Electromagnetic shielding double door

Abstract

The invention discloses an electromagnetic shielding double door. The electromagnetic shielding double door comprises a door frame, a left door plate, a right door plate, shielding reeds and metal shielding sealing strips, notches are formed in the eccentric positions of the top and the bottom of the door frame, door frame compensation blocks are additionally arranged, and the shielding reeds areinstalled on the surfaces of the door frame compensation blocks and used for pressing the metal shielding sealing strips; and door plate compensation blocks matched with the door frame compensation blocks are additionally arranged at the top and the bottom of the left door plate, when the double door is in a closed state, the door plate compensation blocks are embedded into the door frame compensation blocks to be meshed and clamp the shielding reeds and the metal shielding sealing strips, and electromagnetic shielding of the double door is achieved. According to the electromagnetic shieldingdouble door, the door frame compensation blocks and the door plate compensation blocks are additionally arranged at the door frame and the door plate respectively, so that the problem of height difference at the compensation blocks is solved, the structure and the mounting mode of the shielding sealing strips are optimized, the electrical continuity of the double door is realized, the shielding performance is improved, and technical support is provided for a shelter with the 40dB double door.

Description

technical field [0001] The invention belongs to the technical field of shielded double doors, in particular to an electromagnetic shielded double door. Background technique [0002] In recent years, with the continuous acceleration of the informatization process, electromagnetic countermeasures have become one of the key factors that determine the outcome of a war. As a common carrier of military equipment and personnel work and life, the shelter has become one of the important indicators for testing the performance of the shelter. As the largest opening of the shelter, the electromagnetic shielding performance of the door directly affects the overall shielding performance of the shelter. At the same time, with the diversification of modern equipment, large equipment such as cabinets and transportation equipment have continuously increased the requirements for the passage size of the other hatch door, and the development of shielded double doors is imminent.

AI Technical Summary

Problems solved by technology

[0003] However, it is difficult to vigorously develop and promote shielded double-leaf doors mainly due to the following problems: 1. There is a large gap between the door seam and the door frame contact of the double-leaf door; 2. There is a large gap between the upper and lower corners of the two doors and the door frame contact. ;3. The shielding sealing strip between the two door panels is disconnected, making it difficult to fully contact
