[0023] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0024] like Figures 1-5 As shown, this embodiment provides a wear-resistant connector for a smartwatch button, including a crown body 1, a connecting rod 2, and a wear-resistant ring 3.

[0025] The connecting rod 2 is located in the middle of the lower surface of the crown body 1. A sealing groove is formed on the circumference of the connecting rod 2. A downwardly extending annular boss 11 is formed on the lower surface of the crown body 1. A first annular groove 111 is formed on the outer circumference of the annular boss 11. An annular notch 112 is formed at the outer edge of the annular boss located below the first annular groove 111. The diameter of the outer circumference of the annular notch 112 is smaller than the diameter of the bottom circumference of the first annular groove 111.

[0026] The wear-resistant ring 3 includes a locking part 31 and an extension part 32. The locking part 31 is located in the first annular groove 111, and the extension part 32 is located at the annular notch 112. In this embodiment, the wear-resistant ring 3 is made of PEEK or POM.

[0027] The wear-resistant connector provided in this solution has a wear-resistant ring 3 set at the first annular groove 111 and the annular notch 112. After installation, the rotation is smoother, quieter and more wear-resistant. Compared with the button (crown) without the wear-resistant ring 3, which will produce metal powder after rotating for a long time, affecting the button feel, waterproofing and button jamming problems, the wear-resistant connector used in this solution is cheaper than the existing crown with wear-resistant connector.

[0028] This embodiment also provides a combination fixture for a wear-resistant connector for a smartwatch button, used to assemble and produce a wear-resistant connector for a smartwatch button, including a support tube 4, an elastic sleeve 5, a support nozzle 6, a limiting block 7, and a base 8.

[0029] The base 8 has an annular support platform 81, and a through hole 82 is formed in the middle of the annular support platform 81. The lower surface of the support 6 is in contact with the upper surface of the annular support platform 81. Specifically, an insertion ring 64 is formed on the lower surface of the support 6, and the insertion ring 64 extends into the through hole 82.

[0030] The support nozzle 6 has a through hole 61 extending vertically, and a mounting groove 62 with a diameter larger than that of the through hole 61. An annular retaining groove 63 with a diameter larger than that of the mounting groove 62 is formed at the opening of the mounting groove 62. A retaining ring 41 is formed on the outer circumference of the support tube 4. The retaining ring 41 has a diameter larger than that of the through hole 61 but smaller than that of the mounting groove 62. Specifically, an annular retaining groove is provided at the upper outer edge of the retaining ring 41 to hold the wear-resistant ring 3. An elastic sleeve 5 is fitted inside the mounting groove 62. The elastic sleeve 5 is a spring. A retaining block 7 is connected to the lower surface of the support tube 4, and the diameter of the retaining block 7 is larger than that of the through hole 61. Specifically, a boss is formed on the upper surface of the retaining block 7, which is adapted to the through hole 61. The boss is connected below the through hole 61 by an interference fit.

[0031] Preferably, the limiting block 7 and the support tube 4 can be integrally formed.

[0032] Assembly principle: Place the wear-resistant ring 3 on the upper outer edge of the limiting ring 41 of the support tube 4. The locking part 31 of the wear-resistant ring 3 abuts against the upper surface of the limiting ring 41. The extension plate fits against the outer circumferential surface of the limiting ring 41 (that is, it is set at the annular locking slot). This design has a foolproof function. Then, insert the connecting rod 2 into the support tube 4 and press the crown body 1. The annular boss 11 of the crown body 1 and the support tube 4 continue to move downward until the wear-resistant ring 3 is limited in the ring body limiting groove 63. The annular boss 11 continues to move upward, and the wear-resistant ring 3 is locked into the first annular groove 111 of the annular boss 11. Then, under the action of the reset sleeve, the crown body 1 and the connecting rod 2 reset with the assembled wear-resistant ring 3. At this time, the assembly of the wear-resistant ring 3 is completed.
