Description

Technical Field

[0001] This utility model relates to the field of silicone watch straps, specifically a detachable silicone watch strap. Background Technology

[0002] With the widespread adoption of smart wearable devices and traditional watches, the comfort, durability, and detachability of watch straps, as components that come into direct contact with the human body, have become key concerns for users. Silicone watch straps, due to their softness, skin-friendliness, sweat and corrosion resistance, and ease of cleaning, are widely used in various types of watches. However, existing silicone watch straps typically use traditional spring bars or simple buckle designs to connect to the watch body, which presents the following technical problems:

[0003] Inconvenient disassembly: Traditional spring bar connections require tools to press the spring bar, which demands a high level of user skill, and can easily damage the watch body or strap, especially when changing the strap; although the simple buckle structure does not require tools, the buckle strength is insufficient and it is easy to loosen and fall off after long-term use.

[0004] Insufficient connection stability: Traditional connection structures only achieve fixation through single-point snap-fit ​​(such as the fit between a circular protrusion and a groove). When subjected to lateral force, the watch strap is prone to shifting or falling off, and its reliability is poor, especially in the case of vigorous sports. To address this, we have proposed a detachable silicone watch strap. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a detachable silicone watch strap, which solves the aforementioned problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a detachable silicone watch strap, including a watch body, on both sides of the watch body are detachable silicone watch straps, the silicone watch straps are provided with multiple sets of fixing holes at equal intervals, and another silicone watch strap is fixedly installed at one end, the insert locking pin being used to insert into the fixing hole at the corresponding position.

[0007] Preferably, the side of the watch body is provided with a circular groove and a rectangular groove, the rectangular groove and the circular groove are connected and penetrate the side of the watch body, the circular groove is provided with a snap-fit ​​component, and the end of the silicone watch strap is integrally formed with a circular protrusion.

[0008] Preferably, a rectangular notch is provided on the circular protrusion at the position corresponding to the snap-fit ​​component, and the snap-fit ​​component snaps into the rectangular notch.

[0009] Preferably, the locking assembly includes a locking block, and the watch body has an inclined groove that is in communication with a circular groove. The locking block is inserted into the interior of the inclined groove, and one end of the locking block extending into the circular groove engages with a rectangular notch.

[0010] Preferably, the locking block has an integrally formed outer extension protrusion at one end extending to the outside of the watch body.

[0011] Preferably, an inner rectangular groove is formed on the inner wall of the inclined groove, and a slider is integrally formed on the locking block at the position corresponding to the inner rectangular groove. The slider is slidably engaged with the inner rectangular groove, and a spring is fixedly installed inside the inner rectangular groove. The end of the spring is fixedly connected to the slider.

[0012] Preferably, when the spring rebounds normally, it will compress the slider, and one end of the locking block will be inserted into the circular groove.

[0013] Compared with the prior art, the present invention provides a detachable silicone watch strap, which has the following advantages:

[0014] I. Convenient and efficient assembly / disassembly experience

[0015] Tool-free quick installation and removal: The lock can be released by pulling the outer extended protrusion to release the locking block. With the horizontal snap-fit ​​design of the round protrusion and the round groove, users can complete the installation and removal of the watch strap with just one hand, avoiding the cumbersome operation of the traditional spring bar structure that requires tools, and lowering the threshold for use.

[0016] Automated locking mechanism: The elastic driving force of the spring causes the locking block to automatically engage with the rectangular notch after being released, eliminating the need for manual alignment or pressing. This ensures that the watch strap is locked immediately after installation, significantly improving operational efficiency.

[0017] II. Excellent connection stability and reliability

[0018] Double locking structure: The cooperation between the circular protrusion and the circular groove achieves initial positioning, and the locking block and the rectangular notch form a secondary lock. When subjected to lateral force, the locking block is embedded in the notch, effectively preventing the watch strap from falling off. Compared with the traditional single-point buckle structure, the pull-out resistance is increased by more than 30%.

[0019] Dynamic stress buffering: The tilt angle design of the inclined groove, combined with the elasticity of the spring, can absorb the lateral impact force on the strap during wear, preventing the connection from loosening due to vigorous exercise, making it especially suitable for sports scenarios.

[0020] III. Flexible and precise length adjustment

[0021] Multi-position adaptive adjustment: The fixing holes on the silicone strap are evenly distributed, and with the insertion of locking pins, millimeter-level length adjustment can be achieved to adapt to wrist circumferences ranging from 5-20cm, meeting the wearing needs of different users.

[0022] Anti-accidental touch locking design: The chamfered tip of the locking pin fits the arc of the inner wall of the fixing hole, forming an interference fit after insertion. Combined with the elastic deformation of the silicone of the watch strap body, the locking pin is not easy to slip out even after long-term use.

[0023] IV. Human-centered structural design and cost advantages

[0024] Improved operational comfort: The ergonomic design with an extended outer protrusion makes the force application point of the pull-out locking block more in line with the finger's force application habits, reducing the operating force from 8N ​​in the traditional structure to 3N, making it easy for the elderly and children to operate.

[0025] Modular production adaptation: The circular and rectangular grooves of the watch body and the circular protrusions of the watch strap adopt a standardized size design, which supports quick interchange of watch straps of different colors and materials, reducing the replacement cost for end users; at the same time, the springs, sliders and other components of the snap-fit ​​assembly can be injection molded as one piece, which reduces the manufacturing cost by 40% compared with the traditional metal spring bar structure.

[0040] Furthermore, when the spring 14 rebounds normally, it will press the slider 13, and one end of the locking block 10 will be inserted into the circular groove 5. When installation is required, the outer extension protrusion 11 is pulled outward, and then the spring 14 is compressed. One end of the locking block 10 retracts into the inclined groove 9. Then, the circular protrusion 7 is aligned with the circular groove 5 and inserted laterally into the circular groove 5. Then, the silicone strap 2 is located inside the rectangular groove 6. The outer extension protrusion 11 is released, and the spring 14 rebounds, pressing the slider 13. One end of the locking block 10 is inserted into the circular groove 5, and the locking block 10 engages with the rectangular notch 8.
