Abstract
The utility model provides a parallel line drawing aid for teaching, and relates to teaching appliances. The parallel line drawing aid comprises a fixed ruler (1), sucking discs (2), a sliding sleeve (3) and a movable ruler (4), and is characterized in that the sliding sleeve (3) adaptive to the fixed ruler (1) is sleeved on the fixed ruler (1) in a sliding manner, wherein the sucking discs (2) are respectively arranged on the bottom surfaces of the two ends of the fixed ruler (1); and the movable ruler (4) vertical to the fixed ruler (1) is connected to and fixed on the sliding sleeve (3). The parallel line drawing aid has a simple structure, is simple and convenient to operate, can be rapidly and conveniently used for drawing parallel lines with accurately positioned intervals on a blackboard, and can help students to better learn teaching contents, thereby improving the teaching efficiency.
Description
Technical field
The utility model relates to a kind of teaching aid, and specifically a kind of teaching is with parallel lines setting-out assistor.
Background technology
On the teaching classroom, often need teacher on blackboard, to draw parallel lines now, and the method for drawing parallel lines is at present normally used two set squares; Through wherein one on another set square, sliding set square and to draw; Its troublesome poeration is wasted time and energy, and the parallel lines of drawing are accurate inadequately; Also can't carry out the distance location, thereby reduce efficiency of teaching.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, and the teaching that can accurately locate spacing is with parallel lines setting-out assistor.
The purpose of the utility model is achieved in that this teaching is made up of fixed ruler, sucker, sliding sleeve, attachable mechanical stage with parallel lines setting-out assistor; The slip suit the sliding sleeve that adapts with it above the bottom surface, two ends was respectively equipped with the fixed ruler of sucker, connected above the sliding sleeve and was fixing the attachable mechanical stage vertical with fixed ruler.
During use, this device is absorbed and fixed on the blackboard, moves attachable mechanical stage according to the scale above the fixed ruler and can on blackboard, draw and meet the parallel lines that spacing requires through sucker.
The advantage of the utility model: simple in structure, easy and simple to handle, can on blackboard, draw quickly and easily to the pinpoint parallel lines of spacing, can help the better learning teaching content of student, improve efficiency of teaching.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: this teaching is made up of fixed ruler 1, sucker 2, sliding sleeve 3, attachable mechanical stage 4 with parallel lines setting-out assistor; The slip suit the sliding sleeve 3 that adapts with it above the bottom surface, two ends was respectively equipped with the fixed ruler 1 of sucker 2, connected above the sliding sleeve 3 fixing the attachable mechanical stage 4 vertical with fixed ruler 1.
