AI Technical Summary

Technical Problem

The existing shielded room's blade design has problems such as inconvenience in entering and exiting, difficulty in operation, safety hazards, and poor electromagnetic wave isolation effect.

Method used

The door adopts a downward lifting blade structure, which combines beryllium copper springs with bladeless door sill seats and a transmission linkage mechanism to achieve a tight connection between the shielding door and the door frame on the same plane. The lifting action of the beryllium copper springs is driven by electric or manual means to achieve electromagnetic wave isolation.

Benefits of technology

It provides convenient access and ensures a tight fit between the shielded door and the door frame, achieving complete electromagnetic wave isolation and solving the problems of space waste and difficult operation of traditional shielded doors.

Abstract

This utility model provides a shielding door structure with a downward-pressing lifting blade, comprising a shielding chamber, an entrance to which is equipped with two door frames, and a shielding door between the two door frames. Each of the two door frames has two outer blades, and the shielding door has an inner blade on each of its left and right sides. A fixed gap exists between the apexes of two adjacent outer blades, allowing one of the inner blades to be tightly inserted to achieve shielding, and they can be combined to form a blade group. A connecting rod is installed inside the shielding door, and a guide rail seat is installed inside the bottom of the shielding door. A lifting blade is installed at the bottom of the shielding door, and the connecting rod can drive the lifting blade to move downwards along the guide rail seat. Two beryllium copper springs are installed at the bottom of the lifting blade, and a bladeless threshold seat is installed below the lifting blade. The two beryllium copper springs can engage with the bladeless threshold seat to achieve electromagnetic wave isolation.
