Specific embodiment

The utility model is described in detail below in conjunction with the embodiment that accompanying drawing is given.

Embodiment 1：

Referring to accompanying drawing 1 to accompanying drawing 2, in figure：Ratio plate body 1, ledgement 2, ordinate bar 3, pinhole arrangement 4, supporting plate 5.

A kind of sketch ratio plate, referring to accompanying drawing 1 to accompanying drawing 2, the transparent structure of ratio plate body 1, by PVC materials or its He is made transparent material, is provided with or square grids structures on ratio plate body 1, size of mesh opening 0.5cm × 0.5cm；Constitute Pinhole arrangement 4 is respectively arranged with the horizontal stroke of square net, the crosspoint of ordinate bar 2,3；So, can be with, using another with The completely equivalent ratio plate body of the dimensions of ratio plate body 1, in the case of perfectly aligned grid ordinate bar, by pin hole By the aperture that the positioning method in fine needle bundle hole is equal by spacing is all covered with entire paper in structure 4, produced when easily facilitating sketch Raw precise positioning.

Or only on the horizontal, crosspoint of ordinate bar in the network on ratio edges of boards edge pin hole is provided with, to reduce To the destructiveness of photo.Network is covered with ratio plate body 1, and the surrounding of ratio plate body 1 is horizontal with the edge of grid lines, ordinate Bar 2,3 coincides；The back side of ratio plate body 1 is provided with supporting plate 5.

The present embodiment in use, carrying photo between the back side of ratio plate body 1 and the front of supporting plate 5, with hardboard As supporting plate 5, pin or other small fine needles are plugged in pinhole arrangement 4, fixed, prevented play phenomenon and produce Ratio changes and influences the generation of delineation problem.

Photo is divided into several small squares by ratio plate body 1 by square net, and then sketch person is according to small net Lattice carry out equal proportion scaling to photo, reach and are accurately positioned, the effect of accurate scaling.

Embodiment 2：

Referring to accompanying drawing 3 to 5, in figure：Ratio plate body 1, ledgement 2, ordinate bar 3, geometrical clamp 401, groove 501, supporting plate 5th, magnetic body structure 7, magnet 8.

In the present embodiment, the transparent structure of ratio plate body 1 is made up, ratio plate sheet of PVC materials or other transparent materials It is provided with body 1 or square grids structures, size of mesh opening 0.5cm × 0.5cm；Or other sizes are set to according to actual needs Fenestral fabric.Network is covered with ratio plate body 1, and the surrounding of ratio plate body 1 is horizontal with the edge of grid lines, ordinate bar 2nd, 3 coincide；The back side of ratio plate body 1 is provided with supporting plate 5.

Groove 501, the width of groove 501 and the office sold on the market are set on two diagonally opposing corners of supporting plate 5 or corner It is adapted with the width of geometrical clamp.The groove 501 is arranged far from the supporting plate 5 of the one side of ratio plate body 1.Filled on groove 501 There is a medial surface of geometrical clamp 401, another medial surface of geometrical clamp 401 and the outer surface of ratio plate body 1 are in contact（Also It is to be clamped supporting plate 5 and ratio plate body 1 by geometrical clamp 401）.Magnetic body structure 7 is provided with supporting plate 5, can be prevented There is the middle uneven phenomenon that arches upward, it is possible to use small magnet 8 etc. is attached to ratio plate when area is excessive in ratio plate body 1 On body 1, so, the relative smoothness of ratio plate body 1 can be increased, beneficial to being smoothed out for sketch.
