Abstract

The utility model relates to a time display pointer clock, particularly a pointer clock which can display time clearly at night. The utility model comprises an hour hand lamp, a minute hand lamp, a second hand lamp, and a dial. The utility model is characterized in that pointer lamps with different depression angles are reflected on the dial forming light pointers with different lengths; light pointers are light formed by the direct reflection of the pointer lamps by the dial, so the brightness is large. The length of the light pointers which can be seen far away is determined by the angle formed by the irradiation of the pointer lamps to the dial. The utility model has the advantages of adjustable length of light pointers, clear light pointers at night, accuracy, strong contrast, simple structure, high reliability, etc.

Description

Light-pointer clock

The utility model is a kind of large-scale device, the particularly device when show night when apparent.

People wonder that the time sees clock and watch often, and existing apparent fashionable dress is equipped with pointer-type and numeral shows two kinds, and it is convenient that pointer-type has when reading than digital display type, and fast, characteristics such as Memorability is strong are so analog timepiece is useful in the public arena most.But night do not have the light condition under people just be difficult to see clearly clock and watch be some for addressing this problem, the common practice is that dial is added light illumination or be coated with luminescent material on pointer, problem when reading but large-scale pointer clock when showing outside hundreds of rice or a few km is just inapplicable with regard to solving, such as using light illumination, see on the too farsighted distance of brightness that clock and watch do not see pointer with regard to a slice light, too low with the luminescent material height, see on remote clock dial black blackened again do not see pointer.Also have general large-scale clock, that can not do is too big because clock do just can not solve the big quantity space of occupying of clock too greatly, the miniaturization of Zhong Xin, the difficult problem of technical barrier such as motor miniaturization and fund aspect.So limited the development of large-scale clockwise ultra-large type and lightness.

The purpose of this utility model is will provide a kind of to make the clock of pointer by light, no matter it can make people at night or can both be clear that the time on far distance daytime.

The purpose of this utility model is achieved in that major light with three high directivities is (as searchlight, laser lamp) replaces hour hands, minute hand and second hand are installed in and make the hour hands lamp on the finger axle, the irradiation light of minute hand lamp and second hand lamp and clock dial form the acute angle of three different angles, when light-pointer clock is opened, the pointer lamp of different angles forms the hour hands of different length on the very strong clock dial of diffuse reflection, minute hand and pin drive accurately work by the clock core.

The utility model because only need original watch and clock movement physical construction constant the basis on, replace three finger work by three major lights.So structure is simple especially; Owing to do not use original solid finger, so its movement is also littler than the movement of original great bell; Because different illumination and luminous paint method with light direct irradiation clock dial are so contrast is strong, in the time of reading in farther place.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the outboard profile according to the light-pointer clock that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises hour hands lamp (1) minute hand lamp (2) second hand lamp (3), and they are installed in hour hand axle respectively by the different angles of depression, on minute hand shaft and the second hand axle.

When light-pointer clock is worked, each pointer lamp sends An Intense Beam of Light and impinges upon on the clock dial (4), the angle minimum that light beam that second hand (3) penetrates and clock dial (4) form, so shadow is the longest, form second hand, minute hand lamp (2) shadow that angle is big slightly is shorter slightly than the shadow of second hand lamp (3), forms minute hand, hour hands lamp (1) shadow of angle maximum is the shortest, forms hour hands.

Claims

1, large-scale device when apparent, the light-pointer clock when particularly providing show night, this clock has clock dial (4) that needle pivot is arranged therebetween, it is characterized in that being installed with respectively on the needle pivot hour hands lamp (1) minute hand lamp (2) and second hand lamp (3).

2, according to claim: the described light pointer of the different length that hour hands lamp (1) minute hand lamp (2) and second hand lamp (3) irradiation are come out that it is characterized in that all reflects on clock dial (4).

3, according to claim 1,2 describedly is characterized in that the light that hour hands lamp (1) minute hand lamp (2) and second hand lamp (3) are shot downward and the angle of clock dial are acute angles.
