The document with application number 201320724678.5 discloses a bidirectional double-opening soft door for a shielding tent, which is provided with an inner shielding door and an outer shielding door, although the leakage of electromagnetic waves is prevented to a certain extent, the arrangement of a single double-layer door is complicated, and the purpose that people can quickly get in and out can not be achieved by the adjacent double-layer door, but the electromagnetic waves are possibly emitted to a greater extent due to the increase of the operation time.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model discloses the technical problem who plans to solve provides an electromagnetic shield door.
the technical scheme of the utility model for solving the technical problems is to provide an electromagnetic shielding door, which comprises a tent body, a door body and an overlap shielding layer; one end of the lapping shielding layer is connected with one end of the tent body in a sealing way; the shielding door is characterized by also comprising a permanent magnet and foamed cotton; foaming cotton is filled in the peripheral edge of the door body; the permanent magnets are uniformly arranged at the edge part of the other end of the lapping shielding layer and the edge part of the other end of the tent body, and the permanent magnets on the lapping shielding layer and the permanent magnets of the tent body are mutually matched and connected through magnetic force; the foam cotton is filled between the lapping shielding layer and the tent body and is attached to the sealing connection part of the lapping shielding layer and the tent body; the inner side and the outer side of the door body are respectively contacted with the permanent magnet on the lapping shielding layer and the permanent magnet on the tent body, and the door body is fixed between the lapping shielding layer and the tent body through the mutual magnetic force between the permanent magnet on the lapping shielding layer and the permanent magnet on the tent body.
compared with the prior art, the utility model discloses beneficial effect lies in:
(1) This shield door adopts the mode that the foaming cotton combines together with the permanent magnet, when providing excellent shielding performance, realizes the swift discrepancy of inside and outside personnel of tent. When the tent is closed, the information leakage can be reduced by triple sealing of the permanent magnet between the door body and the tent body, the foamed cotton and the permanent magnet between the door body and the lapping shielding layer.
(2) The foaming cotton is filled in the peripheral edge of the door body, and the foaming cotton is filled between the lapping shielding layer and the tent body so as to ensure good sealing effect. The foamed cotton is filled in the edge of the door body, so that the overall shielding effect of the tent is not influenced.
(3) The door body is clamped between the lap-joint shielding layer and the tent body through the mutual magnetic force between the permanent magnet on the lap-joint shielding layer and the permanent magnet on the tent body, so that airtight fitting is realized, and a good electromagnetic shielding effect is ensured.
