Abstract

The utility model relates to a multipurpose intelligent ruler implement which is the improvement of stationery overcoming the defect of the oneness of the existing stationery. The utility model is a combination of a straightedge, a set square, and a protractor, and can draw an arc shape, a curve, a star shape, and a gear shape, and has a group of marked external gears. Because the multifunctional ruler is combined with the external gears, the utility model has the advantages of practicality, intelligence, great interest, novel design, and multiple functions (such as the function of an ordinary straightedge, the function of a set square and the function of a protractor). The utility model can be used for drawing such as circular drawing, arc drawing, curve drawing, etc. When the multipurpose intelligent ruler implement is matched with the external gears, an equidirectional mechanical transmission system or a reverse mechanical transmission system can be formed, so the utility model which is also suitable for children can be assembled into a toy vehicle, and can draw multiple colored patterns.

Description

Multipurpose intelligent rule implements

The utility model is the improvement that belongs to cultural tools,

The ruler that existing students in middle and primary schools use, angle square, protractor etc. mostly are monolithic entity, and its weak point is that purposes is single, lack knowledge, recreational, deposit also inconvenient.

The utility model provides a kind of tool practicality, intellectual, interesting in the wisdom multipurpose ruler tool of one for cultivating students in middle and primary schools' learning science cultural knowledge interest.

The utility model is to realize like this, multipurpose ruler is made with plastics or metal and is integrated ruler, set square, protractor, arc, curve, star, gear shape, chi is provided with nine tape labels (A, B, C, D, E, A1, D1, E1, E2) aperture, the outer supporting external gear that one group of tape label (A, B, C, D, E) arranged of chi, multipurpose ruler is used in combination with external gear, constitutes an apparatus, knowledge, amusement in the multipurpose ruler tool of one.The external gear of one group of supporting tape label, be to be made by plastics or metal, external gear is not of uniform size, and the module of each gear is identical, the number of teeth has 24,27,30,34 and 40 teeth etc. respectively, and each external gear is provided with the aperture of different the inserted atom pen core of quantity.

Following the description of the drawings:

Fig. 1 is the multipurpose ruler plane, (1) tape label A, B among the figure ... aperture.

Fig. 2 is the external gear picture group, and A side-looking (1) gear pillar among the figure, is looked up (1) and inserted atom pen core aperture B.

Fig. 3 is multifunctional combined chi tool plane.

The utility model embodiment describes its characteristic effect and advantage in conjunction with the accompanying drawings in detail, the utility model, design novel, purposes is various, both had common ruler, set square, the protractor function, the garden arc of can drawing a picture again, curves etc. are drawn and are used, if with external gear A, B, C, D, E inserts respective markers aperture on the chi respectively, promptly constitute an ascending machine driven system in the same way easily, with pinion A, for input initiatively crop rotation just (instead) to rotation, gear of output end E then, just just make (instead) to rotating at a slow speed, otherwise, gear E is the input driving wheel, the gear A of output then becomes fast rotational, if with gear A, D, E inserts A1 respectively, D1, the E1 aperture, promptly constitute a reverse drive system, as long as transmitting gear D, then gear A and E can do the rightabout rotation, above-mentioned two groups of machine driven systems can be given Preliminary study and the understanding of children student to theory of mechanics; If in the external gear any one put into multipurpose ruler internal gear (gear down), ball-point-pen core is inserted in any one hole of external gear, and external gear is tightly walked about along internal gear, various colored shapes can be drawn, if use the different colours pen core, then more can be full of endless joy; If with external gear D, insert on the D1 index aperture in the chi, external gear B, C insert respective markers in the chi, gear A inserts in the back side that mark A and gear E insert in mark E, promptly be assembled into one one five and take turns the toy car, the wheel of this car varies, and there have height to have to be low, as if very strange, but can park reposefully, strange thing enjoyment can be induced children's students ' imagination, the utility model utmost point is applicable to children, pupil, also is suitable for the drawing personnel and uses.

Claims
