Abstract
The utility model provides a folding geometrical ruler set which consists of a handle ruler, a protractor, a sliding chute ruler and a connecting ruler, wherein, a protruding handle is arranged in the middle of the handle ruler, the left surface of the handle is provided with the protractor, the left end part of the handle ruler is movably connected with the sliding chute ruler, the outer edge of the sliding chute ruler is provided with a scale mark, the top end of the sliding chute ruler is provided with a chalk sleeve, the ruler body of the sliding chute ruler is provided with the sliding chute, a protruding connecting shaft is connected inside the sliding chute and is connected with one end of the connecting ruler, the other end of the connecting ruler is movably connected with the right end of the handle ruler, and the right end part of the handle ruler is in a needle tip shape. The folding geometrical ruler has the advantages that the structure is simple, when a straight line is drawn, the sliding chute ruler can be used directly; when an angle needs to be measured or to be drawn, the handle ruler and the sliding chute ruler as well as the connecting ruler are pulled out; when the ruler is taken as a compass, the right end part of the handle ruler is taken as the center of a circle, and the chalk is arranged inside the chalk sleeve on the sliding chute ruler.
Description
Technical field:
The utility model belongs to the mathematical education articles for use, particularly collapsible dimensioning.
Background technology:
In several teaching, often need to draw various geometric figures, at this moment teacher often needs to carry instruments such as set square, compasses and protractor, and is also cumbersome when carrying, and also will change every now and then during use, uses also more time-consuming.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of collapsible dimensioning is provided, said collapsible dimensioning is achieved in that collapsible dimensioning is by the handle chi, protractor, the chute chi be connected chi and form, be provided with outstanding handle in the centre position of handle chi, the left side at handle is provided with protractor, be connected with the chute chi in the left part of handle chi, the outer of chute chi is provided with graduation mark, be provided with chalk sleeve on chute chi top, on the blade of chute chi, be provided with chute, be provided with outstanding connecting axle in the chute, connecting axle connects with an end that is connected chi, the other end that connects chi is connected with the right-hand member of handle chi is movable, and the right-hand member end of said handle chi is a tip-like.
A kind of connection chi of collapsible dimensioning is a telescopic structure, in the both sides of the base plate that connects chi pit is set, and the slide plate that connects chi is provided with the boss that cooperates with pit.
The advantage of collapsible dimensioning is: simple in structure, in application, when drawing straight line, can directly use the chute chi, also can make handle chi, chute chi and be connected chi to fold and re-use the chute chi, when needs take measurement of an angle or draw the angle of certain angular dimension, handle chi, chute chi and be connected chi and draw back and get final product again, do the compasses time spent, then the right-hand member end with the handle chi is the center of circle, gets final product behind the chalk of packing in the chalk sleeve on the chute chi.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is the structural representations that connect chi: 1-handle chi 2-handle 3-protractor 4-chute chi 5-chute 6-chalk sleeve 7-connects chi 8-base plate 9-pit 10-slide plate 11-boss
The specific embodiment:
Be described as follows with reference to accompanying drawing 1: collapsible dimensioning is by handle chi 1, protractor 3, chute chi 4 and be connected chi 7 and form, be provided with outstanding handle 2 in the centre position of handle chi 1,, be provided with protractor 3 on the left side of handle 2 with convenient hand-held, the size of protractor 3 should not be too big, can make transparence; Be connected with chute chi 4 in the left part of handle chi 1, the outer of chute chi 4 is provided with graduation mark, be provided with chalk sleeve 6 on chute chi 4 tops, on the blade of chute chi 4, be provided with chute 5, said chute 5 is preferably bending, with the convenient slip that connects chi 7, in chute 5, be provided with outstanding connecting axle, connecting axle connects with an end that is connected chi 7, also will do movable connection here, the other end of said connection chi 7 is connected with the right-hand member of handle chi 1 is movable, and the right-hand member end of said handle chi 1 is a tip-like, conveniently to do the compasses time spent, be the center of circle with this end.In order to make handle chi 1, chute chi 4 and to be connected the convenience that chi 7 folds, connect chi 7 and make telescopic structure, that is to say in the both sides of the base plate 8 that connects chi 7 pit 9 is set, the slide plate 10 that connects chi 7 is provided with the boss 11 that cooperates with pit 9, boss 11 embeds in the pit 9, can make base plate 8 and slide plate 10 capable of expansion and contraction, to adapt to different folding needs.
Collapsible dimensioning is simple in structure, in application, when drawing straight line, can directly use the chute chi, also can make handle chi, chute chi and be connected chi to fold and re-use the chute chi, when needs take measurement of an angle or draw the angle of certain angular dimension, handle chi, chute chi and be connected chi and draw back and get final product again, do the compasses time spent, then the right-hand member end with the handle chi is the center of circle, gets final product behind the chalk of packing in the chalk sleeve on the chute chi.
