Modèle 3D de fermoir de boîte ouverte

An open box clasp is a widely used jewelry fastening mechanism known for its secure locking and ease of use. It is commonly found on bracelets, necklaces, and other fine jewelry items. This type of clasp consists of two main components: The Box (Housing) – A hollow rectangular or cylindrical unit with an open slot. The Inserted Tab (Tongue) – A flexible metal tab that slides into the box and locks in place. The mechanism works as follows: The tongue is slightly arched or bent, allowing it to compress when pushed into the box. Once inside, the tongue snaps upward into a notch or catch, securing the clasp. To release, a small lever or pressure point is used to gently compress the tongue again, allowing it to slide out. Open box clasps are appreciated for their: Streamlined appearance that blends well with the design of the jewelry Secure hold that prevents accidental opening User-friendly operation, even with one hand They can be designed with single or double locking tongues for added security, and are often used in high-end or vintage jewelry pieces. Custom versions can be made in various materials such as gold, silver, platinum, or stainless steel, and in multiple sizes to suit different styles and weights of jewelry.
