Abstract

The utility model relates to a novel engineering drawing ruler, which comprises a T-square and a right-angle triangular ruler, wherein a sliding rail is arranged on a graduated scale of the T-square, a sliding block is arranged at the right-angle tip of the right-angle triangular ruler, and the sliding block is arranged in the sliding rail of the T-square. According to the novel engineering drawing ruler, the T-square and the right-angle triangular ruler are combined, the triangular rubber can slide on the T-square and can be used for rapidly and accurately drawing various lines, thereby helping a user to rapidly and accurately draw an engineering drawing and greatly improving the drawing efficiency; and the novel engineering drawing ruler disclosed by the utility model has the advantages of simple structure and strong practicability.

Description

New type of engineering drawing ruler

Technical field

The utility model relates to a kind of drawing apparatus, especially a kind of new type of engineering drawing ruler.

Background technology

Ruler is a necessary tool in Graphing of Engineering, and especially various rulers are like T-square, set square etc.T-square is claimed T shape chi again, is " fourth " font ruler that an end has strut rail, is made up of mutually perpendicular chi head and blade, generally adopts transparent organic glass to make, and cooperates drawing board to use when drawing drawing in the engineering design of being everlasting.

Drawing a width of cloth drawing often need use many ruler.T-square often is the instrument for the mapping of picture horizontal line, when drafting condition straight line, just needs the cooperation set square to be combined into various states and uses, and some decide the straight line of angle in drafting in addition; T-square can't be drawn with cooperating also of set square, often need divide several steps to accomplish, and so frequent combination is more loaded down with trivial details with the substep operation; Lose time; Easy error also, its efficient is low, brings a lot of worries for the drawing personnel.

The utility model content

To the above-mentioned very loaded down with trivial details also deficiency of easy error of ruler that in drawing, is used; The purpose of the utility model provides a kind of new type of engineering drawing ruler; It combines T-square and set square, and set square can slide on T-square, can quick and accurate help people to draw.

For the technical scheme that purpose adopted that realizes the utility model is: a kind of new type of engineering drawing ruler is characterized in that: it is made up of T-square and straight set square; The rule of described T-square is provided with slide rail; Most advanced and sophisticated place, the right angle of described straight set square is provided with slide block, and the inboard of slide block is located in the slide rail on the T-square, and the outside is outside slide rail.

The beneficial effect of the utility model is: it combines T-square and set square; Set square can slide on T-square; Can quick and precisely draw various lines, thereby help user's quick and accurate to draw engineering drawing, improve drawing efficiency greatly; It is simple in structure, and is practical.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment being further described to the utility model.

Fig. 1 is the topology view of the utility model.

Fig. 2 is the sectional drawing at A-A place.

Among the figure, 1-T-square, 2-fan groove, the straight set square of 3-, 4-slide block, 5-slide rail.

The specific embodiment

In Fig. 1, first embodiment shown in Figure 2, a kind of new type of engineering drawing ruler is characterized in that: it is made up of T-square and straight set square; The rule of described T-square is provided with slide rail; Most advanced and sophisticated place, the right angle of described straight set square is provided with slide block, and the inboard of slide block is located in the slide rail on the T-square, and the outside is outside slide rail.

In second embodiment shown in Figure 1, described straight set square links to each other through hinge with the outside of slide block, and straight set square can rotate around tie point; Offer fan groove on the right angle of straight set square, the arc edge of fan groove is provided with the scale that takes measurement of an angle.

When using the utility model; Rule with T-square is a datum line; Straight set square can horizontally slip on T-square through slide block; Thereby find corresponding scale accurately, the straight line that draws accurately can also draw through the scale that takes measurement of an angle on the set square and the rotation of straight set square simultaneously and be partial to the straight line of the various angles of datum line.

Claims

1. new type of engineering drawing ruler, it is characterized in that: it is made up of T-square and straight set square; The rule of said T-square is provided with slide rail.

2. new type of engineering drawing ruler according to claim 1 is characterized in that: most advanced and sophisticated place, the right angle of said straight set square is provided with slide block, and the inboard of slide block is located in the slide rail on the T-square.
