the front end of the shielding room body, and a sealing anti-interference structure is arranged between the room door and the shielding room body; the sealing anti-interference structure includes a edging metal plate, an upper pressure sealing pad, a butt sealing pad and a pressing groove. The utility model shielding room that is resistant to electromagnetic wave interference can effectively increase its internal shielding effect. By arranging an anti-reflection pad, it can reduce the reflection and superposition of electromagnetic waves inside on the inner wall to avoid interference affecting the internal effect. The room door is sealed by the sealing anti-interference structure, which can effectively ensure its internal shielding effect when closed, improve its anti-interference ability, and thus adjust its ventilation efficiency. The honeycomb ventilation holes are all steel waveguide air holes, which can change the internal environmental conditions without affecting its shielding properties, and can be adjusted as needed to meet the needs of the use environment.
[0004] The above-mentioned shielding room against electromagnetic interference still has certain shortcomings. By setting anti-reflection pads, the reflection and superposition of electromagnetic waves inside on the inner wall can be reduced to avoid interference affecting the internal effect. The door is sealed by a sealed anti-interference structure, which can effectively ensure the internal shielding effect when closed and improve its anti-interference ability, thereby adjusting its ventilation efficiency. However, there is a lack of limit between the shielding room body and the door, resulting in poor sealing between the shielding room body and the door, affecting the anti-electromagnetic interference effect of the shielding room body. Therefore, a soundproof and anti-electromagnetic interference shielding room is proposed to solve the above problems. Utility Model Content

[0023] Please refer again Figure 2In order to improve the sealing effect, the sealing mechanism 3 in this embodiment includes an electric push rod 301 fixed to the right side of the inner cavity of the shielding door 2, and a moving block 302 is fixed to the output end of the electric push rod 301. Two hinged rods 305 are hinged on the upper and lower sides of the moving block 302, and two first clamping rods 303 are fixed on the left side of the moving block 302. The upper and lower sets of hinged rods 305 are hinged on the opposite sides of each other. A plurality of second clamping rods 307 are fixed on the opposite sides of the two moving plates 306. The sealing mechanism 3 also includes a plurality of first clamping grooves 304 opened on the left side of the inner cavity of the shielding room body 1 and a plurality of second clamping grooves 308 opened on the upper and lower sides of the inner cavity of the shielding room body 1.
[0024] Among them, the first clamping rod 303 is slidably connected to the inside of the first clamping slot 304, and the second clamping rod 307 is slidably connected to the inside of the second clamping slot 308. The first clamping rod 303 is clamped into the inside of the first clamping slot 304, and the second clamping rod 307 is clamped into the inside of the second clamping slot 308, so as to seal the shielding room body 1 and the shielding door 2, improve the sealing performance, and facilitate anti-electromagnetic interference.
[0025] In addition, T-shaped blocks are fixed on both sides of the movable plate 306, and two T-shaped slots are provided on both sides of the inner cavity of the shielding door 2. The T-shaped blocks are slidably connected to the inside of the T-shaped slots to increase the stability of the movable plate 306 when moving.
[0026] In addition, a circular fixing plate is fixed to the inner cavity wall of the shielding room body 1, a sealing ring is fixed to the front of the circular fixing plate, and the back of the shielding door 2 abuts against the front of the sealing ring to limit the shielding door 2. The sealing performance between the shielding room body 1 and the shielding door 2 is improved by cooperating with the sealing ring and the sealing mechanism 3.
[0027] In the sealing mechanism 3 of this embodiment, the electric push rod 301 pushes the moving block 302 and the first clamping rod 303 to move together, so that the first clamping rod 303 is clamped into the first clamping groove 304, and the moving block 302 pushes the moving plate 306 to move through the hinge rod 305, and drives the second clamping rod 307 to be clamped into the inside of the second clamping groove 308 through the moving plate 306, so as to seal the shielding door 2 and the shielding room body 1, thereby improving the sealing performance of the shielding room body 1 and the shielding door 2.

The anti-electromagnetic layer 403 is carbon fiber. The carbon fiber material has high electrical conductivity and can absorb the energy of electromagnetic waves. When electromagnetic waves pass through the carbon fiber, their energy will be conducted to the inside of the carbon fiber and converted into heat energy. This absorption effect can effectively reduce the propagation and reflection of electromagnetic waves, thereby reducing the impact of electromagnetic radiation on the surrounding environment. The protective layer 404 is polyarylate, which has good creep resistance, toughness, strain recovery, wear resistance and high surface hardness, small linear expansion coefficient, low hygroscopicity and high dimensional stability.

[0031] The working principle of the above embodiment is:
[0032] (1) When the shielding door 2 needs to be sealed, the shielding door 2 is pushed to rotate so that the shielding door 2 abuts against the sealing ring on the circular fixed plate, and the electric push rod 301 is started. The electric push rod 301 pushes the moving block 302 to move leftward, and the moving block 302 drives the first clamping rod 303 to be clamped into the first clamping groove 304. At the same time, the moving block 302 drives the hinged rod 305 to rotate. The moving block 302 pushes the moving plate 306 to move through the hinged rod 305. The moving plate 306 drives the T-shaped block to slide inside the T-shaped groove, thereby increasing the stability of the moving plate 306 when moving. The second clamping rod 307 is driven to move through the moving plate 306, and the second clamping rod 307 is clamped into the second clamping groove 308, thereby sealing the shielding door 2 and the shielding room body 1, thereby improving the sealing of the shielding room body 1 and the shielding door 2, which is beneficial to improving the sound insulation and anti-interference performance.
[0033] (2) The sound insulation mechanism 4 is composed of a first sound insulation layer 401, a second sound insulation layer 402, an anti-electromagnetic layer 403 and a protective layer 404. The first sound insulation layer 401 is a gypsum board, which is a material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire resistance. The second sound insulation layer 402 is a honeycomb sound absorbing board, which has a large board surface, high flatness, high board strength, light weight, good sound absorption effect, fire resistance, waterproofness and easy installation. The anti-electromagnetic layer 403 is carbon fiber, which can absorb the energy of electromagnetic waves. When electromagnetic waves pass through the carbon fiber, their energy will be conducted to the inside of the carbon fiber and converted into heat energy. This absorption effect can effectively reduce the propagation and reflection of electromagnetic waves. The protective layer 404 is polyarylate, which has good creep resistance, toughness, strain recovery, wear resistance and high surface hardness, thereby improving the sound insulation performance, anti-electromagnetic performance and protection performance of the shielding room body 1.
