Abstract
The utility model discloses a quartz clock capable of timing and alarm once for every 24 hours. The timing and alarm range is 24 hours. The utility model alarms once every day and night for 15-20 seconds every time, stops automatically, and alarms again automatically in the original fixed time of the next day. The utility model has four switches to control four different alarm sounds, such as the sounds of cock crow, folk music, etc., at the use's choice.
Description
The utility model relates to and improves a kind of quartz alarm clock, makes it locking in 24 hours scopes, whenever makes a noise once round the clock, has 4 grades of sound that make a noise optional, and works the quartz alarm clock that makes a noise and close automatically automatically.
At present, commercially available quartz alarm clock locking scope is all in 12 hours, and surpassing 12 hours continuously can not locking; Again because of with 12 hours be cycle period, so will make a noise twice in one day, make troubles to the user.And existing electricity is very long noisy perdurability, approximately will ring half an hour.In case owner does not exist, unmanned ending makes a noise, and it just rang always and just stop the waste electric energy to about half an hour.
The purpose of this utility model is that will to design a kind of locking scope be 24 hours quartz alarm clock, promptly whenever makes a noise once round the clock, makes a noise between time-delay to be 15 to 20 seconds, to stop automatically at every turn.Automatically repeated to make a noise by former fixing time next day again.The sound sound that makes a noise has fourth gear to select for use arbitrarily.
The utility model is to implement like this: 24 hours locking plates that a sign daytime and night are set in one side of crystal clock letter disk.The diameter of locking plate is identical with the crystal clock letter disk.The locking pin indication locking time is arranged on the locking plate, and locking plate and locking pin elastic-friction rotate synchronously.Its rotary power comes from quartz clock movement.Promptly a gear is installed on the needle shaft and need not be changed cassette mechanism structure like this, just power can be drawn dialling of quartz clock movement.Through gear reduction, drive the rotation of locking plate and locking pin, its rotating speed is that hour hands take two turns, then locking plate and locking pin turn around.Alarming cam together is installed on the locking needle shaft, is stirred bounce-back formula contact reed, the triggering electronic music integrated circuit rises noisy, makes a noise through 15 to 20 seconds and finishes, outage automatically.Repeated to make a noise by former fixing time next day again.Sound equipment divides fourth gear when making a noise, and imitates that cock crows and sound equipment such as folk, selects for use arbitrarily.During locking, turn locking knob points to the locking pin on the needed scale.Locking plate and locking pin are along with the operation of crystal clock pointer is also rotated simultaneously, but the indicated locking time is constant.A this locking and a method of making a noise are far different with general commercially available mechanical alarm clock and electronic alarm clock.Locking plate and locking pin are not static, but ceaselessly rotation, thereby driven alarming cam, stir bounce-back formula contact reed, trigger music circuit and rise noisy.The locking principle is the most advanced and sophisticated whiz bounce-back formula contact reed that plays alarming cam, makes it leading or the angle that lags behind, thereby reaches the purpose of having delayed time and having made a noise.If because of rigging error, make the time of rise making a noise of locking plate and locking pin indication inconsistent with hour hands, then locking plate is screwed into the scale of indicating with the locking pin by force with hand and hour hands are consistent gets final product.Disposable adjustment, the long-term use as ending noisy and closing electricity for a long time and make a noise, then promotes the button at alarm clock top, and electricity is noisy to have a power failure, and this moment, crystal clock was only handled the needle when not making a noise.
Below in conjunction with the accompanying drawing description detailed to the utility model:
Fig. 1 is the utility model front view.
Fig. 2 is the rear view that Fig. 1 throws off bonnet.
Fig. 3 is Fig. 2 A-A cut-open view.
Fig. 4 is the left view of Fig. 1.
Fig. 5 is a circuit diagram.
With reference to Fig. 1, the right side is that the quartz alarm clock letter disk is timely, the minute, second pin.The left side is 24 hours locking plates and locking pin.Locking plate is identical with clock letter disk diameter, arranges side by side, and middle small circle (1) " leads to " red, demonstration place of green mark of " breaking " for the acoustic-electric source of making a noise.Top button (2) is the noisy power switch of electricity.
With reference to Fig. 2 Fig. 3.On the transmission wheel axle (5) of quartz clock movement (3), press-fit gear (4) and other gear (7) (8) (9) (10) engagement that a band is dialled pin knob (6), deceleration rear drive locking plate (11) and locking pin (12) circled in per 24 hours.The flexible groove of tubulated ends (13) of gear (10) and mousing-hook (14) are tightly blocked after press-fiting with locking plate (11), but still can be rotated, and are convenient to adjust.Locking pin (12) is injection-moulded in locking needle shaft (15), they and locking plate gear (10), borrow the pressure of spring (17) and play alarming cam (18), pin (19), elasticity links together and rotates synchronously, make alarming cam (18) stir bounce-back formula contact reed (16), triggered music integrated circuit (20) (see figure 5).Send the sound that makes a noise by loudspeaker (21), the Bi Zidong outage of making a noise.Fourth gear selector switch (22), (see figure 2) is in order to select the noisy melody of electricity.Alarm clock ceiling button (2) is the acoustic-electric source switch that makes a noise.The figure meta is changed to "on" position.Noisy acoustic-electric source and loudspeaker are installed in the base.The power supply 3V power supply 1.5V when walking that makes a noise is powered by two Battery packs.
Claims (5)
