Abstract

The utility model discloses a tool used for drawing forms and comprises that: length scales (2) are marked on the upper part of the upper surface or the inner side surface of side frames (10) of a rectangle frame (1), and the scales (2) on the two side frames (10) are symmetric; a ruler is arranged on the two side frames (10) in a sliding way to be used as a slide rule (3); the tool can draw forms with neat and beautiful lines conveniently and quickly and can adjust the distance of each grid in the form conveniently.

Description

Draw the instrument of form

Technical field

The utility model relates to a kind of instrument of drawing form.

Background technology

All need to make form in a lot of occasions, be used to make a report on or add up various data; People also need draw the grid that is similar to form, so that write neatly good-lookingly to word when especially the student writes on blank sheet of paper on blank sheet of paper.Draw form with existing ruler, then be easy to line drawing askewly, line and distance between centers of tracks differ, and the form that draws was both irregular, and was also not attractive in appearance, and operation very bothers.

The utility model content

The purpose of this utility model just provides a kind of instrument of drawing form, this instrument lines form neat, attractive in appearance that can draw quickly and easily, and can regulate the spacing between each grid in the form easily.

The utility model solves its technical problem, and the technical scheme that is adopted is: a kind of instrument of drawing form, and its structure is: the upper surface of the side frame of rectangle frame or the top of inner surface, mark lengths scale, the scale symmetry on the frame of both sides; A ruler is slidably mounted on the frame of both sides as slide rule.

During use, instrument is set level, side frame is parallel with the dual-side of paper, and slide rule moves up and down desired location along the chute of side frame, pushes down slide rule, with straight line on the stroke; Draw runner is moved straight next desired location, the second straight line that can draw is so that any many horizontal flat lined lines again; Just whole ruler revolves and turn 90 degrees use, the perpendicular ruling of the plurality of vertical of then can drawing; The various forms thereby the utility model can draw.

Compared with prior art, the beneficial effects of the utility model are: because slide rule can be mobile in chute easily, and can not obliquely be offset, many parallel form lines soon therefore can draw; Spacing between line and the line can be regulated definite by the scale on the left and right side frame easily, thus the horizontal and/or perpendicular form line of any spacing of can drawing as required.In a word, with ruler of the present utility model can draw quickly and easily spacing evenly, the various forms of neat appearance.

The concrete structure that above-mentioned slide rule is slidably mounted on the frame of both sides is: the inboard of both sides frame has the chute adaptive with the slide rule end, and the two ends of slide rule embed in the chute.

Above-mentioned slide rule end is " L " shape of evagination, horn-like, spherical crown shape.

Above-mentioned slide rule be slidably mounted on the frame of both sides concrete structure can also for: the end of slide rule is to lower convexity, and frame top, both sides has the chute adaptive with the convex shape of slide rule end, and the projection of slide rule end is embedded in the chute.

More than the adapted shape of these be slidingly connected mode and junctions, simple structure, easy to manufacture, slide flexibly, easy to use.

The side frame of above-mentioned rectangle frame is telescopic frame, and this telescopic frame is that two joint frame fits constitute.

The side frame of above-mentioned rectangle frame can also frame be hinged constitutes by two joints.

Adopt flexible fit or hinged overturn structure, side frame length of the present utility model is reduced, area occupied is little, is convenient for carrying, deposits.When especially the student uses, ruler directly can be positioned in the writing case, carry more convenient.

Adopt articulated structure, slide rule can also be extracted out from the junction of two joint side frames, uses as independent ruler.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

The specific embodiment

Embodiment one

Fig. 1,2 illustrates, a kind of specific embodiment of the present utility model is: a kind of instrument of drawing form, the upper surface of the side frame 10 of rectangle frame 1 or the top of inner surface, mark lengths scale 2, scale 2 symmetries on the both sides frame 10, the initial upright position that is both sides frame scale is identical, and the unit spacing is identical.A ruler is slidably mounted on the both sides frame 10 as slide rule 3.

The concrete structure that slide rule 3 is slidably mounted on the both sides frame 10 is: the inboard of both sides frame 10 has the chute 4 adaptive with slide rule 3 ends, and the two ends of slide rule 3 embed in the chute 4.

The side frame 10 of rectangle frame 1 is hinged and connected by hinge 8 by two joint frames and constitutes.

Embodiment two

Fig. 3 illustrates, and present embodiment and embodiment one are basic identical, and different only is: slide rule 3 ends are " L " shape of evagination.

Embodiment three

Fig. 4 illustrates, and this example is basic identical with embodiment one, and different only is: slide rule 3 ends are the horn-like of evagination.

Embodiment four

Fig. 5 illustrates, and this example is basic identical with embodiment one, and different only is: the end of slide rule 3 is to lower convexity 3a, and frame 10 tops in both sides have the chute 4 adaptive with the protruding 3a shape of slide rule 3 ends, and the protruding 3a of slide rule 3 ends is embedded in the chute 4.It is downward horn-like that the protruding 3a of this example is.

Embodiment five
