Document Type and Number:
WIPO Patent Application WO/2019/052517
Kind Code:
A1
Abstract:
Provided is a length adjuster on a wearable device, comprising an arc-shaped shell and a length fine-adjustment mechanism, wherein a first connection rack (21), a second connection rack (22), a gear (3), and a button (4) and a return spring (40) of a gear shaft (30) are provided in the arc-shaped shell; the first connection rack (21), the second connection rack (22) and the gear (3) are meshed with one another; the gear shaft (30) is connected to a clockwork spring mechanism, the gear shaft (30) and the length fine-adjustment mechanism are in a clutch connection, and the gear shaft (30) and the length fine-adjustment mechanism may be in a clutch connection; and a unidirectional rotation-prevention structure is provided in the length fine-adjustment mechanism, and the unidirectional rotation-prevention structure allows the length fine-adjustment mechanism to drive the gear shaft (30) to rotate in a rotation direction for enabling a clockwork spring (6) to be stretched, and prevents the gear shaft (30) from rotating in the direction opposite to the rotation direction. The length adjuster is provided with a release mechanism for releasing a rotation-prevention effect of the unidirectional transmission structure in the opposite direction, thereby enabling the length fine-adjustment mechanism to drive the gear (3) to rotate in the opposite direction. The length adjuster is capable of arbitrarily adjusting the length and fine-adjustment length, is simple in structure, is applicable to a wearable device, and facilitates the thin design thereof; in addition, the fine-adjustment operation is convenient, and the handfeel is good.
