Structural improvement of the digital perpetual calendar clock

This creation is about a digital page turning clock, especially for a page turning clock structure that reduces the number of pages.

Regarding the digital flip display clock (Flip Clock), there are many different designs or structures on the market.

The perpetual calendar clock structure described in the Patent Application No. 186349 and the No. M361651 patent application filed by the present applicant is mainly composed of an outer casing, a rotating roller, a driving device and a battery pack, and the like. The pages of numbers are set on the rotating roller according to the number of numbers to be displayed. However, if you want to display the minutes or seconds of the six-digit system, according to the previous design, the rotating roller must be set with sixty passengers. A wide-format page can present numbers from zero to sixty (for example, minutes or seconds).

In the above, the provision of a large number of sheets on the rotating roller causes an increase in the force required to rotate the rotating roller, which in turn affects the power required to provide a driving device for rotating the rotating force of the rotating roller, and the application of such a structure is required to be displayed. When the time is digital and the perpetual calendar clock that has to be operated for a long time is not interrupted, the disadvantages are quite obvious. Therefore, it is known that the prior art is not perfect and needs to be improved.

The creators of this case have given up the various shortcomings derived from the above-mentioned customary items. Point, Nai Si thought to improve and innovate, and after years of painstaking research, finally successfully developed and completed the structural improvement of this perpetual calendar clock

In response to the above problems, the inventor of this creation has made a long-term study in this field of expertise to conceive the original creation. This creation can deal with various shortcomings derived from the deficiencies of the prior art, and provides a practically industrial application. The novelty of the perpetual calendar clock is new.

This creation is a structural improvement of the digital perpetual calendar clock, which is a page turning clock that mechanically drives the page to flip the page to display the number. Compared with the prior art, the number of pages set is small, supplemented by intermittent driving. The driving of the device can make the clock of the creation step by step, can achieve the effect of consuming very little power, and can also save manufacturing cost.

The digital perpetual calendar clock structure improvement of this creation includes the following components:
