Problems solved by technology
[0002] Existing electromagnetic shielding doors only have two opening methods: flat opening and sliding. The above two opening methods have the following limitations: the height and span of the door body are small, and the parallel tracks used in the sliding type take up a lot of space, which is difficult for electromagnetic shielding. The space size of the room has certain requirements
