Anti-theft nut structure
The introduction of anti-theft nuts has brought significant benefits to public infrastructure and the safety of personal belongings. Today, these innovative fasteners are widely adopted across various industries due to their effectiveness in preventing unauthorized removal.
The primary objective of this invention is to create a secure coupling mechanism that connects components without any wobbling or looseness. A key feature involves a resin plate equipped with a locking receiving portion that contains a locking hole. On the edge of a door or panel, a locking arm is designed with a locking claw. This claw can be inserted into the locking hole and securely fixed in place.
To enhance the locking mechanism, a crush wall is positioned on the opposite side of the locking claw. When the locking arm is inserted into the hole, both the claw and the crush wall work together to expand the locking hole slightly. During insertion, the crush wall exerts pressure against the inner wall of the hole. Once fully engaged, the crush wall forms a stable, interlocked structure by biting into the inner surface of the locking hole. This ensures that the resin-molded parts remain firmly connected without any movement or vibration.
In addition, a general-purpose fastening screw has been developed for use in a wide range of applications. The screw features a tapered tail, an axial groove along its shaft, and serrated threads on the grooved section. It also includes a screwdriver slot for easy installation and removal. This design allows for smooth driving into materials while maintaining a strong grip, preventing the screw from loosening or backing out under vibration or impact. The result is a reliable fastening solution that enhances durability and performance in both industrial and everyday settings.
