Passive telescopic shielding door with single guide rail

The invention provides a single-guide-rail passive telescopic shielding door which comprises a first guide rail, a driving assembly and a plurality of telescopic units, the telescopic units are slidably connected to the first guide rail, and the driving assembly is fixedly connected to the first guide rail; the telescopic unit comprises two driving doors which are transversely and linearly distributed and two driven doors located between the two driving doors, the driving doors are slidably connected to the first guide rails, the driven doors are slidably connected to the driving doors, the driving doors are correspondingly provided with the driving assemblies, and the driven doors are slidably connected to the driving doors. The driving assembly is used for driving the driving door to move face to face or back to back along the first guide rail and synchronously driving the driven door to move. The driving door carries the driven door, the effect that one driving assembly drives the multiple shielding doors
