Abstract
The utility model provides a rolling pendulum experimental instrument, relates to the field of scientific experimental apparatuses and teaching and is to solve problems that corresponding experimental fittings are short at present and functions of the conventional experimental fittings are single. The experimental instrument comprises a base and two vertical rods fixed on upper ends of the base. Upper ends of the two vertical rods are fixedly connected by a transverse rod. The experimental instrument also comprises a steel wheel. Central rods are fixed on two sides of the steel wheel. Two soft ropes connect between the central rods and the transverse rod. The rolling pendulum experimental instrument provided by the utility model is made of easily-obtained articles such as plastic penholders and plastic bottle covers as materials. The experimental instrument is simple in a structure and easy to manufacture, so that the experimental instrument is suitable for student manual manufacturing and manufacturing at home.
Description
Technical field:
The utility model relates to scientific experiment device and teaching field, is specifically related to a kind of rolling pendulum 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 rolling pendulum 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 rolling pendulum experiment instrument is characterized in that, comprises base and two vertical bars that are fixed on the base upper end, two vertical bar upper ends are fixedly connected by a cross bar, also comprise a steel wheel, fixedly there is center-pole the steel wheel both sides, are connected by two tightropes between described center-pole and the cross bar.
Described tightrope is obliquely installed, and what tightrope was can be successively smooth is wrapped on the center-pole, and tightrope is colored.
Described vertical bar is lifting regulating rod, can regulate the height that steel wheel moves up and down.
Described vertical bar is plastic penholder, and described base is plastic bottle closure, and described cross bar is the plastics pen core, and material is easily got.
The use of experiment instrument: steel wheel is scrolled up, be rolled into topmost, the both sides tightrope on center-pole, unclamps hand and freely rolls down by steel wheel equably, and at this moment steel wheel will roll up and down freely back and forth.
The physical principle that experiment instrument relates to: mechanical energy is changed mutually.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:
The rolling pendulum 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 rolling pendulum experiment instrument comprises that base 6 and 3, two vertical bars of two vertical bars, 3 upper ends that are fixed on base 6 upper ends are fixedly connected by a cross bar 1, also comprise a steel wheel 5, fixedly there is center-pole 4 steel wheel 5 both sides, are connected by two tightropes 2 between center-pole 4 and the cross bar 1, and tightrope 2 is obliquely installed, what tightrope 2 was can be successively smooth is wrapped on the center-pole 4, tightrope is colored, and vertically bar 3 is plastic penholder, and base 6 is plastic bottle closure, cross bar 1 is the plastics pen core, and material is easily got.
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.
