Description
Technical field
The utility model relates to a kind of experimental provision for verifying parallelogram rule, belongs to education experiment field.
Background technology
In the Physical Experiment of checking parallelogram law, traditional experiment method utilizes spring balance and bungee, the power measured on each edge direction by the parallelogram independently built is verified, this method is more difficult operation not only, and error is larger, disturb by factors such as spring balance precision, bungee quality, be difficult to obtain experimental data accurately, affect the laboratory study of student.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, compact conformation, the experimental provision for verifying parallelogram rule of functional module energy organic assembling.
The technical scheme in the invention for solving the above technical problem is: a kind of for verifying that the experimental provision of parallelogram rule comprises experiment plate and message handler, the upper surface of experiment plate is provided with stress and strain model line, the intersection point of stress and strain model line is all provided with elastic sensor, elastic sensor is all electrically connected with message handler, and message handler is provided with display screen.
As preferably, experiment plate is square shape.
As preferably, stress and strain model line is square net, and square net has 36, and square net is distributed in the upper surface of experiment plate by the mode of 6 × 6, certainly, experimentally needs, and stress and strain model line also can be other shape, quantity and distribution mode.
As preferably, elastic sensor is provided with dynamometer link, and dynamometer link is provided with draw-in groove, and draw-in groove is semicircle draw-in groove.
As preferably, the utility model also comprises printer, and printer is electrically connected with message handler, is convenient to student and prints experiment drawing and data, complete laboratory report.
As preferably, display screen is LCDs, is convenient to more clearly show experimental data, can be the display screen of the other types such as LED display certainly.
As preferably, the bottom surface of experiment plate is provided with rubber mat, is convenient to put, and avoids scratching desktop.
The utility model compared with prior art, have the following advantages and effect: the utility model compact conformation, novelty, utilize elastic sensor to respond to the direction of the size of elastic force, accuracy is higher, but equally distributed stress and strain model line student arranges wiring freely, metering system variation, data are more accurate, can obtain higher Experiment Result.

Label declaration: 1-experiment plate, 2-message handler, 3-stress and strain model line, 4-display screen, 5-dynamometer link, 6-draw-in groove, 7-printer, 8-rubber mat.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As depicted in figs. 1 and 2, the present embodiment for verifying that the experimental provision of parallelogram rule comprises experiment plate 1 and message handler 2, the upper surface of experiment plate 1 is provided with stress and strain model line 3, the intersection point of stress and strain model line 3 is all provided with elastic sensor, elastic sensor is all electrically connected with message handler 2, and message handler 2 is provided with display screen 4.
Experiment plate 1 is square shape.
Stress and strain model line 3 is square net, and square net has 36, and square net is distributed in the upper surface of experiment plate by the mode of 6 × 6, certainly, experimentally needs, and stress and strain model line 3 also can be other shape, quantity and distribution mode.
Elastic sensor is provided with dynamometer link 5, and dynamometer link 5 is provided with draw-in groove 6, and draw-in groove 6 is semicircle draw-in groove.
The present embodiment also comprises printer 7, and printer 7 is electrically connected with message handler 2, is convenient to student and prints experiment drawing and data, complete laboratory report.
Display screen 4 is LCDs, is convenient to more clearly show experimental data, can be the display screen of the other types such as LED display certainly.
The bottom surface of experiment plate 1 is provided with rubber mat 8, is convenient to put, and avoids scratching desktop.
Adopt said structure, during experiment, first opening elastic sensor and message handler 2, then by the shape of parallelogram, bungee is distributed on experiment plate 1, bungee is fixed by the draw-in groove 6 on dynamometer link 5, message handler 2 obtains the information of stressed elastic sensor and the direction of power and size is shown by display screen 4 simultaneously, student directly can understand the size and Orientation of power by display screen 4, by changing the distribution of bungee, just can verify the parallelogram law of power.
Above content described in this instructions is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model instructions or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
