CN2443403Y - Timing alarm mechanism for quartz clock - Google Patents

Abstract

The utility model relates to a timing alarm mechanism for a quartz clock, which is characterized in that a pair of alarm discs replace a common alarm hand. Time digital scales are marked on the annular surfaces of the discs. The top or the flank of the clock is provided with a small digital display window. The alarm discs can be rotated for aligning a time scale required by alarm to the central point of the window, and thus, the alarm time is arranged well. The operation is convenient and visual. Because the structure can enlarge the scale sizes farthest, the alarm setting error of the alarm clock is reduced and the alarming accuracy is improved. The utility model is especially suitable for new automatic alarm clocks of which the alarm time needs to be arranged according a 24-hour system, so that the superior practicality is obvious.

Description

A kind of crystal clock timing alarm mechanism

The utility model relates to clock, particularly relates to the quartz alarm clock that has locking mechanism.

Existing quartz alarm clock locking is provided with indicating mechanism generally to be had following severally, and a kind of is that an alarm-setting hand is contained on the locking wheel tubular axis, the time indexing then be printed on the clock face; A kind of is that a disk that is printed with the markers digital calibration is contained on the locking wheel tubular axis, and the clock face plate hides it, digital calibration when having a wicket can see setting noisy on clock face; Also having a kind of is that an alarm-presetting disc is installed on the locking wheel tubular axis, the time indexing is printed on clock face parallels anchor ring on; Above-mentioned various scheme respectively has its relative merits, the advantage of first kind of structure is simple, but be used in and by 24 hours systems a new generation of making a noise constantly be set and then manifest shortcoming on the alarm clock automatically, 24 hours scale makings that 12 hours scale makings that timing that Here it is is used and locking are used are printed on the same clock face, make the user produce the mistake of obscuring easily; The shortcoming of second kind of structure is that the diameter of disk must be littler than clock face diameter, thereby the calibration size is little feasible big to the error of making a noise; Indexing was fallen by friction outside being printed on the clock shell easily when the shortcoming of the third structure was.

The purpose of this utility model is that a kind of new timing alarm mechanism scheme that overcomes the various shortcomings of prior art will be provided, and is used for then more apparent its superiority on the quartzy alarm clock automatically of new generation.

The technical essential of the utility model scheme is: sign had 24 hours or 12 hours markers digital calibrations the disk that makes a noise is installed on the locking wheel tubular axis or is installed on the alarm-setting axis bar that stretches out from the movement bonnet on cylindrical anchor ring or on the interior anchor ring, digital display window is arranged on last plane vertical with clock face or side plane position accordingly, look down from the top of clock or see from the side and can see the fixed alarming time that demonstrates the window, according to this technical essential again in conjunction with the prior art measure, can produce diversified specific embodiments, in the embodiment of back explanation, will in detail it be described in detail for example.

Be not difficult to find out according to technique scheme, because making a noise constantly, number separates setting with the timing number of clock face, the visual angle is different again, the user can not produce and obscure mistake, markers digital calibration sign is on the annulus of disk, and the diameter of disk can be done equally greatly even bigger than clock face diameter with the clock face diameter, this just can add the calibration size of high range to greatest extent, make the error of making a noise is dwindled, improved the noisy precision of newspaper of alarm clock, the time indexing be enclosed in the clock shell and can be damaged by friction, and only demonstrating newspaper in window makes a noise constantly, other incoherent number is covered, and it is more terse directly perceived to make that clock face number mark shows, so this New Scheme and existing scheme relatively have its unique practical part.

Describe several embodiment schemes in detail below in conjunction with accompanying drawing.

Fig. 1, Fig. 2, Fig. 3 disclose an embodiment scheme, and Fig. 1 is the front schematic view of alarm clock, and Fig. 2 is the sectional view of Fig. 1, and Fig. 3 is the vertical view of Fig. 1;

Fig. 4,5, the 6th, three different structure synoptic diagram in addition.

See also Fig. 1,2,3, movement 1 is fixed in the clock shell 2, the timing number of 12 hours systems of 3 printings of clock face plate, on the locking wheel tubular axis alarm-presetting disc 4 is installed, it is made by transparent plastic, so that can see the character on the clock face clearly, sign has the markers digital calibration of 24 hours systems or 12 hours systems on the ring surface of alarm-presetting disc 4, simple way is that an adhesive sticker paper tape that has printed digital calibration is pasted up, perhaps directly on the ring surface of dish, print, when clock is loaded onto, divide, load onto transparent front 5 behind the second hand, a breach is arranged at the top of clock shell, sees from top to bottom, can be the digital calibration of seeing the digital display window on alarm-presetting disc 4 ring surfaces from breach, group noisy knob (not shown) at rotation movement 1 rear portion, the central point of the alignment windows that graduates when the newspaper that needs is made a noise, the noisy moment has just set.

Fig. 4, scheme shown in Figure 5 are the distortion of Fig. 2 scheme, transparent front 5 and alarm-presetting disc 4 buckles are installed together, needn't rotate the noisy knob of dialling at movement rear portion when making a noise, as long as directly rotate protecgulum 5 or alarm-presetting disc 4, Fig. 4, Fig. 5 are two kinds of different buckle mounting meanss, and result of use is identical.

Fig. 6 is another kind of frame mode, the inner structure of movement 1 is slightly different with the movement of aforementioned schemes, it stretches out an alarm-setting axis bar from the movement bonnet, and locking wheel tubular axis saves, at this moment as long as alarm-presetting disc 4 is installed on this axostylus axostyle the corresponding rear portion that moves on to clock shell top of display window, as long as directly rotate alarm-presetting disc 4 can be set the moment of making a noise, result of use is easy equally, is subjected to structural restriction but defective is the diameter dimension of alarm-presetting disc 4, is difficult to make equally size of clock face.

Comprehensive above-mentioned each scheme, no matter how structure changes, its basic same characteristic features is that the markers graduated scale aims on the ring surface of alarm-presetting disc, the visual angle of digital display window is to see into from top to bottom or from the side of clock.

Claims (1)

1, a kind of crystal clock timing alarm mechanism, comprise alarm-presetting disc and digital display window, it is characterized in that alarm-presetting disc is installed on the locking wheel tubular axis or is installed on the alarm-setting axis bar that stretches out from the movement bonnet, the markers digital calibration sign of 24 hours or 12 hours is on the cylindrical anchor ring or interior anchor ring of alarm-presetting disc, and digital display window is arranged on last plane vertical with clock face or side plane position.
