Description

A kind of mathematical education clinometer
Technical field
This utility model relates to teaching aid field, particularly relates to a kind of mathematical education clinometer.
Background technology
In mathematical education, for the understanding that angle is relevant, it usually needs teacher uses set square and chalk on blackboard Manually drawing relevant figure, not only efficiency is low, takies instructional blocks of time, and the measurement for the elevation angle, the angle of depression etc. is only limitted to written more Seeing that figure recognizes, student is difficult to principle and the method that intuitivism apprehension is measured, and imparts knowledge to students dry as dust, and student understands more difficulty, for this We design a kind of mathematical education clinometer, are used for solving the problems referred to above.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of mathematical education proposed is used Clinometer.
To achieve these goals, this utility model adopts the technical scheme that
A kind of mathematical education clinometer, including index dial, the edge of described index dial is provided with graduation mark, described indexing Dish is provided with diaphragm plate and midfeather, and described diaphragm plate and midfeather are mutually perpendicular to be divided into index dial four parts, described horizontal stroke The junction of dividing plate and midfeather is provided with boss, and described boss connects has rotating shaft, described rotating shaft to be provided with straight angle plate and right angle Plate, described straight angle plate and L-square be mutually perpendicular to, and the back side of described index dial is provided with erecting device.
Preferably, described index dial uses wooden one side blank material to make.
Preferably, described diaphragm plate, midfeather, straight angle plate and L-square use organic plastic material to make, and surface is divided It is not provided with different coloured coatings.
Preferably, use between described boss and rotating shaft and threaded.
Preferably, described erecting device uses Magnet or hook or sucker structure.
In this utility model, use index dial and the structure of movable pointer, can arbitrarily set arbitrarily angled, meet angle The teaching of the knowledge such as classification, complementary angle, supplementary angle, it is to avoid the time waste that manual picture causes, index dial uses whiteboard structure, joins Close white board marker and whiteboard eraser, writing and wiping of angle label can be realized, dividing plate use different colours as the sideline of angle, It is easier Division identification, geometrical principle can be utilized simultaneously to measure the elevation angle or the angle of depression, make student intuitively come to realize the principle of angle measurement, Simplify teaching, change and quiet be, the interest of enhancing knowledge, motivate students' interest in learning, be greatly improved the teaching efficiency in classroom, Rational in infrastructure, easy to use.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is forward sight structural representation of the present utility model;
Fig. 3 is backsight structural representation of the present utility model.
In figure: 1 index dial, 2 graduation marks, 3 diaphragm plates, 4 midfeathers, 5 boss, 6 rotating shafts, 7 straight angle plates, 8 L-squares, 9 peaces Assembling device.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.
With reference to Fig. 1-3, a kind of mathematical education clinometer, including index dial 1, index dial 1 uses wooden one side blank material Material is made, and white board marker and whiteboard eraser can be used to write and wipe, and the edge of index dial 1 is provided with graduation mark 2, index dial 1 It is provided with diaphragm plate 3 and midfeather 4, diaphragm plate 3 and midfeather 4 and is mutually perpendicular to be divided into index dial 1 four parts, diaphragm plate 3 Two ends corresponding with " 0 " scale and " 180 " scale respectively, the junction of diaphragm plate 3 and midfeather 4 is provided with boss 5, boss 5 Upper connection has rotating shaft 6, uses and threaded between boss 5 with rotating shaft 6, can be set by the relative angle of regulation rotating shaft 6 with boss 5 Fixed required angle, rotating shaft 6 is provided with straight angle plate 7 and L-square 8, straight angle plate 7 and L-square 8 and is mutually perpendicular to, diaphragm plate 3, vertical Dividing plate 4, straight angle plate 7 and L-square 8 use organic plastic material to make, and surface is respectively equipped with different coloured coatings, as The sideline of angle, it is simple to Division identification, the back side of index dial 1 is provided with erecting device 9, erecting device 9 use Magnet or hook or Sucker structure, it is simple to index dial 1 fixing on blackboard.
Operation principle: index dial 1 in use, is fixed on blackboard by fixing device 9, and makes horizontal stroke by this utility model Dividing plate 3 is horizontal, and by rotating shaft 6, makes straight angle plate 7 point to certain graduation position, can realize predetermined angle Set, use white board marker angular dimension label, the teaching of the relevant knowledges such as the classification of angle, complementary angle, supplementary angle can be met, when being used as When clinometer uses, first regulation rotating shaft 6 makes the two ends of straight angle plate 7 be respectively directed to " 0 " scale and " 180 " scale, stirs L-square 8 Pointing to target location, read the scale corresponding to straight angle plate 7 from index dial 1, the geometry utilizing " complementary angle of isogonism is equal " is former Reason, measures the angle of depression or the elevation angle of target location.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality Novel technical scheme and utility model thereof conceive equivalent or change in addition, all should contain at protection model of the present utility model Within enclosing.
