Abstract

A multipurpose ruler for drawing lines for teaching comprises a vertical ruler and a horizontal ruler. A chute is formed in the vertical ruler lengthways. The horizontal ruler is connected with the chute of the vertical ruler in a sliding mode through a hinge pin hinged on the horizontal ruler. An arbitrary angle ruler is hinged on the hinge pin. Angle scale marks are arranged on the top face of the hinge pin. The horizontal ruler is perpendicular to the vertical ruler. Scales are arranged on surfaces of the vertical ruler and the horizontal ruler. By the adoption of the vertical ruler, a perpendicular line can be drawn. Due to the fact that the horizontal ruler can move in an up and down mode along the vertical ruler, parallel lines are convenient to draw. Due to the fact that the arbitrary angle ruler is hinged on the hinge pin, and the angle scale marks are arranged on the top face of the hinge pin, oblique lines with arbitrary angles are convenient to draw. The multipurpose ruler for drawing the lines for teaching has the advantages of being simple in structure, practical, convenient to use and accurate in line drawing. The multipurpose ruler for drawing the lines for teaching can be widely used as a teaching line drawing tool for drawing pictures on a blackboard in finance teaching.

Description

Teaching setting-out multipurpose ruler
Technical field:
The utility model relates to a kind of teaching line drawing ruler, the particularly finance teaching line tool that blackboard draws of giving lessons.
Background technology:
The finance teacher will draw various figures at blackboard in the process of teaching of being everlasting at present, need many in picture parallel, vertical line, oblique line, curve etc., there is not special-purpose instrument at present, error is very big, speed is slow, waste time and energy, in order to address this problem, people have done multiple effort, the technology that a key name is called " blackboard angle scriber " is disclosed as Chinese patent CN201020276409.3 number, introduced a kind of blackboard angle scriber, its structure comprises angle scale and line drawing ruler, and the surface of angle scale is provided with angle line, the cross section is that the center of I-shaped angle scale is provided with relatively turnable rotating shaft, one end of the middle part of rotating shaft and line drawing ruler is fixed together, and the top of rotating shaft is connected with an end of U-shaped turning handle, and the other end and the line drawing ruler of U-shaped turning handle are fixed together.This technology can be drawn arbitrarily angled line at blackboard easily, and the deficiency of existence is function singleness, and the teacher needs to prepare multiple chi in the process of teaching could satisfy the teaching needs, and addressing this problem becomes urgent need.
The utility model content:
Overcome the deficiencies in the prior art, design a kind of simple in structurely, easy to operate, can draw the teaching setting-out multipurpose ruler of parallel vertical setting-out and various angle lines easily.Teaching setting-out multipurpose ruler, comprise perpendicular chi and crossfoot, perpendicular chi is vertically arranged with chute, crossfoot is slidingly connected by hinged bearing pin and perpendicular chi chute thereon, be hinged with arbitrarily angled chi at bearing pin, end face is provided with the angle index line on the bearing pin, and crossfoot is vertical with perpendicular chi, and perpendicular chi and crossfoot surface are provided with scale.The perpendicular chi of the utility model utilization can be drawn vertical line, because therefore crossfoot can move up and down and can draw parallel lines easily along perpendicular chi, end face is provided with the angle index line on arbitrarily angled chi and the bearing pin owing to being hinged with at bearing pin, and oblique line easily at any angle therefore can draw.Has setting-out simple in structure, practical and convenient advantage accurately.
Description of drawings:
Fig. 1 is the utility model front view.
The specific embodiment:
A most preferred embodiment of the present utility model, as figure, teaching setting-out multipurpose ruler, comprise perpendicular chi 1 and crossfoot 2, perpendicular chi is vertically arranged with chute 5, and crossfoot is slidingly connected with perpendicular chi chute 5 by hinged bearing pin 4 thereon, be hinged with arbitrarily angled chi 3 at bearing pin, end face is provided with angle index line 6 on the bearing pin, and crossfoot is vertical with perpendicular chi, and perpendicular chi and crossfoot surface are provided with scale.During use, the push-and-pull crossfoot can mark many parallel lines easily; Be provided with the angle index line by end face on the bearing pin and rotate arbitrarily angled chi 3 oblique line at any angle that just can draw.

Claims (1)
