Abstract
The utility model discloses a four-line three-grid ruler with scale and belongs to the manufacturing technical field of learning tools. The utility model consists of a oblong ruler, the upper and lower edges of which are provided with scales, wherein, the ruler is provided with two oblong holes which are parallel with the upper and the lower edges of the ruler, and a separation strip between the oblong holes is provided with a scale line which is corresponding with the scales of the upper and lower edges of the ruler. The widths of the middle separation strip of the ruler and the upper and lower oblong holes are same. The widths of the two oblong holes and the middle separation strip of the ruler of the utility model are same as the width of national regulated four-line three-grid. The four-line three-grid ruler can be used for drawing four-line three-grid line as well as drawing grid line shaped like a Chinese character Tian, which has the advantages of simple operation, convenient using, standard writing etc.
Description
Technical field
The utility model discloses a kind of four lines, three lattice chis with scale, belongs to learning tool class manufacturing technology field.
Background technology
At school's learning Chinese phonetic just, teacher usually will finish four lines, three lattice on blackboard, the teaching the student and how to write of good every stroke, and should note which rule.But because teacher directly drawn four straight lines with ruler, general little at interval evenly these four lines are also not parallel sometimes, write out also not attractive in appearance, give and just learnt the student that phonetic alphabet write and bring adverse influence.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of four lines, three lattice chis of band scale reasonable in design, easy to use, simple to operate.
The utility model is achieved through the following technical solutions:
The utility model is made up of rectangular ruler, there is scale at the upper and lower edge of ruler, wherein, have two and parallel rectangular hole, the upper and lower limit of ruler on the described ruler, and on the parting bead between above-mentioned two slots, be provided with and the corresponding graduation mark of the scale on the upper and lower limit of ruler.
The width of two slots of parting bead and its upper and lower in the middle of the described ruler is the same.
Two slots of the present utility model are the same with the width of four lines, three lattice of national regulation with the width of the parting bead of ruler centre.During use, can lie in ruler on the blackboard, get final product in the upper and lower both sides setting-out of two slots respectively with chalk.When needing the picture matts sometimes, when drawing two parallel lines because there is scale at the upper and lower edge of ruler, find and above-mentioned two parallel lines between equidistant position make mark, the two other of drawing then vertical line gets final product, and has advantages such as simple to operate, easy to use, specification writing.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1, ruler, 2, parting bead, 3, slot.
The specific embodiment
Embodiment: structure as shown in the figure, there is scale at the upper and lower edge of ruler 1, wherein, have two and parallel rectangular hole, the upper and lower limit of ruler 3 on the described ruler, and on the parting bead 2 between the above-mentioned slot 3, be provided with and the corresponding graduation mark of the scale on the upper and lower limit of ruler.The width of two slots 3 of parting bead 2 and its upper and lower in the middle of the described ruler is the same, and promptly above-mentioned width is the same big with the width of four lines, three lattice of national regulation.
Claims (2)
1, four lines, the three lattice chis of band scale, form by rectangular ruler, there is scale at the upper and lower edge of ruler, it is characterized in that: have two and parallel rectangular hole, the upper and lower limit of ruler on the described ruler, and on the parting bead between above-mentioned two slots, be provided with and the corresponding graduation mark of the scale on the upper and lower limit of ruler.
2, four lines, the three lattice chis of band scale according to claim 1 is characterized in that: the width of two slots of parting bead and its upper and lower in the middle of the described ruler is the same.
