Description

Technical Field

[0001] This utility model relates to the field of watch accessory technology, and in particular to a watch strap and watch case connection structure. Background Technology

[0002] The watch case, as the "main framework" of a watch, is primarily used to house and protect core components such as the dial and movement. Its materials are mostly metals, such as stainless steel, titanium alloy, ceramic, and plastic. Its shape and size need to be adapted to the dial. At the same time, the outer surface is usually designed with connection points for cooperating with the watch strap. The watch strap is the key component for wearing the watch. One end is connected to the watch case, and the other end is wrapped around the wrist for fixation. Materials include leather, metal links, rubber, nylon, etc., and there are various styles to meet different wearing scenarios and aesthetic needs.

[0003] The watch strap and case are two core components of a watch. They are combined through a specific connection structure to ensure the watch's wearing function and overall performance. In the design and use of watch products, the connection structure between the watch strap and case is a key part that affects the product's practicality, stability, and lifespan.

[0004] While existing watch strap and case connection structures achieve the connection between the watch strap and the case, some structures use fixed welding or a single buckle connection. Although these achieve basic connection functions, fixed welding prevents the watch strap from being disassembled and replaced, making it difficult to meet users' personalized needs for watch strap style and material. Single buckle connections, due to concentrated stress, are prone to loosening and falling off after long-term use, affecting connection stability and even causing the watch to fall and be damaged. Other structures, although supporting disassembly and assembly, lack precise positioning and limiting designs, which can easily lead to positional misalignment during assembly, resulting in uneven connections. This not only affects aesthetics but also accelerates component wear. In addition, most connection structures lack protective components, making the connection point susceptible to impacts during daily wear, shortening its lifespan. Furthermore, the uneven stress distribution of traditional connection structures can easily cause deformation of the watch case or watch strap connection end due to excessive local stress after long-term wear, further reducing connection reliability. Therefore, a new watch strap and case connection structure is proposed to solve the above problems. Utility Model Content

The movable engagement of the assembly insert 38 and the assembly slot 33 ensures both firmness and ease of connection. After the initial connection is completed and the lock sleeve 42 of the protective locking component 4 is pushed, so that its inner wall fits against the outer surface of the connecting seat 31. The tenon structure locking block 43 on the inner wall of the lock sleeve 42 is embedded into the tenon structure locking groove 32 on the outer surface of the connecting seat 31, so as to achieve a tight connection between the lock sleeve 42 and the connecting seat 31. Then, the telescopic locking pin 41 on the upper surface of the connecting seat 31 is operated so that its telescopic end is locked into the lock hole of the outer lock hole plate 44 of the lock sleeve 42, thus completing the secondary locking and further enhancing the connection stability. At the same time, the connecting guard plate 45 on the inner side of the lock sleeve 42 reduces weight and improves aesthetics through the decorative hole 46. The anti-collision strips 47 on its upper and lower surfaces can buffer and protect during collisions, while the connecting guard plate 45 itself forms a shield and protection for the connection part.

[0037] During disassembly, first release the telescopic locking pin 41 from the lock hole plate 44, remove the lock sleeve 42, and then rotate the positioning plate 37 to disengage the assembly insert 38 from the assembly slot 33, thus separating the watch strap 2 from the watch case 1. The entire process takes into account the connection firmness, the convenience of disassembly and assembly, and the structural protection.
