Description

Technical Field

[0001] The utility model relates to the technical field of metal watchbands, and particularly to a buckle structure for easily adjusting the length of a metal watchband. Background Art

[0002] A watchband is usually formed by connecting multiple watchband blocks. According to needs, the watchband blocks can be spliced or disassembled so that the length of the watchband can adapt to the needs of different users' wrist sizes.

[0003] However, after the installation of multiple watchband blocks of the existing metal watchband, the body beads are located on the outside, which is not beautiful in appearance. Moreover, it is more troublesome to disassemble and replace, and a special tool is needed, which is not convenient for users to replace by themselves. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a buckle structure for easily adjusting the length of a metal watchband to solve the problems put forward in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A buckle structure for easily adjusting the length of a metal watchband, including an inner core pellet. A buckle cover is rotatably arranged on the inner core pellet through a male-female connection. At both ends on one side of the inner core pellet, single-bud pins are arranged. On the inner side wall of the buckle cover, convex grains are arranged. On the inner core pellet, shallow holes matching the convex grains are arranged. On the inner core pellet, a limiting groove is arranged.

[0006] In a preferred embodiment, a perforation is arranged on the inner core pellet. The male-female connection passes through the perforation. And a clamping protrusion is arranged at the middle position of the perforation. A circular clamping groove is arranged at the middle position of the male-female connection. The arrangement of the clamping protrusion and the circular clamping groove can prevent the male-female connection from sliding out of the perforation.

[0007] In a preferred embodiment, on the side of the single-bud pin located inside the inner core pellet, bud teeth are arranged. On the outside of the single-bud pin, circular small bud teeth are arranged to make the connection effect between the single-bud pin and the inner core pellet better.

[0008] In a preferred embodiment, the limiting groove is inclined and matches the single-bud pin. The single-bud pin is not easily pulled out accidentally when placed in the inclined limiting groove.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0010] The utility model utilizes the buckle principle to remove the beads of the watch band body by prying open the buckle cover, thereby changing the total length of the watch band, and then adjusting it to a suitable length to fit the wrist circumference of the consumer. The disassembly and assembly speed is fast, which does not affect the delicate appearance, and fundamentally breaks and replaces the shortcomings that the holes on the side of the traditional watch appearance affect the aesthetic feeling, and the disassembly and replacement are troublesome and difficult. It has the advantages that its structure is easy to disassemble, replace and adjust the length, and when worn on the wrist, the structure is invisible and will not expose the structure to affect the delicate appearance.

[0017] Please refer to Figures 1 - 4 , the utility model provides a buckle structure for easily adjusting the length of a metal watch band, including an inner core granule 2, a buckle cover 1 is rotatably arranged on the inner core granule 2 through a male-female connection 4, both ends of one side of the inner core granule 2 are provided with single bud needles 3, a convex granule 5 is arranged on the inner side wall of the buckle cover 1, a shallow hole 6 matching with the convex granule 5 is arranged on the inner core granule 2, and a limit groove 7 is arranged on the inner core granule 2.

[0018] In a preferred embodiment, a perforation 8 is formed on the inner core granule 2, the male-female connection 4 passes through the perforation 8, and a clamping protrusion is arranged at the middle position of the perforation 8, an annular clamping groove 9 is arranged at the middle position of the male-female connection 4. When the male-female connection 4 passes through the perforation 8, the clamping protrusion can be clamped in the annular clamping groove 9, which can prevent the male-female connection 4 from sliding out of the perforation 8.

[0019] In a preferred embodiment, a bud tooth 10 is provided on one side of the single-bud needle 3 inside the inner core pellet 2. The provision of the bud tooth 10 makes the connection effect between the single-bud needle 3 and the inner core pellet 2 better.

[0020] In a preferred embodiment, the limiting groove 7 is inclined, and the limiting groove 7 is matched with the single-bud needle 3. When the single-bud needle 3 is placed in the limiting groove, due to the inclined setting of the limiting groove 7, the single-bud needle 3 is not easily slipped out of the limiting groove 7.

[0021] The working principle of the present utility model:

[0022] When the length of the watch band needs to be adjusted, first assemble a single watch band. During assembly, insert the single-bud needle 3 into both sides of the inner core pellet 2, insert the male-female connector 4 into the through hole 8, so that the clamping protrusion inside the through hole 8 is snapped into the annular clamping groove 9, and then buckle the buckle cover 1 on the inner core pellet 2. The jack inside the buckle cover 2 is docked with the male-female connector 4 to complete the assembly of a single watch band. After the assembly is completed, open the buckle cover 1 at the end of the watch band, place the single-bud needle 3 on the assembled watch band into the limiting groove 7 of another watch band, and then buckle the buckle cover 1. After the buckle cover 1 is buckled, the convex particle 5 is snapped into the shallow hole 6 to realize the limit fixation of the buckle cover 1, thereby realizing the adjustment of the length of the metal watch band, having the advantages of fast disassembly and assembly speed and not affecting the delicate appearance.
