Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ruler one.
Fig. 2 is ruler two structural representations of the present utility model.
In accompanying drawing: 1, ruler one; 2, scale; 3, rectangular window; 4, boss hole; 5, boss; 6, ruler two; 7, circular window; 8, groove; 9, perforation; 10, featheredge.
The specific embodiment
The utility model purposes: research work drawing tool, teaching aid, student appliance, ruler.
The utility model material therefor: transparent organic plastics or stainless steel.
The utlity model has on blackboard or on paper or on other object and control, make an arc, draw circle, draw the operations such as straight line, the feature of black trace is not stayed in pen picture bottom surface.The utility model is comprised of 2 two coaxial rulers, wherein in the middle of ruler one, has the window of certain specification, and ruler two leaves a plurality of hollow circular window that diameter does not wait.Between ruler, coaxial free-open-close is 90～180 °.With graduated three limits, thinning is at the bottom of periphery formation grooved a little, and such structure has advantages of that when pen is drawn, black trace is not stayed in bottom surface.
The utility model feature: use one, one, ruler fixing, for other end, circle etc. is made an arc arbitrarily, drawn to a tool such as chalk, pencil, signature pen; The open circles of the different-diameter on ruler two provides picture circle, makes an arc; Ruler is turned up and is convenient to control on blackboard or on paper or on other object, makes an arc, draws circle, draws the operations such as straight line, and black trace is not stayed in pen picture bottom surface.
Concrete technical scheme is as follows:
Ruler one specification.Ruler one specification is: length * wide * thick=20～100 * 3～5 * 0.1～0.3cm, ruler one surrounding is carved with a millimeter scale.The another side of ruler one is also carved with same millimeter scale.Two-sidedly all mark 1,2,3 ... centimetre numeral.
Rectangular window 3 specifications.In the middle of ruler, leave window, window specification is: length * wide=19～99 * 2～4cm, the degree of depth is with ruler thickness.
Ruler two apertures.Ruler two sides leave aperture, the side 0.2～0.5cm that aperture is nearest, and aperture diameter 0.05～0.15cm, is convenient to penetrate the steel wire of equivalent diameter, for being connected with the coaxial of ruler one.Groove 8 is left in one side centre position of ruler one.Groove 8 specifications: length * wide * thick=15～60 * 0.2～0.5 * 0.1～0.3cm.The tow sides of groove both sides ledge are erased corner angle.The side thickness that ruler one leaves aperture is constant, and its excess-three side thickness reduces, and is featheredge 10.Specification is: length * wide * thick=20～100 * 0.1 * 0.05～0.2cm, when pen is drawn like this, black trace is not stayed in bottom surface.
Ruler two specifications are: length * wide * thick=20～100 * 3～5 * 0.1～0.3cm, ruler two is carved with a millimeter scale.The another side of ruler is also carved with same millimeter scale.Two-sidedly all mark 1,2,3 ... centimetre numeral.On ruler two, have that the open circles of different-diameter is ascending is sequentially arranged in centre position or the gradually minispread of the large both sides of mid diameter open circles.Ruler two open circles diameter specifications 0.5～3.5cm, the degree of depth is identical with ruler two, 10～15 of quantity.
At ruler two, have Yi Ce centre position, aperture to leave boss 5, specification is: length * wide * thick=15～60 * 0.2～0.5 * 0.1～0.3cm, boss 5 is corresponding with the groove 8 of ruler, identical.The outside tow sides of boss 5 are erased corner angle.Boss 5 parts leave boss hole 4, and aperture diameter 0.05～0.15cm is convenient to penetrate the steel wire of equivalent diameter, for being connected with the coaxial of ruler one.
Multifunctional straightedge is that boss hole 5 is penetrated and is formed by connecting by coaxial steel wire with perforation 9.Steel wire diameter: 0.05～0.15cm.Ruler one is connected by steel wire with ruler two, free-open-close, and free-open-close angle is 90～180 °.
The utility model good effect: easy to operate, function is many, be convenient to measure, mapping, low cost of manufacture, is convenient to produce.One, ruler is fixing, and for other end, a tool such as chalk, pencil, signature pen is made an arc arbitrarily, drawn circle, draws intersection point etc.; The open circles of the different-diameter on ruler two provides picture circle, makes an arc.When ruler one is placed on drawing board, a hand mapping, another hand pinches ruler two, is convenient to change picture position.Ruler one and ruler two, with featheredge 10, are made an arc, are drawn circle, draw the operations such as straight line, and black trace is not stayed in pen picture bottom surface.
