This utility model relates to the field of anti-backflow terminal control technology, and discloses a multi-port anti-backflow intelligent control terminal, including a multi-port anti-backflow control device. A fixed outer shell is provided on the outside of the multi-port anti-backflow control device for fixing the device. A first protective mechanism is provided on the outside of the fixed outer shell for protecting the device. A connecting component is provided on one side of the first protective mechanism for sealing the device to the fixed outer shell. When the top plate is impacted, the fork-shaped hinge frame causes the sliding block to slide away from the fixed block.
