The invention belongs to the field of home design and particularly relates to an automatic rotary return guardrail. The automatic rotary return guardrail comprises a fixing frame and an isolation rail, and the isolation rail comprises an upper crossbar, a lower crossbar and a plurality of vertical bars arranged between the upper crossbar and the lower crossbar. When the guardrail is needed, the door isolation rail is lifted upwards, the lower crossbar is enabled to be higher than a slope side embankment, then the isolation rail is rotated, only the isolation rail needs to be loosened when a doorway is closed, the isolation rail moves downward in gravity center under the action of own gravity and slowly drops down along the slope side embankment while rotating to return, and a user cannot forget to close the doorway due to negligence. The automatic rotary return guardrail has the advantages of good rotary return effect, simple structure, convenience in operation, economical cost, more safety in use and long service life.
