Abstract
The utility model provides a simple teaching demonstration board of a thermometer, which relates to a teaching demonstration device and is simple in structure. The simple teaching demonstration boardof a thermometer comprises a vertical board, and is structurally characterized in that the vertical board is equipped with a scale board with centigrade and fahrenheit scales, fixing sleeves are vertically arranged on the scale board, and a strip-shaped slip sheet is arranged inside the fixing sleeves.
Description
Technical field:
The utility model relates to a kind of teaching demonstration device, more particularly, relates to a kind of simple and easy teaching demonstrating board of thermometer.
Background technology:
Temperature is the physical quantity that is used for representing the cold and hot degree of object; Thermometer is the instrument of probe temperature; The unit of metering temperature be divided into degrees Fahrenheit and degree centigrade.In physics teaching in secondary school, adopt common thermometer to carry out teaching demonstration, because its fluid column is thin, whole less, be not easy to observation of students; And if the numerical value change that thermometer is shown is obvious, required external condition also is not easy to reach; In addition, for the unit of metering temperature, the student easily obscures relation between the two.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of simple and easy teaching demonstrating board of thermometer simple in structure is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises riser, its structural feature is that riser is provided with and has scaleplate Celsius, the Fahrenheit thermometer, scaleplate vertically is provided with fixed cover, is provided with the bar shaped slide plate in fixed cover.
The beneficial effects of the utility model:
Because the utility model riser is provided with and has scaleplate Celsius, the Fahrenheit thermometer, scaleplate vertically is provided with fixed cover, is provided with the bar shaped slide plate in fixed cover; So it is simple in structure.During demonstration, the bar shaped slide plate has replaced the tiny fluid column of thermometer commonly used, makes the more convenient observation of student; And, can regulate variation of temperature as required arbitrarily, in addition, can also clearly illustrate the relation between Celsius, the Fahrenheit temperature unit.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises riser 4, and riser 4 is provided with has scaleplate 3 Celsius, the Fahrenheit thermometer, and scaleplate 3 vertically is provided with fixed cover 2, is provided with bar shaped slide plate 1 in fixed cover 2.
Fixed cover 2 is four.
