Abstract
The utility model provides a multi-functional measuring device, which is characterized by comprising a first ruler, a second ruler and a protractor. The protractor, the first ruler and the second ruler are provided with corresponding chutes. A screw with a nut is adopted to connect the first ruler, the second ruler and the protractor together, and the protractor can slide in the chutes of the two rulers. With the improvement, the multi-functional measuring device helps students to understand the formation of an angle intuitively and visually, understand the definition of the angle and read the degree of the angel flexibly and accurately, enables students to intuitively and visually understand that two straight lines intersect to form adjacent supplementary angles and opposite angles and a straight line and a ray form adjacent supplementary angles, can accurately measure the size of a cone angle, an elevation angle and a depression angle, and can be used as a ruler, a protractor and the like. The multi-functional measuring device is strong in inapplicability, easy to take material and simple to manufacture.
Description
Technical field
The utility model relates to a kind of measurement of angle servicing unit, is specifically a kind of
Polymeter
Background technology
as everyone knows, the student is to geometrical learning the time, usually can use ruler, the schooling apparatus such as protractor, usually ruler is used for the picture straight line, line segment etc., protractor is used for study and the drafting at diagonal angle, measure etc., obvious traditional ruler function singleness relative to protractor, when the words of independent use amount hornwork to the angular measurement in various geometry the time obviously not easy to operate, and existing ruler, protractor just can not be used for other purposes except the function of itself, use can not be grouped together, for the beginner, the servicing unit that urgent hope has a kind of geometrical learning plays is convenient to geometric figure especially measurement and the study at angle.
The utility model content
The purpose of this utility model is to overcome existing middle not enough, provides a kind of at this
Polymeter,The number of degrees that can help the student to be familiar with intuitively, visually the formation at angle and definition and to read exactly the angle, thereby play auxiliary effect.
The utility model is achieved in that structure is a kind of
Polymeter is characterized in that: comprise firstRuler,
SecondRuler and protractor, described protractor,
FirstRuler and
SecondRuler is provided with corresponding chute, with a screw handle with nut
FirstRuler,
SecondRuler and protractor link together, and protractor can slide in the chute of two rulers.
According to described in the utility model a kind of
Polymeter, itsBe characterised in that: the place is provided with the weight line at described screw.
The beneficial effects of the utility model are: the utility model provides a kind of by improvement
Polymeter,This device can help the student to be familiar with intuitively, visually the formation at angle, understands the definition at angle, flexibly and accurately reads the number of degrees at angle; Allow visual pattern students ' understanding two straight lines intersect the adjacent supplementary angle that forms and vertical angle and straight line and the ray adjacent supplementary angle that consists of; Can measure exactly the size of cone angle; Can measure exactly the elevation angle and the angle of depression; Have the purposes such as ruler, protractor.This device applicability is strong, material is easily got, make simple.
Description of drawings
Fig. 1 is the utility model structural representation
In figure: 101,
FirstRuler, 102,
SecondRuler, 103, protractor, 104, chute, 105, screw, 106, the weight line.
Embodiment
Be described in detail below in conjunction with 1 pair of the utility model of accompanying drawing:
It is a kind of that the utility model provides
Polymeter, as shown in Figure 1; Comprise firstRuler 101,
SecondRuler 102 and protractor 103, described protractor 103,
FirstRuler 101 Hes
SecondRuler 102 is provided with corresponding chute 104, with one with 105, the screw of nut
FirstRuler 101,
SecondRuler 102 and protractor 103 link together, and protractor 103 can slide in the chute of two rulers.
105 places are provided with weight line 106 at described screw.
Operation one: protractor and rule Untie screw 105, just become independent protractor and ruler, have function separately.
Operation two: be familiar with the formation at angle and definition and understanding acute angle, right angle, obtuse angle, the straight angle and the round angle at angleScrew 105 slide into the chute other end (
FirstRuler 101,
SecondOne end of ruler 102), require three lines to overlap and screw, allow this moment
FirstRuler 101 is around screw 105 rotations, and two straight lines will form different angles, read immediately the number of degrees at each angle.
Operation three: demonstration two straight lines intersect formed angle, are familiar with adjacent supplementary angle and vertical angle, and understand their characterTake off two rulers and screw with screw 105 in midpoint, rotate arbitrarily a ruler and get final product.
Operation four: measure cone angleConical objects is placed on protractor and straight line
FirstBetween ruler 101, the angle of reading the place, place is the size of cone angle.
Operation five: measure the elevation angle and the angle of depression.103 rotations of upper figure protractor are come, allow the weight line overlap with 90 ° of scale marks, sight line and
FirstRuler 101 is consistent,
FirstRuler 101 is the elevation angle or the angle of depression with the formed acute angle of protractor 103.
