Abstract

The utility model discloses a dynamic globe. A free rotary time dial (6) is arranged at the upper end of a rotation shaft (9), and the time dial (6) is provided with 1-24 graduations which are arranged anticlockwise to represent 24 hours. An ecliptic plane ring (3) is provided with the signs of the date and the solar terms which are arranged clockwise, and the three points of the summer solstice, the midday 12 o'clock and the subsolar point are unified. The tail end of a revolution shaft which is also served as a date indicating pointer (4) forms an arrowhead shape. The problems of the existing tellurion are solved, such as the complicated structure, the inaccurate instructing time, etc. The dynamic globe has the advantages of simple structure, convenient use, accurate time instruction, etc., and can be widely used as a teaching aid, a gift and an ornament.

Description

Globe dynamically

Technical field the utility model relates to a kind of teaching purpose and the dynamically globe of present with process gift of being used for.

Background technology has " Instrument for surveying solar time and azimuth " and " space-time globe " in the prior art, and the two can demonstrate earth four seasons and round the clock, but the precision of " Instrument for surveying solar time and azimuth " is too high, so its structure is complicated; And the time of " space-time globe " expression is not accurate enough.

The summary of the invention the purpose of this utility model is to provide a kind of simple in structure, easy to use and accurate dynamically globe of instruction time.

In order to achieve the above object, the utility model provides following technical scheme: design a kind of dynamically globe, comprise base (1), (2) are enclosed in boundary round the clock, the axis of rotation (9) and terrestrial globe main body (5), the circular hole that the terrestrial globe main body (5) that can freely rotate respectively has by its Geophysical South Pole and arctic point is installed on the axis of rotation (9), the hollow shaft date pointer (4) of holding concurrently is fixedlyed connected with the ecliptic plane ring (3) of level, ecliptic plane ring (3) and the vertical circle circle (2) of demarcating round the clock links to each other, the below and the outer tube (8) of boundary circle (2) are fixedly linked round the clock, rotating shaft (7) is equipped with in the hold concurrently below of date pointer (4) of hollow shaft, rotating shaft (7) is inserted in the outer tube (8) of vertical fixing on base (1), this is the time dial plate (6) free to rotate of the globe top that is installed on the axis of rotation (9) upper end and is positioned at the sphere of terrestrial globe main body (5) dynamically, and time dial plate (6) has 24 hours 1～24 scale that is counterclockwise arrangement of expression.

The utility model technical scheme preferably is: have date and solar term sign on the ecliptic plane ring (3) by arranged clockwise, and summer solstice, high noon 12 scale marks and 3 unifications of subsolar point, the hold concurrently end of date pointer (4) of hollow shaft is an arrow shaped.Ecliptic plane 365 five equilibriums, each scale is represented one day; Date calibration is arranged in the direction of the clock, and table has the part solar term in season of 24 solar term simultaneously, summer solstice, high noon 12 scale marks and 3 unifications of subsolar point; The outer ring portion that is positioned at round the clock boundary circle rear side is represented night, and the outer ring portion that is positioned at the front side is represented daytime, and the hold concurrently end of date pointer (4) of hollow shaft makes the date indication more eye-catching for arrow shaped.

The utility model is to revolve around the sun and on the basis of earth's axis rotation rule at the research earth, allow any point of geostationary on its revolution orbit (counterclockwise), around 360 ° of hollow shaft clockwise (it is vertical with ecliptic plane to pass the earth's core) rotations, the expression earth revolved around the sun 1 year; Enclosing with boundary round the clock is the boundary, represents daytime towards the hemisphere of the sun, and the hemisphere of the sun is represented night dorsad; Represent ecliptic plane with the surface level that passes the earth's core; Be installed in 24 small time takings that had on the time dial plate (6) that rotates freely on the axis of rotation (9) of terrestrial globe arctic point position one day.

Operation instructions of the present utility model: the demonstration somewhere is the sun set/raise time of Beijing one day for example.Terrestrial globe is counterclockwise rotated around the axis of rotation, when sunrise is represented in Beijing when shady face turns to phototropic face, on the contrary expression sunset: at first rotate hollow shaft, make the date pointer point to this day; The rotation terrestrial globe makes Beijing be in the sunrise position then; Adjust the time dial plate again, 12 scale marks of 12 point～24 a place meridian and ecliptic plane are overlapped.At this moment, the warp of place, Beijing Dong8Qu drops on the position of time dial plate, be Beijing this day at sunrise between.In like manner, this day Pekinese's sunset time can be obtained, the local time of other local this moments in the world can also be obtained simultaneously.

Compared with prior art, the utlity model has simple in structure, easy to use and accurately instruction time etc. advantage.

Be description of drawings of the present utility model below the description of drawings:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is the plane design drawing of ecliptic plane ring (3);

Fig. 3 is the hold concurrently structural representation of date pointer (4) of hollow shaft.

Among Fig. 1～Fig. 3, the 1st, base, the 2nd, the circle of demarcating round the clock, the 3rd, ecliptic plane ring, the 4th, the hollow shaft date pointer of holding concurrently, the 5th, terrestrial globe main body, the 6th, time dial plate, the 7th, rotating shaft, the 8th, outer tube, the 9th, the axis of rotation.

By specific embodiment the utility model is described in detail below the embodiment:

With reference to Fig. 1,3, dynamically globe comprises base (1), (2) are enclosed in boundary round the clock, the axis of rotation (9) and terrestrial globe main body (5), the hollow shaft date pointer (4) of holding concurrently is fixedlyed connected with the ecliptic plane ring (3) of level, ecliptic plane ring (3) and the vertical circle circle (2) of demarcating round the clock links to each other, the below and the outer tube (8) of boundary circle (2) are fixedly linked round the clock, rotating shaft (7) is equipped with in the hold concurrently below of date pointer (4) of hollow shaft, rotating shaft (7) is inserted in the outer tube (8) of vertical fixing on base (1), time dial plate (6) free to rotate is installed on the axis of rotation (9) upper end, and time dial plate (6) has 24 hours 1～24 scale that is counterclockwise arrangement of expression; The hold concurrently end of date pointer (4) of hollow shaft is an arrow shaped.

With reference to Fig. 2, ecliptic plane ring (3) is rounded, has date and solar term sign by arranged clockwise on it, summer solstice, high noon 12 scale marks and 3 unifications of subsolar point, the figure bend partly is that dash area is represented night, and arrow is represented the solar light irradiation direction.
