Abstract
Description
Technical Field
[0001] This utility model relates to the field of watch structure technology, and in particular to an anti-rotation watch structure suitable for users with small wrist diameters. Background Technology
[0002] Currently, whether it's a smartwatch or a mechanical watch, the strap length usually has multiple adjustment holes or buckle structures to fit different users' wrist sizes. However, even when the strap is adjusted to the shortest usable length, i.e., the smallest hole, for users with thinner wrists, such as some women, teenagers, or children, the watch face is still difficult to fit snugly against the bony prominence of the wrist. More importantly, actual wearing habits show that most users, for comfort reasons, do not fasten the watch too tightly, but tend to leave a certain amount of space between the strap and the wrist. While this comfort provision improves the daily wearing experience, it also causes the watch face to easily rotate around the wrist axis and float and wobble in the vertical direction.
[0003] Such shaking can also cause discomfort due to repeated impacts of the watch case against the bony prominence of the wrist. For smartwatches equipped with physiological sensors, shaking can significantly reduce the accuracy of data collection such as heart rate and blood oxygen. For mechanical watches, long-term shaking may also exacerbate abnormal wear and tear on the internal parts of the movement. While existing technologies attempt to improve the fit by adding extra strap holes, using shortening loops, or inner padding, these methods only reduce the strap circumference to a limited extent and cannot fundamentally restrict the dial's rotational freedom and vertical displacement relative to the wrist. Therefore, there is an urgent need for a structural design that does not rely on excessively tightening the strap to effectively suppress dial rotation and wobble while ensuring wearing comfort. Utility Model Content
[0004] The purpose of this invention is to provide an anti-rotation watch structure suitable for users with small wrist diameters. Its core lies in solving the technical problem of not relying excessively on overtightening the watch strap, but generating resistance during each shaking or rotation to prevent excessive deflection.
[0005] According to one aspect of this utility model, an anti-rotation watch structure suitable for users with small wrist diameters is provided, including a dial, a watch strap, and a pair of strap connectors. The pair of strap connectors are respectively disposed on the outer surfaces of both sides of the dial and detachably connected to the watch strap. The characteristic of this invention is that... The watch face has an inner surface facing the wearer's skin and an outer surface facing away from the skin. Each of the watch strap connectors is movably connected to the watch face via a pivot. The pivot is provided with a flexible adaptive connector on the side near the inner surface. The flexible adaptive connector is configured to conform to the curvature of the wrist when worn and increase the frictional resistance between the watch face and the skin, thereby suppressing the rotation of the watch face relative to the wrist.
[0006] Preferably, the inner surface of the dial is provided with an anti-slip layer, which is made of silicone or rubber material.
[0007] Preferably, it also includes a tape winding assembly and a card slot disposed on the inner surface of the dial, wherein the tape winding assembly and the card slot are respectively located on opposite sides of the inner surface of the dial; The tape assembly includes an anti-slip tape, a winding shaft, and a torsion spring. One end of the anti-slip tape is fixed to the winding shaft and can be rolled up and stored, while the other end is provided with a snap-fit part. The winding shaft is elastically supported in the inner surface of the dial by the torsion spring, so that the anti-slip tape can automatically retract after being pulled out. The slot is configured to detachably engage with the snap-fit portion to place the anti-slip band across the back of the wearer's wrist, forming an auxiliary fixing band.
[0008] Preferably, the outer surface of the anti-slip strip is made of nylon fabric.
[0009] Preferably, the flexible adaptive connector is an arc-shaped silicone pad or a thermoplastic elastomer pad, the radius of curvature of which matches the contour of the back of the wrist. The beneficial effects of this utility model are: This invention features a flexible, self-adaptive connector on the inner side of the pivot between the strap connector and the dial. This connector conforms to the wrist curve of users with small wrists when worn, increasing the local frictional resistance between the dial and the skin. This effectively suppresses the rotation of the dial around the wrist axis, solving the problem that existing watches, even when adjusted to the shortest strap length, still allow for comfort gaps that cause the dial to easily rotate and wobble. This improves wearing stability, avoids discomfort caused by repeated impacts of the watch case against the wrist bony prominence, and eliminates the need for excessively tightening the strap, thus balancing the comfort and reliability of users with small wrists.

[0011] List of reference numerals in the figure Detailed Implementation
[0012] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0013] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0014] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Please see Figure 1-6 As shown, this utility model discloses an anti-rotation watch structure suitable for users with small wrist diameters, including a dial 1, a strap 2, and a pair of strap connectors 3. The pair of strap connectors 3 are respectively disposed on the outer surfaces of both sides of the dial 1 and are detachably connected to the strap 2. The dial 1 has an inner surface 12 facing the wearer's skin and an outer surface 11 facing away from the skin. Each strap connector 3 is movably connected to the dial 1 via a pivot 4. A flexible adaptive connector 5 is provided on the side of the pivot 4 near the inner surface 12. The flexible adaptive connector 5 is configured to conform to the curvature of the wrist in the wearing state and increase the frictional resistance between the dial 1 and the skin, thereby suppressing the rotation of the dial 1 relative to the wrist. The flexible adaptive connector 5 is located on one side of the wearer's skin and in the direction of the inner surface 12. This flexible adaptive connector 5 is made of a highly elastic, low-hardness flexible material. When worn by the user, it deforms under the pressure of the curved surface of the back of the wrist, closely conforming to the contours of the skin. This creates a localized high-friction area between the dial 1 and the skin, effectively resisting the tendency of the dial 1 to rotate around the wrist axis due to arm movement or gravity. This design is particularly suitable for users with smaller wrist circumferences, such as less than 15cm, because their wrist curvature radius is smaller, making traditional rigid watch cases more prone to slippage or flipping.
[0015] The inner surface 12 of the dial 1 is provided with an anti-slip layer 6, which is made of silicone or rubber material. The anti-slip layer 6 is fixed to the outer ring of the bottom shell of the dial 1 by bonding or embedding. Figure 2-3As shown, when a user wears the watch, the anti-slip layer 6 is in direct contact with the skin, providing basic anti-slip protection. It works in conjunction with the flexible adaptive connector 5 to form a dual anti-rotation mechanism that combines points and surfaces, thereby reducing the range of shaking and preventing the watch face 1 from rotating and not being in close contact with the wrist.
[0016] It also includes a tape winding assembly 7 and a card slot 8 disposed on the inner surface 12 of the dial 1, wherein the tape winding assembly 7 and the card slot 8 are respectively located on opposite sides of the inner surface 12 of the dial 1; The tape assembly 7 includes an anti-slip tape 71, a winding shaft 72, and a torsion spring 73. One end of the anti-slip tape 71 is fixed to the winding shaft 72 and can be rolled up and stored. The other end is provided with a snap-fit part 74. The winding shaft 72 is elastically supported in the inner surface 12 of the dial 1 by the torsion spring 73, so that the anti-slip tape 71 can automatically retract after being pulled out. The slot 8 is configured to be detachably engaged with the snap-fit part 74 to place the anti-slip band 71 across the back of the wearer's wrist to form an auxiliary fixing band; The winding assembly 7 is embedded in the cavity on one side of the bottom case of the dial 1. Its core is a rotatable winding shaft 72. The shaft 72 obtains the winding torque through a pre-tightened torsion spring 73. One end of the anti-slip band 71 is anchored to the shaft 72 and is normally wound and stored in the cavity. When in use, the user pulls the anti-slip band 71 out from one side of the dial 1 and inserts it into the slot 8 on the other side of the dial 1 to lock it. At this time, the anti-slip band 71 forms a horizontal restraint band on the back of the wrist, which together with the watch band 2 forms a ring-shaped fixing structure, which significantly improves the torsional resistance of the dial 1. This design is especially suitable for scenarios such as vigorous exercise or when the wrist is too thin to fully tighten the watch band 2. At the same time, the anti-slip band 71 forms an elastic barrier between the wrist and the dial 1, reducing the contact area between the dial 1 and the wrist and improving the heat dissipation of the wrist. The slot 8 can be a U-shaped opening or a press-lock to ensure a secure engagement and easy release.
[0017] The outer surface of the anti-slip strip 71 is made of nylon fabric to enhance its anti-slip performance. The nylon material has both abrasion resistance, flexibility and moderate elasticity, and can maintain good grip even in sweaty or wet environments.
[0018] The flexible adaptive connector 5 is an arc-shaped silicone pad or thermoplastic elastomer pad, whose radius of curvature matches the contour of the back of the wrist; the flexible adaptive connector 5 can also have a built-in microporous structure or honeycomb cavity to further improve compression resilience and breathability, and reduce the stuffiness caused by wearing for a long time.
