Utility model content
The purpose of this utility model is to provide a kind of Archimedes principle demonstrator, and it uses integral structure, it is possible to carry out lecture experiment when waiting efficiently, experimental phenomena is obvious, simple operation, can carry out multiple research, is presented by lively objective blunt experimental apparatus by abstract theoretical knowledge.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Archimedes principle demonstrator, including base, base is respectively provided on two sides with the first fixed support and the second fixed support, and the first fixed support connects connecting rod by knob, and connecting rod end connects the first ergometer by flexible piece, first ergometer bottom is spilling water cup, spilling water cup top connects pipeline by through hole, and spilling water cup is located on fixing seat, and fixing seat is located on base, second fixed support connects the second ergometer by flexible piece, and the second ergometer bottom connects container.
As the further improvement of above-mentioned technology, described base uses Steel material to make.
As the further improvement of above-mentioned technology, described flexible piece selects cord structure.
As the further improvement of above-mentioned technology, described selection for pipeline adapter tube.
As the further improvement of above-mentioned technology, bucket selected by described container.
Compared with prior art, the beneficial effects of the utility model are: can regulate connecting rod position on the first fixed support by knob, and then the height of regulation connecting rod, first ergometer and the second ergometer are for measuring the size of power, first ergometer bottom is spilling water cup, spilling water cup is built with water, for weight is floated, by comparing liquid gravity size in buoyancy size suffered by weight and bucket, i.e. can verify that " Archimedes principle ", integral structure is used to carry out lecture experiment efficiently when can wait, experimental phenomena is obvious, simple operation, multiple research can be carried out, abstract theoretical knowledge is presented by lively objective blunt experimental apparatus, student is made to become apparent from understanding to the understanding of Archimedes principle, can be good at improving presenting property of physics teaching.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
nullA kind of Archimedes principle demonstrator，Including base 1，Base 1 uses Steel material to make，Base 1 is respectively provided on two sides with the first fixed support 2 and the second fixed support 3，Connecting rod 5 is connected by knob 4 on first fixed support 2，Connecting rod 5 height can be adjusted，Connecting rod 5 end connects the first ergometer 6 by flexible piece，Flexible piece selects cord structure，First ergometer 6 bottom is spilling water cup 7，Spilling water cup 7 is built with a certain amount of liquid，Spilling water cup 7 top connects pipeline by through hole，Selection for pipeline adapter tube 8，Spilling water cup 7 is located on fixing seat 11，Fixing seat 11 is located on base 1，Second fixed support 3 connects the second ergometer 9 by flexible piece，Second ergometer 9 bottom connects container 10，First ergometer 6 and the second ergometer 9 are for measuring the size of power，Bucket selected by container 10，Bucket is for being collected the water flowed out from adapter tube 8.
nullDuring utility model works，Connecting rod 5 is connected by knob 4 on first fixed support 2，Knob 4 is adjustable knob，The connecting rod 5 position on the first fixed support 2 can be regulated by knob 4，And then the height of regulation connecting rod 5，Connecting rod 5 end and the second fixed support 3 end are respectively equipped with the first ergometer 6 and the second ergometer 9，First ergometer 6 and the second ergometer 9 are for measuring the size of power，First ergometer 6 bottom is spilling water cup 7，Spilling water cup 7 is built with water，For weight is floated，When testing，First ergometer 6 and the second ergometer 9 are hung on connecting rod 5 and the second fixed support 3 respectively，Weight is bundled in the first ergometer 6 bottom by cord，The gravity of weight is measured in atmosphere by the first ergometer 6，Bucket is bundled in the second ergometer 9 bottom by cord，The gravity of bucket is measured in atmosphere by the second ergometer 9，Turning knob 4，Connecting rod 5 moves downward，Drive weight moves downward，During then weight is gradually immersed into the liquid of spilling water cup 7，Adapter tube 8 is connected by through hole on the upside of spilling water cup 7，Adapter tube 8 bottom is bucket，When weight is gradually immersed into certain volume，Stop the rotation knob 4，The liquid risen is entered in bucket by adapter tube 8，Read the first ergometer 6 and the second ergometer 9 registration above simultaneously，Continue turn knobs 4，Weight is allowed to immerse further in spilling water cup 7 liquid，Again read off the first ergometer 6 and reading of the second ergometer 9，By comparing liquid gravity size in buoyancy size suffered by weight and bucket，I.e. can verify that " Archimedes principle "，This utility model uses integral structure to carry out lecture experiment efficiently when can wait，Experimental phenomena is obvious，Simple operation，Multiple research can be carried out，Abstract theoretical knowledge is presented by lively objective blunt experimental apparatus，Student is made to become apparent from understanding to the understanding of Archimedes principle，Can be good at improving presenting property of physics teaching.
The foregoing is only this utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain are limited; to those skilled in the art; the scheme obtained by the equivalent and obvious change that all utilization this utility model description and diagramatic content make should be can appreciate that, all should be included in protection domain of the present utility model.
