Abstract
The utility model relates to a mathematics teaching aid, especially to a ruler specific for drawing parallel lines The ruler specific for drawing parallel lines comprises a vertical rack and a ruler and is characterized in that a chute is vertically arranged on the surface of the vertical rack, one end of the ruler is slidingly connected with the chute, the ruler is perpendicular to the vertical rack, the side surface of the vertical rack is graduated, and a line-drawing groove is arranged on the surface of the ruler. Therefore, the ruler specific for drawing parallel lines is simply structured, practical and convenient.
Description
(1) technical field
The utility model relates to a kind of mathematical education apparatus, particularly a kind of parallel setting-out special ruler.
(2) background technology
On the present mathematical education class; Needing teacher on the blackboard of being everlasting, to draw parallel lines, generally is with two set squares, and sliding on another set square through a set square is depicted as; Operation is more loaded down with trivial details like this; And the process intermediate cam chi of setting-out slides easily, also can't confirm the distance of two parallel lines, so just reduced the efficient of teaching.
(3) summary of the invention
The utility model provides a kind of simple in structure, practical and convenient parallel setting-out special ruler in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of parallel setting-out special ruler comprises perpendicular frame and ruler, and it is characterized in that: said perpendicular frame surface longitudinal is provided with chute, and an end and the chute of ruler are slidingly connected, and ruler is vertical with perpendicular frame; Said perpendicular frame surface sidepiece is provided with scale; Said ruler surface is provided with the setting-out groove.
Said perpendicular frame lower surface is provided with anti-skidding line.
The beneficial effect of the utility model is: the parallel setting-out special ruler of this utility model is simple in structure, and is simple to operate in the time of use, also can not move in the process of setting-out, effectively raises the efficient of teaching, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model;
Among the figure, 1 perpendicular frame, 2 rulers, 3 chutes, 4 scales, 5 setting-out grooves, 6 anti-skidding lines.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises perpendicular frame 1 and ruler 2, and it is characterized in that: said perpendicular frame 1 surface longitudinal is provided with chute 3, and an end and the chute 3 of ruler 2 are slidingly connected, and ruler 2 is vertical with perpendicular frame 1; Said perpendicular frame 1 surperficial sidepiece is provided with scale 4; Said ruler 2 surfaces are provided with setting-out groove 5; Said perpendicular frame 1 lower surface is provided with anti-skidding line 6.
Adopt the parallel setting-out special ruler of the utility model, in the time of use, with erecting a certain position that is placed on blackboard that frame 1 is fixed; Setting-out in the setting-out groove 5 of ruler 2 is then moved ruler 2 and is made it parallel in chute 3, just can skid off parallel lines; Practical and convenient, quick.
Claims (2)
1. a parallel setting-out special ruler comprises perpendicular frame (1) and ruler (2), it is characterized in that: said perpendicular frame (1) surface longitudinal is provided with chute (3), and an end of ruler (2) and chute (3) are slidingly connected, and ruler (2) is vertical with perpendicular frame (1); The surperficial sidepiece of said perpendicular frame (1) is provided with scale (4); Said ruler (2) surface is provided with setting-out groove (5).
2. parallel setting-out special ruler according to claim 1 is characterized in that: said perpendicular frame (1) lower surface is provided with anti-skidding line (6).
