Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
In conjunction with shown in Fig. 2,3,5, in the utility model embodiment, the universal protractor includes fanning strip 1, ruler 2, master
Ruler 3, vernier scale 4, base ruler 5, brake 6 and block 7.Wherein, the ruler 2 has measuring jaw 21, and the fanning strip 1 includes the
One basal plane 11 and the second basal plane 12, the ruler 2 are connect with the fanning strip 1, and the measuring jaw 21 of the ruler 2 and the sector
First basal plane 11 of plate 1 is adjacent to.The main scale 3 is slidably connected with the fanning strip 1 by the brake 6.The vernier scale 4
It is fixed on the fanning strip 1, specifically, existing therebetween certain after the vernier scale 4 is connect with the fanning strip 1
Gap, the main scale 3 are set in the gap, are equipped with scale on the vernier scale 4 and the main scale 3, when the main scale 3
When sliding, the scale on main scale 3 and vernier scale 4 cooperates reading, obtains measurement result.The base ruler 5 is set to the main scale 3
On, and the base ruler 5 is located at 12 side of the second basal plane of the fanning strip 1, preferably, the base ruler 5 is set to the main scale 3
End.The base ruler 5 include with the measuring jaw 21 of the ruler 2 cooperation measuring surface 51 and with the datum level of part 9 it is corresponding
Third basal plane 52, the measuring surface 51 connects with the third basal plane 52, preferably, the measuring surface 51 and the third base
Face 52 is vertical, and the third basal plane 52 is parallel with the datum level of the part 9.The block 7 is set on the base ruler 5, institute
Block 7 is stated equipped with a plane 71 being close to the third basal plane 52, also, the plane 71 is along away from described second
The direction of basal plane 12 extends, and is in a L between the measuring surface 51 of the base ruler 5 and the plane 71 of the block 7 in other words
Type.
As shown in Fig. 2, when carrying out angle measurement to part 9 using universal protractor described in the present embodiment, first by zero
One side of the angle to be measured of part 9 and the measuring jaw 21 of ruler 2 are adjacent to, then slide main scale 3, make the third basal plane 52 of base ruler 5 be adjacent to
The another side of angle is surveyed, meanwhile, so that the plane 71 of block 7 is adjacent to the datum level of part 9, due to the third of plane 71 and base ruler 5
Basal plane 52 is adjacent to, therefore, the third basal plane 52 of the datum level that also corresponds to part 9 and base ruler 5 in the same plane, finally, logical
It crosses the scale shown on main scale 3 and vernier scale 4 to be read, obtains the angle of angle measurement.
By above structure, universal protractor in the present embodiment, by using the plane 71 and base ruler 5 made on block 7
Third basal plane 52 be close to and plane 71 is along extending away from the direction of second basal plane 12 so that plane 71 and base ruler 5
Measuring surface 51 forms the scheme of L-type, solves in the prior art, and the third basal plane 52 of the base ruler 5 of universal protractor can be according to
The benchmark leaned on, when in use so as to cause personnel, the datum level of third basal plane 52 and part 9 are easy to appear mistake during contraposition
The problem of position, improve the accuracy of measurement of universal protractor.It, can be in addition, since personnel are when using the universal protractor
By the quick auxiliary positioning of plane 71, therefore also improve the convenience and efficiency of operation.
Specifically, as Figure 2-3, the shape of the fanning strip 1 is fan-shaped, there is a thickness, first basal plane
11 are located at the side of the fanning strip 1, and second basal plane 12 is located at the other side of the fanning strip 1, first basal plane 11
One end and one end of second basal plane 12 connect, the other end of first basal plane 11 and second basal plane 12 respectively with
The arc side of the fanning strip 1 connects.First basal plane 11 with the measuring jaw 21 of the ruler 2 for being close to, second basal plane
12 for universal protractor when returning to zero, for the base ruler 5 have against datum level, that is to say, that when rotation main scale 3 is to making base ruler
5 and second basal plane 12 against when, zero setting can be carried out to universal protractor.
Specifically, as shown in figure 3, the longitudinal section of the base ruler 5 is substantially trapezoidal, the upper bottom surface of the base ruler 5 with it is described
Main scale 3 connects, and the bottom surface of the base ruler 5 is measuring surface 51, and the third basal plane 52 of the base ruler is vertically connected at described simultaneously
Upper bottom surface and the bottom surface, that is, measuring surface 51.For installing the block 7 there are two being set on the third basal plane 52 of the base ruler 5
Mounting hole 53, preferably, the mounting hole 53 be threaded hole.Further, as illustrated in figures 4-5, the block 7 is substantially in length
Cube, the block 7, the plane 71 on the block 7 are close to the third basal plane 52 of the base ruler 5, and the block 7 is along its width
It is set on degree direction there are two through-hole 72, two through-holes 72 are corresponded with two mounting holes 53 respectively.Specifically,
In order to ensure plane 71 can extend a certain distance along the direction away from second basal plane 12, part 9 is limited with meeting
Reliability, in other words, in order to ensure plane 71 can exceed the enough length of third basal plane 52 towards the direction where measuring surface 51
Degree, the highly preferred height slightly larger than the base ruler 5 of the block 7, the height of the block 7 is deviateed at the midpoint of the through-hole 72
The center line in direction is spent, i.e., shown in fig. 5, the through-hole 72 is located at the center line position on the upper side of the short transverse of the block 7
It sets, so can both meet the reliability that the plane 71 of the block 7 limits part 9, the volume of block 7 can also be reduced.
Specifically, as shown in Fig. 2, the block 7 and the base ruler 5 are attached by M3 milled screw 8, since M3 is rolled
The head of flower screw 8 is bigger, and has annular knurl, is loaded and unloaded manually convenient for personnel, it can be achieved that quick when block 7 is replaced
Dismounting.
Specific embodiment is applied in the utility model to be expounded the principles of the present invention and embodiment, with
The explanation of upper embodiment is merely used to help understand the method and its core concept of the utility model；Meanwhile for this field
Those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application range, comprehensive
Upper described, the content of the present specification should not be construed as a limitation of the present invention.
