Abstract
A drawing ruler for teaching belongs to the drawing appliance for teaching, which is characterized in that one side of a straight ruler is provided with a hanging hole, the other side thereof is provided with a moving rule clamp notch, and the center of the straight ruler is provided with a protruded shaft; the straight ruler on the back of the protruded shaft is provided with a concave hole, the edge of the straight ruler under the protruded shaft is provided with a protractor integrated with the straight ruler; the protruded shaft is movably connected with the moving ruler; the body of the moving ruler is provided with 3 to 5 through holes; and both the straight ruler and the moving ruler are provided with scale marking lines. The utility model has simple structure, is convenient to use, has multifunction, and avoids the trouble that the teacher needs taking more drawing tools when teaching. When in use, the drawing ruler can be used as a straight ruler, also can be used to measure angle, when needing drawing a circle, the teacher can install a slightly-protruded chalk in the concave hole on the back of the protruded shaft, then place the chalk into the through hole of the moving ruler, and rotate the moving ruler.
Description
Technical field:
The utility model belongs to teaching drawing appliance, particularly a kind of mathematics drawing rule.
Background technology:
The present drawing appliance that uses in the teaching, such as function singleness mostly such as ruler, protractor, compasses, therefore in teaching, the teacher teaches and often will carry more drawing appliance, uses inconvenience.
The utility model content:
The utility model overcomes the deficiency of the problems referred to above, provide a kind of simple in structure, multi-functional mathematics drawing rule easy to use, this mathematics is achieved in that with drawing rule the side at ruler is provided with hanging hole, the opposite side of ruler is provided with moving chi bayonet socket, be provided with prominent axle in the center of ruler, on the ruler at the prominent axle back side, be provided with shrinkage pool, on the ruler edge under the prominent axle, be integrally formed with protractor with ruler, on prominent axle, be connected with moving chi, on the chi body of moving chi, be provided with 3-5 moving chi through hole, be equipped with the graduated scale timberline on said ruler and the moving chi.
The utility model is simple in structure, and is easy to use, and the many usefulness of a chi have saved the trouble that the teacher teaches and carries more drawing tool.Can make ruler during use and use, also the size that can take measurement of an angle needs the picture bowlder, and the outstanding slightly chalk of packing in the shrinkage pool at the prominent axle back side earlier is placed into chalk in the moving chi through hole then, revolves rotary ruler and gets final product.
Description of drawings:
The specific embodiment:
In conjunction with the accompanying drawings 1 and accompanying drawing 2 embodiment be: a kind of mathematics is achieved in that with drawing rule the side at ruler 2 is provided with hanging hole 1, the opposite side of ruler 2 is provided with moving chi bayonet socket 5, be provided with prominent axle 3 in the center of ruler 2, on the ruler 2 at prominent axle 3 back sides, be provided with shrinkage pool 8, on ruler 2 edges under the prominent axle 3, be integrally formed with protractor 4 with ruler 2, on prominent axle 3, be connected with moving chi 6, on the chi body of moving chi 6, be provided with 3-5 moving chi through hole 7, be equipped with the graduated scale timberline on said ruler 2 and the moving chi 6, protractor 4 is provided with angle and indicates line.
The utility model is simple in structure, and is easy to use, and the many usefulness of a chi have saved the trouble that the teacher teaches and carries more drawing tool.Can make ruler during use and use, also the size that can take measurement of an angle needs the picture bowlder, and the outstanding slightly chalk of packing in the shrinkage pool at the prominent axle back side earlier takes out moving chi in the driven then chi bayonet socket, chalk is placed in the moving chi through hole, revolves rotary ruler and gets final product.
