Fig. 1 is a first schematic structural diagram of an embodiment of the present invention;

FIG. 2 is a schematic structural diagram of an embodiment of the present invention;

fig. 3 is a sectional view of a fixing clip according to an embodiment of the present invention.

In the figure: 1-drawing board, 2-fixing clip, 21-U-shaped opening, 22-threaded hole, 3-positioning ruler, 4-drawing ruler, 41-drawing seam, 5-fastening screw, 6-pressing disc, 7-rotating handle, 8-buffer layer and 9-hinged shaft.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1: as shown in fig. 1~3, a perspective drawing rule, including drawing board 1, drawing board 1 edge is provided with fixes 2 at the drawing board edge, be provided with positioning ruler 3 on the fixing clip 2, positioning ruler 3 tip articulates there is drawing rule 4, drawing rule 4 middle part is equipped with drawing seam 41 along drawing paper length direction.

In this embodiment, the fixing clip 2 is provided with a U-shaped opening 21, the U-shaped opening is sleeved on the edge of the drawing board, a fastening screw 5 penetrating through the upper part of the fixing clip and extending into the U-shaped opening is arranged above the fixing clip, and a pressing disc 6 is fixedly connected to the lower end of the fastening screw 5.

In this embodiment, the drawing slit may also be a linear strip.

In this embodiment, the upper end of the fastening screw 5 is fixed with a rotating handle 7, and the rotating handle can adjust the position of the positioning ruler and fix the positioning ruler on the drawing board.

In the embodiment, in order to reduce damage to the drawing board and protect the drawing board, the lower surface of the compressing disc is provided with a buffer layer 8; the buffer layer can be a rubber pad or sponge.

In this embodiment, the fixing clip is provided with a threaded hole 22 for passing a fastening screw.

In this embodiment, the end of the positioning ruler is hinged to the end of the drawing ruler via a hinge shaft 9.

In this embodiment, during the use, arrange the disappearance point position of perspective in earlier articulated shaft 9 between drawing rule 4 and the locating ruler 3, arrange the other end of locating ruler 3 in the suitable place in drawing board edge again, clip locating ruler and drawing board edge with the fixation clamp, rotatory rotation handle drives fastening screw 5 and compresses tightly disc 6 and pushes down, makes and compress tightly disc 6 and firmly fix locating ruler 3 at the drawing board edge. Thus, the movable end of the drawing rule can be rotated, and the perspective line is drawn along the drawing slit of the drawing rule.

Example 2: if two sets of perspective drawing rules are used, two vanishing points on the left and right of a horizontal line of sight can be determined, and a perspective line with angular perspective can be conveniently drawn; if three sets of perspective drawing rules as described above are used, three vanishing points can be determined and used to draw a three-point perspective.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

If the terms "first," "second," etc. are used herein to define parts, those skilled in the art will recognize that: the terms "first" and "second" are used merely to distinguish one element from another in a descriptive sense and are not intended to have a special meaning unless otherwise stated.

Also, above-mentioned the utility model discloses if disclose or related to mutually fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
