Abstract
The utility model belongs to a pair of improved compasses of drawing tools. The utility model comprises a neck handle, a compass body, two compass legs, a needle and a pen head. The utility model is characterized in that a rule is transversally arranged at the same height of the middle sections of the compass legs; one end of the rule is connected with one of the compass legs through a positioning nail; the rule is provided with a long slot guide hole along the axial direction; an indicating nail with an indicating cusp lead the rule to be in a pin link with the other compass leg through the long slot guide hole; the indicating nail and the long slot guide hole can correspondingly slide; the rule is provided with scales along the direction of the long slot guide hole.
Description
The utility model belongs to the improvement invention of drawing instrument compasses.
The compasses that generally use in existing people's life are to be linked to be together through the rule body by two rule legs, are provided with the neck handle on the rule body, establish pin and nib (pencil-lead or duckbilled nib) on the rule leg.Though the internal structure of rule body has the function of multiple variation or compasses to increase, for example Chinese patent 90203294.1, still do not appear at the compasses that show radius of a circle length numerical value when drawing circle at present.
The purpose of this utility model provides a kind of scale compasses that can indicate radius of a circle length numerical value at stroke bowlder.
The purpose of this utility model is finished by following technical scheme: it comprises neck handle, rule body, two rule leg, pin and nibs, stage casing sustained height at described two rule legs is horizontally set with a scale, this scale is along laterally being provided with scale, its one is connected through locating pin with rule leg wherein, and the other end has the indication nail of indicate tip by one and is positioned on the another rule leg and slippage cooperation mutually.
Above-mentioned scale can be ruler, also can be shapes such as arc chi.Scale can have multiple mounting means to change through indication nail and rule leg, as long as slippage mutually.Example: above-mentioned indication nail can be positioned on the edge of scale, and scale is stuck on the rule pin; Or offering the elongated slot guide hole vertically at described scale, above-mentioned indication nail is positioned on this scale on the rule leg by this elongated slot guide hole.
Above-mentioned locating pin can make scale affixed with the rule leg, also can be hinged, if hinged, then the elongated slot guide hole of scale has a deep-slotted chip breaker for the preparation of indication nail in the side near the locating pin place, when two rule legs pressed from both sides, the indication nail entered this deep-slotted chip breaker, and scale can rotation.Or offer arc-shaped slot in the locating pin junction of said scale, give up the throne for locating pin.
The indication point that above-mentioned indication nails on can be done the forming shape tip, also can be the color pattern tip.
Principle of the present utility model is: because scale is in the sustained height of two rule legs, so the first half isosceles triangle is similar to the big isosceles triangle that 2 rule legs (same length) and paper are formed, then length and the radius of a circle between locating pin and indication nail is proportional on the scale, and promptly the numerical value of indication tip is directly proportional with the circle footpath on the scale.
The utility model is because of having scale, and compasses can be read length numerical value from the scale label of indication tip indication when using, promptly known radius of circle length numerical value.If establish the arc slotted eye on scale, then compasses can draw in.
Fig. 1 is the structural representation of technical solutions of the utility model embodiment
Further describe embodiment below in conjunction with accompanying drawing: left side rule leg 3 is connected through rule body 2 with right compass leg 7, and can separately press from both sides, and rule body 2 is provided with neck handle 1.Left side rule leg 3 lower end stationary positioned pins 6, fixing nib (pencil-lead or ruling pen) on the right compass leg 7.Establish a scale 9 at the stage casing of right compass leg and right compass leg sustained height.Also have an elongated slot guide hole on the scale 9 vertically, indication nail 8 with indication tip 10 sells even scale 9 and above-mentioned right compass leg 7 by this elongated slot guide hole, indication nail 8 can slide relatively with the elongated slot guide hole, and scale upper edge elongated slot guide hole direction is arranged with the length scale.The left end of scale 9 is offered downward arc slotted eye 5, one location pins 4 connects scale 9 and left side rule leg 3 pins by this arc slotted eye 5, when two rule legs press from both sides, locating pin 4 enters this arc slotted eye 5 bottoms, makes the scale can rotation, when compasses draw in like this, scale also can draw in rotation, is convenient to harvesting.
Claims (4)
1, a kind of scale compasses, comprise neck handle (1), rule body (2), two rule legs (3,7), pin (6) and nibs (11), it is characterized in that: be horizontally set with a scale (9) at described two sustained heights of advising the stage casing of legs, this scale is along laterally being provided with scale, its one is connected through locating pin with rule leg wherein, and the other end has the indication nail of indicate tip by one and is positioned on the another rule leg and slippage cooperation mutually.
2, scale compasses as claimed in claim 1, it is characterized in that: described scale offers the elongated slot guide hole vertically, and above-mentioned indication nail is positioned on this scale on the rule leg by this elongated slot guide hole.
3, scale compasses as claimed in claim 2 is characterized in that; Above-mentioned locating pin and described scale are hinged, and the elongated slot guide hole of described scale is having a deep-slotted chip breaker for the preparation of indication nail near locating pin place one side, and the indication nail enters this deep-slotted chip breaker when two rule legs press from both sides, and scale can rotation.
4, scale compasses as claimed in claim 2 is characterized in that: offer arc-shaped slot (5) in the locating pin junction of said scale.
