As shown in Figs. 1-2, a kind of rotational structure of measurable angle, including:Fixed part 100, rotation section 200, connecting portion
And measurement portion, wherein, the fixed part 100 has the first true edge 110 being mutually fitted with one side of tested angle, described
Rotation section 200 has for the second true edge 210 for be fitted with the another side of tested angle, and the connecting portion is with making rotation section
There is the angle for being arranged on 100 surface of fixed part to survey for 200 locating shafts 410 being rotatably connected with fixed part 100, the measurement portion
Structure is measured, which includes scale race 510 and cue mark 521, and the scale race 510 surrounds the locating shaft
410 central axis is arranged at intervals, and the cue mark 521 can be under the drive of rotation section 200 in the locating shaft 410
Mandrel line is rotated for rotation axis and corresponding scale mark in indicating graduation race 510, the scale mark of the cue mark 521 instruction
Corresponding scale value is equal to the size of the angle 300 formed at that time between the first true edge 110 and the second true edge 210.
One side of first true edge 110 and tested angle is mutually fitted by the rotational structure of above-mentioned measurable angle, when use,
The another side of the second true edge 210 and tested angle is fitted again, then passes through cue mark 521 in reading angle measurement structure
Indicated scale mark is the big decimal of the available angle 300 formed between first true edge 110 and the second true edge 210
Value, the numerical value are the angular values of tested angle.As it can be seen that the structure can very easily realize angular surveying, and by
The sideline of angle is surveyed without being directly directed at scale mark, can accurately measure very much angle in short-term in tested angle side line length
Degree.
In one embodiment of the utility model, the rotation section 200 and the end of locating shaft 410 are connected as one,
The location hole being rotatably assorted with locating shaft 410 is provided on the fixed part 100, the front end of locating shaft 410 passes through the location hole
It is connected as one with cue mark 521.It is rotatably connected in this way, both having realized between rotation section 200 and fixed part 100, simultaneously
Since rotation section 200, locating shaft 410 and 521 three of cue mark are connected as one, it is achieved thereby that rotation section 200 and instruction
The linkage of mark 521, when rotation section 200 is rotated using the central axis of locating shaft 410 as rotation axis, cue mark 521 is similary
It is rotated using the central axis of the locating shaft 410 as rotation axis, with the angular speed identical with rotation section 200,200 turns of rotation section
Dynamic angle is consistent with the angle that cue mark 521 rotates.
In addition, as shown in Figs. 1-2, in the above-described embodiments, the angular surveying structure also has that there are one be formed at fixation
100 surface of portion and the circular groove 540 concentric with the location hole, the cue mark 521 are placed in the groove 540 and by turning
Dynamic portion 200 is rotated by the drive of locating shaft 410 in the groove 540.Since the cue mark 521 of activity is placed in groove
In 540, the risk that cue mark 521 is destroyed by external force can be effectively reduced.
Based on the above technical solutions, the embodiment also further on the bottom surface of the groove 540 from it is lower toward
On be respectively provided with the first semicircle semicircle indicating piece 520 of indicating piece 530 and second, the described first semicircle indicating piece 530
And second color between semicircle indicating piece 520 it is identical but different from the color of 540 bottom surface of groove, the first semicircle indicating piece
530 are fixed on the bottom surface of groove 540 and its 531 and first true edge of straight flange, 110 keeping parallelism, the second semicircle indicating piece
520 straight flange is as 521 and second true edge of cue mark, 210 keeping parallelism, also, when the first true edge 110 and the
First semicircle indicating piece described in when 300 size of angle formed between two true edges 210 is zero and the second semicircle indicating piece
Just form a complete circle.By above-mentioned improvement so that the rotational structure of the measurable angle realizes a kind of very rich
Using effect ingenious (turns when the angle 300 formed between the first true edge 110 and the second true edge 210 is more than zero
Dynamic portion 200, which is relatively fixed portion 100 and rotates, makes angle 300 be more than zero), and the described first semicircle indicating piece 530 and second is semicircle
Indicating piece 520 is partly or entirely overlapped, and underlapped between the first semicircle semicircle indicating piece 520 of indicating piece 530 and second
Part make to be formed sector region that color protrudes on 540 bottom surface of groove (due to the first semicircle indicating piece 530 and second
Color is identical but different from the color of 540 bottom surface of groove between semicircle indicating piece 520, therefore the sector region color is made to dash forward
Go out), the angle of the sector region is the angle of the angle 300 formed between the first true edge 110 and the second true edge 210,
So that gauger can clearer, intuitively experience the size of tested angle.
As shown in Figs. 1-2, a kind of rotational structure of measurable angle described in above-described embodiment is also doubled as a kind of stationery
Box;Wherein, outer cover of the fixed part 100 as writing case, stationery storage bin of the rotation section 200 as writing case.Specifically, such as
Shown in Fig. 2, fixed part 100 includes upper cover 120, right side wall 130 and lower cover 140, the upper cover 120, right side wall 130 and lower cover
140 form a both ends and left open, the outer cover of remaining position closing, and rotation section 200 is adapted to simultaneously with the inner cavity of the outer cover
It can be extracted out by rotating from the left side of the outer cover, in this way, can taking and placing rotation section when rotation section 200 is extracted out from fixed part 100
Article in 200.
