Abstract

The utility model relates to an inlaid type calendar mechanism for quartz clocks, which provides the design of a calendar mechanism with a simple and ingenious structure for quartz clocks. Three part assemblies are additionally arranged on a general quartz clock movement, and an annular groove is arranged on a main clamping plate so that the inlaid type calendar mechanism is formed. The calendar mechanism not only can simultaneously display dates and weeks as a dual calendar, but also can only display dates as a single calendar. In addition, the calendar mechanism does not thicken a clock movement, the adopted part assemblies can be produced through injection molding processes, and the process and the assemblage are very convenient.

Description

Inlay calendar mechanism for quartz clock

Embedded crystal clock calendar mechanism belongs to the time keeping instrument field.

The utility model provides a kind of design of crystal clock calendar mechanism of exquisiteness simple for structure.On the basis of general quartz clock movement, increase by three spare parts, and on bottom plate, offer an annular groove, promptly constitute embedded calendar mechanism.This calendar mechanism not only can show date and week simultaneously as day-date, also can show date as singly only going through.In addition, this calendar mechanism does not increase the thickness of movement, and the spare part that is adopted can both be produced with Shooting Technique, and processing and assembling are all very convenient.

Structure of the present utility model is shown in figure (1):

(1)---calendar hour setting wheel (2)---calendar main wheel

(3)---week disk (4)---date disc

(5)---location fork (6)---bottom plate

(7)---date-indicator window

Calendar hour setting wheel (1) adds an axle tooth and constitutes on common hour setting wheel, its detailed structure is shown in figure (2).This be one by hour setting wheel wheel sheet (8), the gear of hour setting wheel axle tooth (9) and hour setting wheel axle tooth (10) composition.The modulus of hour setting wheel axle tooth (10) is 0.3, has 6 teeth.With hour setting wheel axle tooth (10) engagement be calendar main wheel (2), its detailed structure is shown in figure (3), wherein (11) take turns sheet for the calendar main wheel, (12) are calendar main wheel impeller fork.The modulus of calendar main wheel wheel sheet (11) is 0.3, and the number of teeth is 48 teeth.35 teeth are arranged on the interior circle of week disk (3), and cylindrical and date disc (4) are made transition fit.The location fork (5) of making one with bottom plate (6) is a whippy locating device, and its head springs into the between cog of week disk (3), can give week disk (3) location, can prevent that again week disk (3) from reversing in the counterclockwise direction.Week disk (3) and date disc (4) are done as a whole, put into the groove of bottom plate (6), are slidingly matched with groove.Date-indicator window (7) is out a hole on clock face, and the week disk (3) and the date disc (4) of below aimed in the hole.

The utility model is operation like this:

Calendar hour setting wheel (1) per hour rotates a circle, and drives calendar main wheel (2) and rotates a circle in per 24 hours.The calendar main wheel impeller fork (12) that is fixed on the calendar main wheel (2) was dialled a date disc (4) in per 24 hours, made date disc (4) and week disk (3) turn over the angle of a tooth simultaneously along clockwise direction.Date disc (4) is printed on the symbol in date and week respectively with the surface of week disk (3), corresponding to 35 teeth, has five groups of identical week symbols on the week disk (3), and every group contains seven symbols on Monday to Sun..One group of date symbol is arranged on the date disc (4), constitute by 1 to 31, its arrangement mode is identical with the arrangement mode of date symbol.Like this, week disk (3) and date disc (4) turned over a tooth in per together 24 hours, just occur in the date-indicator window (7) one group of date and week symbol.This cover calendar mechanism will be adjusted once in every month.During adjustment, if stir date disc (4) clockwise, week disk (3) and date disc (4) just rotate simultaneously, the usefulness that can regulate date and week simultaneously.When stirring date disc (4) counterclockwise, fork (5) withstands and can not rotate because week disk (3) is positioned, so up to external force during greater than the stiction between the same week disk of date disc (4) (3), date disc (4) just begins independent rotation, so just can regulate the relation in date and week.If only need show date, then further simplified structure is made one with date disc and week disk, only needs 31 teeth on the interior circle of dish, and the surface stamps 1 to 31 date symbol, and other structures are all constant.

Claims

1, a kind of embedded calendar mechanism that is used for quartz analog clock, it is by calendar hour setting wheel (1), calendar main wheel (2), week disk (3), date disc (4), location fork (5), bottom plate (6), date-indicator window (7) is formed, it is characterized in that: the modulus of hour setting wheel axle tooth (10) is 0.3, and the number of teeth is 6 teeth, and the modulus of calendar main wheel wheel sheet (11) is 0.3, the number of teeth is 48 teeth, and 35 teeth are arranged on the interior circle of week disk (3).The interior circle of the cylindrical of week disk (3) and date disc (4) is made transition fit.

2, embedded calendar mechanism according to claim 1, when singly going through mechanism's use, week disk (3) and date disc (4) are merged into a dish, and 31 teeth are arranged on the interior circle of dish.
