Described supporting leg and center of circle positioning device are all equipped with safety protection jacket, prevent that its wedge angle from damaging people.
The beneficial effects of the utility model are: the displayable large-scale round instrument of painting of a kind of radius, it can directly read arc or circular radius value by display, thereby can directly calculate other parameter of circle or circular arc, facilitate the drafting of large-scale circle or circular arc, simplified drawing step, easy to operate, setting-out is accurate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the displayable large-scale structural representation of painting round instrument of a kind of radius.
Accompanying drawing 2 is the electromagnetic induction label placement figure on dimension line.
In figure, 1. winding box, 2. spool, 3. handle, 4. supporting leg, 5. dimension line, 6. electromagnetic induction counter, 7. line outlet, 8. card line button, 9. battery, 10. electronic console, 11. center of circle positioning devices, 12. electromagnetic induction marks.
The specific embodiment
In the accompanying drawings, the displayable large-scale round instrument of painting of a kind of radius, comprises winding box 1, and the bottom surface of winding box 1 is provided with supporting leg 4; Described winding box 1 inner bearing is connected with spool 2, and spool 2 is stretched out and is provided with handle 3 by winding box 1 top, and the sidewall of winding box 1 is provided with line outlet 7, and line outlet 7 places are provided with electromagnetic induction counter 6 and card line button 8; On described spool 2, be wound with dimension line 5, one end of dimension line 5 is fixedly connected with spool 2, the other end stretches out line outlet 7 and connects center of circle positioning devices 11, uniform along its length on dimension line 5 can be by the electromagnetic induction mark 12 of electromagnetic induction counter 6 induction identifications; The end face of described winding box 1 is provided with electronic console 10, and bottom surface is provided with battery case, and battery 9 is installed in battery case; Battery 9 is connected with electronic console 10 and electromagnetic induction counter 6 respectively, for they provide operating voltage, and electronic console 10 and 6 connections of electromagnetic induction counter.
The dimension mark that is accurate to millimeter is set on described dimension line 5, and size zero flag is positioned on the axis of center of circle positioning device 11.
Interval 1cm between two adjacent electromagnetic induction marks 12.
Described card line button 8 is connected with the snug engagement of winding box 1, can seal line outlet 7, fixed dimension line 5.
