Indicating mechanism of watch

Abstract

The invention discloses an indicating mechanism of a watch, which comprises an upper minute wheel, a hour wheel, a rotating and positioning structure, a hour disk wheel, a hour disk, a bottom plate, a large gasket and a positioning pin, wherein the upper minute wheel is meshed with the hour wheel; the hour disk wheel is axially fixed on the hour wheel through the rotating and positioning structure; the hour disk is pivoted on the hour disk wheel and synchronously rotates with the hour disk wheel; the large gasket is fixed on the bottom plate; and the positioning pin is installed on the large gasket. The indicating mechanism disclosed by the invention has the beneficial effects that the structure enables the continuous revolution motion of the hour wheel to be converted into the unidirectional stepping rotation of the hour disk wheel because the large gasket is still maintained to be static and the positioning pin enters or departs from the slot of the hour disk wheel in time; the mechanical efficiency is high; and the print wheel transposition can be stably and intermittently realized, thereby realizing the time indicating function.

Description

technical field [0001] The invention relates to a watch part, in particular to an hour number indicating mechanism of a watch. Background technique [0002] Along with the continuous development of people's pursuit of new and strange psychology, people no longer satisfy the conventional indication mode of wristwatch, promptly comprise the pointer indicating hour, minute on the dial of wristwatch; The style of wristwatch is also more and more novel. For example, European patent EP0425430A1 discloses a dial with an hour plate showing hour numbers and indicating minutes at the same time, which makes the watch look more vivid and novel, and increases the appreciation and artistry of the watch. figure 1 It is a plane schematic diagram of the watch mechanism of European patent EP0425430A1. like figure 1 As shown, the working principle of this structure is that the sub-wheel drives the intermediate wheel part, and the intermediate wheel part is transmitted to the hour wheel.

Problems solved by technology

This structure has the following defects. Due to the positioning of the positioning rod spring, there is an instantaneous large rigid shock and vibration when the hour is switched, which has a great impact on the travel time. Moreover, due to the large distance between the center of the fixed position nail and the large distance between the center of the hour dial The torque required for the rotation of the wheel is large, so the torque loss to the watch is relatively large
