Abstract
The utility model provides a double-pendulum 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 double-pendulum experimental instrument includes a pedestal and a vertical rod fixed on the upper end of the pedestal. A cross rod s fixed on the upper end of the vertical rod. Two pendulum weights are connected below the cross rod respectively through different pendulum ropes. Each of the pendulum weights are connected through two pendulum ropes arranged in a V shape. The double-pendulum 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 double-pendulum experimental instrument is simple in structure and easy to manufacture, so that the double-pendulum experimental instrument is suitable for manufacturing manually or 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 double 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 double 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 double pendulum experiment instrument is characterized in that, comprises base and the vertical bar that is fixed on the base upper end, vertically a cross bar is fixed in the bar upper end, the cross bar below connects two pendulum weights respectively by different pendulum ropes, and each pendulum weight connects by two pendulum ropes, and two pendulum are restricted into the V-type setting.
Described vertical bar is plastic penholder, and described base is big plastic bottle closure, and described cross bar is the plastics pen core, and described pendulum weight is little bottle cap, and material is easily got, and cost of manufacture is low.
Described pendulum rope is common cotton thread or colored fine rule.
The use of experiment instrument: allow two single pendulums swing, from the movement locus of two single pendulums of top view, their track can regular being synthesized together.
The physical principle that experiment instrument relates to: single pendulum, swing synthetic.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 double 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 front view of the present utility model;
Fig. 2 is right view 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 and Figure 2,
A kind of double pendulum experiment instrument comprises base 1 and the vertical bar 2 that is fixed on base 1 upper end, and vertically a cross bar 5 is fixed in bar 2 upper ends, cross bar 5 belows connect two pendulum weights 3 respectively by different pendulum ropes 4, each pendulum weight 3 connects by two pendulum ropes 4,4 one-tenth V-type settings of two pendulum ropes, and vertically bar 2 is plastic penholder, base 1 is big plastic bottle closure, cross bar 5 is the plastics pen core, and pendulum weight 3 is little bottle cap, and material is easily got, cost of manufacture is low, and pendulum rope 4 is common cotton thread or colored fine rule.
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.
