Abstract

The utility model provides a series of new-type drawing rulers. A ruler body is provided with a long hole whose bottom is provided with equidistant grids. The utility model can rapidly draw dotted lines, and does not need to lift pens when draws dotted lines as before. Solid lines can be drawn by an outer edge of the ruler. Thus, the utility model can improve efficiency of drawing work.

Description

Drawing rule

The utility model relates to a series of novel drawing chis.

Draw with existing conventional and will start writing every now and then when drawing dotted line with a pair of mutually perpendicular ruler in length and breadth on chi such as ruler, T-square, set square, the draught machine, not only slow but also tire out and the dotted line drawn neat inadequately.

The purpose of this utility model is that a series of novel drawing chi will be provided, and utilizes them can draw the dotted line of high-quality apace like a cork, also can paint solid line.

The purpose of this utility model is achieved in that offers one or several elongated holes on the chi body, thin uniformly at interval grid are set along the bottom of elongated hole.When drawing dotted line, nib moves along the edge of elongated hole, produces contacting of interruption uniformly through stopping with chi drawing down of grid.The person's handwriting that stays on the drawing between two grid just forms dotted line, does not need to start writing every now and then.Solid line is still drawn with the outer edge of chi.

Fig. 1, Fig. 3, Fig. 4 and Fig. 5 are respectively wherein three embodiment of the present utility model.Their configuration design is adopted existing conventional to draw respectively and is used chi: ruler, T-square, the common shape of set square.

Above-mentioned each figure all represents with Fig. 2 along the cutaway view of A-A line.

See figures.1.and.2: (1) is the chi body that lucite or other transparent materials are made, and has elongated hole (2) on it.(3) be thin uniformly at interval grid, the method that they and elongated hole (2) are reinstated injection moulding is made, perhaps the method that is fixed on the bottom of elongated hole (2) again with intensity transparent sheet of material punching is preferably made, and thickness is that 0.10-1.4mm can make nib successfully streak.When an edge along elongated hole (2) streaks, just can on the paper under the chi, mark dotted line like this.

About the explanation of the explanation of all the other each figure and Fig. 1, Fig. 2 identical.

Configuration design of the present utility model can also adopt other existing conventional to draw with a pair of mutually perpendicular ruler in length and breadth on chis, the drafting machine, and satisfying different needs, and the method for being convenient to utilize existing manufacturing technique, equipment to be transformed is implemented.

Claims (2)

1, novel drawing chi, their configuration design is adopted existing conventional to draw respectively and used chi: ruler or T-square or set square or other existing conventional are drawn and are used chi, or the common shape of a pair of mutually perpendicular ruler in length and breadth on the draught machine has the chi body of being made by lucite or other transparent materials (1), it is characterized in that: one or more elongated holes (2) are arranged on the chi body (1), thin uniformly at interval grid (3) are arranged along the bottom of elongated hole (2).

2, by the novel drawing chi of claim 1 regulation, it is characterized in that: the uniform at interval thickness of thin grid (3) is 0.10～1.4mm.
