DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1 FIG. 1 is a schematic diagram of the structure of a quick-release watch strap provided by an embodiment of the present invention, and the quick-release watch strap can be applied to the field of watches, especially in watches in which the watch strap is connected as a whole by a plurality of bead assemblies. Specifically, the quick-release watch strap in this embodiment includes a plurality of bead assemblies connected in sequence, and the length of the quick-release watch strap can be adjusted accordingly by disassembling and assembling the bead assemblies.

[0027] Combination Figure 2 As shown, each bead assembly includes a surface bead 1, a bottom bead 2, and two side beads 3 respectively pivotally fixed on both sides of the bottom bead 2, wherein the surface bead 1 is pivotally connected to the bottom bead 2 through a first bolt shaft 4, so that the end of the surface bead 1 away from the first bolt shaft 4 can rotate around the first bolt shaft 4 under driving to fit onto the bottom bead 2 or separate from the bottom bead 2. Preferably, the two side beads 3 are pivotally connected to both sides of the bottom bead 2 by the first bolt shaft 4, which can effectively simplify the overall structural design of the bead assembly to reduce the number of connecting parts, which can not only improve the convenience of assembly operation and production efficiency, but also help reduce manufacturing costs, making the structural design highly practical.

[0028] A second bolt shaft 5 is also connected between the two side beads 3, and a first C-shaped slot 21 matching the second bolt shaft 5 is provided on the surface of the bottom bead 2 facing the surface bead 1, so that the second bolt shaft 5 on the adjacent bead assembly can be reliably matched into the first C-shaped slot 21. Furthermore, the surface bead 1 is equipped with a spring wave nail 11, and the bottom bead 2 is provided with a first slot structure matching the spring head 111 of the spring wave nail 11.

[0029] During the assembly operation of the quick-release watch strap, the second bolt shaft 5 of the adjacent bead assembly can be first assembled in the first C-shaped slot 21, and then the surface bead 1 is driven to rotate around the first bolt shaft 4, while driving the spring wave nail 11 to move toward the bottom bead 2, and the bottom bead 2 squeezes the elastic part of the spring wave nail 11 to elastically deform and shrink and snap into the first slot structure, thereby realizing the snap-fit ​​fixation between the surface bead 1 and the bottom bead 2, so that the end of the surface bead 1 away from the first bolt shaft 4 is continuously pressed onto the bottom bead 2, so that the second bolt shaft 5 is pressed and fixed in the first C-shaped slot 21 of the bottom bead 2, thereby completing the connection between the two adjacent bead assemblies.

[0030] Combination Figure 3 As shown, during the disassembly operation of the quick-release watch strap, first, move one end of the surface bead 1 away from the first bolt shaft 4 in a direction away from the bottom bead 2, so that the elastic part of the spring wave nail 11 on the surface bead 1 undergoes elastic deformation and shrinks, and disengages from the first slot structure, and then drive the surface bead 1 to rotate around the first bolt shaft 4 to separate from the bottom bead 2, and take the second bolt shaft 5 of the adjacent bead assembly out of the first C-shaped slot 21, completing the disassembly operation between the two adjacent bead assemblies.

[0031] The above-mentioned quick-release watch strap is achieved by pivotally connecting the surface bead 1 and the bottom bead 2 together, and pressing the surface bead 1 onto the bottom bead 2 in a snap-fit ​​manner, so as to press the second bolt shaft 5 of the adjacent bead assembly onto the bottom bead 2, thereby realizing the assembly connection between the two adjacent bead assemblies. This not only achieves the quick-release function (i.e., the disassembly and assembly operation can be completed without the aid of tools), but also effectively simplifies the structure of the bead assembly, making disassembly and assembly more convenient and quick, thereby improving operating efficiency.

[0032] In addition, since the surface bead 1 is connected to the bottom bead 2 by means of the spring wave nail 11, the connection between the surface bead 1 and the bottom bead 2 can be smoother and more stable, and the operation is more controllable, thereby effectively preventing the problem of jamming and avoiding violent removal damage or harm to the quick-release watch strap.

[0033] In one embodiment of the present invention, both ends of the first bolt shaft 4 and the second bolt shaft 5 are fixedly connected to the opposite sides of the two side beads 3, and to ensure the structural rationality of the quick-release watch strap, the first bolt shaft 4 and the second bolt shaft 5 are respectively arranged in parallel along the width direction of the bottom bead 2. In practical applications, the distance between the first bolt shaft 4 and the second bolt shaft 5 can be determined according to actual conditions, and the length of the quick-release watch strap can be adjusted by controlling the distance between the first bolt shaft 4 and the second bolt shaft 5 while ensuring the twisting flexibility of the quick-release watch strap.

[0034] Specifically, the tail end of the bottom bead 2 has two convex edges 23 protruding toward the surface bead 1, and the two convex edges 23 are respectively provided with a first through hole arranged coaxially along the length direction perpendicular to the bottom bead 2, so that the bottom bead 2 can be hinged to the first bolt shaft 4 through the first through holes of the two convex edges 23 to achieve pivotal fixation with the two side beads 3.

[0035] The two flanges 23 are respectively arranged along the length direction of the bottom bead 2, and when the bottom bead 2 is hinged and fixed to the first bolt shaft 4, the outer side surfaces of the two flanges 23 are respectively close to the opposite side surfaces of the two side beads 3, avoiding a large gap between the flanges 23 and the side beads 3 to cause the bottom bead 2 to move, thereby effectively improving the connection stability of the bottom bead 2.

[0036] The above-mentioned first C-shaped slot 21 is located at the head end of the bottom bead 2, and the first C-shaped slot 21 is set along the width direction of the bottom bead 2, and at the same time passes through both sides of the width direction of the bottom bead 2 to ensure that the second bolt shaft 5 of the adjacent bead assembly can be smoothly connected to the first C-shaped slot 21.

[0037] Correspondingly, the surface of the belt bead 1 facing the bottom bead 2 is provided with a second C-shaped slot 12 arranged along the width direction of the belt bead 1 and penetrating the two sides of the belt bead 1 in the width direction, and when the belt bead 1 rotates around the first bolt shaft 4 to fit the bottom bead 2, the opening of the first C-shaped slot 21 coincides with the opening of the second C-shaped slot 12, and together encloses to form a strip-shaped limiting cavity that matches the shape and size of the second bolt shaft 5, so that the second bolt shaft 5 of the adjacent bead assembly can be limited and fixed in the above-mentioned strip-shaped limiting cavity to achieve the assembly connection between the two adjacent bead assemblies. In addition, the second bolt shaft 5 is limited by the first C-shaped slot 21 and the second C-shaped slot 12, which can improve the stability of the pivot connection of the second bolt shaft 5, so that the rotation operation of the bead assembly around the second bolt shaft 5 is smoother.

[0038] Of course, in actual applications, the second bolt shaft 5 of the adjacent bead assembly can also be completely embedded in the first C-shaped slot 21, and the opening of the first C-shaped slot 21 can be directly crimped and sealed from the surface of the belt surface bead 1 toward the surface of the belt bottom bead 2 to press the second bolt shaft 5 into the first C-shaped slot 21, thereby eliminating the need to set the second C-shaped slot 12 on the belt surface bead 1, effectively simplifying the structural design of the belt surface bead 1 and facilitating the processing of the belt surface bead 1.

[0039] The two convex edges 23 of the bottom bead 2 are respectively arranged on the two side edges of the width square of the bottom bead 2, that is, the distance between the outer sides of the two convex edges 23 is equal to the width dimension of the bottom bead 2. In addition, since the outer sides of the two convex edges 23 are respectively close to the opposite sides of the two side beads 3 (that is, the width dimension of the bottom bead 2 is smaller than the distance between the two side beads 3), and the first C-shaped slot 21 is arranged along the width direction of the bottom bead 2 and penetrates through it, when the second bolt shaft 5 of the adjacent bead assembly is clamped into the first C-shaped slot 21, the head end of the bottom bead 2 can be embedded between the two side beads 3 of the adjacent bead assembly, and the two side surfaces of the head end of the bottom bead 2 in the width direction can be close to the opposite sides of the two side beads 3 of the adjacent bead assembly, which not only makes the second bolt shaft 5 and the first C-shaped slot 21 have the largest contact surface, ensuring the connection stability between the bottom bead 2 and the second bolt shaft 5 of the adjacent bead assembly, but also effectively prevents the relative movement between the two adjacent bead assemblies.

[0040] The width of the surface bead 1 is the same as that of the bottom bead 2, so that the two ends of the first C-shaped slot 21 in the length direction are respectively flush with the two ends of the second C-shaped slot 12 in the length direction, so as to make the structure more compact and avoid gaps that are easy to accumulate dust.

[0041] In another embodiment of the present invention, the tail end of the belt surface bead 1 has a protruding pivot portion 13, and the pivot portion 13 is provided with a second through hole 131 penetrating along the width direction, and the belt surface bead 1 is hingedly fixed to the first bolt shaft 4 through the second through hole 131 to achieve pivotal fixation with the belt bottom bead 2.

[0042] Furthermore, since the width of the pivotal portion 13 is smaller than the distance between the two convex edges 23 of the bottom bead 2, when the face bead 1 is hingedly fixed to the first bolt shaft 4, the pivotal portion 13 of the face bead 1 can be embedded between the two convex edges 23, making the overall structural design of the quick-release watch strap more reasonable and practical. Of course, it is preferred that the two side surfaces of the pivotal portion 13 in the width direction are respectively close to the opposite side surfaces of the two convex edges 23 to avoid movement affecting the connection stability of the face bead 1.

[0043] The pivoting portion 13 is provided with an assembly hole 132, which passes through both sides of the pivoting portion 13 in the width direction, and the spring wave nail 11 is installed in the assembly hole 132. Specifically, the spring wave nail 11 includes two spring heads 111 provided at both ends, and the two spring heads 111 protrude from two side surfaces in the width direction of the pivoting portion 13 respectively.

[0044] The first clamping groove structure includes grooves 22 respectively arranged on opposite sides of the two convex edges 23, and the grooves 22 of the two convex edges 23 are respectively matched with the two spring heads 111 of the spring wave nail 11. Therefore, the two spring heads 111 can be respectively inserted into the grooves 22 of the two convex edges 23 to clamp and fix the spring wave nail 11 between the two convex edges 23.

[0045] To ensure that the two spring heads 111 of the spring wave nail 11 can be reliably inserted into the grooves 22 of the two convex edges 23 respectively, the distance between the two spring heads 111 of the spring wave nail 11 should be greater than the distance between the opposite sides of the two convex edges 23.

[0046] In practical applications, it is preferred to make the distance between the two grooves 22 greater than the distance between the two spring heads 111 of the spring wave nail 11. In this way, when the two spring heads 111 of the spring wave nail 11 are respectively inserted into the grooves 22 of the two convex edges 23, the two spring heads 111 can be respectively in a squeezed contraction state, which can not only prevent the spring heads 111 from moving in the grooves 22, but also enable the two spring heads 111 to maintain elastic force to continuously push the grooves 22, so that the clamping between the spring wave nail 11 and the two convex edges 23 is more firm and reliable.

[0047] Since the assembly hole 132 of the bead 1 is located between the second through hole 131 and the second C-shaped slot 12, the engaging position (i.e., the assembly hole 132) can be kept at a relatively large distance from the end of the bead 1 away from the first bolt shaft 4, so that the two spring heads 111 of the spring wave nail 11 can be disengaged from the grooves 22 of the two convex edges 23 by the end of the bead 1 away from the first bolt shaft 4. Of course, the arrangement of the assembly hole 132 of the bead 1, the second through hole 131, and the second C-shaped slot 12 can be adjusted accordingly according to actual conditions, for example, the assembly hole 132 is arranged on the side of the second C-shaped slot 12 facing away from the second through hole 131, but this will greatly increase the design difficulty of the overall structure of the bead assembly.

[0048] The above-mentioned bead assembly is provided with two convex edges 23 on the bottom bead 2 and a pivot part 13 on the surface bead 1. Therefore, while ensuring the overall structural strength of the bead assembly, the thickness of the overlapping surface bead 1 and the bottom bead 2 can be reduced. The overlapping thickness of the surface bead 1 and the bottom bead 2 is made to be the same as the thickness of the two side beads 3, which makes it easier to make the outer sides of each part flush with each other, avoids the occurrence of concave and convex structures, and improves the comfort of the wearer.

[0049] The outer edge of the head end of the surface of the bottom bead 2 facing the surface bead 1 is provided with a nail avoidance position 24, and when the surface bead 1 is attached to the bottom bead 2, at least a part of the outer edge of the end of the surface bead 1 facing the bottom bead 2 is exposed from the nail avoidance position 24. Therefore, when the quick-release watch band is disassembled, the outer edge of the end of the surface bead 1 exposed from the nail avoidance position 24 can be buckled by the finger nail, so as to pry the surface bead 1 apart, thereby improving the convenience of the disassembly operation.

[0050] In another embodiment of the present invention, a boss 25 protruding along the opening of the first C-shaped slot 21 is provided between the opening of the bottom bead 2 and the outer edge of the head end of the bottom bead 2, and the boss 25 and the outer edge of the head end of the bottom bead 2 form a first step structure. Correspondingly, a recess 14 embedded in the opposite direction of the opening of the second C-shaped slot 12 is provided between the opening of the second C-shaped slot 12 of the face bead 1 and the outer edge of the end of the face bead 1, and the recess 14 and the outer edge of the end of the face bead 1 form a second step structure.

[0051] Therefore, when the surface bead 1 is fitted to the bottom bead 2, the boss 25 of the bottom bead 2 will be inserted into the recess 14, so that the first step structure and the second step structure are engaged and snap-fitted, so as to cover and close the strip limit cavity in a step structure cooperative manner, thereby increasing the limiting capacity of the strip limit cavity, greatly improving the connection strength between the two adjacent bead assemblies, and avoiding the two adjacent bead assemblies from being subjected to a large pulling force respectively (causing the spring wave nail 11 to be squeezed and contracted to detach from the first slot structure) and causing the second bolt shaft 5 to detach from the strip limit cavity.

[0052] In addition, the quick-release watch strap further comprises a tail bead assembly, which comprises a tail low bead 6 and a belt surface bead 1 pivotally fixed to the tail low bead 6 via a third bolt shaft, and the belt surface bead 1 is attached to or detached from the tail low bead 6 by rotating around the third bolt shaft. A third C-shaped slot 61 is provided on the surface of the tail low bead 6 facing the belt surface bead 1, and the third C-shaped slot 61 is adapted to the second bolt shaft 5 of the belt bead assembly.

[0053] Specifically, the tail low bead 6 is also provided with a second slot structure adapted to the spring wave pin 11 of the belt surface bead 1, and when the second bolt shaft 5 of the belt bead assembly is assembled in the third C-shaped slot 61, the belt surface bead 1 clamps the spring wave pin 11 to the second slot structure of the tail low bead 6, so that the end away from the third bolt shaft presses and fixes the second bolt shaft 5 of the belt bead assembly in the third C-shaped slot 61, thereby realizing the assembly connection between the tail bead assembly and the adjacent belt bead assembly.

[0054] In addition, the end of the tail bead 6 away from the third C-shaped slot 61 is provided with a connection structure 62 for assembling the watch buckle, and the connection structure 62 has a third through hole arranged along the width direction and passing through. The third bolt shaft pivotally fixed to the tail bead 6 and the belt bead 1 is assembled in the third through hole, and the tail bead 6 is assembled and connected to the watch buckle through the third bolt shaft assembled in the third through hole.

[0055] The embodiment of the present invention further provides a watch, which includes a watch strap and a watch clasp, and the watch strap adopts the above-mentioned quick-release watch strap. Specifically, the watch clasp is provided with a fourth through hole adapted to the third bolt shaft, and the fourth through hole is hinged to the third bolt shaft of the tail ball assembly to realize the assembly connection between the watch clasp and the watch strap.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
