Abstract
A kind of slide calliper rule protractor relates to a kind of improvement of angle gage structure.The utility model provides a kind of a kind of slide calliper rule protractor can measured to solid concave or convex side angle.The utility model comprises protractor, first connecting rod, second connecting rod, third connecting rod and double leval jib, it is characterized in that: described first connecting rod is connected by the first rotating shaft being arranged on protractor center with second connecting rod one end; Third connecting rod one end connects the second connecting rod other end by the second rotating shaft, and one end of double leval jib connects the other end of third connecting rod by the 3rd rotating shaft, and the other end of double leval jib connects the other end of first connecting rod by the 4th rotating shaft; Extension rod is connected with at the other end of first connecting rod.
Description
Technical field
The utility model relates to a kind of improvement of angle gage structure.
Background technology
Protractor is various in style, is the indispensable survey instruments of students in middle and primary schools.Can draw angle, measuring angle, picture perpendicular line, parallel lines, survey degree of tilt, verticality, levelness, can work as inside and outside right angle and turn chi, open, close up, can work as length ruler can also comparatively really intuitively read, and draws the circle of given size.Product can three types processed: the small-sized stationery of protractor (main material is plastics) is practically applicable to pupils and students; Type B teaching aid (main material is plastics) is practically applicable to school teacher; C type instrument (main material is stainless steel metal) is practically applicable to factory, workshop, carpenter, skilled worker, repairman etc.As: teacher, pupils and students' doing mathematics, geometry and little makings or repairman needing carrying amount hornwork, set square, ruler, compasses and workman with surveyor's staff when measuring drafting, making, turning chi, estimating the above-mentioned measurers such as table.The use of visible energy hornwork is very universal also very convenient.
But, existing protractor be all in one plane angulation or draw angle, on a geometrical body angulation or draw angle then helpless.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of a kind of slide calliper rule protractor can measured to solid concave or convex side angle.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises protractor, first connecting rod, second connecting rod, third connecting rod and double leval jib, it is characterized in that: described first connecting rod is connected by the first rotating shaft being arranged on protractor center with second connecting rod one end; Third connecting rod one end connects the second connecting rod other end by the second rotating shaft, and one end of double leval jib connects the other end of third connecting rod by the 3rd rotating shaft, and the other end of double leval jib connects the other end of first connecting rod by the 4th rotating shaft; Extension rod is connected with at the other end of first connecting rod.
As a kind of preferred version, described protractor is circular protractor; Within one week of described circular protractor, be equipped with scale.
As another kind of preferred version, described first connecting rod, second connecting rod, third connecting rod, double leval jib and extension rod are transparent plastic connecting rod.Transparent plastic connecting rod is convenient aims at scale and edge alignment condition.
The utility model beneficial effect.
1, can the angle of measure geometry physically concave or convex.
During use, when measuring the dual-side angle concaved.Inserted by angle between third connecting rod and double leval jib in measured angle, the angle measured between first connecting rod and second connecting rod by the principle that parallelogram diagonal angle is equal can learn tested angle.During angle between the both sides measuring evagination, treat on the dual-side of angle measurement by being attached between the extension rod of first connecting rod and double leval jib, the angle being deducted first connecting rod and second connecting rod by 180 ° obtains treating measuring angle.Very easy to use.
2, can be used for picture angle
During use, throughput hornwork measures the angle between first connecting rod and second connecting rod, is then the angle between measured first connecting rod and second connecting rod with the side that pen connects third connecting rod and double leval jib.Convenient to use.
Accompanying drawing explanation
The technical matters solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with the drawings and the specific embodiments, are further elaborated to the utility model.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the utility model structural representation.
In figure, 1 be second connecting rod, 2 be protractor, 3 be first connecting rod, 4 be third connecting rod for extension rod, 5 be the first object under test, 6 be double leval jib, 7 is the second object under test, 8.
Embodiment
As shown in Figure 1, the utility model comprises protractor 2, first connecting rod 3, second connecting rod 1, third connecting rod 8 and double leval jib 6, it is characterized in that: described first connecting rod 3 is connected by the first rotating shaft being arranged on protractor 2 center with second connecting rod 1 one end; Third connecting rod 8 one end connects second connecting rod 1 other end by the second rotating shaft, and one end of double leval jib 6 connects the other end of third connecting rod 8 by the 3rd rotating shaft, and the other end of double leval jib 6 connects the other end of first connecting rod 3 by the 4th rotating shaft; Extension rod 4 is connected with at the other end of first connecting rod 3.
Described protractor 2 is circular protractor; Within one week of described circular protractor, be equipped with scale.
Described first connecting rod 3, second connecting rod 1, third connecting rod 8, double leval jib 6 and extension rod 4 are transparent plastic connecting rod.Transparent plastic connecting rod is convenient aims at scale and edge alignment condition.
Above content is the further description done the utility model in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
