With reference to Fig. 1 and 2, Fig. 1 is the sectional drawing of the operating axis of alarm clock of the present utility model in push position, and Fig. 2 is for to draw the sectional drawing of position.

Lower plate 1 of the present utility model shown in Fig. 1, the prominent needle pivot 2 of establishing in its below.Needle pivot 2 is equipped with alarm setting pin, hour hands, minute hand and the second hand of not drawing.This alarm clock is the upper plate 3 of useful resin manufacture also.Upper plate 3 is positioned at the top of lower plate 1, and both are supporting gear group of installations etc. in the lump.Wherein, there are the branch hour hands reduction gearing 4(minute gear and the hour hand gear of needle speed when minute needle speed is kept to all not to draw).Constantly detecting gear 5 interlocks turns round in the hour hand gear of not drawing.The alarm setting gear 6 that is linked to alarm setting pin (not drawing) has the teat 7 of setting, constantly detect gear 5 and have the hole of detecting 8, when detecting hole 8 and return back to and set teat 7 chimerisms, detect gear 5 constantly and fall, thereby make the alarm device action by the elastic force of the spring of not drawing.As shown in Figure 1, set the downside that bar 9 inserts pearl portion 10 usually, drop, also be about to alarm device and be set in OFF (being failure to actuate) state to stop the moment to detect gear 5; But if will set bar 9, allow that then pearl portion 10 falls, also be about to alarm and install action due to ON(toward arrow 11 direction slippages) state.Form teat 13 on the circumference of portion therebetween with the integrally formed alarm setting gear shaft 12 of lower plate 1.The internal diameter 15 of alarm setting gear 6 is slightly smaller than the width of teat 13.When alarm setting gear 6 was assembled toward the below from the top of gear shaft 12, its internal diameter 15 allowed teat 13 pass through in the resilient expansion mode.After teat 13 passed through, these internal diameter 15 buttons terminated in the downside of teat 13, alarm setting gear 6 were positioned to be against by gear shaft 12 supportings whereby the position of lower plate 1.Because it is integrally formed with resin with lower plate 1 to have the alarm setting gear shaft 12 of teat 13, construct very simple.

Fig. 1 demonstrates the feelings portion condition that operating axis 16 is in push position, and Fig. 2 then demonstrates this operating axis 16 and is in the situation of drawing the position.Operating axis 16 is with ester moulding, and its lower end forms pinion wheel 17, and its upper end has handles knob 18.When switching on push position, pinion wheel 17 is engaged in alarm setting gear 6, thus rotation this handle knob and 18 can make alarm setting pin revolution, to set alarm constantly.Switch on when drawing the position, 17 of pinion wheels are engaged in branch hour hands reduction gearing 4, so rotation is handled knob and 18 can be made the revolution of minute hand, hour hands, aim at constantly.The following hole that can insert operating axis 16 with lower plate 1 all-in-one-piece supporting axis 19 is to support the downside of this operating axis 16.The dead eye 20 of upper plate 3 can be for footpath portion 21 in the middle of the chimeric operating axis 16 with the upside of supporting operating axis 16.Being formed on dead eye 20 positions has polygon tube portion 22, skews in order to prevent operating axis 16.If the thickness of the alarm clock of making is big and operating axis 16 when also long, this one 22 effective means of can yet be regarded as.The external diameter of minor diameter part 23 is less than the external diameter of pinion wheel 17, and so just being unlikely when operating axis 16 is in push position conflicts divides hour hands reduction gearing 4.

Operating axis of the present utility model be owing to can be assembled into state as shown in Figure 1 towards arrow 24 directions, and the external diameter of its pinion wheel 17 must be less than dead eye 20, therefore with the external diameter formation of footpath portion 21 in the middle of the operating axis 16 external diameter greater than pinion wheel 17.Owing to can insert towards arrow 24 directions, handling knob 18 just can form any big external diameter, the size of footpath portion 21 external diameters in the middle of not being limited by, and so just might and handle knob operating axis 16 and 18 be configured as one.Therefore, according to operating axis 16 of the present utility model, its formation is: being next to the external diameter of establishing than pinion wheel 17 on the pinion wheel 17 is little minor diameter part 23, establishing above minor diameter part 23 can be chimeric and have than footpath portion 21 in the middle of the pinion wheel 17 big external diameters with dead eye 20, the top forms the large-diameter portion bigger than middle footpath portion 21, promptly handles knob 18.

If operating axis 16 can be inserted toward arrow 24 directions, just then it might be deviate from toward reverse direction.Therefore the utility model also provides and can prevent that not only operating axis 16 from deviating from also can make operating axis 16 to be positioned push position and draw means between the position.For this reason, at the dead eye 20 that is adjacent to upper plate 3 elastic hook 25 that stretches out toward above is set.The number of elastic hook 25 is at least more than two, the mutual subtend in its position.The end of elastic hook 25 has the edge portion 26 of past inside bend.Operating axis 16 is at the flange 27 that forms the abacus pearl above centre footpath portion 21.26 in edge portion is used for suppressing flange 27.When operating axis 16 switched on the push position of Fig. 1, the edge portion 26 of elastic hook 25 fell into the upper valley portion 28 of flange 27.If from then on the position is toward the opposite direction pull operating axis 16 of arrow 24, then elastic hook 25 is pushed open and displacement by flange 27.When move to Fig. 2 draw the position time, 26 in the edge portion of elastic hook 25 falls into the following paddy portion 29 of flange 27 to suppress the mode that buckles into.Can stably operate the aligning of pointer in this position.This moment, the position further also was not easy toward the opposite direction pull of arrow 24 even desire from then on because edge portion 26 embeds paddy portion 29 down.As seen this formation has possessed to deviate to prevent effect and detain the push-and-pull switching effect that ends formula simultaneously.

Fig. 4 is the sectional drawing of another embodiment of the present utility model.In this embodiment, elastic hook 25 is arranged to stretch out toward the below of dead eye 20.Footpath portion 21 belows in the middle of flange 27 is adjacent to.The assembling mode of arrow 24 directions of this embodiment, it is all identical with Fig. 1, embodiment shown in Figure 2 to deviate to prevent to act on and detain to end formula switching effect.

Fig. 5 is the sectional drawing of another embodiment of the present utility model.Have an elastic arm 30 among this embodiment, it stretches out toward the top from lower plate 1 integratedly.This elastic arm 30 is configured in the position that does not hinder timesharing pin reduction gearing 4, alarm setting gear 6.

In above all explanations, so-called alarm setting gear can be to have the setting pin gear of setting pin, and constantly detecting gear can be the hour hand gear with hour hands.

According to the utility model, can make simply constructed alarm clock, because this alarm clock is bigger with the size shape of handling knob for operation, and with operating axis shaping one, not only its operability is more excellent, and manufacturing cost is also lower, also can produce simultaneously to deviate to prevent and detain the effect that only formula push-and-pull is switched.
