The invention relates to the technical field of doors, in particular to a roller blind type rapid door. The roller blind type rapid door comprises a door curtain, the upper end of the door curtain is fixed to a roller, and rails are arranged on the left side and the right side of the door curtain. The rails comprise fixing connecting plates, front rail outer plates and rear rail outer plates. The front rail outer plates are provided with front arc arch buffering parts, and the rear rail outer plates are provided with rear arc arch buffering parts. Guiding sections for guiding the door curtain are formed in the front-and-back gaps of the front rail outer plates and the rear rail outer plates. The guiding sections are internally provided with front direct guiding function rubber plates and rear direct guiding function rubber plates. The door curtain is made of flexible materials and provided with strengthening protection strips. Guiding devices are arranged at the left ends and the right ends of the strengthening protection strips. The roller blind type rapid door is firm and stable in structure, not prone to damage, good in pressure resistance, long in service life and low in noise.
