Abstract

A Russian oblique line drawing ruler. At present, a plurality of right inclined lines which are equidistant and inclined to the right are drawn on a blackboard by a straight ruler in Russian teaching. A Russian slash line drawing ruler comprises: oblique line drawing board (1), go up scale (2) and lower scale (3), it passes through oblique line drawing board to go up scale and lower scale and connects, it is parallel structure to go up between scale and the lower scale, the equidistance is installed plug-in components A (4) that a set of structure is the same on the chi face of going up the scale, the centre of a circle of a set of plug-in components A is on same horizontal straight line, the equidistance is installed plug-in components B (5) that a set of structure is the same on the chi face of lower scale, the centre of a circle of a set of plug-in components B is on same horizontal straight line, a set of plug-in components A is the same with a set of plug-in components B's structure, and a. The utility model discloses be applied to the russian teaching.

Description

Russian oblique line drawing ruler

The technical field is as follows:

the utility model relates to a russian slash setting-out chi.

Background art:

in the russian teaching, the blackboard writing can not be opened, and in order to standardize the writing of the russian letters and let the students can be visual russian letters, a plurality of inclined lines inclined to the right with equal distances are drawn on the blackboard by using a ruler in the russian teaching, and in order to facilitate the writing, the part of the russian writing book is provided with inclined standard lines. At present, in order to enable drawn oblique lines to be equidistant on a blackboard, a teacher needs to mark points by using a measuring ruler when drawing the oblique lines, and then the two mark points are connected by using a ruler.

The invention content is as follows:

the utility model aims at providing a russian slash setting-out chi.

The above purpose is realized by the following technical scheme:

a Russian slash line drawing ruler comprises: the utility model provides a novel plug-in components B's structure is the same, a set of plug-in components B's centre of a circle on the level straight line, plug-in components A and a set of plug-in components B's structure is the same, and a set of plug-in components A and a set of plug-in components B's vertical line be not on the same straight line.

Russian slash setting-out rule, the both ends of slash drawing board seted up opening and lower opening, last opening insert plug-in components A in, work as last opening insert in the first plug-in components A of last scale, and the opening inserts in the first plug-in components B of scale down.

The Russian slash line drawing ruler is characterized in that an inserting column with a T-shaped structure in cross section is installed at the end of the upper ruler, a pull rope is sleeved on the inserting column, and a pendant is connected to the bottom of the pull rope.

The Russian slash line drawing ruler is characterized in that the upper ruler is the same as the lower ruler in length, a magnetic adhesive tape is arranged on the back of the upper ruler and the back of the lower ruler, and the magnetic adhesive tape and the magnetic blackboard are adsorbed.

The utility model has the advantages that:

1. when the utility model is used, the upper scale is firstly absorbed on the magnetic blackboard through the magnetic adhesive tape on the back surface, when the upper scale is parallel to the ground, the pull rope on the upper scale pulls the pull rope through the pendant below the pull rope, so that the pull rope is vertical to the ground, then the left side of the lower scale is attached to the pull rope of the drop, at the moment, the upper scale and the lower scale are in a parallel structure, then an upper opening on the diagonal sliding board is inserted into a first plug-in component A on the upper scale, a lower opening on the diagonal sliding board is inserted into a first plug-in component B on the lower scale, and the diagonal sliding board is in an inclined state, and drawing an oblique line along one side of the oblique line drawing board by using chalk, then lifting the oblique line drawing board upwards, taking the oblique line drawing board out of the plug-in units A and B, and inserting the oblique line drawing board into the second plug-in units A and B to finish the line drawing process of the oblique line.

The utility model has the characteristics of simple structure, convenient operation, portable etc, when the teacher when carrying out russian teaching, can be on the blackboard quick draw the slash, guarantee that the distance between every adjacent slash equals for write more neatly convenient, improved the standard that russian was written, reduce the setting-out time, improved teaching efficiency.

The specific implementation mode is as follows:

example 1:

a Russian slash line drawing ruler comprises: slash drawing board 1, last scale 2 and subscript chi 3, last scale with the subscript chi pass through the slash drawing board connect, last scale with the subscript chi between be parallel structure, the chi face of last scale on the equidistance install the plug-in A4 that a set of structure is the same, a set of plug-in A's centre of a circle on same horizontal straight line, the chi face of lower scale on the equidistance install the same plug-in B5 of a set of structure, a set of plug-in B's centre of a circle on same horizontal straight line, a set of plug-in A and a set of plug-in B's structure the same, and a set of plug-in A and a set of plug-in B's vertical line not on same straight line.

Example 2:

according to the Russian slash drawing ruler in the embodiment 1, an upper notch 6 and a lower notch 7 are formed in two ends of the slash drawing board, the upper notch is inserted into the plug-in A, when the upper notch is inserted into the first plug-in A of the upper ruler, and the lower notch is inserted into the first plug-in B of the lower ruler.

Example 3:

according to the Russian oblique line drawing ruler in the

embodiment

1 or 2, the end part of the upper ruler is provided with an inserting column 8 with a T-shaped cross section, a pull rope 9 is sleeved on the inserting column, and the bottom of the pull rope is connected with a pendant 10.
