Watch crown and wrist-wearing equipment with watch crown

Abstract

The invention discloses a watch crown and wrist-wearing equipment with the watch crown. The watch crown comprises a key rod provided with an external thread, a body, a non-loosening nut and a second non-loosening nut, wherein the body is used for being fixedly connected with the inner side of the watchcase, and the body is provided with a first insertion hole for allowing the key rod to be inserted; the first non-loosening nut is fixedly arranged on the body; the second non-loosening nut and the first non-loosening nut are locked in a one-way mode, the second non-loosening nut is provided withan internal thread used for being connected with the external thread in a matched mode, and the screwing direction of the external thread and the internal thread is the same as the locking directionof the first non-loosening nut and the second non-loosening nut; and the second non-loosening nut can be assembled on the body in advance through the first non-loosening nut, then the key rod is installed, the second non-loosening nut does not affect assembly of the key rod, axial limiting of the key rod can be achieved, and the effect of blind installation of the key rod is achieved. And comparedwith the prior art, by using the watch crown and the wrist-wearing equipment of the invention, assembling is convenient, and the assembling complexity is reduced. The wrist-wearing equipment comprises the watch crown and has the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of wearable devices, and more specifically, relates to a watch crown. In addition, the present invention also relates to a wrist-worn device comprising the above crown. Background technique [0002] The crown is a common component of wristband wearable devices. For example, with the continuous improvement of smart watch functions, the crown has been widely used and has become the mainstream configuration of smart watches, so that the rotation and / or pressing of the crown can be used to achieve alignment. Smart watch control. [0003] In the crown in the prior art, the key rod is fixed by a special circlip structure, so as to limit the axial position of the key rod. [0004] When assembling, it is necessary to insert the key rod into the case from the outside first, and then insert a spring structure specially used for axially limiting the key rod from the inside of the case to realize the fixing of...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from this that it is inconvenient to assemble the button rod with a spring-like structure, so that functional accessories such as sensors and key switches can only be stacked and installed in the case after the button rod is fixed by the ring-type structure, resulting in The overall structure of the crown is loose and cumbersome to assemble
