Description

Semi-circumference scale clock

Technical field

The utility model relates to a kind of clock.

Background technology

In the daily life that applies to us that clock is a large amount of, be carved with scale on the dial plate of circumferential, dial plate is provided with pointer, and pointer comes the demonstration time by driving gear drives according to pointer indication scale.In the prior art, dial plate is a whole circumference, hour hands are represented 12 hours around one week of scale, minute hand is 60 minutes (just 1 hour) around one week of scale, second hand is 60 seconds (just 1 minute) around one week of scale, driven wheel has mechanical type driving, electronic type driven wheel, makes gear make hour hands, minute hand, second hand by above-mentioned rotational speed by different ratio of gear is set.It is exactly decoration function that existing clock also has the important effect of another one, the major part that clock shows is a dial plate, in order to strengthen decorative effect, the clock manufacturer is provided with exquisite pattern on dial plate, but the time showing effect that can have influence on clock after the pattern on certain program is set on dial plate, makes that the dial plate as main display surface seems mixed and disorderly.

Summary of the invention

The purpose of this utility model is to provide a kind of can know the demonstration time, can carry out the semi-circumference scale clock of fine decoration simultaneously to dial plate.

The utility model is achieved through the following technical solutions:

A kind of semi-circumference scale clock comprises the dial plate that has scale, is provided with pointer on dial plate, and pointer is by driving gear drives, and each described pointer respectively has a pointer end with respect to the pointer shaft both sides; Described scale is distributed on the circumference of described dial plate one side, is provided with shadow mask at the opposite side of described scale, and shadow mask to small part is blocked the pointer end of this side.

Scale in the utility model only is located at a wherein side of dial plate circumference, shadow mask can be provided with decorative pattern or other device for nontransparent or translucent on it, as being used for displaying calendar, week or the like, can play better decoration function, and not influence the demonstration of clock.Described shadow mask can be positioned at arbitrary orientation of dial plate, as above half side, down half side, a left side is half side, right half sidely all can.

Further improvement of the utility model is:

Two pointer ends of each described pointer are with respect to the pointer shaft symmetry.This structure can conveniently be processed, and two pointer end symmetries can make pointer keep balance, in order to avoid influence the precision of pointer.

Described dial plate half that a graduated side circumference is whole dial plate circumference that distribute.Scale is distributed on the semi-circumference, and in when design, the rotating speed of each pointer can get final product for half of former rotating speed, and this structure is beneficial to the design of the driven wheel of pointer.

Described shadow mask is provided with decorative pattern; Can have decoration on the described pointer; Also can be provided with decorative pattern in the above scale one side of described dial plate.This structure can improve the aesthetic property of clock, and the mutual corresponding trade-off effect of three is better; As dial plate is last half side, and the decorative pattern on it is a sky, and decoration is a star, and shadow mask is positioned at half side down, and the decorative pattern on it is the ocean, and each decorative pattern, the mutual correspondence of decoration form as a whole.

Described dial plate is provided with the outer cover that covers dial plate, and described shadow mask is located on this outer cover.To be positioned at dial plate one side that is provided with scale be transparent to outer cover as described, and opposite side is nontransparent shadow mask.

The area of described shadow mask is not more than half of (being less than or equal to) dial plate area.Shadow mask to small part is blocked a side of described pointer.Because of described pointer has two pointer ends, hour hands, minute hand, second hand be totally three pointers, six pointer ends, seems mixed and disorderly, when pointer is not indicated, with shadow mask it blocked, and makes dial plate seem succinct.

Pointer can be for a plurality of, be hour hands, minute hand, second hand, its rotating speed is half of pointer rotating speed in the prior art, be the rotating speed of hour hands, minute hand, second hand be respectively per 360 degree/24 hours, 360 degree/2 hours, 360 degree/2 minutes, just hour hands are represented 12 hours around the scale half cycle, minute hand is 60 minutes (just 1 hour) around the scale half cycle, and second hand is 60 seconds (just 1 minute) around the scale half cycle.The rotating speed reduction of pointer is had multiple mode: install reduction gearing additional on the basis of prior art driven wheel, the speed ratio of reduction gearing is 0.5; Also the number of teeth of driving gear can be kept to half of the prior art number of teeth; Or the number of teeth of follower gear doubled; Also can redesign the ratio of gear of each gear, as long as the rotating speed of each pointer is above-mentioned rotating speed.

To sum up, the utility model has the advantages that:

1, the demonstration of clock has only utilized half of dial plate in the utility model, and second half can be used for showing or other content being set, and makes the clock clear display, the good decorating effect of clock.

2, the decorative pattern on the shadow mask, the decoration on the pointer, the decorative pattern on the dial plate can improve decorative effect, and can be corresponding mutually, become one.

Embodiment

Embodiment one:

See also Fig. 1 to Fig. 3, present embodiment comprises the dial plate 2 that has scale 1, and scale 1 is distributed in a side of dial plate 2, and scale 1 shared circumference is half of dial plate 2 circumference.Be provided with hour hands, minute hand, second hand three root pointers 3 on dial plate 2, pointer 3 is by driving gear drives.Outer cover 4 covers dial plate 2, and the side that outer cover 4 is positioned at scale 1 is transparent, and opposite side is nontransparent shadow mask 7.The area of shadow mask 7 is equal to or less than half of dial plate 2 areas, and shadow mask 7 is provided with decorative pattern; Each pointer 3 respectively has a pointer end with respect to pointer shaft 5 both sides, and pointer 3 both sides have decoration 6 with respect to pointer shaft 5 rotational symmetry on the pointer 3.The rotating speed of driven wheel is half of prior art rotating speed, promptly the rotating speed of hour hands, minute hand, second hand be respectively per 360 the degree/24 hours, 360 the degree/2 hours, 360 the degree/2 minutes.

Embodiment two:

See also Fig. 4, Fig. 5, the difference of present embodiment and embodiment one is: do not have outer cover 4 on the dial plate 2, directly the side at dial plate 2 is provided with shadow mask 7, and shadow mask 7 is provided with decorative pattern, and shadow mask 7 parts are blocked pointer shaft 5.All the other structures are identical with embodiment one.
