[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail in combination with the embodiments and drawings. The schematic implementation methods of the embodiments of the present disclosure and their descriptions are only used to explain the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the snap-on bracelet of the present application includes a bracelet body 1, an elastic hinge 2, a snap 3, an elastic locking pin 4, a spring 5 and a locking groove 6.

[0025] The bracelet body 1 constitutes the main structure of the bracelet, and the two ends are connected by an elastic hinge 2, so that the bracelet body 1 can be opened and closed, and the appropriate size can be adjusted according to the size of the wearer's wrist. In order to ensure that the bracelet can be opened and closed smoothly, the material selection of the bracelet body 1 usually adopts a metal material with good strength and toughness. The elastic hinge 2 is designed to ensure that the bracelet can be smoothly opened and closed. In terms of material selection, it is necessary to select materials with strong fatigue resistance, such as spring steel or polymer materials with good elasticity and weather resistance. In addition, in order to improve the reliability of the bracelet in frequent use, a micro shock-absorbing spring or lubricant can be preset inside the elastic hinge 2 to reduce mechanical wear and increase service life.

[0026] The buckle 3 is fixed to one end of the bracelet body 1. When designing, attention should be paid to its surface treatment to prevent scratches. At the same time, it also needs to have good fixing performance to ensure the stability of the bracelet closure. Another key component is the elastic locking pin 4, which is installed at the other end of the bracelet body 1 and matches the buckle 3.

[0027] In addition, the buckle bracelet of the present application is also provided with a spring 5, which is arranged on the inner side of the bracelet, that is, the side close to the wrist, and the spring 5 is connected to the elastic locking pin 4 and force can be applied to the spring 5 through the elastic locking pin 4.

[0028] For example, Figure 3 As shown, the spring 5 can be laterally arranged in the groove on the inner side of the bracelet body 1, and the spring 5 abuts against the elastic locking pin 4, and the spring 5 and the elastic locking pin 4 are located at one end of the bracelet body 1, and a locking groove 6 is provided at the other end. The position of the locking groove 6 matches the position of the elastic locking pin 4, that is, under the action of the elastic force of the spring 5, the elastic locking pin 4 can enter the locking groove 6, thereby realizing the fixation of one end of the bracelet body 1 and the other end.

[0029] During the specific operation process, in the normal state, the spring 5 is compressed to apply pressure to the elastic locking pin 4 so that the elastic locking pin 4 is inserted into the locking groove 6 at the other end, thereby realizing the closing of the bracelet body 1. When it is necessary to unlock the bracelet body 1, only an external force (such as a hand) needs to be applied to the elastic locking pin 4 to apply an outward force, so that the elastic locking pin 4 disengages from the locking groove 6, thereby realizing the unlocking of the bracelet body 1.

[0030] This unique locking device not only increases the convenience and safety during the wearing process of the snap bracelet, but also solves the problem of loosening or even separation of conventional snap jewelry caused by excessive movement.

[0031] Continue to refer to Figure 3 In one embodiment, the bracelet body 1 of the snap bracelet of the present application is composed of two parts, left and right, and corresponding grooves 7 are provided on these two parts. The two opposite grooves 7 on the bracelet body 1 are designed to have a certain depth and a matching shape, so as to ensure that the snap 3 can be firmly embedded and closely combined.

[0032] To further enhance the durability and reliability of the bracelet, an improved design uses an elastic hinge 2 to penetrate the two grooves 7 on the respective components of the bracelet body 1. This connection mechanism allows for a certain degree of play between the parts of the bracelet body 1 and can compensate for the slight displacement or deformation caused by frequent opening and closing. This mechanism largely reduces the loosening problem that is prone to occur in traditional hinges after repeated use. For example, a material with appropriate elasticity can be selected to prepare the elastic hinge 2, and its diameter and hardness can be adjusted to adapt to the characteristics of the bracelet body 1 material and the user's wearing habits. In this case, even after long-term wearing, the bracelet can still maintain a good appearance and connection stability, improving the overall service life and user experience.

[0033] In one embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, the snap 3 structure of the snap bracelet of the present application further includes an outer cover 8 and an inner hook 9. The inner hook 9 is provided on the inner surface of the outer cover 8 and is located at one end of the bracelet body 1. A structure that can match the inner hook 9 is provided at the other end of the bracelet body 1.

[0034] In the present application, the outer surface of the outer cover 8 can be designed to be flat and cover the area where the elastic hinge 2 is located to provide an aesthetic appearance. The inner surface of the outer cover 8 includes the inner hook 9, and a hook that matches the inner hook 9 is provided at the other end of the bracelet body 1. And when the inner hook 9 is in place, there may be a gap between the outer cover 8 and the other end of the bracelet body 1. An anti-disengagement pin 10 can be provided in this gap to prevent disengagement.

[0035] Refer to Figure 4, in one embodiment, the snap bracelet of the present application adopts a unique elastic locking mechanism in its structural design to ensure the stability of the snap 3. Specifically, a positioning block 11 is installed on the inner side of the bracelet body 1 corresponding to the elastic locking pin 4. This design enables the elastic locking pin 4 to effectively displace under external force and be blocked by the positioning block 11 when not under external force, preventing unnecessary movement and deflection of the locking pin, and further ensuring the stability and long-term reliability of the snap 3 during use. When the elastic locking pin 4 moves under inward pressure and contacts the positioning block 11 provided on the inner side of the bracelet body 1, the locking pin is immediately limited. Such a mechanism not only simplifies the locking operation process but also prevents the failure of the bracelet snap 3 due to the stress during wearing and removal.

[0036] For example, the positioning block 11 can be integrated into the locking groove 6, enabling it to withstand normal extrusion stress and avoid positioning failure problems caused by excessive extrusion. This not only meets the convenience of wearing but also takes into account the reliability of the snap bracelet during long-term use.

[0037] Continue to refer to Figure 4 , in one embodiment, for the snap bracelet of the present application, to ensure the elastic recovery performance and long-term reliability of the bracelet, in the bracelet design, the spring 5 is installed in a special sleeve 12, and the special sleeve 12 can provide effective support and protection for the spring 5. The spring 5 is made of high-quality metal material, and its ability to return to its original position after the release of the elastic locking pin 4 is optimized through a specific shape and treatment method to ensure good stability and reliability of the locking mechanism during use. Specifically speaking, this design solves the problem that the effectiveness of the locking device gradually decreases after multiple uses due to wear, enhances the durability of the bracelet under frequent use conditions, and enables consumers to obtain a more lasting satisfactory experience.

[0038] For example, when implementing this function, the metal spring 5 can be installed inside a special sleeve 12 with precisely calculated dimensions to limit the working space of the spring 5, thereby ensuring a more accurate reset movement of the elastic locking pin 4 after each release. At the same time, the elasticity strength and lifespan can be further improved by increasing the hardness of the metal spring 5 wire or adjusting the design parameters of the spring 5. This can not only ensure smooth and reliable locking but also effectively reduce the fatigue failure problems that may be caused by repeated actions.

[0039] In one embodiment, the snap-on bracelet of the present application provides an optimized spring 5 design, which is intended to improve the stability and durability of the bracelet in a closed state. The spring 5 is in the form of a double helical spring 13, replacing the traditional single helical spring 5 structure. This double helical spring 13 design uses two sets of independent and coordinated helical springs 5 to jointly complete the rebound action, effectively ensuring that the elastic locking pin 4 can still achieve a more uniform force distribution after facing various external forces, thereby improving the working efficiency and service life of the locking mechanism. In addition, compared with a single helical spring 5, this innovative design can also significantly reduce the adverse effects of elastic fatigue and physical deformation on the overall function during long-term use, ensuring that the stability of the bracelet locking mechanism is not affected by time and frequency of use.

[0040] For example, one method of technically realizing this feature is to select a suitable material for the spring 5 and finely adjust the fitting clearance between the two spirals. By precisely controlling the length, material and torsion direction of each spring 5 to obtain an ideal double rebound effect, not only the elastic restoring force of the spring 5 itself is enhanced, but also the user-friendly experience and wearing comfort of the bracelet during the opening and closing operation are further improved. Specifically, in order to ensure that this mechanism works effectively and is durable, each part can be precisely manufactured and the positional relationship between the components can be reasonably set so that the double spiral spring 13 can perform at its best. By adopting the above improvements, the present invention can always maintain excellent mechanical performance and aesthetics under a variety of usage conditions.

[0041] In one embodiment, the snap-on bracelet of the present application is provided with a locking groove 6, and the locking groove 6 is provided with a slight tilt angle. This design is intended to ensure that the elastic locking pin 4 can be smoothly inserted when the bracelet is closed. The design of the slight tilt angle can not only compensate for the difficulty of insertion in the case of small angle misalignment, but also make the operation of wearing and removing the bracelet easier and smoother. In order to further improve the stability of the locking groove 6 and the safety of the overall structure, a stop edge 14 is also provided inside. The design purpose of the stop edge 14 is that when withdrawing in the reverse direction, the elastic locking pin 4 will not be easily pulled out, thereby effectively avoiding the phenomenon of the bracelet loosening by itself due to external accidental forces. Such a design not only improves the safety of the wearer, but also brings a more reliable and convenient use experience to the wearer.

[0042] For example, to achieve this design, a precision machining process can be used to apply a certain inclination to the locking groove 6. Usually, this inclination angle can be precisely adjusted according to the elasticity of the specific material used and the expected functional requirements to adapt to different application scenarios. In a specific implementation, the inclination angle of the locking groove 6 is designed to be 1 to 5 degrees, so that when the elastic locking pin 4 enters or exits the locking groove 6, it can move at a relatively gentle angle without resistance. At the same time, the anti-back edge 14 can be arranged on one or both sides of the locking groove 6 by increasing the local thickness to enhance the locking force on the elastic locking pin 4. Through the above measures, this snap bracelet can be locked more firmly, thus providing excellent product performance.

[0043] In one embodiment, for the snap bracelet of the present application, a wear-resistant rubber ring gasket 15 is provided inside the bracelet near the elastic hinge 2. This design increases the friction coefficient between the contact areas of each part of the bracelet. In this way, without interfering with the normal opening of the bracelet, the direct contact between the metal hinge surfaces is reduced, thereby avoiding the wear caused by repeated movement of the opening and closing parts during long-term use and reducing the looseness caused thereby. This innovative structure not only improves the overall service life of the bracelet but also ensures that its appearance beauty is not affected by wear.

[0044] For example, during the actual production process, the wear-resistant rubber material can be precisely molded into a ring gasket of appropriate size to match the inner cavity of the elastic hinge 2. Specifically, the ring gasket can be fixed at the corresponding internal position of the bracelet through a precision injection molding process. In this way, when the bracelet is opened and closed, due to the intervention of the ring gasket, excessive friction between metal parts can be effectively prevented. Such a design demonstrates the precision craftsmanship of the product in details and meets the dual requirements of users for the stability and beauty of the bracelet.

[0045] In one embodiment, the snap bracelet of the present application is designed with a bracelet body 1 having a unique structure. Special structures are provided at both ends of the bracelet body 1 for cooperating with the closing device to achieve a reliable and easily perceivable safe closing. Specifically, the end edge of the bracelet body 1 of the bracelet adopts a stepped design 16. By forming multiple different planes or levels at the edge, when the two ends of the bracelet body 1 are closed, the lock can utilize this special edge structure to give a certain pre-tightening force. This structure provides a clear, physical locking feeling feedback to the user when locking. More importantly, the stepped design 16 ensures that even under long-term frequent use, the closing part of the bracelet can still maintain stability and is not prone to spontaneous unlocking.

[0046] For example, to achieve this feature, during the manufacturing process of the bracelet, a precision mold can be selected to shape the metal or plastic material to ensure that the stepped design 16 has an appropriate thickness and angle, so that it can provide an effective pre-tightening force without hindering the user's wearing and comfort. At the same time, in terms of material selection and surface treatment process, increasing the frictional resistance or setting micro-locking points can also be considered to further improve the safety and reliability of the locking. These measures combined together jointly promote the stability of the bracelet during the opening and closing process and the safe closing effect intuitively felt by the user.

[0047] During the actual operation process, when this device is in use, first, the bracelet body 1 is connected by an elastic hinge 2, so that it can be opened when not worn. When wearing, the user fixes one end of the bracelet on the wrist, and moves the other end closer to the wrist, making the buckle 3 approach the corresponding elastic locking pin 4. As an external force is applied, the elastic locking pin 4 is squeezed and moves inward, and at this time, the spring 5 connected to it is compressed, thus storing a certain amount of elastic potential energy. At the same time, due to the design of the buckle 3, it can be guided to an appropriate position and make the elastic locking pin 4 accurately aligned with the bracelet closing position. When the two parts are adjacent, the user releases the applied pressure. At this time, the compressed spring 5 pushes the elastic locking pin 4 to move outward under the action of its restoring force and engages into the locking groove 6 on the other end of the bracelet, making the whole device firmly closed. In this process, the buckle 3 not only provides an accurate and fast fixing function, but also the elastic locking pin 4 in cooperation with the spring 5 ensures that the bracelet can still maintain a high locking stability and durability even after long-term repeated opening and closing, thus avoiding the phenomenon of loosening and ensuring that the wearer can use the bracelet comfortably and safely for a long time.

[0048] The above is the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
