Abstract
The utility model discloses a multifunctional set square used for mathematics teaching, which comprises a ruler. The multifunctional set square is characterized in that a first sliding ruler and a second sliding ruler are arranged respectively at the two ends of the ruler in a rotating mode, a free end of the first sliding ruler and a free end of the second sliding ruler are connected together through a fastening screw, chutes are arranged on both the first sliding ruler and the second sliding ruler, an angle measuring instrument is arranged at one end of the ruler, and chalk sleeves used for fixing chalks are arranged at the ends of the first sliding ruler or the second sliding ruler. The multifunctional set square used for the mathematics teaching is simple in structure, reasonable in design, convenient to carry, convenient for teaching, and capable of integrating functions, such as drawing of angles, lines and circles and functions of angle measurement and the like and removing burdens of teachers.
Description
Technical field
The utility model relates to the teaching aid technical field, and specifically a kind of mathematical education is used multi-functional triangular ruler.
Background technology
At present, set square is one of indispensable teaching aid in the mathematical education, and in mathematical education, not only will use set square, also need use teaching aids such as ruler, angel measuring instrument and compasses.In existing teaching process, these teaching aids generally are independently individual respectively, and teacher need carry separately when giving lessons, and uses separately, and so not only complex operation, and easy the omission influences teaching efficiency easily.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of the utility model is to provide, and it is one that collection is drawn functions such as angle, straight line, picture circle and angular surveying, is convenient for carrying and imparts knowledge to students, and the mathematical education that can alleviate teacher's burden is used multi-functional triangular ruler.
In order to reach above purpose; The technical scheme that the utility model adopted is: mathematical education is used multi-functional triangular ruler; Comprise ruler; It is characterized in that: the two ends of said ruler are rotated respectively and are provided with the first slip chi and the second slip chi, and the free end of the first slip chi and the second slip chi links together through trip bolt, are equipped with chute on the first slip chi and the second slip chi; One end of said ruler is provided with angel measuring instrument, and the end of the said first slip chi or the second slip chi is provided with the chalk sleeve that is used for fixing chalk.
The utility model is also implemented through following measure: said ruler is a telescopic structure.
Said angel measuring instrument and ruler are rotatably connected.
The beneficial effect of the utility model is: simple in structure, reasonable in design, it is one that collection is drawn functions such as angle, straight line, picture circle and angular surveying, is convenient for carrying and imparts knowledge to students, and has alleviated teacher's burden.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing; Mathematical education is used multi-functional triangular ruler; Comprise ruler 1; The two ends of said ruler 1 are rotated the free end that is provided with the first slip chi 2 and the second slip chi, 3, the first slip chis 2 and the second slip chi 3 respectively and are detachably connected through trip bolt 4, are equipped with the chute 5 that is used for relative motion on the first slip chi 2 and the second slip chi 3; One end of said ruler 1 is provided with angel measuring instrument 6, and the end of the said first slip chi 2 or the second slip chi 3 is provided with the chalk sleeve 7 that is used for fixing chalk.
Said angel measuring instrument 6 is rotatably connected with ruler 1.Be convenient to draw the angle of various angles through this structure, be convenient to measure and use.
During use, the utility model is placed on the blackboard, can draws straight line through ruler 1; Can take measurement of an angle through angel measuring instrument 6, draw the angle through the first slip chi 2 and the angle that ruler 1 forms then; Can regulate the relative position of the first slip chi 2 and the second slip chi 3 as required through chute 5, thereby realize the set square of different angles, make things convenient for teacher's use of imparting knowledge to students; Through trip bolt 4 free end of the first slip chi 2 and the second slip chi 3 is taken apart, the chalk sleeve that is used for fixing chalk 7 that is provided with of the end through the first slip chi 2 and the second slip chi 3 is used for draw circles like this, and is to use as compasses, easy to use.
The utility model is simple in structure, and is reasonable in design, and it is one that collection is drawn functions such as angle, straight line, picture circle and angular surveying, is convenient for carrying and imparts knowledge to students, and alleviated teacher's burden.
