AI Technical Summary
Technical Problem
Existing three-wing revolving doors cannot achieve radial expansion and contraction of the door panels, resulting in a fixed gap between the door panels and the fixed curved wall outside the revolving door, which poses a safety hazard of trapping people.
Method used
The top rotating frame is driven by a drive motor. Combined with electric push rods, springs and electromagnets, the movable door leaf can be extended and retracted. The electromagnet is de-energized by a contact strip switch, and the spring pushes the door leaf back to widen the gap between the door and the door to prevent people from being trapped.
Benefits of technology
This has improved the safety of revolving doors, avoiding the risk of pedestrians being pinched and enhancing their overall security.

Abstract
The utility model relates to a kind of three-wing telescopic door structure, belong to the technical field of revolving door, including fixed frame assembly, top rotating frame is rotationally arranged on fixed frame assembly, and top rotating frame is supported on fixed frame assembly by roller;Top rotating frame is equipped with electric push rod, spring and electromagnet assembly, electric push rod pushes movable door leaf to extend relative to fixed door leaf, and is attracted by electromagnet assembly after spring is compressed;Spring pushes movable door leaf to extend and retract relative to fixed door leaf after electromagnet assembly is unlocked;When pedestrian is clamped between the outer frame of movable door leaf and door column, electromagnet assembly is de-energized by triggering the contact strip switch on door column, spring makes movable door leaf retract quickly to the center direction of revolving door, expand the gap between door gap, so as not to clamp person, realize the intrinsic safety of revolving door entrance, improve the safety of revolving door.
