Description
Technical Field
The utility model mainly relates to an electromagnetic shield door field especially relates to a radiation protection electromagnetic shield door.
Background
Electromagnetic shielding is an important component of electromagnetic compatibility technology and is the most effective means for suppressing radiation interference. When a cabinet, a shielding room, a communication shelter and a microwave dark room are built, a shielding door is a main path of electromagnetic leakage and is a main factor for determining the good and bad shielding performance. Factors affecting the shielding effectiveness of the electromagnetic shielding door are: the material of the door section bar, the selection of the door section bar plating layer, the connection mode of the door frame and the shielding chamber, the door seam sealing gasket, the connection mode of the conductive gasket and the section bar and the layer number of the conductive gasket. Theories and practices prove that the shielding effectiveness of a gap between a door plate and a door frame of the shielding door is a key factor influencing the shielding performance of the shielding door.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect of prior art, the utility model provides a radiation protection electromagnetic shield door, including shield door body 1, shield door body 1 is whole to be made by the copper tungsten alloy, 1 edge of shield door body is equipped with radiation protection conductive rubber 2, 1 rear end of shield door body is equipped with bracing piece 3, be equipped with extension spring 4 between bracing piece 3 and the shield door body 1.
Preferably, hooks are arranged at two ends of the extension spring 4.
Preferably, the supporting rod 3 and the top of the shielding door body 1 are provided with fixing blocks 5.
Preferably, a rotating shaft 6 is arranged on one side of the shielding door body 1.
The utility model has the advantages that: the processing and forming are simple, and the radiation-proof performance is good.
