Passive retractable shield door

Abstract

This invention provides a passive telescopic shielding door, comprising: a guide rail assembly, a drive assembly, and a telescopic unit, wherein the telescopic unit is slidably connected to the guide rail assembly; the telescopic unit includes two active doors and two passive doors located between the two active doors; the guide rail assembly includes at least one first guide rail and one second guide rail, the first and second guide rails being on the same horizontal plane and arranged parallel to each other, the active doors and passive doors being slidably connected to the first and second guide rails respectively; each active door is correspondingly provided with the drive assembly, the drive assembly being used to drive the active door to move back and forth along the first guide rail. This invention achieves the effect of one drive assembly driving multiple shielding doors by adding passive doors at intervals between the active doors and using different guide rail mounting methods, thereby reducing the number of drive assemblies and saving costs.
