5. The charging head dragging-preventing structure for the charging pile according to claim 1, wherein a limiting ring (10) is installed on the charging wire (9), and the diameter of the limiting ring (10) is larger than the aperture of the through hole (12).
6. The charging head dragging-prevention structure for the charging pile according to claim 1, wherein a rod hole is formed in the hanging block (6), the rod hole is in clearance fit with the pull rod (23), and an anti-skid soft rubber pad is adhered to the inner side of the clamping plate (20).
7. The charging pile charging head dragging prevention structure according to claim 1, which is characterized in that the charging head dragging prevention structure comprises the following specific working steps:
the method comprises the following steps: a user holds the pulling block (24) with a hand and moves outwards, the sleeve spring (22) is stressed to contract, the clamping plate (20) moves into the movable cavity (21), the clamping plate (20) is not attached to the charging head (7), and after the charging head (7) is taken down from the hanging block (6), the user charges the charging head (7) and external charging equipment;
step two: when the charging pile main body (2) is used, a user forgets to pull the charging head (7) out of the charging equipment, the charging head (7) is dragged when the charging equipment leaves, a clockwork spring (14) in the accommodating cavity (16) is stressed to twist, the winding ring (13) rotates clockwise around the shaft center rod (15), the charging wire (9) in the accommodating cavity (16) is continuously pulled outwards until the charging wire (9) on the winding ring (13) is pulled completely, the charging wire (9) with the anti-dragging ring (19) is also pulled outwards at the moment, because the diameter of the anti-dragging ring (19) is equal to that of the clamping ring hoop (17), when the anti-dragging ring (19) touches the clamping ring hoop (17), two alarm buttons (18) on the anti-dragging ring (19) are touched and opened, a circuit between the power supply and the alarm (5) is communicated, and the alarm sound is generated when the alarm (5) is electrified, the user can know that the charging head (7) is dragged in time;
step three: after knowing that the charging head (7) is dragged, the user pulls the charging head (7) out of the charging equipment in time, moves the pulling block (24) outwards again, moves the clamping plate (20) into the movable cavity (21) again, the charging head (7) is inserted into the hanging block (6), the user loosens the pulling block (24), under the elastic action of the sleeve spring (22), the clamping plate (20) returns to the original position, the clamping plate (20) is attached to the charging head (7) again, meanwhile, the clockwork spring (14) is not stressed any more, the winding ring (13) rotates anticlockwise around the axle center rod (15), the charging wire (9) enters the accommodating cavity (16) and is wound on the winding ring (13), meanwhile, a charging wire (9) with a drag-prevention ring (19) is far away from the wire clamping hoop (17), an alarm button (18) is turned off, and the alarm (5) is turned off to stop working.
