Abstract
The utility model relates to a ruler, which comprises a ruler body, wherein one edge of the ruler body is provided with a sliding strip which is extended along the edge of the ruler body where the sliding strip is arranged; and the back side of the sliding strip is provided with a vertical chute. When the ruler is used, a drawing board which is matched with the ruler for use comprises a ruler sheet and a board body, wherein a rib is arranged on the ruler sheet and taken as a slideway and the chute of the ruler body is inserted on the rib, thereby the ruler can be positioned and then is not required to be forcibly pressed by a hand, consequently the drawing operation is simple and convenient.
Description
(1) technical field
The utility model relates to a kind of chi.
(2) background technology
Existing chi all is a tabular, and use the ruler of this structure to have many inconvenient parts on drawing board: ruler is difficult to the location, is easy to generate deflection in drawing course.In order to make ruler in drawing course, obtain the location, must use a hand firmly to pin ruler, operate very inconvenient.
(3) summary of the invention
In order to overcome the deficiency of existing ruler inconvenient operation, the utility model provides a kind of easy to operate ruler.
The technical scheme in the invention for solving the technical problem is: a kind of chi, comprise the chi body, and a limit of described chi body also is provided with draw runner, and this draw runner extends along the limit of the chi body at its place, and the back side of described draw runner offers chute longitudinally.
In general, this chi is a drawing square, and described draw runner is positioned on the right-angle side of described drawing square, can certainly be positioned on the hypotenuse of described drawing square.
In general, described drawing square is the isosceles drawing square, and perhaps two of described drawing square acute angles are 60 ° and 30 °.
Described chute has one or two.
The utility model in use, drawing board matching used with it includes chi sheet and plate body, the chi sheet is provided with rib, this rib is as slide rail, and the chute of chi body is inserted on the rib, thereby can be with this chi location, thereby needn't re-use a hand and firmly pin this chi, easy and simple to handle during drawing.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is that the A-A of Fig. 1 of another kind of structure is to cutaway view.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of chi comprises chi body 1, this chi body 1 is the isosceles drawing square, also be provided with draw runner 2 on the right-angle side of this isosceles drawing square, this draw runner 2 extends along the limit of the chi body at its place, and the back side of draw runner 2 offers a chute 3 longitudinally.Certainly also can be as shown in Figure 3, chute 3 also can be two, or more.
In use, drawing board matching used with it includes chi sheet and plate body, and the chi sheet is provided with rib, this rib is as slide rail, and the chute 3 of chi body is inserted on the rib, thereby can be with this chi location, thereby needn't re-use a hand and firmly pin this chi, easy and simple to handle during drawing.
Certainly draw runner is not limited to be located on the right-angle side, also can be located on the hypotenuse; The chi body also is not limited to the isosceles drawing square, can also be that common acute angle is drawing square or other set square of 60 ° and 30 °.
