The utility model discloses avoid pressing of mr, reduced intensity of labour, simultaneously at four ruling scales, four rulings of english of can painting out fast, at water cavity and horizontal bubble's the effect comparatively horizontally straight line that can draw up down, can improve operating speed like this, improved the efficiency of drawing.

Description

A kind of science teaching drawing rule

Technical field

The utility model relates to realia technical field, particularly relates to a kind of mathematics, physics teaching drawing rule.

Background technology

Teaching is the distinctive personnel training activity of a kind of mankind that the religion of teacher and of student form.

By this activity, teacher has object, planned and organized ground guiding student actively consciously to learn and accelerates to grasp Cultural Science rudimentary knowledge and basic skills, promotes that the many-sided quality of student improves comprehensively, makes them become people required for society.I.e. some training class, school, the service carried out.

Natural sciences refer to natural science, applied science and mathematical logic, opposed with literal arts, the natural sciences subject in middle school has: mathematics, physics, chemistry, biology, computer software application, geography, technology and PRACTICE OF DESIGN etc., the birth of natural sciences is the result that the wisdom of humanity develops with development, indicate that the mankind have really understood thinking nature, therefore the development of natural sciences is also the key that human sciences and natural thinking develop.

At present, when will draw in teaching process, existing drawing rule needs teacher to press drawing rule with hand in drawing course, cause troublesome poeration, efficiency is low, and be a teacher scribe step more complicated when needing to draw English four ruling simultaneously, occupy more time in classroom, affect teaching efficiency, and rely on when drawing straight line the naked eyes of teacher to draw straight line, the easy like this inclination causing rear straight line of drawing.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of science teaching drawing rule.

The utility model is achieved through the following technical solutions:

A kind of science teaching drawing rule, comprise horizontal drawing rule, described horizontal drawing rule two ends are provided with the vertical drawing rule vertically arranged, each vertical drawing rule described is provided with chute, described horizontal drawing rule both sides and vertical drawing rule upper end are equipped with fixing sucking disk on the surface near blackboard side, slide block is provided with in each chute described, described slide block is connected with attachable mechanical stage two ends, each vertical drawing rule described is provided with four ruling scales, described horizontal drawing rule, vertical drawing rule and attachable mechanical stage are provided with drawing scale, water cavity is provided with in the middle part of described horizontal drawing rule, described water cavity inside is provided with horizontal bubble.

As optimal technical scheme of the present utility model, described fixing sucking disk is fixedly connected with between horizontal drawing rule, vertical drawing rule.

As optimal technical scheme of the present utility model, the rectangular structure of described chute.

As optimal technical scheme of the present utility model, described water cavity is embedded on horizontal drawing rule.

Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging horizontal drawing rule, vertical drawing rule, attachable mechanical stage, fixing sucking disk and four ruling scales, when such teacher needs to draw on class, horizontal drawing rule is fixed on blackboard by fixing sucking disk, avoid the pressing of teacher, reduce labour intensity, at horizontal drawing rule, attachable mechanical stage can go out different straight line under the effect of vertical drawing rule, English four ruling can be drawn by rapid drawing at four ruling scales simultaneously, the straight line of comparatively level can be drawn under the effect of water cavity and horizontal bubble, service speed can be improve like this, improve the efficiency of drawing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1. horizontal drawing rule; 2. vertical drawing rule; 3. chute; 4. fixing sucking disk; 5. slide block; 6. attachable mechanical stage; 7. four ruling scales; 8. water cavity; 9. horizontal bubble.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.

A kind of science teaching drawing rule, comprise horizontal drawing rule 1, described horizontal drawing rule 1 two ends are provided with the vertical drawing rule 2 vertically arranged, each vertical drawing rule 2 described is provided with chute 3, described horizontal drawing rule 1 both sides and vertical drawing rule 2 upper end are equipped with fixing sucking disk 4 on the surface near blackboard side, and wherein said fixing sucking disk 4 is fixedly connected with between horizontal drawing rule 1, vertical drawing rule 2.Slide block 5 is provided with, the rectangular structure of wherein said chute 3 in each chute 3 described.Described slide block 5 is connected with attachable mechanical stage 6 two ends, each vertical drawing rule 2 described is provided with four ruling scales 7, described horizontal drawing rule 1, vertically drawing rule 2 and attachable mechanical stage 6 are provided with drawing scale, water cavity 8 is provided with in the middle part of described horizontal drawing rule 1, wherein said water cavity 8 is embedded on horizontal drawing rule 1, described water cavity 8 inside is provided with horizontal bubble 9, the straight line of the comparatively level of can drawing out like this.
