Abstract
The utility model relates to a drawing instrument especially relates to a convenient multi-functional compasses. The compasses are characterized in that one end of a graduated scale is provided with a fixed end component, a ruler body of the graduated scale is provided with a sliding component which can slide, the fixed end component and the sliding component are respectively provided with a line drawing device, and the graduated scale is marked with length scales. The compasses have the functions of compasses and a ruler. Compared with the existing compasses, the compasses have the advantages of simple structure, wide application, high drawing precision, convenient use and the like.
Description
The utility model relates to a kind of drawing instrument, relates in particular to a kind of convenient multi-functional compasses.
Existing compasses kind is more, but these compasses all exist an identical shortcoming, can not directly determine drawn radius of a circle exactly, must measure with ruler, it is very inconvenient for the user, and has complex structure, shortcomings such as Drawing Error is big, and purposes is single.
To be that design is a kind of have simple in structurely the purpose of this utility model, and purposes is many, cartographic accuracy height, the compasses of advantage such as easy to use.
The utility model is realized by following technical scheme: the feature of this compasses is that the end at rule is provided with the stiff end assembly, on the blade of rule, be provided with a slide assemblies that can slide, on stiff end assembly and slide assemblies, be respectively equipped with line-plotting device, be marked with the length scale at rule.The stiff end assembly is fixed, and main effect is the fixing parts of line-plotting device, and slide assemblies can arbitrarily slide on rule, also can be removed, and also is fixed with the parts of line-plotting device on slide assemblies.Line-plotting device is the device of picture circle and circular arc, and it mainly comprises pilot pin and detail pen.Pilot pin and detail pen are separately fixed on stiff end assembly and the slide assemblies, and preferably pilot pin is fixed on the slide assemblies, and detail pen is fixed on the stiff end assembly.In order to make these compasses more convenient in use, accurate, to be preferably in a clamp assembly is set on the slide assemblies, clamp assembly can make slide assemblies arbitrarily fixing, thereby nonvoluntary slip produces error when guaranteeing the picture circle or drawing circular arc.Clamp assembly can adopt versions such as spring, screw, rubber blanket all can.
During use, draw circle or draw arc with these compasses, catch the stiff end assembly of rule one end, slide assemblies on the rule again slides, determining the radius of drawn circle or circular arc, move clamp assembly again and fix slide assemblies, is the center of circle with the pilot pin, with setting-out stroke circle or picture arc, can obtain required circle or circular arc.When needing picture straight line or measuring distance, slide assemblies can be unloaded down, just can make ruler with rule and use.
This compasses have the function of compasses and ruler, in use can directly read the radius size of drawn circle or circular arc, thereby it and existing compasses are relatively, have simple in structurely, and purposes is wide, cartographic accuracy height, advantage such as easy to use.
Fig. 1 is the structural representation of convenient multi-functional compasses of the present utility model.
Be described in detail below in conjunction with accompanying drawing.
In the accompanying drawing: 1 stiff end assembly; 2 slide assemblies; 3 rules; 4 line-plotting devices; 5 pinching screws; 6 line-plotting device fixed knobs; 7 handles.
Stiff end assembly (1) is fixed on the end of rule (3), slide assemblies (2) is positioned on the blade of rule (3), can arbitrarily slide, be respectively equipped with line-plotting device (4) on stiff end assembly (1) and slide assemblies (2), line-plotting device (4) mainly comprises pilot pin and detail pen.For slide assemblies (2) can arbitrarily be fixed, on slide assemblies (2), be provided with a clamping device (5).Line-plotting device fixed knob (6) is stationary positioned pin and detail pen.
Claims (2)
1, a kind of convenient multi-functional compasses, it is characterized in that being provided with the stiff end assembly at an end of rule, on the blade of rule, be provided with a slide assemblies that can slide, on stiff end assembly and slide assemblies, be respectively equipped with line-plotting device, be marked with the length scale at rule.
2, convenient multi-functional compasses according to claim 1 is characterized in that being provided with a clamp assembly on slide assemblies, make slide assemblies arbitrarily fixing.
