Abstract
The utility model provides an elasticity demonstrator for physical teaching, and solves the shortcoming in the prior art that no visual display apparatuses can be utilized to demonstrate the relationship between the elasticity and the deformation of a spring during the physical teaching, so that a teacher only carries out abstract explanation, students are difficult in acceptance, and the teaching effect is poor. The elasticity demonstrator comprises a support, an emitting plate, an emitting basket and a spring. The support is connected with and supports the emitting plate via a hinge. The two ends of the spring are respectively connected with an emitting plate and the support. The emitting basket is disposed at one end of the emitting plate. The elasticity demonstrator has the advantages of simple structure and visual and clear display, and is an ideal physical teaching apparatus.
Description
Affiliated technical field
The utility model relates to a kind of physics teaching instrument, particularly a kind of physics teaching elastic force and deformation displacement demonstrator.
Background technology
In the prior art, elastic force during physics teaching, promptly the relation demonstration of the elastic force of spring and distortion does not also have display instrument directly perceived, and teacher is abstract explanation, and the student accepts difficulty, and teaching efficiency is poor.
Summary of the invention
For overcoming in the prior art, the relation demonstration of the elastic force of spring and distortion does not also have display instrument directly perceived during physics teaching, teacher is abstract explanation, the student accepts difficulty, the deficiency of teaching efficiency difference, the utility model designs a kind of physics teaching elastic force demonstrator, and this demonstrator can show intuitively that the elastic force size is relevant with camber of spring.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of physics teaching elastic force demonstrator, this elastic force demonstrator comprises: support, expelling plate, emission basket and spring, support is connected support through hinge with expelling plate, spring one end is connected with expelling plate, the other end is connected with support, and the emission basket is arranged on the end of expelling plate.
The beneficial effect that the utility model is realized is that simple in structure, demonstration is clear directly perceived, is a kind of desirable physics educational apparatus.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Accompanying drawing is the utility model synoptic diagram.
In the accompanying drawing, 1 support, 2 expelling plates, 3 emission baskets, 4 springs, 5 demonstration balls.
Embodiment
Referring to accompanying drawing, a kind of physics teaching elastic force demonstrator, this elastic force demonstrator comprises: support 1, expelling plate 2, emission basket 3 and spring 4, support 1 is connected support through hinge with expelling plate 2, spring 4 one ends are connected with expelling plate 2, the other end is connected with support 1, and emission basket 3 is arranged on the end of expelling plate 2.During use, to demonstrate ball 5 and be placed in the emission basket 3, depress an end of expelling plate 2, expelling plate 2 is rotated around support 1 upper hinge, spring 4 is stretched, after spring 4 is stretched to certain-length, unclamp expelling plate 2, spring 4 spring returns, expelling plate 2 rotates the demonstration ball 5 that will launch in the basket 3 around support 1 and launches, repeat repeatedly to launch, measure the distance of demonstration ball 5 emissions and the relation of spring 4 tensile elongations, reach the purpose of teaching.
