Abstract
Description
Technical Field
[0001] This utility model relates to a smartwatch, specifically a smartwatch with an adjustable strap length. Background Technology
[0002] Traditional smartwatch straps (such as leather or silicone straps) are typically adjusted via a pin buckle through a limited number of holes, or require trimming. This method offers limited adjustment range and cannot provide fine, stepless length adjustments, making it difficult to perfectly accommodate people with different wrist sizes, especially given the significant differences in wrist size between children and adults.
[0003] Traditional watch straps are mostly one-piece or two-piece rigid / semi-rigid structures with a fixed shape, unable to bend flexibly in three dimensions to fit the circular cross-section of the wrist. This can easily lead to wearing them too tightly or too loosely, affecting comfort and potentially impacting the accuracy of readings from components such as heart rate sensors. Utility Model Content

Elastic sheets are provided between the front connecting seat and the front receiving cavity of the middle movable block and between the rear connecting seat and the rear receiving cavity of the middle movable block, so that the front connecting seat and the rear connecting seat can be stretched outward when subjected to force, so as to adapt to different wrist sizes.
[0007] As a preferred technical solution, the rotating fastening structure includes a rotating block disposed on the front connecting seat and a rotating groove on the rear connecting seat; The rotating block is provided with an elastic pin, and the rotating groove is provided with a rotating hole corresponding to the elastic pin. When the watch strap body is connected to the watch strap body, the elastic pin of the rotating block is placed on the rotating hole of the rotating groove, thereby realizing the rotating connection between the watch strap body and the watch strap body.
[0008] As a preferred technical solution, both the front connecting seat and the rear connecting seat are provided with guide blocks. When the front connecting seat and the rear connecting seat are placed on the middle movable block under the action of the elastic sheet, the guide blocks are placed in the receiving cavity.
[0009] As a preferred technical solution, the two ends of the watch strap assembly are respectively provided with a first latching block and a second latching block; The first snap-fit block is provided with a rotating cavity, and the rotating cavity of the first snap-fit block is connected to the rotating block on the front connecting seat; the inner side of the rotating cavity is also provided with a rotating hole, and the elastic pin on the rotating block is placed in the rotating hole; The second snap-fit block is provided with a rotating seat, and the rotating seat is also provided with an elastic pin, which is placed in the rotating hole of the rotating groove.
[0010] The beneficial effects of this utility model are: This utility model watch strap assembly consists of multiple watch strap bodies connected by a rotating buckle structure. Users can easily disassemble or add watch strap bodies according to their wrist size to achieve flexible adjustment of the watch strap length and meet the needs of different people.
[0011] In this invention, the front and rear connecting seats of the watch strap body are connected to the middle movable block through elastic sheets, allowing the watch strap to stretch outward when worn, better conforming to the shape of the wrist and improving comfort and adaptability.
[0012] The rotating fastening structure of this utility model adopts the setting of elastic pin and rotating hole, which enables the main body of the watch strap to be rotatably connected, ensuring that the watch strap can move freely while maintaining a stable connection, and enabling installation and disassembly under the action of elastic pin.
