Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the present embodiment provides a tool ruler with a chamfer structure, which includes a ruler body 1, a plurality of holes, an edge chamfer and a hole chamfer 32; the ruler body 3 is provided with a plurality of holes; the edge chamfer is arranged on the drawing edge of the ruler body 3; the hole chamfer 32 is arranged at the edge of the hole; the edge chamfer is a conical chamfer; the hole chamfer is a tapered step chamfer.
In this embodiment, the instrument chi of taking chamfer structure is used for all kinds of drawings in the military field to draw, and in the use, nib 11 marks through the hole of ruler body 3, draws through the drawing edge of ruler body 3 simultaneously.
In the embodiment, the ruler body 3 is a main body part of the tool ruler with the chamfer structure, and various holes are formed in the ruler body 3 and used for military marking; wherein the holes are hole sites; the number of the holes is 15-50; the thickness of the ruler body 3 is 2.5 mm.
In this embodiment, the edge of the hole is in contact with the pen tip 11 of the drawing pen 1 used for drawing, and the pen tip 11 penetrates through the hole to draw on the drawing paper 2.
In this embodiment, the hole chamfer 32 is used for realizing the complete separation of the pen point 11 and the hole, so that the printing ink on the pen point 11 cannot pollute the drawing when drawing the drawing, and meanwhile, the drawing precision is guaranteed not to deviate.
In this embodiment, the edge chamfer is used for realizing that 3 marginal complete breakouts from of nib and ruler body, and then makes when drawing along the drawing edge of ruler body with the ink pen, on the ink can not permeate the paper along the drawing edge of ruler, and after the upset, the nib of ink pen is unsettled, does not contact ruler body and paper to can not pollute the drawing, simultaneously, the precision that above-mentioned setting also can guarantee to draw the drawing does not produce the deviation.
In the embodiment, the conical chamfer forms an angle between the edge of the ruler body and the edge of the hole, so that the precision is ensured and the pollution is prevented; when the step chamfer is arranged at the edge of the ruler body, the step chamfer is of a step structure, and particularly refer to fig. 3; when the step chamfer is disposed at the edge of the hole, the hole chamfer 32 is also of a stepped configuration, as shown in fig. 3.
Fig. 2 is a schematic structural view of a conventional hole 31, which is prone to cause deviation during drawing due to its structure, and is prone to cause ink accumulation due to the fact that the pen tip 11 and the hole are not separated when the pen tip 11 stays for a long time, and to contaminate the drawing when the ink is inadvertently touched to the ink position 4.
The instrument chi of taking chamfer structure of this embodiment, edge at ruler body and hole is provided with the chamfer structure, make it form hypotenuse formula edge, the hypotenuse at this edge can set up various different inclination according to the commonly used application scene of this product, the instrument chi at this hypotenuse formula edge has been adopted, when accomplishing great thickness, the nib of various instrument pens has excellent trafficability characteristic, also show the precision that has improved the drawing, if adopt ink pen drawing figure, the instrument chi upset that has the hypotenuse formula edge of this application uses, ink pen's nib position breaks away from completely with the ruler, the drawback of the drawing of making dirty easily when having solved ink pen drawing figure.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
