Abstract
The utility model discloses a precision angular instrument, which is a tool used for exactly measure the included angle of the inclined surface, or the straight line and the horizontal surface. The precision angular instrument is composed of a rule base (1), a graduated disk (2), a pointer (3), a heavy hammer (4), a sliding ring (5), a central shaft (6), a clamping cap (7), a positioning ring (8), a supporting block (9), a braking rotary knob (10), a transparent window (11), an air bubble (12), and a line measuring groove (13). The precision angular instrument has high measuring precision, and the error is not greater than 1 DEG. The measurement is convenient; so long as the precision angular instrument is arranged on the measured inclined surface or the straight line, the precision angular instrument can directly read the included angles of the inclined surface, or the straight line and the horizontal surface. The precision angular instrument has the advantages of simple structure, easy fabrication, and wide purposes.
Description
Precision goniometer is the instrument of the angle of a kind of accurate measurement inclined-plane or straight line and surface level.
In the prior art, the instrument that is used to take measurement of an angle has protractor, surveyor's staff, transit, spirit-leveling instrument, geologic compass etc.Protractor is mainly used in the plane drawing.Whether surveyor's staff can only judge whether level of measurand between two parties by bubble in the liquid, can not measure out the concrete numerical value of angle.Transit, spirit-leveling instrument are mainly used in engineering and geodetic surveying.Geologic compass is mainly used in geologic survey.
In the real work, as usually running into the problem of the angle (claiming the inclination angle herein) that is difficult to measure inclined-plane or straight line and surface level in device fabrication, construction work, highway engineering, railway engineering and the daily life, be sought after a kind of survey instrument of precision, measure the inclination angle easily.The precision goniometer application of weight active line principle vertical with surface level that the utility model is released is just in order to reach this purpose.
Fig. 1 is the utility model profile synoptic diagram, and Fig. 2 is its structural representation.
As shown in the figure, the utility model is made up of rod support (1), index dial (2), pointer (3), weight (4), slip ring (5), axis (6), card cap (7), locating ring (8), back-up block (9), braking knob (10), transparency window (11), bubble (12), survey line groove (13).
Pointer (3), weight (4), slip ring (5) are fixedly connected as a whole, and the axis of pointer (3) is with the axis of weight (4) orthogonal (as shown in the figure) or overlap.Slip ring (5) is installed on an end of axis (6) and can freely rotates around axis (6), and the center of circle of the center of circle of slip ring (5) and axis (6) xsect coincides.Card cap (7) is fixedly connected on the end of axis (6).The center section of axis (6) and back-up block (9) are with being threaded.Back-up block (9) is fixedly connected on the rod support (1).Braking knob (10) is movably connected on the other end of axis (6) by screw thread.Index dial (2) is fixedly connected on the rod support (1), and the circumference of index dial (2) is divided into 360 five equilibriums, and one is divided into 1 °, and with the corresponding number of degrees of figure notation.Transparency window (11) is fixed on the rod support (1).Bubble (12) is installed on the end face (14) of rod support (1), and the major axis of bubble (12) pipe is vertical and parallel with axis (6) with side (16), (17) of rod support (1).The bottom surface (15) of rod support (1) must be parallel with the major axis of bubble (12) pipe with axis (6).Axis (6) and side (16), (17) are vertical.It is last and vertical with axis (6) that side line groove (13) is positioned at bottom surface (15).
Rod support (1) is made of timber or plastics or metal material, pointer (3), weight (4), slip ring (5), axis (6), card cap (7), locating ring (8), back-up block (9), braking knob (10) are made of metal material, and transparency window (11) is with glass or plastic production.
When using this utility model to measure the inclination angle on inclined-plane, rod support (1) is placed on the tested surface, the bottom surface (15) that is rod support (1) overlaps with tested surface, adjust the position of rod support (1), make bubble (12) placed in the middle, the stop knob (10) of outwarding winding makes weight (4) sagging naturally, and then the reading of pointer (3) is the inclination angle of the face of surveying.When measuring the inclination angle of straight line, then, repeat aforementioned measuring process and get final product as long as survey line groove (13) and tested straight line are coincided.
When not measuring, will brake knob (10) and screw, allow card cap (7) push down slip ring (5), weight (4) and pointer (3) and just can be braked.
This utility model has many advantages: measuring accuracy height, error do not exceed 1 °; Easy to use; Simple in structure, make easily; Of many uses.
