Abstract
The utility model relates to the field of teaching and demonstration, particularly relates to a Brownian movement physical phenomenon teaching demonstrator, which comprises a laser light source, a concave lens, a beaker, a laser light source bracket, a concave lens bracket, a beaker bracket and a base. The Brownian movement physical phenomenon teaching demonstrator is characterized in that the laser light source is fixed to one end of the laser light source bracket, the beaker is fixed to one end of the beaker bracket, the other end of each of the laser light source bracket and the beaker bracket is fixed on the base, the central points of the laser light source and the beaker are positioned on the same horizontal line, the other end of the concave lens bracket is movably connected with the base, the other end is fixedly connected with the concave lens, and the concave lens is arranged between the laser light source and the beaker. The Brownian movement physical phenomenon teaching demonstrator has the advantages of simple structure, ingenious design and obvious demonstration effect, and can satisfy the purpose of being used for observation by many people at the same time.
Description
Technical field
The utility model relates to teaching demonstration field, is specifically related to Brownian movement physical phenomenon education demonstrator.
Technical background
In senior middle school physics teaching, when teacher observes the Brownian motion experiments of carbon granules in ink, adopt the accessories such as approximately 600 power microscopes, test tube, microslide, cover glass, suction pipe, burnt black ink, operation more complicated, and limitation is larger, only allow a people to observe, can not allow all students personally observe Brownian movement phenomenon simultaneously.
Summary of the invention
In order to address the above problem, the utility model provide a kind of simple in structure, design ingenious, demonstration successful, can meet the Brownian movement physical phenomenon education demonstrator that many people observe simultaneously.
The utility model Brownian movement physical phenomenon education demonstrator, comprises LASER Light Source, concavees lens, beaker, LASER Light Source support, concavees lens support, beaker support, base; A LASER Light Source is fixed in the one end that it is characterized in that described LASER Light Source support, a beaker is fixed in one end of beaker support, the other end of described LASER Light Source support and beaker support is all fixed on base, the central point of described LASER Light Source and beaker is positioned on same level line, one end of described concavees lens support is flexibly connected with base, the other end is fixedly connected with concavees lens, and described concavees lens are between LASER Light Source and beaker.
Preferably, base is long 25cm, wide 15cm, the compacting plank of thick 2cm.
Preferably, concavees lens are that diameter is the concavees lens of 8cm.
Preferably, Brownian movement physical phenomenon education demonstrator also comprises screen, and screen central point and LASER Light Source central point, beaker central point are positioned on same level line.
The utility model structure is simple, it is ingenious to design, demonstration successful, can meet many people and observe simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of Brownian movement physical phenomenon education demonstrator.
Reference numeral: 1-LASER Light Source, 2-base, 3-LASER Light Source support, 4-concavees lens support, 5-concavees lens, 6-beaker support, 7-beaker, 8-screen.
Embodiment
The utility model is simple in structure, the life that can have drawn from, and the utility model Brownian movement physical phenomenon education demonstrator comprises LASER Light Source 1, concavees lens 5, beaker 7, LASER Light Source support 3, concavees lens support 4, beaker support 6, base 2, a LASER Light Source 1 is fixed in one end of LASER Light Source support 3, a beaker 7 is fixed in one end of beaker support 6, the other end of LASER Light Source support 3 and beaker support 6 is all fixed on base 2, the central point of LASER Light Source 1 and beaker 7 is positioned on same level line, one end of concavees lens support 4 is flexibly connected with base 2, the other end is fixedly connected with concavees lens 5, concavees lens 5 are between LASER Light Source 1 and beaker 7, regulate concavees lens support 4, can make concavees lens central point fluctuate at LASER Light Source 1 and beaker 7 central point place horizontal lines, and then make the laser that LASER Light Source 1 is launched to be irradiated to beaker 7 through concavees lens 5, obtain Brownian movement physical phenomenon.Select long 25cm, wide 15cm, the compacting plank of thick 2cm does base 2, it is the concavees lens of 8cm that LASER Light Source 1 selects laser pen, concavees lens 5 to select diameter, beaker 7 adopts waste and old 220V, the incandescent light bulb of 40W, and LASER Light Source support 3, concavees lens support 4 adopt crude iron silk fixed laser pen and concavees lens 5; Incandescent lamps is removed with place's ebonite, and at screw, place penetrates iron wire, and a composition door type frame is fixed on base 2, and with incandescent light bulb splendid attire starch suspension.In making, make the light of laser pen transmitting be radiated at incandescent lamp with crooked position through concavees lens 5, on the metope of the screen 8 of ray cast outside one meter or white, can obtain the Brownian movement physical phenomenon of successful.
