Abstract

The utility model relates to the improvement of the structure of the existing pointer type crystal clock and watch. The front plate in the front and back plates for fixing the tooth gear driving wheel system in the existing cores of clocks and watches is removed and replaced by a clock dial. The shafts at all levels of the gear driving wheel system adopt suspension arm shafts with stop resistance realized through the clock dial. Accordingly, the clock dial has dual functions of an ordinary clock dial as well as the front plate in the core of the clock and watch. Because the clock structure is simplified and the axial dimensions of the clock and watch are compressed, the utility model achieves the goal of further thinning and miniaturizing pointer type crystal clocks and watches.

Description

A kind of pointer quartz clock and watch

The utility model relates to a kind of pointer quartz clock and watch.

Clock and watch are produced the existing semicentennial history in China, development along with microelectronics industry, the quartz clock technology has had very big progress, product is brought in constant renewal in, new product emerges in an endless stream, but the renewal of product does not in the past often relate to the basic structure of clock and watch, with regard to the basic structure of present watch and clock movement, remain by forward and backward two clamping plates or the clamping plate more than two, the centre is loaded onto the gear drive train and is formed, as shown in Figure 1, existing this clock and watch structure is unfavorable for further slimming, the miniaturization of pointer quartz clock and watch.

The purpose of this utility model is the improvement to existing quartz analog clock list structure, by simplifying the clock and watch structure, particularly simplifies the structure of watch and clock movement, realizes further slimming, the miniaturization of pointer quartz clock and watch.

The purpose of this utility model is achieved in that a kind of pointer quartz clock and watch, is made of movement, casing, surface, pointer, and movement comprises the forward and backward clamping plate of gear drive train and fixed gear train.Front plate with the fixed gear train in the described movement removes, form movement by surface, rear plate, gear drive train, the axle that links gears at different levels in the gear tradition train adopts cantilevered axle, one end of cantilevered axle is fixed on the rear plate, the axial retaining that gear wheel is fastened end is propped up by the inner plane on surface, and there is a pilot hole that can make location, gear drive train center at the center on surface.

The utility model is owing to improve the structure of pointer quartz clock and watch movement, make the surface both play the effect on common clock and watch surface, play simultaneously the effect of front plate in the watch and clock movement again, thereby can save requisite front plate in the existing watch and clock movement, compressed the axial dimension of clock and watch, not only help clock and watch to more slimming, miniaturization development, and be fit to the demand of people again slim clock and watch.

Below in conjunction with accompanying drawing structure of the present utility model is specifically described:

Fig. 1 has quartz analog clock list structure synoptic diagram now.

Fig. 2 the utility model quartz analog clock list structure synoptic diagram.

Among Fig. 1, the 1st, front plate, the 2nd, rear plate, the 3rd, the surface, the utility model as shown in Figure 2, gear drive train in the pointer quartz clock and watch movement directly is contained between rear plate 2 and the surface 3, the axle 5 that links gears at different levels is cantilevered axle, one end of axle is fixed on the rear plate 2, rotor 4 is housed respectively on each, third wheel 6 and hour setting wheel 9, the lower end of the central shaft 7 of minute wheel 8 is by the center pit supporting of rear plate 2, and minute hand 12 is contained on the central shaft 7 of minute wheel 8, upper end at the central shaft 7 of minute wheel 8 is with hour wheel 10, hour hands 11 are contained on the hour wheel 10, and hour wheel 10 is by the center pit supporting on surface 3, and the inner plane on surface 3 plays again rotor 4, third wheel 6, the top axial retaining effect of hour setting wheel 9.When the driving pulse in 30 seconds an of interval of integrated circuit output in the watch and clock movement affacts on the stepper motor 13, deceleration by rotor 4, third wheel 6 and minute wheel 8, minute hand 12 is done the indication in 30 seconds on the scale value on surface 3, hour hands 11 are also done corresponding angle indication on the scale value on surface 7 under the transmission of hour setting wheel 9, hour hands 10.

The fixing mode that can adopt straight forming on plastic clamping plate of axle 5 in the above-mentioned watch and clock movement in the gear drive trains at different levels and rear plate 2.

Claims

1. pointer quartz clock and watch are made of movement, casing, surface, pointer, and described movement comprises forward and backward clamping plate (1), (2) of gear drive train and fixed gear train, it is characterized in that:

Front plate with the fixed gear train in the described movement removes, and forms movement by surface (3), rear plate (2), pinion unit;

The axle (5) that links gears at different levels in the described gear drive train adopts cantilevered axle, and an end of cantilevered axle is fixed on the rear plate (2), and the axial retaining that described gear wheel is fastened end is propped up by the inner plane of surperficial (3);

There is a pilot hole that can make location, gear drive train center at the center on described surface (3).

2. pointer quartz clock and watch according to claim 1 is characterized in that the fixing mode that can adopt straight forming on plastic clamping plate of axle (5) and rear plate (2) in the described gear drive train.
