Analog-type quartz clock with automatic alarming time at selected time

The utility model relates to a kind of to selected automatically alarming quartz analog clock constantly, and it has the structure that is similar to common quartz analog clock, is made of quartz (controlled) oscillator, pointer kinematic train and clamping plate, face, pointer, shell.The automatically alarming that can be used for multiple occasions such as family, institutional settings, instrument, equipment.

At present, commercially available quartz analog clock does not have the selected structure of automatically alarming constantly, therefore, and can not be to selected moment automatically alarming.

The purpose of this utility model just is: common quartz analog clock is improved, design a kind of simple in structure to selected automatically alarming quartz analog clock constantly.

The utility model is to reach its purpose like this: it has the structure that is similar to common quartz analog clock, is made of quartz (controlled) oscillator, pointer kinematic train and clamping plate, face, pointer, shell.Its improvements are: design has music circuit, hilted broadsword 12 to throw step switch in clock, hilted broadsword 24 is thrown step switch, crystal diode coding switch circuit.The two ends of the trigger switch circuit of music circuit throws the moving contact of step switch with hilted broadsword 12 respectively and moving contact that hilted broadsword 24 is thrown step switch is connected in series mutually, hilted broadsword 12 is thrown the static contact of step switch as giving the correct time a minute selection joint, the static contact that hilted broadsword 24 is thrown step switch is connected in series mutually with the crystal diode coding switch circuit, the positive terminal of its crystal diode is as giving the correct time a hour selection joint, hilted broadsword 12 is thrown step switch and is thrown step switch all by synchronous device and the load mutually of quartzy hand of a clock kinematic train with hilted broadsword 24, keep synchronous, the light emitting diode that also is connected to sounder and is in parallel on the music circuit with it with the face timestamp.

The utility model can also be realized its purpose like this: 24 static contacts, crystal diode coding switch circuit that 12 static contacts, the hilted broadsword 24 that hilted broadsword 12 is thrown step switch thrown step switch all design on a face of the option board that gives the correct time, minute selection joint and hour select joint design on another face of the option board that gives the correct time.

Synchronous device of the present utility model is that an end is contained on the minute hand shaft of pointer kinematic train, the other end be contained in hilted broadsword 24 and throw time the synchronous driving lever of 24 tooth hour wheels engagement on the wheel shaft of step switch.

The moving contact that hilted broadsword 12 of the present utility model is thrown step switch is the metallic elastic contact that is contained on the synchronous driving lever, and corresponding static contact keeps in touch on its free end and the option board that gives the correct time.

The moving contact that hilted broadsword 24 of the present utility model is thrown step switch is the metallic elastic contact that is fixed on the 24 tooth hour wheels, its free end with give the correct time that corresponding static contact keeps in touch on the option board, its other end conducting sheet on the wheel shaft when being contained in is connected in series mutually with a termination of the trigger switch circuit of music circuit.

The minute hand shaft of wheel shaft two ends and pointer kinematic train all is bearing in the clamping plate of crystal clock and gives the correct time on the option board when of the present utility model, between clamping plate and 24 tooth hour wheels the time wheel shaft on and on the minute hand shaft between clamping plate and the synchronous driving lever soft stage clip is housed respectively.

Principle of work of the present utility model is as follows: during use, according to user-selected give the correct time hour and minute, be communicated with will give the correct time on the option board corresponding hour selection joint and minute selection joint of lead, because hilted broadsword 12 is thrown step switch and hilted broadsword 24 and is thrown step switch and all keep synchronous by synchronous device and quartzy hand of a clock kinematic train, thereby keep synchronously with the face timestamp, be that the minute hand rotation is during one week, driving lever rotates a week synchronously, drive dress hilted broadsword 12 thereon and throw the moving contact of step switch---the slip of metallic elastic contact, touch 12 static contacts successively, rotate in the process in a week at synchronous driving lever, stir 24 tooth hour wheels, one tooth, hilted broadsword 24 then fixed thereon is thrown the moving contact of step switch---and the metallic elastic contact will slide further, be one hour, touch 24 static contacts so successively.When the face timestamp reach selected give the correct time hour and minute the time, then music circuit, hilted broadsword 12 are thrown step switch, crystal diode coding switch circuit, hilted broadsword 24 and are thrown the series loop that step switch forms a conducting, music circuit work, make its sounder and light emitting diode of being connected on this music circuit send sound, light, carry out automatically alarming.

Because utility model has adopted above-mentioned structure, have additional in common quartz analog clock that music circuit, hilted broadsword 12 are thrown step switch, hilted broadsword 24 is thrown step switch and crystal diode coding switch circuit, sounder and light emitting diode, and make hilted broadsword 12 throw step switch and hilted broadsword 24 is thrown step switch and the face timestamp is synchronous by synchronous device, simple in structure, suitable, can carry out automatically alarming by the selected moment, the precision of giving the correct time is the same with common crystal clock, can be used for the automatically alarming selectively of multiple occasions such as family, institutional settings, instrument, equipment.
