Electromagnetic shielding rooms are an important part of the field of electromagnetic compatibility. An electromagnetic shielding room is essentially a steel plate house, with cold-rolled steel plates as its main shielding material.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Reference Figure 1-4 This utility model provides a soundproof electromagnetic shielding door, comprising:
[0035] The frame includes two sets of tracks 1 and two sets of side plates. The two sets of tracks 1 are fixed to the top and bottom of the shielded room door opening, respectively, and the two sets of side plates are fixed to both sides of the shielded room door opening, and the tracks 1 and the side plates together form a rectangular structure.
[0036] The shielded door body includes a door frame 2, an inner door panel 3, and an outer door panel 4. The door frame 2 is positioned between two sets of tracks 1. The inner door panel 3 and the outer door panel 4 are symmetrically fixed to the door frame 2. A cavity is formed between the inner door panel 3, the outer door panel 4, and the door frame 2, and the cavity is vacuum-treated. Sound insulation can also be achieved by installing sound insulation cotton between the inner door panel 3 and the outer door panel 4. The inner door panel 3, the outer door panel 4, and the door frame 2 are sealed with sealant to ensure that the cavity formed by the door frame 2 and the inner door panel 3 and the outer door panel 4 is completely sealed and to prevent air leakage.
[0037] The sliding components are slidably connected to the track 1, and the sliding components are rotatably connected to the door frame 2;
[0038] The boom is rotatably connected to two sets of tracks 1, and a slider 11 is rotatably connected to one end of the boom. The slider 11 is slidably connected to the door frame 2.
[0039] The sealing components are provided in two sets, which are respectively installed at the upper and lower ends of the outer door panel 4 and abut against the door frame 2.
[0040] Among them, the two sets of side panels abut against the inner and outer sides of the door frame 2 respectively. The outer surface of the door frame 2, the inner door panel 3, and the outer door panel 4 are respectively fixed with copper sheets, and the copper sheets on the side panels extend to the shielding layer of the isolation chamber.
[0041] The operator stands on the side of the shielded door away from the sliding components, preparing to open the sliding door. At this time, the shielded door is closed, with the door frame 2 parallel to and fitted with the two sets of tracks 1. The two sets of side panels are tightly abutted against the inner and outer sides of the door frame 2, respectively. The sealing components are installed at the upper and lower ends of the outer door panel 4 and abut against the door frame 2. The cavity is kept in a vacuum state, and all components are in their initial stable positions. The operator applies a pushing or pulling force to the side of the shielded door away from the sliding components, and the door frame 2 begins to move under the force. Since the sliding components are slidably connected to the tracks 1 and rotatably connected to the door frame 2, the door frame 2 begins to slide along the tracks 1. Simultaneously, the sliding components slide synchronously on the tracks 1, ensuring smooth movement of the door frame 2. As the door frame 2 moves, the slider 11 rotatably connected to one end of the boom slides on the door frame 2, and the boom gradually extends. A variable triangular structure is formed between the boom, tracks 1, and door frame 2. This triangular structure supports the shielded door body, ensuring the stability of the door frame 2 during movement and preventing it from swaying or tilting. Under the action of the sliding assembly, door frame 2 not only slides but also rotates to a certain extent during movement due to the support and guidance of the boom. At this time, the main body of the shielded door and the track 1 are arranged in an alternating manner. This alternating arrangement ensures that the main body of the shielded door has sufficient opening and closing angles while reducing the operating space, making it convenient for operators to open the door in a limited space. The operator continuously applies pushing or pulling force until the main body of the shielded door is fully opened to the desired position. At this time, the door frame 2, boom, track 1, and other components form a stable support structure, ensuring the stability of the main body of the shielded door in the open state and preventing it from automatically closing due to external forces. The operator stands on the side of the shielded door main body closer to the boom, ready to push the door. At this time, the main body of the shielded door is in the fully open state, and the door frame 2, boom, track 1, and other components form a stable support structure with their positions relatively fixed. The operator applies pushing force to the side of the shielded door main body closer to the boom, and door frame 2 begins to move under the action of force. The sliding assembly slides on track 1, guiding the door frame 2 to move along track 1 in the closing direction. Simultaneously, the slider 11, rotatably connected to one end of the boom, slides in the opposite direction on the door frame 2, causing the boom to gradually retract. As the door frame 2 moves, the boom gradually retracts to its initial state, and the door frame 2, guided by the sliding assembly, gradually returns to a position parallel to the two sets of tracks 1. At this time, the contact between the door frame 2 and the side panels gradually returns, ensuring the stability of the door frame 2 during movement. When the door frame 2 moves to near the closed position, the sealing assembly installed at the upper and lower ends of the outer door panel 4 begins to contact the door frame 2. The sealing assembly acts as a seal, preventing external sound and electromagnetic waves from entering the shielded room through the door gap. The operator continues to apply pushing force until the shielded door body is completely closed. At this time, the door frame 2 is completely parallel and fitted with the two sets of tracks 1, the two sets of side panels are tightly contacted with the inner and outer sides of the door frame 2 respectively, and the sealing assembly is completely contacted with the door frame 2, forming a good sealing effect.The cavity is kept in a vacuum state, and the copper sheets are well fixed on the outer surface of the door frame 2, the inner door panel 3, the outer door panel 4, and the side panels. The copper sheets on the side panels extend to the shielding layer of the isolation chamber to ensure the electromagnetic shielding effect.
[0042] The cavity formed between the inner door panel 3, the outer door panel 4, and the door frame 2 of the soundproof electromagnetic shielding door is vacuum-treated. Sound cannot propagate in a vacuum, greatly reducing the possibility of sound entering the shielding room from the outside and exiting from the shielding room to the outside, effectively blocking mid-to-high frequency noise. The door frame 2, the inner door panel 3, and the outer door panel 4 constitute a multi-layered composite structure. This multi-layered structure increases the path and difficulty of sound propagation; when sound encounters each layer of the structure, some energy is reflected and absorbed. It's like setting up multiple soundproof walls in a room; each wall can block and weaken sound to a certain extent, further improving the sound insulation effect. Sealing components are installed at the top and bottom ends of the outer door panel 4, abutting against the door frame 2. When the door is closed, the sealing components can tightly fit against the door frame 2, filling the gap between the door and the door frame 2, preventing sound leakage from the gap. This enhances the overall sound insulation performance of the door. The two sets of side panels abut against the inner and outer sides of the door frame 2 respectively. This tight abutment further reduces the channels for sound leakage, creating a relatively enclosed space between the door and the doorway of the shielding room, effectively preventing the entry of external noise and the leakage of internal sound.
[0043] Copper sheets are fixed to the outer surface of door frame 2, the inner door panel 3, the outer door panel 4, and the side panels, with the copper sheets on the side panels extending to the shielding layer of the isolation chamber. Copper is a good conductor and has excellent electromagnetic shielding performance. When electromagnetic waves encounter copper sheets, induced currents are generated on the surface of the copper sheets. These induced currents generate magnetic fields opposite to the original electromagnetic waves, thereby canceling out the original electromagnetic waves and achieving the purpose of shielding electromagnetic waves. The copper sheets fixed in various parts are interconnected to form a complete electromagnetic shielding system. From door frame 2 to door panels, then to side panels, and the copper sheets extending to the shielding layer, the entire structure of the door and the connection points with the shielding chamber are covered, ensuring that electromagnetic waves cannot enter or exit the shielding chamber through the door, providing a reliable electromagnetic environment for the shielding chamber.
[0044] Further optimization of the scheme: the sliding component includes a mounting frame 5, on which two sets of pulleys 6 are rotatably connected. The pulleys 6 are slidably connected to the track 1. A support base 7 is fixedly connected to the mounting frame 5. A fixing block 8 is rotatably connected to the top surface of the support base 7. The fixing block 8 is fixedly connected to the bottom of the door frame 2. A positioning module is installed on the mounting frame 5.
[0045] Two sets of pulleys 6 on the mounting bracket 5 are slidably connected to the track 1, and the door frame 2 moves by the rolling of the pulleys 6 on the track 1. The fixed block 8, which is rotatably connected to the top surface of the support base 7, is fixed to the bottom of the door frame 2, so that the door frame 2 can slide with the pulleys 6 and rotate around the fixed block 8 at a certain angle during the movement, thereby realizing the staggered arrangement of the door frame 2 during the opening process. The elastic telescopic rod of the positioning module corresponds to the positioning block on the track 1. When the door frame 2 moves to a specific position (such as the closed or fully open position), the elastic telescopic rod contacts the positioning block, which plays a positioning and buffering role and prevents the door frame 2 from moving excessively.
[0046] When opening the door, the operator pushes the door frame 2, causing the pulley 6 to roll on the track 1, which in turn moves the mounting bracket 5, thus causing the door frame 2 to begin moving. Simultaneously, the door frame 2 rotates around the fixed block 8, achieving an alternating arrangement. When the door frame 2 reaches the open position, the elastic telescopic rod contacts the positioning block, completing the positioning. When closing the door, pushing the door frame 2 in the opposite direction causes the pulley 6 to roll in the opposite direction, returning the door frame 2 to the closed position, and the elastic telescopic rod contacts the positioning block again for positioning.
[0047] The design is further optimized. The boom includes a boom 9, one end of which is rotatably connected to the end of the track 1. A support block 10 is fixedly connected to one end of the boom 9. A slider 11 is rotatably connected to the top surface of the support block 10. A groove 12 is provided on the bottom surface of the door frame 2. The slider 11 is slidably connected in the groove 12.
[0048] The boom 9 has a rotation angle of 0°-60°.
[0049] One end of the arm 9 is rotatably connected to the end of the track 1, and the other end is rotatably connected to the slider 11 via the support block 10, which is slidably connected to the groove 12 on the bottom surface of the door frame 2. When the door frame 2 moves, the slider 11 slides in the groove 12, causing the arm 9 to rotate. The rotatable angle of the arm 9 is 0°-60°. The rotation of the arm 9 provides support for the door frame 2, ensuring the stability of the door frame 2 during movement.
[0050] When the door opens, the door frame 2 moves, the slider 11 slides within the groove 12, pushing the arm 9 to rotate. The arm 9 gradually extends, providing support for the door frame 2. When the door closes, the door frame 2 moves in the opposite direction, the slider 11 slides in the opposite direction, and the arm 9 gradually retracts, returning to its initial state.
[0051] Further optimization of the scheme: the enclosure component includes an enclosure plate 13, which is slidably connected to the upper and lower ends of the outer door panel 4. The cross-sectional shape of the enclosure plate 13 is a U-shaped structure. An installation plate 15 is fixedly connected to the outer door panel 4. The installation plate 15 is located in the groove of the enclosure plate 13. A connecting rod 14 is vertically slidably connected to the installation plate 15. The connecting rod 14 is fixed to the bottom wall of the groove on the enclosure plate 13. A spring 16 is sleeved on the connecting rod 14. The spring 16 is fixed to the bottom surface of the installation plate 15 and the enclosure plate 13.
[0052] The sealing plate 13 is slidably connected to the upper and lower ends of the outer door panel 4, and is elastically connected to the outer door panel 4 through the connecting rod 14, the mounting plate 15, and the spring 16. When the door is closed, the sealing plate 13 is tightly pressed against the door frame 2 under the action of the spring 16, which plays a sealing role and prevents sound and electromagnetic wave leakage.
[0053] When the door is opened, as the door frame 2 moves, the sealing plate 13 remains in contact with the door frame 2 under the action of the spring 16. However, due to the movement of the door frame 2, the relative position between the sealing plate 13 and the door frame 2 changes. When the door is closed, the door frame 2 gradually approaches the sealing plate 13, and under the action of the spring 16, the sealing plate 13 and the door frame 2 come into tight contact, completing the seal.
[0054] To further optimize the design, sealing components are installed between the door frame 2 and both sides of the shielded room door opening. The sealing components include hollow sealing tubes 17, which are fixed between the two sides of the shielded room door opening and the side of the door frame 2.
[0055] The hollow sealing tube 17 is fixed between the two sides of the door opening of the shielded room and the side of the door frame 2. The elastic deformation of the hollow sealing tube 17 fills the gap between the door frame 2 and the door opening, thus playing a sealing role and preventing sound and electromagnetic wave leakage.
[0056] When the door is closed, the door frame 2 compresses the hollow sealing tube 17, causing the hollow sealing tube 17 to undergo elastic deformation, filling the gap between the door frame 2 and the door opening, thus achieving a seal. When the door is opened, the door frame 2 separates from the hollow sealing tube 17, and the hollow sealing tube 17 returns to its original shape.
[0057] The scheme is further optimized. The positioning module includes a positioning rod 18, which is horizontally fixed on the mounting bracket 5. The positioning rod 18 is set parallel to the bottom of the door frame 2. An elastic telescopic rod is installed at the end of the positioning rod 18. A positioning block is fixed on the track 1. The elastic telescopic rod and the positioning block are arranged correspondingly.
[0058] Positioning rod 18 is horizontally fixed on mounting bracket 5, and elastic telescopic rod is installed at the end of positioning rod 18. When door frame 2 moves to a specific position, elastic telescopic rod contacts positioning block on track 1, and elastic telescopic rod undergoes elastic deformation, which plays a buffering and positioning role, preventing door frame 2 from moving excessively.
[0059] When the door is opened or closed, the door frame 2 moves the mounting bracket 5, which in turn moves the positioning rod 18. When the positioning rod 18 moves to a specific position, the elastic telescopic rod contacts the positioning block, and the elastic telescopic rod is compressed to achieve buffering and positioning.
[0060] The design was further optimized so that the inner door panel 3 and the outer door panel 4 are made of galvanized metal sheet or stainless steel sheet, respectively.
[0061] The design was further optimized by installing handles 19 on the sides of the inner door panel 3 and the outer door panel 4 that are far apart from each other.
[0062] Further optimization of the design allows for the use of high-strength aluminum alloy for the mounting bracket 5 and support base 7. This material is lightweight and high-strength, ensuring the load-bearing capacity of the sliding components while reducing the overall weight of the door for easier operation. The pulley 6 can be made of nylon, which offers excellent wear resistance and self-lubrication, reducing friction with the track 1 and extending its service life.
[0063] The boom 9 can be made of stainless steel, which has high strength and corrosion resistance, ensuring the stability and reliability of the boom during long-term use. The support block 10 and slider 11 can be made of engineering plastics, such as polyoxymethylene (POM). This material has good self-lubricating and wear-resistant properties, which can reduce friction with the door frame 2.
[0064] The sealing plate 13 can be made of galvanized steel sheet, which has good corrosion resistance and strength, ensuring the sealing performance of the sealing plate 13. The connecting rod 14 can be made of stainless steel, and the spring 16 can be made of high-quality carbon steel wire, ensuring the elasticity and service life of the spring 16.
[0065] The hollow sealing tube 17 can be made of conductive rubber, which can connect with the door frame to form a complete shielding layer while ensuring a seal.
[0066] The inner door panel 3 and the outer door panel 4 are made of either galvanized metal sheet or stainless steel sheet. Galvanized metal sheet offers good corrosion resistance and cost-effectiveness, while stainless steel sheet provides higher strength and corrosion resistance. The choice can be made according to actual needs. The door frame 2 can be made of the same material as the door panels to ensure overall consistency and stability.
[0067] Track 1 can be made of high-strength steel with a galvanized surface to prevent rust. The width and height of track 1 can be designed according to the size of pulley 6, generally between 30mm and 50mm in width and 20mm and 30mm in height. The installation of track 1 should ensure horizontality and verticality to ensure smooth door movement.
