In addition, this compass is able to directly measure a radius and an angle of an arc to be drawn and, therefore, convenient to use.SELECTED DRAWING: Figure 1

Description

本発明は文具技術分野に関わり、具体的には角度を自動的に測れるコンパスである。 The present invention is related to the field of stationery technology, and specifically, is a compass that can automatically measure an angle.

今までのコンパスは支持脚の下端にはただ尖頭を設置し、円弧の円心を定位し、それによって絵を書く時、手が支持脚に与える圧力が増える時、尖頭が画紙を突き通す恐れがあり、そのほか、図画ロッドを手で引っ張って調節し、即時ロック装置を設置していないため、絵を書く時、図画ロッドが滑って移動しやすく、円弧を書くのは順調ではなく、且つ円弧の角度を直接に測ることができなく、従って、既存の技術の中のコンパスを改善し、それによってコンパスの使用の便利さを高める。 Traditional compasses simply place a cusp at the bottom of the support leg to localize the circular center of the arc, which causes the cusp to hold the drawing paper when drawing, when the pressure exerted by the hand on the support leg increases. In addition, there is a risk of piercing, and since the drawing rod is adjusted by pulling it by hand and no immediate lock device is installed, the drawing rod slides easily when drawing a picture, and drawing an arc is not smooth. Moreover, the angle of the arc cannot be measured directly, thus improving the compass in existing techniques, thereby increasing the convenience of using the compass.

有益なように、前記取り付け装置３００は下方に開口した空き溝３７を含み、前記空き溝３７の中には下端が上記の絵を書く面と当接した芯３８がスライドできるように設置され、前記空き溝３７の右端壁の中には凹溝３９が連通するように設置され、前記凹溝３９の中には左端面が軟質で滑り防止パッドである挟みブロック４１がスライドできるように設置され、前記挟みブロック４１の左端が前記芯３８と当接しており、前記挟みブロック４１の右端にはネジ軸４２が回転できるように設置され、前記凹溝３９の右側にはネジ山溝４０が外部空間と連通するように設置され、前記ネジ軸４２の右端が前記ネジ山溝４０を貫通して外部空間に伸びており、
前記ネジ軸４２が回転し、挟みブロック４１を押し動かして左方へ移動させて芯３８をきつく挟む。 Beneficially, the mounting device 300 includes an open groove 37 that opens downward, and is installed in the open groove 37 so that a core 38 whose lower end is in contact with the drawing surface is slidable. A concave groove 39 is installed in the right end wall of the empty groove 37 so as to communicate with the concave groove 39, and a sandwich block 41 having a soft left end surface and an anti-slip pad is installed in the concave groove 39 so as to slide. The left end of the sandwiching block 41 is in contact with the core 38, the screw shaft 42 is installed at the right end of the sandwiching block 41 so that the screw shaft 42 can rotate, and the screw thread groove 40 is located on the right side of the concave groove 39 in an external space. The right end of the screw shaft 42 penetrates the thread groove 40 and extends to the external space.
The screw shaft 42 rotates and pushes and moves the sandwiching block 41 to move it to the left to tightly pinch the core 38.

初期状態の時、図画ロッド２４の左端面が支持脚４３の右端面と当接しており、針４９は零を指している。 In the initial state, the left end surface of the drawing rod 24 is in contact with the right end surface of the support leg 43, and the needle 49 points to zero.

作動する時、支持脚４３の下端が書く円弧の円心と重なり合い、支持ブロック５７の下端面が絵を書く面と当接し、それによってコンパスを使用する過程において、回転軸１１の圧力が支持ブロック５７に分けて当たり、支持脚４３の下端が絵を書く面を突き通すことを防止し、次に、捻りブロック２３を回転させてウォーム２１を回転連動させ、それによってウォームホイール２０が回転し、それによって図画ロッド２４が支持脚４３から離れている片側に回転し、それによってスライドロッド１４が右方へ伸び、変位センサー１７を右方へ移動連動させ、図画ロッド２４が回転した後に支持脚４３との間の水平移動の差を測り、この値はディスプレー１２を通じて示され、またその値は円弧の半径の長さであり、図画ロッド２４が回転している過程において、推しブロック２６がプレスロッド２７を押して下降させ、コンロッド（連通ロッド）３０によって連結ブロック３２が右方へ移動し、それによってペンホルダー３６が時計回り方向に回転し、且つペンホルダー３６と絵を書く面とを始終に垂直状態にさせ、その後、回転軸１１を回転させ、それによって回転ブロック１０が図画ロッド２４を回転連動させ、引き紐５２によってスライドブロック４８を連動させて環状溝４６に沿ってスライドさせ、それによって針４９が目盛盤４５に示す数字は円弧の角度である。 When activated, the lower end of the support leg 43 overlaps the circular center of the arc drawn, and the lower end surface of the support block 57 abuts the drawing surface, whereby the pressure of the rotating shaft 11 is applied to the support block in the process of using the compass. It is divided into 57 to prevent the lower end of the support leg 43 from penetrating the surface on which the picture is drawn, and then the twist block 23 is rotated to rotate the worm 21 so as to rotate the worm wheel 20. The drawing rod 24 rotates to one side away from the support leg 43, whereby the slide rod 14 extends to the right, the displacement sensor 17 moves to the right and interlocks with the drawing rod 24, and after the drawing rod 24 rotates, the slide rod 24 and the support leg 43 The difference in horizontal movement between the two is measured, this value is shown through the display 12, and the value is the length of the radius of the arc, and in the process of rotating the drawing rod 24, the pushing block 26 presses the rod 27. The connecting block 32 is moved to the right by the conrod (communication rod) 30 so that the pen holder 36 rotates clockwise and the pen holder 36 and the drawing surface are kept vertical from beginning to end. After that, the rotating shaft 11 is rotated, whereby the rotating block 10 rotates and interlocks the drawing rod 24, and the pull string 52 interlocks the slide block 48 and slides it along the annular groove 46, whereby the needle 49 is graduated. The number shown on the board 45 is the angle of the arc.

本発明の有益な効果は：本発明は構成が簡単で、操作が便利で、ウォームとウォームホイールとの自己ロックによって図画ロッドが伸びた後の位置は安定し、絵を書くことが誤差がなく正確であり、また絵を書く時、支持脚の下端には支持ブロックが設置され、支持脚に受けた圧力を減少し、画紙又は画板を傷つけることから守り、そのほか、このコンパスは書く円弧の半径と角度を直接に測ることができ、使用が便利である。 The beneficial effect of the present invention is: The present invention is simple to configure, convenient to operate, the self-locking of the worm and the worm wheel stabilizes the position after the drawing rod is extended, and there is no error in drawing. It is accurate, and when drawing a picture, a support block is installed at the lower end of the support leg to reduce the pressure applied to the support leg and protect it from damaging the drawing paper or drawing board. Besides, this compass has a writing arc. The radius and angle can be measured directly, which is convenient to use.
