Description
Technical field
The utility model relates to measurement field of stationery, more particularly, relates to a kind of rule.
Background technology
Rule is student's requisite stationery in learning process.Student uses rule to measure the length of object, draws plane right-angle coordinate and rectangular coordinate system in space, completes various geometry exercise question.Meanwhile, in the process using lever rule, also rule will be used.The scale division value of rule is generally 1mm, and the rule range of general requirements is 10cm, 15cm and 20cm.At present, rule on market is generally suit, comprise a ruler (range is generally 20cm), two set squares (is the set square of isosceles right triangle, and another is the set square that three angles are respectively 90 °, 60 ° and 30 °) and a protractor.
Rule is in the market easy to the length measuring object, but also there are some problems.1, student is in the process doing exercise question, and due to the restriction that paper has living space, the scale being positioned at more than 10cm in fact seldom uses; 2, do in the process of exercise question and often will draw coordinate system, the data on coordinate system have just to be had negative, arranges negative value improper (length of object can not be negative) again, therefore use inconvenience in the range of rule; 3, some angles are had often to use when inscribing, such as 45 °, 60 °, 90 ° and 135 °, but the end of set square uses rear easy to wear for a long time, and it is very inconvenient that student will draw these angles fast; 4, in the process using lever rule to solve a problem, also will use rule, but the zero graduation of existing rule is positioned at one end of chi, causes and use inconvenience.Meanwhile, existing rule only can provide the function measuring length, and using function is more single.
Deficiency when using for existing rule, open relevant solution in prior art, as patent publication No.: CN201535964U, publication date: on July 28th, 2010, invention and created name is: Simple leverage ruler, this application case discloses a kind of physical teaching aid of energy assembling combination, the first rule that two block lengths are identical and one piece of second rule with track, assembled by technology, form relatively complete separate component, experimentally need, the first rule length can be regulated arbitrarily, reach the effect that experiment needs to prove, and it is simple to have structure, the advantage such as easy to carry.The weak point of this application case is: be not suitable for student and use when inscribing (exercise question about geometry, lever rule).
And for example patent publication No.: CN2049603U, publication date: on Dec 20th, 1989, invention and created name is: Universal straightedge, and this application case discloses a kind of Universal straightedge, belongs to geometry and makees figure instrument.This application case solves common ruler must borrow protractor, set square when being figure, and need by problems such as compasses in some occasion, the ruler of strip has centre zero scale, and Shi Yichi center is the symmetry distance scale of 0, and another side Shi Yichi center is the angle index of an angle of 90 degrees.The weak point of this application case is: near the angle index of an angle of 90 degrees, scale can become very close, thus causes use inconvenience.
Also as patent publication No.: CN87216788U, publication date: on August 24th, 1988, invention and created name is: box chi spring balance, this application case discloses the small instruments and tools for gauge length, weight in a kind of daily life, work, its principle is on the basis of box chi, utilize the elasticity of spring, composite design becomes can survey length again can the instrument of on measured weight.The weak point of this application case is: be difficult to quick-replaceable spring after spring breaking down, manufacturing cost is relatively high.
In sum, how designing a kind of applicable student and use when inscribing (exercise question about geometry, lever rule) and can serve as the rule of simple and easy spring balance, is a difficult problem of the prior art.
