Abstract

The utility model relates to a bidirectional block, which consists of a clock plate (1) and pointers (2). A center shaft (3) is disposed at the center position of the clock plate (1), one end of each pointer (2) is connected onto the center shaft (3), and both the front surface and reverse surface of the clock plate (1) are provided with the pointers (2) and further provided with scales. Both the front surface and reverse surface of the clock plate are provided with the pointers and the scales, and then the pointers can rotate towards two opposite directions simultaneously.

Description

Bidirectional clock

Technical field

The utility model relates to a kind of clock, specifically is meant the clock of a kind of double-sided display type time.

Background technology

The primitive man comes judgement time with the luminosity of sky change in color, the sun.The ancient human finds to distinguish constantly according to the shadows cast by the sun orientation on the corona in natural production.Came writing time with water clock or hourglass afterwards.At the Eastern Han Dynasty, Chinese Zhang Heng has made the commentaries on classics armillary sphere that leaks, and with gear train celestial globe and timing water clock is tied, and water clock drips and promotes celestial globe and rotate equably, just circles in one day, becomes mechanical clock the earliest.1797, American Yi Laiteli (Eli Terry) obtained the patent right of a clock.He is regarded as the first ancestor of U.S.'s timepiece industry.

Since clock and watch were born, people were devoted for years to the precision of measuring in the raising time, did not but note the rotation direction of research hour hands.All " it is left-handed, and ground is right moving ", promptly left hand helix is as clockwise direction for hour hands.The human lives and is being subjected to the influence of single like this sense of rotation for a long time in such environment.

Earth rotation is a natural standard time clock.The rotation and the revolution of the earth have constituted time system.Clock is to be used for representing nature machine constantly.It and Human's production, life are accompanied morning and evening, and its importance is self-evident.Its sense of rotation also should compliant motion the natural law.

The utility model content

Technical problem to be solved in the utility model provides a kind of bidirectional clock, and the dial plate tow sides are equipped with pointer and scale, can realize simultaneously that pointer walks about to opposite both direction.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: bidirectional clock, mainly form by dial plate and pointer thereof, be provided with central shaft in described dial plate center, described pointer one end is connected on the central shaft, in order to make the clock and watch both sides can show the time simultaneously, tow sides at described dial plate are equipped with pointer, and are equipped with scale at the pros and cons of described dial plate.

Further, described pointer comprises hour hands, minute hand and second hand, and described hour hands, minute hand and second hand are connected on the central shaft.

Move according to the natural law in order to control hour hands, minute hand and second hand, described central shaft is provided with mechanical driving device.

To sum up, the beneficial effects of the utility model are: the tow sides at dial plate are equipped with pointer and scale, and pointer all is connected on the same central shaft, rotate along the left hand helix direction at pointer of dial plate, and another side promptly is to rotate along the right-handed helix direction.Earth rotation is a natural standard time clock, see on the Northern Hemisphere, the left hand helix direction is clockwise direction, and from the Southern Hemisphere, the right-handed helix direction just should be a clockwise direction, and the double-edged hour hands rotating rule of this bidirectional clock satisfies this natural law just, and it is not only laborsaving that movement direction of object has been complied with the direction of earth rotation on the earth, and it is light that human body also can be felt.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

Embodiment

As shown in Figure 1, on the Northern Hemisphere, it is to rotate towards the right-handed helix direction that the mankind can observe the earth.Yet in the Southern Hemisphere, it is towards the rotation of left hand helix direction that the mankind but can observe the earth.Though the sun of seeing in south, the Northern Hemisphere all is to rise eastwardly, fall from the west, it is towards diametrically opposite direction rotation with respect to earth two ends.So there is both direction in the rotation of the earth simultaneously with revolution.The shadows cast by the sun that corona is gone up on the Northern Hemisphere move according to the left hand helix direction.The shadows cast by the sun of corona on the Southern Hemisphere move according to the right-handed helix direction.So there is both direction simultaneously in tellurian shadows cast by the sun.The direction that rotatablely moves should be consistent with the direction of revolution with the rotation of the earth, so the Northern Hemisphere is the right-handed helix direction clockwise, the Southern Hemisphere be the left hand helix direction clockwise.

As shown in Figure 2, this bidirectional clock mainly is made up of dial plate 1 and pointer 2 thereof, is provided with central shaft 3 in described dial plate 1 center, and described pointer 2 one ends are connected on the central shaft 3, is equipped with pointer 2 at the tow sides of described dial plate 1; Pros and cons at described dial plate 1 is equipped with scale.

As shown in Figure 3, described pointer 2 comprises hour hands, minute hand and second hand, and described hour hands, minute hand and second hand be connected on the central shaft 3, and described central shaft 3 is provided with mechanical driving device.

It is not only laborsaving that movement direction of object has been complied with the direction of earth rotation on the earth, and it is light that human body also can be felt; Otherwise the direction of movement direction of object is disloyal earth rotation is not only required great effort, and it is nervous that human body also can be felt.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, to any simple modification, equivalent variations that above embodiment did, all fall within the protection domain of the present utility model on every foundation technical spirit of the present utility model.
