Abstract
The utility model discloses a convenient multipurpose ruler which comprises a straight ruler on which an angulometer is fixed. An angle indicating device for indicating an included angle formed by the straight ruler and a perpendicular line or the straight ruler and a horizontal line is arranged on the angulometer. The straight ruler is also provided with at least two holes for drawing circles. Straight lines of various angles, parallel lines, circles, etc. can be conveniently drawn by the angle indicating device when the straight ruler is rotated on a vertical plane or a horizontal plane. The utility model has the advantages of simple structure, multiple functions of one ruler, and high drawing accuracy. The convenient multipurpose ruler can be used for teaching or other occasions.
Description
Technical field
The utility model relates to the drawing instrument field, and is particularly a kind of for the convenient multi-purpose chi of imparting knowledge to students or the student uses.
Background technology
The drawing instrument of at present common be used for picture straight line or angle is nothing more than the drawing instrument of ruler, set square, protractor, compasses and so on, these instrumental functions are single, during drawing, very simple oblique line or parallel lines, also needing to use a plurality of drawing instruments just can finish, not only operation inconvenience, and precision can not guarantee.
Summary of the invention
The task that this reality is new is a kind of easy to use, precision is high and function is many convenient multi-purpose chi of design.
The novel technical scheme of this reality is:
A kind of convenient multi-purpose chi comprises a ruler, it is characterized in that described ruler is provided with a circular angulometer, is provided with the angle indicating device that is used to refer to ruler and vertical line or ruler and horizontal line angle on angulometer.
Described indicating device is a pointer, and the centre of pointer is by on the center of circle that is connected described angulometer free to rotately, and an end of pointer is connected with heavy ball.
Described indicating device can also be another kind of version, and it comprises that one is located on the described angulometer and concentric with it pipe, is filled with liquid in the pipe, is provided with minute bubbles that are used to refer to the ruler angle of inclination in the liquid.
Also has a compass that is located on the described circular angulometer center of circle on the above indicating device.
The above its length direction of ruler upper edge is provided with at least two circular holes that are used for the picture circle.
The utility model has the advantages that simple in structure, function is many, easy to use and precision is high.As shown from the above technical solution, only utilize the utility model ruler, just can in horizontal or vertical, draw various oblique lines or survey its angle by protractor on it and the shown angle of indicating device.Utilize scale on the ruler and the circular hole circle of multiple diameter that then can draw; In conjunction with both, various complex figures can draw.
Description of drawings
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is the schematic diagram of the another kind of embodiment of the utility model;
Fig. 3 utilizes convenient multi-purpose chi shown in Figure 2 to draw the schematic diagram of oblique line;
Fig. 4 utilizes convenient multi-purpose chi shown in Figure 2 to draw the schematic diagram of circle;
Fig. 5 is the schematic diagram of another embodiment of the present utility model.
The specific embodiment
A kind of convenient multi-purpose chi (as shown in Figure 1), it comprises a ruler 1, ruler 1 is provided with a circular angulometer 2.On angulometer 2, be provided with the angle indicating device 3 that is used to refer to ruler and vertical line or ruler and horizontal line angle.Indicating device 3 is a pointer 31 specifically, and the centre of pointer is by on one 32 center of circle that is connected described angulometer 2 freely to rotate, and an end of pointer 31 is connected with a heavy ball 33.
This makes things convenient for multipurpose ruler is pointer-type, and circular angulometer and ruler are fixed together, and how many angles ruler turns over, and pointer just refers to just can make horizontal line easily on blackboard with it according to this principle on how many degree, draws parallel lines, and takes measurement of an angle.
Embodiment 2:
This makes things convenient for multipurpose ruler is bubble type (shown in Fig. 2,3).It comprises a ruler 1, and ruler 1 is provided with a circular angulometer 2.On angulometer 2, be provided with the angle indicating device 3 that is used to refer to ruler and vertical line or ruler and horizontal line angle.
Indicating device 3 specifically, it comprises a pipe 4 concentric with angulometer 2, is filled with liquid 41 in the pipe 4, and minute bubbles 42 are arranged in the liquid.When ruler 1 rotated, bubble 42 was because the effect of gravity is in the top of pipe 4 all the time, and how many angles ruler 1 turns over, and how many angles bubble 42 just refers on.Its length direction of ruler upper edge is provided with at least 6 circular holes 6 that are used for the picture circle.Utilize any one circular hole to do the center of circle, the another one circular hole is made radius then can draw circle (as shown in Figure 4).
Embodiment 3:
The difference of present embodiment and front embodiment is that indicating device 3 comprises that also one is located at the compass 5 (as shown in Figure 5) of indicated North and South direction on circular angulometer 2 centers of circle, that make with small magnetic needle, utilizes compass can draw out various figures more easily on horizontal plane.
