They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Please see Figure 1-7This utility model provides a technical solution: an electromagnetically shielded special door, including a load-bearing lower threshold 1, a door frame 2 fixedly connected to the upper end of the load-bearing lower threshold 1, two door leaves 4 provided on the front side of the door frame 2, multiple hinges 3 provided on the front side of the door frame 2, the two movable ends of the multiple hinges 3 being fixed to the door frame 2 and the two door leaves 4 respectively, a door leaf limiting component, the door leaf limiting component being disposed inside the door frame 2, an electromagnetic shielding component, the electromagnetic shielding component being disposed on the door frame 2, the electromagnetic shielding component including an electromagnetic shielding strip 5, the electromagnetic shielding strip 5 being fixedly connected to the upper end and both sides of the door frame 2, electromagnetically shielded beryllium copper spring sheets 15 being riveted around the door frame 2, and Monel silk sealing strips 16 being fixedly connected to the upper and lower sides of the two door leaves 4 and the corresponding side close to the door frame 2, and the door leaves 4 having insert-type folded edges around their perimeter.

[0031] The door leaf limiting assembly includes a blade-type mechanical combination lock 6, which is fixedly installed inside the left door leaf 4. A connecting shaft 8 is rotatably connected inside the blade-type mechanical combination lock 6. The connecting shaft 8 extends out of the blade-type mechanical combination lock 6 and is fixedly connected to a handle 7. A gear 9 is fixedly connected to the surface of the connecting shaft 8. A U-shaped frame 10 is slidably connected inside the blade-type mechanical combination lock 6. A slide groove 12 is opened on the surface of the blade-type mechanical combination lock 6. A locking block 11 is slidably connected to the inner wall of the slide groove 12. The locking block 11 is fixedly connected to the U-shaped frame 10. A fixing plate 13 is fixedly connected to the surface of the right door leaf 4. A limiting frame 14 is fixedly connected to the front side of the fixing plate 13. The locking block 11 is engaged with the limiting frame 14.

[0032] The number of the card block 11, the slide 12, the fixing plate 13, and the limit bracket 14 are all arranged in two sets in a linear array on the surface of the door leaf 4.

[0033] The interiors of both door panels 4 are filled with graphite conductive cotton and aluminum honeycomb.

[0034] Multiple hook-shaped fixing hooks 17 are fixedly connected around the door frame 2.

[0035] The lower end of the load-bearing lower sill 1 is U-shaped.

[0036] When using this device, when the door leaf 4 is closed, the blade-type folded edges around the door leaf 4 are inserted into the gap of the electromagnetic shielding beryllium copper spring sheet 15 to form the first electromagnetic seal; at the same time, the Monel silk sealing strip 16 forms the second electromagnetic seal after the door leaf 4 is closed and pressed, ensuring that there are no less than two electromagnetic seals at all overlapping joints of the door body.

[0037] The electromagnetic shielding strip 5 and the electromagnetic shielding beryllium copper spring sheet 15 work together to achieve electromagnetic shielding between the door frame 2 and the door leaf 4, preventing the electromagnetic energy of the external environment from radiating to the internal equipment, and also shielding the leakage of electromagnetic energy generated by the internal equipment to the external environment.

[0038] By operating the blade-type mechanical combination lock 6, the handle 7 is turned to drive the connecting shaft 8 to rotate, which in turn drives the gear 9 to rotate. The rotation of the gear 9 drives the U-shaped frame 10 to slide inside the blade-type mechanical combination lock 6, and at the same time drives the locking block 11 to slide in the slide groove 12. When the locking block 11 slides to the position corresponding to the limit frame 14, the locking block 11 engages with the limit frame 14, thereby limiting and locking the door leaf 4.

[0039] When unlocking, the blade-type mechanical combination lock 6 is unlocked by operating it in reverse, so that the card block 11 is separated from the limit frame 14, and the door leaf 4 can be opened.

[0040] The load-bearing lower threshold 1 is welded from special steel and has a "U"-shaped design at the bottom, which increases the stability and load-bearing capacity of the door. The door frame 2 is fixedly connected to the load-bearing lower threshold 1, which further enhances the structural strength of the entire door.

[0041] Door frame 2 is welded to the shielding room. After it is secure, an electromagnetic shielding strip is used to cover the gap between the outdoor door frame 2 and the steel column of the shielding room. The gap on the indoor side is filled with graphite conductive adhesive.

[0042] The design of multiple electromagnetic shielding structures effectively shields electromagnetic energy, ensuring the electromagnetic environment safety of places such as cabinets and shielded rooms.

[0043] The robust design of the load-bearing lower threshold and door frame, along with the precise fit of the door leaf limiting components, ensures the stability and reliability of the door.

[0044] The design of the leaf-type mechanical combination lock 6 makes the opening and closing of the door leaf 4 simple and quick, improving efficiency.

[0045] This electromagnetic shielding special door is suitable for various places that need to prevent electromagnetic leakage, and has high practical value and promising prospects for promotion.

[0046] The installation of fixing hooks 17 around the door leaf 4 facilitates the strengthening of the connection between the door frame 2 and the shielding chamber, thereby enhancing the stability of the door frame 2.

[0047] Furthermore, by installing electromagnetic shielding strips 5, electromagnetic shielding beryllium copper spring sheets 15, and Monel wire sealing strips 16 on the surfaces of door leaf 4 and door frame 2, and welding door frame 2 to the shielding room, and then covering the gap between the outer side door frame 2 and the steel column of the shielding room with electromagnetic shielding strips, and filling the gap on the inner side with graphite conductive adhesive, the design of multiple electromagnetic shielding structures effectively shields electromagnetic energy, ensuring the electromagnetic environment safety of places such as cabinets and shielding rooms.
