End at described square Gui is equipped with two pieces of horizontal adjustment screws, its other end is equipped with one piece of horizontal adjustment screw, is bolted with the level-off nut above the horizontal adjustment screw.

Described sun altimeter is that the table and the sun are surveyed high protractor and closed the structure that is made as one, on the center line of this table, be provided with standard lines, the base of surveying high protractor at the sun is provided with light hole, the sundial pin is housed surveying high protractor in-plane perpendicular to the sun, this sundial pin is surveyed high protractor with the sun and is fixed on the table.

The beneficial effects of the utility model are: the function of corona, ancient Chinese sundial, level meter, sun altimeter, thermometer and compass etc. is synthesized one, the advantage that many usefulnessization are arranged, make the teacher can operate numerous teaching appliances easily, finish multinomial measurement at short notice, can improve students'interest in learning and the effect of giving lessons, be a kind of utensil that is suitable for natural science teaching usefulness.

[description of drawings]

Fig. 1 is a structural representation of the present utility model;

Among the figure: the square Gui of 1-, the 2-table, the 3-sun is surveyed high protractor, 4-sundial pin, 5-light hole, the 6-axis of swing, 7-holder, 8-level meter, 9-horizontal adjustment screw, 10-level-off nut, the 11-compass, 12-thermometer, 13-protractor, 14-length dimension table, 15-standard lines.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1, a kind of type multifunctional gnomon comprises the square Gui 1 as platform, at an end of described square Gui 1 two pieces of horizontal adjustment screws 9 is housed, its other end is equipped with one piece of horizontal adjustment screw 9, is bolted with level-off nut 10 above horizontal adjustment screw 9; End at square Gui 1 is equipped with table 2, is provided with 180 ° protractor 13 on 1 on the square Gui below table 2, and the extended line direction on 1 on the square Gui of 90 ° of directions of protractor 13 is provided with length dimension table 14; The other end at square Gui 1 is equipped with sun altimeter, the table 2 of this sun altimeter is connected with holder 7 on being fixed on square Gui 1 by an axis of swing that can swing 6, described sun altimeter is that the table 2 and the sun are surveyed high protractor 3 and closed the structure that is made as one, on the center line of this table 2, be provided with standard lines 15, the base of surveying high protractor 3 at the sun is provided with light hole 5, sundial pin 4 is housed surveying high protractor 3 in-planes perpendicular to the sun, this sundial pin 4 is surveyed high protractor 3 with the sun and is fixed on the table 2; It is improved in addition on the basis at ancient Chinese sundial that thermometer 12, level meter 8 and compass 11. type multifunctional gnomons are housed respectively in the both sides of square Gui 1, and the advantage of many usefulnessization is arranged, and finishes multinomial measurement at short notice.

Using method of the present utility model is:

The one, the level of regulating ancient Chinese sundial: earlier according to the level meter on the utility model broadside 8, the horizontal adjustment screw 9 on turn table 2 next door is till wide level; According to the level meter 9 on the long limit, the horizontal adjustment screw 9 of turn sun altimeter one end is till the level of long limit again.
