Abstract
The utility model is formed in the way that a main ruler with an angulometer is connected with the other subsidiary ruler by a rotary shaft, and the rotary shaft is provided with an indication line. The utility model has the functions of straight rulers, triangular plates and angulometers. The utility model has the advantages of small size, convenient use and portability.
Description
The utility model belongs to the drawing instrument field, particularly a kind of multifunctional drawing ruler.
Existing drawing appliance purposes is single, in use needs repeatedly to make up, and not only increases unnecessary workload, also loses time, and brings inconvenience to working and learning.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of multifunctional drawing ruler of drawing out multiple picture shape is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of multifunctional drawing ruler, it is characterized in that flexibly connecting by a rotating shaft and a secondary chi with the main scale of angulometer, rotating shaft is positioned on the center of circle of the main scale of being with angulometer, and an index line is arranged, and the main scale of band angulometer and the graduation mark position of secondary chi be rightabout each other.The end of secondary chi has a boss.
The utility model can reach multiple mapping functions such as ruler, angulometer, set square, and volume is little, is easy to carry, and is easy to use, is suitable for working and learning.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is connected by the secondary chi 2 of rotating shaft 3 and another by the main scale 1 of a band angulometer, and rotating shaft 3 is positioned on the center of circle of being with angulometer main scale 1 and an index line 4 is arranged.When using with set square or angulometer, will be with the main scale 1 of angulometer to maintain static, make secondary chi 2 rotate and support by boss 5, corresponding with the angulometer graduation mark on the main scale 1 by index line 4, the required angle that can measure or draw is come; When using with ruler, main scale 1 and secondary chi 2 merged or change into 180 °, straight line or measure the distance of straight line then can draw.Scale on two straight lines is positioned at different azimuth and can be convenient to measure.
