Abstract
The utility model relates to a ruler which comprises a ruler body with a first mark, wherein the ruler body is provided with a rectangular through hole; a pair of opposite sides of the rectangular through hole are parallel to the long sides of the ruler body; the ruler body is provided with a second mark at the other pair of opposite sides of the rectangular through hole; and the first mark and the second mark are mutually vertical in the arrangement direction. The ruler precisely confirms the position of parallel lines of the preset distances by using the rectangular through hole, the first mark and the second mark which are mutually vertical; the rectangular through hole is convenient for determining the position of drawing lines; and straight lines which are mutually parallel or vertical on a position of the ruler can be drawn out by the ruler, thus being convenient for drawing the parallel lines and tables.
Description
Technical field
The utility model relates to a kind of stationery, relates in particular to a kind of ruler.
Background technology
Existing ruler is generally a rectangular plastic plate with scale, and scale is arranged on the length direction of rectangular plastic plate usually.This ruler generally is to draw parallel lines earlier when drawing parallel lines, and draws another parallel lines then behind the shift position again.The parallel lines that draw like this are all parallel inadequately usually, decide because the position of second parallel lines is only judged by setting-out person's range estimation.This ruler is inconvenient especially when drawing form, because form constitutes by first group of parallel lines and perpendicular to second group of parallel lines of these first group of parallel lines usually, the bad assurance of verticality of the depth of parallelism of parallel lines and different group of parallel lines on the same group, also bad operation during drafting.And the corner angle of rectangular plastic plate hurt the user easily.
Summary of the invention
Fundamental purpose of the present utility model is to propose a kind ofly to be convenient to draw parallel lines and the ruler of form.
For realizing above-mentioned fundamental purpose, the technical solution adopted in the utility model is: a kind of ruler, comprise chi body with first scale, the chi body has rectangular through-hole, the a pair of relative edge of rectangular through-hole is parallel to the long limit of chi body, the chi body has second scale at another of rectangular through-hole to relative edge's one side, and first scale is vertical mutually on arranged direction with second scale.
The utility model utilizes rectangular through-hole and orthogonal first scale and second scale accurately to determine the parallel lines position of preset distance, rectangular through-hole has made things convenient for determining of Plotted line position, and can draw in a position of ruler is parallel to each other or orthogonal straight line, has made things convenient for the drafting of parallel lines and form.
Description of drawings
Fig. 1 is the structural representation of the utility model ruler.
Below in conjunction with accompanying drawing utility model is described in detail.
Embodiment
Referring to Fig. 1, ruler of the present utility model comprises chi body 1 and at the protractor 2 and 3 at chi body 1 two ends, chi body 1 and protractor 2, the 3 preferred transparent plastics that adopt are one-body molded.The utility model has been eliminated the corner angle that may injure the user, but and use amount hornwork 2,3 takes measurement of an angle, radian or draw angle, camber line.
Chi body 1 is the rectangular flat shape, has first scale 11 and the rectangular through-hole in the middle 12 that are provided with along its long limit.The a pair of long limit of rectangular through-hole 12 is parallel to the long limit of chi body 1.It is vertical mutually on arranged direction with second scale 13 that chi body 1 has second scale, 13, the first scales 11 in pair of short edges one side of rectangular through-hole 12.When drawing parallel lines, can utilize second scale 13 accurately to determine the distance of many parallel lines; When drawing form, can use first scale mark 11 and second scale mark 13 accurately to determine the position of horizontal, the parallel longitudinal line of form simultaneously.Rectangular through-hole 12 has made things convenient for determining of Plotted line position, and can draw in a position of ruler and be parallel to each other or orthogonal straight line, has made things convenient for the drafting of parallel lines and form.Preferably, the width h of rectangular through-hole 12 is half of chi body 1 width H, like this, can be very easy to the drafting of parallel lines and form at the disposable parallel lines of four standards that draw in a position of ruler.
Claims (4)
1. ruler, comprise chi body with first scale, it is characterized in that, described chi body has rectangular through-hole, the a pair of relative edge of described rectangular through-hole is parallel to the long limit of described chi body, described chi body has second scale at another of described rectangular through-hole to relative edge's one side, and described first scale is vertical mutually on arranged direction with described second scale.
2. ruler according to claim 1 is characterized in that, described ruler also is included in the protractor of described chi body one end.
3. ruler according to claim 2 is characterized in that, described ruler also is included in another protractor of the described chi body other end.
