Description

Optical mode is intended the pointer electron crystal clock

The utility model belongs to the clock and watch manufacture technology field, is specifically related to a kind of electronic quartz clock that adopts luminous object simulation mechanical indicator.

Since the mankind have invented the mechanical type timing clock, the large tower clock of the fineness with sight of installing on building have left a deep impression to people, the great bell that those are characteristic even become the symbol in certain city, great bell on London for example world-famous turret clock, the Kremlin, the Moscow clock tower or the like.Therefore, the large-scale clock on the buildings high building or in other large-scale environment all great bell with the pointer mode become instruction time people a kind of custom and the preference.After electronic quartz clock comes out, it with punctual timing, simple for structure, cost is low, outstanding advantage such as easily manufactured and progressively replaced the physical construction clock and watch.Electronic quartz clock is except with the digital form demonstration time, to have again with the quartz (controlled) oscillator be movement, with mechanical drive for auxiliary, realized the clock and watch that mechanical indicator rotates, adapted to people's the custom of viewing and admiring.But this mechanical drive mode making is loaded down with trivial details, precision is lower, be easy to wearing and tearing, and its decorative effect will be by means of external light source.

The purpose of this utility model provides a kind ofly both can see pointer, did not need mechanically operated decorative clock that can be luminous again.

The technical solution adopted in the utility model is: optical mode is intended the pointer electron crystal clock and is made of clock dial and control circuit and power supply.Clock dial comprises shell, cover plate, markers, second show luminous point, divide show laser accunputure, the time show parts such as laser accunputure, clock dial film, wherein markers, second show luminous point, divide show laser accunputure, the time show that laser accunputure constitutes by the light-emitting component that is embedded on the clock dial film, the time indicate 12, being evenly distributed in the periphery of clock dial film according to 12 moment of clock and watch, is fixing light-emitting component; Second show luminous point, divide show laser accunputure, the time show that laser accunputure respectively has 60, inside successively by markers, be evenly distributed in week of clock dial film.Control circuit comprises quartz oscillator, frequency dividing circuit, second luminous point matrix driving circuit, beam split pin matrix tube driving circuit, time pin matrix tube driving circuit, control circuit makes the quartz oscillation source transmit control signal to three matrix driving circuit through frequency divider, make clock each instantaneous have one group second luminous point, divide laser accunputure, the time laser accunputure luminous.

Optical mode is intended the pointer electron crystal clock and has been replaced the rotation of mechanical indicator with shiner, and the indoor and outdoors that is mainly used in building needs the place of time indication.Installing of light-pointer clock not only is used for the time indication, and simultaneously also for the brightening environment has increased the sight spot, it and contour of building lamp line enhance each other's beauty, and will make the dim light of night beautiful more grand.Light-pointer clock is fit to be installed in the hall on station, harbour, airport very much, also can be installed on the high building of buildings.With laser accunputure instruction time, more eye-catching than mechanical indicator, particularly night more outstanding, visibility can increase a lot.The contrast prior art the utlity model has following advantage:

1, punctual timing, the brightness height, eye-catching;

2, simple for structure, Installation and Debugging are convenient, and no transmission and rotational parts do not have wearing and tearing, and maintenance capacity is few;

3, power consumption is few, and calibration is convenient;

4, the life-span long, failure rate is low, the reliability height;

5, brightening environment need not floor light night.
