Embodiment

The embodiment that provides below by accompanying drawing is further described in detail the utility model.

See also Fig. 1, Fig. 2, hour wheel tubular axis 1 is the part of hour wheel tubular axis in the watch and clock movement among the figure, 12 hour wheels 2 are installed on it, 24 hour wheels 6 are engaged with, the number of teeth of 24 hour wheels 6 is two times of 12 hour wheels 2, therefore when 12 hour wheels circled in per 12 hours, 6 of 24 hour wheels circled in per 24 hours, and protruding shifting block 7, shifting block 8, shifting block 9 are arranged on 24 hour wheels 6; Be coaxially installed with calendar gear 3 with machine mandrel, it has 31 teeth, and there is an independently double wedge 4 31 days of corresponding big month on the calendar gear 3, also have a moving tooth 5; Go through in week to have on the gear 10 and count code-disc 15 week one by one; Lever 12 can rotate around fulcrum shaft 13, the movable shifting block 14 that is connected and installed with of one end, the other end of lever is pressed on the coding step of code wheel 11, its pressure is provided by elastic part 18, the calendar digital disk of being made by slide 16 is installed on the tubular axis of calendar gear, the clock and watch panel has window 17 to demonstrate week, day issue the entire mechanism capping.

See also Fig. 3, Fig. 4, Fig. 3 be among Fig. 1 code wheel 11 than detailed view, there are 48 teeth the outer ring among the figure, inside has 48 different steps of dividing by 48 round angles such as branch such as grade of radius to surround a closed level, a left side, right, 3 pits the darkest February in corresponding non-leap year is arranged at top, the February in a corresponding leap year of more shallow pit of bottom, the pit of in four quadrants all the other respectively corresponding 4,6,9,11 4 little months, the step of radius maximum is correspondence 3 respectively, 5,7,8,10,12,1 seven big months, obviously, then three non-leap years, the big solar month of 30 days in totally 48 month arranged rule to come out with the different step queueing discipline formal representation of the depth to this code wheel after with a leap year.Fig. 4 is the design proposal of another kind of code wheel, it does not consider the February in leap year, and 12 months rules of arrangement when only making even year is as the queueing discipline of coding step, so its only needs 12 teeth and 12 five equilibrium round angle steps, the corresponding February of the wherein the darkest step, all the other are according to pushing away.

The following describes the principle of work of mechanism.

Watch and clock movement drives 12 hour wheels 2 and rotates, 24 hour wheels 6 are followed its rotation, the moment is at hand the time when changing date zero, at first be that shifting block 7 promotes lever 12 direction motion to left down, suppose it is the end moment in February 28 non-leap year at this moment, position relation as schematically shown in Figure 1, then shifting block 14 just in time withstands the double wedge 4 on the calendar gear, in 24 hour wheels, 6 continuous rotating process, shifting block 14 promotes double wedge 4 continuously and turns over 3 days angular displacement, promptly stir calendar gear driven calendar digital disk and turn over 28 continuously, 29, till 30 days date reaches and shows 31, then stir a tooth of calendar gear again by shifting block 8, make window demonstrate 1, and moving tooth 5 is dialled simultaneously and is changeed code wheel 11 and turn over a tooth, make the probe of lever then be pressed in next month on the step of (this moment be March), so promptly finished the self-regulating process on date at the end of month February in non-leap year.Period before the end of month after 1 day, because double wedge 4 has left between the active region of shifting block 14, thereby the motion of lever does not play practical function, at the end of month in month in the solar month, because the probe of lever is pressed on the highest step of code wheel 11, make probe 14 be in the final position, thereby can not apply to dial to the calendar gear and transfer to usefulness, that is to say need not in month to adjust the date greatly by lever.When the solar month of 30 days promptly has only 30 days month, this moment, the lever probe was pressed on the corresponding more shallow pit step, make shifting block 14 only when arriving in 30th, just can touch and withstand double wedge 4, by the time when arrive constantly in 30 days end, shifting block 14 just can forward the calendar gear plectrum to 31 days position, and then, so finish the date at the little the end of month and adjust by 8 groups of positions that forward 1 to of shifting block.In like manner, when running into the February in leap year, the lever probe is on the corresponding step, makes shifting block 14 only just can stir later the adjustment that double wedge 4 was implemented the date on 29th.Put into Fig. 1 if replace code wheel shown in Figure 3 with code wheel shown in Figure 4; then be embodiment 2 schemes of the present utility model; obviously this scheme is because code wheel has only the step in 12 months corresponding non-leap years; thereby can not discern and adjust February in leap year; promptly can't show 29 automatically whenever February in leap year; this mechanism can be when non-leap year; leapt to later March 1 February 28; therefore when meeting the leap year in 3 years, still need date of manual correction; so this embodiment is not best, disclose with a kind of embodiment at this only serves as to provide contrast when selecting and expect protection to preferred plan.

It is comparatively complete that Fig. 5 discloses an additional function, embodiment 3 schemes that structure is more complete.Compare with Fig. 1, increased a third wheel 19 among Fig. 5, its effect is only for regulating the distance of 24 hour wheels 6 to the center, increased by one 24 hour wheel 21, increased a phases of the moon fluted disc 23, increased a monthly calendar gear 24, increase by one and dialled the sun 20, its effect is to be convenient to be provided with the adjustment date, in addition, for positional accuracy and the degree of stability that improves each gear, also increased ratchet 25 to ratchet 29 totally 5 ratchets, all parts are installed on the mounting dish 30, dialling the shifting block 9 of week going through gear has moved on on 24 hour wheels 21, also having a moving tooth 22 to be responsible for dialling on it changes phases of the moon fluted disc 23, and phases of the moon fluted disc has 59 teeth, the bimestrial fate in the corresponding lunar calendar, can stick the phases of the moon starry sky pattern of printing on it, relevant position at the clock and watch panel is provided with window, just can show the phases of the moon shape of every day visually, has in fact also shown the date of the lunar calendar approx; The monthly calendar digital disk is installed on the monthly calendar gear 24, the number that in the window of clock and watch panel, just can show month, in addition, 24 o'clock numbers and solar pattern labeling are attached on 24 hour wheels 6 number and sunrise sunset phenomenon in the time of in the window of clock and watch panel, just can showing 24 hours systems.Different among the shape of lever 12 and shifting block 14 and Fig. 1 as can be seen from Figure 5, its shape depends primarily on the design arrangement of its position and has randomness, but its function and the action principle in mechanism are duplicate.Mechanical work principle for present embodiment is basic identical by the principle of work that Fig. 1 narrated with the front, therefore needn't be repeated in this description.
