Abstract

The utility model relates to a multi-purpose pupil rule which belongs to a multifunctional study tool. A long circular rolling shaft printed with multipliers and results in multiplication calculation is respectively sheathed in small circular holes at both ends of a rule body with a bulge through small shafts which are projected on rollers at both ends of the rolling shaft. The bulge part of the rule body is provided with ten small square holes. The upper parts of the small square holes are printed with the numbers from zero to nine. When the rule is used, a wheel shaft is rotated, different multipliers and results can be respectively observed through the small square holes. The wheel shaft can be pushed in parallel. The perpendicular plane of the multi-purpose rule can be used for drawing parallel lines and vertical lines with different width. The utility model combines knowledge and the study tool into a whole, which is good for the study of pupils.

Description

Multi-purpose pupil rule

The utility model relates to a kind of student's schooling apparatus, and particularly a kind of can study be consulted one to nine multiplication calculated data, can get the multi-functional chi of using of pupil of the parallel lines of different in width again easily.

Existing confession pupil learns used chi, and general most all is to be printed on outside the scale on the ruler, prints a little little patterns or how much patterns again, strengthens children's interest with this, but can not provide more study purposes and convenient for the pupil.

The purpose of this utility model provides a kind of span routing that gets final product, and can learn to consult one to nine multiplication calculated data again, and the pupil that can also get the different in width parallel lines quickly and easily uses chi.This chi is according to pupil's needs in doing the homework at ordinary times, trundle below ruler is the multiplication pithy formula printed according to certain rules of parallel promotion and roller bearing up and down, the setting-out and consult simple multiplication total but convenient for children is drawn squares, for children provide convenience in study, again because the shape of this chi is used chi far different than general student, very unique, collection arithmetic and schooling apparatus are one, and the learning interest that can promote children again easy to carry of going to school is liked very much.

The purpose of this utility model is achieved in that below a rectangle that is made of plastics has the blade of protuberance, assembles the roller bearing of a length less than blade.Roller bearing is by the little axle that protrudes on two rollers that are enclosed within two ends, is set in the small sircle hole at blade protrusion two ends.Roller cooperates tighter with roller bearing, can rotate synchronously.Because blade is higher than roller, when promoting blade, the roller at two ends can synchronous parallel rotation.With pen at the blade parallel lines that can get different in width of facing directly in front.If with nib broadcast blade face directly the middle part small sircle hole in, can also get vertical line with moving up and down of ruler.Roller bearing is printed on the different digital of arranging by multiplication pithy formula.Multiplier is on a left side, and product on the right.On the blade ridge, the numeral of aiming on the roller bearing has ten small square holes.Multiplicand is imprinted on ten small square hole tops respectively.When promoting blade, according to different multipliers, the contrast multiplicand can be seen one to nine multiplication total respectively from small square hole with the rotation of roller bearing.The student can check operation and study with this chi.

Accompanying drawing is a floor map of the present utility model, assembling and part sectioned view.Further specify utility model below in conjunction with accompanying drawing.

Fig. 1 is pupil's 99 multipurpose rulers assembling part sectioned view.

Fig. 2 is pupil's 99 multipurpose ruler floor map.

As shown in the figure, pupil's 99 multipurpose rulers can be made with rigid plastics.By a roller bearing (1) that is printed on one to nine multiplication total, two ends are with diameter and are through in the small sircle hole (4) at blade protrusion two ends greater than the little axle (3) that the roller (2) of roller bearing protrudes by the roller two ends.Make whole blade (9) be higher than the minimum point of roller.As shown in Figure 1.Roller and roller bearing can rotate synchronously.The multiplicand (6) that is imprinted on the square hole top by the contrast of ten square holes (5) on the blade ridge just can be seen different multipliers (11) and total (10) respectively.With face directly (7) of blade front end, can get horizontal line.Promote roller and can get the parallel lines of different in width.If nib is broadcast at blade front end circular hole (8), promote roller and can get vertical line.Be printed on the chi millimeter and centimetre scale.

Claims

1, a kind of pupil's apparatus, particularly a kind of pupil's 99 multipurpose rulers that have multiplication pithy formula, it is characterized in that: by one be printed on one to nine multiplication calculate in the microscler round roller bearing of multiplier and different totals, the roller bearing two ends are with the circle roller of diameter greater than roller bearing, by taking turns the little axle that protrudes, be set on respectively in two small sircle holes at blade ridge two ends, ten small square holes are arranged above the blade ridge, small square hole top is printed on 1 to 9 numeral.

2, pupil's 99 multipurpose rulers according to claim 1, it is characterized in that one is made rectangular with rigid plastics, its rear portion has the ruler of protuberance, there is the microscler circular shaft of roller at two ends of assembling below protuberance, be printed on the multiplier of 1-9 and different totals on the axle, roller and roller bearing can rotate synchronously, it is parallel mobile to drive simultaneously blade, the numeral of being printed on the roller bearing, can be with the rotation of axle, the front end of blade is for facing directly, on millimeter and centimeter scale are arranged, the middle part has a small sircle hole, whole blade to be higher than the minimum point of surface roller down.
