Abstract
The utility model relates to a day and night display mechanism of an alarm clock, which comprises an hour wheel. The utility model is characterized in that the mechanism also comprises a display wheel, and the gear ratio of an hour wheel and the display wheel in mutual engagement is 1: 12. The utility model has the advantages that the structure is simple and reasonable, the alarm time can be arranged in distinction of day and night, the operation is convenient, and the alarm time setting is more accurate and reliable to users.
Description
The utility model relates to a kind of mechanism, and particularly a kind of alarm clock is indication mechanism round the clock.
Do not divide round the clock on existing alarm clock is set when noisy, use and quite feel inconvenience.
It is a kind of simple and reasonable, easy to use that the purpose of this utility model is to provide, and sets the alarm clock indication mechanism round the clock that can distinguish daytime and night when making a noise.
The purpose of this utility model can reach by following measure: the utility model comprises hour wheel, it is characterized in that: also have the wheel of demonstration, intermeshing hour wheel is 1: 2 with the gear ratio that shows wheel.
The purpose of this utility model can also reach by following measure: hour wheel is a double-layer gear, and gear wheel is 48 teeth, and pinion wheel is 30 teeth, shows that the number of teeth of wheel is 60 teeth, and the pinion wheel in the hour wheel is meshed with showing wheel.Also can be provided with display panel or pointer, and take turns coaxial installation with demonstration.
Fig. 1 is a structure principle chart of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, the utility model comprises hour wheel 1, shows wheel 2, display panel or pointer 3 etc.Hour wheel 1 is a double-layer gear, and gear wheel is 48 teeth, and pinion wheel is 30 teeth; The number of teeth that shows wheel 2 is 60 teeth; Pinion wheel in the hour wheel 1 is meshed with showing wheel 2, and its ratio of gear is 1: 2.That is to say hour wheel 1 rotation two circles, show that wheel 2 just rotates a circle, realize that the noisy snap of twenty four hours shows.Be imprinted on the demonstration wheel 2 indicating (as the sun, the moon or 24 small time takings etc.); Also can indicate display panel or pointer 3 coaxial being contained on the demonstration wheel with being printed on; To distinguish daytime and night.
The utility model has following advantage compared to existing technology: simple and reasonable, and when making a noise Setting can be distinguished daytime and night, and is easy to use, when people being set make a noise more accurately and reliably.
