Abstract

The utility model relates to a drawing ruler for plotting drawings, such as engineering drawings, etc. The utility model is characterized in that one end of a zero graduation of a straight ruler of which the sectional plane is in an H shape is provided with a hole for fixing a pencil core, and one end of the zero graduation of the straight ruler is also provided with an auxiliary ruler which is fixedly connected to the straight ruler and can be slid along the straight ruler; the auxiliary ruler and the straight ruler form a right angle. The upper part of the auxiliary ruler is provided with a long ruler, and the lower part of the long ruler is fixedly connected with inverse C-shaped sliding blocks. The sliding blocks are sheathed and inserted in long grooves arranged at both sides of the H-shaped straight ruler, and a screw hole and a screw are arranged on each sliding block. The lower side of the sliding block is provided with a center of a circle feet needle which is matched with a pencil core fixed in the hole of the straight ruler for fixing a pencil hole for drawing circles. The auxiliary ruler can be moved on the straight rule according to the drawing requirement by the utility model, and any group of parallel lines can be drawn. The length of the parallel lines and the distance between the parallel lines can be directly read. Besides, the required circle with any radius can be drawn and read by the center of the circle feet needle and the pencil core, which are fixed on the auxiliary ruler and the straight ruler. The problem that two legs of compasses are separated when the two-leg compasses are used for drawing is avoided, thus the accuracy of drawing can be ensured, and the drawing work is convenient.

Description

Drawing rule

Technical field

The utility model belongs to drawing appliance, particularly relates to a kind of drawing rule that various figure such as engineering drawing use of drawing.

Background technology

All only possesses a kind of function at instruments such as present known drawing instrument such as set square, compasses, rulers.When drawing one group of parallel lines, often need to use two set squares combinations to paint; Can not from compasses, directly read drawn radius of a circle numerical value in order to draw the compasses major part of a bowlder in using at present, and often owing to draw the bowlder excessive compasses bipod of exerting oneself a little and open easily and do not draw well circle or the circle that draws is produced than mistake.In addition, often to prepare multiple drawing instruments such as set square, compasses, ruler, bring many inconvenience for drawing work in order to make a figure.

The utility model content

The utility model provides a kind of multiple function that has for solving the technical problem that exists in the known technology, can replace the convenient drawing rule that uses of several drawing instruments when drawing work.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes a ruler, particularly the section of described ruler is an I shape, the one fixing hole of pencil-lead is arranged in zero graduation one end of this ruler, also include one be connected on the described ruler can along described ruler slide and with the meet at right angles secondary chi of assembly relation of described ruler, described secondary chi is that top is long chi, the bottom of long chi is fixed with anti-C shape slide block, secondary chi lower slider cover inserts in the elongated slot of I shape ruler both sides, the fixedly screw hole and the screw of ruler and secondary chi relative position are arranged on slide block, and the downside of slide block have can with described ruler fixedly in the hole of pencil-lead fixing pencil-lead cooperates picture to justify the center of circle pin pin of usefulness.

The utility model can also adopt following technical measures:

Have with the long parallel prolongation in limit of ruler and be connected in vertical adjustment plate on the secondary chi in the be connected part of assembling of secondary chi and ruler.

Be fixed with one in the upper end of secondary chi and be used for the round handle of picture.

Advantage and the good effect that the utlity model has are: add the secondary chi that has with the ruler relation of meeting at right angles owing to adopted in the technical program on ruler, and pencil-lead and center of circle pin pin fixedly are housed in the zero graduation one end lower end and a secondary chi side corresponding of ruler with it, so it can allow secondary chi move can to draw group parallel lines arbitrarily according to the drawing needs on ruler, and the length of parallel lines, the distance between parallel lines all can directly be read on the scale by secondary chi and ruler.In addition; application is fixed on the center of circle pin pin on secondary chi and the ruler and pencil-lead can draw and can directly read the circle of required any radius; and avoided with the bipod compasses disadvantage that the compasses bipod can separate when drawing, thereby guaranteed the accuracy of drawing and greatly facilitate drawing work.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A profile of ruler among Fig. 1

Fig. 3 is the structural representation of the secondary chi of Fig. 1

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

As shown in Figure 1, 2, ruler 1 is that a section is that I shape is the chi that both sides have elongated slot 9.Tight fit is inserted pencil-lead 5 in the pencil-lead hole of the zero mark end one side elongated slot 9 of ruler 1.Secondary as shown in Figure 3 chi 2 to be a top be long chi, the bottom of long chi is conjuncted is equipped with anti-C shape slide block 3, at the bottom fixed bonding of anti-C shape slide block 3 center of circle pin pin 6 is arranged.In the elongated slot 9 of ruler 1 blade both sides, can cooperate embedding to be inserted on the ruler 1 by ruler 1 left-hand end two corresponding protruding plate 10 parts on secondary chi 2 lower slider 3 as shown in Figure 1, 2, 3.One extended to the right vertical adjustment plate 4 is arranged on the right side of slide block 3 in addition, on slide block 3 and vertical adjustment plate 4, also be useful on secondary chi 2 is fixed in screw hole and screw 7 on the ruler 1.In addition, round handle 8 also fixedly is equipped with on the top on secondary chi 2 as shown in Figure 1, to use with the bowlder of drawing a picture.

The slide block 3 of during use because secondary chi 2 bottoms is to be enclosed within on ruler 1 blade, secondary chi 2 can horizontally slip on ruler 1, when aliging with the top of chi face on the top of the extended vertical adjustment plate 4 of slide block 3 and the ruler 1, tighten ruler 1 and secondary chi 2 fixed to one another with two hand screws 7 more to the right with after guaranteeing that secondary chi 2 and ruler 1 are orthogonal.In the time will drawing one group of parallel lines, ruler 1 motionless secondary chi 2 moves on ruler 1 like this, regulate these group parallel lines that vertical adjustment plate 4 just can draw required simultaneously, and the length and the distance between parallel lines of these group parallel lines can be read from secondary chi 2 and ruler 1 respectively.When needs picture bowlder, regulate the distance of 5 of zero graduation place pencil-leads on secondary chi 2 center of circle pin pins 6 and the ruler 1 and can read radius from ruler 1, after this tighten can draw circular arc or circle of round handle 8 that screw 7 rotates secondary chi 2 upper ends by hand and come.In addition as shown in Figure 1, indicate line by the angle on the secondary chi 2 and also can measure arbitrarily angle less than 120 °.
