Description

A kind of practical vernier angle measuring instrument

Technical field

The utility model relates to a kind of survey instrument, relates to or rather a kind of Novel angle degree survey instrument.

Background technology

Measurement of angle is the important component part of geometry metrology technology, measuring method has a lot, what precision was lower has protractor method, and accurately high have transit method, optical dividing head method, multifaceted prism body method, photoelectric encoder method, diffraction approach, autocollimation method, circle raster method, a loop laser method etc.For charting or the instrument of the measurement of angle of real work also has a lot, as protractor, transit, Multifunctional angle scale, electronic type bevel protractor etc., but most instrument cannot measure required angle value in some occasions rapidly and accurately because of the both sides that cannot be directly adjacent to angle.Although electronic type bevel protractor can measure near the both sides at angle, expensive, when use, need meticulously, to be in fear of to damage because of improper use.And some engineering sites, need especially engineering technical personnel to measure fast and accurately angle, convenient design and calculating, as the top angle of the angle between two sides, bellmouth, the angle of dovetail groove or the angle in some special places, cannot measure with the both sides that protractor is directly adjacent to angle, this just need to measure angle and the length that can measure with protractor and length ruler, convert or calculate after obtain, waste time and energy, cannot directly read angle value, or contrast and estimate angle value with sample Angle formwork, sometimes also need many people to coordinate, extremely inconvenient.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art a kind of practical vernier angle measuring instrument is provided, simple to operate, is easy to carry, and directly reading, measurement fast, can effectively be increased work efficiency.

The utility model is characterised in that: comprise dip stick I, dip stick II, reading ruler I, reading ruler II, described reading ruler I, reading ruler II is slightly longer than dip stick I, dip stick II; Described dip stick I, dip stick II are the ruler of two ends semicircular in shape; Described reading ruler I one end is semicircular ruler, and the other end is circular 360 ° of protractors, the protractor center of circle on the center line of semicircular ruler, protractor taking the center line of semicircular ruler as zero graduation, reading clockwise; Described reading ruler II one end is semicircular ruler, the vernier that the other end is circular arc, and vernier is taking the center line of semicircular ruler as zero graduation, as clockwise reading, and 49 ° are divided into 50 parts, and reading marks respectively 0 by 5 multiple, 1,2,3,4,5,6,7,8,9,0; The center of arc of described dip stick I, the two ends of dip stick II and the semicircular ruler end of reading ruler I, reading ruler II and the center of circle of protractor, vernier is eyeletting respectively, aperture is on the center line of ruler, connect between any two composition rhombus support with mandrel head and the tail at aperture place.

Principle of work: when measurement, first dip stick I, dip stick II are leaned against respectively on the both sides that will take measurement of an angle, now at angle, this angle is the number of degrees value of institute's measuring angle for the round zero graduation line of inclinometer and the zero graduation line of vernier.For the measurement of dovetail groove two inclined-plane angulations or some back taper angle of spot holes, the dip stick I that can dismantle, dip stick II, be directly close to two inclined-planes at dovetail groove or back draught angle with the both sides of reading ruler I, reading ruler II, directly read angle value.

Technique scheme is known, the utility model is novel, utilize rhombus diagonal angle to equate with the principle of four connecting rods, the angle that is difficult for measuring to be borrowed to the diagonal angle being convenient for measuring, utilize vernier to improve the accuracy of measuring, can be applied to extensively, quickly and easily the measurement of the angle of various different stations, as capital construction, device fabrication, naval vessel setting-out, aircraft manufacturing and military field etc.1, be convenient for carrying, can meet any many kinds of work position, the measurement requirement under varying environment.2, direct reading, and do not need to convert and calculate, even also can use easily without the layman of professional knowledge.3, reading accuracy is high, and 0.02 ° of angle-differentiated value, can reach every minute and second level, meets the requirement that very big part engineering construction is measured.4, coordinate without many people, save manpower.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is application schematic diagram of the present utility model.

In figure, 1. dip stick I, 2. dip stick II, 3. reading ruler I, 4. reading ruler II, 5. mandrel.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model comprises angle measuring scale I 1, dip stick II2, the reading ruler I 3 of band circle inclinometer and reading ruler II4, the mandrel 5 with vernier.Described reading ruler I 3, reading ruler II 4 is slightly longer than dip stick I 1, dip stick II2.

Described dip stick I 1, dip stick II 2 are the ruler of two ends semicircular in shape; Described reading ruler I 3 one end are semicircular ruler, and the other end is circular 360 ° of protractors, and the protractor center of circle is on the center line of semicircular ruler, and protractor is taking the center line of semicircular ruler as zero graduation, and reading direction is clockwise; Described reading ruler II4 one end is semicircular ruler, the vernier that the other end is circular arc, and vernier is taking the center line of semicircular ruler as zero graduation, and reading direction is that 49 ° are divided into 50 parts clockwise, and reading marks respectively 0 by 5 multiple, 1,2,3,4,5,6,7,8,9,0.

The ruler partial width of described dip stick I 1, dip stick II 2 and reading ruler I 3, reading ruler II 4 equates.The center of arc of described dip stick I 1, the two ends of dip stick II 2 and the semicircular ruler end of reading ruler I 3, reading ruler II4 and the center of circle of protractor, vernier is eyeletting respectively, aperture is on the center line of ruler, half circular diameter is ruler width, and the ruler partial width of described dip stick I 1, dip stick II 2 and reading ruler I 3, reading ruler II 4 equates.
