Abstract
The utility model provides a folding type angle ruler, which can be used for measuring lengths and angles, as well as drawing straight lines and angle lines. The folding type angle ruler consists of an angle measuring shaft and standard sections, wherein the angle measuring shaft passes through shaft holes in the standard sections to connect the two standard sections; under the action of external force, the standard sections can rotate around the angle measuring shaft to form any included angle. The folding type angle ruler has the beneficial effects that basic functions of an ordinary straightedge are improved, the measurement range of the straight ruler can be widened, functions of measuring the angles and drawing the angle lines are added to the angle ruler, the structure is simple, and the storage is convenient.
Description
Affiliated technical field
The utility model relates to a kind of measurement and drawing instrument, especially a kind ofly can measure length and angle, can also draw the chi of straight line and angle line.
Background technology
Ruler also have person be between chi, be a kind of measuring length instrument very commonly used, this instrument is very general, is generally used for measuring length and draws straight line.
At present, ruler is widely used in mathematics, measures, and aspects such as engineering are used for measuring length, draw straight line, detection etc.Ruler is used for carrying out straight line degree measurement and the measurement of planeness with light gap method, also can be used for the check length size with gauge block.Before the measurement, form two packet sizes with gauge block, one group of maximum limit of size that equals boss height dimension tolerance, another group equals the minimum limit of size.If with the former check, ruler seamed edge and boss surface contact position printing opacity; And when checking with the latter, ruler seamed edge and gauge block measurement face contact position printing opacity represent that then the boss height dimension is qualified.Ruler is used manufacturings such as rolling bearing steel, plastics, timber always, and length has specifications such as 50 millimeters, 100 millimeters, 300 millimeters, 1000 millimeters.
It is very difficult to take measurement of an angle with ruler, measures also difficulty of long length with very short ruler, and long ruler collection is inconvenient.
Summary of the invention
In order to overcome the existing ruler difficulty that takes measurement of an angle, short ruler is measured long length difficulty, and the problem of long ruler collection inconvenience is invented a kind of collapsible bevel protractor.
The technical scheme that its technical problem that solves the utility model adopts is: collapsible bevel protractor is made up of angulation axle and standard paragraphs, the length overall of collapsible bevel protractor determines that by the quantity of angulation axle and standard paragraphs collapsible bevel protractor is more long more at most to form the angulation axle of collapsible bevel protractor and the quantity of standard paragraphs.Be marked with the angle sign on the angulation axle, be marked with length mark on the standard paragraphs, the axis hole that the angulation axle passes on the standard paragraphs couples together two segment standard sections, and under external force, standard paragraphs can rotate around the angulation axle, forms any angle.Therefore, be a kind ofly can measure length and angle, can also draw the collapsible bevel protractor of straight line and angle line.
The beneficial effects of the utility model are, have improved the basic function of common ruler, can prolong the measurement category of ruler, have increased the function that ruler takes measurement of an angle and draws angle line, and are simple in structure, and collection is convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is practical ruler front view.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the left view of Fig. 2.
1. angulation axles, 2. axis hole, 3. standard paragraphs among Fig. 1.
The specific embodiment
In Fig. 2, will two segment standard sections (3) be linked together with the axis hole (2) that an angulation axle (1) passes on the two segment standard sections (3).If one the standard paragraphs of collapsible bevel protractor then couples together the multistage standard paragraphs according to above-mentioned method of attachment more than two sections.
Claims (1)
1. collapsible bevel protractor, it is characterized in that: collapsible bevel protractor is made up of angulation axle and standard paragraphs, is marked with the angle sign on the angulation axle, is marked with length mark on the standard paragraphs, and the axis hole that the angulation axle passes on the standard paragraphs couples together two segment standard sections.
