DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0017] like Figure 1-4As shown, a marine A60 grade aluminum electromagnetic shielding door, the structure of which includes a door leaf 1 and a door frame 2 rotatably connected by a hinge mechanism 3, a handle 16 and a locking mechanism 7 are installed on the door leaf 1, a conductive seat and a jumper wire 8 are also connected between the door leaf 1 and the door frame 2, the edge of the door leaf 1 near the door frame 2 is a profile frame, the profile frame is provided with a first protrusion, a second protrusion and a third protrusion with gradually increasing heights from the outside to the inside, the inside of the third protrusion is the profile frame body, the inner outer end of the inner side of the profile frame body is filled with an A fireproof strip 12, and the space between the third protrusion and the profile frame body is filled with a B fireproof strip 1 3. The main body of the profile frame is filled with a filler 15. The door frame 2 includes a door frame profile and a stainless steel plate 18 wrapped around the outside of the door frame profile. The door frame profile is provided with a first convex strip, a second convex strip and a third convex strip with gradually increasing heights from the outside to the inside. A conductive rubber strip 14 is filled between the first convex strip and the second convex strip. A pair of spring leaves 6 are relatively installed between the second convex strip and the third convex strip through a cross countersunk screw 4 and a pressure plate 5. When the door leaf 1 and the door frame 2 are closed, the end of the first convex strip squeezes the fireproof strip B 13, the end of the third convex strip squeezes the conductive rubber strip 14, and the end of the second convex strip is stuck between the pair of spring leaves 6.

[0018] In the above structure, the fireproof strip is arranged in the inner door leaf groove and has good expansion properties. The conductive rubber strip 14 is installed in the groove of the door frame. The door frame profile and the profile frame of the door leaf are aluminum parts with nickel-phosphorus plating on the surface, forming a conductor with the conductive rubber strip 14 and the reed 6, and having continuous conductive and magnetic properties.

While reducing the overall weight of the door frame 2, it can also solve the electrochemical corrosion problem of the direct contact between the steel wall and the aluminum door frame. The door frame is designed to be on the back side to solve the fire resistance problem. During installation, the bolts should be fixed from the inside and not exposed to the outside, which can solve the problem of bolt holes intersecting and shielding weakness.
