Abstract
The utility model provides a buoyancy teaching instrument in physics. Two sides of a base plate are symmetrically provided with vertical rods in a structure of the buoyancy teaching instrument in physics; movable sleeve rings are symmetrically sleeved on the two vertical rods, provided with locking knobs and connected with water storage bottles through a fixed rod, a bottle cover of the water storage bottle corresponds to an opening at an upper end of a water storage tank, an upper portion of the water storage tank is provided with a floating ball, and the floating ball is connected with a dynamometer through connection wire. Compared with the prior art, the buoyancy teaching instrument in physics has advantages of reasonable design, simple structure, easy processing, operational convenience, visual demonstration, and the like, can directly demonstrate reasons and a process of buoyancy generation to students, can effectively measure buoyancy magnitude according to water amount in the water storage tank and helps the students to understand and memorize content in the chapter.
Description
1, technical field
The utility model relates to a kind of physical teaching aid, specifically a kind of physics buoyancy teaching appliance.
2, background technology
Buoyancy phenomenon is the key content of Physics Course, is immersed in the effect that object in the liquid can be subject to gravity and buoyancy, and when buoyancy during greater than gravity, object can float on the liquid level.There is not now corresponding educational aid to use, the teacher also only can be by the oral account explanation, and process and reason that buoyancy produces all can't show the student intuitively, and the large pupil of buoyancy also can't know, do not have corresponding teaching aid intuitively to be shown to the student, be unfavorable for student's understanding, memory.
3, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of physics buoyancy teaching appliance is provided.
The technical solution of the utility model realizes in the following manner, the symmetria bilateralis of base plate is provided with vertical rod in its structure, symmetry is socketed with slip collar in two vertical rods, be provided with tightening knob on the slip collar, slip collar is connected with water storage bottle by fixed bar, the opening of the water storage box upper end that arranges on the bottle cap that arranges on the water storage bottle and the base plate is corresponding, and the top of water storage box is provided with ball float, and ball float is connected by connecting line with the dynamometer of water storage box bottom setting.
Be provided with scale on the above-mentioned water storage box.
Above-mentioned dynamometer is set to electronic dynamometer.
Above-mentioned dynamometer is set to weight beam.
The utility model has the advantages that:
A kind of physics of the present utility model is compared with existing technology with the buoyancy teaching appliance, have reasonable in design, simple in structure, be easy to the characteristics such as processing, easy to use, demonstrating visual, reason and the process that buoyancy produces directly can be showed the student, can according to how many situations of water in the water storage box, effectively measure the size cases of buoyancy, help the student to understand, remember this chapter content.
4, description of drawings
Fig. 1 is the structural representation that a kind of physics is used the buoyancy teaching appliance;
Mark in the accompanying drawing represents respectively;
1, slip collar; 2, fixed bar; 3, water storage bottle; 4, bottle cap; 5, tightening knob; 6, vertical rod; 7, dynamometer; 8, connecting line; 9, base plate; 10, ball float; 11, water storage box.
5, embodiment
Below in conjunction with accompanying drawing a kind of physics of the present utility model is described in detail below with the buoyancy teaching appliance.
As shown in Figure 1, a kind of physics of the present utility model is provided with vertical rod 6 with the symmetria bilateralis of base plate 9 in its structure of buoyancy teaching appliance, symmetry is socketed with slip collar 1 in two vertical rods 6, be provided with tightening knob 5 on the slip collar 1, slip collar 1 is connected with water storage bottle 3 by fixed bar 2, the opening of water storage box 11 upper ends of setting is corresponding on the bottle cap 4 that arranges on the water storage bottle 3 and the base plate 9, the top of water storage box 11 is provided with ball float 10, and ball float 10 is connected by connecting line 8 with the dynamometer 7 that water storage box 11 bottoms arrange.
Be provided with scale on the water storage box 11, can read easily the volume of water storage box 11 interior water.
A kind of physics of the present utility model is very simple and convenient with its processing and fabricating of buoyancy teaching appliance, can process shown in the accompanying drawing to specifications.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
