Abstract

The utility model provides a drawing ruler. An oblong slotted hole is formed in the bottom surface of the drawing ruler; an arch-shaped reed is fixed in the slotted hole; the reed can sink into a slot through being pressed, so that the bottom of the ruler sticks to the paper surface; therefore, a ruler body can be prevented from sliding to affect a scribing bar. During using, the bottom surface of the ruler can leave away from the paper surface for a certain distance under the supporting of the reed; and during moving the ruler body, wet ink points can be effectively avoided, so that a purpose of preventing the bottom surface of the ruler from being attached with ink to smudge the paper surface is achieved.

Description

Drawing rule

Technical field

The utility model relates to a kind of stationery, and specifically a kind of student draws and uses chi.

Background technology

Nowadays, common student uses drawing rule, and is mostly made of plastic, uses easily; But when drawing, tend to stay not dried ink dot with pen, after drying up again drawing can influence drawing efficiency; If do not note with regard to the attachable mechanical stage body, owing to be the plane at the bottom of the chi, therefore; Can dye the not dried ink on the pen lines just painting under, and along with the moving of chi body, infection is on whole paper; Accidentally can dye paper tacky, have to sometimes paint again, very trouble.

Summary of the invention

In order to overcome the above-mentioned deficiency of drawing rule, this practicality newly provides a kind of drawing rule, and this drawing rule is provided with leaf arrangement, can leave paper one segment distance at the bottom of making chi, avoids the chi bottom surface to contact with not dried ink, thereby avoids chi when mobile, to dye dirty paper.

The technical measures that its technical problem of the utility model solution is taked are to open rectangular slotted eye in the drawing rule bottom surface, clip device in slotted eye; Reed adopts metal to process, and reed archwise one end is fixed, and its fixed method adopts screw tightening; Perhaps fix in the end of an end of reed heating back insertion groove, perhaps be bonded in the end of groove with the end of glue with reed, the other end of reed does not fix; As free end, the free end of reed can freely stretch in groove, and the arching of reed a little is higher than the plane at the bottom of the chi; The length that is shorter in length than slotted eye of reed is pressed making leaf spring, and reed can be sunken in the groove; Be lower than the plane at the bottom of the chi after it arches and a little pushes, be close to paper at the bottom of making chi, can avoid the chi body to slide and influence line bar.During use, under the support of reed, paper one segment distance can be left in the chi bottom surface; When the attachable mechanical stage body, can effectively avoid not dried ink dot, need not to dry up drawing again behind the ink marks, and when needing attachable mechanical stage; As long as stir the chi body gently; Will under the slip of reed, easily be shifted, and paper can not run in the chi bottom surface, avoids the chi bottom surface to dye the purpose that China ink is made paper dirty thereby reach.

The beneficial effect of the utility model is, improved the quality and the efficient of drawing, and is simple in structure.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the structural representation of drawing rule.

Fig. 2 is the structural representation of drawing rule leaf arrangement.

In Fig. 1 and Fig. 2,1. drawing rule, 2. bottom surface, 3. slotted eye, 4. leaf arrangement, 5. screw, 6 arch a little.

The specific embodiment

In the figure,? Foot 1 foot in the drawing to open rectangular slot bottom 2 3? Catching rabbits installed in slot 4 of a reed,? Reeds made of metal,? Reed into a bow end fixed,? Fixed The method of using the tightening screw 5,? or the heated end of the reed in one end of the insertion slot is fixed,? or glue stick one end of the blades in one end of the groove,? the other end of the spring is not fixed in the groove the free stretch? reed point 6 above the foot end of the bow plane,? reed shorter in length than the length of the slot,? after pressing the bow point 6 below the foot bottom plane 2.

Claims

1. drawing rule is characterized in that: rectangular slotted eye is opened in the bottom surface at existing drawing rule, fixing arc reed in slotted eye; One end of reed is fixed, and the other end of reed does not fix, as free end; The free end of reed can freely stretch in groove, and the arching of reed a little is higher than the plane at the bottom of the chi, the length that is shorter in length than slotted eye of reed; Press making leaf spring, reed can be sunken in the groove, is lower than the plane at the bottom of the chi after it arches and a little pushes.

2. drawing rule according to claim 1 is characterized in that: said reed adopts metal to process.

3. drawing rule according to claim 1 is characterized in that: its fixed method adopts screw tightening, perhaps fixes in the end of an end of reed heating back insertion groove, perhaps is bonded in the end of groove with the end of glue with reed.
