Patent ID: 11255372

Abstract:
An anti-theft suction cup structure includes a suction-cup body and a pressure ring. The suction-cup body has a suction end and a braking end. The suction end has a cup groove recessed on a side thereof toward the braking end, the braking end has an exhaust part formed thereon and is normally in a closed status. The pressure ring is mounted on an outer periphery of the suction-cup body. When the suction end is used for suction, air in the cup groove is extracted to form vacuum between the cup groove and the attached object, the sidewall of the cup groove is tightly attached with the attached object. When air is injected into between the cup groove and the attached object, non-vacuum is formed between the cup groove and the attached object. In vacuum, the pressure ring is configured to press hard on the suction-cup body.
