Description

A kind of digital drafting instrument
Technical field
This utility model belongs to mathematical education field, particularly to a kind of digital drafting instrument.
Background technology
At present, instructors at school time, for the most enough contents more intuitively telling about course, often use teaching aid Aided education, especially in the teaching process of mathematics geometry, is frequently used such as ruler, compasses, set square etc. and teaches Tool, but these teaching aids are mostly independent individuality, and ratio is relatively decentralized, and one is to be easier to lose;Two is teacher When mapping, need to change back and forth, waste the instructional blocks of time of preciousness, and add the workload of teacher.Always It, there is problems such as using complex steps, operation inconvenient in existing mathematics geometry teaching aid, brings one to teaching Fixed trouble.
Utility model content
In order to solve the problems referred to above, this utility model relates to a kind of digital drafting instrument, this drawing apparatus by graduated tile, Horizon rule, rotation chi are constituted, and the outer rim of graduated tile is carved with decile angle groove, and the plate face of graduated tile has been engraved Geometric figure;
Described horizon rule includes chi groove and horizontal extension ruler with a scale, and horizontal extension ruler is sliding in chi groove Dynamic, horizontal extension ruler can stretch out from chi groove, extends the length of horizontal extension ruler;
Described rotation chi structure includes rotating chi groove, rotational slide rail and knob, and knob is by rotating hinge structure structure Become;Described rotation chi groove and rotational slide rail are around knob, it is possible to have the merit of protractor and compasses concurrently simultaneously Can, rotate chi groove and be socketed outside rotational slide rail, thus rotational slide rail can stretch out from rotating chi groove, extends The length of rotational slide rail, the middle part, outer end of rotational slide rail is designed with slotted eye, is used for being set with placement chalk Or white board marker.
According to described digital drafting instrument, LED light emission device also can be set on graduated tile.
The beneficial effects of the utility model are: use this drawing apparatus can measure the angle of planar graph easily, Required angle can also be drawn easily, provide conveniently for mathematical education.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model digital drafting instrument;
Fig. 2 is the view during use of this utility model digital drafting instrument.
Detailed description of the invention
Understandable, below in conjunction with the accompanying drawings for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from Detailed description of the invention of the present utility model is described in detail, make above and other purpose of the present utility model, Feature and advantage will become apparent from.The part that reference instruction identical in whole accompanying drawings is identical, does not carve Anticipate accompanying drawing drawn to scale, it is preferred that emphasis is purport of the present utility model is shown, being capable of its major function be Preferably.
As illustrated in fig. 1 and 2, digital drafting instrument of the present utility model include semicircle or annular graduated tile 1, Horizon rule, rotation chi are constituted, and graduated tile 1 is semicircular structure, can be transparent, it is also possible to opaque;Carve Degree plate 1 can be made up of plastics, plank or lucite, and the outer rim of graduated tile 1 semicircular structure is carved with decile Angle groove 2, the semi-circular plate face of graduated tile 1 has been engraved multiple geometric figure 3, and described geometric figure can To include the structures such as ellipse, equilateral triangle, circle, square or right angled triangle, by the geometry engraved Figure can draw conventional geometric figure easily, demonstration when facilitating teachers ' teaching.
As in figure 2 it is shown, the horizon rule structure of described semicircle graduated tile 1 includes chi groove 8 and level with a scale Expansion ruler 9, horizontal extension ruler 9 can slide in chi groove 8, level can be utilized in teaching process to stretch The length of straight line measured by contracting ruler.
As it is shown in figure 1, the rotation chi structure of described semicircle graduated tile 1 includes rotating chi groove 4, rotational slide Rail 5 and knob 6, knob 6 is made up of rotating hinge structure;Described rotation chi groove 4 and rotational slide rail 5 enclose Rotate around knob 6, it is possible to jointly realize the function of protractor and compasses: can be by rotating chi groove 4 and chi groove 8 The angle constituted measures angle, such as a certain angle drawn on blackboard, and can straight by graduated tile 1 Linear outer rim and angle to be measured while aliging, rotational slide rail 5 aligns with the another side of angle to be measured, Then the angle groove indicated by rotational slide rail 5 is the reading of this angle;Fixing horizontal extension ruler 9 and chi Groove 8 is motionless, directly rotates and rotates chi groove 4 and rotational slide rail 5, it becomes possible to realizes the function of picture circle.
It addition, rotate chi groove 4 socket outside rotational slide rail 5, so that rotational slide rail 5 can be from rotation Turn in chi groove 4 and stretch out, so can by rotate chi groove 4 slide rotational slide rail 5 regulation circle radius big Little.It is designed with slotted eye 7 in the middle part, outer end of rotational slide rail 5, placement chalk or white board marker can be set with, It is used at blackboard or blank upper drawing circle.
It addition, for the angle drawing needs, horizontal extension ruler 9 card can be put in chi groove 8, rotate Slip rail 5 rotates to the scale corresponding to angle, such rotational slide rail 5, horizontal extension ruler 9 just group Become the angle needed, sketched the contours the angle that just can obtain needing by chalk line.
Further, in order to draw the longer angle of the length of side then can by rotational slide rail 5 from rotate chi groove 4 In stretch out, thus extend the length of rotational slide rail 5;Horizontal extension ruler 9 is stretched from chi groove 8 simultaneously Go out, thus extend the length of rotational slide rail 5, it is simple to draw the angle of larger skirt length.
It addition, LED light emission device can be arranged at graduated tile 1, for collecting the attention of middle school student in teaching process Power, improves teaching efficiency.
Elaborate a lot of detail in the above description so that fully understanding this utility model.More than but Describing is only preferred embodiment of the present utility model, and this utility model can be described herein to be much different from Alternate manner implement, therefore this utility model is not limited by disclosed above being embodied as.The most any Those skilled in the art, without departing under technical solutions of the utility model ambit, may utilize above-mentioned taking off Technical solutions of the utility model are made many possible variations and modification, or amendment by the method shown and technology contents Equivalent embodiments for equivalent variations.Every content without departing from technical solutions of the utility model, according to this practicality Novel technical spirit, to any simple modification made for any of the above embodiments, equivalent variations and modification, all still falls within In the range of technical solutions of the utility model protection.
