Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding door technology, and in particular to the sealing structure of a magnetic electromagnetic shielding door. Background Technology

[0002] Electromagnetic shielding doors are special protective doors used to isolate electromagnetic interference. They form a continuous electromagnetic shield through conductive materials and special structural design, which can effectively block the propagation of electromagnetic waves within a specific frequency range. Their core functions include electromagnetic isolation and physical protection: on the one hand, attenuating external electromagnetic interference to prevent interference with sensitive internal equipment; on the other hand, preventing the leakage of internal electromagnetic information while maintaining the airtightness of the space.

[0003] Traditional electromagnetic shielding doors rely on a single sealing structure, which is prone to micro-gap formation due to uneven pressure, material deformation, or assembly errors when closed, leading to electromagnetic wave leakage and a reduction in shielding performance. In view of this, this application proposes a magnetic suction electromagnetic shielding door sealing structure based on the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a magnetic electromagnetic shielding door sealing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic electromagnetic shielding door sealing structure includes a door leaf and a door frame. A first wall is provided on one side of the door frame, and a hinge is fixedly installed on one side of the door leaf. One end of the hinge is connected to a second wall. An inner liner is fixedly installed on the inner side of the door leaf. The inner liner is located inside the door frame. A first sealing gasket is fixedly installed in the gap area formed by the inner liner and the door leaf. A second sealing gasket is fixedly installed on the side of the door frame near the door leaf. When the door leaf is closed, the surfaces of the first sealing gasket and the second sealing gasket are in contact.

[0007] Furthermore, a protrusion is fixedly installed on the side of the first sealing gasket near the second sealing gasket, and a groove is provided on the side of the second sealing gasket near the first sealing gasket. When the door is closed, the protrusion of the first sealing gasket is embedded in the groove of the second sealing gasket to form an interference fit.

[0008] Furthermore, the door frame includes two horizontal beams and two vertical beams. The horizontal beams are T-shaped and include a vertically arranged web and a horizontally extending wing plate. The vertical beams are inserted between the two horizontal beams. An extension plate is fixedly installed on one side of the vertical beams, and the second sealing gasket is fixedly installed between the extension plate and the wing plate.

[0009] Furthermore, a first fixing screw is provided between the crossbeam and the first wall, a second fixing screw is provided between the vertical beam and the crossbeam, and a sealing block is fixedly installed on the side of the web plate near the vertical beam, the sealing block being located in the groove of the vertical beam.

[0010] Furthermore, a handle is fixedly installed on one side of the door leaf, and an installation plate is fixedly installed on one side of the door leaf. A permanent magnet is fixedly installed on one side of one of the vertical beams, and a magnetically conductive metal sheet is fixedly installed on the side of the installation plate near the permanent magnet.

[0011] Furthermore, two symmetrical connecting blocks are fixedly installed on one side of the second wall, and a rotating shaft is rotatably installed between the connecting blocks. A connecting sleeve is fixedly installed at one end of the hinge, and the connecting sleeve is fixedly installed outside the rotating shaft.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a first sealing gasket, a second sealing gasket, and an inner liner, ensures that when the door is closed, the first sealing gasket on the inside of the door is tightly fitted with the second sealing gasket on the door frame. The stability of the inner liner ensures that the first sealing gasket and the second sealing gasket are tightly fitted and maintain uniform contact pressure. This tight-fitting design effectively prevents electromagnetic waves from leaking from the door gaps and ensures the performance of the electromagnetic shielding door.

[0014] 2. By setting up protrusions and grooves, when the door is closed, the protrusions are embedded in the grooves to form an interference fit. This double sealing structure eliminates gaps through physical compression, effectively blocking the electromagnetic wave leakage path and improving shielding effectiveness.

[0015] 3. This utility model, by setting up horizontal beams, vertical beams, and sealing blocks, forms a high-strength frame by splicing horizontal and vertical beams. When installing the door frame, the lower horizontal beam is first fixed to the first wall, and then the two vertical beams are fixed together with the lower horizontal beam using second fixing screws. Finally, the upper horizontal beam is fixedly installed on the top of the horizontal beam. At this time, the sealing block is also installed in the groove of the vertical beam, which further improves the sealing performance at the connection between the horizontal and vertical beams. At the same time, the sealing block filling the groove of the vertical beam can also enhance its structural stability. Attached Figure Description

[0025] When door 1 is closed, the first sealing gasket 7 on the inside of door 1 is tightly fitted with the second sealing gasket 8 on the door frame 2. The stability of the lining 6 ensures that the first sealing gasket 7 and the second sealing gasket 8 are tightly fitted, maintaining uniform contact pressure. This tight fit design effectively prevents electromagnetic waves from leaking from the door gap, ensuring the performance of the electromagnetic shielding door.
