Abstract

The utility model relates to a multipurpose ruler for drawing a table quickly and measuring an angle. The multipurpose ruler is a ruler having an inner ruler 2. The utility model is characterized in that two longitudinal short rulers 3 which are symmetrical right and left are arranged on a straight ruler 1 arranged at the upper part of the inner ruler 2. Both ends of the ruler 1 are provided with two protractors 4. The graduation line of the longitudinal short ruler 3 can be used for shift count when the marking is conducted, and the parallelism of the marking can be ensured by the coincidence of the graduation line and the marking. Thus the quality is greatly enhanced, and the speed is quickened. The ruler can conduct the angle measurement by the protractor arranged on the ruler. The utility model has the advantages of multipurpose, simple structure, novelty, beautiful appearance and low cost.

Description

Multipurpose ruler for drawing table quickly and measuring angle

The utility model is the fast Multipurpose ruler of energy angle measurement degree of a kind of stroke of form, belongs to school supply and stationery.

Ruler commonly used has general ruler, and the chi ruler is two kinds in the band, and the ruler of chi is when drawing form in the band, and its speed can improve 50% than general ruler, but operation is still more loaded down with trivial details, and speed is still fast inadequately, and the levelness of line is difficult for guaranteeing that quality is undesirable.

The purpose of this utility model is to design that a kind of can to draw form convenient especially, the multipurpose ruler of faster, better quality of speed and energy measurement angle again so that a chi many with and improve work efficiency.

The ruler of chi in the purpose of this utility model is achieved in that and has one, within it on the ruler on chi top, be provided with two vertically short scales of left and right symmetry, guarantee the depth of parallelism of ruling with the scale line of this scale and overlapping of line, and easily and directly move distance with this scale itself and count, thereby realize disposable operation line, fundamentally to remove the troublesome operation of moving apart from drawing line between point, point, whole tabulation operational sequence is simplified greatly, work efficiency improves greatly, and the depth of parallelism is good between line, the quality height.In addition, this chi also is provided with two 90 ° of protractors at the left and right two ends of ruler, makes this chi also have the effect of protractor, is a multi-functional ruler.

Further narrate with drawings and Examples below.

Description of drawings:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the vertically situation enlarged drawing of short scale of Fig. 1.

By Fig. 1,2 as seen, a kind of stroke of form of the utility model fast can the angle measurement degree Multipurpose ruler be one have in the ruler 1 of scale 2, it is characterized in that on the ruler 1 on interior scale 2 tops be provided with two vertically short scales 3 of left and right symmetry, the two ends of ruler 1 are provided with two protractors 4.

As seen from Figure 2, in the present embodiment, the graduation mark of vertically short scale 3 is longer, like this when drawing form, with this scale line and overlapping of having rule, operate not only make things convenient for but also can guarantee to rule between the depth of parallelism, can improve work efficiency and quality.

When this ruler is drawn style in use, earlier by 2 standardized baselines of interior chi, aim at baseline by the scale line of vertical short scale then and move distance, again by interior chi 2 places setting-out, so just can obtain one group of horizontal line,, chi (or paper) be changeed 90 ° with same operation, operation just can get one group of ordinate like this again, and so far form is promptly finished.This shows that operation is very convenient, and the step preface such as need not find range, put a little again that so work efficiency is high and vertical overlapping of scale line and setting-out, make the depth of parallelism between its line good, the form quality is good; And the angle measurement function of left and right looking somebody up and down hornwork, it is multi-functional that this chi is had.

By Fig. 1,2 as seen, the convenience that this Multipurpose ruler consider to use is starting point with the scale mark of interior chi with the right, and like this when drawing table, just the line that at every turn draws of assurance is isometric easily with interior chi.

In sum, this Multipurpose ruler can have following advantages:

1. a chi is multiplex, both has been used as ruler, can be used as protractor again;

2. draw form work efficiency height, easy and simple to handle, the lines depth of parallelism is good, the quality height;

3. simple in structure, novel and beautiful, good and cheap.

Claims (2)

1, the Multipurpose ruler that a kind of stroke of form fast can the angle measurement degree is one to have the ruler (1) of interior scale (2), it is characterized in that being provided with on the ruler (1) on interior scale (2) top two vertically short scales (3) of left and right symmetry, the two ends of ruler (1) are provided with two protractors (4).

2,, it is characterized in that described interior scale (2) is that a graduated scale is that from a left side the interior scale of starting point, described protractor (4) are 90 ° of protractors by the Multipurpose ruler of the quick energy of the described a kind of stroke of form of claim 1 angle measurement degree.
