Description
Technical field:
The utility model belongs to technical field of teaching instruments, is a kind of teaching demonstration instrument that utilizes tongue tube.
Background technology:
At present, mainly be that teacher explains according to book contents in the physics teaching, seldom utilize instruments used for education to demonstrate, the student understands difficulty, and electronic devices and components especially are if adopt suitable instruments used for education limit demonstration, the limit explanation can reach the effect of getting twice the result with half the effort.
Summary of the invention:
The purpose of this utility model is that a kind of instruments used for education that mainly utilize tongue tube to make for components and parts will be provided, thereby be convenient to the student performance and the effect of tongue tube is got information about.
Tongue tube is made up of the metal electrode of two magnetic materials in the glass, when not being subjected to magnetic action, two metal electrodes separate, do not contact mutually, when being subjected to magnetic action, contact with each other, after magnetic action is removed, be separated from each other again, visible tongue tube is a magnetic switch that can play mechanical effect under magnetic action.
The scheme of the utility model technical solution problem is to adopt tongue tube, permanent magnet pivoted frame, light emitting diode and power switch to constitute the tongue tube multi-function device, wherein tongue tube, light emitting diode and power switch constitute series circuit, the positive and negative of battery supply is connected with the series circuit two ends respectively, the permanent magnet pivoted frame is made of portal, rotating shaft and bar permanent magnet, middle waist at portal is equipped with rotating shaft, the middle part of permanent magnet is fixed in the rotating shaft, permanent magnet two ends position is with metal cap respectively, and the permanent magnet pivoted frame is near tongue tube.Metal cap is the magnetic metal material.Portal and rotating shaft are nonmagnetic substance.
This device has following function:
1, observe and change the flash of light speed of light emitting diode: remove the magnet resistant cap of permanent magnet one termination, the energized switch, the rotating shaft of permanent magnet pivoted frame is moved in fast or slow-speed, can observe the flash state of light emitting diode; Remove the magnet resistant cap of permanent magnet two ends, the energized switch, the rotating shaft of permanent magnet pivoted frame is moved in fast or slow-speed, can observe the flash state of light emitting diode.
2, detect magnetic material and nonmagnetic substance: the magnet resistant cap of removing permanent magnet one or two ends, the energized switch, sheet metal to be measured is inserted in the rotating shaft of rotation permanent magnet pivoted frame between permanent magnet and tongue tube, if the light of light emitting diode extinguishes, it is magnetic material that sheet metal is inserted in expression; If the luminance of light emitting diode is constant, it is nonmagnetic substance that sheet metal is inserted in expression.
3, the Distribution of Magnetic Field of observation difformity permanent magnet: under the state of energized switch, with annular and plate shape permanent magnet is example, with the close tongue tube of permanent magnet, and the position of movable permanent magnet body all around, observe the luminance of light emitting diode, the Distribution of Magnetic Field that can observe plate shape is more intensive than the Distribution of Magnetic Field of annular, scope big, act on tangible result, the basis that Here it is plate shape, particularly garden shape permanent magnet is widely adopted.
The auxilliary light emitting diode of another kind of color in parallel is equipped with single-pole double-throw switch (SPDT) between light emitting diode and the power switch on light emitting diode, like this, the conversion single-pole double-throw switch (SPDT), when teaching demonstration is operated, flash of light color difference.
Two ends at tongue tube connect electronic calculator, and the equals' key circuit of electronic calculator is connected the two ends of tongue tube.Can utilize the accumulation function of electronic calculator, this device and electronic calculator are formed counter, only 1 and 2 accumulation function is described below.
A, accumulation function to 1, its running program is:
A, 0 button add 1 button and equal to be shown as 1, are shown as 0 by 0 key, existing begin counting more than 5 times by equals' key and are: 1,2,3,4,5 or the like.From the beginning re-use once counting as needs, be shown as 0, begin counting again by equals' key equally by 0 key.
B, 1 button add 1 button and equal to be shown as 2, are shown as 0 by 0 key, press equals' key equally, obtain 1 accumulated counts equally.
B, accumulation function to 2, its running program is:
A, 0 button add 2 buttons and equal to be shown as 2, are shown as 0 by 0 key, and existing to begin counting by equals' key be 2,4,6,8 or the like.
Equally, cannot do the accumulation function counting of other number, no longer introduce.
C, counter use-case
Disconnecting power switch selects one and two permanent magnets, observes respectively.
Adopt several 1 accumulation function, in 5 week and 10 weeks of rotating shaft, observe the electronic calculator screen display, i.e. the connection number of times of tongue tube.
The utlity model has rich knowledge and interest, structure is directly perceived, and cost is low, easy and simple to handle, to cultivating manipulative ability very vital role is arranged, as a kind of instruments used for education, mainly to as if students in middle and primary schools, so development prospect is huge, to carrying out and promote science popularization to enter family very great scope of land is arranged.
