Description

Ultra-thin double-side clock

The utility model relates to timer, more relates to mechanical clock, refers more particularly to electronic quartz mechanical pointer clock.

The drive mechanism of prior art mechanical indicator clock all is identical, be that core device is in the clock dial center, pointer is directly installed on the movement output shaft, belong to coaxial coordination and connect transmission, though this bell structure mode is simple, do thinlyyer but limited the clock body, do not accomplish that more a movement drives two pairs of pointers simultaneously, is difficult to realize the ultra-thin type double face clock.

Purpose of the utility model provides a kind of novel transmission mechanism, promptly makes clock movement break away from the clock dial center by tapered gear and sleeve, realizes the slimming of clock body.

Another purpose is to adopt cone gear mechanism vertically to turn round to be transformed to the level running, and two pairs of pointers of a movement drive are realized two-sided clock.

Another purpose is that the intermittent duty that adopts photoelectric control to make the power source-motor of present technique often stop instantaneous work is realized little electric power energy consumption.

Below in conjunction with accompanying drawing the work system analysis is illustrated:

Accompanying drawing 1 is the utility model photoelectric control circuit schematic diagram;

Accompanying drawing 2 be the utility model continuously-the geneva motion mapping device;

Accompanying drawing 3 is the transmission of the utility model ratio and vertical-horizontal reverse mechanism;

Gear train is begun by Fig. 2, (3) are the common micromotor of power source of present technique among the figure, and gear (7) is housed on its output shaft, meshing gear (8), coaxially blanking disc (5) is housed and thumb wheel (9) is stirred sheave (10), simultaneously connection gear (11) transmission gear (12).

(12) coaxial connection among gear among Fig. 3 (13) and Fig. 2, gear (13) is engagement (14) on the one hand, and (14) connect (15) transmissions (16) and form 1 to 12 ratio transmission group, and other connects sleeve (23) with (16) for it.Be called clock movement by quartz oscillation, photoelectric control, thumb wheel sheave and four unit combination of ratio transmission.And by cone gear (17), (19) cone gear (18) of difference engaged transmission, (18 '), (20), (20 ') and the pointer (21) that is installed on it, (21 '), (22), the composition of (22 ') then is called clock dial, Zhong Xin realized by sleeve (23) with being connected with transmission of clock dial, in other words sleeve (23) makes clock dial break away from the clock movement center, this frame mode is invention main points of the present utility model theoretically, it is fundamental difference part with the prior art pointer clock, by (17) transmission (18), (18 ') and (19) transmission (20), (20 ') realizes vertical-level commutation, (18), pointer (22) when (18 ') installs, (22 '), and (20), (20 ') installs and divides pointer (21), and (21 ') is ultra-thin type double face clock specific implementation.

Accompanying drawing 1 is quartz oscillation and photoelectric control circuit, wherein (1) utilizes prior art crystal clock preferred circuit M5369, oscillation frequency is up to the number megahertz, main pulse signal when the high power frequency division is exported the standard in 30 seconds cycles, deliver to the startup trigger end S that utilizes prior art trigger 4013, motor start-up drives blanking disc (5), blanking disc has a light hole, go to the light place of luminotron (6) when this hole, irradiate light light-receiving tube (4) sends the shutoff trigger end R that trigger is delivered in pulse, and motor stops operating, the each startup of motor only drives blanking disc and returns and circle as seen from Figure 1, be to start once in per 30 seconds, the time of circling is one second, 1/30th when energy consumption only accounts for whole walk, realized the power supply of little electric power energy consumption, pointer belongs to step-by-step movement instruction time.

Claims (4)

1, a kind of ultra-thin type double face clock, it comprises quartz electronic oscillatory circuit (1), photoelectric control circuit (2), micromachine (3) and dialling by its driving by (9) and sheave (10), ratio driving gear set (13) is to (16), conical insert wheels (17) to (20) and the two pairs of pointers (21) that driven, (21 '), (22), (22 '), its feature is: by the sheave of micromotor driving, the clock movement that the ratio driving gear set is constituted by sleeve (23) with by conical insert wheels (17) to (20) two pairs of pointers (21), (21 ') (22), the clock dial mechanism that (22 ') constituted connects transmission with non-coordination coaxial manner.
