The utility model is characterized in a gear, wherein, one surface of the gear is printed or pasted moon and star patterns. The gear is driven to rotate by a poking tooth or a gear on a needle tubular shaft of a quartz clock movement, or is driven to rotate by a transmission gear train of a DC motor, and the rotation period is fifty nine days corresponding to two months of a lunar calendar. In a small window on a clock panel, a user can see the variation of the moon shape which conforms to the law of the earth and the moon variation. Therefore, lunar calendar or solar calendar dates can be predicted according to the moon shape. The utility model has the advantages of convenience, simple structure and additional decorative effect of the quartz clock.

Description

A kind of crystal clock phases of the moon display device

The utility model relates to crystal clock, particularly relates to the device that shows the phases of the moon in the crystal clock.

It is clocklike that the circle of the moon lack to change the front-month phase change, and the lunar calendar or the lunar calendar are promptly worked out according to this rule, and the date of knowing the lunar calendar or the lunar calendar just can be known the shape of the moon.Otherwise, known that the shape of the phases of the moon just can know the general date of the lunar calendar or the lunar calendar by inference.In addition, the tide bulge and fall and the phases of the moon are closely related and fixing rule is arranged, the junior one, the Fifteenth National Congress tide, the seventh day of lunar month, the eighth day of lunar month, neap on the 22nd, 23, known the date of the lunar calendar or the lunar calendar, arranged fish production and flood control and offshore operation personnel beneficial coastal resident.Therefore, if can in crystal clock that generally uses and quartz alarm clock, add phases of the moon display device, will be a kind of convenient and practical function, yet yet there are no this phases of the moon display device at present popular crystal clock and the quartz alarm clock.

The purpose of this utility model promptly is that a kind of phases of the moon display device that combines with crystal clock will be provided, and this device can show exactly that phases of the moon circle lacks the rule that changes, thereby is convenient to the date that people know the lunar calendar or the lunar calendar by inference.

Technical solution of the present utility model is: is that a scarce period of change of phases of the moon circle is 29.5306 according to the moon around one week of the earth, got its approximate value 29.5, a number of teeth be set be 59 multiple and be the number of teeth and be 59,118,177 or the like gear, have or labeling has the pattern of the moon or also includes the pattern of star at the surface printing of this gear, this gear is by quartz clock movement 12 needle tubing axle or 24 moving tooth or the gear driven rotation of installing on the needle tubing axle constantly constantly, and another kind of scheme is that this gear is by d.c. motor train driven rotary.Corresponding position is provided with one or two special approximate semi-moon shaped wickets of shape on the clock face plate that hides gear, the phases of the moon change of shape of seeing from wicket will be consistent with the phases of the moon Changing Pattern of the moon approx, according to calculating, its error degree 3 is only a difference point more than a day.

From the above, the utility model is simple in structure, the rule that can show moon phase change more accurately, people by day, when can't see the moon in overcast and rainy, have a look at this device and just know what kind of the moon shape on the same day is, and can know by inference in view of the above the date of the lunar calendar or the lunar calendar, this will bring convenience to daily life, after crystal clock is added this device, increase decorative effect for again the outward appearance of product, have certain economic benefits and social benefit.

Embodiment further specifies below in conjunction with accompanying drawing.

Fig. 1 is a kind of synoptic diagram of example structure;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the synoptic diagram of another kind of example structure;

Fig. 4 is the left view of Fig. 3.

See also Fig. 1, Fig. 2, quartz clock movement 1 is installed on the clock shell 2, on 24 o'clock hour hands of movement (or 12 o'clock hour hands) tubular axis a moving tooth 3 is installed, gear 4 is installed on the clock shell 2, axle head is with a knob cap head 6, clock face plate 6 hides gear 4,2 approximate semi-moon shaped wickets are arranged on the clock face plate, see into from window and can see that gear 4 surface prints or " moon " 7 of labeling and the patterns of starry sky, scale on the window circumference divides 59 five equilibriums, 29 days and 30 days of the solar month in corresponding lunar calendar solar month of 30 days of difference, " moon " 7 is with turn around into lunar calendar two months totally 59 days of gear 4, if moving tooth 3 is installed in 24 constantly on the needle tubing axle, then the number of teeth of gear 4 is 59, moving tooth 3 was dialled 4 one teeth of gear every 24 hours, make " moon " turn over one day angle, if moving tooth 3 is installed in 12 constantly on the needle tubing axle, then the number of teeth of gear 4 should be 118, moving tooth 3 was dialled 2 teeth of gear 4 altogether in 24 hours, be 69 days one-periods equally.Be not difficult to find out, it when " moon " 7 is in shown position the full moon shape, the corresponding lunar calendar or the lunar calendar 15 days, when other position, can be covered a part or whole by the circular position on the clock face plate 5, process that its circle lack to change is the change procedure of the corresponding phases of the moon approx just in time, rotary knob cap head 6 can be proofreaded the initial position of " moon " 7.

See also Fig. 3, Fig. 4, when movement has only 12 constantly during the needle tubing axle, can also adopt structure shown in Figure 3, a gear 8 is installed on the hour hands tubular axis, other is provided with a gear 9 and is engaged with, gear ratio is 1: 2, gear 9 is connected as a single entity with moving tooth 3, and by moving tooth 3 handsetting gears 4, at this moment the number of teeth of gear 4 is 59, wicket on the clock face plate can also be made one and a half months shape shown in Figure 4, at this moment " moon " pattern on the gear 4 should have 2, becomes 180 ° of symmetries, when one of them forwards 30 days position to and falls, another then begins to rise from the position of junior one day, and the visual effect of month phase change is similar in appearance to scheme shown in Figure 2.The demonstration of phases of the moon shape can also have other distinct methods, for example the difformity of the moon is printed as a circle by the variation series arrangement of month or two months, a fenestella is opened in the appropriate location on the clock face plate, make in the wicket and every day to occur a moon pattern, its shape is the conversion of phase change rule monthly, needn't describe in detail one by one or draw and so on.

Allow if the clock face size is big, can also make in case of necessity gear 4 directly with 24 meshed transmission gear on the needle tubing axle constantly, ratio of gear is 1: 59, perhaps with 12 gearing mesh on the needle tubing axle constantly, ratio of gear is 1: 118.

In addition, also have a kind of example structure scheme to be, realize substituting the transmission agency of movement 1 with d.c. motor train structure, driven gear 4 or a disk rotation, can draw control signal from clock circuit or in the core device, make motor rotate certain revolution every 24 hours, driven gear 4 or disk turn over 1/59 circle after train is slowed down, and reach the identical purpose effect of aforementioned schemes.Owing to point out those skilled in the art to realize it with different detailed design at an easy rate in view of the above, so needn't describe in detail one by one or draw.Though adopt this scheme structure complicated, when making the platter surface clock, the pattern that the phases of the moon is shown is done arbitrarily greatly and be placed on position away from movement.
