Abstract

The invention relates to a high-performance double-layer flexible magnetic shielding door which comprises a door frame, a double-layer flexible door sash assembly connected with the door frame through a double-hinging hinge and a four-point synchronous locking mechanism arranged on the double-layer flexible door sash assembly. The high-performance double-layer flexible magnetic shielding door is suitable for a channel for devices and persons to go in or out on a magnetic shielding room protected by a zero frequency low-intensity magnetic field, the continuity of the shieldinglayer magnetic circuit of the magnetic shielding room and the magnetic properties of a high magnetic conductive material can be ensured after the high-performance double-layer flexible magnetic shielding door is closed, meanwhile the door has a very low residual magnetic field, is installed on the magnetic shielding room in a 50000 nT zero frequency low-intensity magnetic field and ensures that the whole magnetic shielding room has very high magnetic shielding effectiveness, and an indoor magnetic shield can be below 100 nT.

Description

technical field [0001] The invention relates to a high-performance double-layer flexible magnetic shield door. Background technique [0002] For the magnetic shielding door installed in the magnetic shielding room with an internal magnetic field strength of nT level, it generally works in the earth's weak magnetic environment with a magnetic field strength of about 50000nT. However, the traditional electromagnetic shielding doors on the market have very poor shielding effect on zero-frequency weak magnetic fields, and cannot meet the index requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of magnetic shielding door for a zero-frequency weak magnetic field shielding room. [0004] Technical scheme of the present invention is: [0005] A high-performance double-layer flexible magnetic shielded door comprises a door frame, a double-layer flexible door leaf assembly connected to the door fram...
