Abstract
The utility model relates to a novel combined angle gauge which comprises an inner angle measuring gauge and an outer angle gauge that are composed by a scale plate and a measurement plate. Graduations of an arc chord angle are arranged on the scale plate, the measurement plate is positioned above the scale plate, and the scale plate and the measurement plate are movably connected with the center of a circle by a set screw. The utility model has simple and firm structure, low cost, convenient and fast operation and visual display. The requirement of angle measurement of the general engineering can be satisfied.
Description
The utility model is a kind of measuring instrument, specifically, is the combination bevel protractor that takes measurement of an angle on a kind of engineering.
At present, the bevel protractor complex structure that uses on the engineering, precision height, cost is big, and complex operation step does not still have the low bevel protractor of a kind of cost can satisfy the measurement of angle needs of the not high common engineering of precision.
The utility model is to propose at above-mentioned deficiency, and its purpose is to provide simple in structure, cost is low, a kind of combination bevel protractor of convenient to operation, intuitive display.
Bevel protractor and outer bevel protractor in this novel combination bevel protractor comprises, technical scheme is:
1, interior bevel protractor by scaleplate, is measured plate and is formed, and 90 °-180 ° arc chord angle scale is arranged on the scaleplate, measures the top that plate is positioned at scaleplate, with set screw with both at the circle centre position link joint.
2, outer bevel protractor is made up of scaleplate, measurement plate, and 0 °-180 ° arc chord angle scale is arranged on the scaleplate, measures the top that plate is positioned at scaleplate, uses set screw the central point of measuring plate and the center of circle link joint of scaleplate.
Provide accompanying drawing of the present utility model:
Accompanying drawing 2 is the surface structure synoptic diagram of the outer bevel protractor of the utility model
Among the figure: 1 scaleplate, 2 is measured plate, 3 set screws, 4 arc chord angle scales, 5 slotted lines
Now narrate implementation method of the present utility model in conjunction with the accompanying drawings:
The utility model mainly is made up of scaleplate 1, measurement plate 2.
1, interior bevel protractor Fig. 1, scaleplate 1 has arc chord angle scale 4 for the angle becomes 90 ° covering of the fan on the covering of the fan, scale is 90 °-180 °, measure plate 2 and be the identical covering of the fan of size and scaleplate 1, measurement plate 2 is positioned at the top of scaleplate 1, usefulness set screw 3 with both at the circle centre position link joint.
2, outer bevel protractor Fig. 2, scaleplate 1 has arc chord angle scale 4 for the angle becomes 180 ° covering of the fan on the covering of the fan, scale is 0 °-180 °, measuring plate 2 is rectangle, measures the top that plate 2 is positioned at scaleplate 1, measures the central point of plate 2 and the center of circle link joint of scaleplate 1 with 3 of set screws.
The utility model use-case: when angle measurement is spent, get the combination bevel protractor make it scaleplate 1 want measured angular while being close to, measure one side of plate 2 and be close to the another side of wanting measured angular, slotted line 5 indication angle on scaleplate 1 is the angle of the measured angular of wanting, interior bevel protractor can the survey scope be 90 °-180 ° a interior angle, and outer bevel protractor can the survey scope be 0 °-180 ° exterior angle.
The utility model is simple in structure, cost is low, easy and simple to handle, intuitive display, satisfies the measurement of angle needs of the not high common engineering of precision, especially adapts to vast rural market.
