Abstract
The utility model provides a gas thermal expansion experimental instrument relating to the fields of scientific experimental devices and teaching and solves problems that corresponding experimental equipment is in shortage currently and prior experimental equipment is single in function. The gas thermal expansion experimental instrument includes a pedestal and a bottom body fixed on the upper end of the pedestal. A bottom cover is covered on the upper end of the bottom body. The bottom cover is provided with an air hole and an air hole plug. A transparent thin pipe is also inserted into the center of the bottom cover. A funnel is arranged on the upper end of the transparent thin pipe fixedly. The lower end of the transparent thin pipe is inserted into a liquid container arranged in the bottom body. The liquid container contains colored liquid. The gas thermal expansion experimental instrument provided by the utility model is made of easy-to-get items such as plastic pen rods, plastic bottom caps and the like. The swing pendulum experimental instrument is simple in structure and easy to manufacture, so that the gas thermal expansion experimental instrument is suitable for manufacturing manually and manufacturing at home by students.
Description
Technical field:
The utility model relates to scientific experiment device and teaching field, is specifically related to a kind of gas thermal expansion experiment instrument.
Background technology:
At present, be used for most experimental provision complex structure of teaching, function singleness, the scope of application are wideless.And almost the basic principle of physics study is not tested and the experimental provision of making on the market, causing rigidly connecting tactile physical students in middle and primary schools can't be to the clear understanding of basic physics knowledge, add some theoretical property concepts physically, if do not explained orally analysis, be difficult to allow those students of begining to learn understand, thereby make most students forfeiture learning interest.Simultaneously, most scientific experiment instrument all can only use as teaching, and most of times all can only be placed in the storehouse, can not as ornaments or handicraft puts on display.So generally can not enter into family, the student contacts the chance of these scientific experiment instruments will be seldom.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of gas thermal expansion experiment instrument is provided, solve to lack corresponding experiment equipment at present, and the problem of existing experiment equipment function singleness.These experiment instrument plastic artsization, make experiment instrument change the scientific technology product into, and kept the little experiential function of the original physics of experiment instrument, can do experiment, can enter family again, become the ornament in the family room, both increased the science atmosphere of family, beautify the environment again, satisfied the right fashion requirement of people, also can be used as extracurricular science toy simultaneously.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of gas thermal expansion experiment instrument, it is characterized in that, comprise base and the bottle that is fixed on the base upper end, bottle cap is stamped in the bottle upper end, bottle cap is provided with pore and air plug, and a transparent thin tube is also inserted at described bottle cap middle part, and described transparent thin tube upper end is set with funnel, insert in the liquid container that is arranged in the bottle described transparent thin tube lower end, is loaded with band look liquid in the liquid container.
Described base is plastic bottle closure, and transparent thin tube is transparent pen core, and described funnel and liquid container are made for a tail-hood, and material is easily got, and cost of manufacture is lower.
Described band look liquid is the red ink of dilution.
The use of experiment instrument: grasp plastic bottle body, cross and red ink can occur and goes up from transparent thin tube, it is more long to hold bottle time, liquid level rises more highly, water in the liquid container can all rise in the funnel, and water became decline after hand left bottle, got back in the liquid container again.Opening air plug more beyond the Great Wall can be from newly doing experiment.
The physical principle that experiment instrument relates to: gas expands with heat and contract with cold.Experiment instrument is safety in the process of using, test, playing, and does not have harm hidden danger.
The beneficial effects of the utility model are:
Gas thermal expansion experiment instrument is to be material with easy taking artical product such as plastic penholder, plastic bottle closures, is made.Experiment instrument is simple in structure, make easily, thereby suitable student starts to make and the making of being in.The lines of experiment instrument design are beautiful clean, and color grace, outward appearance are dazzled extremely, and experimental apparatus is art up, become that table is gone up, the ornament in the cupboard, and the purposes of experimental apparatus obtains expanding, and becomes the novel products of practicality.When experiment instrument used as the little experimental apparatus of physics, experimental phenomena is directly perceived, vivid and interesting obviously, and it is clear understandable that physical principle embodies.When experiment instrument uses as extracurricular toy, can allow the student have fun, thereby embody the teaching idea of in playing the middle school, learning, playing, allow the student in playing, go experiment to probe into physical principle, disclose the science reason in the life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with specifically illustrating and embodiment, further set forth the utility model.
As shown in Figure 1,
A kind of gas thermal expansion experiment instrument, comprise base 7 and the bottle 6 that is fixed on base 7 upper ends, bottle cap 5 is stamped in bottle 6 upper ends, bottle cap 5 is provided with pore and air plug 2, a transparent thin tube 4 is also inserted at bottle cap 5 middle parts, transparent thin tube 4 upper ends are set with funnel 3, insert in the liquid container 1 that is arranged in the bottle 6 transparent thin tube 4 lower ends, be loaded with band look liquid in the liquid container 1, base 7 is plastic bottle closure, and transparent thin tube 4 is transparent pen core, and funnel 3 and liquid container 1 are made for a tail-hood, material is easily got, and cost of manufacture is lower.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
