Abstract
The utility model provides a novel ruler, which comprises a ruler body with scales, wherein one end of the ruler body is structurally semi-circular in shape; the scales for angle measurement are formed on the circumference of the semi-circle; a plurality of pen holes are formed at the center of the semi-circle and formed at intervals at the center of the semi-circle along the length direction of the ruler body; and a plurality of long hollow grooves parallel to the length direction of the ruler body are formed at intervals on the ruler body. The novel ruler has the advantages of reasonable design, simple structure and convenient use, and can be conveniently used for measuring lengths and angles and drawing circles and parallel lines, so that the novel ruler has good popularization and use values.
Description
1, technical field
The utility model relates to a kind of survey tool, specifically a kind of protractor and simple and easy novel ruler of making the sired results tool of having.
2, background technology
At present, widely used ruler is to engrave scale on transparent blade, measures the distance of point-to-point transmission by the scale on the blade, draws straight line by blade.
But in the present measurement operation, often need draw circles, take measurement of an angle and be depicted as the straight line of certain angle.This draws with regard to other instruments such as needs cooperation compasses, protractors and measures.But use multiple instrument like this, strengthened the difficulty of drawing and measuring.Particularly for the student, it is avoidable fully assorting all drawing and survey tool.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of novel ruler that can be convenient for measuring length, angle and draw circles and parallel lines is provided.
The technical solution of the utility model realizes that in the following manner a kind of novel ruler comprises the blade that has scale, and its structure is that blade one end is the semicircle protractor that takes measurement of an angle.In the semicircle center hole is set, is arranged at intervals with a plurality of holes in the semicircle center along the blade length direction, these hole sites are corresponding with the long graduation mark on the blade.On blade, be arranged at intervals with many vast sky grooves parallel with the blade length direction.
The utility model has the advantages that:
1, is provided with semicircle protractor at blade one end, is convenient for measuring angle;
2, by a hole of semicircle center and its elsewhere, can conveniently draw the circle of certain radius;
3, by the vast sky groove on blade edge and the blade, can conveniently draw parallel lines.
4, description of drawings
Accompanying drawing 1 is a kind of structural representation of novel ruler.
Mark in the accompanying drawing is represented respectively: blade 1, graduation mark 2, a hole 3, vast sky groove 4.
5, the specific embodiment
Below in conjunction with accompanying drawing a kind of novel ruler of the present utility model is done following detailed description the in detail.
As shown in Figure 1, a kind of novel ruler of the present utility model, the blade 1 left end semicircular in shape having scale is carved with the graduation mark 2 that takes measurement of an angle in semicircular circumference.
In the semicircle center hole 3 is set, determines the both sides intersection point at angle by this hole.
Be arranged at intervals with a plurality of holes 3 in the semicircle center along the blade length direction, each hole 3 is all corresponding with long graduation mark on the blade 1.When the hole 3 in the fixing semicircle center of circle, penholder is gone into other holes 3 just can draw the circle that radius is an integer.
On blade 1, be arranged at intervals with many vast sky grooves 4 parallel, can draw parallel lines by these vast sky grooves 4 with the blade length direction.
A kind of novel ruler of the present utility model is reasonable in design, simple in structure, easy to use, thereby, have good value for applications.
