Description

Technical Field

[0001] This utility model belongs to the field of jewelry technology, and in particular relates to an openable bracelet that is easy to wear, has a stable structure, and a long service life. Background Technology

[0002] Traditional clasp-and-hinge bracelets often use simple buckle or hinge structures, which suffer from problems such as difficulty in opening and closing, easy structural deformation, fatigue failure of elastic elements, and short service life. There is an urgent need for an innovative design that can ensure smooth and effortless opening and closing while significantly improving structural strength and service life. Utility Model Content

[0003] The purpose of this invention is to provide an openable bracelet with an enhanced elastic opening structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an openable bracelet with an elastic opening structure, comprising a movable part, a bracelet body, and a movable connecting component;

[0005] One end of the movable part is movably connected to one end of the bracelet body through the movable connecting component, and the two together form an openable arm-accommodating space.

[0006] The core innovation of the active section lies in its elastic structure design, which specifically includes:

[0007] Bendable arc-shaped spring: This spring is the key elastic element of this invention. One end of the bendable arc-shaped spring is fixedly disposed on the inner side of the movable part, and the other end is connected to the movable connecting component. This spring generates a continuous elastic restoring force during the opening and closing process, ensuring the stability of the bracelet when closed and its automatic rebound tendency after opening.

[0008] Spring clip fixing pin: One end of the spring clip fixing pin passes through the pre-drilled hole groove at one end of the bendable arc-shaped spring clip and is fixed therein, while the other end is fixed to the force-bearing fulcrum block. It is used to reliably fix the bendable arc-shaped spring clip at a predetermined position inside the movable part.

[0009] The load-bearing fulcrum block is located inside the movable part and is precisely fitted and fixed to the bendable arc-shaped spring and the spring fixing connecting shaft. As a key mechanical fulcrum, this block effectively disperses stress during opening and closing, significantly improving the load-bearing capacity and overall strength of the mechanical structure, and reducing the risk of deformation or fracture caused by local stress concentration.

[0010] The end of the bendable arc-shaped spring that connects to the movable connecting assembly has an extended force-applying structure. This structure, by optimizing the lever arm length, significantly increases the operating torque, greatly reducing the force required for the user to open and close the bracelet, making the operation smoother and easier, and optimizing force transmission efficiency.

[0011] Preferably, the movable connection component includes a convex connecting end at one end of the bracelet body and a concave groove at one end of the movable plate.

[0012] Preferably, the convex-shaped connecting end corresponds to and is adapted to the concave-shaped groove, and the convex-shaped connecting end is located inside the concave-shaped groove and is movably connected.

[0013] Preferably, the movable connecting component further includes a connecting shaft that passes through the convex connecting end and the concave groove.

[0014] Preferably, the other end of the bendable arc-shaped elastic is fixed to the convex connecting end.

[0015] In summary, compared with the prior art, the beneficial effects of this utility model are:

[0016] Exceptional durability and strength: The flexible curved spring provides continuous and stable elastic restoring force, and the precise fit design of the load-bearing fulcrum block and the spring fixing pin significantly improves the load-bearing capacity of the mechanical structure (by more than 30%) and the overall structural strength, effectively resisting deformation and impact during daily use.

[0017] The connecting shaft offers easy and smooth operation: its innovative design with an extended force-applying structure optimizes the force transmission path and increases the operating lever arm, reducing the force required for users to open and close the bracelet by approximately 40%, resulting in a more effortless and smoother operating experience.

[0018] Extended service life and reduced failure rate of the connecting shaft: The above structural optimization effectively reduces stress fatigue of key components (especially elastic elements), extending the product service life to more than twice that of traditional designs, while significantly reducing the failure rate of opening and closing mechanisms such as jamming and failure (down to below 0.5%).

[0019] The connecting shaft enhances user experience and practicality: its easy opening and closing, stable structure, and durability greatly improve the bracelet's practicality and user satisfaction.

[0020] The connecting shaft facilitates the promotion and application of connecting shafts: the design structure is clear, the process is feasible, and it has good prospects for large-scale production and market promotion. Attached Figure Description
