Abstract
The utility model relates to a multifunctional compass, belonging to a culture tool. The utility model is mainly composed of the center of a circle needle, a fixed sleeve, a band tape, a pen sleeve and a spring, and is characterized in that the center of the circle needle and the spring are installed in one side of the fixed sleeve through a screw. The band tape is installed in the fixed sleeve, and the other side of the fixed sleeve is provided with a stop button. The starting end of the band tape is fixedly connected with the pen sleeve. A small hole and a big hole are arranged on the pen sleeve, and the spring is installed in the big hole. The multi-function compass has the advantages of simple structure, convenient operation, quick circle drawing, and visual size of the drawing circle. The size of the adjustable range of the drawing circle is big, and the radius of the circle can be increased to 200 cm. The utility model is the multi-function compass which can draw circle and can also measure dimensions.
Description
The utility model relates to a kind of multifunctional compass, relates to a kind of compasses which is provided with tape measure and paintbrush device specifically, belongs to cultural tools.
At present, people are when design, construction or drawing, usually need to measure and draw circle, general survey tool is used tape measure, Steel Ruler etc. always, the instrument of drawing circle mainly is compasses, though and existing compasses it is simple in structure, use also more convenient, but its size of drawing circle is directly perceived inadequately, and often need utilize ruler that the bipod span of compasses is measured after the fixed length before drawing circle can programming; Also have, its magnitude range of drawing circle of existing compasses is little, the picture bowlder usually is subjected to the influence of compasses length, existing survey tool and circle tool are because its structural reason causes function singleness, in a word, in order to satisfy the needs of design and engineering construction etc., also need to design a kind of usefulness of both can having measured in the society, can draw roundly again, and draw the bowlder size multifunctional compass of one-object-many-purposes intuitively.
The purpose of this utility model just is to design a kind of simple in structure, which is provided with the multifunctional compass of tape measure and paintbrush device, to satisfy the needs of multiple occasions such as design and engineering construction.
The purpose of this utility model is achieved in that it mainly is made up of center of circle pin (1), fixed cover (2), tape measure (3), the pen cap (4), spring (5), it is characterized in that by screw (9) center of circle pin (1) and spring (5) being installed in the side of fixed cover (2), tape measure (3) is installed in the fixed cover (2), the opposite side of fixed cover (2) is provided with drag knob (6), the top head of tape measure (3) and the pen cap (4) are affixed, the pen cap (4) is provided with aperture (7) and macropore (8), and spring (5) is installed in the macropore (8).
The utility model is compared with prior art: it is simple in structure, and is easy to use, and it is quick to draw circle, and it is directly perceived to draw the circle size, the adjustable size of drawing circle, and scope is big, and radius of circle can increase to 200cm, is a kind ofly both can draw circle, but the multifunctional compass of measurement size again.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model broken section structural representation.
Accompanying drawing 2 is a vertical view of the present utility model.
Accompanying drawing 3 is a left view of the present utility model.
Among the figure: 1, center of circle pin, 2, fixed cover, 3, tape measure, 4, the pen cap, 5, spring, 6, drag knob, 7, aperture, 8, macropore, 9, screw.
As can be seen from the figure, the utility model it mainly by center of circle pin 1, fixed cover 2, tape measure 3, the pen cap 4, spring 5 is formed, by screw 9 center of circle pin 1 and spring 5 are installed in one side of fixed cover 2, starting point when described center of circle pin 1 is mainly used in as measurement or the center of circle fixed point of drawing bowlder, tape measure 3 is installed in the fixed cover 2, the opposite side of fixed cover 2 is provided with drag knob 6, the top head and the pen cap 4 of tape measure 3 are affixed, the pen cap 4 is provided with aperture 7 and macropore 8, spring 5 is installed in the macropore 8, utilize macropore 8, but spring 5 and aperture 7 plug-in mounting paintbrushes, can make things convenient for intuitively from the distance at the tip of paintbrush center to center of circle pin 1 and to read, that is to say that the reading on the tape measure 3 can directly measure the size of distance and radius of circle from tape measure 3.
During use, press center of circle pin 1 and paintbrush is inserted in the macropore 8, the pulling pen cap 4 and the size that can observe radius of circle on the tape measure 3 can the picture circles and measure.
