Abstract

The utility model discloses a chain type clock, which comprises a driving motor (8), a dial plate (1), an hour hand (3) and a minute hand (4), the chain type clock also comprises a driven main chain wheel (6), a sub-chain wheel (5) and a chain (7), and the dial plate (1), the hour hand (3), the minute hand (4) and the main chain wheel (6), the sub-chain wheel (5) and the chain (7) are in an identical visible scope. The chain type clock has advantages that the modeling is novel, the chain driving mechanism can be applied to the traditional pointer-type clock in an originative way, the chain type clock is rich in ornamental, the innervating effect is intense, and the chain type clock is full of interest when operating.

Description

The chain-type clock

Technical field

The utility model relates to Chronograph timepiece.

Background technology

Present analog timepiece is when driving walking of second hand, minute hand and hour hands simultaneously with motor mostly, and usually minute hand is arranged on the top of hour hands, and second hand is arranged on the top of minute hand.The function of above-mentioned analog timepiece is simple, and visual effect is relatively more dull, can not give people with more selection.

Summary of the invention

The purpose of this utility model provides a kind of chain-type clock, and initiative arrives the chain drive structure applications on traditional clock, and the decorative effect of existing novelty attractive in appearance can be given prominence to intellectual and interest again.

Technical solution of the present utility model is: a kind of chain-type clock, comprise drive motor, dial plate, hour hands and minute hand, it also comprises driven head sprocket, from sprocket wheel and chain, and described dial plate, hour hands, minute and head sprocket, be in the same visual range from sprocket wheel and chain.

Described head sprocket is driven motor-driven, drives chain with the constant speed shuttling movement.Cooperate traditional hour hands and minute hand instruction time, dynamic effect is strong, and head sprocket, from sprocket wheel and chain and be positioned on the front of dial plate is positioned at same visual range with hour hands, minute hand, and whole visual impact is bigger, is full of interest.

Described chain is provided with bar, is provided with the scale of instruction time on described dial plate.On dial plate, be provided with corresponding time scale, by the motion instruction time of bar.When being provided with many group sprocket wheels, chain, can regulate by the respective gears gear train and respectively organize the rotating speed of head sprocket, thereby can directly indicate with the rotation of chain the time, minute, second.By changing the ratio of gear of transmission gear, chain can be realized different movement velocitys, thus bar realize indication moon, week, the time, branch or the function of second.When being used to indicate, timesharing, can omit hour hands, minute hand.

On described chain, be provided with can ccontaining circular bead claw, bead moves to freely to fall behind the peak and carries out shuttling movement, has increased whole dynamic and interesting.

The utility model has the advantages that: modern design, initiative is applied to chain drive on traditional pointer clock, is rich in ornamentally, and dynamic effect is strong, is full of interest during operation.

Embodiment

Embodiment: consult Fig. 1 and Fig. 2, a kind of chain-type clock comprises dial plate 1, drive motor 8, hour hands 3 and minute hand 4, after wherein drive motor 8 is arranged on rear carrier plate 13, rotates instruction time by transmission shaft 11 drive transmission gears, 12 driving hour hands 3 and minute hand 4.Be provided with driven head sprocket 6 in dial plate 1 front portion, from sprocket wheel 5 and chain 7, and described dial plate 1, hour hands 3, minutes 4 are with head sprocket 6, be in the same visual range from sprocket wheel 5 and chain 7.

Described head sprocket 6 directly is driven motor 8 and drives, and associated transfer gear 12 is arranged in the cavity between dial plate 1 and the rear carrier plate 13, and this cavity can seal also and can open wide, to increase whole dynamic effect of decorating.Chain 7 is provided with bar 9, is provided with second accordingly with scale 10 on dial plate 1, can directly indicate second with the rotation of chain by the rotating speed of respective gears gear train adjusting head sprocket 5; When being provided with many group sprocket wheels, chain, can regulate by the respective gears gear train and respectively organize the rotating speed of head sprocket, thereby can directly indicate with the rotation of chain the time, minute, second.By changing the ratio of gear of transmission gear, chain can be realized different movement velocitys, thus bar realize indication moon, week, the time, branch or the function of second.When being used to indicate, timesharing, can omit hour hands, minute hand.

Embodiment 2: consult Fig. 3 and Fig. 4, on described chain 7, be provided with can ccontaining circular bead 15 claw 14, bead 15 moves to freely to fall behind the peak and carries out shuttling movement, has increased whole dynamic and interesting.The other technologies feature is identical with embodiment 1, does not repeat them here.

Above-listed detailed description is at the specifying of the utility model possible embodiments, and those embodiment are not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
