Description
Technical field
The utility model relates to a kind of ruler of learning use, particularly a kind of multi-functional ruler-compasses serving many purposes.
Background technology
Ruler is that the frequency of utilization of student study article, particularly ruler, compasses and protractor of indispensability in the time of study geometric figure is high especially.But various rulers used are the special drawing tools of function singleness at present, student needs ceaselessly rotation to use various rulers in mapping process, not only affects mapping speed, and many rulers carry also inconvenient.In addition, although general independent compasses can meet the requirement of making circle, need to measure radius of a circle by means of ruler, and also doing in round process to cause the circle that draws irregular because of compasses unstable.
For above-mentioned deficiency, a kind of multi-functional ruler-compasses that can set in one of a variety of uses need to be provided, can realize the function of ruler, compasses and protractor simultaneously, improve the speed of mapping, and be convenient to student and carry.
Utility model content
In view of this, the utility model provides a kind of multi-functional ruler-compasses, sets in one of a variety of uses, easy to use, and the student who is suitable for each stratum uses at age, and it is simple in structure, and mapping efficiency is high.
The utility model solves the problems of the technologies described above by following technological means: a kind of multi-functional ruler-compasses, comprise that semi-circle ruler and lower end are provided with the vertical ruler of pilot pin, also comprise horizontal lattice chi and vertical bar shaped pen, described ruler dative chi one connects, the elastic interlayer structure that described semi-circle ruler dative chi is integrated, between the friction tight interlayer that is arranged at semi-circle ruler dative chi of described bar shaped pen, bar shaped pen can be along lattice chi lateral displacement.
Further, described interlayer lattice chi is provided with horizontal bar shaped slide opening, and described bar shaped pen is provided with longitudinal spacing lug, and bar shaped pen is by the displacement in bar shaped slide opening of spacing lug, and described spacing lug outside is provided with the nut that can withstand lattice chi.
Further, described bar shaped is held in the works and is provided with movable pen clip, and nib and the pilot pin of described pen clip are positioned at same level.
Further, described semi-circle ruler dative chi is the sandwich that stainless steel material is made.
Further, the forward of described semi-circle ruler, ruler and lattice chi be equipped with dorsad scale value.
The beneficial effects of the utility model: multi-functional ruler-compasses of the present utility model, comprise that semi-circle ruler and lower end are provided with the vertical ruler of pilot pin, also comprise horizontal lattice chi and vertical bar shaped pen, described ruler dative chi one connects, the elastic interlayer structure that described semi-circle ruler dative chi is integrated, between the friction tight interlayer that is arranged at semi-circle ruler dative chi of described bar shaped pen, bar shaped pen can be along lattice chi lateral displacement.Semi-circle ruler is connected with vertical ruler one by lattice chi, has realized protractor and the function combining with ruler; In ruler lower end, pilot pin is set, semi-circle ruler dative chi is arranged to the elastic interlayer structure that one connects, coordinate ruler can play the effect of compasses by being arranged at friction tight bar shaped pen between interlayer.In addition, because bar shaped pen can, along lattice chi lateral displacement, can be determined and be made radius of a circle by the scale value on lattice chi, easy to use, mapping efficiency is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the friction tight structural representation of an interlayer body of bar shaped pen and semi-circle ruler and lattice chi.
The specific embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in the figure: the multi-functional ruler-compasses of the present embodiment, comprise that semi-circle ruler 1 and lower end are provided with the vertical ruler 2 of pilot pin 3, also comprise horizontal lattice chi 4 and vertical bar shaped pen 5, described ruler dative chi one connects, the elastic interlayer structure that described semi-circle ruler dative chi is integrated, between the friction tight interlayer that is arranged at semi-circle ruler dative chi of described bar shaped pen, bar shaped pen can be along lattice chi lateral displacement.Described semi-circle ruler is equivalent to the function of protractor, lattice chi is coordinated to bar shaped pen and can realize the function of compasses with the ruler of pilot pin, because semi-circle ruler dative chi is the elastic interlayer structure of one, be arranged in interlayer friction tight bar shaped pen, arrange simple in structurely, be convenient to the lateral displacement of bar shaped pen in interlayer.In addition, because bar shaped pen can, along lattice chi interlayer lateral displacement, can be determined and be made radius of a circle by the scale value on lattice chi, definite radius value precision is high, and mapping is convenient, and efficiency is high.For the elastic interlayer structure of semi-circle ruler dative chi, should guarantee that its elasticity can tightly clamp bar shaped pen, guarantee the stability that bar shaped pen is held, lattice chi interlayer is near one section of structure that is integrated of ruler, it is the front and back double-layer structure not sealing that lattice chi opposite side can keep, to strengthen the elasticity of lattice chi and semi-circle ruler sandwich.
As the further improvement of technique scheme, described interlayer lattice chi 4 is provided with horizontal bar shaped slide opening 6, described bar shaped pen 5 is provided with longitudinal spacing lug 7, and bar shaped pen is by the displacement in bar shaped slide opening of spacing lug, and described spacing lug outside is provided with the nut 8 that can withstand lattice chi.Bar shaped slide opening is set on lattice chi, coordinate the spacing lug on bar shaped pen can make the displacement in the horizontal of bar shaped pen stable, fix fast in radius of a circle position, make circular velocity fast, but also can make bar shaped pen dative chi after spacing lug rotates angled, be convenient to coordinate semi-circle ruler to measure the number of degrees at angle; The nut in spacing lug outside is also positioned at the both sides, front and back of lattice chi simultaneously, has limited the relative position of a bar shaped dative chi interlayer, has strengthened the two friction tight effect.
As the further improvement of technique scheme, described bar shaped is held in the works and is provided with movable pen clip 9, and the nib of described pen clip and pilot pin 3 are positioned at same level.Bar shaped is held in the works movable pen clip is set, and is convenient to change pen core, and nib and pilot pin are positioned at same level can be made the circle of making standard is clean and tidy all the time.
As the further improvement of technique scheme, the sandwich that described semi-circle ruler 1 dative chi 4 is made for stainless steel material.Stainless steel material is easy to obtain, and the laminated structure good springiness of making, and is difficult for being fractureed, practical.
As the further improvement of technique scheme, the forward of described semi-circle ruler 1, ruler 2 and lattice chi 4 be equipped with dorsad scale value.Positive and negative two faces at semi-circle ruler, ruler and lattice chi all arrange after scale value, can reduce the number of times of conversion ruler when mapping, are convenient to fast drawing, have strengthened practicality.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
