Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of for mathematical education mapping blackboard.
Background technology
Mathematics, abbreviation is the ancient subject of of the concept such as research quantity, structure, change, space and information, the one of formal science is belonged to viewed from certain angle. be divided into higher mathematics and elementary mathematics, the also set of handlebar senior middle school complexity, algebraically, geometry are called medium mathematics.It plays irreplaceable effect in development of human history and social life, is also study and the requisite basic tool of research modern science and technology.
In the teaching process of mathematics, usually having a few part to need to adopt drawing tool to be mapped by teacher on blackboard is student explain again, student is made to follow the mathematical knowledge of comprehensively understanding figure and study geometric correlation with this, in traditional mathematical education process, run into the mathematical knowledge of professor's Students ' Learning geometric correlation, just see the ruler that teacher needs to carry a variety of mapping and will use before entering classroom, the consumption of muscle power is added to the teacher attended class, its mathematics teacher or while ruler is placed on a blackboard panel hand and fixes in mapping process at school, while map with another hand, but its ruler easily skids at blackboard panel, ruler is pressed at blackboard panel by an one hand, always skid at picture ruler in general and cause the interruption of mapping process, have impact on drawing efficrence, also efficiency of attending class has been delayed, waste the class period, use inconvenience.
Summary of the invention
For the problems referred to above, the utility model provides a kind of for mathematical education mapping blackboard, solves during teacher's mathematics is given lessons and drawing tool cannot be made to fix at blackboard drawing and cause drawing efficrence to reduce, affect the problem of teaching quality.
For achieving the above object, the technical solution of the utility model is specific as follows:
A kind of for mathematical education mapping blackboard, comprise blackboard 1, support 2; It is characterized in that: described support 2, its top is fixedly installed blackboard 1, and bottom is equipped with pulley 3; The plate face of described blackboard 1 evenly arranges slide rail 11, hinged with one end of straight plate 5, set square 7, ruler 8 respectively by wing bolt 4 on described slide rail 11, the other end of wherein said straight plate 5 arranges through hole 6, and the other end of described ruler 8 is hinged with one end of short chi 10 by knob 9.
Wherein a kind of for mathematical education mapping blackboard, described straight plate 5, set square 7, ruler 8 and short chi 10, its material is specially plastics.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, easy to operate, easy to use, simple operation, solve during teacher's mathematics is given lessons and drawing tool cannot be made to fix at blackboard drawing and cause drawing efficrence to reduce, affect the problem of teaching quality, facilitate in teaching mathematical education process and map on blackboard, avoid mathematics teacher and carry the problem that many drawing tools increase labour intensity, the setting of through hole 6, penholder is conducive to enter to draw, the setting of slide rail 11, be conducive to straight plate 5, set square 7, ruler 8 carries out the movement of upper-lower position, the setting of wing bolt 4, be conducive to fixing straight plate 5, set square 7, the position of ruler 8 on slide rail 11, practical reliable, improve drawing efficrence, save the class period.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1. blackboard, 2. support, 3. pulley, 4. wing bolt, 5. straight plate, 6. through hole, 7. set square, 8. ruler, 9. knob, 10. short chi, 11. slide rails.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the utility model is further described:
A kind of for mathematical education mapping blackboard, comprise blackboard 1, support 2; It is characterized in that: described support 2, its top is fixedly installed blackboard 1, and bottom is equipped with pulley 3; The plate face of described blackboard 1 evenly arranges slide rail 11, hinged with one end of straight plate 5, set square 7, ruler 8 respectively by wing bolt 4 on described slide rail 11, the other end of wherein said straight plate 5 arranges through hole 6, and the other end of described ruler 8 is hinged with one end of short chi 10 by knob 9.
Wherein a kind of for mathematical education mapping blackboard, described straight plate 5, set square 7, ruler 8 and short chi 10, its material is specially plastics.
The utility model in use, the utility model is positioned in classroom, then teacher uses when mapping, need picture bowlder, then by wing bolt 4 is unscrewed, then straight plate 5 is moved to suitable mapping position, then tighten wing bolt 4 and straight plate 5 is fixed on correct position on slide rail 11, then chalk is inserted through hole 6, straight plate 5 is dragged respectively with wing bolt 4 for the mapping of picture circle is carried out in the center of circle by hand-held, when if desired using set square 7, then fix the position of set square 7 on slide rail 11 map by tightening or unscrewing wing bolt 4, if need picture straight line, line segment, then fix the position of ruler 8 on slide rail 11 map by tightening or unscrewing wing bolt 4, if during the curtailment of ruler 8, then by knob 9 short chi 10 rotated with ruler 8 linearly, then carry out mapping to use.
The utility model structure is simple, easy to use, easy to operate, easy to use, simple operation, solve during teacher's mathematics is given lessons and drawing tool cannot be made to fix at blackboard drawing and cause drawing efficrence to reduce, affect the problem of teaching quality, facilitate in teaching mathematical education process and map on blackboard, avoid mathematics teacher and carry the problem that many drawing tools increase labour intensity, practical reliable, improve drawing efficrence, save the class period.
