Abstract
The utility model relates to a kind of Metal Deformation and varies with temperature demonstration device, comprise heating plate, beverage container, laser lamp, connecting link, tinsel firmware, tinsel, tinsel slot, thermometer, it is characterized in that: described heating plate and beverage container are tightly connected, thermometer is attached to the inner side of beverage container, tinsel slot is vertically fixed on the centre of heating plate, the opening that described laser lamp head is movably fixed to beverage container is disclosed on wall, afterbody is fixed on connecting link, connecting link uses tinsel firmware to be flexibly connected with one end wiry, the other end wiry inserts in tinsel slot.After heating plate heating liquid, by the height of the real-time displays temperature of thermometer, variation with temperature wiry causes the change of connecting link, connecting link drives laser lamp change, laser lamp luminous point in white wall also changes thereupon, the enlargement factor of tinsel deformation can realize by regulating the distance of the utility model and white wall, and demonstrating effect is obvious.
Description
Technical field
The utility model relates to a kind of physical teaching aid, is specifically related to a kind of Metal Deformation and varies with temperature demonstration device.
Background technology
Time student understands the characteristic of metal heat-expansion shrinkage, generally heat on spirit lamp with a tinsel measuring certain length at present, again the tinsel after heating is measured length, to show the situation of tinsel expansion deformation, some adopts " copper ball demonstrating expansion on heating and contraction on cooling device ", and former data change greatly, latter cannot provide data, also some adopts pointer-type, but sensitivity is not high, and can not observe the situation of temperature and tinsel deformation at any time.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of Metal Deformation and varies with temperature demonstration device.
The utility model is realized by following technological means: a kind of Metal Deformation varies with temperature demonstration device, comprise heating plate, beverage container, laser lamp, connecting link, tinsel firmware, tinsel, tinsel slot, thermometer, it is characterized in that: described heating plate and beverage container are tightly connected, thermometer is attached to the inner side of beverage container, tinsel slot is vertically fixed on the centre of heating plate, the opening that described laser lamp head is movably fixed to beverage container is disclosed on wall, afterbody is fixed on connecting link, connecting link uses tinsel firmware to be flexibly connected with one end wiry, the other end wiry inserts in tinsel slot.
During concrete use, one end wiry is flexibly connected with connecting link by tinsel firmware, the other end inserts in tinsel slot, open laser lamp power supply, luminous point is projected in white wall and open laser lamp power supply, luminous point is projected in white wall, liquid is added in beverage container, connect the power supply of heating plate, the change of Real Time Observation fluid temperature, when reaching required temperature, close the power supply of heating plate, at this time the deformation with temperature wiry causes the change of connecting link by the flexible connection of tinsel firmware, connecting link drives laser lamp change, laser lamp luminous point in white wall also changes thereupon, the enlargement factor of tinsel deformation can realize by regulating the distance of the utility model and white wall, demonstrating effect is obvious.
The utility model structure is simple in addition, manufacturing cost and use cost all lower, easy to manufacture, very easily promote.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; under the ambit not departing from the protection of the utility model aim, can also make the concrete conversion of a lot of form, these all belong within protection domain of the present utility model.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model
In figure: 1-laser lamp, 2-heating plate, 3-tinsel, 4-connecting link, 5-tinsel firmware, 6-thermometer, 7-tinsel slot, 8-beverage container.
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be described in further detail:
As shown in FIG., a kind of Metal Deformation varies with temperature demonstration device, comprise heating plate, beverage container, laser lamp, connecting link, tinsel firmware, tinsel, tinsel slot, thermometer, it is characterized in that: described heating plate and beverage container are tightly connected, thermometer is attached to the inner side of beverage container, tinsel slot is vertically fixed on the centre of heating plate, the opening that described laser lamp head is movably fixed to beverage container is disclosed on wall, afterbody is fixed on connecting link, connecting link uses tinsel firmware to be flexibly connected with one end wiry, the other end wiry inserts in tinsel slot.
During concrete use, one end of tinsel (3) is flexibly connected with connecting link (4) by tinsel firmware (5), the other end inserts in tinsel slot (7), open laser lamp (1) power supply, luminous point is projected in white wall, liquid is added in beverage container (8), connect the power supply of heating plate (2), by the change of thermometer (6) Real Time Observation fluid temperature, when reaching required temperature, close the power supply of heating plate (2), at this time the deformation with temperature of tinsel (3) causes the change of connecting link (4) by the flexible connection of tinsel firmware (5), connecting link (4) drives laser lamp (1) change, laser lamp (1) luminous point in white wall also changes thereupon, the enlargement factor of tinsel deformation can realize by regulating the distance of the utility model and white wall, image, intuitively, phenomenon is obvious.
