Abstract
The utility model relates to a plane mirror imaging demonstration instrument for teaching, comprising an experimental platform and an iron sheet coated on the outside of the experimental platform. The experimental platform is provided with a graduation line. A card slot supplied for glass to plug is fixed in the middle of two sides of the experimental platform. The candle lamp with wick comprises a columnar glass tube body and a flamboyancy lamp cap. A plurality of LEDs are arranged in the flamboyancy lamp cap. A quartz oscillator chip, a button battery, a button switch and a magnet are arranged in the columnar glass tube body. The magnet is arranged on the bottom of the columnar glass tube body and is adsorbed with the iron sheet of the experimental platform. After a plurality of LEDs is in parallel connection, one end of a plurality of LEDs is electrically connected with cathode of the button battery via the button switch, and the other end is electrically connected with the cathode of the button battery via the quartz oscillator chip. The button switch is arranged on the columnar glass tube body. The utility model cannot pollute environment and be in favor of physical and mental health of students.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly relates to a kind of teaching mirror imaging demonstrator.
Background technology
The student generally makes light source with candle when probing into the object point of mirror imaging, can drop down wax oil when mobile candle, the time regular meeting flow on hand; produce a large amount of carbon dioxides simultaneously; polluted indoor air, the student does experiment in smoke fire burns, and is unfavorable for student's physical and mental health.Accelerate if open the window indoor air flows, the swing of candle flame is violent, the imaging instability.After the several classes of experiments, be wax oil everywhere on the experiment table.
Summary of the invention
The purpose of this utility model is for overcoming the defective that above-mentioned prior art exists, and a kind of teaching level crossing demonstrator is provided, and this demonstrator can not drop down wax oil, can not produce great amount of carbon dioxide gas yet.
The technical scheme that adopts is:
A kind of teaching mirror imaging demonstrator, comprise experiment porch, the external packets of experiment porch is covered with iron sheet, scale mark is arranged on the experiment porch, two middle side parts on the experiment porch are fixed with the draw-in groove for the glass plug, two side angles of glass plate lower end insert in the draw-in groove, there are wick candle lamp and no wick candle lamp to be divided into the both sides of glass plate, described have a core candle lamp, comprise a column canals of stilling and a flamboyancy lamp holder, be provided with a plurality of light emitting diodes in the flamboyancy lamp holder, be provided with a quartz crystal oscillator chip in the column canals of stilling, one twist button battery, one push switch and a magnet, adsorb mutually with the iron sheet of experiment porch the bottom that described magnet is arranged on the column canals of stilling, and after a plurality of light emitting diode parallel connections, the one end connects with the negative electricity of twist button battery through switch, the other end is connected with the negative electricity of twist button battery through the quartz crystal oscillator chip, and described pushbutton switch is installed on the column body.
The candle lamp that the utility model is used, the ceraceous candle is in burning, and flame does not rock; Imaging is clear, is not subjected to airflow influence, because magnet is adsorbed on the iron sheet of platform, the student that the platform tiltable helps all angles during experiment observes, and tests free from environmental pollutionly, helps student's physical and mental health.
