detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to Fig. 1-Fig. 3, the celestial globe of the present utility model comprises celestial sphere 1, base 2, time circle 3 and latitude disk 4. The celestial sphere 1 is divided into the southern celestial sphere and the northern celestial sphere. When the celestial sphere 1 rotates, the southern celestial sphere and the northern celestial sphere can rotate synchronously. The central part is provided with a date circle 11, and the celestial sphere 1 is marked with right ascension, declination, north and south celestial poles, celestial equator, Astronomy-related icons such as the ecliptic, stars, constellation images, etc., the date circle 11 is marked with a 1-year date scale, and the date scale corresponds to the ecliptic marked on celestial sphere 1 to the middle of celestial sphere 1, and is marked along the equator of celestial sphere 1 earned. The time circle 3 is movable and installed in the middle of the celestial sphere 1, and there is a protrusion 32 on the time circle 3. The time circle 3 is marked with a 24-hour time scale. In addition, the time circle 3 is also provided with a pointer that matches the position of the latitude disk 4. 31, that is, the pointer 31 can be set in conjunction with the latitude scale marked on the latitude disk 4.

The base 2 is provided with a groove 21, the size of the groove 21 matches the protrusion 32, and the protrusion 32 of the time circle 3 can be movably installed in the groove 21, that is, the celestial sphere 1 is movably installed on the base 2, so that the celestial sphere 1 can rotate together with the time ring 3 on the base. The latitude disk 4 is installed on the groove 21 of the base 2, and the latitude disk 4 is marked with a latitude scale of 90° north latitude and south latitude, and the protrusion 32 passes through the latitude disk 4, so that the pointer 31 is arranged on the surface of the latitude disk 4 , used to indicate the latitude scale. In addition, the protrusion 32 may not pass through the latitude disk 4, so that the pointer 3 is arranged on the back of the latitude disk 4, which is also used to indicate the latitude scale.

When the utility model is in use, the user can first find the corresponding date scale marked on the date circle 11 and the corresponding time moment marked on the time circle 3 according to the time and date of the celestial body to be observed, and then rotate the celestial sphere 1 in the horizontal direction, that is The date ring 11 on the celestial sphere 1 also rotates thereupon until the required date scale corresponds to the time scale, then stops rotating, and then the user finds the corresponding latitude marked on the latitude disk 4 according to the latitude of the observer, and then rotates Time circle 3, promptly rotates celestial sphere 1 with vertical direction, and now the pointer 31 on the time circle 3 also rotates thereupon, until pointer 31 rotates to corresponding latitude on latitude dish 4 and then stops rotating.
