Abstract
The utility model discloses a combined type demonstrator for a physical experiment, which comprises a substrate with a hollow cavity, and is characterized in that one end of the substrate is provided with a spring dynamometer for measuring force, the substrate is provided with a graduated scale, one side of the substrate is provided with a timing device, and one side of the substrate is further provided with an electronic scale. The combined type demonstrator for the physical experiment has a simple structure and reasonable design, can be used for conducting multi-term of physical experiments, is convenient for a teacher to use, thus improving the teaching efficiency, is convenient to carry and can effectively lightening the working intensity of the teacher.
Description
Technical field
The utility model relates to the physics teaching technical field, relates in particular to a kind of Physical Experiment combined type demonstrator.
Background technology
At present, in physics teaching, notion and laws many on the textbook all need to demonstrate by experiment and prove, so in physical teaching course, need to do many experiments, with satisfy the student understand more intuitively and grasp gained knowledge, as in mechanics teaching, the length and the weight that often need the dynamometry object, and by timer to remembering action time, in the presentation process of Hooke's law, then need to use dynamometer etc., often need obtain a physical quantity or verify some laws, need different teaching aids like this, as rule by these utensils, electronic scale, timing indicator and dynamometer etc., on the classroom, need to carry multiple apparatus like this, complex operation is wasted time and energy, and has increased teacher's working strength.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, and can carry out multinomial Physical Experiment operation, makes things convenient for teacher to use, thereby improve efficiency of teaching, is easy to carry, and can effectively alleviate the Physical Experiment combined type demonstrator of teacher's burden.
In order to reach above purpose, the technical scheme that the utility model adopted is: Physical Experiment combined type demonstrator, comprise pedestal with hollow cavity, it is characterized in that: an end of described pedestal is provided with the weight beam that is used for ergometry, described pedestal is provided with rule, one side of described pedestal is provided with timing device, and a side of described pedestal also is provided with electronic scale.
The other end of described pedestal is provided with hook.
The beneficial effects of the utility model are: simple in structure, reasonable in design, can carry out multinomial Physical Experiment operation, and make things convenient for teacher to use, thereby improve efficiency of teaching, be easy to carry, can effectively alleviate teacher's working strength.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, Physical Experiment combined type demonstrator, comprise pedestal 1 with hollow cavity, one end of described pedestal 1 is provided with the weight beam 2 that is used for ergometry, described pedestal 1 is provided with rule 3, one side of described pedestal 1 is provided with timing device 4, and a side of described pedestal 1 also is provided with electronic scale 5.When teacher demonstrates Hooke's law, only can demonstrate spring when being elongated to the student by weight beam 2 by this structure, the length of its elongation is directly proportional with external force, can allow the student intuitively understand, and has improved efficiency of teaching; And need carry out mechanics when demonstration, object can be placed on the pedestal 1, can measure the length of this object by rule 3, and it is carried out gravimetry by observing electronic scale 5, and determine the times by timing device 4 again, can determine calculative many group Physical Experiment Data by length, gravity, time like this, easy to use, time saving and energy saving, can carry out multinomial Physical Experiment operation, alleviated teacher's work load.
Can carry out linear measure longimetry to object by the scale on the rule 3, easy to use.
Described electronic scale 5 is convenient to measure gravity.
The other end of described pedestal 1 is provided with hook 6.Be convenient to teacher and be suspended on the blackboard and impart knowledge to students by linking up with 6.
The utility model is simple in structure, and is reasonable in design, can carry out multinomial Physical Experiment operation simultaneously, makes things convenient for teacher to use, thereby improves efficiency of teaching, is easy to carry, and can effectively alleviate teacher's working strength.
